The Opening Minds Stigma Scale for Health Care Providers (OMS-HC) is a widely used questionnaire to measure the stigmatising attitudes of healthcare providers towards patients with mental health problems. The psychometric properties of the scale; however, have never been investigated in Hungary. We aimed to thoroughly explore the factor structure of the OMS-HC and examine the key psychometric properties of the Hungarian version.
The OMS-HC is a self-report questionnaire that measures the overall stigmatising attitude by a total score, and three subscales can be calculated: Attitude, Disclosure and Help-seeking, and Social Distance. Our study population included specialists and trainees in adult and child psychiatry (n = 211). Exploratory and confirmatory factor analyses were performed, and higher-order factors were tested. We calculated the test-retest reliability on a subgroup of our sample (n = 31) with a follow-up period of 1 month. The concurrent validity of the scale was measured with the Mental Illness: Clinician's Attitudes-4 scale (MICA-4).
Three factors were extracted based on a parallel-analysis. A bifactor solution (a general factor and three specific factors) showed an excellent model-fit (root mean square error of approximation = 0.025, comparative fit index = 0.961, and Tucker-Lewis index = 0.944). The model-based reliability was low; however, the general factor showed acceptable reliability (coefficient omega hierarchical = 0.56). The scale demonstrated a good concurrent validity with the MICA-4 [intraclass correlation coefficient (ICC) = 0.77]. The test-retest reliability was excellent for the general factor (ICC = 0.95) and good for the specific factors (ICC = 0.90, 0.88, and 0.84, respectively).
The three dimensions of the OMS-HC was confirmed, and the scale was found to be an adequate measure of the stigmatising attitude in Hungary. The bifactor model is more favourable as compared to the three correlated factor model; however, despite the excellent internal structure, its model-based reliability was low.
《医护人员开放思维歧视量表》（OMS-HC）是一种广泛用于测量医护人员对心理健康问题患者的歧视态度的问卷。然而，该量表的心理测量特性从未在匈牙利进行过研究。我们旨在深入探讨 OMS-HC 的因素结构，并检验匈牙利语版本的关键心理测量特性。
OMS-HC 是一种自我报告问卷，通过总分衡量整体歧视态度，同时可以计算出三个分量表：态度、披露和寻求帮助以及社会距离。我们的研究人群包括成人和儿童精神病学的专家和受训者（n=211）。进行了探索性和验证性因素分析，并测试了高阶因素。我们对样本的一个亚组（n=31）进行了测试-重测信度，随访期为 1 个月。该量表的同时效度用《精神疾病：临床医生态度-4 量表》（MICA-4）进行测量。
根据平行分析提取了三个因素。双因素解决方案（一个总因素和三个特定因素）显示出极好的模型拟合度（近似均方根误差为 0.025，比较拟合指数为 0.961，塔克-刘易斯指数为 0.944）。基于模型的可靠性较低；然而，总因素表现出可接受的可靠性（等级 omega 系数为 0.56）。该量表与 MICA-4 具有良好的同时效度[组内相关系数（ICC）=0.77]。总因素的测试-重测信度极好（ICC=0.95），特定因素的信度良好（ICC=0.90、0.88 和 0.84）。
OMS-HC 的三个维度得到了确认，并且该量表在匈牙利被证明是一种评估歧视态度的适当工具。双因素模型优于三个相关因素模型；然而，尽管内部结构良好，但基于模型的可靠性较低。
