Latent structure of the social interaction self-statement test: An application of hierarchical confirmatory factor analysis

Since the Social Interaction Self-statement Test was presented, a clear factor structure of the measure has not been defined. This situation is largely due to a lack of agreement among researchers with respect to the method of factoring, rotation criteria, and interpretation of factor loadings. The aim of the present study was to evaluate, using confirmatory factor analyses, the various factor models of the test. Results clearly supported a novel second-order factor model, which was developed by combining the current two- and five-factor models.
