Personality and pediatric bipolar disorder: Toward personalizing psychosocial intervention

•Investigation of personality trait profiles in pediatric bipolar disorder.•Five factor personality inventory-child used to assess dimensions of personality.•Affected youth showed low emotion Regulation, conscientiousness and agreeableness.•Youth at risk for bipolar disorder should be targeted for psychosocial interventions. Previous research suggests that challenging temperament characteristics (i.e., low mood, irritability and rigidity) are associated with risk for the development of Pediatric Bipolar Disorder (PBD). This study aimed to investigate the connection between PBD and discrete dimensions of the Five Factor Model (FFM) of personality. Youth diagnosed with PBD I, II, or NOS, at high risk for the disorder (BD-HR) and healthy controls were recruited from the Child and Adolescent Psychiatry Outpatient Clinic at Stanford University School of Medicine. Researchers administered a personality inventory and evaluated current mood state. BD and BD-HR youth scored lower in Emotional Regulation than did HC youth (F (3, 70) = 10.75, p < .001). Within the BD and BD-HR groups, youth with high depression scores scored lower on Extraversion (F (3, 70) = 8.62, p < .001) and Conscientiousness (F (3, 70) = 4.53, p < .01). A major limitation of this study is its cross-sectional design, precluding analysis of whether certain traits or clusters of traits predict PBD or other mood disorders. Low Emotional Regulation, Conscientiousness, and Agreeableness were associated with PBD; this personality profile clinically corresponds with youth diagnosed with PBD who present with difficulty regulating their emotions, vulnerability to stress, and emotional reactivity. Future research examining personality characteristics in PBD may elucidate further a specific profile to aid clinicians in developing psychosocial interventions for youth with and at high risk of developing PBD.
