Method: Data were collected within two clinical trials ( N = 264). Factorial validity, reliability, and divergent validity from symptoms of ADHD and oppositional defiant disorder (ODD) were assessed. Results: Confirmatory factor analyses revealed that a bifactor model consistent with the theoretical assumption of a general construct of impairment (total scale) and additional specific factors (subscales) provided satisfactory data fit. Model-based reliability estimates showed that both the general construct and specific factors accounted for item variance. Internal consistencies were &gt;.70, part\u2013whole corrected item\u2013scale correlations mostly &gt;.30. Correlations between the WFIRS-P Scales and ADHD and ODD symptoms were low to moderate. Conclusion: The results support the factorial validity, reliability, and divergent validity of the WFIRS-P.<\/jats:p>","DOI":"10.1177\/1087054716661234","type":"journal-article","created":{"date-parts":[[2016,7,28]],"date-time":"2016-07-28T21:59:11Z","timestamp":1469743151000},"page":"1546-1556","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":23,"title":["Functional Impairment in Children With Externalizing Behavior Disorders: Psychometric Properties of the Weiss Functional Impairment Rating Scale\u2013Parent Report in a German Clinical Sample"],"prefix":"10.1177","volume":"23","author":[{"given":"Christina","family":"Dose","sequence":"first","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Psychosomatics and Psychotherapy, Medical Faculty of the University of Cologne, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher","family":"Hautmann","sequence":"additional","affiliation":[{"name":"School for Child and Adolescent Cognitive Behavior Therapy at the University of Cologne"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manfred","family":"Doepfner","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Psychosomatics and Psychotherapy, Medical Faculty of the University of Cologne, Germany"},{"name":"School for Child and Adolescent Cognitive Behavior Therapy at the University of Cologne"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2016,7,28]]},"reference":[{"key":"bibr1-1087054716661234","volume-title":"Diagnostic and statistical manual of mental disorders","author":"American Psychiatric Association","year":"1994","edition":"4"},{"key":"bibr2-1087054716661234","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"bibr3-1087054716661234","doi-asserted-by":"publisher","DOI":"10.1097\/00004583-199902000-00011"},{"key":"bibr4-1087054716661234","doi-asserted-by":"publisher","DOI":"10.1007\/s10488-006-0052-4"},{"key":"bibr5-1087054716661234","doi-asserted-by":"publisher","DOI":"10.1007\/s10488-010-0332-x"},{"key":"bibr6-1087054716661234","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-33306-7"},{"key":"bibr7-1087054716661234","volume-title":"Confirmatory factor analysis for applied research","author":"Brown T.","year":"2006"},{"key":"bibr8-1087054716661234","doi-asserted-by":"publisher","DOI":"10.1177\/0049124192021002005"},{"key":"bibr9-1087054716661234","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-6494.2011.00749.x"},{"key":"bibr10-1087054716661234","unstructured":"Canadian Attention Deficit Hyperactivity Disorder Resource Alliance.
