Simple Screening Questions for Bipolar Disorder in Primary Care
Ask about distinct periods of elevated mood with decreased need for sleep, plus inquire about family history of bipolar disorder and past episodes of depression. These core questions form the foundation of bipolar screening in primary care settings 1.
Core Screening Questions
The American Academy of Child and Adolescent Psychiatry establishes minimal standards for screening that apply equally well to adults 1:
Primary Questions (Ask These First)
"Have you ever had distinct periods—lasting at least several days—when your mood was unusually high, energetic, or irritable?"
- This targets the hallmark feature of bipolar disorder: discrete mood episodes that represent a clear departure from baseline
"During these times, did you need much less sleep than usual but still feel energetic?"
- Sleep disturbance with psychomotor activation is highly specific for mania/hypomania 1
"Has anyone in your family been diagnosed with bipolar disorder or manic depression?"
- Family history significantly increases pre-test probability 2
Secondary Questions (If Initial Screening Positive)
"During these high periods, did you engage in reckless or impulsive behaviors you wouldn't normally do?"
- Examples: excessive spending, sexual indiscretions, risky business decisions
"Have you had multiple episodes of depression in your life?"
- Recurrent depression warrants bipolar screening, as 75% of symptomatic time in bipolar disorder consists of depressive episodes 3
"Have you ever had suicidal thoughts or made a suicide attempt?"
- Critical for risk assessment; suicide rate is 0.9% annually in bipolar disorder versus 0.014% in general population 3
Important Clinical Context
When to screen: Screen any patient presenting with depression, anxiety, irritability, or recurrent mood symptoms 1, 2. The NICE guidelines specifically recommend asking about overactivity or disinhibited behavior in all adults presenting with depression 4.
Duration matters: If the elevated/irritable mood lasted 4 or more days, refer for specialist assessment 4. This distinguishes clinically significant hypomania from normal mood fluctuations.
Common pitfall: Patients rarely seek help for manic/hypomanic symptoms—they present for depression, anxiety, or fatigue 2. They often don't recognize hypomania as problematic. This is why proactive screening is essential rather than waiting for patients to volunteer manic symptoms.
What NOT to Rely On Alone
Irritability, reckless behaviors, and increased energy lack specificity and occur in many conditions including ADHD, PTSD, and disruptive behavior disorders 1. These symptoms support a diagnosis but shouldn't trigger referral by themselves without the core features of distinct mood episodes and sleep changes.
Next Steps After Positive Screen
Do not make a formal diagnosis of bipolar disorder in primary care 2. Refer to psychiatry, ideally a mood disorders specialist, for definitive diagnosis. The mean delay from first depressive episode to bipolar diagnosis is approximately 9 years 3, so early referral after positive screening can dramatically improve outcomes.
If urgent features are present (active mania, severe depression, danger to self/others), make an urgent psychiatric referral 4.
Practical Screening Tools (Optional)
While direct questioning is the standard, validated screening instruments can supplement clinical assessment:
- Mood Disorder Questionnaire (MDQ): Best accuracy with cut-off score of 5 (sensitivity 0.91, specificity 0.67) 5. High specificity (0.90) makes it useful for ruling in bipolar disorder 6
- Rapid Mood Screener (RMS): Newer, quick tool with sensitivity 0.88 and specificity 0.80 6
However, these tools should complement, not replace, direct clinical questioning about the core features outlined above.
