Abstract

The authors describe the validation procedure of the PSI–I Questionnaire on the Ego-states, based on E. Berne’s transactional model (Carta e Cacciarru, 2004). The items of the PSI–I that were found in the previous study have been re-elaborated, submitted to a sample of 1128 italian subjects, and subsequently analyzed using factor analysis with the method of principal components, by extracting 5 components for each of the 5 hypothesized scales. The validity, internal consistency of the scales, and correlations coefficients have been also verified, together with an analysis of the influence of social desiderability on the answers to the questionnaire. The psychometric qualities of the PSI–I demonstrate its ability to discriminate the energetic charge of each of the 5 ego-states in the individual, i.e. the ways by which the subjects represent themselves in relation to their approximation to each ego-state in everyday life.
