Factorial invariance of the 13-item Sense of Coherence scale across gender.

This study examined the gender invariance of the 13-item Sense of Coherence (SOC) scale. Confirmatory factor analyses indicated that a single factor model with one pair of correlated errors fit the data well. Invariance testing indicated that the scale is both congeneric and tau equivalent, meaning that a single latent SOC construct holds equally well for males and females, and that both genders demonstrate an equivalent pattern of factor loadings. There was little evidence in support of latent factor mean equivalence across gender. Explanations for the lack of factor mean equivalence were discussed and recommendations for future research were suggested.
