A paper by Boyle et al. entitled, “Classifying child and adolescent psychiatric disorder by problem checklists and standardized interviews” was recently published in the International Journal of Methods in Psychiatric Research. The paper discussed the need for research on the adequacy of self-completed problem checklists to classify child mental disorder based on proxy assessments by parents and self-assessments by adolescents. In addition, the paper argues that that if self-completed problem checklists can classify child mental disorder with similar reliability and validity as standardized diagnostic interviews, this finding would have substantial implications for lowering the burden and cost of assessments in epidemiological studies and clinical research.
