Abstract: A study by Schoenbaum (2017) found that individuals undergoing first-episode psychosis are 24 times more likely to die within a year of diagnosis than the general population. Recent research has found that dimensional models of psychopathology, as opposed to categorical models, yield better results in terms of research utility, treatment outcomes, degree of pathology, and disease etiology (Kotov et al., 2017). Seretti and Ogliati (2004) explored six competing dimensional models of psychosis and found the best fitting model to have five factors: Activation, Positive Symptoms, Disorganization, Depression, and Negative Symptoms. This model of psychosis closely resembles constructs as measured by the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008/2011), a structured personality test, and directly mirrors the constructs as measured by the Positive and Negative Syndrome Scale (PANSS; Kay, Opler, & Fiszbein, 1987), a structured clinical interview. This study used the MMPI-2-RF to elucidate the nature of psychosis, with a focus on a known population, individuals with psychotic disorders, in order to further understand the construct of psychosis.
