Essential Elements of History Taking in Depression
When evaluating a patient with depression, conduct a systematic assessment covering psychiatric symptoms, medical history, psychosocial stressors, trauma exposure, suicidal ideation with specific risk factors, and family psychiatric history, following the structured approach outlined in the APA psychiatric evaluation guidelines 1.
Core Psychiatric Assessment
Current Mental Status and Symptom Profile
- Mood and affect: Document current mood state, level of anxiety, and emotional range
- Thought content and process: Assess for cognitive distortions, rumination, and thought patterns
- Hopelessness: Specifically evaluate feelings of hopelessness as a key prognostic indicator 1
- Speech patterns: Note fluency, articulation, rate, and volume
- Perception and cognition: Screen for psychotic symptoms or cognitive impairment
Suicidal Risk Assessment (Critical Component)
When depression is present, you must systematically evaluate 1:
- Current suicidal ideation: Active versus passive thoughts of death or suicide
- Specific suicide plans: Method, timing, location
- Access to lethal means: Particularly firearms
- Intended course of action if symptoms worsen
- Motivations for suicide: Attention-seeking, revenge, shame, delusional guilt, command hallucinations
- Protective factors: Reasons for living (children, religious beliefs, future plans)
- Quality of therapeutic alliance: Your relationship strength affects risk
Aggressive Ideation
If present, assess 1:
- Thoughts of physical or sexual aggression toward others
- Homicidal ideation
- Past legal or disciplinary consequences of aggressive behaviors
Medical and Medication History
Current and Past Medical Conditions
Document systematically 1:
- All current medications: Prescribed, over-the-counter, herbal supplements, vitamins—and their side effects
- Drug allergies and sensitivities
- Relationship with primary care provider: Ongoing or absent
- Past/current medical illnesses and hospitalizations
- Neurological disorders: Any history of seizures, stroke, dementia, or neurocognitive symptoms
- Head injuries or physical trauma
- Endocrine disorders: Thyroid disease, diabetes
- Cardiopulmonary status
- Infectious diseases: HIV, hepatitis C, tuberculosis, sexually transmitted infections
- Chronic pain conditions
- Sexual and reproductive history
This medical review is essential because many conditions and medications can cause or exacerbate depressive symptoms 2.
Family Psychiatric History
For patients with suicidal ideation, specifically assess family history of suicide attempts or completions in biological relatives 1. Also document:
- Family history of depression, bipolar disorder, other psychiatric conditions
- Family history of substance abuse
- Family history of violent behaviors (if patient has aggressive ideation)
Personal and Social History
Psychosocial Stressors
Systematically evaluate 1:
- Financial problems
- Housing instability
- Legal issues
- School or occupational difficulties
- Interpersonal/relationship problems
- Lack of social support
- Terminal or disfiguring medical illness
Trauma History
Conduct a thorough trauma review 1:
- Childhood abuse (physical, sexual, emotional, neglect)
- Domestic violence exposure
- Combat exposure
- Assault or violent victimization
- Witnessing violence
Cultural and Contextual Factors
- Cultural background and beliefs about mental illness 1
- Need for interpreter services
- Cultural explanations for symptoms
- Religious or spiritual beliefs affecting treatment acceptance
Physical Examination Elements
Document 1:
- Height, weight, BMI: Changes may indicate severity
- Vital signs: Can reveal anxiety or medical comorbidity
- General appearance and nutritional status: Self-care, hygiene, grooming
- Skin examination: Look for stigmata of self-injury, cutting, substance use
- Coordination and gait: Rule out neurological causes
- Involuntary movements: Screen for medication side effects or neurological conditions
- Vision and hearing: Sensory deficits can contribute to depression
Common Pitfalls to Avoid
Missed diagnoses are common 3. Research shows patients often have multiple visits before depression is identified. To prevent this:
Don't rely solely on patient volunteering symptoms: Many patients present with somatic complaints (pain, fatigue, sleep disturbance, weight changes) rather than stating "I'm depressed" 2
Don't skip the suicide assessment: Even if the patient seems low-risk, systematic evaluation is mandatory when depression is present 1
Don't overlook recurrent depression: The majority of depressed patients have had prior episodes 3—ask specifically about past episodes and treatments
Don't assume you know the patient well enough to skip formal assessment: Even in established relationships, systematic evaluation prevents oversights 4
Don't forget to rule out secondary depression: Medical conditions, medications, and substance use can cause depressive symptoms 2
Practical Implementation
The evidence shows that primary care physicians often miss depression diagnoses despite multiple patient visits 3. Using a structured approach based on these APA guidelines 1 significantly improves detection. While family physicians may prefer relationship-based diagnostic approaches 4, incorporating systematic assessment of these elements ensures comprehensive evaluation without missing critical risk factors or treatable causes.
