背景资料。在以前的文献中，由于这些研究设计完全是横截面性质的，对暴发的心理行为反应的稳定性和时间演变仍然没有明确的定义。采用随机数字拨号的方法，在2003年严重急性呼吸综合征(SARS)暴发期间和暴发后的不同时间，对4481名香港居民进行了6次基于人群的调查。受访者的状态-特质焦虑量表得分(范围为10-40)呈时间趋势下降，从淘大花园疫情爆发高峰期的24.8分下降到疫情爆发后的14.5分。那些认为感染或死于SARS的可能性更高的人的焦虑分数明显更高。女性受访者、30-49岁的人以及只受过小学或更少教育的人容易产生更大的焦虑。焦虑程度与采取个人防护措施之间存在正的剂量-反应梯度。男性受访者、处于极端年龄的人以及教育水平较低的人不太可能从事自我保护行为。症状的出现是更多使用卫生服务的唯一一致的预测因素。随着时间的推移，预测因素和结果之间的关联的大小和方向具有显着的稳定性。我们的发现可以帮助修改未来的公共服务公告，这些公告应该根据心理行为监测智能来定制，以实现预期的行为结果。未来的研究应该探索使用更复杂的技术，包括结构方程建模和博弈论框架，来分析人口心理和行为，并将这些发现与传播动力学建模相结合。
Background. In previous literature, the stability and temporal evolution of psychobehavioral responses to an outbreak remained undefined, because of the exclusively cross- sectional nature of such study designs.Methods. Using random-digit dialing, we sampled 4481 Hong Kong residents in 6 population-based surveys that were conducted at different times during and after the 2003 outbreak of severe acute respiratory syndrome (SARS).Results. Respondents' State-Trait Anxiety Inventory score ( range, 10-40) showed a decreasing temporal trend, from a high mean value of 24.8 during the peak of the Amoy Gardens outbreak to a postepidemic mean baseline value of 14.5. Those who perceived a higher likelihood of contracting or dying of SARS had significantly higher anxiety scores. Female respondents, individuals aged 30-49 years, and individuals with only a primary education or less were predisposed to greater anxiety. There was a positive dose-response gradient between anxiety level and uptake of personal protective measures. Males respondents, individuals at the extremes of age, and individuals with lower educational levels were less likely to engage in self-protective behavior. The presence of symptoms was the only consistent predictor for greater use of health services. There was remarkable stability in the magnitude and the direction of associations between predictors and outcomes over time.Conclusions. Our findings can assist in modifying public service announcements in the future, which should be tailored to psychobehavioral surveillance intelligence to achieve the desired behavioral outcomes. Future research should explore the use of more-sophisticated techniques, including structural equation modeling and gametheoretical frameworks, to analyze population psychology and behavior, and it should integrate such findings with transmission dynamics modeling.
