The Outcome Questionnaire 45.2. Italian validation of an instrument for the assessment of phychological treatments
Abstract
Summary: Aims– The Outcome Questionnaire (OQ-45.2; Lambert et al., 2004) was designed to measure important areas of functioning (symptoms, interpersonal problems and social role functioning) that are of central interest in mental health. The crosscultural validity of the OQ-45.2 in the Italian population has been examined by comparing the psychometric properties and equivalence in factor structure and normative scores of the Italian OQ with the original American version.Method– Data were collected at university (N=461), in community (N=61) and in three mental health care organisations (N=301).Results– Results showed that the psychometric properties of the Italian OQ were adequate and similar to the original instrument. The CFA supported the multidimentional construct system of the instrument. Furthermore, normative scores were different for the Italian and American samples and this resulted in different cutoff scores for estimating clinically significant change in the Italian population.Conclusions– The Italian version of the OQ-45.2 appears promising as a measure of general psychological distress, and it could be used to measure the psychotherapy outcome in routine clinical practice.

“The Italian version [30] is used to assess the effectiveness of clinical interventions. It is a self-report questionnaire composed of 45 items. Subscales are symptoms of distress, interpersonal relations, and social role functioning. The total α score obtained in the validated version on a clinical sample is excellent (α = .90).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
