Important to point out that a majority of 70% were married or had a life partner. The average age of subjects was 37.The results indicated that, as hypothesized, social anxiety and internet use were positively correlated, but that internet use did not mediate the relationship between social anxiety and loneliness. The results also showed, as hypothesized, that social anxiety and pornography use were positively correlated and pornography use and loneliness were positive correlated. Finally, the results indicated that pornography use weakly mediated the relationship between social anxiety and loneliness.
