Housing-related control beliefs are associated with aspects of health among older people in general. Research on Parkinson's disease (PD) focusing on perceptions of the home are rare and instruments capturing perceived aspects of home have seldom been used.
To evaluate psychometric properties of the external Housing-related Control Beliefs Questionnaire (HCQ) among people with PD.
The external HCQ were administrated to 245 participants with PD, (mean age = 69.9 years; mean PD duration = 9.7 years). External HCQ has 16-items, with five response options. The psychometric properties evaluated were data quality, structural validity (factor analysis), floor and ceiling effects, corrected item total correlations, internal consistency and construct validity (testing correlations with relevant constructs according to pre-defined hypotheses).
Data quality was high. Structural validity showed a unidimensional construct with removal of two items. Homogeneity was questionable, but strengthened after the removal of the two items. For the 14-item version internal consistency was α = 0.78 and SEM 4.47. Corrected item total correlation ranged between 0.31 and 0.54 and no floor or ceiling effects. Significant correlations with relevant constructs supported the construct validity.
Taken together, the psychometric results suggest a 14-item version of the external HCQ to be sufficiently reliable and valid for use in the PD population. The results pave the way for further studies, using the HCQ to analyse how perceptions of control of the home may be associated with health among people ageing with PD.
住房相关的控制信念与老年人的健康方面有关。针对帕金森病（PD）的家庭认知研究较为少见，且很少使用评估家庭认知方面的工具。
评估外部住房相关控制信念问卷（HCQ）在 PD 患者中的心理测量学特性。
对 245 名 PD 患者（平均年龄 69.9 岁；平均 PD 病程 9.7 年）进行外部 HCQ 问卷调查。外部 HCQ 共有 16 个项目，5 个回答选项。评估的心理测量学特性包括数据质量、结构有效性（因子分析）、地板效应和天花板效应、校正项目总分相关性、内部一致性和结构有效性（根据预先定义的假设测试与相关结构的相关性）。
数据质量较高。结构有效性显示，在去除两个项目后，具有单维度结构。同质性值得怀疑，但在去除这两个项目后得到了加强。14 项版本的内部一致性为α=0.78，SEM 为 4.47。校正项目总分相关性在 0.31 至 0.54 之间，不存在地板效应或天花板效应。与相关结构的显著相关性支持了结构有效性。
综合来看，心理测量学结果表明，外部 HCQ 的 14 项版本在 PD 人群中具有足够的可靠性和有效性。这些结果为进一步使用 HCQ 分析家庭控制感如何与 PD 患者的健康相关铺平了道路。
