Abstract

The latent structure of a Swedish version of Wallerstein’s Scales of Psychological Capacities (PSYCAP) was tried with confirmatory (CFA) and exploratory factor analyses (EFA), based on PSYCAP ratings for 207 patients with severe psychiatric disorder. As a first step, the original theoretical model with three types of capacity (capacity to relate to self, capacity to regulate self, and capacity to relate to others) was tried with a CFA. This model had a poor fit to the data, as estimated with a number of fit measures. PSYCAP data was then entered into an EFA, which suggested an alternative model with three factors. The fit-test of this model suggested that the fit was reasonable. The three factors of the alternative model were used to compute subscales, and a satisfying reliability was established. The subscales also demonstrated adequate ability to discriminate between subjects at different levels of psychological functioning, as assessed with Kernberg’s concept of personality organization. This study provided some support to the PSYCAP as a personality measure based on an integrative theoretical model. Some of the problems with using CFA on personality data were highlighted.
