Purity Culture Beliefs, Partner Evaluation, and Sexual Reputation Concerns in Committed Relationship Contexts: Correlational Evidence from a Chinese Online Sample

This study aims to explore the associations and predictive effects of purity culture beliefs on committed relationship attitudes. Through a survey of 449 Chinese online participants (M=29.50, SD=7.48), significant correlations were found between the total score of the Purity Culture Beliefs Scale (PCBS) and 3 items about committed relationship attitudes in real-life contexts: specifically, a significant negative correlation with Other Did (ρ=-0.523, p<0.001), a significant positive correlation with Self Did (ρ=0.485, p<0.001), and a weak positive correlation with Self Undone (ρ=0.220, p<0.001). Based on these correlational results, further regression analysis was conducted, controlling for demographic variables. The results showed that PCBS positively predicted Self Did and SelfUndone, and negatively predicted Other Did, with standardized coefficients β of 0.484, 0.196, and -0.522 (all p<0.001), respectively. Among these, the effects on Other Did and Self Did were moderate, while the effect on Self Undone was weak. In addition, demographic analysis revealed significant differences in the PCBS total score, its subscales, and the items about relationship attitudes across variables such as gender, education, and income. This study helps reveal the association mechanism between purity culture beliefs, romantic evaluation, and sexual reputation concerns, providing a reference for further research in related fields.
