Abstract

OBJECTIVE: Constructs capturing health or functioning can have reflective and/or formative measurement models. Although a construct's measurement model has extensive implications on the construction, validation and use of a measurement instrument, measurement models are frequently wrongly or not explicitly specified. As this is likely due to a lack of guidelines, this study uses sustainable employability as an example to demonstrate a) the applicability of an adapted checklist for establishing a construct's measurement model; and b) the use of structural equation modelling to handle formative constructs.

STUDY DESIGN AND SETTING: First, the checklist is applied to sustainable employability to establish its measurement model. Second, using observational self-report data from 2,544 employees, structural equation models are estimated to evaluate the structural and criterion validity of sustainable employability as a formative construct.

RESULTS: The checklist demonstrates strong applicability, identifying sustainable employability as a formative construct. Model fit indices (CFIs > .932, TLIs > .925, RMSEAs < .034) suggest the formative measurement model for sustainable employability is valid.

CONCLUSION: The checklist and structural equation modelling facilitate handling formative constructs. By establishing sustainable employability as a formative construct, individuals' long term ability to function at work can be more adequately studied and intervened upon.
