Objective:
DSM-IV is the most widely used diagnostic classification system in research, whereas ICD-10 is more widely used clinically. Knowledge of differences is essential when research findings are implemented in daily clinical practice. We examined differences between the two diagnostic systems regarding three major child psychiatric diagnostic categories.
Methods:
A total of 199 consecutively referred, child psychiatric patients were interviewed with a semistructured diagnostic interview (K-SADS-PL) including questions covering specific ICD-10-DCR criteria, and diagnosed according to both diagnostic systems.
Results:
Differences were found regarding the diagnoses major depressive disorder/depressive episode and attention deficit hyperactivity disorder/disturbance of activity and attention. In both cases, more children met DSM-IV-TR criteria than ICD-10-DCR criteria. The diagnosis, oppositional defiant disorder, proved interchangeable between the two diagnostic systems.
Conclusion:
Differences between diagnostic systems must be taken into account when research findings using one diagnostic system are implemented with children diagnosed by another diagnostic system.
