Examining the Performance of the MMPI-2-RF in a Sample of Pretransplant Military Veterans.

ABSTRACT

The present study aimed to describe the personality and psychopathology dimensions reported by veterans seeking organ transplantation, as well as to identify those dimensions associated with subsequent presurgical recommendations and transplant outcomes. Data were collected from 245 veterans undergoing a pretransplant psychological evaluation that included the MMPI-2-RF. Three treatment recommendations resulting from these evaluations, three recommendation adherence variables, and two transplant outcomes were extracted from electronic medical records. The sample's MMPI-2-RF scale scores were compared to the normative sample and two other presurgical samples and contrasted across subgroups defined by organ transplanted. Point-biserial correlations and logistic regression analyses examined associations between MMPI-2-RF scale scores and the eight measured outcomes. Results indicated that over-reporting, internalizing tendencies, negative emotionality, and a lack of positive emotions were uniquely predictive of mental health treatment recommendation, whereas somatic over-reporting, externalizing tendencies, and disinhibition were predictive of substance use treatment recommendation. Veterans who reported higher levels of activation were less likely to initiate mental health treatment. Finally, veterans with greater somatic preoccupation were less likely to be listed for organ transplant. More suspicious and mistrustful veterans were less likely to receive the transplant. These findings offer support for the role of the MMPI-2-RF in veteran pretransplant evaluations.
