A Note on a Simple and Practical Randomized Response Framework for Eliciting Sensitive Dichotomous and Quantitative Information

Many issues of interest to social scientists and policy makers are of a sensitive nature in the sense that they are intrusive, stigmatizing, or incriminating to the respondent. This results in refusals to cooperate or evasive cooperation in studies using self-reports. In a seminal article, Warner (1965) proposed to curb this problem by generating an artificial variability in responses to inoculate the individual meaning of answers to sensitive questions. This procedure was further developed and extended and came to be known as the randomized response (RR) technique. Here, the authors propose a unified treatment for eliciting sensitive binary as well as quantitative information with RR based on a model where the inoculating elements are provided for by the randomization device. The procedure is simple and the authors will argue that its implementation in a computer-assisted setting may have superior practical capabilities.computer-assisted survey methods; randomized response; sensitive variables; statistical survey methodology

A validation of a computer-assisted randomized response survey to estimate the prevalence of fraud in social security

Summary. In the Netherlands, there is a research tradition that measures fraud against regulations by interviewing eligible individuals using a survey. In these studies the sensitive questions about fraud are posed by using a randomized response method.The paper describes the results of a Dutch study into the consequences of replacing home interviews by trained interviewers with Internet-delivered interviews in a survey on fraud in the area of disability benefits. Both surveys used computer-assisted self-interviews with randomized response questions. This study has three goals: first to present the research tradition that makes use of randomized response, second to compare the results of home interviews and the Internet survey and finally to introduce an adapted weighted logistic regression method to test the relationship between the probability of fraud and explanatory variables. The results show that there are no systematic differences between modes of interview, either for estimates of the prevalence of fraud or for the identification of associated variables. These outcomes result in the conclusion that the Internet survey is a useful and cost-effective instrument for measuring fraud in a population, and that it is unlikely that replacing home interviews with the Internet survey will result in a significant break with tradition

Late-Onset PTSD in Unaccompanied Refugee Minors: Exploring the Predictive Utility of Depression and Anxiety Symptoms

Following resettlement in Western countries, unaccompanied refugee minors (URM) are at risk of developing posttraumatic stress disorder (PTSD). It is unclear to what extent PTSD in this group may become manifest at later stages following resettlement and which factors are associated with late onset. We examined data from URM collected 1 (T1) and 2 years (T2) following resettlement for differences between groups with no PTSD, PTSD at T1, and late-onset PTSD (at T2 only) using multinomial regression and path analysis. Of the children and adolescents (ages 12-18) completing both assessments (N = 554), 223 (40%) met criteria for PTSD at T1, and 88 (16%) endorsed late-onset PTSD. Late-onset PTSD was associated with traumatic event exposure, older age, and low education. In the late-onset PTSD group, the predictive effects of traumatic event exposure on symptom severity at T2 were fully mediated by depression and anxiety symptoms at T1. These results suggest that late-onset PTSD is a clinically relevant problem among URM that may be heralded by early depression and anxiety symptom
