AbstractThe Mastery Performance‐Goal Orientation Test (MP‐GOT) assesses performance‐ and mastery‐orientation along a single bipolar dimension. In Study 1 (n = 198) we explored its psychometric properties and determined whether its results were related to learning. In addition, we employed Latent Profile Analysis to explore goal orientation profiles. In Study 2 (n = 1689) we explored whether goal orientation scores were related to cooperation and whether the goal orientation profiles identified in Study 1 were replicated. In both studies, reliability of the MP‐GOT was high, and a 4‐profile solution was retained. Mastery‐oriented participants tend to obtain higher learning scores (Study 1) and higher cooperation scores (Study 2). MP‐GOT has the potential to be a useful instrument for measuring goal orientation and its relation to relevant behavioral outcomes.
