In the present work, we evaluated reciprocal, within-dyads associations between parents’ and adolescents’ depressive symptoms across two independent samples (N = 327 and N = 435 dyads; approximately 85% biological mothers) assessed every 3 months for 2 years (Study 1) to 3 years (Study 2). Results of random intercept cross-lagged panel models converged to support positive contemporaneous patterns of cofluctuation in parental and adolescent depression such that within-persons deviations in parental depression were associated with same-direction within-persons deviations in adolescent depression at the same time point. In contrast, within-persons fluctuations in parental depression did not prospectively predict within-persons fluctuations in adolescent depression, or vice versa, across the follow-up period. Results held across boys and girls, as well as dyads with and without a parental history of depressive disorder. Overall, findings advance knowledge by demonstrating that after accounting for between-persons/dyads variance, parental and adolescent depression demonstrate contemporaneous cofluctuations but do not demonstrate within-dyads reciprocity over time.

在目前的工作中，我们评估了两个独立样本（ N = 327 和N = 435 对；大约 85% 的亲生母亲）中父母和青少年抑郁症状之间的相互、二元内关联，每 3 个月评估一次，持续 2 年（研究1) 至 3 年（研究 2）。随机截距交叉滞后面板模型的结果趋于一致，支持父母和青少年抑郁症的同时波动模式，即同一时间点父母抑郁症的人内偏差与青少年抑郁症的同向人内偏差相关。相比之下，在整个随访期间，父母抑郁症的人内波动并不能前瞻性地预测青少年抑郁症的人内波动，反之亦然。结果适用于男孩和女孩，以及有或没有抑郁症父母史的二人组。总体而言，研究结果通过证明在考虑了人/二人之间的差异后，父母和青少年抑郁症表现出同时期的共波动，但随着时间的推移并没有表现出二人内部的互惠性，从而推进了知识的发展。
