The present experiment was designed to examine the mediational role of self-handicapping in the relationship between achievement goals and performance on a sport based activity (i.e., a basketball dribbling task). The achievement goals of the trichotomous achievement goal framework were manipulated, behavioral and self-reported self-handicapping opportunities were provided, and performance attainment was assessed. Performance-avoidance goals led to worse performance and evoked higher levels of behavioral and self-reported self-handicapping than performance-approach and mastery goals. Both forms of self-handicapping were found to have independent mediational effects on decreased performance. Implications for the adoption of achievement goals and the use of self-handicapping strategies are discussed.
