Alternative Models of the Outcome Questionnaire-45

The Outcome Questionnaire-45 (OQ) reliably quantifies level of psychological functioning and change during treatment. The three subscales, however, are not well validated. Could alternative scales, based on personality dimensions or other groupings of psychological problems better explain patterns of response? In Study 1, the intended structure and four alternative models were compared using EFA and CFA in random thirds of a community clinic intake sample (N = 1,822). Oblique and bi-level models were compared. Preferred models were tested for stability in samples from later time points. In Study 2, the models were compared in a nonclinical sample (N = 589). Most bi-level models provided adequate fit per standards previously established for the Outcome Questionnaire-45. A seven-factor model of psychological problems provided better fit than any yet reported for this inventory.

Effectiveness of psychological treatments delivered at a counseling service for students

This study adds to the international literature on the assessment of the effectiveness of psychotherapies delivered by university counseling centers. The present study evaluated the effectiveness of psychotherapy in 226 students (179 women, 47 men; M age = 24.8 yr., SD = 4.0) who started psychotherapy treatment at the counseling service of the University of Bologna, Italy, between January 2008 and October 2010. The Symptom Questionnaire (SQ) was completed twice, before and after the psychotherapeutic treatment. Significant improvements were observed after therapy in all the SQ dimensions' scores, indicating the effectiveness of the therapy in reducing the students' distress.
