The objective of this research was to explore the psychological elements of workplace coaching. Specifically, the research aimed to consider the practices and processes of workplace coaching as an occupational psychological intervention. Using a mixed methods approach the two studies were conducted in parallel. The qualitative study focused on deepening our understanding of coaching as a process experienced by the coachee (the person receiving coaching). A grounded theory methodology was used based on a critical realist epistemology. The objective of the quantitative element of the study was to explore the reported behaviours used by coaches in their coaching practice. This study used a survey method to assess the variability in coaching styles between different reported coaching methodologies, psychologists and non-psychologists, gender and personality preferences as measured by MBTI. The themes extracted from the grounded theory study included the coachee expectations, properties of the session, attributes of the coach, behaviour's of the coach, behaviours of the coachee and outcomes. The statistical analysis produced largely non-significant results, with the exception of results relating to differences between coaches, the UK population and counsellors, based on the Myers Briggs Type Indicator. The findings were triangulated and used to inform the development of a framework for coaching which helps bring together the otherwise disparate aspects of workplace coaching into a single conceptual framework and which can constructively contribute towards an evidence based debate on coaching training and development
