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

南加州大学国土安全部(DHS)资助了遍布全美的多个英才中心。作为国土安全部资助的国家恐怖主义研究和应对联盟(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验和准备的全国家庭调查。最初的国土安全部奖支持开发和管理一项电话调查，通过随机数字拨号从全国范围内抽取1500名样本进行调查。这个样本太小，无法对亚群进行估计，无论这些群是按居住地点还是种族/民族来定义的。该项目支持扩大样本(增加1100名受访者)，以获得对分组的更好估计，从而提高分组比较的能力。支助的增加将使PI能够进行充分的抽样，以获得对两个阶层内部和跨阶层代表性不足群体的更稳定的估计，并加强群体间的比较。具体地说，这一点以及对其他来源的额外支持将使采购经理人将样本增加到3300个，其中三个高能见度城市的样本增加到1000个，美国大陆其他地区的样本增加到2300个。能见度高的城市包括纽约市(布朗克斯、国王、纽约、皇后区、斯塔顿岛)、华盛顿特区地区(华盛顿特区、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。应被调查者的要求，将在6个月内用英语或西班牙语使用计算机辅助电话访谈(CATI)完成调查。使用随机数字拨号选择家庭，并将电话号码预先分层为两层。调查将收集关于预防、应对、恢复和风险沟通的基线数据，并将使公众能够将对恐怖主义的知识和准备与对自然灾害的知识和准备进行比较。更广泛地说，研究结果将使未来的研究人员和政策制定者能够更好地设计恐怖主义和其他备灾信息以及相关干预措施。

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.
