Time limited psychodynamic group therapy

Abstract

We explore predictors of participation in additional treatment within one year after termination of 39 sessions of psychodynamic group therapy (n=130). The sample was biased due to a 33% dropout at the one-year follow-up of symptomatic less improved treatment completers (N=194). Outcome predictors were the Symptom Check List 90 Revised (SCL-90-R), Millon Clinical Multiaxial Inventory II (MCMI-II), non-symptomatic Psychodynamic Focus, retrospective outcome evaluations, and socio-demographic and psychiatric variables.At follow-up, 57.6% of the patients had been seeking additional treatment for psychological or psychiatric problems; the percentage was 41.6%, when further treatment was defined as participating in more than 5 sessions. The majority (94.8%) was treated within the public health services.Participation in additional treatment was predicted by improvement on the MCMI Antisocial personality disorder scale and a higher SCL-90-R Somatization end-state score. When additional treatment was defined as receiving more than 5 sessions, lack of paid work before treatment (odds ratio 8.0), lack of social network support (odds ratio 2.9), and the Antisocial pre- post difference score (odds ratio 1.6) were significant predictors explaining a total of 26.4% variance. Neither SCL-90-R Global Severity Index (GSI) reliable and clinically significant improvement, therapist recommendations of further therapy, nor socio-demographic, psychiatric and treatment outcome variables were significantly associated with seeking additional treatment.Even though we identified only a small number of predictors for participation in further treatment, our study nevertheless points to the importance of employing reliable and validated methods in the evaluation of treatment outcome and further treatment planning.
