Psychometric validation of the Brazilian version of the interpersonal behavior questionnaire in physical education Bordoni Caldeira, Hermê Fellipo Correia Júnior, Jânio Luiz Albuquerque da Costa, Julio Cezar dos Santos Ferreira, Giovana Pereira da Silva, Samara Cecília Sabino Pereira Gonçalves, Marina Burgueño, Rafael Freitas-Dias, Ricardo Ejercicio físico - Estudio y enseñanza Grounded on Self-Determination Theory, this study aimed to validate the internal structure and internal consistency of the Brazilian version of the Interpersonal Behavior Questionnaire in Physical Education (IBQ-PE-BRA) among Brazilian adolescents. A total of 500 students (51.2% female), aged 11–17 years (M = 13.82, SD = 1.77), completed the IBQ-PE-BRA. Confirmatory Factor Analysis supported the model’s adequacy, and additional Item Response Theory analyses identified items with insufficient discrimination, indicating a low ability to differentiate between different levels of the construct. The internal consistency measure was satisfactory for the Autonomy-Supportive Behaviors, Competence-Supportive Behaviors, and Relatedness-Supportive Behaviors factors. On the other hand, the three types of need-thwarting behavior obtained unsatisfactory scores. The results of the present study provide important insights for researchers and professionals who intend to use the IBQ-PE-BRA as a tool for assessing students’ perceptions of Physical Education teachers’ behaviors. 2026-02-24 journal article Caldeira, H.F.B., Correia Júnior, J.L., da Costa, J.C.A. et al.
