The sample comprised 2040 individuals. The internal structure of the nine factors of the SCL\u201092 questionnaire was evaluated by Mokken\u2010Loevinger analysis and Rasch analysis.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:\u2002<\/jats:bold>\n                    In total, 1153 persons or 58% returned the questionnaire fully completed. Mokken analysis found all scales apart from the psychoticism scale acceptable. The Rasch analysis found most of the subscales to be robust. Minor problems were seen for the scales of phobic anxiety, obsession\u2010compulsion and depression. Analysis of the Global Severity Index showed that the Rasch model was rejected for the full 92\u2010item scale, but not for a scale consisting of the 63 items from the non\u2010psychotic subscales. Spearman correlations among the subscales were all positive (range 0.34\u20130.79) and so were correlations between each of the subscales and the Global Severity Index (range 0.55\u20130.91).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusion:\u2002<\/jats:bold>\n                    In this sample from the Danish general population the non\u2010psychotic subscales, i.e. the subscales covering psychological distress were observed to function well. In a general population sample, the 63 non\u2010psychotic items primarily appear to reflect one broad dimension of distress.\n                  <\/jats:p>","DOI":"10.1111\/j.1600-0447.2004.00399.x","type":"journal-article","created":{"date-parts":[[2004,7,29]],"date-time":"2004-07-29T16:52:11Z","timestamp":1091119931000},"page":"225-229","source":"Crossref","is-referenced-by-count":226,"title":["The SCL\u201090 and SCL\u201090R versions validated by item response models in a Danish community sample"],"prefix":"10.1111","volume":"110","author":[{"given":"L.
