Solving interpersonal problems correlates with symptom improvement in interpersonal psychotherapy: preliminary findings.

Interpersonal psychotherapy (IPT) research has addressed outcome more than mechanism. This study used the novel Interpersonal Psychotherapy Outcome Scale (IPOS) to test the theoretical axiom that symptomatic improvement in IPT reflects resolution of interpersonal problem areas. The IPOS rates change in focal interpersonal problem areas on a 5-point scale.
