Mixed-methods process evaluation of the EACH-B intervention in UK secondary schools: Delivery fidelity, stakeholder responses and contextual influences.

ABSTRACT:

Background

The Engaging Adolescents in Changing Behaviour trial tested the impact of an adolescent diet and physical activity intervention involving: teacher training in Healthy Conversation Skills, a health education module (LifeLab) and a gamified smartphone application ('the app'). The process evaluation described in this paper examined the implementation, context and mechanisms of impact of the intervention (the core elements of the Medical Research Council guidance on process evaluation of complex interventions), to identify how and why participants did or did not engage with each element of the trial and the intervention.

Methods

A mixed-methods approach was employed. 51 interviews with students, teachers and parents from 11 secondary schools were conducted and analyse
