Development of an Online Mind-Body Physical Activity Intervention for Young Adults during COVID-19: A Pilot Study

A systematic review on the effectiveness of unstandardized mindfulness interventions in improving dietary and physical activity outcomes in healthy adults

BACKGROUND

Mindfulness-based strategies are increasingly applied outside of standardized clinical protocols to promote healthy lifestyle behaviors. No overview exists of how mindfulness-based strategies are integrated in these "unstandardized" interventions and which strategies have potential for effect. This review (i) summarizes key intervention characteristics and strategies, (ii) provides a qualitative overview of the effectiveness of unstandardized mindfulness-based strategies for promoting healthy dietary and PA behaviors, and (iii) provides an assessment of the study quality.

METHODS

Articles were identified using the PubMed, PsycINFO, and Web of Science online databases until 11/2024. Records were included if they applied mindfulness outside of a standardized clinical protocol among healthy adults and measured healthy dietary or PA outcomes pre- and post-intervention. Study quality was assessed using the Effective Public Health Practice Project tool.

RESULTS

Interventions (n = 44) inconsistently applied formal and informal mindfulness strategies and a variety of meditation exercises (e.g., body-centered or movement meditation). The findings did not provide clear evidence in favor of unstandardized mindfulness applications in promoting dietary behaviors and PA at the between-group level. Study quality was predominantly rated as 'weak' due to selection bias and lacking blinding procedures.

DISCUSSION

There exist great variations in the implementation of mindfulness strategies, low study quality, and heterogeneity in measurement, potentially explaining the lack of effects of such unstandardized interventions. To gain more insight into the effective application of mindfulness-based strategies in health promotion, higher-quality studies with robust designs as well as component studies are needed to shed light on the active ingredients of interventions.

The Reach, Effectiveness, Adoption, Implementation, and Maintenance of Digital Mental Health Interventions for College Students: A Systematic Review

PURPOSE OF REVIEW

We evaluated the impact of digital mental health interventions (DMHIs) for college students. We organized findings using the RE-AIM framework to include reach, effectiveness, adoption, implementation, and maintenance.

RECENT FINDINGS

We conducted a systematic literature review of recent findings from 2019-2024. Our search identified 2,701 articles, of which 95 met inclusion criteria. In the reach domain, student samples were overwhelmingly female and White. In the effectiveness domain, over 80% of DMHIs were effective or partially effective at reducing their primary outcome. In the adoption domain, studies reported modest uptake for DMHIs. In the implementation and maintenance domains, studies reported high adherence rates to DMHI content. While recruitment methods were commonly reported, adaptations and costs of implementation and maintenance were rarely reported. DMHIs for college students are effective for many psychological outcomes. Future work should address diversifying samples and considering implementation in a variety of college settings.

The effectiveness of physical activity interventions in improving higher education students' mental health: A systematic review

Traditional interventions aiming to improve students' mental health and quality of life include meditation or canine therapy. The development of physical activity-related interventions has increased over the past decade. We aimed to review all studies using physical activity for improving the mental health and quality of life in higher education students whilst describing the interventions, measurements and effectiveness. A systematic search of six electronic databases including: ProQuest, MEDLINE, Embase, CINAHL, SPORTDiscus and CENTRAL, was conducted following PRISMA guidelines. Randomized or non-randomized controlled trial physical activity-related interventions involving higher education students aiming to improve their mental health and quality of life were included. Searches yielded 58 articles with interventions involving martial arts, sport, mind-body exercises and anaerobic exercises. Psychological measures varied across studies including the State Trait Anxiety Inventory, Beck Depression Inventory and the Perceived Stress Scale. Over half of the studies included in this review (n = 36) were effective in improving students' mental health or quality of life. Findings from our review suggest that interventions aiming to be effective in improving students' mental health quality of life should aim to deliver moderate-vigorous intensity exercises such as dance or Pilates. This systematic review was based on a published protocol in PROSPERO (registration number: CRD42022325975).

Bidirectional associations of physical activity, sleep, and self-reported mental health in young adults participating in an online wellness intervention during the COVID-19 pandemic

Purpose

The purpose of this study was to examine the bidirectional associations of physical activity (PA), sleep, and mental health in young adults participating in an online wellness intervention from October 2021 to April 2022.

Methods

Participants were a sample of undergraduate students from one US university (N = 89; 28.0% freshman; 73.0% female). The intervention was a 1-h health coaching session that was delivered either once or twice by peer health coaches on Zoom during COVID-19. The number of coaching sessions was determined by random allocation of participants to experimental groups. Lifestyle and mental health assessments were collected at two separate assessment timepoints after each session. PA was assessed using the International Physical Activity Questionnaire-Short Form. Weekday and weekend sleep were assessed by two one-item questionnaires and mental health was calculated from five items. Cross-lagged panel models (CLPMs) examined the crude bidirectional associations of PA, sleep, and mental health across four-time waves (i.e., T1 through T4). To control for individual unit effects and time-invariant covariates, linear dynamic panel-data estimation using maximum likelihood and structural equation modeling (ML-SEM) was also employed.

Results

ML-SEMs showed that mental health predicted future weekday sleep (β = 0.46, p < 0.001) and weekend sleep predicted future mental health (β = 0.11, p = 0.028). Although CLPMs showed significant associations between T2 PA and T3 mental health (β = 0.27, p = 0.002), no associations were observed when unit effects and time-invariant covariates were accounted for.

Conclusion

Self-reported mental health was a positive predictor of weekday sleep and weekend sleep positively predicted mental health during the online wellness intervention.
