Our findings show \u201cchildhood trauma\u201d being the most frequently examined construct, followed by \u201cchild maltreatment\u201d or \u201cchild abuse.\u201d The short version of the Childhood Trauma Questionnaire was the dominant instrument. Physical abuse, emotional abuse, and sexual abuse were most frequently investigated, and indeed the field appears generally to focus on child abuse and neglect over other adversities. Significant psychometric heterogeneity was observed in the selection and summarization of instrument items, with only 59% of studies documenting original psychometric validation and 22% reporting reliability in their datasets.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>This review highlights substantial methodological heterogeneity in the field, pointing out biases in the research on childhood adversity and psychosis.
