Pearson Product Moment correlation coefficients were computed for seven frequently used measures of life satisfaction, adjustment, and morale. Data on the seven instruments were collected from 259 subjects over the age of 60 representing three clusters: institutionalized older people, those with limited ambulation, and "community" aged. Intercorrelations among the measures indicate a high level of interrelationship.
计算了皮尔逊积矩相关系数，用于衡量生活满意度、适应能力和士气的七种常用指标。从259名60岁以上的受试者中收集了这七种工具的数据，这些受试者代表三个群体：机构养老的老年人、行动不便者和“社区”老年人。这些指标之间的相互关系表明它们之间存在高度的相关性。
