An investigation of the psychometric properties of the Chinese (Cantonese) version of Subjective Index of Physical and Social Outcome (SIPSO).

OBJECTIVE

The objectives of this study were 1) to translate and make cultural adaptations to the English version of the SIPSO questionnaire to create a Chinese (Cantonese) version, 2) evaluate the internal consistency, test-retest reliability the C-SIPSO questionnaire, and 3) compare the SIPSO-C scores of stroke survivors with different demographic characteristics to establish the discriminant validity of the questionnaire Design: Translation of questionnaire, cross sectional study.

SETTING

University-based clinical research laboratory. Subjects Community-dwelling chronic stroke survivors.

INTERVENTIONS

Not applicable.

MAIN MEASURES

Subjective Index of Physical and Social Outcome, Geriatric Depression Scale, 10-metre Walk test.

RESULTS

Two bilingual professional translators translated the SIPSO questionnaire independently. An expert panel comprising five registered physiotherapists verified the content validity of the final version (C-SIPSO). C-SIPSO demonstrated good internal consistency (Cronbach's α = 0.83) and excellent test-retest reliability (ICC = 0.866) in ninety-two community dwelling chronic stroke survivors. Stroke survivors scored higher than 10 in the Geriatric Depression Scale ( U = 555.0, P < 0.001) and with the comfortable walking speed lower than 0.8ms ( U = 726.5; P = 0.012) scored significantly lower on SIPSO-C.

CONCLUSION

SIPSO-C is a reliable instrument that can be used to measure the level of community integration in community-dwelling stroke survivors in Hong Kong and southern China. Stroke survivors who were at high risk of minor depression and with limited community ambulation ability demonstrated a lower level of community integration as measured with SIPSO-C.
