Burnout and work engagement of South African blue-collar workers: The development of a new scale

Abstract

Research in South Africa on work-related well-being (specifically burnout and work engagement) has focused mainly on white-collar workers. Although blue-collar workers form a major part of the South African work force, no valid and reliable instruments exist to measure burnout and work engagement of blue-collar workers. The objectives of this study were (1) to develop a work-related well-being scale that measures burnout and work engagement of blue-collar workers; (2) to test the newly developed items using Rasch analysis; and (3) to test the factorial validity and reliability of the new scale. A cross-sectional survey design was used in a convenience sample of blue-collar workers in different industries in South Africa (N=2769). Following scale development procedures, a scale was developed to measure burnout (exhaustion and cynicism) and work engagement(vigour and dedication). Using Rasch analyses, two items were eliminated, resulting in an 18-item instrument. Five items were retained to measure exhaustion, five items to measure cynicism, four items to measure vigour and four items to measure dedication. The results of the confirmatory factor analysis showed that a twofactor model with two higher-order factors – burnout (consisting of exhaustion and cynicism) and work engagement (consisting of vigour and dedication) – fit the data best. All the scales were reliable
