The impact of sport on children’s character, or their moral reasoning, may be influenced by the motivational climate established by significant adults (Miller et al., 1997; Tod & Hodge, 2001); however, only indirect evidence exists for such a relationship. Research has shown a relationship between motivational climate and goal orientations (e.g., White, 1996; Xiang & Lee, 2002), and between goal orientations and the degree to which one legitimizes injurious acts (Duda et. al 1991, Kavusanu & Roberts, 2001). The purpose of the present study was to examine the relationships among motivational climate, goal orientations, and moral reasoning. It was predicted that a performance climate would predict an ego orientation, a mastery climate would predict a task orientation, and higher ego orientation would relate to greater legitimacy of injurious acts in sport contexts. Young (M_age = 11.40; SD = 1.47) males (n = 69) and females (n = 79) participating in a National Youth Sport Program completed a survey assessing goal orientations (modified POSQ; Roberts & Balague, 1999), motivational climate (modified PMCSQ-2; Newton et al., 2001), and the legitimacy of injurious acts (modified CLIA; Bredemeier, 1982). Exploratory factor analyses provided evidence for factorial validity and Cronbach alpha coefficients revealed adequate internal consistency for each construct. A series of regression analyses were used to examine the relationships among the variables. The results of the first two regression analyses revealed that motivational climate predicted approximately 39% of the variance in task orientation (R = .63; F_{(2, 140)} = 46.27; p < .05) and 18% of the variance in ego orientation (R = .43; F_{(2, 141)} = 15.61; p < .05). Mastery climate was positively related to task (b = .63) and ego (b = .15), and performance (b = .38) climate was positively related to ego orientation. The final regression analysis revealed that goal orientations predicted approximately 15% of the variance in the perceived legitimacy of injurious acts (R = .39; F_{(2, 144)} = 12.59; p < .05) with task negatively relating (b = .15) and ego positively relating to (b = .38) perceived legitimacy of injurious acts. These results indicate that the direct relationship between motivational climate and moral reasoning found in previous research may be mediated by goal orientations. These results also provide additional support for the recommendation that teachers and coaches strive to create a mastery climate and foster a task goal orientation.
