Factorial validity of the organizational health inventory among Omani teachers: Invariance across gender: Invariance across gender

This study examined the factor structure of the Organizational Health
Inventory (OHI) scale among Omani teachers. There were four factors
assumed to represent the OHI (principal influence, academic emphasis,
morale, and initiating integrity). Testing the scale reliability was another aim
of this study. A random sample (n=458) of Omani teachers was considered.
The short version of the scale has 30 items. Exploratory and confirmatory
factor analysis was performed on the sample data. The model is good fitted
to the data. Across gender, the invariance of the structure was tested, and the
parameters of the model were invariant. Consequently, the two genders were
compared via multivariate analysis of variance (MANOVA) with gender as
an independent variable and subscales. The female teachers were found to
more likely show principal influence, academic emphasis, and morale than
the male teachers, who instead, were more efficacious than the female
teachers in dealing with institutional integrity.
