PURPOSE/OBJECTIVE This study investigated the psychometric properties of a newly developed Received Social Support Scale for Persons with Serious Mental Illness (rSSS-SMI). The rSSS-SMI measures three support domains: Day-to-Day Living support, Mental Health Support, and Adherence Support. RESEARCH METHOD/DESIGN (a) to examine the item quality of the rSSS-SMI, (b) to investigate the construct validity and verify the dimensionality of the rSSS-SMI, and (c) to investigate the reliability and validity of the rSSS-SMI scores. A sample of 267 community-based case management service recipients with SMI completed the rSSS-SMI and three additional scales (Interpersonal Support Evaluation List-Short Form [ISEL-12]; Symptom Checklist-6 [SCL-6]; Satisfaction with Life Scale [SWLS]). RESULTS Three items were dropped from the scale resulting in a 21-item scale. Confirmatory factor analysis and Item Response Theory analyses revealed our proposed three-factor model fit the data best, with average loadings at .74 (SD = .09). The three-factor model had higher item discrimination and item difficulty parameters than the one-factor model. The rSSS-SMI achieved strong internal consistency with estimates of .94 (full scale), .83 (Day-to-Day Living Support), .84 (Mental Health Support) and .76 (Adherence Support). The three-week interval test-retest reliability coefficient was .59. Convergent and discriminant validity evidence revealed a small, positive correlation between the rSSS-SMI and perceived support (ISEL-12) and symptom distress (SCL-6) and a small, negative, nonsignificant relationship with life satisfaction (SWLS). CONCLUSION This study provides preliminary reliability and validity evidence for the rSSS-SMI and confirms our proposed three-factor structure (Day-to-Day Living Support, Mental Health Support, Adherence Support).

严重精神疾病患者社会支持量表：初步量表开发和验证研究。

目的/目标本研究调查了新开发的严重精神疾病患者社会支持量表（rSSS-SMI）的心理测量特性。rSSS-SMI 衡量三个支持领域：日常生活支持、心理健康支持和依从性支持。研究方法/设计 (a) 检查 rSSS-SMI 的项目质量，(b) 研究 rSSS-SMI 的结构有效性并验证维度，以及 (c) 研究 rSSS-SMI 的信度和效度SMI 分数。267 名 SMI 社区案例管理服务接受者样本完成了 rSSS-SMI 和三个附加量表（人际支持评估清单 - 简表 [ISEL-12]；症状检查表 6 [SCL-6]；生活满意度量表[SWLS]）。结果 量表中删除了 3 个项目，使量表由 21 个项目组成。验证性因子分析和项目响应理论分析表明，我们提出的三因子模型最适合数据，平均载荷为 0.74 (SD = 0.09)。三因素模型比一因素模型具有更高的项目区分度和项目难度参数。rSSS-SMI 实现了很强的内部一致性，估计值为 0.94（满量程）、0.83（日常生活支持）、0.84（心理健康支持）和 0.76（依从性支持）。三周间隔重测信度系数为 0.59。收敛和判别效度证据显示，rSSS-SMI 与感知支持 (ISEL-12) 和症状困扰 (SCL-6) 之间存在较小的正相关关系，与生活满意度 (SWLS) 之间存在较小的负相关关系。结论 本研究为 rSSS-SMI 提供了初步的信度和效度证据，并证实了我们提出的三因素结构（日常生活支持、心理健康支持、依从性支持）。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。
