Background Text message-delivered interventions for chronic disease self-management have potential to reduce health disparities, yet limited research has explored implementing these interventions into clinical care. We partnered with safety net clinics to evaluate a texting intervention for type 2 diabetes called REACH (Rapid Encouragement/Educatio...

Background Many individuals living with chronic kidney disease (CKD) have comorbid Type 2 diabetes (T2D). We sought to explore if efficacious interventions that improve glycemic control may also have potential to reduce CKD progression. Methods REACH is a text message-delivered self-management support intervention, which focused on medication adhe...

Clinical trials indicate continuous glucose monitor (CGM) use in type 2 diabetes (T2D) can be beneficial across medication regimens and outpatient settings. CGM use in care for T2D is increasing rapidly, but little is known about predictors of CGM use in T2D. Adults (age 18-75) with T2D receiving primary care at an academic medical center enrolled...

Roughly 40% of persons with HIV (PWH) are not consistently involved in HIV care in the US. Finding out-of-care PWH is difficult, but hospitalization is common and presents an opportunity to re-engage PWH in outpatient care. The aims of this study were to (1) develop an Acceptance and Commitment Therapy (ACT)-based intervention for hospitalized, out...

Mobile phone-delivered interventions have proven effective in improving glycemic control (HbA1c) in the short term among adults with type 2 diabetes (T2D). Family systems theory suggests engaging family/friend in adults’ diabetes self-care may enhance or sustain improvements. In secondary analysis from a randomized controlled trial (N = 506), we ex...

Methods We conducted a systematic review of randomized controlled trials (RCTs) of non-pharmacological interventions that assessed the impact of...

Low-income couples tend to face more external stressors and report less stable romantic relationships compared to higher income couples. A recent nationwide randomized controlled trial of the web-based OurRelationship and ePREP programs was conducted with a sample of 742 lower income couples within 200% of the federal poverty line to help improve r...

Web-based relationship programs are effective in improving low-income couples' relationship functioning. However, little is known about: (a) whether parenting couples presenting for relationship help also have difficulties in coparenting and parenting, (b) whether relationship-focused programs can improve these two domains, and (c) whether program...

PurposeLung cancer (LC) is a highly prevalent disease with more survivors diagnosed and treated at earlier stages. There is a need to understand psychological and lifestyle behavior needs to design interventions for this population. Furthermore, understanding the needs and role of family caregivers, especially given the risks associated with second...

Objective: Web-based relationship interventions have been shown to improve relationship functioning for low-income couples, with gains maintained up through 12 months (Doss et al., 2020; Roddy et al., 2020). However, little is known about mechanisms of improvements and maintenance for these programs. Method: A sample of 742 low-income couples (Mage...

Objective: Military couples need and desire relationship interventions. Online interventions improve access; however, their effectiveness within the military population is untested. Using a subsample from a larger randomized controlled trial of OurRelationship and ePREP online relationship programs for low-income couples, this study examined basel...

Objective: Persistent post-surgical pain is common among patients undergoing surgery, is detrimental to patients' quality of life, and can precipitate long-term opioid use. The purpose of this randomized controlled trial is to assess the effects of a behavioral intervention offered prior to surgery for patients at risk for poor post-surgical outco...

Experimental tests of the association between relationship functioning and physical health are limited. Although associations are hypothesized to be partially mediated through improved psychological functioning, tests are mostly limited to lab‐based studies. The present study evaluated relational and psychological mediators of change in perceived h...

Objectives: This study updated existing meta-analyses of couple therapy that typically do not include multiple treatment modalities, various research designs, long-term outcomes, or recent studies. Eligibility Criteria: Studies published in English that reported relationship satisfaction or other outcomes of couple therapy were included; over 70%...

In recent years, same-gender group-based relationship education has emerged as a viable intervention to prevent relationship distress among same-gender couples. However, many of these programs are conducted in metropolitan areas and lack the ability to reach rural populations. The current study sought to investigate whether two wide-reaching web-ba...

Objective: Although low-income couples experience greater relationship challenges, they have limited access to effective relationship interventions. Furthermore, most previous efforts to improve low-income couples' relationships have yielded very small effects (Hawkins & Erickson, 2015). In an effort to overcome these limitations, this study inves...

Initial evidence suggests that gains in relationship functioning from brief, web-based programs are maintained through one year following the intervention; however, whether these results generalize to a low-income sample is unclear. Furthermore, previous research from in-person couple therapy suggests there may be different shapes of maintenance sl...

Relationship distress is a pervasive problem in the USA that disproportionally impacts couples with low-income levels. The goal of the present study was to evaluate the effectiveness of two online relationship interventions, OurRelationship and ePREP, both of which were supported by a paraprofessional coach, in improving mental health and physical...

Although online and app-based relationship interventions have been developed to promote relationship well-being, they require a computer, tablet, or smartphone and a high-speed data connection. Instead, text messaging may be a more cost-effective form of delivery. In the current study, 461 participants from three universities, who were mostly femal...

The current study sought to examine immediate and long-term consequences of college sexual assault (C-SA) among women with no prior sexual assault history.

Although the OurRelationship program for distressed couples has been found to statistically improve relationship and individual functioning, t...

Internet delivery of couple interventions is becoming increasingly popular; however, little is known about mechanisms of change during these interventions. One online, self-help relationship intervention-the OurRelationship program-has been shown to improve relationship satisfaction (Doss et al., 2016) during the intervention and to maintain gains...

Many children never receive treatment for their mental health symptoms-and those that do often receive it only after years of delay. Given that relationship and parenting conflict is an identified mechanism of child mental health symptoms, reducing distress in the parents' romantic relationship may help reduce this unmet need. In the current study,...

While the efficacy of couple therapy has been repeatedly demonstrated, most distressed couples do not seek treatment. To improve reach and overcome barriers to therapy, Integrative Behavioral Couple Therapy (IBCT) was translated into a web-based program, OurRelationship (OR). While both IBCT and OR have been shown to improve relationship and indivi...

Recently-developed online interventions for relationship distress show promising results; however, the degree to which paraprofessionals need to be involved with web-based interventions for relationship distress remains unclear. The present study sought to determine if varying levels of coach contact moderated gains during the online OurRelationshi...

Underserved couples (e.g., racial minorities or low-income populations) are at higher risk for relationship distress and dissolution. Although there have been large-scale efforts to improve relationships for underserved couples, these programs have resulted in high attrition and minimal effectiveness. The OurRelationship program is a brief web-base...

Objective: This meta-analysis synthesized the literature regarding the effect of therapist experience on internalizing client outcomes to evaluate the utility of lay providers in delivering treatment and to inform therapist training. Method: The analysis included 22 studies, contributing 208 effect sizes. Study and client characteristics were co...

This study compared the presenting problems of 151 couples seeking an online couple intervention for relationship distress (OurRelationship) with responses f...

In the United States, more than 40% of marriages end in divorce and more than one third of intact marriages are distressed. Unfortunately, only a minority of couples seek couple therapy to improve their relationships. Online interventions, with their increased reach and reduced costs, offer the potential to improve relationships nationwide. The onl...

Technological advances provide tremendous opportunities for couple and family interventions to overcome logistical, financial, and stigma-related barriers to treatment access. Given technology’s ability to facilitate, augment, or at times even substitute for face-to-face interventions, it is important to consider the appropriate role of different t...

Rates of child and adult sexual assault (SA) among women are staggering and place women at risk for intra- and interpersonal difficulties. However, the independent contributions of child and adult SA or the mechanisms of this risk are unknown. This study’s goal was to examine the indirect effects of child and adult SA on women’s own and partner’s r...

Relationship distress has deleterious effects on mental health, physical health, and quality of life. Although many couples report relationship distress, one barrier to seeking services is that one member of a couple may be too busy or refuse to participate. Relationship interventions offered to individuals have shown promising efficacy, but, as mo...

In-person conjoint treatments for relationship distress are effective at increasing relationship satisfaction, and newly developed online programs are showing promising results. However, couples reporting even low levels intimate partner violence (IPV) are traditionally excluded from these interventions. To improve the availability of couple-based...

The negative impacts of relationship distress on the couple, the family, and the individual are well-known. However, couples are often unable to access effective treatments to combat these effects-including many couples who might be at highest risk for relationship distress. Online self-help interventions decrease the barriers to treatment and prov...
