Abstract

Objective: This study aimed to examine the psychometric properties of the English version of the Self-Stigma Scale-Short (SSS-S), a nine-item self-report self-stigma measurement, among U.S. adults with psychiatric disabilities.

Method: We obtained reliability and validity evidence from a sample of 275 adults with psychiatric disabilities.

Results: Exploratory factor analysis (EFA; n = 139) yielded a two-factor solution that accounts for 64.97% of the variance. Confirmatory factor analysis (CFA; n = 136) was conducted to compare alternative solutions, including a single-factor model, a two-correlated-factor model, a three-correlated-factor model, and a bifactorial model. The CFA results supported the bifactor S·I - 1 model as a superior latent factor structure for the SSS-S. The coefficient ω of the SSS-S was .94, indicating excellent internal reliability. Concurrent validity of the SSS-S was supported by significant positive correlations with societal stigma and psychiatric symptom severity, and negative correlations with psychiatric disability acceptance, general self-efficacy, and hope.

Conclusions and implications for practice: The overall findings concluded that the English version of the SSS-S demonstrated reliable and valid scores and a primarily unidimensional structure of self-stigma among U.S. adults with psychiatric disabilities. Given the adverse impact of self-stigma and its relationships with recovery-related constructs shown in this study, the routine use of the SSS-S is recommended in psychiatric rehabilitation settings.

单维与多维：美国成年精神残疾人士自我耻辱感量表-简表（SSS-S）的双因素因子结构。

研究目的本研究旨在检验英文版《自我污名化量表-简版》（SSS-S）的心理测量特性，该量表是一种由九个项目组成的自我报告式自我污名化测量方法，适用于美国成年精神残疾人士：方法：我们从 275 名成年精神残疾者样本中获得了信度和效度证据：探索性因子分析（EFA；n = 139）得出了一个双因子解，占方差的 64.97%。进行了确认性因子分析（CFA；n = 136），以比较其他解决方案，包括单因子模型、双相关因子模型、三相关因子模型和双因子模型。CFA 结果表明，双因子 S-I - 1 模型是 SSS-S 的一个较好的潜在因子结构。SSS-S 的系数 ω 为 0.94，表明其内部信度极佳。SSS-S与社会耻辱感和精神症状严重程度呈显著正相关，与精神残疾接受度、一般自我效能感和希望呈负相关，这证明了SSS-S的并发有效性：总体研究结果表明，SSS-S 的英文版在美国成年精神残疾人士中显示出可靠有效的分数和主要的单维度自我污名结构。鉴于本研究中显示的自我烙印的负面影响及其与康复相关结构的关系，建议在精神康复机构中常规使用 SSS-S。(PsycInfo Database Record (c) 2023 APA，保留所有权利）。
