Abstract

This study examined the role of worry and rumination, both forms of perseverative cognition, as parallel mediators in the relationship between socially prescribed perfectionism and somatization symptoms. A total of 545 adults completed online self-report questionnaires assessing socially prescribed perfectionism, worry, rumination, and somatization symptoms. The results showed a positive association between socially prescribed perfectionism and both worry and rumination, as well as an increase in somatization symptoms. Additionally, the relationship between socially prescribed perfectionism and somatization symptoms was fully mediated in parallel by worry and rumination. These findings indicate that individuals with high socially prescribed perfectionism, which involves a strong desire to meet others' expectations or external standards, tend to experience more worry and engage in rumination more frequently. Consequently, these patterns of perseverative cognition are linked to increased somatization symptoms, such as headaches, fatigue, and sleep difficulties. The results highlight the significance of addressing perseverative cognition in interventions for somatization among those with high levels of socially prescribed perfectionism. The study also discusses its implications and limitations.
