Psychometric Properties of the Psychotherapy Expectancy Inventory-Revised (PEI-R)

The Psychotherapy Expectancy Inventory-Revised (PEI-R) was developed to measure clients' expectations of behavior in counseling. An exploratory factor analysis of the original PEI-R (Rickers-Ovsiankina, Berzins, Geller, & Rogers, 1971) on a sample of clients yielded four factors: approval, advice, audience and relationship (Berzins, 1971). The aim of the study presented in this paper is to examine the internal construct validity of the PEI-R by means of a confirmatory factor analysis on data gathered in a sample of 159 clients. The analysis revealed an adequate model fit for the four-dimensional oblique model. However, detailed inspection of model fit suggest the possibility of a fifth factor. Data concerning the reliability and the relationship with demographics are also provided.
