          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.


          【摘要】 目的 通过全球小年龄研究 (GEAS)上海研究点纵向调査数据分析冲动性特质对青少年观看色情片的影响, 为 青少年性健康促进提供依据。 方法 采用分层整群抽样方法选取上海市某区 3 所初中六至八年级 1 512 名学生, 从 2017—2020 年进行 3 轮纵向数据收集。基线和随访的色情片观看情况及社会人口学相关信息由学生在平板电脑上自填。 冲动性特质测量仅在 2018 年随访时通过 Barratt 冲动性量表纸质问卷获取。采用一般统计学描述、面板数据描述和混合线 性模型进行分析。 结果 3 次调査中, 32.7% 的青少年 (494 名) 有过看色情片的经历。男生的运动性冲动得分髙于女生 (16.33±3.25, 15.66±2.93), 差异有统计学意义 ( t = 4.13, P<0.01), 无计划性冲动得分低于女生 (22.83±5.21, 23.65±5.11), 差 异有统计学意义 ( t = −3.03, P<0.01)。混合效应线性模型结果显示, 冲动性总得分与色情片观看关联有统计学意义 ( β =0.001, P<0.01); 冲动性各亚组分析中, 髙运动性冲动及髙注意性冲动显著影响色情片观看 ( P 值均<0.01); 女生、父母较多 了解及学校有人关心的青少年较少观看色情片, 而使用网络时间 >3 h/d 的青少年观看色情片的频率更髙 ( P 值均<0.01)。 结论 青少年观看色情片与冲动性特质具有稳定的关联。应针对这一年龄青少年进行合理疏导, 使之具有在良莠不齐的 媒体世界中明辨是非的能力。
