Official title: Are You Daydreaming? Co-creation to Promote Healthy Sleep in Adolescents in a School Context: a Health CASCADE Protocol

Health CASCADE (Marie Skłodowska-Curie grant agreement n° 956501) aims to address complex public health problems by making co-creation a scientifically sound methodology, aided by evidence-based methods, practices, and technologies. The current study, which focuses on co-creation in the school context is part of this overarching European project.

Healthy sleep is important for adolescents' mental and physical health and cognitive functioning. However, sleep difficulties are among the top three health complaints in European adolescents. This indicates a need for successful interventions.

Co-creation is a promising approach to design tailored interventions. By actively involving all relevant stakeholders, co-creation has been shown to increase self-efficacy, self-consciousness, empowerment, and feelings of ownership. However, co-created interventions are localized and therefore less generalizable to a broader population. Moreover, the process is very time- and cost- consuming. To make co-creation more feasible, research should focus on the upscaling of existing interventions. The investigators propose that the co-creation process is still absolutely vital for intervention success but that it can be shortened.

The investigators aim to scale up an existing intervention to promote healthy sleep. This existing intervention was developed using co-creation together with the target group (adolescents aged 13 to 15) and parents, and implemented with support of teachers and fellow students. To investigate whether the shorter co-creation process is needed in order to scale up the intervention to another setting and context, the investigators will use a three-arm cluster controlled trial. This will include one co-creation intervention school, one standard implementation school (this school receives the existing intervention without a shortened co-creation process), and one control school. The co-creation process will be structured by using the Intervention Mapping Protocol to ensure an evidence-based framework. The effect of the intervention will be evaluated using actigraphy and questionnaires, while the process will be evaluated using questionnaires, interviews, and focus groups.

Read the detailed description

The aim of this study is to scale up an existing sleep intervention (co-created with adolescents and parents, and implemented with the support of teachers and fellow students) in Flanders to improve sleeping behavior. Scaling up an intervention is defined as transferring an intervention to another context, setting, and group. As co-created interventions are localized by nature, the researchers will investigate whether this existing intervention can be scaled up to a new context, setting, and group while the aim of the intervention remains the same, i.e., improving healthy sleeping behavior in adolescents. To test this, a co-creation school, standard implementation school, and control school will be recruited. Below, the investigators will describe what will be expected from each condition.

Co-creation school: Scaling up the existing sleep intervention to a new context, setting, and group will proceed in the co-creation school. The existing intervention will be adapted to the culture of this school, based on students', school staff's, and parents' perspective on the health problem (unhealthy sleeping behavior in adolescents) and thoughts on the components of the existing intervention. To adapt the existing sleep intervention, action groups will be composed. Every action group contains a maximum of 10 individuals.

  • Action group adolescents: This action group consists of a maximum of 10 students from the 6th and 7th grade (1st grade secondary school, Belgian school system). The participants will be involved in the adaptation of existing intervention components. Furthermore, participants will implement the adapted intervention at school.
  • Action group school staff: This action group consists of a maximum of 10 individuals working at the co-creation school. Participants will be involved in designing an implementation plan for the intervention. Moreover, participants will be asked to check the adapted components for feasibility.
  • Action group parents: This action group consists of a maximum of 10 parents who have at least one child in the 6th or 7th grade of the co-creation school. Parents will be involved in the adaptation of the parental intervention components of the existing intervention.
  • Co-facilitators: Students of the 12th grade (year 6 secondary school, Belgian school system) will be involved as co-facilitators. This means that the students of the 12th grade will facilitate the co-creation sessions designed for the students of the 6th and 7th grade together with the researchers.

Standard implementation school: To test the added value of the shortened co-creation process and to show that this process is needed to build ownership and empowerment, the existing sleep intervention will be implemented without the shortened co-creation process. The standard implementation school will be provided with a manual and a training about the implementation of the intervention.

Control school: To test the overall effect of the intervention a control group is needed. None of the interventions will be implemented at the control school and therefore the school staff do not have to take part in the measurements.

In total, the intervention in both the co-creation school and the standard implementation school will take 9 weeks.

Effect evaluation: To test the effect of the intervention, students (n = 378, based on a power analysis performed in R) will be invited to take part in three measurements (baseline, posttest (after the intervention), and follow-up (sixth months after the end of the intervention)) in all three arms. For members of the action group, a fourth measure will be administered (in-between baseline and posttest) to investigate whether the co-creation process itself can lead to changes in specific variables (see measures section). In order to compare the co-creation process to a standard implementation training, this fourth measurement will also be assessed among individuals involved in the implementation in the standard implementation school. To objectively measure sleep, participants will be asked to wear a GENEActiv device for 7 consecutive days at each of the three measurement points. Furthermore, participants will be invited to complete a questionnaire. This questionnaire will consist of questions about sleep duration, sleep quality, daytime sleepiness, sleep hygiene, determinants of sleeping behavior (knowledge, attitude, self-efficacy specifically related to sleeping behavior, social influence and social support, barriers), mental wellbeing, and feelings of empowerment and ownership. Furthermore, SES, puberty, and BMI will be assessed as important covariates. For students who are part of the action group (in the co-creation school) the questionnaire will also contain questions about general self-efficacy, and self-esteem. Moreover, students who are part of the action group will be invited to complete the whole questionnaire at one additional time point, namely after the shortened co-creation process. This measurement will enable us to investigate whether students in the action group experience more general self-efficacy and feelings of self-esteem as a result of participation in the co-creation process. Parents (ideally n = 378, one parent of each participating student) will be invited to complete questionnaires at the same measurement points as the students in all three arms. Parents' questionnaire will contain questions about knowledge and attitude about sleep, whether parents impose bedtime rules on children or have other supportive strategies, and questions regarding self-efficacy in engaging in these supportive strategies. Completion of questionnaires for students will take about one lesson (40-50 minutes). For parents, completion will take about 15 minutes.

Process evaluation: To evaluate the co-creation process as well as the implementation of the intervention, the investigators will use questionnaires, interviews, and focus groups. Students and parents from the action group will be asked to provide a short evaluation after every co-creation session. More extensive evaluations (focus group) will take place half-way during the development of the intervention, once the adaptation of the intervention is finished, and after the implementation of the intervention is done. Fellow students and parents, who are not part of the action group will be asked to evaluate the implementation of the intervention as well, using a short questionnaire. Students will also be invited to take part in focus groups. School staff (co-creation arm and standard implementation arm) will be invited to complete a questionnaire measuring motivation, empowerment, barriers for implementation, and general knowledge about sleep at three time points (baseline, pre-implementation, and after the intervention). Completion of questionnaires for school staff will take about 30 minutes. Moreover, school staff will be invited to take part in focus groups as well. These will take place at the same time points as for the students. Focus groups will take around 50 minutes (one lesson).
