Abstract
Trichotillomania and excoriation disorder are mental health conditions in which patients habitually pull out their
hair or pick and scratch their skin. The preferred treatment, cognitive behavioural therapy with self-control
procedures, has shown strong short-term effectiveness. However, relapse is frequently reported after successful
treatment. The present study investigated whether self-control cognitions and motivation for treatment were
predictors for treatment outcome and at follow-ups in trichotillomania and excoriation disorder. To measure
treatment outcome and relapse, questionnaires were administered prior to treatment, directly after treatment, and
at three- and six-months follow-ups. The predictor self-control cognitions was measured prior to treatment,
directly after treatment, and at three- and six-months follow-ups. Motivation for treatment was measured
immediately after the first treatment session. The results showed strong treatment effects and slight relapse at
follow-up measurements. Self-control cognitions were significantly positively associated with symptom severity
at both the pre-assessment and post-assessment but were not observed to make a significant contribution to
predicting relapse. Motivation for treatment showed no association and was not examined to be a predictor for
symptom severity overtime. Limitations and recommendations were discussed.
