To assess the psychometric properties of the Persian version of the short Schema Mode Inventory (SMI).
The short SMI was translated into Persian by three clinical psychology professors and then back-translated into English by two professors in English language. Between 2017 and 2018, patients from Iran Psychiatric Hospital and Rasoul Akram Hospital who were diagnosed with personality disorder in Axis II by a psychiatrist and had minimum education of middle school were included. Controls included students and staff of the Iran Medical Sciences University who had minimum education of middle school. All participants were asked to complete the short SMI and the Young Schema Questionnaire - Short Form (YSQ-SF). Internal consistency (Cronbach's alpha), test-retest reliability, confirmatory factor analysis, internal correlation of schema mode subscales, and correlation between short SMI and YSQ-SF were assessed.
Of 406 participants, 205 (50.7%) were patients and 201 (49.3%) were controls. The fitness indices indicated that the 14-factor model was reliable, with χ = 12917.97, p < 0.001, df = 5795, χ/df = 2.23, CFI = 0.96, NNFI = 0.96 SRMR = 0.08, and RMSEA = 0.05. The internal consistency of the short SMI was satisfactory (M = 0.94). Among 34 participants in the control group who completed the short SMI again after 2 weeks, test-retest reliability was high (Pearson correlation coefficient = 0.88, p < 0.001). The short SMI and YSQ-SF correlated strongly in terms of the overall scale and most subscales. The patient and control groups differed significantly in most subscales.
Psychometric properties of the Persian version of the short SMI showed good validity and reliability. It can be used in clinical and research settings.
评估短式心理模式量表（SMI）波斯语版本的心理计量特性。
三位临床心理学教授将短式 SMI 翻译成波斯语，然后由两位英语教授将其回译为英语。2017 年至 2018 年，伊朗精神病院和 Rasoul Akram 医院的患者被诊断为轴 II 人格障碍的精神科医生，最低教育程度为中学，对照组包括伊朗医科大学的学生和员工，最低教育程度为中学。所有参与者均被要求完成短式 SMI 和年轻心理模式问卷-短式（YSQ-SF）。评估内部一致性（Cronbach's alpha）、测试-重测信度、验证性因素分析、心理模式分量表的内部相关性以及短式 SMI 与 YSQ-SF 的相关性。
在 406 名参与者中，205 名（50.7%）为患者，201 名（49.3%）为对照组。拟合指数表明，14 因素模型具有可靠性，χ=12917.97，p<0.001，df=5795，χ/df=2.23，CFI=0.96，NNFI=0.96，SRMR=0.08，RMSEA=0.05。短式 SMI 的内部一致性令人满意（M=0.94）。在对照组的 34 名参与者中，有 34 名在 2 周后再次完成短式 SMI，重测信度较高（Pearson 相关系数=0.88，p<0.001）。短式 SMI 和 YSQ-SF 在整体量表和大多数分量表上相关性较强。患者组和对照组在大多数分量表上差异显著。
短式 SMI 波斯语版本的心理计量特性显示出良好的有效性和可靠性。它可以在临床和研究环境中使用。
