Clinical Trial Summary

Skin Picking Disorder (SPD) affects up to 10% of the general population, causing significant socioeconomic damage in 75% of affected individuals. It is characterized by the repeated habit of touching the skin itself, causing or aggravating wounds, with difficulty in controlling the habit. It is associated with anxiety disorders in about 20% of cases and with depressive disorder in about 50%. Patients with SPD have difficulties in regulating emotions, being more vulnerable to having their mental symptoms aggravated in face of stressful situations, such as the current coronavirus-19 pandemia. Among the treatments available to SPD, cognitive behavioral therapy is the only intervention superior to placebo, and there is still no medication approved by the FDA indicated specifically to SPD. The effectiveness of cognitive behavioral therapy was assessed in a randomized clinical trial with Brazilian patients with SPD, but its long-term benefit has not yet been evaluated. Additionally, telemedicine interventions can be effective and used during pandemia, but the effectiveness of internet delivered cognitive behavioral therapy for SPD is not clear yet.


Description:

This study is a randomized clinical trial, in which patients diagnosed with skin picking disorder (SPD) will be evaluated and, if symptomatic for the disease, will be randomized to one of the arms: intervention arm with 2 booster sessions of cognitive behavioral therapy in online format; active control arm, in which individuals will watch videos with quality of life orientation. Patients included in this study are coming from a brazilian clinical trial conducted between the years of 2014 and 2018, in wich patients with SPD were treated with a cognitive behavioral treatment protocol in individual or group formats, resulting in improvement of SPD symptoms and comorbid anxiety and depression. Before the intervention, individuals will be evaluated by a psychiatrist, to assess SPD and comorbid symptoms severity, thru the application of some instruments to assess SPD, anxiety, depression and emotional regulation. Also, the CRISIS questionnaire, about the impact of COVID-19 in mental health, will be applied. After the interventions, the instruments will be applied again, by the same evaluator, wich is blinded to the type of intervention that the patient received.
