This study aimed to determine the reliability and validity of the Stroke
and Aphasia Quality of Life Scale (SAQOL-39 g) and its Mandarin adaptation
SAQOL-CSg in Singaporean stroke patients. METHOD: First-time stroke survivors
were recruited at three months post-stroke and underwent a series of
questionnaires in their dominant language (English/Mandarin). This included:
SAQOL-39 g/CSg, National University Hospital System (NUHS) Aphasia Screening
Test, Barthel Index, Modified Rankin Scale, Mini Mental State Examination,
Frontal Assessment Battery, Center for Epidemiologic Studies Depression Scale and
the Eurol-Qol Health Questionnaire (EQ-5D). The SAQOL-39 g/SAQOL-CSg was repeated
within 1 week (+/- 6 days). RESULTS: Ninety-four participants (96.9%) were able
to self-report and their results presented here. Both the SAQOL-39 g/SAQOL-CSg
showed good internal consistency (alpha = 0.96/0.97), test-retest reliability
(ICC= 0.99/0.98), convergent (rs =0.64-0.81 and 0.66-0.88, respectively) and
discriminant (rs = 0.35-0.53 and 0.48-0.62, respectively) validity. The
correlation between the SAQOL-39 g and the EQ-5D Visual Analogue Scale was 0.27.
Further inspection of the EQ-5DVAS scores revealed correlations in different
directions for Malay versus Chinese participants. CONCLUSIONS: Both the SAQOL-39
g and SAQOL-CSg demonstrated good reliability and validity. Our results suggested
some influence of ethnicity in self-rating of health status in relation to
SAQOL-39 g scores. Further research is warranted to examine its use with stroke
survivors with greater stroke severity and over time. Implications for
Rehabilitation Validation of SAQOL in Singapore: Both the SAQOL-39g and the
SAQOL-CSg may be used to measure the HRQoL of stroke survivors with and without
aphasia in Singapore. Further investigation is required to examine use with
stroke survivors with greater stroke severity and over time.
