Help Overcoming Pain Early - an Adolescent-centered School Health Prevention Program

School nurses who perform the person-centered health dialogues with the students will have an education, which includes a various of lectures about person-centered health dialogues, stress/pain management and school nurses (over-)generalizations of gender. The project has a hybrid design, which means that outcomes of the intervention and the evaluation of the implementation are taking place in the same data collection. All students at the participating schools who fulfill the criteria of chronic pain that is mediated by stress, will be invited to participate in the intervention. The participants will be randomized to either group A or group B. Participants will once report frequency, duration and intensity of pain and they also fill in the questionnaire Center for Epidemiologic Studies Depression Scale for Children. In the first period of data collection, the group A will get four sessions of person-centered health dialogues. The sessions also include pain/stress management and education about stress and pain (the HOPE model that is an adolescent-centered school health prevention program when adolescents have chronic pain). Group B will be a control group. All participating school nurses and students will be interviewed about their experiences of the intervention. In the second period of data collection it will be the other way around, i.e., group B will will get four sessions of person-centered health dialogues. The sessions also include pain/stress management and education about stress and pain (the HOPE model that is an adolescent-centered school health prevention program when adolescents have chronic pain). Group A will be the control group. All participating school nurses and students will once again be interviewed about their experiences of the intervention. The primary outcome in the intervention is self-efficacy and this outcome will be measured before and after the intervention in both group A and group B. Secondary outcomes are self-rated health, quality of sleep, pain intensity, and school attendance and these outcomes will also be measured before and after the intervention in both group A and group B.
