The Contribution of Mixed Methods Research to the Field of Childhood Trauma: A Narrative Review focused on Data Integration

In mixed methods research (MMR), integrating the quantitative and the qualitative components of a study is assumed to result in additional knowledge (or "yield"). This narrative review examines the extent to which MMR is used in the field of childhood trauma and provides directions for improving mixed methods studies in this field. A systematic literature search resulted in 13 studies that were achieving four different research objectives: (a) measures and meaning, (b) intervention evaluation, (c) theory building, and (d) measurement instrument development and validation. Although some studies produced yield by integrating the components, there is room for improvement and better use of MMR's potential. We conclude by presenting recommendations for improving the application and dissemination of MMR in childhood trauma. © The Author(s) 2013.
