Whether pornography consumption is a reliable correlate of sexually aggressive behavior continues to be debated. Meta-analyses of experimental studies have found effects on aggressive behavior and attitudes. That pornography consumption correlates with aggressive attitudes in naturalistic studies has also been found. Yet, no meta-analysis has addressed the question motivating this body of work: Is pornography consumption correlated with committing actual acts of sexual aggression? 22 studies from 7 different countries were analyzed. Consumption was associated with sexual aggression in the United States and internationally, among males and females, and in cross-sectional and longitudinal studies. Associations were stronger for verbal than physical sexual aggression, although both were significant. The general pattern of results suggested that violent content may be an exacerbating factor.

A classic question in the communication literature is whether pornography consumption affects consumers' satisfaction. The present paper represents the first attempt to address this question via meta‐analysis. Fifty studies collectively including more than 50,000 participants from 10 countries were located across the interpersonal domains of sexual and relational satisfaction and the intrapersonal domains of body and self satisfaction. Pornography consumption was not related to the intrapersonal satisfaction outcomes that were studied. However, pornography consumption was associated with lower interpersonal satisfaction outcomes in cross‐sectional surveys, longitudinal surveys, and experiments. Associations between pornography consumption and reduced interpersonal satisfaction outcomes were not moderated by their year of release or their publication status. But analyses by sex indicted significant results for men only.

This article reports tests of the relationships between problematic Internet use (PIU), time spent using the Internet, and psychosocial problems from the two perspectives. Ten individual meta-analyses were first conducted to identify weighted mean correlations among the five variables included within the models. The correlations derived from the meta-analyses were subsequently used in path analysis to test the alternative characterizations. The results offer some support for the deficient self-regulation model but provide relatively little evidence consistent with the pathology perspective of PIU.
