Behavior Therapy and Pharmacotherapy for Trichotillomania: Choice of Treatment, Patient Acceptance, and Long-Term Outcome

Abstract

AbstractSixty-three trichotillomania (TTM) patients treated in a specialty clinic were retrospectively studied for treatment referral patterns, comparison of treatment outcomes, and long-term follow-up. Patients subjectively rated their individual treatments based on success, logicality, confidence in recommending the treatment to others, outcome expectations, and compliance. Subjects referred for combined behavior therapy (BT) and medication treatment (MT) were more depressed, more anxious, and reported greater psychosocial impairment and impact secondary to hair pulling than individuals referred for either treatment alone. Neither the Massachusetts General Hospital Hair Pulling Severity Scale (HPS) nor the Rosenberg Self-Esteem Scale (SES) scores differed between those referred for combined treatment vs those receiving monotherapy. The combination therapy patients showed a greater reduction in HPS scores than those receiving single-modality treatment and no longer differed significantly from monotherapy patients following treatment in terms of Beck Depression Inventory (BDI), Beck Anxiety Index (BAI), and Sickness Impact Profile (SIP) scores. Patients treated with both BT and MT rated BT as more successful and had greater confidence in recommending the intervention. Conversely, compliance was significantly higher for MT than BT. Other treatments, especially support groups, were rated positively. Comparison of patients currently receiving treatment with those no longer in active treatment revealed no statistically significant differences. Ten of 19 patients who were out of treatment for over 1 year rated themselves as treatment responders. Significant improvements in HPS, BDI, BAI, and SES scores were reported in the few hair pullers out of treatment more than 1 year for whom objective rating scale scores were available.
