This research work aims to analyze the psychometric properties of the Basic Psychological Needs Satisfaction and Frustration Scale (BPNSFS) -autonomy, competence and relatedness- identified by the self-determination theory (Deci & Ryan, 2000b), in a sample of 297 university students from different faculties and programs belonging to a Chilean university. To achieve the objective, through a psychometric study by confirmatory procedures, a confirmatory factor analysis (CFA) was performed, analyzing the six-factor proposal developed by Chen et al. (2015), and the internal consistency of the scale was evaluated using the ordinal Alpha. The outcomes obtained from the sample of university students indicate a good internal consistency, Alpha = 0.90 and 0.86 for psychological needs satisfaction and frustration. Besides, the outcomes of the confirmatory factor analysis showed an adequate fit of the model (χ²/gl = 1.75; CFI = 0.92; IFI = 0.92; TLI = 0.90; RMSEA = .05 and SRMR =.05) to the data, showing evidences of the validity of the six-factor structure proposed. According to the foregoing, it is considered that the scale to measure satisfaction and frustration of the three basic psychological needs can be used initially in university students in the higher education of Chile, thus, allowing the relationship with other variables of interest to generate explanatory models that allow going in depth the understanding of aspects that are of institutional interest.

La presente investigación tiene como propósito analizar las propiedades psicométricas de la Escala de Satisfacción y Frustración de las Necesidades Psicológicas Básicas de Autonomía, Competencia y Relación (ESFNPB) identificadas por la teoría de la autodeterminación (Deci & Ryan, 2000b), en una muestra de 297 estudiantes universitarios de distintas facultades y carreras pertenecientes a una universidad Chilena. Para lograr el objetivo, mediante un estudio psicométrico por procedimientos confirmatorios, se realizó un análisis factorial confirmatorio (AFC), analizando la propuesta de seis factores realizada por Chen et al. (2015) y se evaluó la consistencia interna de la escala mediante el Alfa ordinal. Los resultados obtenidos con la muestra de estudiantes universitarios indican una buena consistencia interna, alfa = 0.90 y 0.86 para satisfacción y frustración de las necesidades psicológicas, así mismo los resultados del análisis factorial confirmatorio mostraron un ajuste adecuado del modelo a los datos (χ²/gl = 1.75; CFI = 0.92; IFI = 0.92; TLI = 0.90; RMSEA = .05 y SRMR =.05), brindando evidencias de validez de la estructura de seis factores. Según lo anterior se considera que la escala para medir satisfacción y frustración de las tres necesidades psicológicas básicas puede ser utilizada preliminarmente en estudiantes universitarios en el contexto de la educación superior chilena, permitiendo también la relación con otras variables de interés para generar modelos explicativos que permitan profundizar la comprensión de aspectos que son de interés institucional.
