We find that, acrossdomains, interventions designed to change individual determinantscan be ordered by increasing impact as those targeting knowledge,general skills, general attitudes, beliefs, emotions, behavioural skills,behavioural attitudes and habits. Interventions designed to changesocial-structural determinants can be ordered by increasing impactas legal and administrative sanctions; programmes that increaseinstitutional trustworthiness; interventions to change injunctivenorms; monitors and reminders; descriptive norm interventions;material incentives; social support provision; and policies that increaseaccess to a particular behaviour. We find similar patterns for health andenvironmental behavioural change specifically. Thus, policymakersshould focus on interventions that enable individuals to circumventobstacles to enacting desirable behaviours rather than targeting salientbut ineffective determinants of behaviour such as knowledge andbeliefs.
