Three-year trials of personal therapy among schizophrenic patients living with or independent of family, I: Description of study and effects on relapse rates.

OBJECTIVE: The study of individual psychotherapeutic approaches to the treatment of schizophrenia has yielded equivocal findings, partly because of methodologic problems. Further, the ability of psychosocial treatments to prevent psychotic relapse appears to lessen over time. The authors' goal was to develop and test a demonstrably effective individual therapy for schizophrenia. METHOD: Using a study design that addressed previous methodologic issues, the authors evaluated personal therapy specifically designed to forestall late relapse in patients with schizophrenia. They evaluated the effectiveness of personal therapy over a period of 3 years after hospital discharge among 151 patients with schizophrenia or schizoaffective disorder diagnosed according to Research Diagnostic Criteria. The patients were randomly assigned to receive either personal therapy or contrasting therapies in one of two concurrent trials. One trial studied patients who were living with family (N = 97); the other studied patients who were living independent of family (N = 54). RESULTS: All of the patients had extensive psychiatric histories, but only 44 (29%) experienced recurrent psychotic episodes over the 3-year study period, and only 27 (18%) prematurely terminated the study; most of those who left the study were in the no-personal-therapy conditions. Among patients living with family, personal therapy was more effective than family and supportive therapies in preventing psychotic and affective relapse as well as noncompliance. However, among patients living independent of family, those who received personal therapy had significantly more psychotic decompensations than did those who received supportive therapy. CONCLUSIONS: Personal therapy had a positive effect on adverse outcomes among patients who lived with family. However, personal therapy increased the rate of psychotic relapse for patients living independent of family. The application of personal therapy might best be delayed until patients have achieved symptom and residential stability.

Three-year trials of personal therapy among schizophrenic patients living with or independent of family, II: Effects on adjustment of patients.

OBJECTIVE: Previous analyses of the personal and social adjustment of outpatients with schizophrenia have either relied on the assessment of unrepresentative patients who survived without relapse or used analyses that included relapse assessments, a potential confound when different rates of relapse existed among treatment conditions. The authors' goal was to conduct a study of the effects of personal therapy on outcome that was designed to take into consideration the effects of relapse. METHOD: They evaluated the effectiveness of personal therapy over 3 years after hospital discharge among 151 patients with schizophrenia or schizoaffective disorder. The patients were randomly assigned to receive personal therapy or contrasting therapies in one of two concurrent trials. One trial included patients who were living with family (N = 97); the other included patients who were living independent of family (N = 54). Patients were assessed at 6-month intervals over 3 years of treatment on measures of personal and social adjustment; patients who relapsed and restabilized and those who did not relapse were included. RESULTS: Personal therapy had positive effects on broad components of social adjustment (role performance) but had few differential effects on symptoms, and patients receiving personal therapy remained more anxious than patients who received family or supportive therapy. For patients who were living with family, personal therapy led to better outcomes in overall performance than did the other treatments. Although family therapy had only one positive effect on patients' social adjustment, the personal adjustment (residual symptoms) of patients who received family therapy appeared to improve more than that of patients receiving personal or supportive therapy. For patients not living with family, personal therapy was more successful than supportive therapy in improving work performance and relationships out of the home. Longitudinal effects of personal therapy on symptoms were similar to those of family and supportive therapies, particularly in the first 2 years, but personal therapy effect sizes increased over time on measures of social adjustment. CONCLUSIONS: Personal therapy has pervasive effects on the social adjustment of patients with schizophrenia that are independent of relapse prevention. Supportive therapy, with or without family intervention, produces adjustment effects that peak at 12 months after discharge and plateau thereafter. However, personal therapy, a definitive psychosocial intervention, continues to improve the social adjustment of patients in the second and third years after discharge. Brief treatment would appear to be less effective than a long-term, disorder-relevant intervention for schizophrenia.

Personal therapy: a disorder-relevant psychotherapy for schizophrenia.

While the long-term care of ambulatory schizophrenia patients requires highly effective interpersonal treatment skills among clinicians, there is little evidence to support an empirically validated individual psychotherapy of schizophrenia. Personal therapy (PT) attempts to address the apparent limitations of traditional psychotherapy by modifying the "model of the person" to accommodate an underlying pathophysiology, minimizing potential iatrogenic effects of maintenance antipsychotic medication, controlling sources of environmental provocation, and extending therapy to a time when crisis management has lessened and stabilization is better ensured. By means of graduated, internal coping strategies, PT attempts to provide a growing awareness of personal vulnerability, including the "internal cues" of affect dysregulation. The goals are to increase foresight through the accurate appraisal of emotional states, their appropriate expression, and assessment of the reciprocal response of others. The strategies are supplemented by phase-specific psychoeducation and behavior therapy techniques. Practical issues in the application of this new intervention are discussed. Preliminary observations from two samples of patients, one living with and the other living independent of family, suggest differential improvement over time among PT recipients.

Family psychoeducation, social skills training, and maintenance chemotherapy in the aftercare treatment of schizophrenia. II. Two-year effects of a controlled study on relapse and adjustment. Environmental-Personal Indicators in the Course of Schizophrenia (EPICS) Research Group.

We demonstrated earlier that a novel family psychoeducational approach and an individual social skills training approach designed for patients living in high-expressed emotion households each reduced schizophrenic relapse by one-half when compared with medication controls in the 1st year after hospital discharge. The combination of treatments resulted in no relapse. Results have now been obtained after 2 years of continuous treatment. By 24 months, a persistent and significant effect of family intervention on forestalling relapse was observed, but the effect of social skills training was lost late in the 2nd year. There was no additive effect on relapse that accrued to the combination of treatments. Beyond 2 years, however, the effect of family intervention was likely compromised as well. Treatment effects on the adjustment of survivors were circumscribed, due, in part, to study design characteristics. Effects generally favored the social skills-alone condition at 1 year and the family condition or combined family/social skills condition at 2 years.

Family psychoeducation, social skills training, and maintenance chemotherapy in the aftercare treatment of schizophrenia. I. One-year effects of a controlled study on relapse and expressed emotion.

Relapse rates averaging 41% in the first year after discharge among schizophrenic patients receiving maintenance neuroleptic treatment led to the development of two disorder-relevant treatments: a patient-centered behavioral treatment and a psychoeducational family treatment. Following hospital admission, 103 patients residing in high expressed emotion (EE) households who met Research Diagnostic Criteria for schizophrenia or schizoaffective disorder were randomly assigned to a two-year aftercare study of family treatment and medication, social skills training and medication, their combination, or a drug-treated condition. First-year relapse rates among those exposed to treatment demonstrate a main effect for family treatment (19%), a main effect for social skills training (20%), and an additive effect for the combined conditions (0%) relative to controls (41%). Effects are explained, in part, by the absence of relapse in any household that changed from high to low EE. Only the combination of treatment sustains a remission in households that remain high in EE. Continuing study, however, suggests a delay of relapse rather than prevention.

Social skills training and endogenous depression.

The clinical response to social skills training was studied in four women with definite endogenous depression (melancholia) to ascertain if a behavioral intervention could be effective with more severe and pervasive affective syndromes. Three of four patients responded to social skills training, although both patients available for longitudinal follow-up relapsed within 24 months post-treatment. Implications for research and practice are discussed.

A behavioral program for the management of anorexia and bulimia.

The results of a behavioral treatment program for two cases of anorexia and bulimia are presented. The program involved inpatient contingency management for weight gain, thought stopping, flooding, response prevention for bulimia and emesis, and training in self-monitoring skills of caloric intake and weight. The results for both cases indicate that the inpatient program was associated with specific increases in body weight and caloric consumption which were generally maintained at 2-year follow-ups. Flooding and response prevention also appeared to be generally successful in reducing both emesis and bulimia urges and episodes, whereas thought stopping did not appreciably change these behaviors. Serum pituitary gonadotropins (follicle-stimulating hormone and luteinizing hormone) were also restored to normal or near normal levels. Self-monitoring of eating behaviors including caloric intake, emesis, and bulimia seemed to be a useful maintenance strategy and provided timely data for the application of booster treatments during later follow-up intervals.
