Abstract
The purpose of the present study is to provide an overview of the disorder and develop a new behavioral-cognitive-metacognitive model to explain it. The present study is a descriptive-correlational research which uses the structural equation model. In this study, at first, a comprehensive and detailed explanation of skin picking disorder is presented. Then the conceptual model is presented and finally, the model which is developed by using structural equation model is tested by Amos Graphics. The results of the structural equation model showed that the developed model in this study is able to explain skin picking disorder. Also the results of the overall fit indices for structural equation modeling show that the developed model has good fit to the sample data and is closely associated with the theoretical assumptions. Since the model presented in this study is multi-dimensional and takes into consideration all of the three behavioral, cognitive, metacognitive dimensions and these three dimensions are considered interdependent and not dependent and contradictory, it is considered as a new explanatory model. The model may prompt future researches into skin picking disorder and facilitate clinical treatments and case formulations associated with this disorder.
Highlights
Skin Picking Disorder (SPD) is a chronic problem which is characterized by excessive and recurrent manipulating and picking of the skin which is not due to dermatological conditions
SPD has been proposed as a separate diagnosis in the DSM-5 (The fifth edition of the Diagnostic and Statistical Manual for Mental Disorders) in the diagnostic category of Obsessive-Compulsive Disorder (OCD) and its associated disorders (Lochner, Grant, Odlaug, & Stein, 2012; Rabiei, Donyavi, Nikfarjam, & Mohammad Nezhady, 2015)
The main objective of the present study is to develop and validate a behavioral-cognitive-metacognitive model to explain SPD
Summary
Skin Picking Disorder (SPD) is a chronic problem which is characterized by excessive and recurrent manipulating and picking of the skin which is not due to dermatological conditions. Patients typically have desire and urge to pick their skin and it is difficult for them to control and stop these behaviors. Skin picking usually results in tissue damage and appearance deformity in these individuals (Snorrason, Belleau, & Woods, 2012). Many of these patients suffer from functional impairments and emotional distress due to external deformity and inability to control these behaviors (Odlaug et al, 2013). SPD has been proposed as a separate diagnosis in the DSM-5 (The fifth edition of the Diagnostic and Statistical Manual for Mental Disorders) in the diagnostic category of Obsessive-Compulsive Disorder (OCD) and its associated disorders (Lochner, Grant, Odlaug, & Stein, 2012; Rabiei, Donyavi, Nikfarjam, & Mohammad Nezhady, 2015)
