Brief report: a family risk study exploring bipolar spectrum problems and cognitive biases in adolescent children of bipolar parents.

Children of parents with bipolar disorder are at increased risk of bipolar spectrum diagnoses. This cross-sectional study explores cognitive factors in the prediction of vulnerability to bipolar disorder. Adolescents at high-risk (with a parent with bipolar disorder; n = 23) and age and gender matched adolescents (n = 24) were recruited. Parent and adolescent diagnoses were evaluated (SCID and SADS-L). Adolescents completed self-report measures assessing attributional style (ASQ), appraisal of hypomania-relevant experiences (HIQ), and hypomanic personality/temperament (HPS). Despite limitations in the power of the study, significantly more adolescents at high-risk for disorder received bipolar spectrum diagnoses. Groups did not differ in attributional style, hypomanic temperament or appraisals of hypomania-relevant experiences. A trend in ASQ results and general implications are discussed. The current study suggests that familial risk of bipolar disorder is not inevitably associated with cognitive biases in adolescence.
