The purpose of the study was to examine the relationship between perceptions of psychological climate in ice hockey players and self-reported effort. A modified version of the Psychological Climate Questionnaire (Brown & Leigh, 1996) and a measure of self-reported effort were given to 160 players from 8 teams during the last week of the regular schedule. Given the hierarchical nature of the data, multilevel modeling was used to examine the relationship between perceived effort and 5 subscales of psychological climate (Role Clarity, Contribution, Supportive Management, Challenge, and Self-Expression). Two of the subscales (Role Clarity and Self-Expression) significantly predicted perceived effort (ps <.01). Overall, 18% of the variance in perceived effort was accounted for by climate. These findings provide preliminary support for the idea that the psychological meaning that individuals associate with various aspects of their team environment are linked to the effort an athlete reports exerting over a season.
