We used Developmental Systems Theory as a framework for understanding the role of contextual factors in the development of purpose in urban adolescents. The sample included primarily low-socioeconomic students of color attending urban middle schools (n = 2,629; 10-16 years of age). Longitudinal data were collected at four time points across two years. We used hierarchical linear modeling to model change in purpose. On average, purpose declined over time. We also identified several predictors of intercept and slope. For example, Black youth had a higher average purpose intercept, as well as a steeper average decline than other racial/ethnic groups. Females demonstrated a higher average purpose intercept than males, but this effect disappeared when academic achievement was added to the model.
我们使用发展系统理论作为理解背景因素在城市青少年目标发展中的作用的框架。该样本主要包括就读于城市中学的低社会经济地位的有色人种学生（n=2629；10-16 岁）。在两年的四个时间点上收集了纵向数据。我们使用分层线性模型来对目标的变化进行建模。平均而言，目标随着时间的推移而下降。我们还确定了几个截距和斜率的预测因子。例如，黑人青少年的平均目标截距较高，平均下降幅度也比其他种族/族裔群体大。女性的平均目标截距高于男性，但当将学业成绩纳入模型时，这种影响就消失了。
