Intensive Evening Outpatient Treatment for Patients With Personality Dysfunction: Early Group Process, Change in...

Entrenched interpersonal difficulties are a defining feature of those with personality dysfunction. Evening treatment-a comprehensive and intensive group-oriented outpatient therapy program-offers a unique approach to delivering mental health services to patients with chronic personality dysfunction. This study assessed change in interpersonal problems as a key outcome, the relevance of such change to future social functioning, and the influence of early group processes on this change.

Consecutively admitted patients (N = 75) to a group-oriented evening treatment program were recruited; the majority were diagnosed with personality disorder. Therapy outcome was represented by scores on the Inventory of Interpersonal Problems. Follow-up outcome was represented by the global score of the Social Adjustment Scale. Group climate, group cohesion, and the therapeutic alliance were examined as process variables.

Patients experienced substantial reduction in distress associated with interpersonal problems; early process factors that reflected a cohesive and engaged group climate and stronger therapeutic alliance were predictive of this outcome. Improvement in interpersonal distress was predictive of global social functioning six months later. The therapeutic alliance most strongly accounted for change in interpersonal problems at posttreatment and social functioning at follow-up.

A comprehensive and integrated outpatient group therapy program, offered in the evening to accommodate patients' real-life demands, can facilitate considerable improvement in interpersonal problems, which in turn influences later social functioning. The intensity and intimacy of peer interactions in the therapy groups, and a strong alliance with the program therapists, are likely interacting factors that are particularly important to facilitate such change.
