The
aim of this study within the ASPIS (Athens Study of Psychosis Proneness
and Incidence of Schizophrenia) was the examination of the latent
structure of schizotypy dimensions amongst a large population of young
male obligatory conscripts in the Greek Airforce during their first week
of military training. Confirmatory Factor Analysis (CFA) was conducted on
1355 reliable responders to the self-rated Schizotypal Personality
Questionnaire (SPQ) that covers all nine aspects of DSM III R Schizotypal
Personality Disorder (SPD).
A
four-factor model (cognitive/perceptual, paranoid, negative and
disorganization
schizotypal dimensions) provided a better fit to the data whilst other
competing models (unitary, two, three, four and five-factor models) failed
to produce better indices of fit. This result is in agreement with recent
findings supporting the notion of a multidimensional construct of the
schizotypy and related schizophrenia phenotype.
