Table 3 Understanding interventions and strategies

Interventions are defined as “co-ordinated sets of activities designed to change specified behaviour patterns” [179]. Interventions are broad, typically comprising (1) the apparatus for delivering strategies, (2) strategies themselves and (3) the evaluation methods assessing their effectiveness [179]

Strategies are components of interventions and comprise the specific ‘active ingredients’ of an intervention [179]. This may include, for example, Behaviour Change Techniques (BCTs). BCTs and related strategies are those aspects within interventions which try to change behaviour in specific ways [179]
