The Task and Ego Orientation in Sport Questionnaire adapted for youth with intellectual disabilities (TEOSQ-ID)

The objective of the present study was to validate a version of the Task and Ego Orientation in Sport Questionnaire (TEOSQ) adapted for youth with intellectual disabilities (ID). A sample of 362 youth with mild to moderate ID (61.0% boys, M = 15.80 years) from Australia (N = 240) and Canada (N = 122) respectively completed English and French versions of the TEOSQ-ID twice over a one-year interval. Confirmatory factor analyses supported the validity and reliability of the a priori two-factor structure of the TEOSQ-ID, as well as the weak, strict, and latent variance-covariance invariance of this factor structure across linguistic versions. The results also supported the strong invariance of a majority of the TEOSQ-ID items across linguistic versions, and revealed latent mean differences showing that English-Australian youth tended to score lower on the TEOSQ-ID factors than French-Canadian respondents. The results also supported the measurement invariance of the TEOSQID over time, and revealed a lack of differential item functioning (i.e., measurement bias) as a function of youth's age, body-mass index, ID level, sex, and frequency of sport involvement. Meaningful latent mean level differences were observed on the TEOSQ-ID factors in relation to body-mass index, ID level, and frequency of sport involvement. Finally, our results supported the convergent validity of the ego and task factors in relation to a measure of perceived physical abilities.
