The study of confirmatory factor analysis and internal consistency of the Nature Relatedness Scale in students

Abstract

The purpose of the study was to examine the validity and reliability of The Nature Relatedness Scale (NR- scale) by analyzing the responses made to it by 300 students from agriculture faculty of Tabriz University. The confirmatory analyses were used to compute the validity. The goodness of fit for each model was assessed using the Satorra–Bentler scaled chi-square, the Incremental Fit Index (IFI), and the Comparative Fit Index (CFI). A non-significant chi-square, and values greater than 0.90 for the GFI, IFI and CFI, are considered to reflect acceptable model fit. The internal consistency was used to determine reliability of NR- Scale. Confirmatory factor analysis revealed that the three-factor model of NR- scale demonstrated a superior fit to the data. The Cronbach alpha values showed that NR-Scale has a good reliability. The results buttressed the notion that the NR- scale is a valid and reliable measurement instrument in predicting environmentally responsible behavior (ERB)
