High Fidelity: Translating the evidence-base into real world settings
Dr Jo Holliday, Research Fellow, Cardiff University
Potential conflict of interest: Sally Good is the Chief Operating Officer at DECIPHer Impact Ltd, a not-for-profit company wholly owned by the Universities of Bristol and Cardiff set up to licence and support the implementation of effective health promotion interventions.
Background
Health promotion interventions inherently complex
Background
Health promotion interventions inherently complex
Presents challenges for standardization of delivery evaluation
Pragmatic trials incorporating process evaluation can provide insight into where variation occurs why it occurs and implications of this for wider implementation
Aims of study Discuss issues of fidelity of intervention delivery
encountered within A Stop Smoking in Schools Trial (ASSIST)
Describe the systems established to ensure translation of positive trial findings into real-world settings.
The ASSIST Programme
A school-based, peer-led smoking prevention programme Encourages new norms of smoking behaviour by training
influential Year 8 students to work as ‘peer supporters’ Peer supporters identified as influential by peer group Peer supporters trained during school time but off school site Peer supporters have informal conversations with other
students Support sessions held in school
Evaluation of the ASSIST Programme Evaluated in a pragmatic RCT with integral process evaluation Involved 10,720 students from 59 schools at baseline
Demonstrated a 22 % reduction in the odds of being a regular smoker in intervention schools compared with control schools (Odds ratio 0.78 CI: 0.64-0.96) using follow- up data collected at three time points over two years
MethodsStage Source Method and numberPeer nomination Researchers and sessional staff
involved in administration of peer nomination questionnaire in 30 intervention schools
Self-complete questionnaires (n= 319)
Peer supporter recruitment, training and follow-up sessions
Two researchers in four schools selected for in-depth process evaluation
Trainers who conducted the recruitment meeting, training and follow-up sessions in 30 intervention schools
