TESTING THE ASSUMPTIONS OF TAUEQUIVALENCE AND RELIABILITY ANALYSIS IN THE ACADEMIC EMOTION REGULATION QUESTIONNAIRE (AERQ) SUBSCALES

Dr. Vijay Kumar Chechi, Rajib Chakraborty.

Abstract
The researchers tested the assumptions of Tau-equivalence on the two Academic emotion
regulation questionnaire (AERQ) subscales Reappraisal and Suppression, developed by Buric, Soric and
Penezic (2016). The sample of the study comprised of 161 students (127 boys and 34 girls) from the School of
Hotel management, of Lovely Professional University, India. The data was tested for any violation of Tauequivalence assumptions and for homogeneity of the items of the two sub-scales using the R package
Coefficientalpha developed by Zhang and Yuang (2016). The result was non-significant for the test of tauequivalence of Reappraisal sub scale. The robust F-statistics during the test of tau-equivalence was 1.866 with p
value 0.061. However, significant result was obtained for the test of homogeneity of items of its sub-scale with
the robust F-statistics at 2.47 for p-value of 0.0348. The results of test of tau-equivalence and test of
homogeneity of items for sub-scale Suppression were non-significant. The robust F-statistics in the former case
was 0.939 with a p-value of 0.4929 and the same estimate for the test of homogeneity of items was 0.656 with a
p-value of 0.6571. Such results indicated that the sub-scale Suppression is more homogeneous (with factor
loadings 0.694, 0.696, 0.685, 0.676, 0.633) than the sub-scale Reappraisal (with factor loadings 0.745, 0.735,
0.731, 0.63 and 0.66). The non-robust, robust and confidence interval forms of “Cronbach’s alpha” and
“McDonald’s Omega”, along with the standard errors for Reappraisal and Suppression scales were estimated
and reported using Psych , GPArotation, alpha and Omega.res packages in RStudio 3.0 console. The reliability
estimates in the presence of outliers and non-normality of data were found to be sufficient for both the subscales of AERQ. “Raykov’s composite reliability” for congeneric scales was found to be at 0.829 and 0.81 for
reappraisal and suppression scale respectively. The ramifications of the study results are discussed.

Key words: Academic Emotion Regulation Questionnaire (AERQ), Cronbach’s alpha, McDonald’s Omega, Confidence Interval Alpha, Robust Alpha Coefficient, Robust Omega Coefficient, Tau-equivalence condition.
