Brief summary

The purpose of this study is to evaluate the effectiveness of a digital health behaviour change intervention in promoting ergonomic ways of using technology to children aged 11 to 14 years in Australia. Specifically, it aims to determine if the resource can be effective in improving children's knowledge, attitude, subjective norms, perceived behavioural control, and behaviours relating to ergonomic use of technology. A cluster group, two-arm trial will be conducted to determine the effectiveness of the resource. Study hypothesis: The use of a digital intervention can improve children's ergonomic behaviours when using technologies.

Interventions

The digital health promotion intervention, called TECHgonomics, is a web-based digital health promotion resource that has been developed in Australia for children aged 12 to 13 years, to promote ergonomic ways of using technology. Development of this resource was informed by a combination of evidence-based strategies reported in the research literature and a co-design approach with Year 7 school children in Perth, Western Australia. The resource comprises three modules and contains the following

The digital health promotion intervention, called TECHgonomics, is a web-based digital health promotion resource that has been developed in Australia for children aged 12 to 13 years, to promote ergonomic ways of using technology. Development of this resource was informed by a combination of evidence-based strategies reported in the research literature and a co-design approach with Year 7 school children in Perth, Western Australia. The resource comprises three modules and contains the following features: 1. Learning components comprised of role model videos, written information, and images 2. Interactive quizzes 3. Leaderboard 4. Interactive body charts indicating common areas of pain/discomfort 5. Discussion blog 6. Ergonomic diary for self-monitoring of ergonomic ways of using technology A controlled trial will be used to determine the effectiveness of the TECHgonomics digital health promotion resource in improving children's knowledge, attitude, subjective norms, perceived behavioural control, and behaviours relating to ergonomic ways to use ICT. The trial will be a cluster group, two-arm trial, in which outcomes for participants in the intervention group will be compared to outcomes for participants in the control group. Participants in the intervention group will be from one co-educational high school while participants in the control group will be from another co-educational high school, to reduce the risk of contamination. Participants in the intervention group will be given access to use the TECHgonomics digital health promotion resource at school and/or at home for 8 weeks, while the control group will not be given access to use the resource during the study period. Outcomes of knowledge, attitude, subjective norms, perceived behavioural control, and behaviours will be measured at baseline (T1) prior to the commencement of the trial and post-assessment (T2) at the end of the 8-week trial period. Demographic information, including age, gender, residential postcode (to determine socioeconomic status), and school year level for all participants will also be collected at baseline. The trial will take place over 8 weeks from August 2021 to October 2021. Participants will be asked to spend 30 mins every week at school and/or at home over 8 weeks to use the digital health promotion resource. Adherence to the intervention will be monitored using website data analytics.
