Although coach burnout has been studied for 30 years, what measure to use in this context has not yet been problematized. This study focuses on evaluating convergent and discriminant validity of three coach burnout measures by using multi-trait/multi-method analysis (CT-C[M-1]) model. We choose Maslach Burnout Inventory (MBI), the two dimensional Oldenburg Burnout Inventory (OLBI), and a coach version of Athlete Burnout Questionnaire (CBQ). Our analysis shows that MBI and OLBI cover similar definitions of exhaustion and depersonalization/disengagement and that CBQ measures somewhat different dimensions. A problem for OLBI is a lack of discriminant validity due to high correlations between exhaustion and disengagement. For lack of personal accomplishment/reduced sense of accomplishment CBQ measures a somewhat different construct than MBI. Although all three measures have advantages and disadvantages, we promote CBQ since it discriminates between dimensions and covers important aspects of burnout in a sports context that the other two do not cover.
