The researchers developed the initial items used to create the Teaching Styles Questionnaire (TSQ) as a modification of the 60 most relevant items from the Parenting Styles and Dimensions Questionnaire (PSDQ; Robinson et. al, 1995). We used factor analyses to explore potential subscales and test the convergent validity of the Teaching Styles Questionnaire subscales. By using factor analyses, long and short versions of the Teaching Styles Questionnaire were developed, consisting of 27 and 16 items respectively. The model fit indices indicated both versions of the Teaching Styles Questionnaire have a good model fit. Criterion-related validity was supported by correlations with the Teachers’ Sense of Efficacy Scale (Tschannen-Moran & Hoy, 2001). Limitations to this study are discussed. (author abstract)
