ecological validity
The extent to which research findings can be generalized to real-world clinical settings and everyday functioning.
Full Definition
Ecological validity refers to the degree to which the conditions, procedures, and findings of a research study reflect the circumstances and behaviors that occur in real-world clinical practice. In psychiatric research, this concept addresses whether laboratory or clinical trial results accurately predict how treatments will perform in actual clinical settings with diverse patient populations, varying adherence patterns, and complex comorbidities. Studies with high ecological validity often use naturalistic designs, include heterogeneous patient populations, and measure outcomes that reflect real-world functioning rather than just symptom reduction.
Usage
Usage note: Often discussed in contrast to internal validity in research methodology.
