Expectations Regarding Aging Survey

The ERA-38 is the original 38-item instrument with broader content coverage; the ERA-12 is a 12-item short form built from it, comprising three four-item subscales (physical health, mental health, cognitive function). The short form was validated to retain strong reliability (subscale alphas above 0.74) and to explain over 88% of the variance in the ERA-38 total, so it is preferred when respondent burden matters while the longer version offers finer-grained measurement.

Higher scores mean higher — more positive — expectations, indicating that the respondent rejects the idea that decline in functioning is an inevitable part of aging. Scores are conventionally rescaled to 0–100, so a score near 100 reflects strongly positive expectations and a score near 0 reflects strongly negative (fatalistic) expectations. Items are keyed and negatively worded items recoded so this direction is consistent across the whole scale.

Because beliefs shape behavior. Older adults who expect decline to be inevitable are less likely to exercise, more likely to dismiss symptoms as 'just age,' and less likely to seek care, whereas those with higher expectations engage more in prevention and treatment. The ERA was developed precisely to capture this lever, and validation studies link low expectations to lower physical activity and help-seeking, which is why interventions sometimes target expectations directly to improve health behavior.
