青少年早期冲动性的发展轨迹:界定亚群组及其影响因素

以发展的整体互动论和生态系统理论为基础,考察青少年早期冲动性的发展轨迹及其影响因素。采用Barratt冲动性量表、家庭环境量表、青少年感知校园氛围问卷对天津市某中学210名初中生进行了为期1年的3次追踪调查,使用潜变量增长模型、潜类别增长模型、多元Logistic回归进行数据分析。结果发现:(1)青少年早期冲动性的发展呈线性增长趋势,并可分为三个亚群组:恒低组(16.67%)、恒高组(41.43%)和居中升高组(41.91%);(2)家庭环境亲密度和教师支持对亚群组有显著预测作用。本研究揭示了在青少年早期冲动性的动态变化性、个体差异性及其相关影响因素。

The Trajectories of Impulsivity during Early Adolescence: Identifying Latent Subgroups and Influence Factors

Based on the model of person-environment transaction to investigated the developmental trajectories and its influence factors of impulsivity traits in adolescence. 210 adolescents were recruited from one junior high school in Tianjin, China. They completed the Barratt Impulsiveness Scale (BIS), Family Environment Scale (FES), and the Perceived School Climate Scale (PSCS) for three times in one year. Latent growth models, latent class growth analysis, and logistic regression were used to analysis the data. The results were as followed: (1) the impulsivity traits showed a linear growth trend during early adolescence, and there were three subgroups with different starting levels and varying rates of change: consistently high group, consistently low group, and increasing group; (2) intimacy of family environment and teachers’ support had significant predictive effect to the subgroups. In general, the dynamic changes, individual differences and influence factors of impulsivity were revealed in early adolescence in this study.
