Development of resilience scale for older adults.

Objectives: Older adults are more likely to encounter adverse life events and have protective factors that are different from other populations. Currently, there is no resilience scale designed exclusively for older adults. This study aims at developing a new measurement scale for assessing resilience of older adults.

Methods: Items of Resilience Scale for Older Adults (RSOA) was generated from thorough literature review. A multiple stage method was applied to examine the psychometric properties of the scale. In pretesting, items that did not meet the psychometric criteria were removed. A sample of 368 older adults was collected in the main survey to perform preliminary item selection and removal, reliability and construct validity analyses. Another survey on 76 samples was then conducted to assess test-retest reliability of the scale.

Results: RSOA that comprised four constructs (personal strength, meaning and purpose of life, family support, and social support) with a total of 15 items was developed with good reliability and validity. Cronbach's α of the scale was 0.882. All the four constructs were found significantly correlated with life satisfaction of older adults.

Conclusions: The RSOA is a reliable means of assessing psychological and physical resilience of older people as well as predicting their satisfaction with life. The study may also provide important information about elderly coping with adversity.
