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.
