Background: The need for effective, low-cost and evidence-based tools to prevent illness and promote health in the population is paramount. Norway, along with other countries in the Western world, is currently facing major health and welfare-related challenges. Demographic changes, lifestyle related diseases and work absence are threatening the sustainability of the Norwegian welfare state. Non-communicable diseases, including mental illness, currently account for 65% of the total disease burden in Norway and 50% of Norwegians are likely to meet diagnostic criteria for a mental disorder some time during their life span. Traditional treatment and care options tend to be costly and time consuming, and to depend on highly skilled specialist human resources. Systematic findings also indicate that population-based (i.e., universal, targeting the general population) measures often result in larger population health gains than selective and indicated measures targeting only those with excess risk. According to the paradox of prevention, when disease risk is common, universal interventions directed towards the whole population before illness occurs, are more effective than interventions targeting high risk groups after symptoms have emerged. The Covid-19 pandemic and associated social distancing measures have corroborated the need for digital solutions. Web-based interventions may reach a large number of participants, utilizing a very modest amount of both human and financial resources. The aim: This study aims to test a potentially effective low-cost health and wellbeing promotive web-based intervention targeting the general population in Norwegian municipalities. The intervention is based on the Five Ways to Wellbeing framework developed for British health authorities in 2008. This framework, and the intervention to be tested, provides participants with knowledge on simple, sustainable activities that may strengthen their subjective wellbeing (SWB), mastery, health and social relations, thereby also reducing the risk of common mental health problems such as depression and anxiety. The study will be conducted in close collaboration with municipal stakeholders and important user groups. Thus, the principal investigator (PI) will investigate effects of a low-cost health and wellbeing promotive public health tool based on the evidence-base of Five Ways to Wellbeing. To date, nobody has tested the Five Ways-concept in such a format. Proved effective, this web-based 5WaysA intervention, may have a significant impact on the public health of inhabitants in the municipalities. Main hypothesis: The web-based intervention 5WaysA will improve wellbeing and mastery and hence provide the municipalities with an effective measure for mental health promotion. Research questions: To what extent does participation in the web-based 5WaysA intervention lead to improved wellbeing, mental health and mastery in the general population? To what extent are the effects short-term and long-term (i.e., 10 weeks and 12 months)? What mechanisms explain potential improvements in wellbeing? For whom is this intervention effective (i.e., is the effect moderated by e.g. gender, age, education)? What mechanisms (e.g., regular practicing of 5Ways actions, increased social activity or support) explain intervention effects? Sample and recruitment: The PI plan to recruit a minimum of 1500 participants from the general population in Norwegian municipalities. The participants will be randomized to either an intervention group (n=750), or to one of two wait-list control groups (active control, n=375) (inactive control, n =375). The wait-list control groups will receive the intervention five months later. The PI expect high drop-out (up to 50 %) since this has been the situation in other studies investigating online interventions in a general population. The PI is also unsure about how much time the municipalities have to help PI with the recruitment process, because of a high work load in the municipalities during the pandemic of Covid-19. If the PI do not get enough participant, or if the pandemic makes in difficult to interpretate the results (an extraordinary historical event), PI will try to do another round of the same study in the autumn of 2021. This will be registered by the PI as an new trail if it takes place. Procedures: The web-based 10 week intervention consist of one main webinar (two hours at Zoom), a booster session webinar five weeks later and SMS messages twice a week in the the six following weeks. The webinars will be live lectures with an independent trained facilitator. The SMS messages will be sent out by the PI (via Nettskjema) to all participants while they are in the interventions period. Questionnaires will be administrated and distributed by the PI by using the Nettskjema and Services for sensitive data (TSD) tools. The measurements will also be conducted use of Nettskjema and TSD. Power analysis: The PI assume that we can recruit a minimum of 1500 participants, but high drop-out is expected. An a priori power analysis was conducted using G*Power3 to test the interaction effect in a mixed ANOVA, using a two-tailed test, assuming a small effect size (f = .10), and an alpha of .05. The assumed effect size (f=0.1) was chosen as it is of the same magnitude (lower bound) as has been reported by other universal interventions with wellbeing as the outcome measure. The result showed that if PI attained a total sample of 750 participants at the second measurement point (attrition of 50%), PI would have power of .999 to detect a group by time interaction. The high level of statistical power will enable PI to investigate both moderators and mediators of the treatment effect.
