Confirmatory factor analyses best supported a three\u2010factor model for the PTQ\u2010C; however, hypotheses of both perfect and close fit were rejected, and a subsequent bifactor model suggested minimal unique variance for each subscale. Results demonstrated good internal consistency, convergent validity and divergent validity for the total score and three PTQ\u2010S subscales: core characteristics, perceived unproductiveness, and consumed mental capacity of negative repetitive thinking. PTQ\u2010C scores did not account for additional variance in anxiety symptoms once worry was considered, indicating that retention of a content\u2010specific measure may be warranted in clinical samples. Findings emphasize the importance of validating clinically relevant measures which were developed with subclinical populations in samples with diagnosed mental health disorders.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Practitioner points<\/jats:title>\n                    <jats:p>\n                      <jats:list list-type=\"bullet\">\n                        <jats:list-item>\n                          <jats:p>Validates Perseverative Thinking Questionnaire in anxious and depressed youth.<\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>Support for convergent and divergent validity, and internal consistency.<\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>Results suggest measure is appropriate for complex and comorbid presentations.<\/jats:p>\n                        <\/jats:list-item>\n                      <\/jats:list>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/bjc.12336","type":"journal-article","created":{"date-parts":[[2021,10,8]],"date-time":"2021-10-08T14:01:50Z","timestamp":1633701710000},"page":"242-254","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Validation of the Child version of the Perseverative Thinking Questionnaire of repetitive negative thinking in young people with diagnosed depressive and anxiety disorders"],"prefix":"10.1111","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2435-0713","authenticated-orcid":false,"given":"Caitlin","family":"Hitchcock","sequence":"first","affiliation":[{"name":"MRC Cognition and Brain Sciences Unit University of Cambridge UK"},{"name":"Melbourne School of Psychological Sciences University of Melbourne UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renee L.","family":"Brown","sequence":"additional","affiliation":[{"name":"School of Psychology The University of Queensland Brisbane Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vanessa E.","family":"Cobham","sequence":"additional","affiliation":[{"name":"School of Psychology The University of Queensland Brisbane Queensland Australia"},{"name":"Children\u2019s Health Queensland, Child and Youth Mental Health Service Brisbane Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,10,6]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"237","article-title":"Development of a short questionnaire for use in epidemiological studies of depression in children and adolescents","volume":"5","author":"Angold A.","year":"1995","journal-title":"International Journal of Methods in Psychiatric Research"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10862-017-9624-8"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10862-014-9446-x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004583-199910000-00011"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/0005-7967(83)90121-3"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7610.2006.01646.x"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0005-7967(96)00116-7"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.psychres.2018.07.016"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1093\/med-psych\/9780199340989.001.0001"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbtep.2010.12.003"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7610.2010.02285.x"},{"key":"e_1_2_7_13_1","volume-title":"Principles and practice of structural equation\u00a0modelling","author":"Kline R.","year":"2005"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.janxdis.2010.03.008"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1177\/1073191117693923"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2013.06.014"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1745-6924.2008.00088.x"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1080\/15374410801955896"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1037\/met0000045"},{"key":"e_1_2_7_20_1","volume-title":"Anxiety Disorders Interview Schedule (ADIS\u2010IV): Child and parent interview schedules","author":"Silverman W.
