A study comparing the two major classification systems found which pattern of use?

1. Two systems are widely recognised: the DSM from the American Psychiatric Association and the ICD from the World Health Organization. 2. Worldwide, the ICD is the one more frequently reached for when a clinical diagnosis is being made. 3. The DSM is the one more valued for research, and most findings on etiology and treatment rest on its criteria. 4. Reversing the pair is the obvious trap, since the DSM is dominant among United States professionals. 5. Neither system dominates both roles, so the two options that award everything to one manual cannot hold. _Source: OpenStax Psychology (1st ed., CC BY 4.0), Ch 15 "Psychological Disorders", section 15.2 Diagnosing and Classifying Psychological Disorders_
