Q

sociological perspectives on needs (Bradshaw’s needs)

Q

Bradford Hill causality criteria

A

1) temporality = exposure occurs before outcome
2) dose response = more exposure = inc risk of outcome
3) strength = stronger association (relative risk) = less chance due to something else
4) reversibility = take away exposure = reduces risk of outcome
5) consistency = pattern seen in different study types and different backgrounds/communities (reproducible)
6) plausibility = existence of a mechanism to explain cause and effect
7) coherence = consistency with other info
8) analogy = similarity with other cause/effect relationships
9) specificity = relationship is specific to outcome of interest
