Clinical trials

Low income women of childbearing age are at increased risk for depression and often do not receive needed treatment. Investigators developed Mom-Net, an on-line cognitive behavioral treatment (CBT) for depression to address the needs of low income women of childbearing age. The intervention program also includes live coaching to help the mothers engage and learn the CBT material. Mom-Net has been shown to be highly effective in reducing depressive symptoms and improving parenting behavior and child adjustment, in earlier controlled trials. In this project the investigators are examining whether access to Mom-Net can be expanded by delivering it in Head Starts (HS). To address that broad question, the investigators will focus on two sets of scientific questions: 1. Implementation Questions: e.g., Can HS agencies deliver the program successfully; do HSs choose to sustain the program after the research project ends; what agency characteristics are associated with successful delivery of Mom-Net); 2. Effectiveness Questions: e.g., Does Mom-Net reduce maternal depression when delivered by Head Start agencies, with HS staff doing the coaching? Head Start agencies will be randomized to deliver either Mom-Net with the usual high-intensity coaching or with a low-intensity coaching alternative. Within each agency, depressed mothers will be randomized to receive either: 1) Mom-Net program; or 2) Treatment as Usual (TAU;) referral to community mental health providers). Mothers initially assigned to the TAU condition, will have the option of receiving Mom-Net at a later date. Mothers will participate in assessments of depressive symptoms, parenting behavior, and child adjustment at Time 1 (T1; prior to randomization); and Time 2 (T2; after the intervention period) and Time 3 (T3; one year after T1).

The changing food environment, with increasingly abundant ultra-processed food (UPF) options, may directly contribute to rising rates of obesity, though it is unknown which ingredients in UPF elevate their reinforcing nature in a way that may lead to overconsumption. The proposed study is the first to systematically examine differences in the rewarding characteristics of and physiological and metabolic responses to UPFs that are high in fat, refined carbohydrates (like sugar), or both. Understanding the biobehavioral underpinnings that enhance the reinforcing potential of ingredients in UPF (e.g., fat vs. refined carbohydrates) can inform novel intervention targets for the treatment of overeating and obesity.

To examine two different exercise programs in reducing incidence of falls among community-dwelling older adults

To determine the efficacy of a dual-task tai ji quan training therapy in reducing the incidence of falls in older adults with mild cognitive impairment.

The DISRUPT clinical trial will test two different 2-month programs to help adults with overweight/obesity (N=60) reduce their intake of ultra-processed foods (UPFs). Participants will be randomly assigned to receive standard dietary change strategies, cognitive dissonance strategies that engage them in activism against the UPF industry, or both. All participants will attend an introductory educational workshop about UPFs. If they are assigned to receive one or more of these strategies, they will attend weekly group sessions with the relevant intervention content for 7 more weeks. Groups will be held virtually.
