Healthcare professionals can be a source of stigma and discrimination for people with mental illness, and anti-stigma programs are needed for this target group. However, there is no validated German language scale to assess attitudes of healthcare professionals towards people with mental illness. This study had the aim to validate the German language version of the Opening Minds Stigma Scale for Health Care Providers (OMS-HC), a self-report measure of stigmatizing attitudes. Staff (n = 392) on general psychiatric inpatient wards (excluding child, forensic and geriatric psychiatry) at five psychiatric hospitals in Switzerland (n = 3) and Germany (n = 2) participated in the study. The internal consistency of the OMS-HC was examined as well as its factor structure using exploratory and confirmatory factor analyses. To assess the scale’s concurrent validity, we used the Social Distance Scale. Internal consistency for the OMS-HC total score was good (α = 0.74), acceptable for the subscales Attitudes (α = 0.62) and Social Distance (α = 0.69), and poor for the Disclosure subscale (α = 0.55). The original three-factor structure fit our data well. The OMS-HC total score and the Social Distance subscale score were significantly correlated with the Social Distance Scale, supporting concurrent validity. The German version of the OMS-HC demonstrated satisfactory psychometric properties and can be recommended for future research and intervention evaluation.

德文版《医疗人员开放思想耻辱量表》（OMS-HC）的心理计量学评估

对于精神疾病患者，医疗保健专业人员可能会成为污名和歧视的来源，因此该目标人群需要采取反污名计划。但是，尚无经过验证的德语量表来评估医疗保健专业人员对患有精神疾病的人的态度。这项研究的目的是验证德语版本的卫生保健提供者的开放心智柱头量表（OMS-HC），这是一种自我报告的衡量污名态度的方法。瑞士（n = 3）和德国（n = 2）的五家精神病医院的普通精神科住院病房（不包括儿童，法医和老年精神病学）的工作人员（n = 392）参加了该研究。使用探索性和确认性因素分析检查了OMS-HC的内部一致性及其因素结构。为了评估量表的并发有效性，我们使用了社交距离量表。OMS-HC总分的内部一致性良好（α= 0.74），对于分量表态度（α= 0.62）和社交距离（α= 0.69）是可以接受的，而对于Disclosure分量表（α= 0.55）是差的。原始的三因素结构非常适合我们的数据。OMS-HC总分和“社交距离”量表得分与“社交距离量表”显着相关，支持并发效度。OMS-HC的德语版本显示出令人满意的心理测量特性，可以推荐用于将来的研究和干预评估。而对于Disclosure次评量表则很差（α= 0.55）。原始的三因素结构非常适合我们的数据。OMS-HC总分和“社交距离”量表得分与“社交距离量表”显着相关，支持并发效度。OMS-HC的德语版本显示出令人满意的心理测量特性，可以推荐用于将来的研究和干预评估。而对于Disclosure次评量表则很差（α= 0.55）。原始的三因素结构非常适合我们的数据。OMS-HC总分和“社交距离”量表得分与“社交距离量表”显着相关，支持并发效度。OMS-HC的德语版本显示出令人满意的心理测量特性，可以推荐用于将来的研究和干预评估。
