Developmental epidemiological work shows that rates of depression as assessed by diagnostic interviews increase from childhood through early adulthood. It could be assumed that the trajectory of depression as assessed by self-report questionnaire measures would be characterized by a similar pattern. We aimed to evaluate this assumption and more clearly establish the longitudinal trajectory of depression in youth, when repeatedly assessed over time with a self-report questionnaire and with a diagnostic interview. Participants were 679 youth ages 7-16 years at baseline (Mage = 11.8, SD = 2.4, 56% girls). They completed the Children's Depression Inventory (CDI) every 3 months for 3 years (13 time points) and were interviewed every 6 months using the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS) to ascertain onset of depression diagnosis. A series of growth curve models was fit to the CDI and K-SADS data. A piecewise model characterized growth in depression as assessed by the CDI, with an initial negative linear slope (b = -0.64) spanning the first 3 assessments, and a positive quadratic second slope (b = 0.015; linear component: b = -0.22) spanning the remaining 10 assessments. Depression, as assessed by the K-SADS, grew continuously over time (a positive linear slope, b = 0.23). Findings illustrate differences between longitudinal trajectories of depression when assessed repeatedly by self-report questionnaire and diagnostic interview. Implications for research designed to study longitudinal depression trajectories are discussed. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

青年人在不同时间反复评估抑郁的纵向模式：自我报告问卷和诊断性访谈中的轨迹不同。

发展性流行病学研究表明，根据诊断性访谈评估的抑郁症患病率从儿童期到成年早期都有所增加。可以假设，通过自我报告调查表测评的抑郁轨迹将具有相似的特征。当通过自我报告调查表和诊断性访谈随时间反复评估时，我们旨在评估该假设并更清楚地确定青年人抑郁症的纵向轨迹。基线时参与者为679位7-16岁的青年（法师= 11.8，SD = 2.4，56％的女孩）。他们完成了儿童 连续3年（13个时间点）每隔3个月进行一次抑郁量调查（CDI），并每6个月使用儿童情感障碍和精神分裂症患儿时间表（K-SADS）进行访谈，以确定抑郁症的诊断开始时间。一系列的增长曲线模型适合CDI和K-SADS数据。通过CDI评估的抑郁症的分段模型，其初始的线性负斜率（b = -0.64）跨越前3次评估，并且二次方的正斜率（b = 0.015；线性分量：b = -0.22）涵盖其余的10个评估。通过K-SADS评估，抑郁症随时间持续增长（线性斜率为正，b = 0.23）。研究结果表明，通过自我报告调查表和诊断性访谈反复评估抑郁症的纵向轨迹之间的差异。讨论了对研究纵向longitudinal回轨迹的研究的意义。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
