Determined if preferences of athletes for training and instruction (task-oriented) behavior and social support (relationship-oriented) behavior would vary with athletic maturity (operationalized in terms of level of competition). Basketball players from high school midget (
n = 67), junior (
n = 63), and senior (
n = 63) divisions and a university (
n = 69) completed a preferred leader behavior scale for sports. Analyses revealed a quadratic trend in preference for training and instruction that progressively decreased from high school midget through junior to senior levels and increased at the university level; however, the direction of this trend was opposite to that predicted. A linear trend was obtained for social support, which progressively increased from the high school midget level to the university level but, again, in a direction opposite than that predicted. It is noted that future research should incorporate both a wide range of competition levels and groups with markedly different levels of success to determine the interrelationship between leadership preference and athletic maturity. It is also noted, however, that sport as a social system may not afford athletes an opportunity to achieve athletic maturity. (30 ref) (PsycINFO Database Record (c) 2012 APA, all rights reserved)
