Abstract
Background The Behaviour Change Intervention Ontology (BCIO) can be used to annotate reports of intervention evaluations for evidence synthesis. Such annotation requires a framework for entering and storing data (a ‘data schema’). This paper assessed the feasibility of using a prototype schema in a systematic review aimed at identifying promising behaviour change techniques (BCTS) to include in interventions designed to reduce speeding by motorists. Methods A systematic search identified randomised trials on interventions to reduce speeding through drivers’ ability and motivation. A prototype schema was created to annotate these papers, capturing information about Behaviour Change Techniques (BCTs), outcomes, and other study features. A team of annotators worked in pairs, independently annotating study reports before discussing their annotations to reach a consensus. The annotators noted issues concerning schema feasibility and identified gaps in the BCIO and possible associations between BCTs and outcomes. Results A total of twenty-nine eligible publications, encompassing 30 studies, were annotated, resulting in 88 study conditions and 2,097 individual annotations. The provided schema established a useful framework for categorising study features, although some inconsistencies and errors were noted in the annotations produced. Sixty BCIO classes effectively represented all but three of the annotated BCTS, yet none of the 70 behavioural outcomes were linked to ontology classes. The most frequently cited BCT in interventions was the provision of information regarding the adverse health effects of speeding, followed closely by BCTs offering feedback about speeding. The BCTs that were annotated as effective more often than ineffective involved devices and signage that delivered immediate feedback about speeding. Discussion A prototype schema for annotating behaviour-change intervention evaluations using BCIO could synthesise evidence on interventions to reduce speeding but needs a user interface for real-time validation. BCTs that raise immediate awareness of speeding are promising candidates for future interventions.
