The ward atmosphere of psychiatric care units has a major impact on treatment and satisfaction for both patients and staff. The Ward Atmosphere Scale (WAS) was developed to capture the ward atmosphere in different psychiatric settings and is a well-established instrument for this purpose. However, there is need for an update and revision of the WAS.
The aim of the present study was to test a Swedish version of the revised WAS in terms of its internal consistency, content and construct validity, and usability.
Data collection took place at four psychiatric wards and 31 patients and 34 staff completed the WAS, as well as content and construct validity questions.
Results showed that the WAS had acceptable to satisfactory internal consistency for all subscales, except for autonomy. Low correlation values between the WAS and the Good Milieu Index were obtained, against which construct validity was discussed. Results of the content validity and usability questionnaires indicate that the WAS is easy to understand and complete, but some of the items were difficult for the respondents to understand and some of the subjects were missing aspects of the physical ward environment.
The present study confirms that the Swedish version of the revised WAS can be useful for examining the ward atmosphere in psychiatric care. However, more studies are needed in order to further test the psychometric properties of the WAS and the results of the usability questionnaire may indicate a need to use supplementary instruments in order to capture the physical ward environment as well.
精神科护理单元的病房氛围对患者和工作人员的治疗及满意度有重大影响。病房氛围量表（WAS）旨在捕捉不同精神科环境中的病房氛围，是用于此目的的成熟工具。然而，WAS需要更新和修订。
本研究的目的是测试修订版WAS的瑞典语版本在内部一致性、内容和结构效度以及可用性方面的情况。
在四个精神科病房进行数据收集，31名患者和34名工作人员完成了WAS以及内容和结构效度问题。
结果显示，除自主性分量表外，WAS所有分量表的内部一致性均可接受至令人满意。WAS与良好环境指数之间的相关性值较低，据此讨论了结构效度。内容效度和可用性问卷的结果表明，WAS易于理解和完成，但一些项目受访者难以理解，且一些主题缺少病房物理环境方面的内容。
本研究证实，修订版WAS的瑞典语版本可用于检查精神科护理中的病房氛围。然而，需要更多研究来进一步测试WAS的心理测量特性，可用性问卷的结果可能表明需要使用补充工具来捕捉病房物理环境。
