The first post hoc analysis reinforced the observed self-client attitude asymmetry, showing that MHPs associated their own gaming experiences with more positive and fewer negative meanings compared to their clients' gaming. The second post hoc analysis suggested that MHPs expected game-based interventions to be approachable, motivating, and complementary to other treatments, and particularly suited for children and youth, people with strong digital competencies, and clients who were withdrawn.</p><p><strong>Conclusions: </strong>Existing qualitative research on MHPs' perceptions of video games remains limited and has not examined clinicians' broader sense-making of gaming to inform the implementation of game-based interventions. This study identifies how clinician education can build on MHPs' existing perceptions while addressing potential misconceptions by clearly differentiating game-based interventions from enterta","PeriodicalId":14795,"journal":{"name":"JMIR Serious Games","volume":"14 ","pages":"e69236"},"PeriodicalIF":4.1,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13139834/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147814812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While gamification demonstrates the potential for enhancing health behavior, a structured analysis linking to established behavioral frameworks is missing. We provide a viewpoint on whether, as health and life insurers transition from traditional risk assessment toward proactive risk reduction strategies, gamification offers an innovative mechanism to strengthen their prevention initiatives and insurer-insured relationships. We examine how gamification aligns with key theoretical models, including the Behavior Change Wheel and Behavior Change Techniques, and how gamification elements can be mapped onto them. This enables combining multiple Behavior Change Techniques into effective interventions, which provide engaging user experiences and promote intrinsic motivation. We distinguish gamification from mere incentivization, highlighting its potential for sustained health outcomes. We also explore the ethical and practical considerations of gamification in the insurance sector. We highlight the need for a robust ethical framework that preserves an individual's ability to make free and informed decisions, while ensuring inclusivity and absence of discrimination based on personal characteristics that may affect their capacity to engage in healthy behaviors. Similarly, we highlight how privacy, transparency, and accountability need to be prioritized in the governance structure of gamification programs in the sector. Our analysis emphasizes that gamification has the potential to represent the new panacea for the insurance sector, if effective gamified interventions incorporate inclusive design principles, theoretical grounding, ethical accountability, and continuous refinement to ensure alignment with long-term public and individual health objectives. This viewpoint is the first to map gamification and behavioral change frameworks into a unified model for insurer-led health behavior interventions and encourage greater investment in gamified wellness products and the use of theory-driven behavioral science in insurance-led digital health tools.</p>","PeriodicalId":14795,"journal":{"name":"JMIR Serious Games","volume":"14 ","pages":"e80684"},"PeriodicalIF":4.1,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13075540/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147673530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While prior research has explored leadership and communication as isolated factors, the multivariate interactions between behavioral indicators remain poorly understood. A deeper understanding of these relationships can reveal which behavioral and demographic factors most strongly predict successful outcomes, offering insights relevant to both scientific research and practical training design.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective: &lt;/strong&gt;This study aimed to develop machine learning (ML) models to predict team success in SGs. Specifically, it sought to identify the behavioral and demographic predictors that most strongly influence team performance outcomes.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This study used a cross-sectional retrospective design. Behavioral and demographic data were analyzed from 233 teams participating in escape room-based SGs delivered by JGM Serious eXperiences in The Netherlands. Teams of 2-8 players (mean age 25.8 y; 53 all-male, 55 all-female, and 125 mixed-gender) were scored by trained observers across collaboration, communication, and leadership constructs using Likert-scale indicators. Exploratory data analysis compared winning (n=141) and losing teams (n=92) using descriptive statistics, Pearson correlations, and significance testing (independent-samples t tests and Mann-Whitney U tests). Mean differences were interpreted with 95% CIs. A total of 4 ML models: logistic regression, random forest, multilayer perceptron, and support vector classifier, were trained using 5-fold cross-validation (F1-score). The best model was interpreted using SHAP (Shapley Additive Explanations).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Winning teams scored higher on several behavioral constructs, but only 4: knowledge sharing, leadership, guidance, and extraversion, showed statistically significant differences between winners and losing teams. These effects were supported by 95% CIs, Shapiro-Wilk tests for normality, and Mann-Whitney U tests where assumptions were violated, indicating that only a subset of behavioral indicators meaningfully distinguishes successful teams. Among the ML models, logistic regression achieved the highest accuracy (88%), followed by multilayer perceptron (87%), random forest (87%), and support vector classifier (85%). SHAP analysis showed that gender composition and prior escape-room experience were the strongest demographic predictors of success, while \"celebrating progress\" (extern5) and \"taking initiative when the team is stuck\" (sturing5) were the most influential behavioral indicators.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;This work demonstrates the usefulness of multivariate analysis in studying and understanding complex human behavior in SG environments as opposed to studying isolated behavioral indicators, often described in previous studies.
