Psychometric Properties of the Interpersonal Styles Questionnaire for Physical Education in a Mexican Sample

During physical education classes, one of the contextual factors that can influence motivation is the teacher’s interpersonal style. The aim of this study was to analyze the psychometric properties, structure, and factorial invariance across gender of the physical education teachers’ Interpersonal Styles Questionnaire of Sonora, Mexico. The participants were 500 students (50.8% boys, 49.2% girls) aged between 9 and 13 years old (mean age (M(age)) = 10.72; standard deviation (SD) = 0.74) from different elementary schools of Sonora, Mexico. In terms of measuring the teacher’s interpersonal styles, the short version of the Learning Climate Questionnaire was used to measure autonomy support, whereas the Teacher Controllingness Scale was used to measure controlling style. The results support the structure and factorial invariance across gender groups of the Mexican version of the Interpersonal Styles Questionnaire for Physical Education (Cuestionario de Estilos Interpersonales en la Educación Física (CEI-EF, by its initials in Spanish)). In conclusion, the CEI-EF is a valid and reliable instrument that can be used to assess the teachers’ interpersonal styles and draw comparisons between groups of boys and girls.
