Associations between adolescents watching pornography and poor mental health in three Swedish surveys

The aim of this study was to examine the association between watching pornography and poor mental health in three repeated cross-sectional surveys in Sweden (2004, 2009, 2014) among high school seniors (13,277 students) with an average age of 18 years. The same index questions concerning ever having watched pornography and the frequency of watching pornography during the last year were combined with three different measures of psychological health and background control variables in multiple logistic regression and forward stepwise logistic regression models. The repeated cross-sectional surveys did not find any consistent associations across years between poor mental health and ever having watched pornography or the frequency of watching pornography. Having watched deviant pornography (containing violence, children and/or animals) was associated with poor mental health among boys in two surveys but only in one survey among girls. Other characteristics, such as mother's unemployment (especially boys), parenting style (especially high controlling parents among boys) and experiences of sexual abuse (especially penetrating abuse among girls), were more consistently and strongly associated to poor mental health across the three surveys. This study stresses the importance of controlling for multiple background variables when studying the association between watching pornography and mental health, since the association might primarily be explained by underlying confounding variables.

Adolescents' Use of Pornography: Trends over a Ten-year Period in Sweden

Using survey data from three nationally representative surveys in 2004, 2009, and 2014 among senior high school students in Sweden, this study investigates trends in adolescents' lifetime prevalence of pornography use, frequency of pornography use, and type of pornography used over time. While almost all boys and a considerable proportion of girls used pornography across the three waves, the lifetime prevalence of pornography use decreased overall for both girls and boys. The share of boys who use pornography frequently increased over the three survey cycles; those who reported using pornography daily increased from 11% in 2004 to 24% in 2014. In contrast, there was no change in girls who reported using pornography daily, while the proportion who never used pornography increased from 40% in 2004 to 51% in 2014. Adolescents appear to use a narrower range of different pornography types over the survey cycles. Multiple logistic regression models were generated to investigate factors associated with pornography use over the 10-year period. The results suggest that rule-breaking behavior, having higher economic status and higher academic achievement were related to boy's pornography use, while rule-breaking behavior, early sexual debut and victimization were associated with girls' pornography use.
