Abstract：
Depressive symptoms and aggression frequently occur together, and this co-occurrence may result in more severe developmental problems. However, it is unclear if there are distinct patterns of co-occurrence. This study investigated the co-occurrence patterns of depressive symptoms and aggression, and examined their stability and demographic characteristics. A total of 1010 Chinese adolescents (50.6% girls; mean age at T1 = 12.54 years, SD = 0.42) participated in annual surveys over three years (2019-2021). Three different patterns of co-occurrence were found except for the normal group: depression-dominant co-occurrence (13.6%), aggression-dominant co-occurrence (3.2%), and moderate co-occurrence (6.0%) (T1). In these co-occurrence patterns, adolescents classified as aggression-dominant co-occurrence exhibited the most instability and frequent changes, while adolescents classified as depression-dominant co-occurrence exhibited the most stability. Boys or younger adolescents were more likely to exhibit the aggression-dominant co-occurrence, while girls or older adolescents were more likely to exhibit the depression-dominant co-occurrence. The findings indicate that the co-occurrence patterns observed are distinct and are dominated by aggression or depression, which implies the need for targeted intervention practices.
摘要：
抑郁症状和攻击性经常同时发生，这种共存可能会导致更严重的发育问题。然而,目前尚不清楚是否有不同的共现模式。这项研究调查了抑郁症状和攻击性的共同发生模式，并研究了它们的稳定性和人口特征。共有1010名中国青少年（50.6%为女孩；T1的平均年龄=12.54岁，SD=0.42）参加了三年（2019-2021年）的年度调查。除正常组外，还发现了三种不同的共现模式:抑郁-显性共现(13.6%)，侵略主导的共现(3.2%)，中度共现（6.0%）（T1）。在这些共现模式中，被归类为侵略占主导地位的青少年表现出最不稳定和最频繁的变化，而被归类为抑郁症为主的青少年表现出最大的稳定性。男孩或年轻的青少年更有可能表现出攻击性主导的共现，而女孩或年龄较大的青少年更有可能表现出抑郁症主导的并发性。研究结果表明，观察到的共同发生模式是不同的，并且以侵略或抑郁为主导，这意味着需要有针对性的干预措施。
