Effectiveness of respondent driven sampling to recruit undocumented Central American immigrant women in Houston, Texas for an HIV behavioral survey

(Il)legality and psychosocial well-being: Central Asian migrant women in Russia

Legal status has shown far-reaching consequences for international migrants' incorporation trajectories and outcomes in Western contexts. In dialogue with the extant research, we examine the implications of legal status for subjective well-being of Central Asian migrant women in the Russian Federation. Using survey data collected through respondent-driven sampling in two large cities, we compare migrants with regularized and irregular legal statuses on several interrelated yet distinct dimensions of subjective well-being. We find that, regardless of other factors, regularized status has a strong positive association with migrants' perception of their rights and freedoms but not with their feeling of being respected in society. Regularized status is positively associated with self-efficacy and negatively with depression. Yet, no net legal status difference is found in migrants' views on their relations with other migrants or on treatment of migrants by native-borns. The findings are situated within the cross-national scholarship on the ramifications of racialized immigrant (il)legality and its implications for membership and belonging.

Reassessing geographic bottlenecks in a respondent-driven sampling based multicity study in Brazil

This study analyzes the spatial dynamics of drug users' recruitment chains in the context of a respondent-driven sampling (RDS) study in the city of Recife, Brazil. The purpose is to understand the geographic bottlenecks, influenced by social geography, which have been a major challenge for RDS-based studies. Temporo-spatial analysis was used. Sequential maps depicted the dynamics of the recruiting process, considering neighborhood of residence and/or places of drug use. Poisson regression was fitted to model the recruiting rate by neighborhood of residence and/or places of drug use, and the different neighborhoods' demographics. The distance between neighborhood of residence and/or places of drug use and the assessment center was negatively associated with recruitment. There was a positive association between the proportion of the population living in informal settings and the recruiting rate per neighborhood of residence and/or places of drug use. Recruitment chains depend on the social geography and demographics of the population. Studies should incorporate seeds from as many neighborhoods as possible, and more than one assessment center should be utilized.

Modes of administering sexual health and blood-borne virus surveys in migrant populations: A scoping review

There has been a growing number of sexual health and blood-borne virus (SHBBV) surveys specifically administered to migrant populations. The purpose of this scoping review is to collate available information about how SHBBV surveys have been administered in migrant populations and the effect that mode of administration has on data quality, reliability and other practical considerations, e.g. response rates (RR) and social desirability bias. A methodological framework for scoping reviews was applied. SHBBV survey studies administered to international migrants published since 2000 were included if they contained some description of mode of administration. Ninety one studies were identified for inclusion from Embase, Medline, Web of Science, Google Scholar and supplementary grey literature. 'Interview only' was the most common mode of administration (n = 48), predominately comprising face-to-face interviews. Thirty six studies reported data from 'self-completed' surveys only, with pen-and-paper being most common (n = 17). Few studies (n = 7) combined interview and self-completed methods of survey administration. Sixty one studies did not report (or only partially reported) RR or the data necessary to calculate RR. Of the studies that reported RR, most were missing other key information including method of recruitment, consent procedures and whether incentives were offered. Strengths and limitations of all administration modes are summarised. Guidelines to inform future SHBBV survey research in migrant populations are presented.

Health and healthcare in North Korea: a retrospective study among defectors

Background

To gain insights into the socio-economic and political determinants of ill health and access to healthcare in North Korea.

Methods

A retrospective survey using respondent-driven sampling conducted in 2014–15 among 383 North Korean refugees newly resettling in South Korea, asking about experiences of illness and utilization of healthcare while in North Korea, analyzed according to measures of political, economic and human rights indicators.

Results

Although the Public Health Act claims that North Korea provides the comprehensive free care system, respondents reported high levels of unmet need and, among those obtaining care, widespread informal expenditure. Of the respondents, 55.1% (95%CI, 47.7–63.7%) had received healthcare for the most recent illness episode. High informal costs (53.8%, 95%CI, 45.1–60.8%) and a lack of medicines (39.5%, 95%CI, 33.3–47.1%) were reported as major healthcare barriers resulting in extensive self-medication with narcotic analgesics (53.7%, 95%CI, 45.7–61.2%). In multivariate logistic regressions, party membership was associated with better access to healthcare (Adjusted OR (AOR) = 2.34, 95%CI, 1.31–4.18), but household income (AOR = 0.40, 95%CI 0.21–0.78) and informal market activity (AOR = 0.29, 95%CIs 0.15–0.50) with reduced access. Respondents who could not enjoy political and economic rights were substantially more likely to report illness and extremely reduced access to care, even with life-threatening conditions.

Conclusions

There are large disparities in health and access to healthcare in North Korea, associated with political and economic inequalities. The scope to use these findings to bring about change is limited but they can inform international agencies and humanitarian organizations working in this unique setting.

Disconcerting levels of alcohol use among Venezuelan immigrant adolescents in the United States

BACKGROUND

It is estimated that more than 4 million Venezuelans have left their country as a direct result of their nation's widespread social and economic challenges. Although recent research identifies Venezuela as one of the nations with the highest rates of harmful alcohol consumption in the Americas, no research has been conducted on alcohol use among Venezuelan youth in diaspora.

METHODS

Data was collected between November 2018 and June 2019 from 373 Venezuelan immigrant youth ages 12-17 in the United States. The prevalence of past-month and lifetime alcohol use among Venezuelan youth is compared to that of other Hispanic and immigrant youth from the National Survey on Drug Use and Health (NSDUH), and the Construyendo Oportunidades Para Adolecentes Latinos (COPAL) study using independent sample t tests.

RESULTS

The prevalence of past-month and lifetime alcohol use was significantly higher among Venezuelan immigrant youth (15% and 52%, respectively) compared to other Hispanic (9% and 28%) and immigrant (4.5% and 28%) youth in the NSDUH, and youth ages 14-17 in the COPAL study (4.0% and 22%). Among Venezuelan youth reporting alcohol use initiation, 1.5% of youth ages 12-14 and 19% ages 15-17 report lifetime alcohol intoxication.

DISCUSSION

Although preliminary, results indicate that a disconcerting proportion of Venezuelan crisis migrant youth in the US report lifetime alcohol initiation and past-month use. These findings suggest the importance of future research to examine the prevalence and correlates of alcohol use in this population using recruitment and sampling methods that will allow for population-level estimates.

Implementing Respondent-Driven Sampling to Recruit Women Who Exchange Sex in New York City: Factors Associated with Recruitment and Lessons Learned

Respondent-driven sampling (RDS) relies on productive peer recruitment to capture hidden populations. Domestic studies have identified characteristics of productive recruitment among RDS samples of men who have sex with men and persons who use drugs, but not of women who exchange sex, a group vulnerable to HIV infection. We examined sociodemographic-, behavioral-, exchange-sex-, and protocol-related factors associated with recruitment among seeds (n = 25) and peers (n = 297) in the 2016 New York City National HIV Behavioral Surveillance Study cycle focused on women who exchange sex. Recruiter productivity was significantly associated with not having been recently incarcerated, lower rate of HIV testing, and larger exchange sex networks among seeds, and with HIV-prevention services usage among peers. We describe challenges and lessons learned from implementing RDS in this population. Our study identifies seed characteristics and protocol improvements researchers can utilize when implementing future RDS studies among women who exchange sex.

Longitudinal associations between marianismo beliefs and acculturative stress among Latina immigrants during initial years in the United States

Acculturative stress is commonly experienced among Latinx immigrants in the United States who may feel pressured to maintain their heritage cultural norms and beliefs and/or adopt norms and beliefs of the dominant culture. The present study examined longitudinal relations between acculturative stress and endorsement of traditional Latina gender role beliefs (i.e., marianismo). We determined strength of the relations and temporal precedence of acculturative stress and endorsement of marianismo across 3 time points during participants' initial 3 years in the United States using a random intercept cross-lagged panel model. Participants were 530 Latina young adult women (ages 18-23) recruited from Miami-Dade County, Florida. Results suggested that acculturative stress levels at Time 1 positively predicted endorsement of the Family Pillar belief at Time 2, but acculturative stress levels at Time 2 negatively predicted the Virtuous and Chaste and Subordinate to Others beliefs at Time 3. In terms of marianismo beliefs predicting acculturative stress levels over time, the Virtuous and Chaste belief at Time 1 positively predicted acculturative stress at Time 2, and the Silencing Self to Maintain Harmony belief at Time 2 positively predicted acculturative stress at Time 3. Findings suggest that the Family Pillar belief, or feeling responsibility for the family's unity, may be protective against acculturative stress over time. Endorsing certain gender role beliefs (i.e., Virtuous and Chaste, Subordinate to Others) may lead to greater acculturative stress, and Latina young adult women experiencing acculturative stress may alter their endorsement of marianismo beliefs in an attempt to resolve culturally conflicting stress experienced after immigration.

Respondent-Driven Sampling to Recruit Latinos in a Midwest Micropolitan Area: Lessons Learned and Recommendations for Translational Work

Introduction

Latinos constitute a hard-to-reach minority population in Iowa.

Methods

We used respondent-driven sampling (RDS) to supplement random digit dialing (RDD) to recruit Latinos for a community physical activity intervention.

Results

RDS yielded a 59% increase in Latino participation in just two months, with few demographic differences between RDS and RDD groups.

Conclusions

RDS may increase recruitment of underrepresented populations and strengthen community engagement; however, it is not a quick fix for underperforming recruitment methods.

Feasibility of using respondent-driven sampling to recruit participants in superdiverse neighbourhoods for a general health survey

OBJECTIVES

Respondent-driven sampling (RDS), a modified chain-referral system, has been proposed as a strategy for reaching 'hidden' populations. We applied RDS to assess its feasibility to recruit 'hard-to-reach' populations such as migrants and the unemployed in a general health survey and compared it to register-based sampling (RBS).

METHODS

RDS was applied parallel to standard population RBS in two superdiverse neighbourhoods in Bremen, Germany. Prevalences of sample characteristics of interest were estimated in RDS Analyst using the successive sampling estimator. These were then compared between the samples.

RESULTS

Only 115 persons were recruited via RDS compared to 779 via RBS. The prevalence of (1) migrant background, (2) unemployment and (3) poverty risk was significantly higher in the RDS than in the RBS sample. The respective estimates were (1) 51.6 versus 32.5% (95% CI_RDS 40.4-62.7), (2) 18.1 versus 7.5% (95% CI_RDS 8.4-27.9) and (3) 55.0 versus 30.4% (95% CI_RDS 41.3-68.7).

CONCLUSIONS

Although recruitment was difficult and the number of participants was small, RDS proved to be a feasible method for reaching migrants and other disadvantaged persons in our study.

Human Rights as Political Determinants of Health: A Retrospective Study of North Korean Refugees

INTRODUCTION

The gravity, scale, and nature of human rights violations are severe in North Korea. Little is known about the mental health consequences of the lifelong exposures to these violations.

METHODS

In 2014-2015, a retrospective study was conducted among 383 North Korean refugees in South Korea using respondent-driven sampling to access this hidden population. This study collected information on the full range of political and economic rights violations and measured post-traumatic stress disorder, anxiety and depression symptoms, and social functioning by standard instruments. Multivariate regression analysis was performed with the adjustment of political, economic, and demographic variables in 2016-2017.

RESULTS

The results indicate elevated symptoms of anxiety (60.1%, 95% CI=54.3%, 65.7%), depression (56.3%, 95% CI=50.8%, 61.9%), and post-traumatic stress disorder (22.8%, 95% CI=18.6%, 27.4%), which are significantly associated with exposures to political rights violations (ten to 19 items versus non-exposure: anxiety AOR=16.78, p<0.001, depression AOR=12.52, p<0.001, post-traumatic stress disorder AOR=16.71, p<0.05), and economic rights violations (seven to 13 items versus non-exposure: anxiety AOR=5.68, p<0.001, depression AOR=4.23, p<0.01, post-traumatic stress disorder AOR=5.85, p<0.05). The mean score of social functioning was also lower in those who were exposed to political (adjusted difference= -13.29, p<0.001) and economic rights violations (adjusted difference= -11.20, p<0.001).

CONCLUSIONS

This study highlights mental health consequences of lifelong human rights violations in North Korea. Beyond the conventional approach, it suggests the need for a collaborative preventive response from global health and human rights activists to address human rights in regard to mental health determinants of the 20 million people in North Korea.

Economic Incorporation, Civil Inclusion, and Social Ties: Plans to Return Home among Central Asian Migrant Women in Moscow, Russia

This study uses data from a survey of female labor migrants from three Central Asian countries – Kyrgyzstan, Tajikistan, and Uzbekistan – in Moscow, Russia, to examine factors that influence these women's plans to return to their home countries. The conceptual framework considers three types of factors of migrants’ attachment to the host society – economic incorporation, civil inclusion, and social connectedness – while also accounting for migrants’ ties to their homelands. The results of multivariate analyses point to the importance of sector and type of employment, income, legal status, experience of ethnically motivated harassment, and social ties to adults relatives and friends in the host society in shaping return plans. In contrast, connections in the home country do not appear to influence the likelihood of having plans to return. These findings are contextualized within the political, socioeconomic, and ethnocultural reality of the post-Soviet world and related to the cross-national scholarship on return migration.

Respondent driven sampling in a biomonitoring study of refugees from Burma in Buffalo, New York who eat Great Lakes fish

BACKGROUND

Refugees from Burma who consume fish caught from local waterbodies have increased risk of exposure to environmental contaminants. We used respondent driven sampling (RDS) to sample this hard-to-reach population for the first Biomonitoring of Great Lakes Populations program. In the current study, we examined the interview data and assessed the effectiveness of RDS to sample the unique population.

METHODS

In 2013, we used RDS to sample 205 Burmese refugees and immigrants residing in Buffalo, New York who consumed fish caught from Great Lakes waters. RDS-adjusted population estimates of sociodemographic characteristics, residential history, fish consumption related behaviors, and awareness of fish advisories were obtained. We also examined sample homophily and equilibrium to assess how well the RDS assumptions were met in the study.

RESULTS

Our sample was diverse with respect to sex, age, years residing in Buffalo, years lived in a refugee camp, education, employment, and fish consumption behaviors, and each of these variables reached equilibrium by the end of recruitment. Burmese refugees in Buffalo consumed Great Lakes fish throughout the year; a majority of them consumed the fish more than two times per week during summer, and about one third ate local fish more than once per week in winter. An estimated 60% of Burmese refugees in Buffalo had heard about local fish advisories.

CONCLUSIONS

RDS has the potential to be an effective methodology for sampling refugees and immigrants in conducting biomonitoring and environmental exposure assessment. Due to high fish consumption and limited awareness and knowledge of fish advisories, some refugee and immigrant populations are more susceptible to environmental contaminants. Increased awareness on local fish advisories is needed among these populations.

A Social Ecological Study of Psychological Distress among Recently Immigrated, Latina Young Adults

The present study examined potential individual-, cultural-, and interpersonal-level determinants of psychological distress among young adult Latina immigrants during their initial months in the United States (US). Five hundred thirty participants (aged 18-23 years old) immigrated an average of one year before assessment. Higher levels of psychological distress (as measured by the Brief Symptom Inventory, Derogatis & Fitzpatrick, 2004) were associated with undocumented immigration status, more immersion in the dominant (US) society, and more acculturative stress. Participants who more strongly endorsed certain marianismo beliefs [i.e., Latina women should be (a) the spiritual leaders of their family and are responsible for the family's spiritual growth and (b) virtuous and chaste] indicated less distress. Participants who endorsed the belief that Latina women should be subordinate and self-silencing to maintain harmony in relationships reported more intense distress. Women who endorsed the belief that Latinas should be the main source of strength for their family also reported more distress. Participants' attachment to their social network served as a moderator of several direct effects. Participants who experienced close attachment to their social network and more ethnic immersion reported substantively less distress than other participants did. Participants reporting lower attachment and lower endorsement of the virtuous and chaste belief experienced more distress than their peers did. Participants indicating lower attachment and higher endorsement of subordinate and self-silencing beliefs also reported more distress than peers did. Finally, participants who spent less time in the US and reported lower attachment indicated higher levels of distress. Findings inform interventions to eliminate mental health disparities affecting Latina young adults.

Mixed-Status Immigrant Families in the United States: The Role of Social Justice in Intervention Research

More than 4 million unauthorized parents of legal status children currently reside in the United States (Capps, Fix, & Zong, 2016). Developmental scientists and intervention researchers hoping to work with these mixed-status families face a myriad of challenges, largely generated from the population's policy-driven social exclusion. Despite the challenges, there is a moral imperative to work with and support parents and children currently living in mixed-status households. This chapter applies a social justice perspective, largely stemming from Prilleltensky's critical community psychological framework, to improve the relevance and usefulness of research on mixed-status families (Prilleltensky & Nelson, 1997). We discuss the utility of this social justice perspective in theory building, study design and implementation, and dissemination of findings regarding mixed-status families, with exemplars from recent research.

Experiences and Lessons Learned in Using Community-Based Participatory Research to Recruit Asian American Immigrant Research Participants

PURPOSE

By 2050, the number of international migrants is expected to double from 214 million people. Of these, Asian immigrants are projected to comprise the largest foreign-born population in the United States by the year 2065. Asian American immigrants experience numerous health disparities, but remain under-represented in health research. The purpose of this article is to examine the experiences and lessons learned in applying community-based participatory research (CBPR) principles to access and recruit a sample of Asian American research participants.

APPROACH

This article reviews unique barriers to research participation among Asian Americans, describes the principles of CBPR, and provides examples of how these principles were employed to bridge recruitment challenges within a qualitative study.

FINDINGS AND CONCLUSIONS

CBPR facilitated greater research participation among a group of immigrant Asian Americans. Researchers must be additionally mindful of the importance of building trusting relationships with their community partners, understanding the significance of shared experiences, considering fears around immigration status, and considering ongoing challenges in identifying and reaching hidden populations.

CLINICAL RELEVANCE

Clinicians and researchers can employ CBPR principles to guide their work with Asian immigrant communities and other under-represented groups to facilitate access to the population, improve participant recruitment, and foster engagement and collaboration.

Respondent driven sampling is an effective method for engaging methamphetamine users in HIV prevention research in South Africa

BACKGROUND

South Africa, in the midst of the world's largest HIV epidemic, has a growing methamphetamine problem. Respondent driven sampling (RDS) is a useful tool for recruiting hard-to-reach populations in HIV prevention research, but its use with methamphetamine smokers in South Africa has not been described. This study examined the effectiveness of RDS as a method for engaging methamphetamine users in a Cape Town township into HIV behavioral research.

METHODS

Standard RDS procedures were used to recruit active methamphetamine smokers from a racially diverse peri-urban township in Cape Town. Effectiveness of RDS was determined by examining social network characteristics (network size, homophily, and equilibrium) of recruited participants.

RESULTS

Beginning with eight seeds, 345 methamphetamine users were enrolled over 6 months, with a coupon return rate of 67%. The sample included 197 men and 148 women who were racially diverse (73% Coloured, 27% Black African) and had a mean age of 28.8 years (SD=7.2). Social networks were adequate (mean network size >5) and mainly comprised of close social ties. Equilibrium on race was reached after 11 waves of recruitment, and after ≤3 waves for all other variables of interest. There was little to moderate preference for either in- or out-group recruiting in all subgroups.

CONCLUSIONS

Results suggest that RDS is an effective method for engaging methamphetamine users into HIV prevention research in South Africa. Additionally, RDS may be a useful strategy for seeking high-risk methamphetamine users for HIV testing and linkage to HIV care in this and other low resource settings.

Substance abuse treatment utilization, HIV risk behaviors, and recruitment among suburban injection drug users in Long Island, New York

Prevention and treatment of injection drug use remains a public health concern. We used data from the 2005 Centers for Disease Control and prevention National HIV Behavioral Surveillance system to assess substance abuse treatment utilization, risk behaviors, and recruitment processes in a respondent driven sample of suburban injectors. Twelve service utilization and injection risk variables were analyzed using latent class analysis. Three latent classes were identified: low use, low risk; low use, high risk; and high use, moderate/high risk. In multivariate analysis, annual income <$15,000 (adjusted odds ratio (aOR) = 8.19 [95 % confidence interval (CI), 3.83-17.51]) and self-reported hepatitis C virus infection (aOR = 4.32, 95 % CI (1.84-10.17)) were significantly associated with class membership. Homophily, a measure of preferential recruitment showed that injectors with recent treatment utilization appear a more cohesive group than out-of-treatment injectors. Preferentially reaching injection drug users with high risk behaviors and no recent drug treatment history via respondent driven sampling will require future research.

Feasibility of recruiting a diverse sample of men who have sex with men: observation from Nanjing, China

BACKGROUND

Respondent-driven-sampling (RDS) has well been recognized as a method for sampling from most hard-to-reach populations like commercial sex workers, drug users and men who have sex with men. However the feasibility of this sampling strategy in terms of recruiting a diverse spectrum of these hidden populations has not been understood well yet in developing countries.

METHODS

In a cross sectional study in Nanjing city of Jiangsu province of China, 430 MSM were recruited including 9 seeds in 14 weeks of study period using RDS. Information regarding socio-demographic characteristics and sexual risk behavior were collected and testing was done for HIV and syphilis. Duration, completion, participant characteristics and the equilibrium of key factors were used for assessing feasibility of RDS. Homophily of key variables, socio-demographic distribution and social network size were used as the indicators of diversity.

RESULTS

In the study sample, adjusted HIV and syphilis prevalence were 6.6% and 14.6% respectively. Majority (96.3%) of the participants were recruited by members of their own social network. Although there was a tendency for recruitment within the same self-identified group (homosexuals recruited 60.0% homosexuals), considerable cross-group recruitment (bisexuals recruited 52.3% homosexuals) was also seen. Homophily of the self-identified sexual orientations was 0.111 for homosexuals. Upon completion of the recruitment process, participant characteristics and the equilibrium of key factors indicated that RDS was feasible for sampling MSM in Nanjing. Participants recruited by RDS were found to be diverse after assessing the homophily of key variables in successive waves of recruitment, the proportion of characteristics after reaching equilibrium and the social network size. The observed design effects were nearly the same or even better than the theoretical design effect of 2.

CONCLUSION

RDS was found to be an efficient and feasible sampling method for recruiting a diverse sample of MSM in a reasonable time.
