| Concept | Core claim | Strength | Weakness |
|---|---|---|---|
| Biomedical | Health = absence of disease | Precise, measurable | Ignores mental and social; over‑medicalises |
| Ecological | Health = dynamic equilibrium between people and environment | Explains environmental disease | Hard to operationalise |
| Psychosocial | Health shaped by social, psychological, cultural factors | Captures behaviour and stress | Vague endpoints |
| Holistic | Synthesis of all of the above | Matches lived reality | Broad |
