Plain English Summary

Background and study aims
The immediate and future health benefits of regular physical activity (PA) are well established. Despite this, many children and adolescents on the island of Ireland fail to meet current PA recommendations. The transition from primary to second-level education represents a time when physical activity decreases, especially in adolescent girls. School-based activities that increase opportunities for PA are needed, particularly for those left out of other sporting activities because of the competitive selection process for school teams, and for types of activity that can be easily maintained into adulthood, such as walking.

Walking is a low-cost, effective means of increasing PA in adults and, after active play, is the greatest contributor to PA in children. It is the most prevalent PA among active adults. The potential of walking to promote PA in low-active adolescent girls encouraging a lifelong walking habit has not been explored. In addition, the school environment is an important health-promoting setting, overcoming many of the health inequalities found in other settings.

The study aims to assess the effectiveness of a low-cost school-based, peer-led brisk walking intervention in increasing PA in adolescent girls when delivered across the school year in a fully-powered trial in schools across Northern Ireland and the Border region of Ireland.

Who can participate?
All female pupils who attend a school selected to take part in the study and are aged 12-14 years (i.e. in Year 9 or 10 (NI) / First Year or Second Year (ROI) of post-primary education) will be invited to take part in this study. As this study aims to increase the amount of physical activity, only pupils who are healthy and free from any medical condition that may limit their ability to take part in a brisk walking programme will be eligible to take part in the study.

What does the study involve?
To assess the impact of this walking programme on physical activity and other factors, we would like to carry out a number of measurements at different time points throughout the study.

At baseline (week 0) we will take the first set of measurements in a semi-screened area. We will firstly measure height and weight, and then take measurements of waist and hip circumference. We will also ask participants to complete a series of questionnaires which will involve general questions about physical activity, as well as some scales to assess attitudes towards physical activity and walking. We will also collect some information on wellbeing, sleep and social media usage.

In the week before these measurements, we would like to collect some information about physical activity levels using a device known as an accelerometer. An accelerometer is a device that measures the amount and the direction of any activity that someone does. We will ask participants to wear this device for one week; it is small in size (about the size of a matchbox) and we will provide pupils with an information sheet on how to correctly wear the device. Participants will be asked to remove the accelerometer when bathing, taking part in water-based activities such as swimming and when asleep. This measurement of physical activity is non-invasive and will not impede on participants’ daily routine in any way.

Once our first set of measurements are complete, schools will be randomly allocated to either 1) the walking programme (intervention), or 2) continue with usual physical activity habits (control).

1. Walking intervention: If a school is randomly selected to take part in the walking programme, participants will have the opportunity to attend a number of group-led walks throughout the school week. These walks will be led by older students who have been trained as walk leaders and these older students will be under the supervision of a member of school staff. During the programme, participants will be encouraged to attend as many walking sessions as possible. The actual walking intervention will last a minimum of 20 and a maximum of 22 weeks.

2. Control group: If a school is randomly selected not to take part in the walking programme, pupils will not have to take part in any further physical activity as a result of this study. Although pupils will not take part in the walking programme, we will still collect take measurements at the time points outlined below.

Regardless of being assigned to either the intervention or control group, all participants will be involved in the study for approximately 1 year (to allow for follow up measurements), which will be conducted at a number of time points throughout the study.

Participants may be selected to take part in some evaluation work about the study. This is in the form of a focus group, which is an informal group discussion, where we would ask your participants to share their experiences of taking part in the walking programme. Participants will be randomly selected and asked to take part in the focus groups at the beginning and/or end of the intervention. The focus groups will discuss topics including physical activity, breaktime activities and social media.

What are the possible benefits and risks of participating?
We would hope that participants will enjoy taking part in this research study and find it a fun and enjoyable activity. Although participation in the study may not bring direct benefits to participants, the results of this study will help researchers further understand what approaches are useful when trying to encourage this age group to take part in more physical activity.

As with all physical activity, there is a minimal risk of injury or discomfort however walking is a very safe form of physical activity, and the walks not be performed at a high intensity. Risk assessments will be conducted at each school before the study takes place.

Study information

Scientific title

The Walking In ScHools (WISH) Trial: a cross-border trial to evaluate a walking intervention in adolescent girls.



Study hypothesis

To conduct a fully-powered clustered randomised controlled trial to evaluate the effectiveness of a novel, low-cost, peer-led school-based walking intervention, delivered across the school year, at increasing objectively measured PA levels of adolescent girls in schools within NI and the border counties of Ireland.

It is hypothesised that intervention participants will increase daily physical activity and reduce time spent sedentary by replacing sedentary behaviour with walking.

Physical activity


Schools will be randomised to either receive the walking intervention, or to act as controls.
Following baseline measurements, the intervention will be delivered for the whole school year. Allowing for holidays, exams, educational trips and other school events this will vary from one school to another however the minimum intervention will be a minimum 20 and a maximum of 22 weeks.

INTERVENTION: In intervention schools, female pupils (identified by school staff) aged 16-18yrs (peer role models) will be trained as walk leaders to lead younger pupils (aged 12-14rs) in 10-15 min walks before school and at break and lunch recess. All walks will occur in school grounds and pupils will be encouraged to participate in many walks as possible each week. Reward cards, stamped for each walk completed and exchanged for small rewards with low monetary value will be used for self-monitoring. Walking routes will be pre-determined and a risk assessment will be completed for each school site. Peer walk leaders will be trained to ensure they consider safety concerns of facilitating the walks and the training programme will emphasize the importance of the walks being performed at a brisk pace, i.e. at a pace sufficient to elicit moderate intensity PA in participants. Training will also include information on providing and encouraging social support amongst participants to align with Self Determination Theory (SDT). Two walk leaders will accompany each walk, one at the front and one at the back of the group. Leaders will set the pace of the walk and ensure the safety of pupils. Walks will take place in a one of the pre-planned routes around the school grounds. At the end of each walk, walk leaders will stamp each participants’ card and note attendees to monitor compliance with the intervention.

As part of the social support component of the intervention, participants and walk leaders will be invited to be part of separate closed social media groups designed to include opportunities for social support in the form of capabilities to share progress with friends. In addition, social support and encouragement to continue to participate will be provided to participants via weekly updates which will include: strategies to address barriers and recognize progress; links to websites and resources; and vignettes of support and advice from others who have successfully increased their physical activity levels. These pages will only be accessible to those in the intervention and will be moderated by named members of the research team to ensure data protection.

CONTROL: During the intervention period, schools (and participants) in the control group will be instructed to continue with their normal PA habits.
