psychiatric dose-response
The relationship between exposure intensity or duration and psychiatric disorder risk or severity.
Full Definition
A fundamental concept in psychiatric epidemiology describing the quantitative relationship between the level of exposure to risk factors and the probability or severity of psychiatric outcomes. This relationship can be linear, threshold-based, or follow other mathematical patterns. Examples include the relationship between alcohol consumption levels and depression risk, trauma exposure intensity and PTSD severity, or cumulative stress exposure and anxiety disorders. Establishing dose-response relationships strengthens causal inference and informs prevention strategies by identifying optimal intervention thresholds.
