目的：研究费城老年士气量表（PGMS）在中国香港老年人群中的心理测量特性。设计和方法：研究包括两个队列：(a) 759名居住在社区的70岁及以上的参与者，他们是作为全港健康调查的一部分招募的，并于1993-1994年接受了采访；(b) 1995-1996年住在长期护理机构的388名参与者。认知障碍（简略智力测验得分低于7分）或因其他原因无法回答问题的参与者被排除在外。采用15项PGMS量表。采用Rasch二分类模型对PGMS的效度进行评估，并采用先前中文版验证过的15项老年抑郁量表（Geriatric Depression Scale）检验其并发效度。结果：验证性因素分析确定了三个潜在因素与白种人的发现相似；然而，并非所有的拟合优度指数都是可接受的。一个探索性因子分析使用主轴因子和最大旋转揭示了两个潜在的因素解释35%的总方差：调和老化和非紧张的影响。当应用于机构样本时，有些项目是多余的。同时效度显示，调和老化和非紧张情绪域与老年抑郁量表有较好的相关性（r = -0.72和r = -0.56）。女性性别、年龄较大和居住在机构与较低的士气有关。意义：PGMS是一种有效的香港华人老年人生活质量测量方法，但其心理测量特性与白种人略有不同。
Purpose: We examine the psychometric properties of the Philadelphia Geriatric Morale Scale (PGMS) in an elderly Chinese population in Hong Kong.Design and Methods: The study consisted of two cohorts: (a) 759 participants aged 70 years and older living in the community who were recruited as part of a territory-wide health survey and interviewed in 1993-1994; and (b) 388 participants living in long-term-care institutions in 1995-1996. Participants who were cognitively impaired (Abbreviated Mental Test score less than 7) or who could not answer questions for other reasons were excluded. The 15-item PGMS was administered. The Rasch dichotomous model was used to assess the validity of the PGMS, and the 15-item Geriatric Depression Scale, previously validated in Chinese, was also administered to examine the concurrent validity.Results: A confirmatory factor analysis identified three underlying factors similar to findings among Caucasians; however, not all the goodness-of-fit indices were acceptable. An exploratory factor analysis using principal axis factoring and promax rotation revealed two underlying factors that explained 35% of the total variance: reconciled aging and unstrained affect. Some items were redundant when applied to the institutional sample. Concurrent validity was demonstrated by the good correlation between the reconciled aging and unstrained affect domains and the Geriatric Depression Scale (r = -0.72 and r = -0.56 respectively). Female gender, older age, and residence in institutions were associated with lower morale.Implications: The PGMS is a valid quality-of-life measure in elderly Hong Kong Chinese persons, but its psychometric properties are slightly different from those for Caucasians.
