Cross-cultural adaptation of Life Satisfaction Checklist-11 among persons with stroke in China: A reliability and validity study.

OBJECTIVE

The aim of the present study was to develop a cross-cultural adaptation and to evaluate the validity and reliability of a Chinese version of the LiSat-11 test.

METHODS

LiSat-11 was translated into Chinese according to standardized procedures. A cross-sectional descriptive study was conducted to examine its reliability and validity, in accordance to COnsensus-based Standards for the election of health Measurements Instruments guidelines, among persons with stroke approximately 3 years after their discharge from rehabilitation. Participants completed the LiSat-11, 36-Item Short-Form Health Survey (SF-36), National Institutes of Health Stroke Scale (NIHSS), modified Rankin Scale (mRS), Barthel Index (BI) and Hospital Anxiety and Depression Scale (HADS). To examine the test-retest reliability, thirty of these participants completed LiSat-11 again after 2 weeks.

RESULTS

In total, 60 persons with stroke were recruited. The Chinese version of LiSat-11 demonstrated good internal consistency with Cronbach's alphas at 0.82. Ceiling effects were found in five of the eleven items of LiSat-11, and there was a floor effect in one item. LiSat-11 had moderate to high correlations with SF-36 with Spearman's correlation coefficient (rho) ranging from 0.44 to 0.73 (p < 0.01) in a concurrent validity test, and high correlations were also found between LiSat-11 and HADS-A/D in a convergent validity test with rho = -0.63/-0.67 (p < 0.01). Low correlations with NIHSS, BI and mRS were found in a divergent validity test, rho = -0.25, 0.17 and -0.26, respectively.

CONCLUSION

The current study verified that the translated Chinese version of the Life Satisfaction Checklist-11 is a reliable and valid tool for measuring the life satisfaction of persons with chronic stroke.
