Abstract

Using a published correlation matrix (T. Lawrence and P. DeCicco, 1997), the author re-evaluates the number of dimensions of paranormal belief supported by the revised Paranormal Belief Scale (PBS; J. Tobacyk, 1988). Two empirically validated procedures (the minimum average partial and parallel analysis criteria) are used to estimate the number of latent variables represented in this data set. Both indicate that, for these data, the 7-factor solution favored by Tobacyk and G. Milford (1983) and the 5-factor solution favored by Lawrence et al (1997) and Lawrence and DeCicco (1997) may represent overextractions. Instead, 4 latent variables may be all these data can support. It is suggested that numerous modifications should be made to the PBS before additional effort is expended on the factor structure of its items or on the relative merits of orthogonal and oblique rotation of its factors.
