PMID 37820152WHAT IT FOUND
A Portuguese resilience questionnaire for Brazilian older adults can be used to assess five areas: support network, relationships, self-efficacy, optimism, and perceived resources.
It showed acceptable total score agreement and stability, but the five areas alone were not reliable enough.
Key findings
01The final model had acceptable fit: TLI was 0.959, RMSEA was 0.03, and the chi-square test was not significant (p=0.105).
02The total scale had acceptable reliability (Cronbach’s alpha 0.705), but the individual factors did not (all below 0.7).
03Test-retest reliability was good, with ICC greater than 0.75 and less than 0.90.

What it does not show
The validity sample was a convenience sample of 187 hospital outpatients in one Brazilian city, and interviews with 195 people yielded 8 excluded protocols, so the analysed sample was smaller than the 220 target based on 10 times the 22 items. The study used exploratory factor analysis and did not do confirmatory factor analysis, so the five-factor structure needs testing in new samples. The five subscales had Cronbach’s alpha below 0.7, so subscale scores should not be treated as reliable. Retest and inter-rater reliability were based on few participants and paired raters, which can make agreement look very high. Participants were mostly younger older adults (mean 69.23 years) and excluded people with dementia, terminal illness, institutional residence, or frequent hospitalisation, so results may not apply to frailer older adults. Reverse-scored items caused understanding problems, and some were removed to simplify the factor model.
The easy way to misread this
Do not read the acceptable total-score reliability as proof that the scale predicts resilience outcomes or improves care. The study only tested the questionnaire's measurement properties, and the five subscales did not reach acceptable reliability, so use the total score cautiously.
