【 摘 要 】

Abstract Background The Stroke Specific Quality of Life 2.0 (SS-QoL 2.0) is a widely used scale that has been cross-culturally adapted to many languages including Yoruba, one of the three major Nigerian languages. Non-availability of SS-QoL 2.0 in Hausa, the indigenous language of Northern Nigeria has restricted its use in Hausa stroke-survivors (SSV). This study was aimed at cross-culturally adapting SS-QoL 2.0 to Hausa and assessing validity and reliability of the Hausa version. The English version of SS-QoL 2.0 was cross-culturally adapted to Hausa following the American Association of Orthopaedic Surgeons’ guideline. A final Hausa version (FHV) was produced through forward and back-translations, expert committee review, pretesting and cognitive debriefing interview. The FHV was investigated for test-retest reliability, internal consistency, convergent, construct and known-group validity on 86 consenting Hausa SSV. Hausa version of WHOQoL-BREF was used to assess convergent validity (n = 57) while English versions of SS-QoL was used to assess construct validity (n = 51) of FHV. The FHV was re-administered on 53 of the participants at 7-day interval to assess test-retest reliability. Each scale was administered in random order to eliminate bias. Data were analysed using Spearman correlation, Cronbach’s alpha, Intra-class Correlation Coefficient (ICC), Independent t-test and One-way ANOVA at p < 0.05. Results The SS-QoL 2.0 was successfully cross-culturally adapted to Hausa. Participants’ mean overall score on SS-QoL 2.0 (145.30 ± 39.78) did not differ significantly from that of FHV (150.41 ± 40.45) p = 0.28. The mean domains score did not differ significantly except in self-care and work domains. There were weak to good correlations for 6 out of 8 similar domains on Hausa versions of SS-QoL and WHOQoL-BREF (r = 0.21–0.61; p = 0.001–0.006); and good to excellent correlations between Hausa and English versions of SS-QoL (r = 0.70–0.92; p = 0.001). The FHV showed high to excellent test-retest reliability (ICC = 0.86–0.99) and acceptable to excellent internal consistency (Cronbach’s α = 0.71–0.90). No significant gender differences were demonstrated for any domains of FHV and for most domains across age groups. Conclusion The FHV is valid and reliable. The scale is recommended for assessing health-related quality of life among Hausa stroke survivors.
