The COVID-19 pandemic has led to the increased use of digital-based interventions (DBIs) to treat mental illnesses, including trauma-related disorders. However, while evidence for the use of DBIs for PTSD has previously been synthesized, the current review is the first synthesis of research on the use of DBIs for cPTSD. A systematic search of Scopus, PsychINFO, and EBSCOhost was conducted, using search terms targeting \u201ccPTSD\u201d and \u201cDBIs,\u201d to identify research on the use of DBIs to treat cPTSD symptoms. Ten papers were identified, which provided preliminary evidence for the efficacy of DBIs to reduce cPTSD symptoms. Further, DBIs were reported as acceptable by individuals with a history of complex trauma. The paper also provides insight into the therapeutic approaches adopted, digital modalities utilized, safety measures included, and whether\/to what degree support was provided. While DBIs show promise for treating cPTSD, there is substantial room for advancement of the empirical evidence base for these approaches. Both clinical and research-based recommendations are provided separately.<\/jats:p>","DOI":"10.1177\/15248380241238760","type":"journal-article","created":{"date-parts":[[2024,3,27]],"date-time":"2024-03-27T06:20:49Z","timestamp":1711520449000},"page":"3115-3130","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Digital-Based Interventions for Complex Post-Traumatic Stress Disorder: A Systematic Literature Review"],"prefix":"10.1177","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0553-0724","authenticated-orcid":false,"given":"Meg","family":"Blackie","sequence":"first","affiliation":[{"name":"Swinburne University of Technology, Hawthorn, VIC, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4271-4285","authenticated-orcid":false,"given":"Kathleen","family":"De Boer","sequence":"additional","affiliation":[{"name":"Swinburne University of Technology, Hawthorn, VIC, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liz","family":"Seabrook","sequence":"additional","affiliation":[{"name":"Swinburne University of Technology, Hawthorn, VIC, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Glen","family":"Bates","sequence":"additional","affiliation":[{"name":"Swinburne University of Technology, Hawthorn, VIC, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maja","family":"Nedeljkovic","sequence":"additional","affiliation":[{"name":"Swinburne University of Technology, Hawthorn, VIC, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,3,27]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-clinpsy-021815-093006"},{"key":"e_1_3_3_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/da.22723"},{"key":"e_1_3_3_4_1","volume-title":"Digital-based interventions for complex post-traumatic stress disorder: Protocol for a systematic literature review","author":"Blackie M.","year":"2020","unstructured":"Blackie M., De Boer K., Seabrook L., Bates G.
