Proneness to psychotic-like experiences as a basic personality trait complementing the HEXACO model - A preregistered cross-national study
The goal of the study is to investigate the relationship between the HEXACO personality model and Disintegration – representing a broad spectrum of psychotic-like experiences and behavioral tendencies that are reconceptualized as a personality trait. In this pre-registered study, we predicted that the Disintegration factor would separate from HEXACO.The replicability of the factorial structures of HEXACO and Disintegration subcomponents are investigated across the three national samples (X, Y, and Z), matched on key socio-demographic variables. Exploratory Structure Equation Modeling (ESEM) is used to study the invariance of the hypothesized seven-factor structure. Support for the metric invariance of the seven-factor structure based on HEXACO and Disintegration subcomponents/facets across the three nations was found. The disintegration factor lied clearly outside the HEXACO personality space with each of its nine subcomponents. The disintegration factor appeared to be the most robust among the seven across the samples and units of measurement (facets and items). A broad spectrum of psychotic-like experiences/behavioral tendencies relevant in understanding and explaining many aspects of everyday and long-term (mal)adaptations – as expected - is not captured by the HEXACO model.
