What is the difference in dsm iii and dsm ii?

The main difference between DSM-II and DSM-III is that DSM-III introduced a systematic multiaxial diagnostic system and a more comprehensive approach to diagnosis. DSM-III also included specific diagnostic criteria for each disorder, moving away from the broader diagnostic categories of DSM-II. Additionally, DSM-III incorporated a more atheoretical approach to diagnosis, focusing on observable symptoms rather than theoretical explanations.
