Hypothesized moderator | Possible categories for analysis |
|---|---|
Study design | Randomized vs. all other designs |
Sex ratio of subjects | 0–30% female vs. 30–70% female vs. 70–100% female |
Psychological theory/theories underlying the intervention | Mind attribution vs. disgust vs. social norms, etc. |
Intensiveness of intervention | Total length of time subjects are exposed to intervention |
Length of follow-up between intervention and outcome measurement | Days (continuous) or > 1 day vs. ≤ 1 day |
Proximity of the outcome measure to actual meat consumption or purchase | Behaviorally measured vs. self-reported vs. intended consumption or purchase |
Scope of meat outcome | All-meat consumption vs. any subset of meats (where studies excluding seafood consumption will be in the latter category) |
