RESUMEN
BACKGROUND: Although health promotion scholars and practitioners frequently employ video-based promotion, its effectiveness remains uncertain due to mixed findings. Nuanced details regarding content and design also remain under-explored. METHODS: We conducted a comprehensive search across nine databases to identify relevant empirical research articles. RESULTS: Our systematic review included a total of 54 studies, with 38 studies eligible for meta-analysis. Findings highlight the promising potential of video messaging strategies in promoting health behaviors. CONCLUSIONS: Future research should focus on designing video content that targets detection behaviors within an appropriate length, guided by robust theoretical frameworks to maximize the efficacy of video promotion. More substantial evidence is needed to assess whether video promotion can achieve similar persuasive effectiveness across diverse cultural, political, and economic circumstances. Factors related to the audience (e.g., distinct psychological and personality influences) and message characteristics (e.g., length, credibility) should be further explored to better elucidate the relationship between video-based health promotion and health outcomes. PRACTICE IMPLICATIONS: Health practitioners and organizations should incorporate video-based messages in interventions as supplement or alternative means to educate audiences of positive prevention methods, establish accurate attitude and intentions toward prevention behaviors, and increase their vigilance toward risky behaviors.

OBJECTIVE: Numerous studies examined HPV vaccination promotional strategies. However, an overview of theory use, a synthesis of strategies' effectiveness and an examination of the moderating influence of theory are absent. DATA SOURCE: We retrieved studies from Academic Search Complete, Business Source Complete, PubMed, PsycINFO, Web of Science, CMMC, CINAHL, and MEDLINE. STUDY INCLUSION AND EXCLUSION CRITERIA: 1) peer-reviewed articles written in English, 2) experimental or quasi-experimental, 3) measure HPV vaccination-related outcomes, 4) had to contain a control condition and report statistics necessary for conversion (for meta-analysis only). DATA EXTRACTION: 70 and 30 studies were included for the systematic review and meta-analysis respectively. DATA SYNTHESIS: Four major categories were coded: study information, theory use, type of theory, and outcomes. Two independent coders coded the sample (Cohen's Kappa ranged from .8 to 1). RESULTS: Most of the studies were based in the U.S. (77%, k = 54) with convenient samples (80%, k = 56), targeted toward females (46%, k = 32), and around a quarter did not employ any theories (47%, k = 33). Among theory-driven studies, the most commonly used were Framing (22%, k = 19), Health Belief Model (HBM; 13%, k = 12), and Narrative (7%, k = 6). Among controlled studies, promotional strategies were significantly more effective compared to the control (r+ = .25, p < .001). Strategies guided by the information, motivation, behavioral skills model (IMB) were more effective (r+ = .75, p < .001) than studies guided by framing theory (r+ = -.23, p < .001), HBM (r+ = .01, p < .001), and other theories (r+ = .11, p < .001). CONCLUSION: This review contributes to HPV vaccination promotion literature by offering a comprehensive overview of promotional strategies and practical suggestions for future research and practices.

OBJECTIVES: The World Health Organization recognizes that vaccine hesitancy is a top threat to the public health. To address vaccine hesitancy, much research guided by behavioral theories attempted to examine factors that contribute to vaccination intentions. The current study synthesizes the summary effects of attitude, norms and perceived behavioral control on vaccination intentions. METHODS: We searched five databases with relevant keyword combinations without time constraints. A sample of 5149 participants was included for final analysis. RESULTS: Attitude, norms and perceived behavioral control were significant predictors of vaccination intentions with attitude being the strongest. Type of recipient significantly moderated the PBC-intention relationship, while norm-intention correlations were significantly moderated by type of norm measures. Formative belief elicitation research had no moderating influences. CONCLUSION: Our findings demonstrate clear support for the utility of theory of planned behavior in explaining vaccine hesitancy. Research is needed on how interventions can change these constructs to motivate vaccination.
