Few issues are of such grave importance to society and to the science and practice of psychology as child maltreatment. Our goal in editing this issue of JSI was to inform scientists across various sub-fields of psychology about the most current knowledge in the field of child maltreatment, broadly defined. The authors of the articles have gone further, pushing past the edge of current knowledge and setting aggressive agendas for future empirical and policy-relevant work. We believe that the result will be enriched future research, practice, policy, and law, and in turn, the increased well-being of children and their families.
