Protected: Chapter 2: History-taking

Opening

Dr. Martinez has explored why Mrs. Noor is here, what she fears, who knows, and what she hopes for. She has a picture — incomplete, but grounded in the patient’s own words. Now comes the next question: what exactly is she experiencing?

“I’d like to understand better what you’ve been going through,” Dr. Martinez says. “Can you describe what happens — in your own words, at your own pace?”

Mrs. Noor is quiet for a moment. Then: “It’s like — there’s a glass wall. Between me and everything. I can see my life but I can’t feel it.”

The exploration phase asked why the patient is here. History-taking asks what they are experiencing. But it does more than collect information. As the patient describes their complaint, the clinician’s mind is already working — forming hypotheses, testing them against what emerges, revising them with each new detail. History-taking is the second cycle of clinical reasoning: the patient tells their story in their own words, and the clinician listens for patterns that will guide further assessment.

Two Dimensions of History-Taking

Every question in this chapter serves two purposes at once. The first is substantive: each item explores a domain of the patient’s experience that matters clinically — what the complaint feels like, what worsens it, what relieves it, what came before. The second is cognitive: each item feeds the diagnostic reasoning process that runs in the clinician’s mind while listening. The nature of the complaint generates hypotheses. The daily course narrows them. The modifying factors test them. The treatment history revises them. The family history recalibrates the probabilities.

This is not unique to mental health — the same dual process operates in all medical history-taking. But in mental health, the cognitive dimension is more consequential, because there are no blood tests, no scans, no biomarkers to fall back on. What the patient tells you is what you have. The history alone yields the correct diagnosis in approximately 76–80% of cases across medicine.^1,2 In psychiatry, where the interview is simultaneously history, examination, and test, the percentage is likely higher — and the cost of listening poorly is accordingly greater.

Psychiatrists form diagnostic impressions early — often within the first three minutes.³ This is not a flaw but a feature of clinical expertise: experienced clinicians recognise patterns rapidly, drawing on accumulated experience to generate hypotheses from minimal cues.^4,5 The danger is not early hypothesis formation but early closure — settling on the first pattern that seems to fit and interpreting everything that follows as confirmation.⁶ In psychiatry, premature closure is the most common cognitive cause of diagnostic error — and psychiatric diagnostic error has been systematically underrepresented in patient safety research.⁴³ The consequences are substantial: anxiety disorder diagnoses in primary care may be incorrect in up to 60% of cases; bipolar disorder takes an average of 5 years to be correctly diagnosed for bipolar I and up to 11 years for bipolar II, with roughly 70% of patients initially misdiagnosed as having unipolar depression.^7,44

Every item in this chapter is shaped by cultural context. How distress is expressed, what constitutes a “trigger,” how help has been sought, what substances are normative, how family history is discussed — all vary across cultures. The heuristic structure is universal; the content it elicits is not. The clinician’s task is to use the structure while remaining open to culturally different ways of experiencing and communicating distress. The relevant sections below note where cultural variation is most important to recognize.

The 15 items that structure this chapter exist to prevent that. They are not a checklist to be completed but a set of heuristics — organised lines of inquiry that keep the clinician’s reasoning open while the patient’s story unfolds. Follow the patient’s narrative, not the item sequence. But know what each item does for your thinking, so that when the patient falls silent, you know which question will most usefully test what you are beginning to suspect.

Framework Box: The Clinician’s Mind During History-Taking

The GP handbook presents the three cycles of clinical reasoning in full: generating hypotheses from the patient’s story (Cycle 1), refining and testing them through structured inquiry (Cycle 2), and checking what might have been missed through systematic review (Cycle 3). The underlying strategy is the same in mental health — but the distribution across chapters is different.

In general practice, all three cycles often occur within a single consultation. In mental health, Cycle 1 (exploration) is Chapter 1. Cycle 2 (history-taking) is this chapter. Cycle 3 (systematic review) spans three scales: examination of experience (Scale 3), psychiatric examination (Scale 4), and socio-emotional context (Scale 5). This means Chapter 2 can be shorter than its GP counterpart, because much of what the GP chapter covers is handled in Chapters 3, 4, and 5.

What runs through all three cycles is a dual process that Croskerry describes: fast pattern recognition (System 1) and slow analytical reasoning (System 2) operate simultaneously, with the clinician oscillating between them.^4,5 Pattern recognition works well for typical presentations and experienced clinicians. It fails with atypical presentations, comorbidity, and cultural unfamiliarity. The heuristic structure of the MAAS items supports both processes — giving pattern recognition the data it needs while imposing enough structure to engage analytical reasoning when patterns mislead.

Bordage showed that clinicians who translate patient language into abstract clinical concepts — what he called semantic qualifiers — show superior diagnostic competence.^8,9 When Mrs. Noor says “glass wall,” the clinician hears depersonalisation. When she says “my hands don’t feel like mine,” the clinician hears somatic depersonalisation. When she says “I’m going through the motions,” the clinician hears collapsed intentional arc or emotional numbing. The translation is not a replacement of the patient’s words but an enrichment — the clinician holds both the patient’s language and the clinical concept, and the tension between them is where diagnostic reasoning lives.

Scale 2 has 15 items, organised around the same heuristic structure as the GP scale: the complaint itself, what modifies it, its broader pattern, its history, and its context. The table below shows the structure:

Section I: The Complaint (2.1–2.4)

The patient has told you why they are here. Now ask them to describe what they are experiencing — not in clinical terms, but in their own. The four items in this section follow the complaint heuristic: what does it feel like, how bad is it, when does it change, and how has it developed over time. For your reasoning, this is where hypotheses are generated. The patient’s language — the specific words they choose, the distinctions they make, the things they struggle to articulate — is the richest source of diagnostic information you will receive.

2.1 Asks about the nature of the complaint

The physician asks what the complaint feels like — its subjective quality and character. “Can you describe what this feels like for you?”

Let the patient find their own words before offering any. Their language is diagnostic data, not just a starting point. Ratcliffe demonstrated through phenomenological analysis that depression is not one experience but many: patients describe feeling “dead,” “distant,” “detached,” “cut off,” “suffocated,” “overwhelmed” — each pointing to different underlying structures of experience that current classification systems do not distinguish.¹⁰ “Sad” suggests depressed mood. “Empty” may point to depersonalisation or demoralization. “Numb” could be dissociative. “Heavy” suggests somatic presentation. “Nothing feels real” raises a different differential entirely.

For your reasoning, this is the first branching point. The word the patient uses generates the initial hypothesis set — and research shows that clinicians whose initial hypothesis set includes the correct diagnosis reach it 96% of the time.¹¹ Get this wrong and everything that follows confirms the wrong pattern.

In many cultures, psychological distress is expressed primarily through the body — headache, chest tightness, body heat, “nerves” — not because the patient lacks psychological vocabulary but because somatic idioms are the culturally normative way to communicate suffering. When a patient describes physical symptoms without “emotional” language, explore the experience behind the words rather than assuming a purely somatic presentation.

Some patients struggle to articulate inner experience. This is not evasion or low intelligence — alexithymia, the difficulty identifying and verbalising feelings, is present in over 40% of patients with anxiety, depression, and psychotic disorders.¹² When a patient says “I don’t know how to describe it” or “I just feel bad,” gentle contrasts can help: “Is it more like sadness, or more like absence?” But recognise that the struggle to name experience is itself clinically informative — it is common in depression, trauma, and personality presentations.

2.2 Asks about intensity

The physician asks about the severity of the complaint. “How much is this affecting what you can do?”

Notice the phrasing. The question asks about functional impact, not about a number on a scale. You have probably relied on severity scores — PHQ-9, GAD-7, a clinical impression of “moderate” or “severe” — as proxies for how much a patient is affected. But symptoms and functioning are surprisingly independent: a patient who scores “moderate” on a depression questionnaire but has stopped working, stopped seeing friends, and stopped reading to her children is more impaired than the score suggests. Another patient with a “severe” score may still be managing.¹³ Functional improvement often lags behind symptom improvement — meaning a patient whose PHQ-9 drops from 18 to 10 but who still cannot return to work has not recovered.

For your reasoning, intensity calibrates urgency. But the calibration works better through behaviour than through numbers. Ask what they have stopped doing, what requires effort that used to be automatic, what their worst moments look like. The narrowing of life — the giving up of activities, relationships, pleasures — is often the more reliable severity indicator.

2.3 Asks about the daily course

The physician asks how the complaint varies through the day. “Does this change during the day? Is it worse at certain times?”

Diurnal variation is a biological marker disguised as a simple question. Worse in the morning and improving through the day suggests melancholic depression — a pattern reflecting circadian rhythm disruption.¹⁴ But the clinical picture is more complex than textbooks suggest: in a large study of patients with major depression, only 33% reported morning worsening, 19% afternoon, and 48% evening.¹⁴ Worse at night suggests trauma-related or dissociative processes — sleep disturbances occur in 80–90% of PTSD patients, and the hyperarousal of trauma makes nighttime a time of increased vulnerability.¹⁵ Worse when alone suggests relational factors. No variation at all may indicate severity — or a different kind of condition.

For your reasoning, the daily pattern narrows hypotheses. It does something else too: it reveals something the patient may not have noticed themselves. “You mentioned it’s worst at night. What happens at night that’s different?” — the question invites the patient to reflect on a pattern they live inside but have not yet examined.

2.4 Asks about history over time

The physician asks when the complaint started, how it has changed, and whether there have been symptom-free intervals. “When did this first start? Has it been constant, or have there been better and worse periods?”

The longitudinal course is one of the strongest diagnostic and prognostic tools in psychiatry. A single episode differs fundamentally from recurrent episodes — each recurrence predicts faster future recurrence, and after three or more episodes, maintenance treatment is likely indicated.¹⁶ Gradual onset differs from sudden. Symptom-free intervals suggest episodic illness; continuous deterioration suggests something progressive. McGorry’s clinical staging model proposes that the same diagnosis at different stages requires different treatment intensity — a first episode (Stage 2) is a different clinical situation from chronic treatment-resistant illness (Stage 4).¹⁷

In mental health, patients often cannot date onset precisely — symptoms merge into personality, personality into identity: “I don’t know when it started. I think I’ve always been this way.” This is itself diagnostic. When a patient cannot separate the illness from themselves, it suggests early-onset persistent depression, characterological features, or developmental trauma — not episodic mood disorder.^18,19

For your reasoning, the longitudinal course is a hypothesis filter. A first episode with clear onset and precipitant points in one direction. A recurrent episode without precipitant points in another — Kendler showed that early episodes are typically triggered by major life stress, but with successive recurrences, the association progressively weakens until episodes occur autonomously.^20,21 The absence of a trigger in a recurrent episode is not a mystery. It is the expected consequence of neurobiological sensitisation.

Mrs. Noor

“What does it feel like?”

“Like there’s a glass wall between me and everything. I can see things, hear things, but they don’t reach me. My hands don’t feel like my own sometimes.”

“When is it worst?”

“At night. When the children are in bed and the house is quiet. During the day I’m busy — teaching distracts me. But the evenings —” she trails off.

“And when did this start?”

“It got bad six months ago, after — after what I told you about. But honestly, I think something like this happened before. When I was about fifteen. For a while things felt unreal. I thought everyone felt that way. It went away on its own.”

Listen to what Dr. Martinez’s mind is doing. “Glass wall” — depersonalisation, possibly derealization. “Hands don’t feel like mine” — somatic depersonalisation, extending beyond emotional numbing to the body. Worst at night when quiet — consistent with dissociative processes, which thrive in the absence of external stimulation. Onset six months ago after an encounter with someone “from before” — possible trauma reactivation. A previous episode at fifteen that resolved spontaneously — this is not a new phenomenon but a recurrence, with a vulnerability that predates the current trigger. The hypothesis set is forming: dissociative depersonalisation, likely trauma-related, with a recurring pattern suggesting an underlying vulnerability rather than a situational reaction. These hypotheses will be tested further in the sections that follow and systematically examined in Chapters 3, 4, and 5.

Section II: What Affects It (2.5–2.8)

Once the patient has described what they experience, the next question is: what makes it better, what makes it worse, what triggered it, and what keeps it going. These four modifying factors serve two functions. Substantively, they connect the complaint to the patient’s life and point directly toward treatment. Cognitively, they test hypotheses. If your working hypothesis is depersonalisation following trauma reactivation, you would expect worsening in quiet, unstructured settings and improvement with relational contact. If the pattern is different — worsening with social contact, improvement alone — your hypothesis needs revision.

2.5 Asks about provoking factors

The physician asks what triggered the complaint. “What do you think set this off?”

This overlaps with 1.8 (recent life events) but goes deeper: not just what happened externally, but what internal or external factors preceded the onset. The stress-diathesis model, originally developed by Zubin and Spring for schizophrenia and since extended to all psychiatric disorders, proposes that the higher the vulnerability, the lower the level of stress needed to trigger an episode.²² A major depressive episode following a minor stressor tells you something about the threshold — and therefore about the underlying vulnerability.

Some episodes have no identifiable trigger. This is not unusual, and it does not mean the patient is exaggerating. In recurrent illness, episodes increasingly occur without clear precipitants — the kindling effect means the brain has become sensitised through previous episodes and can generate episodes autonomously.^20,21 The absence of a trigger in a recurrent episode is itself a finding: it suggests biological sensitisation rather than a “missing” precipitant. For a first episode without a trigger, consider biological factors: thyroid dysfunction, substances, medical conditions.

2.6 Asks about increasing factors

The physician asks what makes the complaint worse. “What makes it worse?”

The patient often knows what worsens their symptoms even when they don’t know the cause. And what they describe reveals the maintaining mechanism. If avoidance worsens anxiety, you are seeing the safety behaviour cycle — Salkovskis demonstrated that the very strategies patients use to reduce anxiety paradoxically maintain it, because they prevent the patient from learning that the feared outcome would not have occurred.²³ If “thinking about it” worsens depression, you are seeing rumination — Nolen-Hoeksema showed that repetitive focus on depressive symptoms exacerbates them, impairs problem-solving, and erodes social support.^24,25 If isolation worsens everything, you are seeing the social withdrawal cycle common across conditions. If poor sleep worsens symptoms, this is both a maintaining factor and a treatment target — Harvey showed that sleep disruption and affect dysregulation form a bidirectional vicious circle.²⁶

For your reasoning, the worsening factor often points directly to what treatment should target. It is also a hypothesis test: the conditions under which symptoms worsen should be consistent with the hypothesised mechanism. If depersonalisation worsens in quiet and improves with distraction, that is consistent with a dissociative mechanism. If it worsened with social contact, you would need to reconsider.

2.7 Asks about maintaining factors

The physician asks what keeps the complaint going. “What do you think keeps this going?”

This is the most therapeutically important of the modifying factors, because maintaining factors are what treatment targets. Avoidance maintains anxiety by preventing disconfirmation.²³ Rumination maintains depression through multiple mechanisms: it enhances negative thinking, impairs problem-solving, interferes with doing things that would actually help, and drives people away.^24,25 Concealment maintains isolation by preventing the corrective experience of being known and accepted. Substance use provides short-term relief and long-term deterioration.

The patient usually does not recognise maintaining factors as such — they experience them as coping. A patient who avoids social situations to manage anxiety feels safer, not stuck. A patient who ruminates feels like they are trying to figure things out, not making things worse. The paradox is central: what helps in the short term perpetuates the problem. Explore collaboratively: “Sometimes the things that help us survive a problem also keep it going. Has that been your experience?”

For your reasoning, maintaining factors are where substantive understanding and clinical reasoning converge. They explain why the condition persists despite the patient’s desire to recover, and they point to what the formulation in Chapter 6 must address.

2.8 Asks about decreasing factors

The physician asks what makes the complaint better. “What helps? Is there anything that makes it better, even temporarily?”

Relieving factors reveal resources — and the mechanism of relief is itself diagnostic. A patient who feels better around her children has a relational anchor that treatment can build on. A patient who improves with activity has a behavioural pathway. A patient who finds relief only in sleep or alcohol is telling you about both severity and self-medication. When a patient cannot identify anything that helps, that is a specific clinical finding — anhedonia, the inability to experience pleasure or relief, is a hallmark of melancholic depression and predicts poorer treatment response.²⁷

Spontaneous improvement toward evening in the absence of any apparent cause is also informative — it suggests circadian-driven depression rather than situationally determined mood.¹⁴

Mrs. Noor

“What makes it worse?”

“Quiet. Being alone. Night-time. When I have nothing to do and my mind — goes to places.”

“And what helps?”

“Being busy. Teaching helps, because I have to be present for the children. And my own children — when my daughter climbs into my lap, sometimes for a moment I can feel her. It’s brief, but it’s there.”

“What do you think keeps this going?”

A long pause. “I don’t talk about it. I don’t talk about any of it. I just — carry it.”

Three findings, and notice how each tests the working hypotheses. The symptom worsens with isolation and quiet — consistent with dissociative processes, which thrive in unstimulating environments. It improves with relational contact — her children can briefly break through the glass wall, confirming that the depersonalisation is not absolute but context-dependent. And it is maintained by concealment — she carries everything alone, which prevents the corrective experience of being known. Each finding both deepens the substantive picture and confirms or refines the diagnostic reasoning. Each will inform the formulation and treatment plan in Chapter 6.

Section III: The Wider Picture (2.9)

2.9 Asks about accompanying symptoms

The physician asks whether other symptoms accompany the main complaint. “Are there any other symptoms that come along with this?”

Mental health conditions rarely occur alone. Comorbidity is not the exception but the rule — the National Comorbidity Survey found that most people with one disorder have at least one other, and those with serious disorders frequently have several.²⁸ Barlow and Harvey independently argued that common processes — emotional reactivity, avoidance, cognitive distortion — underlie multiple conditions, which explains why they so often co-occur.^29,30

For your reasoning, accompanying symptoms can broaden the differential or redirect it entirely. A patient presenting with anxiety who also has sleep disruption, concentration problems, and irritability may have generalised anxiety — or may have an emerging bipolar mixed state. A patient with depersonalisation who also has insomnia, emotional numbing, and difficulty concentrating may have dissociative symptoms — or may be describing the cognitive and affective flatness of depression. The pattern of co-occurrence is informative: depression plus anxiety suggests shared emotional vulnerability; depression plus substance use suggests self-medication; psychosis plus substance use requires clarification of which came first.

In general practice, this item leads to a systematic review of systems. In mental health, that systematic review is substantially larger — it spans the examination of experience (Scale 3), psychiatric examination (Scale 4), and socio-emotional context (Scale 5). Item 2.9 opens the door to Cycle 3; the next three chapters walk through it.

Mrs. Noor

“Besides the feeling of being behind glass — are there other things?”

“I can’t sleep. I mean, I fall asleep but I wake up at two or three and then I can’t get back to sleep. My mind just — runs. And I’m tired all the time. And sometimes I look at my hands and they don’t look like mine.”

Insomnia with early-morning waking, fatigue, depersonalisation extending to the body. The clinician’s hypothesis set now includes at least two possibilities that require careful differentiation: dissociative depersonalisation (trauma-related, with the body involvement and nocturnal worsening) and depressive depersonalisation (with the insomnia, fatigue, and emotional flatness). Both are plausible; both are consistent with the available data. The distinction will require the systematic examination of Chapters 3 and 4 — which is exactly what the third cycle of clinical reasoning is for.

Section IV: Treatment History (2.10–2.12)

A patient arriving for a mental health assessment often has a history — of previous episodes, previous treatments, and previous clinicians. That history is both clinical data and lived experience. It changes what is likely, what has been tried, and what the patient is willing to try again. For your reasoning, treatment history revises hypotheses: a patient who did not respond to multiple antidepressants may have a wrong diagnosis rather than treatment resistance. For the patient, treatment history shapes what they expect — and expectations independently predict outcomes.³¹

2.10 Asks about past mental health problems

The physician asks about previous mental health difficulties. “Have there been other times in your life when you struggled like this?”

Previous episodes are the single strongest predictor of future episodes. Solomon’s 10-year prospective follow-up showed that a greater number of prior episodes was the strongest baseline predictor of recurrence speed, and that patients with three or more prior episodes recurred significantly faster.¹⁶ This makes episode counting not an administrative exercise but a prognostic tool — it determines whether the patient needs acute treatment or maintenance treatment, and how aggressively to plan for relapse prevention.

Help-seeking patterns vary across cultures. In many communities, mental health difficulties are first addressed through religious leaders, traditional healers, family elders, or community support rather than through formal mental health services. “Have you had mental health problems before?” may miss this entirely. Ask also: “Have you ever talked to anyone about these kinds of difficulties — a doctor, a counselor, a religious leader, someone in your family?”

Ask broadly. Many patients have had episodes that were never formally diagnosed — periods of withdrawal, months of not coping, unexplained physical symptoms. A patient who reports “a bad patch after university” may be describing an untreated depressive episode. Ask about the quality of previous recoveries too: full remission versus residual symptoms. Residual symptoms predict faster recurrence — the patient who “never quite got back to normal” is at higher risk than the one who recovered fully.³²

2.11 Asks about past professional treatment

The physician asks about previous treatment and its effects. “What treatment have you had before? Did it help?”

What a patient has tried before, and what happened, must be interpreted carefully. The current international consensus defines treatment-resistant depression as inadequate response to at least two antidepressant trials of adequate dose and duration.^33,34 But the concept of “pseudoresistance” reminds us that many apparent failures reflect inadequate trials, wrong diagnoses, or unaddressed comorbidity rather than true biological resistance — at least 30% of patients with depression meet criteria for treatment resistance, and in many of them the resistance is to the wrong treatment rather than to treatment itself. Before accepting that something “didn’t work,” ask: Was the dose adequate? Was the duration sufficient? Was the diagnosis correct?

Ask not just about pharmacology but about experience. A patient who felt unheard by a previous therapist will approach therapy differently from one who felt supported but not improved. A patient who started therapy but dropped out after two sessions may have encountered something they were not ready for — or may have had a bad therapeutic experience that now colours all expectations. The patient’s experience of past treatment is relational data, not just treatment data.

2.12 Asks about current professional consultations

The physician asks about ongoing care from other professionals. “Are you seeing anyone else at the moment?”

Patients in mental health care often see multiple professionals: GP, psychologist, social worker, psychiatrist, sometimes alternative practitioners. Care fragmentation — multiple providers with minimal coordination — is the norm in mental health, and research consistently shows it worsens outcomes: more hospitalisations, more emergency visits, greater medication errors, and higher costs.^35,36 Map the current care landscape. With the patient’s consent, communicate with other providers. Fragmented care is not the patient’s fault but harms them — and it means the patient has been telling their story from the beginning to each new clinician, a burden that itself can be exhausting.

Section V: Substances, Function, and Family (2.13–2.15)

2.13 Asks about medication and substance use

The physician asks about current prescribed medication, self-medication, and substance use. “What medications are you taking? And any other substances — alcohol, cannabis, anything else?”

Substances interact with mental health in multiple directions: they can cause symptoms, mask them, maintain them, or represent the patient’s best available coping strategy. Khantzian’s self-medication hypothesis proposes that people with substance use disorders are not reckless but suffering — they discover that specific substances relieve specific distress: alcohol dampens anxiety and emotional pain, stimulants counter depression and anhedonia, opioids numb both emotional and physical suffering.³⁷ A patient drinking two glasses of wine every night to fall asleep is self-medicating insomnia — the alcohol is clinical data, not a moral judgment.

Substance norms are culturally shaped. Alcohol use ranges from prohibited to socially expected depending on religious and cultural context. Khat, betel nut, and other regionally specific substances may not be captured by standard screening questions. Ask about all substances the patient uses, including those they may consider normal rather than noteworthy.

For your reasoning, the temporal relationship is essential: did the substance use precede the psychiatric symptoms, or did the symptoms come first? Alcohol-induced depression differs from depression with secondary alcohol use. Cannabis use has a dose-response relationship with psychosis risk — heavy users have nearly four times the risk of psychotic outcomes.³⁸ And substances can mimic psychiatric conditions: excessive caffeine mimics anxiety, alcohol withdrawal mimics panic, stimulants mimic mania, cannabis can produce paranoia and depersonalisation. Ask directly and without judgment, every time.

2.14 Asks about functionality

The physician asks whether the complaint serves a function in the patient’s life. “Has being unwell changed anything in your relationships or daily life?”

This is a delicate item. The concept of secondary gain has psychoanalytic origins and limited empirical validation — Fishbain reviewed the literature and found that of 166 references, only 14.5% were actual scientific studies.³⁹ But the clinical reality it points to is real: when van Dijk studied 166 psychiatric outpatients, 42% reported expecting secondary gains from their illness, and those patients had significantly worse therapy outcomes — yet only 6% had disclosed this to their psychiatrist.⁴⁵ A patient whose illness generates care from an otherwise distant partner has a powerful maintaining factor. A patient whose anxiety keeps them from a workplace they find intolerable may not be eager to “recover.”

What matters is how you frame this. Secondary gain and maintaining factors (2.7) overlap substantially, and the maintaining factor frame is clinically more useful and less blaming. The function of illness is usually outside the patient’s awareness. Frame collaboratively: “Sometimes when people are unwell, some things in life become easier — fewer demands, more support from others. This doesn’t mean the illness isn’t real. But it can make recovery more complicated. Has anything like that happened?”

2.15 Asks about family history

The physician asks about hereditary and familial aspects. “Does anyone in your family have similar problems?”

Family history in psychiatry carries both genetic and experiential weight. The heritability of major psychiatric disorders is substantial — 60–85% for bipolar disorder and schizophrenia, around 37% for major depression.⁴⁰ First-degree relatives of individuals with bipolar disorder or schizophrenia have 6–10 times the population risk. But genetics is not destiny: 15–40% of risk derives from environmental sources, and the genetic contribution operates through vulnerability, not determination.

What makes this item clinically rich is what it means to the patient. A patient whose mother had schizophrenia may be terrified that they are developing it. A patient whose father drank himself to death may recognise the same pattern and feel helpless. The family history is not just a risk factor — it is the patient’s own model of what mental illness does to a life, and that model shapes what they fear, what they expect, and what they are willing to try.

And beyond genetics: growing up with a depressed parent teaches patterns of affect regulation, coping, and relational behaviour that increase risk independent of heritability. Yehuda demonstrated that trauma can produce epigenetic changes — alterations in gene expression — that are transmitted to the next generation.⁴¹ The family history is not just what runs in the family but what the family has been through.

Some patients do not know their family history — adoption, estrangement, or cultural silence about mental illness. In many cultures, mental illness carries intense stigma and is not discussed within families; a patient may genuinely not know about affected relatives. Family structure also varies — extended family, multiple households, migration-separated families. Ask about the family the patient grew up in, not just the nuclear family assumed by Western norms. Note gaps rather than assuming absence.

Mrs. Noor

“Are you taking any medication currently?”

“I stopped the sertraline. It wasn’t doing anything and it made me feel more numb, which was the last thing I needed.”

“Any alcohol or other substances?”

“A glass of wine sometimes in the evening. Maybe more than I used to. It helps me fall asleep.”

“And in your family — has anyone had similar struggles?”

Mrs. Noor hesitates. “My mother had — they called it nerves. She spent a lot of time in bed when I was young. I don’t know if she was ever diagnosed with anything.”

Three findings that revise the diagnostic picture. The SSRI made the numbing worse — significant, because depersonalisation can worsen on serotonergic medication, which is consistent with the dissociative hypothesis and inconsistent with a straightforward depressive episode. Alcohol is emerging as self-medication — mild, but the trajectory matters. And the mother: “they called it nerves, she spent a lot of time in bed” — untreated maternal depression, or possibly something dissociative too. The family history opens both a genetic possibility and a developmental one: what was it like for a child to have a mother who spent a lot of time in bed? What did Mrs. Noor learn about what happens when you suffer?

Notice what the clinician’s mind has done across these five sections. It started with a broad hypothesis set (depersonalisation, depression, dissociation, trauma response). The complaint heuristic generated the initial pattern. The modifying factors tested it. The treatment history provided a natural experiment (SSRI worsened symptoms — a finding that favours one hypothesis over another). The family history added both biological risk and developmental context. By the end of Scale 2, Dr. Martinez has not a diagnosis but a well-formed set of hypotheses that can now be systematically examined in the three chapters that follow.

What Can Go Wrong

The checklist that replaces the conversation. The physician works through the items mechanically — nature, intensity, course, triggers — and the patient feels interviewed rather than heard. History-taking should follow the patient’s narrative, not impose a sequence. Use the items as a mental map, not a questionnaire. If the patient spontaneously describes maintaining factors while talking about the nature of the complaint, follow them there.

Premature closure. The patient mentions insomnia and low mood, and the clinician settles on depression before exploring further. This is the most common cognitive error in psychiatric diagnosis — and confirmatory search makes it worse. Mendel found that psychiatrists conducting a confirmatory information search made wrong diagnoses in 70% of cases, versus 27–47% for those who searched for disconfirming evidence.⁴² The 15 items exist to prevent this — each one may reveal something that changes the picture.

The history without a story. The clinician gathers facts — onset, duration, severity — but never asks the patient to describe their experience in their own words. Facts without phenomenology produce a diagnosis; facts with phenomenology produce understanding. “When did it start?” gives you a date. “What was happening in your life when it started?” gives you a context. Both are needed; the first without the second is a form.

The substance question that isn’t asked. Clinicians skip 2.13 out of discomfort or assumption. But a patient whose anxiety is alcohol-withdrawal, or whose psychosis is cannabis-induced, needs a fundamentally different treatment plan. Ask directly, every time.

The treatment history that is ignored. A patient arrives having tried two antidepressants, a benzodiazepine, and six sessions of CBT. If you do not ask what happened and why they stopped, you may recommend something they have already rejected — and they will not tell you, because they assume you read the file.

Reflection Prompts

1. When a patient describes their experience, do you listen for their words or for diagnostic categories? What happens when you hold both at once — the patient’s language and the clinical concept it evokes?
2. Think about a patient where your first hypothesis turned out to be wrong. What changed the picture? Was it something you asked, or something the patient volunteered?
3. How do you ask about substance use? Is your approach different with patients you assume do or do not use substances? Should it be?
4. Consider a patient who could not identify anything that helped. What did that tell you — about severity, about hope, about what treatment needed to address first?
5. When a patient says “I’ve always been this way,” do you accept it or explore further? What might lie behind that statement?

Key Points

• History-taking serves two purposes simultaneously: it explores the patient’s experience and it drives the clinician’s diagnostic reasoning. Every question collects information and tests a hypothesis
• The patient’s own words are diagnostic data — “sad,” “empty,” and “numb” point in different clinical directions. Let them find their language before offering yours
• Premature closure is the most common reasoning error in psychiatry — the 15 items exist to keep your thinking open while the patient’s story unfolds
• Maintaining factors are what treatment targets — and patients experience them as coping, not as part of the problem
• Treatment history is a natural experiment: what worked, what failed, and why tells you more about the diagnosis than the current presentation alone
• Family history carries genetic risk, developmental experience, and the patient’s own model of what mental illness does to a life. All three matter
• At the end of history-taking, you should have not a diagnosis but a well-formed hypothesis set that the systematic examination of Chapters 3, 4, and 5 will test

Closing

Dr. Martinez now has a detailed picture of what Mrs. Noor is experiencing: a glass wall between herself and the world, worst at night, relieved briefly by contact with her children, triggered six months ago but with a precedent in adolescence. The SSRI made it worse. She is drinking a little more. Her mother had something similar. She carries all of it alone.

The history has given Dr. Martinez hypotheses — depersonalisation as a dissociative response, possibly trauma-linked, with a previous episode suggesting vulnerability, and the SSRI response favouring a dissociative mechanism over a purely depressive one. But hypotheses are not yet understanding. What Mrs. Noor describes — “a glass wall,” “my hands don’t feel like mine,” “I’m going through the motions” — needs a more precise examination. What is the structure of this experience? Is this depersonalisation, or something else? How does it relate to her sense of self, her body, her relationship with time?

These questions cannot be answered by history-taking alone. They require the systematic examination that begins in the next chapter — where the third cycle of clinical reasoning opens, and where the patient’s struggle to articulate what has changed becomes the focus rather than the obstacle.
