SGER: DHS and NSF Collaboration: Addendum to NC START National Household Survey

SES-0647736琳达B。Bourque南加州大学国土安全部（DHS）资助了许多位于美国各地的卓越中心。作为国土安全部资助的国家恐怖主义研究和应对恐怖主义联盟（START）的一部分，加州大学洛杉矶分校正在进行一项关于灾害经历和准备的全国家庭调查。最初的国土安全部奖支持制定和管理一项电话调查，通过随机数字拨号选择全国1 500个样本。 这一样本太小，无法对亚组进行估计，无论这些群体是按居住地点还是种族/族裔定义的。 该项目为扩大样本（增加1100名答卷人）提供支持，以获得更好的分组估计数，从而提高进行分组比较的能力。增加的支持将使PI能够充分抽样，以获得两个分层内和跨两个分层的代表性不足群体的更稳定估计数，并加强群体间的比较。 具体来说，这一点以及对其他来源的额外支持将使PI能够将样本增加到3，300个，在三个高能见度城市中的超额样本为1000个，在美国大陆其他地区的样本为2300个。 能见度高的城市包括纽约市（布朗克斯、金斯、纽约、皇后区、史泰登岛）、华盛顿、DC地区（DC、阿灵顿县、费尔法克斯县、威廉王子县、劳登县、蒙哥马利县、乔治王子县）和洛杉矶县。调查将应被调查者的要求，在6个月的时间内使用计算机辅助电话访谈（CATI）以英语或西班牙语完成。 使用随机数字拨号选择家庭，电话号码预先分为两个层次。 调查将收集关于预防、应对、恢复和风险沟通的基线数据，并将公众对恐怖主义和自然灾害的认识和准备情况进行比较。 更广泛地说，研究结果将使未来的研究人员和决策者能够更好地设计恐怖主义和其他备灾信息和相关干预措施。

SES-0647736Linda B. BourqueUniversity of Southern California The Department of Homeland Security (DHS) has funded a number of Centers of Excellence located throughout the United States. As part of the DHS-funded National Consortium for the Study of Terrorism and Responses to Terrorism (START), UCLA is conducting a National Household Survey on Disaster Experiences and Preparedness. The original DHS award supports the development and administration of a telephone survey with a national sample of 1,500 selected by random digit dialing. This sample is too small to make estimates about subgroups, whether these groups are defined by residential location or race/ethnicity. This project provides support to enlarge the sample (increase by 1100 respondents) to obtain better estimates of subgroups and thus enhance the ability to make subgroup comparisons. The increased support will enable the PI to sample sufficiently to obtain more stable estimates of underrepresented groups within and across both strata, and for enhanced inter-group comparisons. Specifically, this and additional support for other sources will allow the PIs to increase the sample to 3,300, with an over-sample of 1000 in the three high visibility cities and a sample of 2300 throughout the rest of the continental US. The high visibility cities is comprised of New York City (Bronx, Kings, New York, Queens, Staten Island), the Washington, DC area (DC, Arlington County, Fairfax County, Prince William County, Loudoun County, Montgomery County, Prince George's County) and Los Angeles County. The survey will be completed using Computer Assisted Telephone Interviewing (CATI) over a 6-month period in English or Spanish at the request of the respondent. Households are selected using random digit dialing, and phone numbers are pre-stratified into two strata. The survey will collect baseline data on prevention, response, recovery and risk communication and will enable the comparison of the public's knowledge and preparation for terrorism with that for natural disasters. More broadly, study findings will allow future researchers and policy makers to better design terrorism and other disaster preparedness messages and associated intervention.
