Construct validity: Basic Psychological Needs Scale for Teachers
Keywords:Teacher autonomy, pedagogical competence, peer relatedness, scale validity, selfdetermination theory.
Teacher autonomy encompasses pedagogical activities oriented towards planning, instruction, and
assessment, as well as administrative tasks required by the education system. Therefore, it is imperative
to focus research on teacher autonomy in specific tasks, using data collection procedures suitable to the
context. In this study, the aim is to validate an original scale for collecting data on teacher autonomy in
classroom settings under criteria established by Self-Determination Theory, in the framework of basic
psychological needs. The method comprises a nonexperimental quantitative design, using a random
cluster sample that is understood as a probability sampling because participant teachers only work in
primary education levels. Results demonstrate that the scale possesses a strong degree of robustness
regarding construction, application, and data collection. In conclusion, the validated scale identifies
teacher autonomy as an explanatory variable in the model.
