- Abstract
The self-determination theory is one of the most popular theories on motivation. It postulates that three basic needs mediate humans' proactivity and involvement: autonomy, competence, and relatedness. Among the measurement instruments addressing these needs, the Balanced Measure of Psychological Needs (BMPN) has been recently presented. This research aims to study the dimensionality of the BMPN, in its Portuguese and Spanish versions. Samples of 2034 and 715 students were recruited from high school classes in Angola and the Dominican Republic, respectively. The better-fitting model for the Portuguese and Spanish versions of the BMPN scale was the one posing a method artifact. This evidence, together with lower factor loadings, problems with reliability, and poorer nomological validity for the negatively worded items, moved us to propose a positive version of the BMPN, with better psychometric properties. Our results support latest research criticism on the harmful effects of including negatively worded items in scale development.
