Informing Human Trafficking Clinical Care Through Two Systematic Reviews on Sexual Assault and Intimate Partner Violence

Do Social Service Interventions for Human Trafficking Survivors Work? A Systematic Review and Meta-Analysis

Human trafficking leaves victims with long-term social, psychological, and health effects. Research in this area is still nascent, and there are limited studies that show the effectiveness of existing services for survivors. This study fills the gaps in knowledge of the effectiveness of existing programs through a comprehensive systematic review and meta-analysis. Inclusion and exclusion criteria retained 15 studies using the preferred reporting items for systematic reviews and meta-analyses method, containing 16 populations. Included studies examined programs and/or interventions providing direct services to human trafficking survivors using quantitative pre- and post-intervention measurements published from January 2010 to June 2022. Outcomes among survivors were grouped into five categories: (a) mental health, (b) physical health, (c) social support or social behavior, (d) personal development, and (e) other. Roughly half (n = 31, 51.66%) of the outcomes across the 15 studies were statistically significant. Most measured constructs showed a moderate effect size (E.S.; n = 31, 51.67%). In all, 21 constructs (27.91%) met high E.S. levels, and eight (13.33%) met the criteria for a low-level effect. Analyzing different intervention types, physical-based interventions represented the smallest subset and the largest mean effect size (n = 5, g = 1.632, 95% CI [0.608, 2.655]) followed by standardized therapy (n = 23, g = 1.111, 95% CI [0.624, 1.599]), wrap-around services (n = 14, g = 0.594, 95% CI [0.241, 0.947]), and peer and support group modalities (n = 18, g = 0.440, 95% CI [0.310, 0.571]). A meta-regression showed that non-U.S.-based interventions were significantly more effective than U.S.-based interventions (z = -2.25, p = 0.025). While only 15 studies contributed to this analysis, the current study ushered in new avenues regarding future research, policies, and practice in services for survivors of human trafficking.

Identifying victims of labor trafficking

ABSTRACT

Globally, more than 40 million people are victims of human trafficking, exploited as a black-market commodity generating more than $150 billion annually. These people are forced to work in various industries, including domestic work and escort services. Though studies are limited, survivor interviews have indicated that most trafficked persons presented to a healthcare provider at some point during their captivity. No single validated tool exists for screening all victims of human trafficking across all healthcare settings, but several mechanisms are available for immediate implementation, and all have the potential to pierce the veil and spare a life from further abuse.

Methods Used to Control the Reproductive Choices of Women Who Are Sex Trafficked: Considerations for Health Care Providers

Reproductive control or reproductive coercion has negative health consequences but has not been systematically studied within the context of sex trafficking. Our goal is to identify the range of methods used by sex traffickers and buyers to control the reproductive choices of trafficked women and to provide specific examples of these methods. We searched PubMed, Embase, and PsycInfo using the terms "reproductive control" or "reproductive coercion" and "human trafficking" or "sex trafficking," including papers that contained original, specific examples of reproductive control occurring within the context of sex trafficking. These reports were described and categorized into established domains of reproductive control. Eight articles were located that met our inclusion criteria, of which 6 described outcomes of birth control sabotage, 2 described pressuring into pregnancy, 5 described controlling the outcome of a pregnancy, and 2 described forced birth control or sterilization. Our findings have implications for how to take sexual histories and for identifying and assisting trafficked persons.

Group Therapy for Survivors of Adult Sexual Assault: A Scoping Review

Across the world, women experience significant rates of sexual assault and there is a need to strengthen support services offered to survivors. Group therapy could provide an important addition to services that support healing and growth; however, the effectiveness of group therapy interventions with survivors of adult sexual assault is not well understood and clearer insights into designing and running group therapy interventions require further exploration. This review synthesizes literature exploring group therapy for survivors of adult sexual assault to inform future interventions and research implementing group therapy. A systematic approach was used to gather literature describing and evaluating group therapy interventions with survivors of adult sexual assault. Of the initial 466 articles identified through a comprehensive search strategy including database and hand searches, 32 met the inclusion criteria by describing a group therapy intervention conducted with survivors of adult sexual assault. A thematic approach to analysis was conducted to synthesize and collate the literature. Findings explore potentially useful strategies and characteristics of group therapy with survivors of adult sexual assault and make recommendations for the design and evaluation of future interventions. Group therapy has potential as a valuable support service provided to survivors but further rigorous research and evaluations are required to better capture outcomes and understand how to design and implement effective interventions.

Maternal Health Concerns for Pregnant Labor-Trafficked People: A Scoping Review

We set out to map the (1) living/occupational hazards, (2) health outcomes, and (3) barriers to care that exist for pregnant labor-trafficked people. Eight databases were systematically searched based on inclusion criteria. Five papers were eligible for inclusion. Data on study characteristics, social determinants, hazardous exposures, health outcomes, and barriers to care were extracted and synthesized. Common risk factors and occupational/living hazards were identified. Both were thematically connected with barriers to care and a host of adverse health outcomes. More importantly, a significant gap was discovered with no disaggregated quantitative data on the experience of pregnancy among labor-trafficked people. The interaction of risk factors, occupational/living hazards, and barriers to care experienced by pregnant labor-trafficked people may influence their susceptibility to adverse health outcomes. We need population-based studies, informed by those with lived experience of labor trafficking to examine the experience of pregnancy for labor-trafficked people to improve intervention and support efforts for this population.

"When Her Visa Expired, the Family Refused to Renew It," Intersections of Human Trafficking and Domestic Violence: Qualitative Document Analysis of Case Examples from a Major Midwest City

This study aimed to further understand typologies of trafficking that occur in the home, by an individual's intimate partner (IP) or family members and this overlap with extant knowledge on perpetrator manipulation via the Power and Control Wheel. Inductive and deductive techniques were used to analyze secondary data from a federally funded anti-trafficking program in a Midwest metropolitan area recorded between 2008 and 2017. Cases were included if there was indication of sex or labor exploitation initiated by an IP, family member, or other in the domestic setting via elements of abuse; 59 cases of 213 met this criteria. Most cases included the IP as the trafficker, followed by family members, then others in the domestic setting. Abuse was more commonly used than the threat of abuse. From the Power and Control Wheel, the most frequent types of abuse were using privilege, physical abuse, economic abuse, isolation, and sexual abuse. Case typologies included: those with elements of sex trafficking, specifically forced commercial sex by an IP or family member; those with elements of labor trafficking such as domestic servitude (with or without childcare provision abuse), exploitation in a family business by an IP or family member, or work environments by family and non-family; those with elements of sex and labor trafficking included servile partnerships and forced marriage. Trafficking exploitation by an IP, family member, or in the domestic setting is not uncommon. Intimate relationships with a trafficker, psychological coercion, and threats may reduce reporting of abuse, subsequent provision of services, and result in misclassification as victims of IP violence. This study sheds light on various typologies of trafficking and exploitation in the domestic setting, further expanding the anti-trafficking movement's evidence base for intervention and prevention and adding complexity and nuance to the pathways to trafficking exploitation.

"Because the resources aren't there, then we fail. We fail as a society": A Qualitative Analysis of Human Trafficking Provider Perceptions of Child Welfare Involvement among Trafficked Mothers

BACKGROUND

Little is understood about child welfare involvement (CWI) in cases where the birth mother has experienced human trafficking.

OBJECTIVES

The aim of this study was to explore provider perceptions of the impact of CWI for the trafficked mother.

METHODS

Participants were selected among providers caring for trafficked birth mothers. Semi-structured interviews were conducted with providers and qualitative content analysis was conducted.

RESULTS

Interviewees reported reasons for CWI, positive and negative impacts of CWI and provided recommendations for systems improvement.

CONCLUSION FOR PRACTICE

Recommendations from this exploratory study include mechanisms to support trafficked mothers, train hospital social workers, and systems change. During the prenatal period, strategies to support the trafficked mother may include addressing gaps in social determinants of health, ensuring appropriate medical and mental health care, early screening and referral to substance use treatment services, enhancing community support, and working to develop safety plans for survivors and their families. Enhanced engagement of social workers and all providers to improve understanding of the unique complexity of trafficked mothers is needed. Education should include an understanding that judgement of a caretaker's ability to parent should be current and holistic and not reflexive based on history in the electronic medical record. An exploration of the child welfare system itself should also be undertaken to identify and modify discriminatory laws and policies. Finally, efforts to address social determinants of health in the community and enhance the trauma-informed nature of child welfare referrals could improve the lives of trafficked mothers.

Interventions to support the mental health of survivors of modern slavery and human trafficking: A systematic review

BACKGROUND

Modern slavery is a term which incorporates a range of exploitative situations that involve the violation of human rights and the subjugation of individuals. It presents a significant public health concern. Post-release, survivors of modern slavery have complex mental health needs. Whilst mental health provision is a component of international and national policy, the delivery of evidence-based support remains a gap in the global anti-slavery response.

AIM

To identify and synthesise the evidence base for mental health interventions developed and evaluated for use in a post-slavery survivor population.

METHODS

A systematic literature review was undertaken. The review protocol was prospectively registered with PROSPERO and followed the PRISMA guidance in its reporting. A multi-stage search strategy was utilised to retrieve studies. Quality appraisal was undertaken using the QualSyst tool. Due to heterogeneity in study design, a narrative approach to synthesising the findings was undertaken.

RESULTS

Nine studies met the final inclusion criteria. The narrative synthesis clustered the studies in three themes: study design and population; type of intervention; and outcomes reported. The included studies focussed on specific subpopulations, namely child soldiering, child labour or sex trafficking.

CONCLUSION

This review has highlighted not only important theory-practice gaps in relation to the provision of evidence-based mental health support but scant evidence limited to specific sub-groups (child soldiering, child labour or sex trafficking). The emphasis placed on PTSD within the interventions tested risks mental health support becoming exclusionary to those with other needs. When assessing intervention efficacy, the complex socio-political context in which survivors exist as well as the increasing emphasis on holistic care, personal recovery and lived experience need to be considered. Taking this into account, the case can be made for the inclusion of a wider range of non-clinical outcomes in the assessment of mental health intervention effectiveness.

Study protocol for an evaluability assessment of an anti-human trafficking program

Background

Human trafficking is a serious global challenge associated with a complex array of health inequities for individuals, families, and communities. Consequently, in addition to a conventional criminal justice approach, anti-trafficking scholars have increasingly called for a public health approach to address this global challenge. Such calls have emphasized that a comprehensive, robust, and social justice-informed public health strategy for anti-trafficking must include services to facilitate survivors’ HT exit and recovery, and to prevent their re-victimization. Fortunately, many community-based organizations and non-governmental organizations worldwide have heeded these calls and developed anti-trafficking programs for survivors. Unfortunately, despite the growing numbers of organizations providing anti-trafficking services, research concerning these programs’ effectiveness remains nascent overall, and even more scant when filtered through an equity focus.

Methods

To advance the field by developing guidance concerning how best to evaluate anti-human trafficking programs, an ongoing research project aims to conduct a mixed methods evaluability assessment of a prominent anti-trafficking program using a social justice framework. Guided by well-established evaluability assessment frameworks, the study activities include four sequential steps: (a) focusing the assessment, (b) developing the program theory and logic, (c) gathering feedback, and (d) applying the assessment findings. Activities will include qualitative interviews and focus groups, observations, and quantitative analysis of program data among others. Human subjects and ethical review for the evaluability assessment has been granted by the Office of Human Subjects Research at The University of North Carolina at Chapel Hill.

Discussion

Once completed, evaluability assessment results will provide evidence and products that have the potential to guide both evaluation research and service provision not only for the specific organization under study, but also for other anti-human trafficking programs worldwide. Findings will be developed into a variety of dissemination products tailored for both practice professionals and researchers. In the interim, this protocol manuscript offers research strategies and recommendations that can help inform the development of other studies in the developing field of anti-trafficking program evaluation research.

Analysis of Effectiveness of Individual and Group Trauma-Focused Interventions for Female Victims of Intimate Partner Violence

Group psychological programs for intimate partner violence (IPV) survivors would seem particularly useful since they contribute to interrupting women’s isolation and have cost-effectiveness advantage. This study aims to analyze whether the effectiveness of group interventions for female survivors of IPV is equivalent to that of the individual format. A cognitive-behavioral trauma-focused intervention program was applied in eight weekly sessions in Madrid (Spain) to IPV female survivors with significant posttraumatic symptoms that were randomly assigned to the individual (n = 25) or group (n = 28) intervention format. Measures of posttraumatic stress (Severity of Posttraumatic Stress Disorder Symptoms Scale), depression (Beck Depression Inventory), anxiety (Beck Anxiety Inventory), self-esteem (Rosenberg’s Scale) and social support were analyzed at pre-treatment, post-treatment, and 1-, 3-, 6- and 12-months follow-ups. A total of 28.3% of women dropped out, without significant format differences. Intervention (both formats) had significant improvements with large effect sizes in posttraumatic stress (η²_p = 0.56), depression (η²_p = 0.45), anxiety (η²_p = 0.41) and self-esteem (η²_p = 0.26) that maintained in follow-ups (p < 0.001), without significant differences between formats. Both intervention formats had different evolutions for depression and anxiety (p < 0.05), with better effects in the individual format at the first post-test measurements, but the differences tended to disappear over time. Intervention was effective in improving social support, with no significant differences between formats. All in all, both formats showed similar effectiveness. The group format could be an alternative when applying psychological interventions for female IPV survivors, since it would maintain good cost-effectiveness balance, mainly in the long-term.

Interventions for reducing violence against children in low- and middle-income countries: An evidence and gap map

BACKGROUND

More than half of the children in the world experience some form of interpersonal violence every year. As compared with high-income countries, policy responses in low- and middle-income countries (LMICs) are limited due to resource constraints and paucity of evidence for effective interventions to reduce violence against children in their own contexts, amongst other factors.

OBJECTIVES

The aim of this evidence and gap map (EGM) is to provide an overview of the existing evidence available and to identify gaps in the evidence base on the effectiveness of interventions to reduce violence against children in LMICs. This report covers evidence published in English; a follow-up study is under preparation focusing on evidence in five additional languages-Arabic, Chinese, French, Portuguese and Spanish.

METHODS

The intervention-outcome framework for this EGM is based on INSPIRE-Seven Strategies for Ending Violence against Children, published by WHO and other partners in 2016. The seven strategies include implementation and enforcement of laws; norms and values, safe environment; parent-child and caregiver support; income and economic strengthening; response and support services; education and life skills. The search included both academic and grey literature available online. We included impact evaluations and systematic reviews that assessed the effectiveness of interventions to reduce interpersonal violence against children (0-18 years) in LMICs (World Bank, 2018b). Interventions targeting subpopulation of parents, teachers and caregivers of 0-18 years' age group were also included. A critical appraisal of all included studies was carried out using standardised tools.

RESULTS

The map includes 152 studies published in English of which 55 are systematic reviews and 97 are impact evaluations. Most studies in the map are from Sub-Saharan Africa. Education and life skills are the most widely populated intervention area of the map followed by income and economic strengthening interventions. Very few studies measure impact on economic and social outcomes, and few conduct cost-analysis.

CONCLUSION

More studies focusing on low-income and fragile and conflict-affected settings (FCS) and studying and reporting on cost-analysis are required to address gaps in the evidence. Most interventions covered in the literature focused on addressing a wide range of forms of violence and harm, which limited understanding of how and for whom the interventions work in a given context, for specific forms of violence. More impact evaluation studies are required that assess specific forms of violence, gendered effects of interventions and on diverse social groups in a given context, utilising mixed methods.
