A case study on the application of cognitive behavioral therapy in the treatment of trichotillomania

This case study explores the application of Cognitive Behavioral Therapy (CBT) in treating Trichotillomania (Hair-Pulling Disorder) in a 12-year-old adolescent female. She presented with recurrent hair-pulling behaviours resulting in significant hair loss and emotional distress, including feelings of guilt, shame, and social withdrawal. Using a comprehensive assessment approach, including the National Institute of Mental Health Trichotillomania Severity Scale (NIMH-TSS) and Impairment Scale (NIMH-TIS), her condition was initially evaluated as severe. The therapeutic intervention employed a structured CBT approach incorporating psychoeducation, Habit Reversal Training (HRT), stimulus control, and cognitive strategies to address the cognitive-behavioural cycle contributing to her hair-pulling behaviours. Following 10 therapy sessions, she demonstrated a significant improvement, with reductions in hair-pulling behavior. Post-treatment assessments revealed a marked decrease in severity, as evidenced by a reduction in NIMH-TSS and NIMH-TIS scores, as well as noticeable hair regrowth. This case highlights the efficacy of CBT, especially when combined with behavioural strategies, in treating trichotillomania and underscores the importance of family involvement and relapse prevention techniques in ensuring long-term recovery.
