Factor Structure, Reliability and Measurement Invariance of the Psychological Capital Questionnaire for Iranian Male and Female Teachers

The main purpose of the present study was to investigate psychometric properties of the Farsi version of the Psychological Capital Questionnaire (PCQ, Endler & Parker, 2007) among male and female teachers. In this correlational study, 381 teachers completed the (PCQ) and Teacher Emotion Inventory (TEI, Chen, 2016). The confirmatory factor analysis and multi-group methods were used to compute the PCQ's factorial validity and its gender invariance, respectively. The results of confirmatory factor analysis based on AMOS software showed that the four factor model of PCQ (self-efficacy, resiliency, optimism and hope) fit well to the data across two groups. The results of multi-group confirmatory factor analysis revealed the cross-group invariance of factorial structure, factor loadings, and factor variances and covariances of the PCQ across teachers. Internal consistency coefficients for the four subscales were 0/87, 0/83, 0/86 & 0/70 respectively. In sum, these findings approved the validity and reliability of the PCQ to measure the psychological capital as a broad, compound and higher-order construct and has a buffering function against stressors in male and female teachers.
