Pornography is used worldwide, and 3% of individuals may experience problematic pornography use (PPU, i.e. poorly controlled use resulting in significant distress and negative consequences). Therefore, instruments gauging PPU are needed in nation-specific languages. This study aimed to validate a modified version of the Problematic Pornography Consumption Scale-6 (PPCS-6) in the Serbian language among 1413 adults (52.9% males) aged from 18 to 54 (Mage = 24.96, SD = 4.46). Exploratory factor analysis on the sample’s random half yielded a single factor explaining 43% of the total variance. Confirmatory factor analysis on the sample’s other half revealed an acceptable model fit. Internal consistency (Cronbach’s alpha) was acceptable. The scale exhibited configural and partial metric invariance across genders and convergent validity. Latent profile analysis identified that 8.1% of the participants were at risk of experiencing PPU. In comparison, this value was 9.6% based on a calculated cutoff score (≥ 19) with acceptable values (.69 and.96) of sensitivity and specificity. To conclude, the Serbian modified version of the PPCS-6 appears to be a valid and reliable scale for screening PPU.

Maternal problematic smartphone use (PSU) may unintentionally model such behaviors in children and disrupt the quality of mother–child interactions. Therefore, it is essential to examine factors that potentially contribute to PSU, such as entertainment-related smartphone use (ENT), loneliness, and mothers’ ability to tolerate their child’s distress (i.e., distress intolerance; DI). Using data from 1062 mothers of preschool-aged children, we tested whether loneliness and DI moderated the relationship between ENT and PSU. Results showed small but statistically significant moderation effects of DI (b = 0.046, p =.007) and loneliness (b = 0.083, p =.006), indicating that ENT was more strongly linked to PSU among mothers experiencing higher levels of DI and loneliness. Findings suggest that the use of smartphones for entertainment may more easily develop into PSU in mothers with elevated risk factors, such as DI and loneliness. However, given the small effect sizes and the single-item assessment of entertainment-related smartphone use, these findings should be interpreted with caution.
