Representation of Diverse Populations in Couple and Family Therapy Intervention Studies: A Systematic Review of Race/Ethnicity, Sexual Orientation, Age, and Income in the United States from 2014 to 2019

Recruitment, retention and reporting of variables related to ethnic diversity in randomised controlled trials: an umbrella review

OBJECTIVE

This umbrella review synthesises evidence on the methods used to recruit and retain ethnically diverse participants and report and analyse variables related to ethnic diversity in randomised controlled trials.

DESIGN

Umbrella review.

DATA SOURCES

Ovid MEDLINE, Ovid Embase, CINAHL, PsycINFO and Cochrane and Campbell Libraries for review papers published between 1 January 2010 and 13 May 2024.

ELIGIBILITY CRITERIA

English language systematic reviews focusing on inclusion and reporting of ethnicity variables. Methodological quality was assessed using the AMSTAR 2 tool.

RESULTS

Sixty-two systematic reviews were included. Findings point to limited representation and reporting of ethnic diversity in trials. Recruitment strategies commonly reported by the reviews were community engagement, advertisement, face-to-face recruitment, cultural targeting, clinical referral, community presentation, use of technology, incentives and research partnership with communities. Retention strategies highlighted by the reviews included frequent follow-ups on participants to check how they are doing in the study, provision of incentives, use of tailored approaches and culturally appropriate interventions. The findings point to a limited focus on the analysis of variables relevant to ethnic diversity in trials even when they are reported in trials.

CONCLUSION

Significant improvements are required in enhancing the recruitment and retention of ethnically diverse participants in trials as well as analysis and reporting of variables relating to diversity in clinical trials.

Exploring associations among baseline emotion regulation and change in relationship satisfaction among couples in a randomized controlled trial of emotionally focused therapy compared to usual care

BACKGROUND

Data from a two-arm randomized controlled trial of emotionally focused therapy (EFT) compared to usual care were used to examine whether baseline emotion regulation influences relationship satisfaction for female and male partners. This is clinically relevant as clinicians have debated whether clients' initial emotion regulation skills predict positive outcomes in EFT.

METHODS

Dyadic multilevel modeling was used to determine whether baseline emotion regulation predicted both initial levels and change in relationship satisfaction and whether that relationship differed by treatment group (i.e., EFT or usual care).

RESULTS

Baseline emotion regulation difficulties were associated with lower initial relationship satisfaction. However, baseline emotion regulation difficulties were not associated with change in relationship satisfaction over the course of treatment and this relationship did not differ by treatment group.

CONCLUSIONS

Results demonstrate that partners with diverse presentations of emotion regulation at baseline may benefit from couple therapy.

Recruitment and retention of diverse couples in relationship education with integrated economic services

Compared to higher income couples, those with low incomes experience a host of challenges and disparities in their intimate relationships, including lower levels of relationship satisfaction, higher rates of breakup of cohabiting relationships, and higher rates of divorce. In recognition of these disparities, a number of interventions targeting couples with low incomes have been developed. These interventions historically focused primarily on improving relationship skills through relationship education, but in recent years a new approach that integrates economic-focused interventions alongside relationship education has emerged. This integrated approach is intended to better address the challenges facing couples with low incomes, but the theory-driven, top-down approach to intervention development leaves open the question of whether couples with low incomes are interested in participating in a program that combines these two disparate components. The current study draws from a large randomized controlled trial of one such program (N = 879 couples) to provide descriptive information about the recruitment and retention of couples with low incomes in a study of relationship education with integrated economic services. Results indicate that it is possible to recruit a large, linguistically, and racially diverse sample of couples living with low income to participate in an integrated intervention, but the uptake of relationship-focused services was higher than the uptake of economic-focused services. Additionally, attrition over a 1-year follow-up data collection period was low but required labor-intensive efforts to reach participants for the survey. We highlight successful strategies for the recruitment and retention of diverse couples and discuss implications for future intervention efforts.

Emancipatory approaches in couples' intervention research

A lack of diversity exists in couples research with an overrepresentation of white, middle to upper income couples. Additionally, researchers often do not reflect the study sample, particularly when studying underrepresented minority and historically marginalized (URM-HM) populations. Emancipatory research practices focus on language, processes, and practices to ensure that researchers and the research they conduct honor and contribute to the empowerment of the URM-HM research participants. Therefore, in this paper, we discuss five critical considerations with recommendations for emancipatory research practices for including couples from URM-HM populations. The aim is to provide a framework for researchers to critically reflect on their work with URM-HM populations. The research practices include: (a) research positionality and reflexivity; (b) understanding of the population being served; (c) power and empowerment; (d) accountability, voice, and participant engagement; and (e) research that benefits URM-HM populations and challenges the systems that perpetuate inequities. Additionally, we present practical strategies to implement these five considerations based on our own experiences conducting community-effectiveness studies with low-income and diverse couples.

Recruitment strategies in couple intervention studies: A systematic review of recruitment methods and sample characteristics in the United States from 2015 to 2020

Including diverse participants in couple intervention studies is critical for developing an evidence base that informs best practices for all potential clients. Research has shown that subgroups of clients respond differently to different interventions and that interventions that have been adapted to fit the needs of a given population are more effective than non-adapted interventions. Unfortunately, couple intervention samples often exclude participants with marginalized identities and culturally adapted couple intervention research is limited. The lack of information about best practices for diverse client subgroups perpetuates mental and relational health disparities. We conducted a systematic review to examine recruitment strategies and sampling characteristics of diverse races/ethnicities, incomes, ages, and sexual identities. We reviewed articles published between January 2015 and December 2020. Articles were eligible for inclusion in our review if they implemented an intervention with couples in the United States. Of 4054 articles identified, 54 articles were eligible for our review. Findings suggest that couple intervention studies lack diversity across multiple identity domains (i.e., races/ethnicities, incomes, ages, and sexual identities). Further, descriptions of recruitment strategies are often vague, limiting opportunities to better understand methods used to recruit diverse samples.

A special section: Recruiting and retaining couples from underrepresented backgrounds in intervention research

This special section represents a collection of papers on recruitment and retention of couples from underrepresented backgrounds in couple intervention research. Research shows that couples from underrepresented backgrounds tend to be missing from intervention research. This gap is concerning; conclusions about the effectiveness of these interventions are not being drawn from diverse and representative samples and it may be that scholars are inadvertently creating inappropriate and inaccessible services for these couples. Recruiting and retaining these couples require specialized efforts and attention. In this summary paper, we describe (a) the origins of this special section, (b) the existing research on recruitment and retention in couple intervention research, (c) an overview of the papers in this special section, and (d) future recommendations and directions for this aspect of methodology in couple research. This collection of papers elevates the need to involve community members from the beginning, reduce barriers to access, and create recruitment materials and a service delivery environment that is specific for the target population.

Couple therapy in the 2020s: Current status and emerging developments

This paper provides a critical analysis and synthesis of the current status and emerging developments in contemporary couple therapy. Its narrative centers on the evolution of couple therapy into a prominent intervention modality and coherent body of practice. The review begins with the consideration of the field's strong empirical underpinnings derived from research on couple therapy and basic relational science. Couple therapy comprises the widely accepted method for reducing relationship distress and enhancing relationship quality. Moreover, both as a stand-alone intervention and in conjunction with other treatment formats, couple-based interventions have garnered considerable empirical support for their effectiveness in addressing a broad spectrum of specific relational dysfunctions as well as individual emotional and physical health problems. We highlight the convergence of methods through common factors, shared strategies, and remarkably similar arrangements across approaches. Our review also points to key differences among approaches, the importance of recognizing respective strengths and limitations linked to these differences, and building on differences across models when selecting and tailoring interventions for a given couple. The discussion concludes with a consideration of recent trends in the field including the impact of telehealth and related digital technologies, the expansion of specific treatments for specific problems and diverse populations, the interface of couple therapy with relationship education, and enduring challenges as well as new opportunities addressing broader systemic and global dynamics.

Couple variables predicting retention in a brief intervention and research

Therapy is an effective form of treatment for couple distress; yet, research shows that 20%-60% of couples terminate treatment prematurely. Predictors of couple retention in therapy and research are unclear, particularly for couples from marginalized populations, which has important implications for the quality and generalizability of research results, and the benefits derived from therapy are limited when participants are not retained. The purpose of this study (N = 1310) was to identify couple-level variables that predict (1) retention in a brief, two-session couple intervention (The Relationship Checkup) delivered as a home visitation program and (2) retention in research participation at 1- and 6-month follow-up. Hypotheses were tested using a two-level multi-level model. Couples are significantly less likely to be retained in the brief intervention if (1) at least one partner identifies as Asian, Pacific Islander, or Native American, (2) at least one partner identifies as Hispanic/Latinx, or (3) both partners report mental or emotional health as a concern in their relationship. Couples are significantly less likely to be retained in research if (1) at least one partner identifies as Asian, Pacific Islander, or Native American (1 month only), (2) at least one partner identifies as Hispanic/Latinx (1 and 6 months), (3) if either partner reports clinically significant relationship distress at baseline (1 and 6 months), or (4) if either partner reports relationship aggression at baseline (6 months only). These findings are discussed with relevance to clinicians and researchers to recruit and retain more diverse and marginalized participants in couple interventions and follow-up research.

A Systematic Review of Black American Same-Sex Couples Research: Laying the Groundwork for Culturally-Specific Research and Interventions

ABSTRACTThis article presents the findings of a systematic review of the empirical literature related to Black American same-sex couples (BASCs). We found 16 articles that met inclusion criteria. Most articles were published in journals that focused on interdisciplinary studies, HIV/AIDS, and couples and families' studies. Approximately 63% of the articles reported external funding support. However, only one of these grants was awarded to a Black investigator. Articles predominately focused on BASCs composed of Black sexual minority men residing in major U.S. cities. Only 25% of the articles focused on couples where both partners were Black. Most studies were cross-sectional, used convenience samples, and were reported without mention of a theoretical framework that explicated the philosophical assumptions that guided the research. The articles focused on a range of topics such as resilience, relationship dynamics, couple-level social support, rituals with extended families, and partner-health associations. The implications of these findings for advancing culturally-specific behavioral and social science health research and interventions with BASCs are presented.

Reducing mental health disparities among racially and ethnically diverse populations: A review of couple and family intervention research methods (2010-2019)

Racially and ethnically diverse and globally underserved populations continue to experience mental health disparities. The goal of this review was to examine the extent to which diverse populations were included in couple and family intervention research over the past decade and whether these studies were conducted with attention to issues of diversity. We performed a review of 271 articles reviewed in the current special issue on the efficacy and effectiveness of couple and family interventions across 11 mental health topics. Overall, only 68 of the 271 (25%) articles included predominately racial/ethnic minority samples or globally underserved populations. Among articles (n = 60) describing US-based research with racial/ethnic minority samples, there was a pattern of inattention to methodological considerations relevant to diverse populations. Although some progress was noted, more research is necessary. Specifically, we call for research that advances social justice by using critically conscious methods to promote mental health equity.
