Psychometric evaluation of the Chinese version of the Questionnaire on Teacher Interaction (C-QTI) in Hong Kong

This study validated the Chinese version of the Questionnaire on Teacher Interaction (C-QTI) with two samples (ns = 370 and 369) of primary school students in Hong Kong. The 48-item measure had acceptable internal consistency reliability, but the reliability coefficients of four of the scales were too low. The findings supported the validity of the circumplex model underlying the instrument and verified the ability of the measure to differentiate between students' perceptions in different classes. With the refinement of the measure based on reliability analysis and Principal Components Analysis, Confirmatory Factor Analysis was conducted on the 35-item instrument to test its hypothesized factor structure. Findings on model fit indices were mixed, lending some support to the eight-factor structure of the questionnaire.
