Tóm tắt	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 Zarit Burden Interview (ZBI) is the most widely used self-report measure of caregiver burden — the physical, emotional, social, and financial strain experienced by people who care for an impaired older relative, most often someone with dementia. Originating in Steven Zarit, Karen Reever, and Julie Bach-Peterson's 1980 study of relatives of impaired elderly, the instrument asks caregivers to rate how often they feel a series of burdens, such as feeling that caregiving harms their health, social life, or finances, or that they could do a better job. The standard version has 22 items rated 0 (never) to 4 (nearly always), summing to a 0–88 total in which higher scores mean greater burden. Short forms (12-item) and a 4-item screen exist for quick assessment. The ZBI is a cornerstone of family-gerontology and dementia-care research and a routine outcome in caregiver-support interventions.
