There is a need to develop a questionnaire that measures nurses' verbal and social interactions (VSI) with their patients from the nurses' perspective as well as from the patients' perspective in the psychiatric and especially in the forensic psychiatric field. The major aim of the present study was to determine the construct validity and the internal consistency reliability of the VSI questionnaire. The study had a methodological and developmental design and was carried out in four steps: construction of the items, face validity, data collection and data analysis. The number of items was reduced from 50 to 21. The factor analysis of the final 21 items resulted in three quite distinct factors, namely, 'inviting the patient to establish a relationship', 'showing interest in the patients' feelings, experiences and behaviour' and 'helping the patients to establish structure and routines in their everyday life'. The results showed satisfactory psychometric properties in terms of content validity, construct validity and the internal consistency reliability of the questionnaire.
有必要开发一种问卷，该问卷能从护士以及患者的角度衡量护士在精神科，尤其是法医精神科领域与患者的言语和社交互动（VSI）。本研究的主要目的是确定VSI问卷的结构效度和内部一致性信度。该研究采用了方法学和发展性设计，并分四个步骤进行：项目构建、表面效度、数据收集和数据分析。项目数量从50个减少到21个。对最终的21个项目进行因子分析，得出了三个截然不同的因子，即“邀请患者建立关系”、“对患者的感受、经历和行为表现出兴趣”以及“帮助患者在日常生活中建立结构和常规”。结果表明，该问卷在内容效度、结构效度和内部一致性信度方面具有令人满意的心理测量特性。
