Very little research has examined the role of personality in important life outcomes and support needs of adults with intellectual disabilities. This exploratory study includes a sample of 102 community-dwelling adults with intellectual and developmental disabilities, and begins to evaluate the relative contributions of general personality and personality disorder as it they concern their adaptive functioning, Axis I psychopathology symptoms, and residential and vocational supports.
Observer ratings of personality disorder and Five Factor Model and Reiss Profile general personality functioning were obtained from direct service providers who knew the participants well, and archival file data (e.g., IQ, adaptive functioning scores, medications prescribed, and diagnoses) were collected after informed consent and assent were obtained from the participants. The results suggest that both personality and personality disorder, relate the intensity of supports required, the number of psychiatric medications prescribed, maladaptive behavior, and the amount of Axis I psychopathology exhibited by the participants. Results of the study are discussed with reference to implications for service delivery and planning and future research.
