Evaluation of a Worksite-Based Small Group Team Challenge to Increase Physical Activity

Physical activity virtual intervention for improving mental health among university students during the COVID-19 pandemic: A Co-creation process and evaluation using the Behavior Change Wheel

Background

During the COVID-19 pandemic, there were reductions in university students' physical activity, which further increased their mental distress, calling for technology-based physical activity interventions to address the challenges in delivering in-person interventions. This study aimed to develop a technology-based physical activity intervention and pilot test it.

Methods

We developed a virtually-delivered team-based physical activity challenge using the Behavior Change Wheel and Co-creation Framework based on Self-determination Theory. A pilot study was conducted in the evaluation phase to measure the recruitment rate, dropout rate, change in physical activity, and mental distress while identifying problems and collecting participants' opinions regarding the challenge. Wilcoxon signed-rank tests were conducted to assess the change in physical activity and mental distress. Qualitative data were analyzed using thematic analysis.

Results

A three-week physical activity challenge comprising five identified intervention functions was held with 480 participants. The recruitment rate was 84.8% resulting from 407 virtual challenge participants who were conveniently joined as research participants. The dropout rate for the pilot study was 10.96% resulting from the incompatibility problems with the application. Among sample participants who lacked physical activity, participation in this challenge improved their physical activity by 52.5 min of moderate-intensity physical activity per week and reduced their mental distress by three points of self-reporting questionnaire-20 score. Issues regarding the virtual application and the influence of participation in the challenge on basic psychological needs emerged. Participants' opinions identified lack of time as the main barrier to physical activity.

Conclusion

A co-created physical activity intervention developed using the Behavioral Change Wheel Framework inspired high interest from university students and may increase their physical activity and improve their mental health. Several suggestions were discussed to address the identified problems and improve the internal and external validity of the evaluation phase.

Effectiveness of Workplace Health Promotion (WHP) interventions in university employees: a scoping review

Workplace Health Promotion (WHP) interventions proved to be effective in several workplace contexts. Currently, the effectiveness of such interventions in the academic workplace is lacking, albeit evidence suggests similar patterns to those occurring in other workplace sectors. The aim of this study was to review WHP interventions in the university workplace that led to improve health- and work-related outcomes. Articles were selected using Pubmed, Web of Science, Scopus, Embase, PsycInfo, Cinhal and FSTA, using search strings focused on health- and/or work-related outcomes and involving University WHP interventions published between January 2010 and July 2021. The majority of the 12 studies selected reported positive results in their individuality, especially regarding health-related outcomes [biological such as weight loss, physical activity, mental health and lifestyle habits] and work-related outcomes concerning improvements either for the employee or for the working system. Studies on economic advantage and Return on Investment were limited and reported contrasting results. In conclusion, we have highlighted how the studies on effectiveness of WHP interventions in the university context are few and heterogeneous and need to be encouraged further research in order to build specific guidelines that are effective.

Choice architecture interventions to change physical activity and sedentary behavior: a systematic review of effects on intention, behavior and health outcomes during and after intervention

BACKGROUND

Choice architecture interventions, which subtly change the environment in which individuals make decisions, can be used to promote behavior change. This systematic review aimed to summarize studies on micro-environmental choice architecture interventions that encouraged physical activity or discouraged sedentary behavior in adults, and to describe the effectiveness of those interventions on these behaviors - and on related intentions or health outcomes - in presence of the intervention and after removal of the intervention (i.e. post-intervention, regardless of the time elapsed).

METHODS

We systematically searched PubMed, Embase, PsycINFO and the Cochrane Library for (quasi) experimental studies published up to December 2019 that evaluated the effect of choice architecture interventions on physical activity and sedentary behavior, as well as on intentions and health outcomes related to physical activity/sedentary behavior. Studies that combined choice architecture techniques with other behavior change techniques were excluded. All studies were screened for eligibility, relevant data was extracted and two independent reviewers assessed the methodological quality using the QualSyst tool.

RESULTS

Of the 9609 records initially identified, 88 studies met our eligibility criteria. Most studies (n = 70) were of high methodologic quality. Eighty-six studies targeted physical activity, predominantly stair use, whereas two studies targeted sedentary behavior, and one targeted both behaviors. Intervention techniques identified were prompting (n = 53), message framing (n = 24), social comparison (n = 12), feedback (n = 8), default change (n = 1) and anchoring (n = 1). In presence of the intervention, 68% of the studies reported an effect of choice architecture on behavior, whereas after removal of the intervention only 47% of the studies reported a significant effect. For all choice architecture techniques identified, except for message framing, the majority of studies reported a significant effect on behavioral intentions or behavior in presence of the intervention.

CONCLUSIONS

The results suggest that prompting can effectively encourage stair use in adults, especially in presence of a prompt. The effectiveness of the choice architecture techniques social influence, feedback, default change and anchoring cannot be assessed based on this review. More (controlled) studies are needed to assess the (sustained) effectiveness of choice architecture interventions on sedentary behavior and other types of physical activity than stair use.
