El principal objetivo del estudio fue examinar perfiles de padres respecto a la presión/implicación y apoyo a las necesidades psicológicas básicas (NPB) sobre la motivación y aburrimiento desarrollado por jóvenes deportistas. La muestra estuvo formada por 301 padres y sus respectivos 301 hijos (M = 13.92; DT = 2.04), quiénes pertenecían a deportes colectivos (n = 191) e individuales (n = 128). Se midieron en padres la percepción de implicación y presión, al igual que el apoyo a las NPB, mientras que la motivación autodeterminada y el aburrimiento en la práctica fueron variables valoradas en adolescentes. Los resultados muestran la existencia de dos perfiles (perfil adaptativo, que estaba compuesto por el apoyo a las NPB y bajos niveles de presión, y perfil desadaptativo, que estaba formado por altos niveles de presión y bajos valores de apoyo a las NPB), y una relación entre el perfil desataptativo de los padres y la motivación de los niños y su aburrimiento en la práctica. Asimismo, se demostró que los padres con un perfil adaptativo realizaban menos actividad física durante la semana. Para concluir, se destaca la importancia de que los padres generen bajos niveles de presión y alta implicación en la práctica deportiva de sus hijos, así como promover el apoyo a las NPB, así como incrementar sus niveles de actividad física, con el objetivo de mejorar la motivación de los jóvenes deportistas y descender los niveles de aburrimiento en la práctica.

The main aim of the study was to examine parents´ profiles respecting pressure/involvement and support to the basic psychological needs (BPN) on motivation and boredom developed by youth participants in sport practice. The sample was formed by 301 parents and their respective 301 children (M = 13.92; SD = 2.04), who belonged to team sports (n = 191) and individual sports (n = 128). Perception of involvement and pressure, as well as support to the BPN were measure in parents, whereas self-determined motivation and boredom in the practice were variables assessed in adolescents. Results showed the existence of two profiles (adaptive profile, which was composed of support to the BPN and low levels of pressure, and maladaptive profile, which was formed by high level of pressure and low levels of support to the BPN), and a relationship between parents´ maladaptive profile and children´s motivation and boredom. Moreover, it was revealed that parents with a lower adaptive profile showed less physical activity during the week. To conclude, it is highlighted the importance to create a lower pressure and greater involvement in the adequate practice of their children, as well as promote support to the BPN, and increase their level of physical activity, with the aim to enhance youth athletes’ motivation and decrease their boredom levels in the practice.

Este trabalho teve como objetivo analisar as propriedades psicométricas do Questionário de Apoio às Necessidades Psicológicas Básicas (QANPB) com estudantes portugueses. A amostra foi constituída por 445 estudantes do sexo masculino e feminino, com idades compreendidas entre os 12 e os 16 anos. Inicialmente, a escala foi traduzida para o português, para posteriormente se realizar uma análise das propriedades psicométricas. Os resultados comprovaram que o QANPB se apresentava como um instrumento com evidências de validade (fatorial e nomológica) e confiabilidade, que permite analisar a percepção dos alunos sobre o apoio do professor à autonomia, competência e relações sociais nas aulas de Educação Física.

The purpose of this study was to analyze the psychometric properties of the Basic Psychological Needs Questionnaire (BPNQ) with Portuguese students. The sample was composed of 445 male and female students, ranging in age from 12 to 16 years. Initially, the scale was translated into Portuguese, and later, an analysis of the psychometric properties was done. Results emphasized that the BPNQ is a valid (factorial and nomological) and reliable instrument to measure students' perception of autonomy, competence and relatedness support in Physical Education classes.
