Abstract

Background: The Suicidal Intrusions Attributes Scale (SINAS) is a brief self-report measure designed to assess the frequency, distress, and controllability of suicidal intrusions-vivid, uncontrollable mental images and thoughts related to suicide or its aftermath. Despite its clinical relevance, its psychometric properties remain underexplored. This study aimed to evaluate the psychometric properties of the Persian version of the SINAS.

Methods: A cross-sectional design was employed. 304 outpatients (aged 18 to 65, M = 27.27, SD = 8.53) including 243 males and 61 females with a history of suicide attempts were recruited using a convenience sampling method from psychiatric clinics and hospitals in Tehran. Participants completed the SINAS along with the Beck Depression Inventory-II (BDI-II) to assess depressive symptoms, the Beck Hopelessness Scale (BHS) to measure negative expectations about the future, the Beck Scale for Suicide Ideation (BSSI) to evaluate suicidal thoughts and intentions, and the Suicide Behaviors Questionnaire-Revised (SBQ-R) to assess past suicidal behaviors and future risk.

Results: Confirmatory factor analysis supported a one-factor structure of the SINAS, which was invariant across gender groups. The scale demonstrated strong internal consistency and good test-retest reliability over a two-week interval. Additionally, the SINAS showed significant associations with depressive symptoms, hopelessness, suicide ideation, and suicide risk behaviors, supporting its convergent validity.

Conclusions: Overall, the findings indicate that the Persian version of the SINAS is a valid and reliable instrument for assessing suicidal intrusions in both clinical and research settings in Iran.

自杀企图患者波斯语版自杀入侵属性量表（SINAS）的心理测量特征。

背景：自杀入侵属性量表（SINAS）是一种简短的自我报告量表，旨在评估自杀入侵的频率、痛苦和可控制性——与自杀或其后果有关的生动的、不可控制的心理图像和想法。尽管它具有临床意义，但其心理测量特性仍未得到充分探索。本研究旨在评估波斯语版SINAS的心理测量特性。方法：采用横断面设计。采用方便抽样方法，从德黑兰精神科门诊和医院招募304例有自杀未遂史的门诊患者（18 ~ 65岁，M = 27.27, SD = 8.53），其中男性243例，女性61例。参与者完成了SINAS和贝克抑郁量表ii （BDI-II）来评估抑郁症状，贝克绝望量表（BHS）来衡量对未来的负面预期，贝克自杀意念量表（BSSI）来评估自杀想法和意图，自杀行为问卷-修订版（SBQ-R）来评估过去的自杀行为和未来的风险。结果：验证性因子分析支持SINAS的单因素结构，该结构在不同性别群体中是不变的。该量表在两周的时间间隔内表现出较强的内部一致性和良好的重测信度。此外，SINAS与抑郁症状、绝望、自杀意念和自杀风险行为显著相关，支持其趋同效度。结论：总体而言，研究结果表明，波斯语版本的SINAS是评估伊朗临床和研究环境中自杀入侵的有效和可靠的工具。
