Abstract：
:The aim of this study was to integrate both dispositional and situational factors to examine their interactive ability to predict pre-competitive goal states of task and ego involvement in a sample of National junior tennis players. The Task and Ego Orientation in Sport Questionnaire (Chi and Duda, 1995) and a set of single-item assessments of match goal orientation represented the dispositional measures in the study. These were administered at home, away from the tennis environment. The situational antecedents of pre-match task and ego involvement were assessed by an 11-item Match Context Questionnaire, which was administered to the players (n = 119) within 1 h of their singles match start time at the National Junior Championships. The Match Context Questionnaire also measured the personal task- and ego-involved goal states of the player with respect to the upcoming singles match (i.e. 'state' goals). Factor analysis of this questionnaire revealed three situational factors which cumulatively accounted for 64.7% of variance in the match context: social/personal perceptions of ability; perceived state goal preference of significant others; and match value. Moderated hierarchical regression analyses revealed significant main effects of the dispositional and situational factors on the different goal types. Specifically, perceptions of significant others, the achievement value of the match and perceptions of ability were the major predictors of task involvement. The pre-match intensity of ego involvement was predicted by ego orientation combining with perceptions of significant others and match value. These findings reinforce the need for researchers to consider the importance of both dispositional and situational variables when predicting goal involvement in competitive contexts.
