Purpose: Based on a sample of employees with disability, this study aimed to: (1) evaluate the construct validity of work ability index (WAI), core self-evaluation scale (CSES) and job in general index (JIG), in order to make a valid and reliable assessment of their work ability, job satisfaction and core self-evaluation; (2) assess their levels of work ability, job satisfaction, and core self-evaluation; (3) investigate the associations of work ability with job satisfaction and core self- evaluation among them; and, (4) determine which demographic characteristics significantly affect the work ability of employees with disability.
Methods: The sample consisted of 275 employees with disability. Data was collected using a self-administered survey.The analysis focussed on: (1) CFA- for evidence of the construct validity of the employed scales; (2) Descriptive analysis - for evaluating the variables of the study; (3) Pearson correlation analysis – for understanding the simple correlation between variables of the study; and, (4) One-way ANOVA- for identifying the demographic factors that influence the work ability of employees with disability.
Results: The findings indicated that 29.5% of the participants had poor levels of work ability, while 35.3% reported moderate levels of work ability. Also, 49.1% of the participants reported moderate levels of core self-evaluation, and 70.5% exhibited high job satisfaction. In this study, work ability was found to be associated with core self-evaluation and job satisfaction. Significant differences in work ability levels were found in terms of age, level of education and employment status of the respondents.
Conclusion: Work ability among employees with disabilities did not seem to be influenced merely by individual health status. Attitudinal and dispositional factors appeared to have a significant impact on their levels of work ability. Thepotential positive impact of education and employment status on employees’ levels of work ability are highlighted in this study.
