A meta-analysis of the published research on the effects of pornography
(from the chapter) A meta-analysis of 46 published studies was undertaken to determine the effects of pornography on sexual deviancy, sexual perpetration, attitudes regarding intimate relationships, and attitudes regarding the rape myth. Most of the studies were done in the US (39; 85%) and ranged in date from 1962 to 1995, with 16 (35%) published between 1990 and 1995, and 15 (33%) between 1978 and 1983. A total sample size of 12,323 people comprised the present meta-analysis. Effect sizes were computed on each of the dependent variables for studies which were published in an academic journal, had a total sample size of 12 or greater, and included a contrast or comparison group. Average unweighted and weighted effect sizes for sexual deviancy (.68 and .65), sexual perpetration (.67 and .46), intimate relationships (.83 and .40), and the rape myth (.74 and .64) provide evidence confirming the link between increased risk for negative development when exposed to pornography. These results suggest that the research in this area can move beyond the question of whether pornography has an influence on violence and family functioning. Various potentially moderating variables were assessed for each of the studies. (PsycINFO Database Record (c) 2005 APA, all rights reserved).
