Background Subculture is a unique cultural group formed outside the mainstream culture, and emerging niche clothing culture usually refers to some non-traditional, independent brand or style clothing culture. Compulsive personality disorder is a psychological disorder in which patients tend to overly focus on details, order, and perfectionism. For young people with obsessive-compulsive personality disorder, participating in emerging niche clothing culture may have some psychological effects.Subjects and MethodsSelect 100 patients with obsessive-compulsive personality disorder and randomly divide them into two groups: the experimental group and the control group. The experimental group of patients adopted emerging niche clothing culture and conventional psychological treatment methods, while the control group adopted conventional psychological treatment methods. The experimental period is 3 months, and the treatment effects of patients after 3 months are compared and statistically analyzed using Excel and SPSS23.0.ResultsThe research results indicate that the combination of emerging niche clothing culture and conventional psychotherapy methods is more likely to obtain a different way of relaxation and decompression compared to conventional psychotherapy methods. This novel rather than traditional clothing style can become a way for them to alleviate the pressure of compulsive thinking and behavior, providing physical and mental comfort.ConclusionsThe emerging niche clothing culture can provide a unique way for young people with obsessive-compulsive personality disorders to express their individuality and uniqueness. By choosing clothing and styles that are different from mainstream clothing styles, they can express their independent thinking and aesthetic preferences.Acknowledgement2021 National Social Science Foundation Art Program (No.21BG103).
