Introduction to special section: comorbidity and treatment implications.

This article initiates the special section on comorbidity and treatment implications. The presence of comorbidity is recognized, the multiple meanings of comorbidity are mentioned, and an invitation for much-needed research on comorbidity and related treatment is extended.     

Factors Related to Drop-outs by Borderline Patients : Treatment Contract and Therapeutic Alliance

High patient drop-out rates have traditionally interfered with both treatment and study of patients with borderline personality disorder (BPD). The authors tested hypotheses that an adequate treatment contract, a positive therapeutic alliance, and the severity of illness would all correlate with continuation of treatment versus drop-out in a BPD cohort receiving psychodynamic psychotherapy. Therapists' contributions to the contract and to the alliance correlated with the length of treatment. Patients' impulsivity was negatively related to length of treatment. This study supports the view that the therapist's technique plays a role in engaging the borderline patient to remain in treatment.     

Predictors of dropout in psychodynamic psychotherapy of borderline personality disorder

This study aimed to identify patient factors that predict early dropout from psychodynamic psychotherapy for borderline personality disorder (BPD). Thirty-six BPD patients began an open-ended course of twice per week psychodynamic psychotherapy that was defined in a treatment manual and supervised. Dropout rates were 31% and 36% at 3 and 6 months of therapy, respectively. Survival analysis techniques demonstrated that age and hostility ratings predicted early dropout, with continuers more likely to be older and expressing lower levels of hostility than dropouts. Many variables hypothesized to predict dropout failed to do so. Both the positive and negative findings are discussed relative to the literature.     

Conflict begets conflict: Executive control,mental state vacillations,and the therapeutic alliance in treatment of borderline personality disorder

This study evaluated the psychometric properties of the 4 scales of the Behavioral Health Questionnaire-20 (BHQ-20): Global Mental Health, Well-Being, Symptoms, and Life Functioning. Four samples were used: community adults, college students, college students in counseling, and adults in outpatient psychotherapy. Support was found for internal consistency and 2-week test-retest reliability. For construct validity, the BHQ-20 scales distinguished levels of pathology among the samples and were sensitive to improvement across 3 psychotherapy sessions. Concurrent validity correlations with the scales of established measures were at least moderately high. Higher correlations were also found between the BHQ-20 scales and the nonanalogous scales of the established measures. These results, along with high correlations among the BHQ-20 scales, indicated the presence of 1 primary mental health dimension accounting for the variance. The BHQ-20 was proven to be a generally reliable, valid questionnaire that is distinguished by the efficiency with which it assesses mental health.     

Blood volume control by biofeedback and dialysis-induced symptomatology. A short-term clinical study

In earlier studies, a reduction in intradialytic procedures was observed in patients with severe intradialytic hypotension symptomatology by the use of blood volume controlled biofeedback systems. However, few data are present on the use of biofeedback-controlled treatments in patients experiencing minor intradialytic symptoms. In the present study, 157 standard and 158 biofeedback-controlled treatments were compared during a 2-month period in 16 hemodialysis patients. Both the percentage of hypotensive episodes (6.3 +/- 11.3 vs. 15.8 +/- 18.3%; p < 0.05) as well as other intradialytic symptoms (cramps, nausea, headache, abdominal pain) (11.0 +/- 12.8 vs. 18.1 +/- 16.9%; p < 0.05) were significantly less during biofeedback-controlled treatments compared to standard dialysis treatments, despite a similar decline in relative blood volume (8.8 +/- 3.5 vs. 8.3 +/- 3.1%; p = n.s.). Interdialytic weight gain and intradialytic rise in plasma sodium levels were comparable. Concluding, in this short-term preliminary study, blood volume controlled biofeedback improved dialysis tolerance also in patients with minor intradialytic symptomatology.     

Impact of family burden and patient symptom status on clinical outcome in bipolar affective disorder

Studies have suggested that family burden adversely affects clinical outcome in the major mental disorders. Logistic regression analysis was used to evaluate the effect of family burden reported at baseline (acute model), or 7 months (stabilization model), on the risk of having a subsequent affective episode, in a sample of 264 patients with Research Diagnostic Criteria-diagnosed bipolar illness. Higher levels of baseline burden and a depressive index episode significantly increased the risk for a major episode at 7 months. Higher 7-month burden significantly increased the risk for a major episode at 15 months among patients with relatively low 7-month BPRS symptom levels. Caregiver burden reported at times of symptom relapse and during stabilization predicts subsequent adverse clinical outcomes among patients with bipolar disorder and suggests a need for family support.     

Personality disorders: a discussion of current status and future directions for research, practice, and policy

This article is the result of a panel discussion on future directions in personality disorders held at the 1998 Meeting of the Society for Psychotherapy Research in Snowbird Utah. Three experts in the field of personality disorders were invited to participate in a dialogue on priorities and directions for research, practice, and policy in this area. Topics discussed amongst the panelists included the following: 1) relevance of psychotherapy process research for treatments of personality disorders, and potential fruitful directions for such research; 2) what has been learned from outcome research in treatment of personality disorders, and directions for such research that are likely to be most productive in improving treatments; 3) the extent to which research has influenced clinical practice and how existing gaps might be addressed; 4) policy questions related to payment for treatment of personality disorders.     

Toward the development of a clinically useful approach to psychotherapy research

The controversial move toward the development of a consensus on evidence-based or empirically supported therapies may be seen as an international crisis facing psychotherapists. Researchers long have complained that practicing therapists all too often continue to guide what they do therapeutically on the basis of their clinical experience and not the available research findings. Practicing therapists long have complained that therapy research bears only a remote resemblance to what goes on in actual clinical practice and that research reports are written for other researchers, not for clinicians. In the hope of turning our current crisis into an opportunity, this panel involved a dialogue that was designed to bridge this clinical-research gap.     

Comorbidity of borderline personality disorder

In a retrospective study of 180 inpatients with DSM-III borderline personality disorder (BPD), the degree and direction of psychiatric comorbidity were used to examine the extent to which BPD is a homogeneous entity with clearly defined boundaries. Ninety-one percent of patients with BPD had one additional diagnosis, and 42% had two or more additional diagnoses. Both patients with BPD and controls with other personality disorders had similar rates and directions of comorbidity. The two groups did not differ significantly in prevalence of affective disorder. The DSM-III BPD appears to constitute a very heterogeneous category with unclear boundaries, overlapping with many different disorders but without a specific association with any one Axis I disorder. Comorbidity in patients with BPD may reflect base rates of psychopathology rather than anything inherent to BPD. Future studies should control for comorbidity to ensure homogeneity of comparison groups.
