Patterns of Change in Interpersonal Problems During and After Short-term and Long-term Psychodynamic Group Therapy: A...

Area of Science:

• Psychology
• Psychotherapy Research

Background:

• Interpersonal problems are a common focus in psychodynamic group therapy.
• Understanding the differential impact of therapy duration is crucial for optimizing treatment.

Purpose of the Study:

• To compare the trajectory of change in interpersonal problems between short-term and long-term psychodynamic group therapy.
• To investigate early and later therapeutic effects based on treatment duration.

Main Methods:

• 167 outpatients with mixed diagnoses were randomized to 20 or 80 weekly sessions.
• Interpersonal problems were assessed using the Inventory of Interpersonal Problems over 3 years.
• Linear mixed models were employed to analyze changes across six time points.

Main Results:

• Short-term therapy demonstrated significantly greater early improvement on the 'cold' interpersonal problem subscale compared to long-term therapy.
• A similar trend was observed for the 'socially avoidant' subscale.
• No significant differences were found between short-term and long-term therapy for other interpersonal problem areas over the 3-year period.

Conclusions:

• While short-term psychodynamic group therapy may offer faster initial symptom reduction in specific areas, long-term therapy does not show superior overall improvement in interpersonal problems over three years.
• Treatment duration may influence the pace but not necessarily the extent of improvement in interpersonal functioning.
