CONTEXT

Borderline personality disorder is a severe and chronic psychiatric condition, prevalent throughout health care settings. Only limited effects of current treatments have been documented.

OBJECTIVE

To compare the effectiveness of schema-focused therapy (SFT) and psychodynamically based transference-focused psychotherapy (TFP) in patients with borderline personality disorder.

DESIGN

A multicenter, randomized, 2-group design.

SETTING

Four general community mental health centers.

PARTICIPANTS

Eighty-eight patients with a Borderline Personality Disorder Severity Index, fourth version, score greater than a predetermined cutoff score.

INTERVENTION

Three years of either SFT or TFP with sessions twice a week.

MAIN OUTCOME MEASURES

Borderline Personality Disorder Severity Index, fourth version, score; quality of life; general psychopathologic dysfunction; and measures of SFT/TFP personality concepts. Patient assessments were made before randomization and then every 3 months for 3 years.

RESULTS

Data on 44 SFT patients and 42 TFP patients were available. The sociodemographic and clinical characteristics of the groups were similar at baseline. Survival analyses revealed a higher dropout risk for TFP patients than for SFT patients (P = .01). Using an intention-to-treat approach, statistically and clinically significant improvements were found for both treatments on all measures after 1-, 2-, and 3-year treatment periods. After 3 years of treatment, survival analyses demonstrated that significantly more SFT patients recovered (relative risk = 2.18; P = .04) or showed reliable clinical improvement (relative risk = 2.33; P = .009) on the Borderline Personality Disorder Severity Index, fourth version. Robust analysis of covariance (ANCOVA) showed that they also improved more in general psychopathologic dysfunction and measures of SFT/TFP personality concepts (P<.001). Finally, SFT patients showed greater increases in quality of life than TFP patients (robust ANCOVAs, P=.03 and P<.001).

CONCLUSIONS

Three years of SFT or TFP proved to be effective in reducing borderline personality disorder-specific and general psychopathologic dysfunction and measures of SFT/TFP concepts and in improving quality of life; SFT is more effective than TFP for all measures.
