[38] | What is the target population specifics? [7] | |
Suggested dimensions to consider | • The intervention core components, the specific active ingredients that make an EBI effective [7], fidelity consistent components [39] • The logic or theory that explains how the intervention is intended to work (i.e. the interventions’ deep structure [40], intervention strength [38] and program model [7]; its function [41]) • Components that are part of the intervention but not central for producing the outcomes (surface structure) [40] or adaptable periphery • Components, not part of the intervention: fidelity consistent [5, 7, 39], or fidelity inconsistent [39] • Components that make the intervention uniquely distinguishable (program differentiation) [2] | • Number, length and frequency of sessions, • Density: how the intervention is spaced out in time; the intensity of the intervention [28] • The quality of delivery [2, 4] • What the treatment provider plans and believes is delivered (dose delivered) • What the recipient perceives that they have received (dose received) [42] • The timing; when the various parts of the intervention is delivered in relation to the other parts [43] | • Format of delivery, e.g. one-to-one or group • Channels of delivery, e.g. phone, internet or face-to-face • Location of delivery, e.g. school, non-profit organization or church | • Interventionist specifics (e.g. who is delivering the intervention; their training, competence level; personal attributes and skills) • Setting, e.g. primary care, hospital, community-based, workplace-based [13] • Organizational factors, e.g. climate, leadership, mandate, history [44] • System characteristics, e.g. reimbursement models, contracts, laws, policies, regulations, political climate [44] | • The health conditions that the intervention targets • Cultural characteristics • Age groups (e.g., children, youth, adults) • Patient’s own health goals and specific needs • Comorbidities |
