Tiivistelmä	The Philadelphia Geriatric Center Morale Scale (PGCMS) is a classic self-report instrument for measuring morale — a broad sense of psychological well-being — in older adults. Developed by M. Powell Lawton and presented in revised 17-item form in his 1975 Journal of Gerontology paper, the scale defines morale as a basic sense of satisfaction with oneself, a feeling that one has a place in one's environment, and an acceptance of what cannot be changed. Principal-components analysis of the original items identified three reproducible factors: Agitation, Attitude Toward Own Aging, and Lonely Dissatisfaction. Respondents answer simple yes/no questions, which are keyed and summed so that higher totals indicate higher morale. The PGCMS became one of the most influential measures of subjective well-being in social gerontology and remains widely used in research on quality of life and successful aging.	The Expectations Regarding Aging (ERA) Survey measures the degree to which an individual expects physical, mental, and cognitive functioning to decline as a normal and unavoidable part of growing older. Developed by Catherine Sarkisian and colleagues at UCLA, the original 38-item version (ERA-38, 2002) and the widely used 12-item short form (ERA-12, 2005) capture 'age expectations' — a self-perception-of-aging construct that predicts health behaviors and outcomes. Items are answered on a Likert scale and scored into three domain scores (expectations regarding physical health, mental health, and cognitive function) plus a total, conventionally rescaled to 0–100 where higher scores indicate higher (more positive) expectations. Low expectations — believing that decline is inevitable — are associated with less physical activity, lower help-seeking, and worse outcomes, making the ERA a key tool for studying how beliefs about aging shape behavior.
