Abstract
-
Despite a high prevalence of comorbid personality disorder traits in those considered to be high risk (or prodromal) for schizophrenia (Woods et al., 2009), and the known negative effects of personality disorders on treatment in schizophrenia (e.g., Tyrer et al., 2000), little is known regarding the effect of personality disorder traits on the treatment of prodromal individuals. Using a ten-year sample from the Recognition and Prevention (RAP) Program at Zucker Hillside Hospital in New York, this dissertation used retrospective, naturalistic methods to investigate personality disorder traits and the ways in which these traits affected both the assessment and the treatment of prodromal symptoms. Results did not support that personality disorder traits moderated treatment outcomes, but did support that particular treatment techniques were used more often with certain personality traits (e.g., borderline personality disorder) or symptom severities. In addition, it was found that, overall, particular treatment techniques were associated with reductions in negative symptoms, but not with positive symptom or global functioning changes. Results also indicated that aspects of the suspiciousness and hallucinations scales from the Structured Interview for Prodromal Syndromes (SIPS) were associated with personality traits and not predictive of transition to psychosis. These results suggest that treatment planning could use symptom presentation on intake to determine the most effective treatment techniques. Further research is required to further the diagnostic and predictive ability of assessment measures, including the important determination of whether currently considered prodromal symptoms may be better accounted for by personality traits.
