Abstract

Background: The Personal Wellbeing Index-Adults (PWI-A) is the most widely used instrument for measuring subjective-Quality of life (QoL). The current study seeks to investigate the construct Validity and Reliability of the Arabic version of the PWI-A on adults with bilateral hearing impairment by comparing the single-factor solution with the two-factor solution. Methods: A cross-sectional study was conducted at the Audio-Vestibular Medicine Unit of Alexandria University from July-2017 to January-2018. A total of 205 adults were interviewed to measure the subjective-QoL using the PWI-A instrument. Internal consistency was determined using both Cronbach’ s alpha and composite Reliability (CR). Validity was assessed by construct Validity, including ordinal regression, ordinal exploratory factor analysis (OEFA), and ordinal confirmatory factor analysis (OCFA). Results: The first four items of the PWI-A which are: satisfaction with living standard, health, achievements, and relationships were the most important indicators of subjective-wellbeing (Part r2 0. 0547, 0. 0324, 0. 0361, and 0. 0225, respectively). OEFA suggested that the two-factor model contributes better than the single-factor model. OCFA validated this suggested solution; (two-factor: RMSEA = 0. 084 (90% CI = 0. 01-0. 14); CFI = 0. 964; AIC = 52. 64; single-factor: RMSEA = 0. 119 (90% CI = 0. 07-0. 17); CFI = 0. 922; AIC = 62. 77). Good internal consistency was also presented (two-factor: Cronbach’ s alpha = 0. 719, 0. 693; single-factor: Cronbach’ s alpha = 0. 750). Conclusion: The Arabic version of the PWI-A is a multidimensional scale that consists of two dimensions: the first is related to subjective-QoL, and the second is related to satisfaction with the community. Thus, it is recommended to use the short version of the PWI-A with only four items to measure subjective-QoL, as it achieved sufficient Reliability and construct Validity.
