This paper reports research that engaged in the evaluation of an intervention programme designed to enhance the employability of a group of unemployed graduates. The evaluation adopted a quasi-experimental intervention research method employing a general self-efficacy scale, which had been validated in prior research. Results revealed that participants displayed higher levels of GSE after engagement in the programme. Results also revealed the effect of "behavioural plasticity" on the intervention experiences of unemployed graduate participants. The findings of this study are discussed in relation to programme design, recruitment and evaluation.
