RESUMO
Family history of mental illness provides important information when evaluating pediatric bipolar disorder (PBD). However, such information is often challenging to gather within clinical settings. This study investigates the feasibility and utility of gathering family history information using an inexpensive method practical for outpatient settings. Families (N=273) completed family history, rating scales, and the Mini-International Neuropsychiatric Interview (Sheehan et al., 1998) and the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children (Kaufman et al., 1997) about youths 5-18 (median=11) years of age presenting to an outpatient clinic. Primary caregivers completed a half-page Family Index of Risk for Mood issues (FIRM). All families completed the FIRM quickly and easily. Most (78%) reported 1+ relatives having a history of mood or substance issues (M=3.7, SD=3.3). A simple sum of familial mood issues discriminated cases with PBD from all other cases (area under receiver operating characteristic [AUROC]=.63, p=.006). FIRM scores were specific to youth mood disorder and not attention-deficit/hyperactivity disorder or disruptive behavior disorder. FIRM scores significantly improved the detection of PBD even controlling for rating scales. No subset of family risk items performed better than the total. Family history information showed clinically meaningful discrimination of PBD. Two different approaches to clinical interpretation showed validity in these clinically realistic data. Inexpensive and clinically practical methods of gathering family history can help to improve the detection of PBD.

OBJECTIVE: Pediatric bipolar disorder (PBD) involves a potent combination of mood dysregulation and interpersonal processes, placing these youth at significantly greater risk of suicide. We examined the relationship between suicidal behavior, mood symptom presentation, family functioning, and quality of life (QoL) in youth with PBD. METHODS: Participants were 138 youths aged 5-18 years presenting to outpatient clinics with DSM-IV diagnoses of bipolar I disorder (n=27), bipolar II disorder (n=18), cyclothymic disorder (n=48), and bipolar disorder not otherwise specified (n=45). RESULTS: Twenty PBD patients had lifetime suicide attempts, 63 had past or current suicide ideation, and 55 were free of suicide ideation and attempts. Attempters were older than nonattempters. Suicide ideation and attempts were linked to higher depressive symptoms, and rates were even higher in youths meeting criteria for the mixed specifier proposed for DSM-5. Both suicide ideation and attempts were associated with lower youth QoL and poorer family functioning. Parent effects (with suicidality treated as outcome) and child effects (where suicide was the predictor of poor family functioning) showed equally strong evidence in regression models, even after adjusting for demographics. CONCLUSIONS: These findings underscore the strong association between mixed features and suicidality in PBD, as well as the association between QoL, family functioning, and suicidality. It is possible that youths are not just a passive recipient of family processes, and their illness may play an active role in disrupting family functioning. Replication with longitudinal data and qualitative methods should investigate both child and parent effect models.
