Abstract

The purpose of this study was to examine the moderated mediating effect of mindfulness through obsessive beliefs on the relationship between incompleteness and obsessive-compulsive symptoms. A total of 555 undergraduate students completed the Obsessive-Compulsive Trait Core Domains Questionnaire (OC-TCDQ), Obsessive Beliefs Questionnaire 44 (OBQ-44), the Padua Inventory-Washington State University Revision (PI-WSUR), and the Mindfulness Scale. Data were analyzed using SPSS 23.0 and its Macro. The main findings were as follows: First, the results of bootstrapping indicated that obsessive beliefs mediated the relationship between incompleteness and obsessive-compulsive symptoms. Second, hierarchical regression and slope analyses revealed the moderating effect of mindfulness on the relationship between obsessive beliefs and obsessive compulsive symptoms. Third, mindfulness moderated the mediating effect of incompleteness on obsessive-compulsive symptoms through obsessive beliefs. Finally, the results indicated that among several factors of mindfulness, present-moment awareness, concentration, and de-centered attention influence the relationship between obsession and obsessive-compulsive disorder, which is considered useful for future therapeutic interventions.
