Methodological considerations in the evaluation of the convergence of psychiatric diagnoses and parent-informant checklists.

Psychiatric diagnoses and objective parent checklists are alternative ways to describe child adjustment problems. There has recently been interest in evaluating the degree of agreement or convergence between these sources of information. This paper addresses three issues neglected by researchers in this area. The appropriateness of the use of indices of sensitivity and specificity to describe the correspondence of diagnoses and checklist scores is questioned. Implications of failure to consider the reliability of diagnoses in interpreting diagnosis-checklist agreement are discussed. Also, possible parameters of diagnosis-checklist agreement that should be identified by researchers are reviewed. Suggestions for improving research in this area are offered.
