Abstract

The SERVQUAL can bridge the gap created by the paucity of client-report of quality of adolescent HIV care in LMIC. This study aimed to assess the psychometric properties of the SERVQUAL among adolescents in Nigeria. We used the SERVQUAL to obtain data from 212 adolescent s (aged 15 to 19 years) accessing HIV care in the southwest, Nigeria. We conducted exploratory factor analysis (EFA) to identify the underlying patterns in the instrument and confirmatory factor analysis (CFA) to validate our constructs, using the IBM SPSS and AMOS software, respectively. All the items loaded according to the original SERVQUAL except one item in the assurance domain, which was dropped due to poor factor loading (<0.4). The five factors contributed 63.60% of the variance. Upon CFA, the five-factor model had a good fit (Chi-square/df = 2.114, GFI = 0.909, CFI = 0.960, RMSEA = 0.073). All the retained factor loadings range from 0.67 to 0.86. The Cronbach’s ? for the five domains ranged from 0818 to 0.865, while composite reliability ranged from 0.820 to 0.878. All the average variance extracted (AVE) (from 0.646 to 0.696) were greater than 0.5. The square roots of all the AVE were greater than the correlation between the various constructs, indicating divergent validity. Responsiveness (0.51) had the greatest impact on satisfaction with HIV care services followed by reliability (0.39). The instrument demonstrated satisfactory reliability and validity, and good relationships with the participants’ overall rating of their satisfaction with HIV care services using the SERVQUAL
