Table 1 Terms and definitions adopted for the current review
Term | Definition |
|---|---|
Behaviour change technique | “An observable, replicable, and irreducible component of an intervention designed to alter or redirect causal processes that regulate behaviour; that is, a technique that is proposed to be an ‘active ingredient’” [13]. |
Fidelity | “The extent to which the intervention is delivered as intended” [8]. |
Staff training | Any set of activities aimed at changing teaching practice(s). |
Activity behaviour | Any activity behaviour across the intensity spectrum, including physical activity and sedentary behaviour [20]. |
Physical activity | “Any body movement generated by the contraction of skeletal muscles that raises energy expenditure above resting metabolic rate. It is characterised by its modality, frequency, intensity, duration, and context of practice” [21]. |
Sedentary behaviour | “Any waking behaviours characterised by an energy expenditure ≤1.5 metabolic equivalent of tasks, while in a sitting, reclining, or lying posture” [22]. |
An intervention | Single or multiple components (e.g. contents and/or design features) of a programme that aim to effect one or more changes in a defined group of participants (e.g. school staff, students, parents). |
A study | “A defined group of participants and one or more interventions and outcomes”. A study may have more than one output, peer-reviewed or otherwise, to report information about the protocol, analysis plan, process evaluation or observed outcomes [23]. |
