This study investigated associations among sexual self-schemas, attachment-related anxiety and avoidance in close relationships, and sexual compulsivity among young adults. The main study variables were sexual self-schemas, attachment dimensions, and sexual compulsivity, with particular attention to relationships among their respective subscales. A correlational survey design was employed. Data were initially collected from 503 participants; responses from 20 individuals were subsequently excluded following outlier screening, resulting in a final analytical sample of 483 participants. The Sexual Self-Schema Scale (SSSS), Experiences in Close Relationships Scale–Revised (ECR-II), and Sexual Compulsivity Scale (SCS) were administered as data collection instruments. Analyses were conducted using SPSS version 29. After evaluating the distributions of the scale scores, Pearson correlation analyses and multiple linear regression analysis were performed. Results indicated negative associations between sexual self-schema scores and attachment-related anxiety and avoidance, as well as small positive associations between sexual self-schema scores and sexual compulsivity. Attachment-related anxiety was positively related to sexual compulsivity, whereas avoidance was not significantly related to the SCS outcomes. In particular, the sensual/stimulating dimension of the SSSS and the anxiety dimension of the ECR-II were significant positive predictors of total SCS scores in the multiple regression model. Together, these two dimensions accounted for approximately 11.2% of the variance in sexual compulsivity scores (adjusted R\(^2\) = .108). The findings describe statistical associations within a cross-sectional sample and do not establish causal relationships.
