Considering the limited effectiveness of current treatments and the need for innovative approaches, the present study aimed to evaluate the effectiveness of Paradoxical Psychotherapy like PTC model in reducing symptoms of trichotillomania. In In this single-group quasi-experimental time-series, 17 women with symptoms of trichotillomania were selected through purposive sampling. The intervention consisted of five sessions based on the PTC model, and assessments were conducted at four stages (baseline, Third session, post-treatment, and two-month follow-up) using the Massachusetts General Hospital Hairpulling Scale (MGH-HS) and the Treatment Outcome Subjective Rating Scale (TOSRS). Data were analyzed using repeated measures ANOVA and Friedman test. Findings showed that Paradoxical psychotherapy significantly reduced trichotillomania symptoms over time (η²=0.85, p&lt;0.001), with the greatest changes observed between baseline and follow-up. TOSRS results also indicated significant improvement in participants’ condition and the persistence of therapeutic effects during follow-up Paradoxical psychotherapy, by altering the individual’s relationship with the symptom, reducing performance anxiety, and strengthening ego functions, can effectively reduce trichotillomania symptoms both rapidly and sustainably. Therefore, Paradoxical psychotherapy can be recommended as a short-term and targeted intervention for trichotillomania, especially in cases resistant to direct treatment approaches.</p> https://journals.kmanpub.com/index.php/psychnexus/article/download/4607/9155
