Cross validation of the Hypnotic Induction Profile factor structure: simultaneous confirmatory factor analysis of two published samples.
Abstract
This study cross-validated factor structure and psychometric characteristics of the Hypnotic Induction Profile (HIP). Earlier studies identified two constructs of the HIP, but their methodology did not allow empirical confirmation of the number of factors. I have used a new methodology, confirmatory factor analysis, and submitted the data from the previous studies to a simultaneous, multisample, factor analysis. The results showed that the HIP indeed consists of two factors. Although the HIP two-factor model is statistically adequate, 7 of the 10 scales have very low item reliability. Issues of measurement error and clinical implications of the study are also discussed in relation to the current findings.
