The Outcome Questionnaire (OQ‐45) in a Dutch population: A cross‐cultural validation

Abstract

The cross-cultural validity of the Outcome Questionnaire (OQ) in the Dutch population has been examined by comparing the psychometric properties and equivalence in factor structure and normative scores of the Dutch OQ with the original American version. Data were collected from a university (n = 268), in a community (n = 810) and from three mental health care organizations (n = 1920). Results show that the psychometric properties of the Dutch OQ were adequate and similar to the original instrument. Some differences in equivalence were found though. In factor analysis, two additional factors were found: one consisting of social role items and another that reflected anxiety and somatic symptoms. Furthermore, normative scores were different for the Dutch and American samples, and this resulted in different cut-off scores for estimating a clinically significant change in the Dutch population.

Psychometric properties of the Swedish version of the Outcome Questionnaire-45 as administered by automated technique in a large sample of mental ill-health patients in Primary Health Care

“…However the results for the different subscales were weaker which is in accordance with results of other studies 17,18,34,35 . Further the total score of the OQ-45 was found to predict level of depression and health-related quality of life in patients, beyond demographic characteristics and other instruments.…”

“…Further the total score of the OQ-45 was found to predict level of depression and health-related quality of life in patients, beyond demographic characteristics and other instruments. Similar to other studies in Europe and USA the results indicate that the total score of the OQ-45 can be of valuable use for clinicians and researcher in the field 17,37,38 . The regression analyses showed that the OQ-45 contributed uniquely to describe the patients' problems.…”

“…Wennberg and co-workers concluded that the psychometric properties of the Swedish version of the OQ-45 in a substances use disorders sample were acceptable except for a low internal consistency of the Social function subscale. This was in accordance with other cross-cultural studies 17,18 .…”

“…À ce jour, aucun tableau normatif spécifique aux populations franco-québécoises, franco-canadiennes ni canadiennes, n'est disponible pour la MI. Par contre, des études de validation de la OQ-45 (version américaine originale de la MI) auprès de populations européennes ont révélé que les propriétés psychométriques de l'instrument traduit sont similaires à la version américaine originale, mais que les normes et les seuils critiques pour évaluer les changements cliniques diffèrent (Chiappelli, Lo Coco, Gullo, Bensi, & Prestano, 2008;Jong et al, 2007).
