Characterization of children of bipolar parents by parent report CBCL.

In past research the Child Behavior Checklist (CBCL) has differentiated among various diagnostic categories for children and adolescents. However, research has not been conducted on whether the CBCL differentiates among diagnostic categories for children at high risk for development of psychopathology. This study compares four diagnostic groups [bipolar disorder (BD), attention/deficit-hyperactivity disorder (ADHD), Depressed/Anxious and No Diagnosis] within a cohort of 58 children of bipolar parents to determine whether their CBCL scores will replicate the scores of children not at high risk for bipolar disorder. The cohort of children of bipolar parents received elevated scores on the CBCL scales in comparison with non-clinical populations. In addition, the CBCL distinguished between children of bipolar parents with and without clinical disorders. Finally the BD group differed from the ADHD group only on the Aggressive Behaviors, Withdrawn and Anxious/Depressed subscales of the CBCL. Therefore the CBCL did not discriminate between the BD and ADHD groups as it had in previous studies of children with BD and unspecified family history. It is possible that this discrepancy is due to a group of children of bipolar parents with ADHD who are currently prodromal for bipolar disorder and therefore received higher scores on the CBCL based on prodromal symptomatology. A longitudinal follow-up of this cohort is necessary to ascertain whether this is the case.
