This research study took place at the High Performance Centre (hpc) at the University of Pretoria (UP) in South Africa (SA). The sport psychologists/sports counselors at the hpc mainly deliver performance development services to the athletes. The sport psychology services at the hpc are conducted to the athletes via the Psychological Skills Training (PST) approach and Mindfulness-Acceptance-Commitment (MAC) approach. These two approaches are individualistic in nature and the aim of my study was to move away from a more traditional individualistic perspective to an ecological perspective that takes into consideration other role players such as sport scientists. This was achieved by developing a sport science specific MAC programme for the sport scientists, which was facilitated through experiential learning. The goal of the MAC programme was to explore the sport scientists’ experiences with reference to what they discovered and how they applied their learning. Eight in depth, semi-structured interviews were conducted with four sport scientists at the hpc after their participation in the programme. Interpretive Phenomenological Analysis (IPA) was used to analyse the semi-structured interviews. The findings were mainly related to difficulties and advantages that the sport scientists experienced when they applied the MAC principles. / Dissertation (MA)--University of Pretoria, 2016. / Psychology / MA / Unrestricted
