Measuring the Immeasurable: the Perceived Coaching Effectiveness Scale

This paper presents the perceived coaching effectiveness scale (PCE) which was developed in response to the lack of an adequately rigorous, reliable and valid measure of coaching outcomes from the coachees perspective. Scale development procedures as outlined by Hinkin (1998) and DeVillis (2012) were followed. Based on the literature, five themes of perceived coaching effectiveness were identified. In-depth interviews resulted in 110 potential items being generated. After questionnaire administration (n = 201) and factor analysis, three higher order factors and nine lower order factors were confirmed and the scale was reduced to 27 items. The findings and implications for practice are discussed.
