Research Context

This project involves three workstreams (WS).

WS1 aims to identify interpersonal and organisational factors that influence the confidence and motivation of first responders to investigate coercive control. Using a longitudinal, multi-levelled design, the study will be able to isolate the effect of change in interpersonal and organisational factors on officer confidence and motivation.

WS2 will involve a parallel qualitative longitudinal investigation of how officers feel about the investigation of coercive control and how organisational factors, such as force resource support, can affect an individual's ability to investigate cases of coercive control.

WS3 will use force-level data on recorded crimes, arrests and outcomes (charges/summons) to estimate the effectiveness of the training in Hampshire and other forces compared to forces that have not undergone the training. This is a pre-registered quasi-experiment: https://osf.io/vx789/registrations
