The ability to improve creative problem solving (CPS) is considered to be an important resource in a variety of fields such as education (see Murdock, 2003) and business (see Thompson, 2003). Previous research suggests that interventions aimed at training people to improve their CPS skills can be effective, however it is not always clear what tools are being used and it is sometimes difficult to untangle the effect the different tools are having (see Vernon, Hocking, & Tyler, 2016, for a review). This study therefore aimed to utilise an empirically- based creativity toolkit in an 8 week training program aimed at enhancing students' CPS skills. The intervention group was comprised of 33 psychology students who signed up to undertake 8 weeks of CPS training and the control group (n = 9) were matched for contact time, undertaking 8 weeks of cognitive psychology lectures instead. In week 1 (Time 1) and week 8 (Time 2) all participants were assessed using two Unusual Uses Tasks (UUT) and a Creative Problem Solving (CPS) task and were also asked to fill out measures of creative self-efficacy. Analyses revealed that whilst the control group showed no improvement on any of the measures from Time 1 to Time 2, the intervention group showed a significant increase in both their creative self-efficacy and also their levels of creativity on both the UUT and CPS tasks. Whilst a follow- up study utilising a larger control group is ideally needed, these preliminary findings nonetheless support the use of this empirically based creativity toolkit for enhancing creativity problem solving skills
