Abstract
Introductionavailability of the Stroke-Specific Quality of Life scale 2.0 (SS-QoL(E)) in Yoruba and Hausa, two of the three major indigenous languages in Nigeria have the potential to promote its uptake among these population, however, its non-availability in the Igbo languages makes its use restrictive among the south-eastern Nigerians. This study was aimed at cross-culturally adapting and assessing validity and reliability of the Igbo version of the SS-QoL.Methodsthe SS-QoL(E) was cross-culturally adapted to Igbo following the American Association of Orthopaedic Surgeons’ guideline. This involved forward and back-translations, expert committee review, pretesting and cognitive debriefing interview to produce the final Igbo version, SS-QoL(I). The validity and reliability test involved 50 consenting Igbo stroke survivors. The construct validity was assessed by administering SS-QoL(E) and SS-QoL(I) on all 50 respondents, while SS-QoL(I) was re-administered at 7-day interval to assess test-retest reliability. Each scale was administered in random order. Data were analysed using Spearman’s correlation, Wilcoxon’s signed-rank test, Cronbach’s alpha, Intra-class Correlation Coefficient (ICC), independent t-test and one-way ANOVA at p<0.05.Resultsrespondents’ domains scores on SS-QoL(E) and SS-QoL(I) did not differ significantly except in mobility and work (r=0.58 to 0.87; p=0.001). Cronbach’s alpha was 0.69 to 0.87 for domains scores. The ICC ranged from 0.48 to 0.84, while no significant differences was found across different age groups or gender for the domains or overall scores of SS-QoL(I).Conclusionthe Igbo version of the SS-QoL has limited alterations from the original version and has moderate to excellent validity and reliability values.
Highlights
Surviving a stroke, the second leading cause of death and a major cause of disability worldwide, can be a long-term process that affects many aspects of a person’s life [1,2]
Stroke survivors (SSV) usually lose functionality and in Nigerian Africans, stroke impairs all facets of health-related quality of life (HRQoL) in domains such as social, emotional, cognitive, physical and economic rendering them as burdens to their families and communities [7]
Cross-cultural adaptation of SS-QoL 2.0 into Igbo language: the English Version of SS-QoL 2.0 was taken through forward translation to Igbo language by two independent bilingual translators following the guidelines of American Association of Orthopaedic Surgeons (AAOS) [25]
Summary
The second leading cause of death and a major cause of disability worldwide, can be a long-term process that affects many aspects of a person’s life [1,2]. In the West African sub-region, stroke is the leading cause of adult neurological admissions and accounted for 65% of such admissions [4,5]. In Nigeria, stroke is responsible for 0.9%-4% of total hospital admissions and 5%-45% of neurological admissions [6]. The more the severity of a stroke, the higher the disability and the lower the QoL of the SSV [8,9]. Stroke has detrimental effects on both short and long-term HRQoL of the SSV while disability resulting from stroke is a strong determinant of HRQoL [10,11]
