Interpersonal Psychotherapy and Cognitive-Behavioral Therapy as an Integrated Treatment Approach for Co-Occurring Bipolar I and Social Anxiety Disorder

Social anxiety disorder (SAD) is frequently comorbid with bipolar disorder (BD), yet frontline pharmacological interventions for SAD are often contraindicated for individuals with BD. We present a case report of a 29-year-old male with Bipolar I Disorder who received cognitive-behavioral therapy (CBT) for SAD, followed by CBT and interpersonal therapy (IPT) for SAD. The patient completed standardized self-report measures of social anxiety and depressive symptoms throughout treatment and at 1-month and 3-month follow-ups. The greatest social anxiety symptom improvement occurred during the CBT phase, and the patient experienced small but additional benefit with the incorporation of IPT techniques. Although not a direct target of treatment, the patient’s depressive symptoms remained subthreshold throughout treatment. Finally, the patient reported significantly higher quality of life at 1-month and 3-month follow-ups, compared with a reference group of BD outpatients. Findings offer preliminary support for the integration of CBT and IPT in treating comorbid SAD among individuals with BD. Clinical implications and suggestions for future research are discussed.
