A theory-driven evaluation of a wellness initiative

Abstract

Orientation: By reporting on an evaluation of a wellness initiative, this article brings together an element of organisational development (employee wellness) with an approach to programme evaluation (programme theory-driven evaluation).

Research purpose: Two questions were addressed: ‘What is the causal logic of the wellness initiative?’ and ‘Is this a plausible programme theory according to social science research and literature?’

Motivation for the study: A study that could demonstrate the usefulness of the theory-driven evaluation approach, especially in the local human resource (HR) domain, was considered to be valuable. In addition, this evaluation provided a careful consideration of how plausible it is for such interventions to achieve what they set out to do.

Research design, approach and method: The evaluation relied mainly on qualitative methods (the examination of secondary data and interviewing) to extract programme theory, and on literature to assess plausibility.

Main findings: The study had two main outcomes: the finalisation of a model of how the programme is supposed to work according to programme staff, and the conclusion that the model is plausible, provided it is implemented at full strength.

Practical/managerial implications: Programme staff are advised to pay particular attention to implementation fidelity, especially to employee participation and involvement in the programme’s activities. A number of strategies are recommended to strengthen the effect of the model.

Contribution/value-add: This evaluation showed the importance of conducting a theory- driven evaluation, not only in order to understand the programme and its context, but also to provide a basis for an implementation and outcome evaluation.
