Congratulations to our PhD Student Sian Calvert on publishing the first paper from her PhD research, a systematic review in the leading journal Obesity Reviews! Sian, supervised by Dr Robert Dempsey and Dr Rachel Povey, is one of a number of PhD students based in the Staffordshire Centre for Psychological Research at Staffordshire University.
Sian’s PhD programme, which funded by the University, aims to develop and test the feasibility of conducting a Social Norms Approach intervention with high school students to improve adolescents’ eating behaviours by challenging some of the misperceptions of the acceptability and amount of healthy foodstuffs eaten by their fellow student peers. The Social Norms Approach is a means of promoting healthier behaviours based on informational feedback which challenges common misperceptions (i.e. the over- and under-estimation of peer behaviours) to reduce the perceived social pressure to conform to potentially unhealthy norms. Sian’s primary supervisor, Dr Robert Dempsey, leads a programme of research evaluating the Social Norms Approach at Staffordshire University and has recently published a critical review of the use of the approach as a health behaviour approach (click here to read this review).
Sian’s paper, a systematic review of the use of in-school interventions to promote healthier eating amongst 11-16 year olds, is the first to evaluate the range, format and outcomes of healthy eating interventions delivered in high school settings in the UK and around the world. The start of secondary education (or its equivalent in non-UK countries) marks a time where many students become more independent, have greater control over their dietary behaviours, and is a key period where dietary habits can form which last into adulthood. Also, there are numerous reports of increases in unhealthy eating behaviours (e.g. snacking, meal-skipping) and decreases in more healthy eating behaviours (e.g. fruit and vegetable consumption, drinking regular amounts of water) amongst this age group. The high school environment forms a key target for dietary behaviour interventions given that schools have extensive contact with students, that the school environment is relatively well controlled (meaning that interventions can be appropriately tested and controlled), and behaviours can be monitored. Sian’s review makes several recommendations for future best practice with this group of individuals, including the need for future interventions to consider the influence of peers on dietary behaviours (e.g. by including student peers in intervention campaigns and activities) as well as better evaluating the potential role of personalised, individual, feedback on dietary behaviour choices.
Dr Robert Dempsey, Sian’s supervisor, commented:
“Sian did a great job reviewing a complex and very varied literature, and this systematic review is a key part of her PhD research which has directly informed the follow-up studies she is currently analysing and writing up. To publish her work in a very competitive and highly ranked global journal before the completion of her PhD studies is a great achievement for Sian!”
Sian is currently analysing and writing up a series of qualitative and quantitative papers based on her PhD studies investigating the feasibility of the Social Norms Approach as a means of encouraging more positive healthy behaviours amongst high school students.
