Abstract
Dietary intake is notoriously difficult to measure in children. Laboratory test meals address some of the methodological concerns of self-report methods, but may also be susceptible to social desirability bias, referring to the tendency for individuals to adjust their behaviors in order to be perceived more positively. The aim of the current study was to evaluate whether social desirability bias was associated with children's energy intake during a laboratory test meal, and whether this association varied by food type (total caloric intake, snack food intake, fruit/vegetable intake) and sex. A total of 82 children (M age = 9.45 ± 0.85; 50 % girls; 84.1 % rural; 85.4 % White) completed several surveys, including the Children's Social Desirability Scale and had their body composition measured. At lunchtime, they were granted access to a multi-array test meal (>5000 kcal). After adjusting for lean mass, fat mass, depressive symptoms, and parental food restriction, children who reported higher social desirability bias consumed fewer calories from snack foods (B = -11.58, p = .009, semi-partial correlation = -0.28). Boys with higher social desirability bias consumed less calories from fruits and vegetables (B = -6.47, p = .010, semi-partial correlation = -0.411); this association was not significant in girls. The desire to be perceived in a positive manner may influence children's eating behaviors in experimental paradigms. Replication studies with larger, more diverse pediatric samples are needed, as are strategies to reduce the effects of social desirability bias on test meal intake in order to enhance the validity of this dietary assessment approach.

Abstract
Scholarly research has consistently shown that teachers present negative assessments of and attitudes toward migrant students. However, previous studies have not clearly addressed the distinction between implicit and explicit prejudices, or identified their underlying sources. This study identifies the explicit and implicit prejudices held by elementary and middle school teachers regarding the learning abilities of an ethnic minority group: Haitian students within the Chilean educational system. We use a list experiment to assess how social desirability and intergroup attitudes toward minority students influence teachers' prejudices. The findings reveal that teachers harbor implicit prejudices towards Haitian students and are truthful in reporting their attitudes, thereby contradicting the desirability bias hypothesis. We suggest that teachers rely on stereotypes associated with the students' nationality when assessing Haitian students' learning abilities. The implications of these results are discussed in relation to theories grounded in stereotypes and intergroup attitudes.

Abstract
Reporting of condom-use can limit researchers' understanding of high-risk sexual behaviours. We compared self-reported condom-use with the Yc-DNA biomarker data and investigated potential factors influencing participation in, and reporting of, sexual behaviours. Self-reported data were collected using Audio Computer Assisted Self Interviews (ACASI) and samples for Yc-DNA biomarker were collected using self-administered and health worker-collected vaginal swabs from 644 women (aged 15-24 years) who were not living with HIV. Yc-DNA results and interview data were compared using McNemar-Bowker Analysis and Cohen's Kappa. Test statistics for Yc-DNA biomarker were calculated. Log Binomial models for Yc-DNA and self-reported results were conducted to assess for association. We found strong evidence (p < 0.001) for a difference between Yc-DNA and self-reported results. 13.7% of participants reported consistent condom-use with all partners, regardless of HIV status. Self-reported condom-use was discordant in 50.0% (n = 206) of cases, when compared to Yc-DNA results. Positive Yc-DNA results were found to be associated with older age (RR 1.36; 95%CI 1.04, 1.76 p = 0.023). Self-reported condom-use with partners with unknown HIV status was associated with higher education (RR 0.76; 95%CI 0.58,0.99 p = 0.043). Sensitivity analysis did not determine difference between methods for controlling for missing data. We found significant under-reporting of condomless sex in the self-reported data when compared to Yc-DNA results.

Abstract
BACKGROUND Prevalence of Non-Medical Use of Prescription Stimulants (NMUPS) is estimated to be high among young adults enrolled in college. However, precise estimation of the prevalence of NMUPS is challenging owing to biases affecting self-report of sensitive and potentially illegal behaviors. OBJECTIVE This study aimed to estimate the prevalence and risk factors of NMUPS using the crosswise randomized response technique (CRRT) and compare findings to the traditionally-used direct self-report (DSR) method. METHODS This study utilized a cross-sectional, randomized experimental design to survey adult undergraduate students at a major southeastern university in the United States. Eligible respondents were randomly assigned to a DSR group or a CRRT group. Those in the DSR group were presented a direct question about NMUPS, but those in the CRRT group were asked to indicate whether their response to the NMUPS question was the 'same' or 'different' compared to a random non-sensitive question. RESULTS Prevalence of NMUPS was found to be 18.6% (95% CI:18.5%-18.7%) in the DSR group and 32.5% (95% CI:32.1%-32.9%; p = 0.003) in the CRRT group. Logistic regression analysis predicting NMUPS in the DSR group showed that it was significantly associated with positive expectancies (OR:3.50; 95% CI:2.44-5.02), negative expectancies (OR:0.49; 95% CI:0.35-0.68), perceived norms (OR:1.71; 95% CI:1.27-2.29), and religious beliefs (OR:0.69; 95% CI:0.52-0.92). CONCLUSIONS The setting and mechanism of the survey is likely closely related to the validity of prevalence estimation of sensitive behaviors. This study found that prevalence of sensitive behaviors such as NMUPS is significantly higher when respondents are provided increased anonymity.

Abstract
PURPOSE To test the efficacy of two interventions to reduce alcohol use and increase viral suppression compared to a control in persons with HIV (PWH). METHODS In a three-arm (1:1:1) randomized controlled trial (N = 269), we compared in-person counselling (45-70 minutes, two sessions over three months) with interim monthly booster phone calls (live call arm) or twice-weekly automated booster sessions (technology arm) to a brief advice control arm. We enrolled PWH self-reporting unhealthy alcohol use (Alcohol Use Disorders Identification Test - Consumption, prior three months, women ≥3, men ≥4). Primary outcomes were number of self-reported drinking days (NDD) in the prior 21 and biomarker phosphatidylethanol (PEth) at six and nine months and viral suppression (<40 copies/mL) at nine months; we adjusted for sex and baseline outcomes. RESULTS At baseline, mean 21-day NDDs were 9.4 (95 % CI: 9.1-9.8), mean PEth was 407.8 ng/mL (95 % CI: 340.7-474.8), and 89.2 % were virally suppressed. At follow-up, there were significant reductions in mean NDDs for the live call versus control arm (3.5, 95 % CI:2.1-4.9, p < 0.001) and for the technology versus control arm (3.6, 95 % CI: 2.2-5.1, p < 0.001). The mean PEth differences compared to the control arm were not significant, i.e. 36.4 ng/mL (95 % CI: -117.5 to 190.3, p = 0.643) for the live call and -30.9 ng/mL (95 % CI: -194.8 to 132.9, p = 0.711) for the technology arm. Nine-month viral suppression compared to the control was similar in the live call and in the technology arm. CONCLUSION Intervention effects were found on self-reported NDD but not PEth or viral suppression, suggesting no treatment effect. (NCT #03928418).

Abstract
Despite the increasing popularity of mixed-mode approaches to data collection, studies examining measurement equivalence across different survey modes in representative samples of the general population, particularly focusing on measures of socially sensitive psychological constructs, are sparse. In this study, we used data from a large representative sample of the Slovenian population (N = 9,900) collected as part of the third wave of the European Health Interview Survey (EHIS) to examine mode-inherent effects (i.e., measurement effects that cannot be neutralized by clever survey design) of the traditional interviewer-mediated face-to-face mode and the increasingly popular self-administered web mode on three measures of psychological functioning, namely the Patient Health Questionnaire Depression Scale (PHQ-8), the Satisfaction with Life Scale (SWLS), and the Mental Health Continuum - Short Form (MHC-SF). After controlling for self-selection propensities, our results showed strict measurement invariance for all three scales across the two survey modes, but statistically significant and notable differences in latent means, suggesting that individuals who respond face-to-face systematically report better psychological functioning than individuals who respond over the web. These results suggest significant mode inherent effects that cannot be attributed to measurement non-invariance of the scales between face-to-face and web survey modes, but most likely to social desirability bias in responses achieved in the presence of an interviewer. Administration mode effects must be considered when interpreting and comparing results obtained through different survey modes, particularly interviewer-mediated versus self-administered modes, especially when using measures of culturally desirable traits and behaviors, such as mental health and well-being.

Abstract
PURPOSE Accurate measures of violence are difficult to obtain from self-reported data because of stigmatization and social undesirability of the topic. Most methods that attempt to reduce such biases require literacy and either remove the benefits of interviewer guidance or do not give individual-level results. We tested a low-tech nonverbal response card that avoids revealing interviewees' responses to interviewers while retaining interviewer support among adolescents in communities with very low educational attainment. METHODS As part of a broader health questionnaire, we asked a sample of 1,644 adolescents, aged 12-20 years, in northwestern Burkina Faso about their experiences of physical and sexual violence. We randomized participants to either a conventional verbal response arm or a nonverbal response card arm where respondents' answers were unspoken and not displayed to interviewers. We first evaluated response validity and reliability in each arm, then compared prevalence rates across arms and evaluated whether any differences varied by respondent characteristics using regression models. RESULTS The level of internal reliability of responses among nonverbal respondents was similar to or greater than that of verbal respondents. Nonverbal respondents reported similar patterns of physical assault and sexual debut as verbal respondents but significantly higher levels of sexual assault and forced sex. These differences were broadly similar across sample subgroups defined by age, gender, proneness to social desirability, and mental health. CONCLUSIONS Nonverbal response cards offer a practical and beneficial method for reducing underreporting of stigmatized and traumatic experiences while maintaining data quality in low-literacy populations.

Abstract
In social research, investigating sensitive, highly personal or embarrassing issues by means of standard survey techniques based on direct questioning leads to refusals to answer or false responses which, generally, flaw the validity of the analyses and produce incorrect inferences. To correct biases induced by nonresponse or underreporting of sensitive matters, Warner (1965) introduced an indirect questioning approach, known as the randomized response technique, which allows researchers to estimate the proportion of individuals with sensitive attributes or behaviors, while ensuring respondents' privacy protection. In this article, we consider the randomized response model proposed by Christofides (2003) and, through a simulation and an empirical study, compare different estimation methods for the prevalence of a sensitive attribute. Specifically, we discuss how the model has been implemented in a pilot study to collect data and derive maximum likelihood and Bayesian estimates for the proportion of non-heterosexuals aged 20 years or older for the Taiwanese population and for some subgroups of it by sex and age. Our analysis, and in particular the Bayesian approach, seems to meet the expectation of social researchers and experts of sexual behaviors. In fact, the produced estimates are higher than official findings in Taiwan obtained by direct questioning in face-to-face interviews and provide a more reliable picture of sexual identity in the country. Moreover, Bayesian estimates appear more accurate than those produced by the method of moment and the maximum likelihood method.

Abstract
Social desirability bias, which is the tendency to under-report socially undesirable health behaviours, significantly distorts information on sensitive behaviours that is gained from self-reports. As a result, self-reported condom use among high-risk populations is thought to be systematically over-reported, and it is impossible to identify the determinants of condom use. The main objective of the article is to elicit unbiased information on condom use among female sex workers (FSWs) using the double list experiment method to analyse the role of HIV infection and exposure to HIV prevention methods in condom use. More specifically, the difference in levels of condom use between HIV-positive and HIV-negative FSWs is estimated. In addition, the role of FSWs' registration and participation in a pre-exposure prophylaxis (PrEP) demonstration project in condom use is considered. A list experiment was designed to elicit condom use information from 786 FSWs in Senegal who were surveyed in 2015 and 2017. Using the list experiment method, participants were randomly assigned to one of two groups (treatment or control) and were asked to report the number of statements they agreed with. Respondents assigned to the control group were presented with three non-sensitive items, whereas those allocated to the treatment group were presented with the same three statements plus the sensitive item (e.g. 'I used a condom during my last intercourse with a client'). Comparing the average number of sentences that were agreed with in both groups provides an estimation of the condom use rate in the treatment group and estimating such prevalence for several sub-groups allows the role of HIV infection risk in condom use to be identified. The percentage of FSWs using condoms in their last sexual intercourse with a client was 80% in 2015 and 78% in 2017, which was significantly lower than the 97% obtained in the face-to-face surveys in both waves. When estimating condom use among sub-groups with the list experiment method, we found that condom use among HIV-positive FSWs was only 34%, which was 47 percentage points lower than condom use among HIV-negative FSWs. We also found that registered FSWs are more likely to use condoms than clandestine FSWs. However, we did not find any difference in condom use between FSWs who were enrolled in the PrEP demonstration project and those who were not enrolled. Health policies should therefore aim to increase condom use among HIV-positive FSWs.

Abstract
RATIONALE Social desirability bias, which is the tendency to under-report socially, undesirable health behaviours, significantly distorts information on sensitive behaviours, gained from self-reports and prevents accurate estimation of the prevalence of those, behaviours. We contribute to a growing body of literature that seeks to assess the performance of the list experiment method to improve estimation of these sensitive health behaviours. METHOD We use a double-list experiment design in which respondents serve as the treatment group for one list and as the control group for the other list to estimate the prevalence of two sensitive health behaviours in different settings: condom use among 500 female sex workers in urban Senegal and physical intimate partner violence among 1700 partnered women in rural Burkina Faso. First, to assess whether the list experiment improves the accuracy of estimations of the prevalence of sensitive behaviours, we compare the prevalence rates estimated from self-reports with those elicited through the list experiment. Second, we test whether the prevalence rates of the sensitive behaviours obtained using the double-list design are similar, and we estimate the reduction in the standard errors obtained with this design. Finally, we compare the results obtained through another indirect elicitation method, the polling vote method. RESULTS We show that the list experiment method reduces misreporting by 17 percentage points for condom use and 16-20 percentage points for intimate partner violence. Exploiting the double-list experiment design, we also demonstrate that the prevalence estimates obtained through the use of the two lists are identical in the full sample and across sub-groups and that the double-list design reduces the standard errors by approximately 40% compared to the standard errors in the simple list design. Finally, we show that the list experiment method leads to a higher estimation of the prevalence of sensitive behaviours than the polling vote method. CONCLUSION The study suggests that list experiments are an effective method to improve estimation of the prevalence of sensitive health behaviours.

Abstract
Social desirability bias has been documented in self-reported diet as well as in voting behavior, but not in regards to sweetened beverage consumption or sweetened beverage taxes. We find evidence that respondents in a mixed-mode opinion survey exhibit social desirability bias in both reported sweetened beverage consumption and beliefs about the health and economic benefits of sweetened beverage taxes. We do so in a study of 1704 adults residing in Seattle, Minneapolis, and the D.C. metro area. Phone respondents in our survey under-report sweetened beverage consumption by 0.63 beverages per week relative to web respondents (average web respondent consumption is 3.55 beverages per week). They also over-report their beliefs about the positive health and economic impacts of sweetened beverage taxes by 0.54 points in an 18-point index (average web respondent index score is 2.79). These differences are measured after we control for selection into survey mode by using matching methods, and we interpret them as occurring due to social desirability bias. In contrast to these findings, there is no modal difference in respondents' stated approval of sweetened beverage taxes, and so we conclude that this question is not subject to social desirability bias.

Abstract
Women tend to under-report or misreport their abortion experiences, mainly because abortion is considered a sensitive issue for cultural, religious, political or other reasons in many countries across the world. Turkey, where induced abortion is an increasingly sensitive issue due to intense statements against induced abortion on religious grounds by influential politicians, and a hidden agenda to prohibit the practice, especially in public health facilities, in recent years, is no exception. This study focused on the increase in level of misreporting of induced abortion in Turkey and its link to social desirability bias using pooled data from 1993 and 2013 Turkish Demographic and Health Surveys. A probabilistic classification model was used to classify women's reported abortions. The findings confirmed that the level of misreporting of induced abortions has increased from 18% to 53% among all terminated pregnancies over the period 1993-2013 in Turkey. This marked increase, especially among women in the lower socioeconomic sections of society, may be largely associated with the prevailing political environment, and increase in social stigmatization against induced abortion in Turkey over recent decades.

Abstract
Novel monitoring technologies in HIV research, such as electronic adherence monitors (EAMs), have changed the nature of researcher-participant interactions. Yet little is known about how EAMs and the resulting interaction between researchers and participants affect research participation and the data gathered. We interviewed participants and research assistants (RAs) in an observational cohort study involving EAMs for HIV antiretroviral therapy (ART) in Uganda. We qualitatively explored interviewees' views about ethical issues surrounding EAMs and assessed data with conventional and directed content analysis. Participants valued their relationships with RAs and were preoccupied with RAs' perceptions of them. Participants were pleased when the EAM revealed regular adherence, and annoyed when it revealed non-adherence that contradicted self-reported pill-taking behavior. For many, the desire to maintain a good impression incentivized adherence. But some sought to creatively conceal non-adherence, or refused to use the EAM to avoid revealing non-adherence to RAs. These findings show that participants' perceptions of the study staff's perceptions of them affected the experience of being monitored, study participation, and ultimately the data gathered in the study. Investigators in monitoring-based research should be aware that social interactions between participants and study staff could affect both the practical and ethical conduct of that research.

Abstract
BACKGROUND List randomization (LR), a survey method intended to mitigate biases related to sensitive true/false questions, has received recent attention from researchers. However, tests of its validity are limited, with no study comparing LR-elicited results with individually known truths. We conducted a test of LR for HIV-related responses in a high HIV prevalence setting in KwaZulu-Natal. By using researcher-known HIV serostatus and HIV test refusal data, we were able to assess how LR and direct questionnaires perform against individual known truth. METHODS Participants were recruited from the participation list from the 2016 round of the Africa Health Research Institute demographic surveillance system, oversampling individuals who were HIV positive. Participants were randomized to two study arms. In Arm A, participants were presented five true/false statements, one of which was the sensitive item, the others non-sensitive. Participants were then asked how many of the five statements they believed were true. In Arm B, participants were asked about each statement individually. LR estimates used data from both arms, while direct estimates were generated from Arm B alone. We compared elicited responses to HIV testing and serostatus data collected through the demographic surveillance system. RESULTS We enrolled 483 participants, 262 (54%) were randomly assigned to Arm A, and 221 (46%) to Arm B. LR estimated 56% (95% CI: 40 to 72%) of the population to be HIV-negative, compared to 47% (95% CI: 39 to 54%) using direct estimates; the population-estimate of the true value was 32% (95% CI: 28 to 36%). LR estimates yielded HIV test refusal percentages of 55% (95% CI: 37 to 73%) compared to 13% (95% CI: 8 to 17%) by direct estimation, and 15% (95% CI: 12 to 18%) based on observed past behavior. CONCLUSIONS In this context, LR performed poorly when compared to known truth, and did not improve estimates over direct questioning methods when comparing with known truth. These results may reflect difficulties in implementation or comprehension of the LR approach, which is inherently complex. Adjustments to delivery procedures may improve LR's usefulness. Further investigation of the cognitive processes of participants in answering LR surveys is warranted.

Abstract
BACKGROUND Social desirability response bias may lead to inaccurate self-reports and erroneous study conclusions. The present study examined the relationship between social desirability response bias and self-reports of mental health, substance use, and social network factors among a community sample of inner-city substance users. METHODS The study was conducted in a sample of 591 opiate and cocaine users in Baltimore, Maryland from 2009 to 2013. Modified items from the Marlowe-Crowne Social Desirability Scale were included in the survey, which was conducted face-to-face and using Audio Computer Self Administering Interview (ACASI) methods. RESULTS There were highly statistically significant differences in levels of social desirability response bias by levels of depressive symptoms, drug use stigma, physical health status, recent opiate and cocaine use, Alcohol Use Disorders Identification Test (AUDIT) scores, and size of social networks. There were no associations between health service utilization measures and social desirability bias. In multiple logistic regression models, even after including the Center for Epidemiologic Studies Depression Scale (CES-D) as a measure of depressive symptomology, social desirability bias was associated with recent drug use and drug user stigma. Social desirability bias was not associated with enrollment in prior research studies. CONCLUSIONS These findings suggest that social desirability bias is associated with key health measures and that the associations are not primarily due to depressive symptoms. Methods are needed to reduce social desirability bias. Such methods may include the wording and prefacing of questions, clearly defining the role of "study participant," and assessing and addressing motivations for socially desirable responses.

Abstract
This paper focuses on the concept of multiple discrimination and its measurement through survey methods. The study was designed as a quasi-experimental comparison of survey mode effects on the quality of discrimination measurement: the traditional 'face-to-face' survey, the conventional self-completed mode and CAWI (finally deleted due to its non-comparability). Consistent with our hypothesis, some support was obtained for the social desirability bias and survey mode effects: 1) self-administration of questionnaires favours the declaration of discriminatory attitudes and personal experiences of discrimination; 2) the effect of privacy is greater in direct indicators of discriminatory attitudes; 3) perceptions and experiences of discrimination are more frequently reported by highly educated respondents. Nevertheless, contrary to our expectations, less educated respondents are also affected by survey mode and continue to be underrepresented in self-completed methods. The current research aims to serve as a basis for further research in this area.

Abstract
Estimates of the prevalence of sensitive attributes obtained through direct questions are prone to being distorted by untruthful responding. Indirect questioning procedures such as the Randomized Response Technique (RRT) aim to control for the influence of social desirability bias. However, even on RRT surveys, some participants may disobey the instructions in an attempt to conceal their true status. In the present study, we experimentally compared the validity of two competing indirect questioning techniques that presumably offer a solution to the problem of nonadherent respondents: the Stochastic Lie Detector and the Crosswise Model. For two sensitive attributes, both techniques met the "more is better" criterion. Their application resulted in higher, and thus presumably more valid, prevalence estimates than a direct question. Only the Crosswise Model, however, adequately estimated the known prevalence of a nonsensitive control attribute.

Abstract
Childhood overweight and obesity is a major public health challenge for policymakers in many countries. As the most common supervisors of children's activities, parents have a potentially important role to play in obesity prevention. However, a precondition for parents to improve their children's diets, encourage them to be more physically active, or take them to see a doctor about their weight is for the parent to first recognize that their child is overweight or obese. This paper examines the extent of parental misclassification of child weight status, and its correlates, focusing on the role of parental education and the parent's own obesity status. We find evidence that, among non-obese parents, those who are better-educated report their child's weight status more accurately, but among obese parents, the better-educated are 45.18% more likely than parents with lower secondary education to give a false negative report of their child's overweight/obesity; this may reflect social desirability bias.

Abstract
Epilepsy is a major health issue in rural areas of developing countries. However, heterogeneity of epilepsy prevalence in different studies precludes assessment of the magnitude of the problem. Using similar protocols, two population-based surveys were conducted 12 years apart (2003 and 2015) in a rural Ecuadorian village (Atahualpa). The only difference was a higher people compliance with interviewers during the second survey. Epilepsy prevalence in the 2003 survey was 13.5 per 1,000 (18/1,332) in villagers aged ≥20 years. This rate increased to 26.8 per 1,000 (41/1,530) in the 2015 survey. Thirty-three persons with epilepsy detected during the second survey lived in the village in 2003; six of them had seizures starting after 2003. Of the remaining 27 cases, 13 (48%) denied their problem during the first survey. Further interview revealed that denial was related to lack of confidence with unacquainted field personnel. Social Desirability Scale-17 scores were lower in those who admitted having epilepsy than in those who denied their condition (p = 0.048). Lack of confidence with interviewers and a social desirability bias account for a sizable proportion of epilepsy denial in the study population, and may explain heterogeneity of epilepsy prevalence reported in studies conducted in poor rural settings.

Abstract
Respondents participating in survey or interview based research often tend to give answers that put themselves in a favorable light, displaying social desirability bias (SDB). Understanding the susceptibility of individuals to underreport their perceived unhealthy holiday behaviors or over report holiday behaviors they perceive as healthy has important implications for health promotion and health policy surrounding the holiday season. This study examines SDB specific to the reporting of holiday food consumption and health-related behaviors. An online survey of 620 U.S. consumers was utilized to collect data in which SDB was accounted for via indirect questioning. The online survey was conducted by Purdue University from November 17-19, 2014. Up to 64% of respondents displayed SDB for the eight holiday health statements studied. Respondents over the age of 45 and without children more frequently displayed social desirability bias. Respondents who displayed SDB with respect to acceptable health related holiday food consumption behaviors may be more susceptible to social pressures surrounding other consumption decision making. Understanding SDB in health and behavior reporting, in particular for the traditionally challenging, in terms of health outcomes, holiday season is critical for health practitioners as they seek to promote healthy behaviors.
