ABSTRACT

Identity development has been linked to substance use, but the directionality of this relationship remains unclear. We examined the longitudinal associations of educational and relational identity with substance use across three annual waves in 360 Dutch adolescents (M_age = 13.7 years). We found three latent profiles using the identity dimensions of commitment, exploration, and reconsideration as indicators. Using classification probabilities to determine participants’ clusters at each time point, we distinguished stable, progressive, and regressive identity transition groups. No longitudinal associations were found between identity status transitions and substance use in either direction, but we did find significant cross-sectional correlations. Therefore, our findings do not support a directional process, but hint at a spectrum/continuity or common cause model.

摘要

身份发展与物质使用有关，但这种关系的方向性仍不清楚。我们在 360 名荷兰青少年（M_年龄 = 13.7 年）。我们使用承诺、探索和重新考虑的身份维度作为指标，发现了三个潜在的配置文件。使用分类概率来确定参与者在每个时间点的集群，我们区分了稳定的、渐进的和回归的身份转换组。在任何一个方向上都没有发现身份状态转换和物质使用之间存在纵向关联，但我们确实发现了显着的横截面相关性。因此，我们的发现不支持定向过程，但暗示了频谱/连续性或共同原因模型。
