The ACE\u2013International Questionnaire (ACE-IQ) was developed to assess categories of ACEs (e.g., sexual, emotional, and physical abuse) in internationally representative samples. Though the ACE-IQ has been used world-wide, little work has examined the structure of this measure. Further, much of the modeling techniques implemented lacked theoretical rationale. The present work used two principal components analyses (PCA) to evaluate the ACE-IQ structure using both the identified ACE categories as defined by the World Health Organization (WHO) and using the ACE-IQ items as individual indicators. Using the WHO method, a two-component structure was indicated. Alternatively, a PCA of the individual items yielded a six-component structure. Results highlight the importance of theoretically grounded measure evaluation and the potential distinctions amongst types of ACEs. Implications and future directions for research and practice are discussed.<\/jats:p>","DOI":"10.1177\/10775595211043122","type":"journal-article","created":{"date-parts":[[2021,9,25]],"date-time":"2021-09-25T10:25:35Z","timestamp":1632565535000},"page":"527-538","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":21,"title":["Modeling the Adverse Childhood Experiences Questionnaire\u2013International Version"],"prefix":"10.1177","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3374-2313","authenticated-orcid":false,"given":"Jordan A.","family":"Gette","sequence":"first","affiliation":[{"name":"Department of Psychological Science, Texas Tech University, Lubbock, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7462-8798","authenticated-orcid":false,"given":"Tre D.","family":"Gissandaner","sequence":"additional","affiliation":[{"name":"Department of Psychological Science, Texas Tech University, Lubbock, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew K.","family":"Littlefield","sequence":"additional","affiliation":[{"name":"Department of Psychological Science, Texas Tech University, Lubbock, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chelsy S.","family":"Simmons","sequence":"additional","affiliation":[{"name":"Department of Psychological Science, Texas Tech University, Lubbock, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam T.","family":"Schmidt","sequence":"additional","affiliation":[{"name":"Department of Psychological Science, Texas Tech University, Lubbock, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2021,9,25]]},"reference":[{"issue":"3","key":"bibr1-10775595211043122","first-page":"320","volume":"69","author":"Ashraf F.","year":"2019","journal-title":"JPMA.
