Combining Cognitive Behavioral Therapy and Therapeutic Lifestyle Change for Persistent Depressive Disorder
Monaghan, Kiley E.
The following is a de-identified case study that presents the assessment, diagnosis, and treatment of Persistent Depressive Disorder (PDD) utilizing interventions derived from Cognitive Behavioral Therapy (CBT; Beck, 1963) and Therapeutic Lifestyle Change (TLC; Ilardi, 2010). For the purpose of protecting the client’s anonymity, names and other identifying information have been changed. The name “John” is used to refer to the client within this document. When presenting for treatment, John, a 21-year-old Caucasian transgender male, was struggling to manage symptoms of depression. John was assessed with the Diagnostic Interview for Anxiety, Mood, and Obsessive-Compulsive and Related Neuropsychiatric Disorders (DIAMOND; Tolin et al., 2018), the Beck Depression Inventory-II (BDI-II; Beck et al., 1996), and a battery of self-report assessments. Over the course of six months, John attended 20 CBT/TLC treatment sessions. Psychoeducation, cognitive restructuring practice, self-monitoring, and behavioral activation strategies (including TLC) were utilized throughout the course of treatment. Following treatment, John was successfully managing symptoms of depression, and his scores on the Beck Depression Inventory-II had decreased substantially.
