Consumption of pornographic materials was examined in 3328 Secondary 1 students in Hong Kong. Results showed that over 90% of the respondents had never consumed pornographic materials in the past year. Compared to traditional pornography, internet pornography was the most common medium that participants used when viewing pornographic materials. Males reported a higher level of pornography exposure than females did. Results showed that different measures of positive youth development and family functioning were related to adolescents’ consumption of pornographic materials. In general, higher levels of positive youth development and better family functioning were related to a lower level of pornography consumption. The relative contribution of positive youth development and family factors to consumption of pornographic materials was also explored.
