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...
Article
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...
Article
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...
Article
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...

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...
Article

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...
Article
Full-text available
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...
Article
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%...
Article
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...
Article
Full-text available
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...
Article
Full-text available
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...
Article
Full-text available
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...
Article
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...

Article
Full-text available
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,...
Article
Full-text available
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...
Article
Full-text available
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...
Article
Full-text available
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...

Full-text available
In the United States, more than 40% of marriages end in divorce and more than one third of intact marriages are distressed.
