Abstract

The factor structure of psychopathology has been debated in the literature, with studies showing support for several models, including one-, two-, and three-factor solutions. The factor structures often vary as a function of what symptoms and diagnoses are included, and when a wide array of diagnoses are present, a three-factor solution is often found. Personality has been shown to be related to psychopathology and its higher order structures, but there is little research regarding neurobiological associations that take into account the factor structure of psychopathology along with personality. This dissertation examined the factor structure of a wide range of psychopathology, and its associations with both personality and neurobiological correlates using EEG paradigms in a sample of college students. When total scores were examined, a three-factor structure was supported, and a six-factor structure was supported when examining subscales. Feelings of alienation and a tendency to become stressed were related to most psychopathologies. EEG findings suggest that symptom clusters not typically captured in the internalizing-externalizing factor structure are less likely to experience emotional reactions, and possibly a lack of attention and engagement in general.
