Funded PhD Opportunity The effect of a school-based, peer-led walking intervention on well-being in adolescent girls
This opportunity is now closed.
Subject: Biomedical Sciences
Regular physical activity (PA) is associated with improved physical and mental health. Young people with sedentary lifestyles are at higher risk of mental illness. PA levels decline as children move into adolescence. Across the island of Ireland, participation in PA by girls is extremely low and Northern Ireland (NI) has the lowest proportion of children meeting current PA guidelines. Rates of mental illness in NI are also higher than in other parts of the UK with concerns about the transgenerational impact of the conflict on the mental health of future generations. Adolescence frequently marks the emergence of the first symptoms of depression and adolescent girls in NI are at high risk of self-harm and suicidal behaviour. There is also growing concern about the amount of time adolescents spend using mobile device and computer screens. Aside from the effect on sedentary behaviour, the impact of engagement with social media and other types of screen-time may have a negative impact on young peoples’ well-being. Initial studies show promising effects of PA interventions for increasing mental health in adolescents.
Aside from home, adolescents spend more time in school than in any other setting, so schools represent a key environment for promoting health-related behaviours and reduce the unintended health inequalities in interventions, as all adolescents can participate irrespective of socioeconomic status.
Following a systematic review of interventions in adolescents , we explored attitudes of adolescents to PA to inform the design of the peer-led, school-based walking intervention which was feasibility/pilot tested in Northern Ireland . Funding has recently been secured through Interreg as part of the CHITIN programme to conduct a fully powered trial of this intervention. This studentship will allow the inclusion of well-being outcomes within this trial and enable us to test the associations between these variables and sedentary screen-time. By including these novel and under-explored areas of wellbeing, these studies will generate novel impactful research outcomes.
Aim: This PhD will investigate the effects of a low-cost, peer-led, school-based intervention aimed at increasing PA on mental health, resilience and well-being in low-active adolescent girls.
· To undertake a systematic review of the effects of exercise on well-being in adolescent girls;
· To determine baseline levels of well-being in a sample of adolescent girls;
· To determine the effect of regular PA/ peer-led group based walking on well-being in adolescent girls and older peers.
Using a clustered RCT, adolescent girls (12-14yrs) will be recruited from 16 schools located across Northern Ireland and the border region of Ireland with 24 pupils per school being enrolled as participants. Post-baseline measures, schools will be randomised to control (n=8) or intervention (n=8). Intervention participants will have opportunities to participate in up to three 10-15min peer-led walks/day in school, led by older pupils (aged 16-18yrs) trained as walk-leaders. The intervention will be delivered across the school year with longer-term follow-up assessed.
Effectiveness will be determined by change in emotional regulation and well-being using validated self-report measures (e.g. The Regulation of Emotions Questionnaire and KIDSCREEN).
In addition to the publications included in the CHITIN funded project this PhD project would include at least 2 peer-reviewed publications, namely:
- A systematic review of the effects of exercise on well-being in adolescent girls;
- The findings of the RCT on the effects of the intervention on well-being in adolescent girls.
