Reliability and validity of scores of a Chinese version of the Frenchay Activities Index.

OBJECTIVE

To develop a Chinese version of the Frenchay Activities Index (FAI-C) and evaluate the reliability and validity of its scores.

DESIGN

A 2-week test-retest study.

SETTING

Chinese community in Vancouver, BC, Canada.

PARTICIPANTS

Data were collected using a convenience sample of Chinese immigrants living in Vancouver, BC, Canada. Of the 73 participants, data from 66 participants were included in the analysis. The total sample included 2 subsamples: community dwelling (n=32), and assisted-living (n=34). Participants were 65 years or older, lived in Canada for more than 5 years, and were able to read Chinese.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

FAI-C scores.

RESULTS

Test-retest reliability of the FAI-C scores assessed using an intraclass correlation coefficient was .86 (95% confidence interval [CI], .79-.92) for the total sample, .89 (95% CI, .78-.94) for the community-dwelling subsample, and .71 (95% CI, .50-.85) for the assisted-living subsample. The minimal detectable difference at the 95% CI was 8.64. Correlations between the FAI-C and the Reintegration to Normal Living Index (r=.61, P<.01), Activities-specific Balance Confidence Scale (r=.55, P<.01), and Timed Up & Go test (r=-.68, P<.01) were in the a priori hypothesized direction and magnitude.

CONCLUSIONS

The FAI-C scores are reliable and there is support for validity. This tool enables us to measure social participation level in the Chinese-speaking population.
