Adolescence is a high-risk period for the onset of suicidal thoughts and behaviors. Identification of preceding patterns of internalizing and externalizing symptoms that are associated with subsequent suicidal thoughts may offer a better understanding of how to prevent adolescent suicide.
Data from the National Longitudinal Survey of Children and Youth, a prospective population-based Canadian cohort, contained Child Behavior Checklist items which were used to examine profiles and transitions of internalizing and externalizing symptoms in children, aged 6-11 years (n = 8266). The association between these profiles/transitions and suicidal thoughts in adolescents was examined using multivariate logistic regression modeling.
Latent profile analyses identified four measurement invariant profiles of internalizing and externalizing symptoms at ages 6/7 and 10/11: (1) low on all symptoms, (2) moderate on all symptoms, (3) high on all symptoms, and (4) high on hyperactivity/inattention and internalizing. Recurrent (homotypic or heterotypic) and increasing symptoms from 6/7 to 10/11 were associated with suicidal thoughts in adolescence, compared to those with stable low symptoms. Those with decreasing symptoms from 6/7 to 10/11 were not at increased risk of suicidal thought in adolescence.
While patterns of recurrent symptoms were associated with suicidal thoughts, a similar association was observed between profiles at age 10/11 years and suicidal thoughts. This suggests that the recent assessments of mental health symptoms in children may be as sufficient a predictor of adolescent suicidal thought as transition profiles.
青春期是出现自杀念头和行为的高风险期。识别与随后自杀念头相关的内在和外在症状的先前模式,可能有助于更好地了解如何预防青少年自杀。
加拿大全国儿童纵向研究的数据是一个前瞻性的基于人群的加拿大队列,其中包含儿童行为检查表项目,用于检查 6-11 岁儿童内在和外在症状的特征和转变(n=8266)。使用多变量逻辑回归模型来检查这些特征/转变与青少年自杀念头之间的关系。
潜在剖面分析确定了 6/7 岁和 10/11 岁时内在和外在症状的四个不变的特征:(1)所有症状均低,(2)所有症状均中,(3)所有症状均高,以及(4)多动/注意力不集中和内在症状高。与稳定的低症状相比,6/7 岁至 10/11 岁期间反复发作(同型或异型)和症状增加与青少年时期的自杀念头有关。与症状从 6/7 岁至 10/11 岁下降的人相比,自杀念头的风险并未增加。
虽然反复发作的症状模式与自杀念头有关,但在 10/11 岁时的特征与自杀念头之间也观察到了类似的关联。这表明儿童心理健康症状的近期评估可能与过渡特征一样,足以预测青少年自杀念头。
