Video NET With CYP Who Witnessed Domestic Violence

The purpose of the study is to investigate the potential effectiveness, feasibility, acceptability and putative mechanisms of change of video NET with children and young people who witnessed domestic violence. The primary objective of the study is to evaluate whether video NET can reduce PTS in this group. The secondary objectives of the study are: * To determine whether video NET can also impact on general psychological distress and functioning; * To examine the putative mechanisms of change within NET, i.e. habituation and integration of trauma memories; * To explore the feasibility and acceptability of video NET.
