Research addressing perceptions of housing in people with Parkinson's disease (PD) is rare, and existing instruments capturing perceived aspects of housing are rarely used. Perceived housing comprises of several domains and is associated with health in general older populations. One such domain is meaning of home, captured by the Meaning of Home Questionnaire (MOH). The aim of this study was to evaluate psychometric properties of the MOH among people with PD.
The MOH was administrated to 245 participants with PD (mean age = 69.9 years; mean PD duration = 9.7 years). The instrument consisted of four sub-scales with 28 items, each with 11 response options (strongly disagree = 0; strongly agree = 10). We evaluated data quality, structural validity (factor analysis), construct validity (i.e., testing correlations with relevant constructs according to pre-defined hypotheses), corrected item total correlations, floor and ceiling effects and internal consistency.
The data quality was high (0-1.2% missing data). The exploratory factor analysis suggested removal of five items and revealed three new factors; "My home is my castle", "My home is my prison" and "My home is my social hub". The 23-item MOH showed statistically significant correlations with life satisfaction, usability and ADL dependence, while not correlated with number of environmental barriers. These findings were largely as hypothesised, thus supporting construct validity (both convergent and discriminant). The corrected item total correlations were >0.3 for all items and the internal consistency was >0.70 for all sub-scales. No floor or ceiling effects were reported except for the sub-scale "My home is my castle" (ceiling effect = 15.6%).
The 23-item MOH version with three new sub-scales is sufficiently reliable and valid for use in PD populations. This paves the way for further research of meaning of home among people with PD, using the 23-item MOH version.
针对帕金森病（PD）患者住房认知的研究很少，而且现有的住房认知评估工具也很少被使用。住房认知包括几个领域，与一般老年人群的健康相关。其中一个领域是家庭意义，由家庭意义问卷（MOH）捕捉。本研究旨在评估 MOH 在 PD 患者中的心理测量特性。
向 245 名 PD 患者（平均年龄=69.9 岁；平均 PD 病程=9.7 年）施测 MOH。该工具包含四个子量表，共 28 个项目，每个项目有 11 个回答选项（非常不同意=0；非常同意=10）。我们评估了数据质量、结构效度（因子分析）、构念效度（即根据预先定义的假设，测试与相关构念的相关性）、校正项目总分相关、地板和天花板效应以及内部一致性。
数据质量高（0-1.2%缺失数据）。探索性因子分析建议删除 5 个项目，揭示了三个新的因子；“我的家是我的城堡”、“我的家是我的牢笼”和“我的家是我的社交中心”。23 项 MOH 与生活满意度、可用性和 ADL 依赖呈统计学显著相关，而与环境障碍数量无关。这些发现与假设基本一致，因此支持构念效度（同时具有收敛性和区分度）。所有项目的校正项目总分相关系数均>0.3，所有子量表的内部一致性系数均>0.70。除了“我的家是我的城堡”子量表（天花板效应=15.6%）外，没有报告地板或天花板效应。
具有三个新子量表的 23 项 MOH 版本在 PD 人群中具有足够的可靠性和有效性。这为使用 23 项 MOH 版本进一步研究 PD 患者的家庭意义铺平了道路。
