Adolescent Anti-Social behaviour is viewed as a normative part of the developmental process. That said, the outcomes of such behaviour on a young person’s future, although varying in severity, are often negative. The many factors which lead to a young person taking part in anti-social behaviour differ between individuals and groups. This project, through collaboration with local services, aims to investigate the decision to take part, the factors which are involved in this decision both for individual adolescents and groups and whether this decision can be altered using an intervention designed to impact upon an individual’s uniqueness.

My PhD thesis seeks to examine if there is a direct causal association between our friends genes and our own risk for psychiatric outcomes like depression, independent of our own genetic makeup. I will also examine if this mechanism is involved in building resilience, and if it generalises to on-line social networks as well as off-line social networks.

Currently there are effective psychological treatments for depression available, but we still do not know how and why these treatments work. Consequently, I will be using secondary data to investigate the processes that are related to patterns of depression symptom change within Cognitive Behavioural Therapy and Behavioural Activation.

My research looks at whether a simple computer game can help children to make healthier decisions when choosing what to eat. Inhibitory control training (ICT) involves making quick motor responses (keyboard presses) to pictures of food unless a “stop” signal is presented at the same time. When these signals are presented consistently with images of unhealthy snacks (chocolate, sweets, biscuits), training can lead to automatic food-stop associations that reduce selection and intake of these foods. This project aims to determine the conditions under which ICT is most effective on improving child food choices.
