Adherence
Psychosocial interventions targeting habit, motivation, beliefs about capabilities, and knowledge are more effective for predicting fruit and vegetable intake than those relying on multicomponent theoretical frameworks.
To improve fruit and vegetable intake, interventions should focus on building habits, enhancing motivation, setting clear goals, and boosting confidence in one's ability (self-efficacy) to eat them. Avoid overly complex programs that try to integrate too many psychological theories at once; stick to proven, single-theory frameworks like the Theory of Planned Behavior.
The most consistent variables associated with the prediction of FVI (at least 50% of time) were habit, motivation and goals, beliefs about capabilities and knowledge... Our results suggest that using a multicomponent theoretical framework performed significantly less well than using constructs from only one theory.
