This research examined the differential utility of two alternative Theory of Planned Behaviour (TPB) models of behaviour to explain intentions to participate in counselling. Individuals (N = 259) employed in a front-line, at-risk occupation for the Irish government completed a TPB-based questionnaire. Quantitative analyses revealed that participants held positive-to-neutral intentions to participate in counselling, irrespective of gender. The original TPB model explained 47% of variance in intentions whereas an alternative TPB model, splitting the PBC construct between its internal and external control components, explained a further 10% of variance. Furthermore, self-efficacy was found to be the strongest predictor of intentions. This study therefore supports the use of the TPB in understanding counselling-seeking behaviour.
