Consciousness raising (CR), dramatic relief (DR), environmental reevaluation (ER), social-liberation (SO), self-reevaluation (SR), counter conditioning (CC), helping relationships (HR), reinforcement management (RM), stimulus control (SC) and self-liberation (SL). ω2 < 0 were set to 0; effect size (ES): small ES 0.01; medium ES 0.059; large ES 0.139; ✓ indicates agreement with initial prediction. *No revisions made to ES diet-based prediction. Proposed revised predictions are based on results as well as cross-sectional data from a separate sample.
