简要总结
A primary goal of this study is to investigate the significance of treatment duration, by comparing change after group psychotherapy of varying lengths. A secondary goal is to investigate the predictive value of selected patient variables on outcome: personality pathology, quality of object relations, presence of personality disorder, degree of initial disturbance, and education. One hundred and twenty patients from 5-6 different study sites (consisting of one coordinator and 3 therapists) will be included. Exclusion criteria are psychosis, substance abuse, and organically based symptoms. Patients are interviewed before treatment and one year after termination, and self-rated outcome measures are filled in at 3-month intervals during treatment and at termination. After an initial evaluation, patients are randomized to one of two manualized psychodynamic group psychotherapies with different treatment lengths (20 and 80 sessions). Each therapist will conduct both a short- and a long-term group, and sessions are taped in order to check treatment integrity.
详细描述
The primary goal is to study the effect of treatment duration, by comparing potential change during and after psychodynamic group psychotherapy of varying length (20 and 80 sessions), on measures of symptomatic distress, interpersonal problems, psychosocial functioning, and dynamic personality structure. Hypotheses related to the primary goal: Patients in short- and long-term therapy will symptomatically (SCL-90-R; Derogatis, 1977) be improved to an equal degree, while patients in long-term group psychotherapy will have a larger improvement in interpersonal problems (IIP-64; Alden et al, 1990), psychosocial functioning, and dynamic personality structure.
A secondary goal is to investigate the predictive value of selected patient variables (moderators):
• Personality pathology: Internal object relationships (QOR; Høglend et al, 2003): Patients with better object relationships will improve more both in short- and long-term therapy, and patients with poorer object relationships will improve more in long-term therapy and less in short-term therapy.
Personality disorder: Patients without personality disorders improve equally well in short- and long-term group psychotherapy, while patients with personality disorders will have a substantial reduction in criteria for personality disorder after long-term group psychotherapy.
• Severity of initial disturbance: Patients who have a high severity of the initial disturbance will do better in long-term than in short-term therapy. Patients with low severity of initial disturbance will do equally well in short- and long-term group psychotherapy.
