Sexual compulsivity and its relationship with condomless sex among unmarried female migrant workers in Shanghai, China: a cross-sectional study.

Background: Individuals with high sexual compulsivity are preoccupied with their sexual desire to such an extent that it interferes with their normal daily life and can inhibit self-control. Previous studies have found a close association between sexual compulsivity and condomless sex among different populations; however, no studies have investigated this among unmarried female migrant workers in China. This study aimed to validate the Sexual Compulsivity Scale (SCS) for appropriate use and examine the association between sexual compulsivity and condomless sex in this target population.

Methods: In 2015, we recruited 1325 unmarried female migrant workers in Shanghai, China. Information about sociodemographics, sexual compulsivity, and condomless sex were collected using a structured questionnaire. Exploratory factor analysis and reliability analysis were performed to validate the Chinese version of the SCS. Multiple logistic regression analyses were used to examine the association between sexual compulsivity and condomless sex.

Results: The prevalence of condomless sex in the previous 6 months was 66.8% among all participants. The SCS was proven internally consistent for the overall scale (Cronbach's α = 0.89), and two factors, Social Disruptiveness (Cronbach's α = 0.87) and Perceived Self-Control (Cronbach's α = 0.84), were extracted. With mean total score of 18.25 (standard deviation = 4.94) after adjusting for significant sociodemographic factors, the SCS total scores (adjusted odds ratio [AOR] = 1.04, 95% confidence interval [CI] = 1.02-1.07) and two subscale scores (AOR = 1.07, 95% CI = 1.02-1.13; AOR = 1.06, 95% CI = 1.02-1.10) were all related to inconsistent condom use with partners in the previous 6 months.

Conclusions: The Chinese version of the SCS was found to be well adaptable for use among unmarried Chinese female migrant workers and a potential predictor for condomless sex. In addition to safe sex interventions, counselling on managing sexually compulsivity should also be provided in this population.
