The BCIO currently contains more than 1000 entities but this represents a relatively small proportion of those that will be needed to cover the field of behavioural science. There is an ongoing programme to extend and update the BCIO and it is hoped that the behavioural science community will get involved in this exercise.

Currently, this includes entities relating to:

1.Interventions aimed at influencing behaviour, including their content and delivery (e.g., licensed nicotine replacement product)

2.Engagement with the interventions (e.g., percent using the nicotine product as recommended)

3.Populations that an intervention may target (e.g., cigarette smokers in the UK aged 18+ years who have been smoking)

4.Settings in which interventions may be delivered (e.g., general practice facilities in the UK)

5.Events that may be taking place at the time of the intervention (e.g., Covid-19 pandemic)

6.The target behaviour (e.g., smoking cessation for 6 months)

7.The value of outcomes in terms of the target behaviour (e.g., 10 percent)

8.Mechanism of action by which interventions may influence behaviour (e.g., reduction in craving and nicotine withdrawal symptoms)

9.Research studies evaluating behaviour change interventions (e.g. study arm in a randomised controlled trial. biochemical verification of abstinence)
