To examine the influences of familial, peer and individual predictors of suicidal acts in a longitudinal study with a subset of school adolescents reporting high levels of depressive symptoms.
A representative sample of Norwegian school students (N=2464, mean age 13.7 years, T1) was reassessed after 1 year (T2) with the same questionnaire. All high scorers of depressive symptoms on the Mood and Feelings Questionnaire (MFQ) at T2 were defined as cases. One control from low or middle scorers, matched for age and gender, was randomly assigned to every two cases. This subset (n=345) was diagnostically assessed by face-to-face K-SADS-PL interviews (mean age=14.9 years). The same subset was reassessed after 5 years (T3) by using the same questionnaire (n=252, mean age=20.0 years) and telephone K-SADS-PL interviews (n=242). The participation rate at T3 was 76.9% (n=265). The questionnaire explored various relationships with family members, peers and individual factors such as lifestyle habits, and physical health.
Irrespective of time, history of a suicidal act significantly predicted a later suicidal act. Not living with both biological parents and a diagnosis of any depressive disorder were significant predictors for younger and older adolescents, respectively.
In line with the findings of previous clinical studies, our results underline the importance of identifying previous suicidal acts, depressive disorders, broken homes and risk behaviours such as smoking and intoxication in the assessment of suicidal risk across adolescence.
在一项针对报告有高水平抑郁症状的部分青少年学生的纵向研究中，考察自杀行为的家庭、同伴和个体预测因素的影响。
对挪威学生的一个代表性样本（N = 2464，平均年龄13.7岁，T1）在1年后（T2）使用相同问卷进行重新评估。将T2时在情绪与情感问卷（MFQ）上抑郁症状高分者均定义为病例。每两个病例随机分配一名来自低或中度得分者、年龄和性别匹配的对照。通过面对面的K-SADS-PL访谈（平均年龄 = 14.9岁）对该子集（n = 345）进行诊断评估。5年后（T3）使用相同问卷（n = 252，平均年龄 = 20.0岁）和电话K-SADS-PL访谈（n = 242）对同一子集进行重新评估。T3时的参与率为76.9%（n = 265）。问卷探究了与家庭成员、同伴的各种关系以及生活方式习惯和身体健康等个体因素。
无论时间如何，自杀行为史均能显著预测后来的自杀行为。与亲生父母双方均不住在一起以及诊断为任何抑郁障碍分别是青少年早期和晚期的显著预测因素。
与先前临床研究结果一致，我们的结果强调了在评估整个青春期自杀风险时识别既往自杀行为、抑郁障碍、家庭破裂以及吸烟和酗酒等风险行为的重要性。
