Abstract
Pornography consumption is a habit as ancient and controversial as it is common, especially among men. Problematic Pornography Use (PPU), defined as a type of behavioral addiction linked to the avoidance of dysphoric affect, has not been studied in our context. Therefore, the purpose of this study is to analyze the psychometric properties of the PPUS (Kor et al., 2014) in a sample of 296 adults from Lima (M=27.5, DE=11.38), in order to have a valid measure of the construct. By using factorial analysis, Oblimin rotation and principal axis extraction, we obtained 3 dimensions instead of the 4 factor structure proposed by its authors. Nonetheless, the psychometric properties of the scale as well as its internal consistency (α=.89) were adequate. Convergent validity was assessed with the BPS -Brief Pornography Screener- (r=.78); discriminant validity with an Internet Addiction Scale (r=.34) and all scales and subscales of the Mental Health Inventory MHI-P. Construct validity was assessed with sociodemographic indicators of Frequency and Amount of Consumption. We also confirmed the hypothesized associations between PPUS score and gender, age and relationship status, although not with religiosity. After that, we aimed to test gender differences regarding several aspects of their relation with pornography, such as expectations, influence, attitude and age of first access. Medians by gender of the whole sample (n=358) were compared and significant differences were found in all variables, with effect sizes ranging from small to moderate.
