Review, development and manualisation of the One Body One Life (OBOL) Family Weight Management programme, using the Behaviour Change Taxonomy V.1

Coventry City Council delivers wellbeing interventions and tier 2 weight management interventions through their 'Be Active Be Healthy' service. In line with NICE guidance on behaviour change, Coventry University was commissioned to work in partnership with CCC to ensure that BABH's services are grounded in the latest theory and evidence on effective behaviour change.A review of the group-based, 10 week structured family programme 'One Body One Life' (OBOL) was undertaken to identify what behaviour change technique were currently included in the programme. Content from programme materials, structured discussions with the OBOL facilitators and observations of programme delivery were coded for behaviour change techniques (BCTs) using the Behaviour Change Technique Taxonomy V1. Simultaneously, a review was undertaken of current evidence for effective interventions similar to OBOL to identify which BCTs are likely to be most effective. The OBOL programme was re-designed through a collaborative process between the research team and OBOL facilitators to improve the quality of both the content and delivery mechanisms, according to evidence-based behaviour change theory, while ensuring it meets the needs of its target populations. A detailed intervention manual was developed which provides instruction on how to effectively deliver included BCTs. Bespoke training was delivered to the OBOL facilitators on the following topics; behaviour change theories; intervention development; behaviour change techniques; delivering BCTs. The re-designed programme will be delivered in September 2016 and will be observed and coded using the BCT taxonomy to determine intervention fidelity, alongside a revised evaluation and monitoring framework to assess effectiveness.
