Consecutively assessed patients with diagnosis disorder or BP episodes completed the BPIIDQ-P at psychiatric outpatient clinic Hong Kong October December 2013. Data were analyzed using discriminant analysis logistic regression. Of 298 subjects recruited, 65 (21.8%) males 233 (78.2%) females.

Based on family history, age onset, postpartum episodic course, attacks anxiety, hypersomnia, social phobia agoraphobia, 8-item BPIIDQ-8 constructed. The differentiated those sensitivity/specificity 0.75/0.63 whole sample 0.77/0.72 female subgroup history childbirth. can differentiate secondary care level satisfactory good reliability validity. It has potential tool primary settings. Recall bias, relatively small size, high proportion females limit generalization results.
