Completeness in responding to the items of Post\u2010Traumatic Symptom Scale\u201010 and Adverse Childhood Experience Index indicates the suitability of these instruments for both groups of participants. Although the group difference in the randomised controlled trial failed to achieve statistical significance mainly due to the small sample size, the results of the embedded observational study are promising for the conduct of further studies with the modified NET.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jir.13076","type":"journal-article","created":{"date-parts":[[2023,8,19]],"date-time":"2023-08-19T00:46:12Z","timestamp":1692405972000},"page":"1096-1112","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Trauma treatment using Narrative Exposure Therapy adapted to persons with intellectual disabilities or severe chronic mental disorders \u2013 a randomised controlled pilot study with an embedded observational study"],"prefix":"10.1111","volume":"67","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8574-214X","authenticated-orcid":false,"given":"B.","family":"Mayer","sequence":"first","affiliation":[{"name":"Residence Tilia Rheinau  Rheinau Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"U.","family":"Elbing","sequence":"additional","affiliation":[{"name":"Department of Psychology and Psychotherapy Witten\/Herdecke University  Witten Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Ostermann","sequence":"additional","affiliation":[{"name":"Department of Psychology and Psychotherapy Witten\/Herdecke University  Witten Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,8,15]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1108\/AMHID-01-2013-0002"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291717000496"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1080\/19315864.2011.651682"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/1744629517698844"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/1524838020960219"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/bimj.202000196"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2015.01600"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1939-0025.1983.tb03348.x"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1080\/14999013.2016.1228087"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1377\/hlthaff.2022.00520"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-030-97802-0_12"},{"key":"e_1_2_9_13_1","first-page":"595","volume-title":"Handbuch sexualisierte Gewalt.
