PROGNOSTIC UTILITY OF SUBCOMPONENTS OF THE BORDERLINE PERSONALITY CONSTRUCT IN BULIMIA-NERVOSA

We examined various components of the 'borderline personality construc t' as predictors of initial response to treatment in 61 bulimic patien ts. At pre-treatment, a 'borderline/non-borderline' distinction was es tablished using DSM III-R criteria, and other components of 'borderlin e' pathology ('borderline traits', object-relations disturbances, mala daptive defences and mood pathology) were assessed using self-report. Self-reported eating and psychiatric symptoms were obtained at initial and three-month evaluations. Using hierarchical regression analyses, we controlled effects of initial eating and psychiatric symptoms, and then evaluated various measures of the borderline construct as predict ors of later symptom severity. Categorical borderline PD diagnoses wer e linked to poorer response on eating attitudes and symptoms, and fine -grained analyses indicated that this prognostic effect might be media ted by mood and object-relations disturbances. Findings therefore seem ed to isolate specific subcomponents of borderline personality patholo gy that predicted poorer response on eating symptoms.
