The development of the MACE work-family enrichment instrument

Abstract

Orientation: An instrument based on a theoretical model is necessary to measure the positive side of the work-family interface. Research purpose: To develop items for measurement of work-family enrichment based on the elements contained within a theoretical model and to evaluate the latent trait functioning of these items. Motivation for the study: Major limitations exist regarding the conceptualisation and scale development of the positive side of the work-family interface. Research design, approach, and method: A quantitative research approach using scale development procedures was employed to develop the 95-item instrument. A cross-sectional survey design was used to collect data randomly from selected employees; data were processed using Rasch analysis. Main findings: The five-category scale works well for the most part, although a four-category scale could be considered. Thirty-five items either over-fitted or under-fitted the workfamily enrichment model. Person ability was measured in the low to middle ranges of workfamily enrichment. Participants' experience of work-family enrichment could be represented accurately. Sub-scale items displayed misfit, bias or both. Practical/managerial implications: The developed instrument can be investigated further to identify work-family enrichment factors that can measure workers' experience of enrichment in their work and family domains. Contribution/value-add: This study furthers theory building and empirical research in industrial psychology, by developing a new theory-based measuring instrument for the positive side of the work-family interface in the South African context. This study expanded on the model proposed by Greenhaus and Powell, by including all five categories of resources gains. Furthermore, the total of the resources was diversified, since some of the content of these resources encompasses multiple meanings
