单类内隐联想测验评估自杀意念的有效性初探

摘要

Objective To investigate the effects of single category implicit association test(SC-IAT) to evaluate suicide ideation in young patients with depression and anxiety.Methods A total of 169 young patients with depression and anxiety were assessed with Beck Scale for Suicide Ideation (BSI),SC-IAT and divided into suicide ideation group,suicide plan group and control group and there were 28 patients in each group randomly.Results There were 40.24％ for the rate of explicit suicide ideation,25.44％ for the rate of implicit suicide ideation and 16.57％ for the rate of suicide plan in all subjects.The rates of suicide plan were 41.18％ for participants possessing explicit suicide ideation,41.86％ for participants possessing implicit suicide ideation and 52.94％ for participants possessing mixed suicide ideation.There was middle level for the consistency between two measurement tools(Kappa =0.44,P ＜ 0.01).The average values of D in suicide plan group and suicide ideation group were all significantly more than 0(P ＜ 0.01,P ＜ 0.05) and the average value of D in control group was significantly less than 0 (P ＜ 0.01).There were all significant differences for the average values of D among three groups (P ＜ 0.05).Conclusion It's effective for SC-IAT to evaluate clinical suicide ideation,which should be imperative supplement for explicit measurement.%目的 探究单类内隐联想测验(SC-IAT)评估抑郁或/和焦虑状态青年患者自杀意念的有效性.方法 选取169名抑郁和/或焦虑状态青年患者进行贝克自杀意念量表(BSI)和SC-IAT测试并评估是否有自杀计划,据此随机抽取被试进行分组,自杀意念组、自杀计划组和对照组各有28名.结果 全体被试中,外显自杀意念、内隐自杀意念和自杀计划的报告率分别为40.24％、25.44％和16.57％.外显自杀意念者、内隐自杀意念者和混合自杀意念者中,自杀计划报告率分别为41.18％、41.86％和52.94％.外显、内隐测量结果有中等一致性(Kappa值=0.44,P＜0.01).单样本t检验发现,自杀计划组、自杀意念组D值均值大于0(P＜0.01,P＜0.05),对照组D值均值小于0(P＜0.01).方差分析表明组间D值差异有统计学意义(P＜0.05).Turkey事后检验显示,两两比较D值差异均有统计学意义(P＜0.05).结论 SC-IAT可以初步用于临床自杀意念的评估,是外显评估工具的重要补充.
