早期青少年自伤、消极情绪与自杀意念的动态发展关系

Longitudinal Relations between Non-suicidal Self-injury,Negative Emotion,and Suicide Ideation among Early Adolescents

为探讨早期青少年自伤、消极情绪与自杀意念间的动态发展关系,研究采用随机截距交叉滞后分析对1105名七年级学生进行三次追踪调查。结果显示:在个体间水平上,早期青少年自伤与自杀意念显著正相关,消极情绪与自杀意念间显著正相关,自伤与消极情绪之间相关不显著。个体内水平上,早期青少年自伤与自杀意念发展在相邻时间点相对稳定;前期青少年消极情绪稳定性较差,后期稳定性增加;消极情绪是早期青少年产生自杀意念的风险因素且进一步导致后续的消极情绪水平升高;自杀意念是早期青少年自伤的风险因素且进一步导致后续的消极情绪和自杀意念水平升高。

The current study aimed to explore the longitudinal relations between non-suicidal self-injury,negative emotion,and suicide ideation over time by applying the random intercept cross-lagged panel model to disentangle between-and within-person associations.A total of 1105 seventh graders were recruited to complete the self-report questionnaire of the level of non-suicidal self-injury,negative emotion,and suicide ideation.The results showed that:(1)At the between-person level,suicide ideation was significantly correlated to non-suicidal self-injury and negative emotion;non-suicidal self-injury and negative emotion showed a positive but non-significant association;(2)At the within-person level,the auto-regressive paths of non-suicidal self-injury and suicide ideation across time were significant;the auto-regressive path from T1 to T2 negative emotion was non-significant,but the auto-regressive path from T2 to T3 negative emotion was significant;(3)At the within-person level,T1 negative emotion significantly predicted T2 suicide ideation,and T2 suicide ideation significantly predicted T3 negative emotion;(4)At the within-person level,T1 suicide ideation significantly predicted T2 non-suicidal self-injury,and T2 non-suicidal self-injury significantly predicted T3 negative emotion and T3 suicide ideation.
