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 (Perceptual Distortions, General Executive/Cognitive Impairment, Enhanced Awareness, Paranoia, Mania, Flattened Affect, Apathy/Depression, Somatoform Dysregulation, and Magical Thinking) that are reconceptualized as a personality trait. In this preregistered study, we predicted that the Disintegration factor would separate from HEXACO. The replicability of the factorial structures of HEXACO and Disintegration subcomponents is investigated across the three national samples (UK, Germany, and Serbia), matched on key socio-demographic variables. Exploratory Structural Equation Modeling (ESEM) is used to study the invariance of the hypothesized seven-factor structure (six HEXACO plus Disintegration). 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 outside the HEXACO personality space with each of its nine subcomponents. The Disintegration factor appeared to be among the most coherent and replicable of 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 is not captured by the HEXACO model.
