BACKGROUND
Risk perceptions are central to many health behavior theories. However, the relationship between risk perceptions and behavior, muddied by instances of inappropriate assessment and analysis, often looks weak.
METHOD
A meta-analysis of eligible studies assessing the bivariate association between adult vaccination and perceived likelihood, susceptibility, or severity was conducted.
RESULTS
Thirty-four studies met inclusion criteria (N = 15,988). Risk likelihood (pooled r = .26), susceptibility (pooled r = .24), and severity (pooled r = .16) significantly predicted vaccination behavior. The risk perception-behavior relationship was larger for studies that were prospective, had higher quality risk measures, or had unskewed risk or behavior measures.
CONCLUSIONS
The consistent relationships between risk perceptions and behavior, larger than suggested by prior meta-analyses, suggest that risk perceptions are rightly placed as core concepts in theories of health behavior.
背景
风险认知是许多健康行为理论的核心。然而，由于存在不当评估和分析的情况，风险认知与行为之间的关系往往显得薄弱。
方法
对评估成人疫苗接种与感知可能性、易感性或严重性之间双变量关联的合格研究进行荟萃分析。
结果
34项研究符合纳入标准（N = 15988）。风险可能性（合并r = 0.26）、易感性（合并r = 0.24）和严重性（合并r = 0.16）显著预测了疫苗接种行为。对于前瞻性研究、具有更高质量风险测量或风险或行为测量无偏差的研究，风险认知与行为之间的关系更大。
结论
风险认知与行为之间的一致关系比先前的荟萃分析所表明的更大，这表明风险认知在健康行为理论中作为核心概念的定位是正确的。
