This article describes the results of a study into the psychometric properties of a questionnaire about student nurses' perceptions of mental health care. The questionnaire was constructed in 2008, but has not yet been tested in terms of construct validity and reliability. A validated questionnaire is essential as a standardized method of analyzing student nurses' perceptions of mental health care.
To investigate the construct validity, an exploratory factor analysis was performed. Reliability was determined by measuring the internal consistency of the questionnaire.
A principal component analysis (PCA) yielded a two-factor solution. The first factor comprised 9 items referring to the views of student nurses on psychiatric patients; the second factor comprised 6 items referring to the views of the students about professional careers in mental health care.
The factor analysis and questionnaire produced two easily interpretable factors covering the same categories as those identified in the literature as determinants of a student nurse's choice for or against a career in mental health care. The questionnaire's construct validity was rated as sufficient, its reliability as acceptable. The problem is the low explained variance (25.6%). The usefulness of the questionnaire is therefore questionable. The usefulness might be improved through the expansion of some of the categories by additional items. Relevant suggestions are made in this article.
本文描述了一项针对学生护士对心理健康护理认知的问卷的心理测量学特性的研究结果。该问卷于 2008 年构建，但尚未在结构有效性和可靠性方面进行测试。作为分析学生护士对心理健康护理认知的标准化方法，验证有效的问卷是必不可少的。
为了研究结构有效性，进行了探索性因素分析。通过测量问卷的内部一致性来确定可靠性。
主成分分析（PCA）得出了一个两因素解决方案。第一个因素包括 9 个项目，涉及学生护士对精神病患者的看法；第二个因素包括 6 个项目，涉及学生对心理健康护理职业的看法。
因子分析和问卷产生了两个易于解释的因素，涵盖了文献中确定的决定学生护士选择或反对心理健康护理职业的相同类别。问卷的结构有效性被评为充分，可靠性可接受。问题是解释方差低（25.6%）。因此，问卷的有用性值得怀疑。通过增加一些项目来扩展某些类别，可以提高问卷的有用性。本文提出了一些相关建议。
