Influence of impulsivity on adolescents pornography use / 中国学校卫生

ABSTRACT

Objective@#To explore the influence of impulsive traits of adolescent on pornography use through the analysis of the Global Early Adolescent Study(GEAS) longitudinal survey data collected in Shanghai, and to provide evidence for adolescent sexual health promotion.@*Methods@#Totally 1 512 students from grades 6 to 8 in three middle schools in a district of Shanghai were selected for the present study by stratified cluster sampling method. Baseline and two-wave follow-up investigation were conducted between 2017 and 2020. Three waves of pornography use and social demographic information were collected using electronic questionnaire through tablets while impulsivity were tested only once during the follow-up in 2018 using the paper and pencil based Barratt Impulsivity Scale, version11 (BIS-11). General statistical description and panel data statistical description, as well as multilevel mixed effect linear model were used to do the analysis.@*Results@#About 32.7% (494) of the adolescents reported the experience of watching pornography in threewave analysis. Boys were more impulsive than girls in the motor subscale (16.33±3.25, 15.66±2.93, t=4.13, P<0.01) while girls were more impulsive than boys in the nonplanning subscale (23.65±5.11, 22.83±5.21, t=-3.03, P<0.01). Mixed effect linear model result showed that impulsivity was correlated with pornography use(β=0.001, P<0.01); higher impulsivity in motor and attention were correlated with more frequent pornography use(P<0.01). Being female, perceived more parental awareness and perceived care from school adults would decrease the use of pornography while spent more than 3 hours on internet would increase the use of pornography (P<0.01).@*Conclusion@#There are stable correlations between impulsivity and pornography use. It is urgent to equip young adolescents with the necessary ability to distinguish the good from the bad in the mass and internet media world.
