Bipolar Disorder

Abstract This chapter details the section on Bipolar Disorder in the Anxiety and Related Disorders Interview Schedule for DSM-5, Child Version: Parent Interview Schedule (PIS). The interview should ensure that the child's elevated mood or irritability is not accounted for by other disorders such as Oppositional Defiant Disorder (ODD), attention deficit hyperactivity disorder (ADHD), or substance use disorder. If the parent endorsed a Major Depressive Episode, the interviewer should inquire whether these symptoms occurred during the same 2-week period. If criteria are met for a Manic or Hypomanic Episode, the interviewer should consider a diagnosis of Bipolar Disorder. If the child's symptoms do not meet the full criteria for a Manic or Hypomanic Episode, the interviewer should consider a diagnosis of Bipolar Disorder, NOS. These children may have typical bipolar symptoms but not the DSM-5 required duration. In addition, these children may be characterized by severe irritability, aggressiveness, agitation, and/or mood lability. There may also be more rapid cycling of mood.
