Resumé	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.	The Tilburg Frailty Indicator (TFI) is a self-report questionnaire that measures frailty in older adults across three domains — physical, psychological, and social. Developed by Robbert Gobbens and colleagues at Tilburg University and published in 2010, it operationalizes an explicit 'integral conceptual model of frailty' in which frailty is a dynamic state arising from losses in one or more functioning domains, itself driven by life-course determinants such as age, sex, multimorbidity, and life events. Part A of the instrument records these determinants; Part B comprises 15 items that sum to a 0–15 frailty score, with a cut point of 5 commonly used to flag frailty. Unlike purely physical phenotypes, the TFI deliberately incorporates psychological (mood, anxiety, coping, cognition) and social (living alone, social relationships, support) components, reflecting the social-gerontological view that frailty is more than a biomedical syndrome.
