Annotation	The authors used focus groups, cognitive interviews and multi-trait scaling analysis to develop a 38-item survey to measure expectations regarding ageing (ERA-38). The survey consisted of 10 scales, each representing a domain of expectations. A postal survey was sent to 588 patients aged 65+ cared for by physicians affiliated to the University of California, Los Angeles; 429 (73%, mean age 76, 54% women, 76% white) completed the survey. All scales other than Pain demonstrated good internal consistency reliability and item discrimination. 68% of respondents stated that all or most of the ERA-38 covered things that were important. Construct validity was supported by correlation with age, activities of daily living (ADLs), the Medical Study Short Form -12 physical and mental component scores, and the Geriatric Depression Scale (GDS). The instrument should be useful to investigators interested in measuring expectations regarding age in older people. (RH).
