Validation of the Teacher Emotion Inventory from primary school in Mashhad

Context: Emotions plays a major role in the educational environment so Scale to measure teachers emotions is noteworthy and significant subject.
aim: The aim of this research is to examine Validity and Reliability of TEI in Mashhad.
The research method was descriptive-correlative. The required sample size was determined 023 based on Cochran formula, and participants were selected by random Cluster method. The Teacher Emotion Inventory (TEI) of Chen (2016), positive and negative affect scale (PANAS; Watson, Clark and Tellegen) (1988) were completed by participants at the same time. Primary teachers were selected by multi-stage random sampling. Teacher Emotion Inventory and positive and negative scale were tested. The reliability of TEI was confirmed by internal consistency (Cochran`s alpha). The validity was determined by content validity, convergent validity, exploratory and confirmatory factor analysis.
Findings: Results showed that alpha coefficient for total size was 0/88 and for subscales was from 0/74 to 0/88. The correlation coefficient between Teacher Emotion Inventory and PANAS for convergent validity was 0/41. The analysis of principle components with Varimax Rotation showed that eigenvalue of 5 factors are considerable which explains 62/49 percent of the total variance. The goodness of fit indexes was confirmed by confirmatory factor analysis (CFA).
Hence, TEI has a good internal consistency and sufficient validity in the sample of Iranian teachers.
