The goal of the present study was to evaluate the psychometric properties of the Suicide Screening Questionnaire-Self-Rating (SSQ-SR). A 25-item SSQ-SR is a newly developed suicide screening tool that measures suicide risk factors, including a history of suicidal thoughts and behaviors (STBs), life stress, and mental health problems. To investigate the reliability and validity of the SSQ-SR, we conducted a longitudinal case-control study with adults with and without STBs in the past six months. A total of 176 participants were recruited through 12 hospital-based Crisis Response Centers across South Korea. At the baseline, we administered the SSQ-SR, the Beck Scale for Suicide Ideation (BSSI), and the Patient Health Questionnaire-9 (PHQ-9). In a 6-months follow-up, we investigated whether the participants engaged in suicidal ideation, plan, or attempt since the baseline assessment. As a result, the SSQ-SR demonstrated a strong internal consistency (Cronbach's alpha coefficient = 0.96). In addition, the total score of SSQ-SR had concurrent validity compared to the total scores of the BSSI and the PHQ-9. In comparing the suicidal groups with the control group, the ROC analysis indicated the optimal cut point at 31 with a sensitivity rate of 0.97 and a specificity rate of 0.98. Through explanatory factor analysis, two factors were identified: Mental Health and Environmental Factors and Active Suicidal Thoughts and Behaviors. The SSQ-SR total and sub-factor scores were prospectively associated with subsequent suicidal ideation, plan, and attempt. These findings support that the SSQ-SR is a promising tool in prospectively screening those who are at risk of suicidal thoughts, plans, and nonfatal attempts.
本研究旨在评估自杀筛查问卷自评版（SSQ-SR）的心理测量特性。SSQ-SR 是一种新开发的自杀筛查工具，可测量自杀风险因素，包括自杀念头和行为史、生活压力和心理健康问题。为了调查 SSQ-SR 的信度和效度，我们进行了一项纵向病例对照研究，纳入了过去六个月内有和无自杀念头和行为史的成年人。共有 176 名参与者通过韩国 12 家医院危机反应中心招募。在基线时，我们使用 SSQ-SR、贝克自杀意念量表（BSSI）和患者健康问卷-9（PHQ-9）对参与者进行评估。在 6 个月的随访中，我们调查了参与者在基线评估后是否有自杀意念、计划或尝试。结果显示，SSQ-SR 具有很强的内部一致性（Cronbach's alpha 系数为 0.96）。此外，SSQ-SR 的总分与 BSSI 和 PHQ-9 的总分具有同时效度。在将自杀组与对照组进行比较时，ROC 分析表明 31 分是最佳截断点，其敏感性为 0.97，特异性为 0.98。通过解释性因素分析，确定了两个因子：心理健康和环境因素以及主动自杀念头和行为。SSQ-SR 的总分和分项得分与随后的自杀意念、计划和尝试具有前瞻性关联。这些发现支持 SSQ-SR 是一种有前途的工具，可用于前瞻性筛查有自杀念头、计划和非致命性尝试风险的人群。
