psychiatric rate standardization
Statistical adjustment technique to control for demographic differences when comparing psychiatric disorder rates across populations.
Full Definition
A statistical method used in psychiatric epidemiology to adjust disorder rates for differences in population characteristics, most commonly age and sex, enabling valid comparisons across different geographic areas or time periods. Direct standardization applies the age-specific rates from study populations to a standard population structure, while indirect standardization applies standard rates to study population structures. This technique is essential for psychiatric epidemiology because mental health disorders have strong age and sex patterns that can confound population comparisons.
Usage
Usage note: Distinguish carefully from standardized prevalence ratio or standardized morbidity ratio in editorial contexts.
