Abstract
Abstract Background This cross-sectional study aimed to assess the socio-demographic, anthropometric, and patient characteristics of 94 Yoruba speakers aged 60 years and older, and to validate the Yoruba version of the Clinical Frailty Scale (CFS). Methods This study used a cross-sectional design with a purposive sampling technique and a sample size of 94 participants. This study also made use of the World Health Organisation methodologic guidelines on cultural adaptation of clinical scales. Convergent validity was assessed by evaluating the context that the Clinical frailty scale (CFS) relates to the Edmonton frailty scale, using the Spearman rank correlation coefficient. The known group validity was assessed using one-way ANOVA. Results The mean age of participants was 70.81 ± 8.11 years, with a mean BMI of 27.04 ± 5.61. The cohort included 38 males (44.4%) and 56 females (59.6%). Educational attainment varied, with 20.2% having no education and 9.6% holding postgraduate degrees. The validated CFS has excellent content validity (S-CVI/AVE = 0.96; S-CVI-UA = 0.78). Convergent validity demonstrated a moderate correlation between the CFS and the Edmonton Frail Scale (Spearman’s rho = 0.61, p < 0.01). Known-group validity indicated significant associations between frailty, age (p = 0.02), and BMI (p = 0.007). Conclusion The Yoruba version of the CFS is a valid tool for assessing frailty in elderly Yoruba-speaking populations.
