![The graphic representation of two models tested by the confirmatory factor analysis: A) MODEL 1 is the correlated trait–correlated uniqueness model with IVI, EVI, and KI all as separate factors and B) MODEL 2 is the correlated trait–correlated uniqueness model with EVI and IVI perspectives as one factor and KI as another. The numbers in the rectangles represent the number of items in the questionnaire, and in the ellipses are the names of the factors. Best model fits were achieved with Model 1 [three-factor model with IVI, EVI and KI all as separate factors].](https://sciendo-parsed.s3.eu-central-1.amazonaws.com/647385e34e662f30ba540b88/j_sjph-2018-0025_fig_001.jpg?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20240601T220449Z&X-Amz-SignedHeaders=host&X-Amz-Expires=18000&X-Amz-Credential=AKIA6AP2G7AKP25APDM2%2F20240601%2Feu-central-1%2Fs3%2Faws4_request&X-Amz-Signature=cd40afda29118c8174d921e6abadecf81af63869aadb3406fe3a45e95d8216ef)
