title: Rater agreement on interpersonal psychotherapy problem areas.
abstract: There has been much outcome research on interpersonal psychotherapy (IPT) but little investigation of its components. This study assessed interrater reliability of IPT therapists in identifying interpersonal problem areas and treatment foci from audiotapes of initial treatment sessions. Three IPT research psychotherapists assessed up to 18 audiotapes of dysthymic patients, using the Interpersonal Problem Area Rating Scale. Cohen's kappa was used to examine concordance between raters. Kappas for presence or absence of each of the four IPT problem areas were 0.87 (grief), 0.58 (role dispute), 1.0 (role transition), and 0.48 (interpersonal deficits). Kappa for agreement on a clinical focus was 0.82. IPT therapists agreed closely in rating problem areas and potential treatment foci, providing empirical support for potential therapist consistency in this treatment approach.
