The results showed content validity index (CVI) score were 0.80-1.00 and 0.90 for item and scale, respectively. The correlation among items indicated moderate association (r = 0.255-0.581). The EFA resulted in the KMO 0.633, Bartlett test 310.604, p = 0.000, and total variance of explained QoL was 64.22%.
