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.

In dit onderzoek wordt het verband nagegaan tussen enerzijds initie¨le extreme voorkeursverschillen, de zogenaamde voorkeursincongruentie tussen clie¨nt en hulpverlener en anderzijds drop-out, tevredenheid en werkalliantie. De resultaten tonen aan dat clie¨nten die de behandeling vroegtijdig afbreken significant meer voorkeursincongruentie vertonen dan clie¨nten die de behandeling voortzetten. Ook blijkt de mate van voorkeursincongruentie significant negatief te correleren met de tevredenheid zoals beoordeeld door de hulpverleners. Dat wil zeggen: hoe groter de initie¨le voorkeursincongruentie, hoe ontevredener de therapeut is. De uitkomsten van dit onderzoek onderstrepen het belang van voorkeuren van clie¨nt en hulpverlener. De suggestie die eruit spreekt is dat bij de indicatiestelling voor psychotherapie rekening gehouden dient te worden met extreme voorkeursverschillen.

Since psychotherapy failures and early dropouts represent a sizable percentage of the clients who start psychotherapy, it is clearly important to devise a methodologically sound and effective process of treatment selection. In this study, a negotiation approach to treatment selection is proposed and situated in the context of an integrative viewpoint on psychotherapy. The preferences of the client, the client's control of the situation of choice, and the compatibility of differing views of client and therapist constitute the typical characteristics of this negotiation approach. The first part of this study gives a careful description of the negotiation approach. The second part examines the influence of the negotiation approach on the dropout rate and on initial therapeutical contacts. Results indicate a significant effect of negotiation on dropout, suggesting that clients who perceive treatment selection as a negotiation process are more successful in their initial therapeutical contacts.
