Depression Clinical Trials in Los Angeles, CA

The purpose of this study is to evaluate clinical decision-making algorithms for (a) triaging to level of care and (b) adapting level of care in a low income, highly diverse sample of community college students at East Los Angeles College (ELAC). The target enrollment is 200 participants per year, for five years (N=1000). Participants are between the ages of 18 and 40 years and will be randomized into either symptom severity decision-making (SSD) or data-driven decision-making (DDD). Participants in each condition will be triaged to one of three levels of care, including self-guided online prevention, coach-guided online cognitive behavioral therapy, and clinician-delivered care. After initial triaging, level of care will be adapted throughout the entire time of the study enrollment. Participants will complete computerized assessments and self-report questionnaires as part of the study. Recruitment will take place in the first two to four months of each academic year. The total length of participation is 40 weeks. Read Less

The purpose of this study is to pilot test the feasibility, acceptability, and preliminary efficacy of healthcare provider referrals to a tax filing app within parent-child health programs to test whether such referrals can increase receipt of tax credits among low-income parents. The study will use a single-group, pre/post test design with a sample of approximately 100 women who have a child under 6 years of age. Participants will be recruited from parental-child health programs and clinics in Los Angeles and will complete surveys at baseline, immediately after tax filing season, and six months after tax filing season to assess 1) frequency of tax filing after referral (Feasibility), 2) the acceptability of the tax filing app from the perspective of users (Acceptability), and 3) pre/posttest changes to parent and child health, child development, and healthcare utilization measures for users (preliminary efficacy).

The purpose of this study is to evaluate the efficacy and mediators of change in Positive Affect Treatment, a psychotherapy specifically aimed at enhancing reward sensitivity in individuals with low positive affect (a core feature of anhedonia) in the context of depression or anxiety. Target enrollment is 100 male and female participants with low positive affect and depression or anxiety and impaired functioning, between the ages of 18 and 65 years, who will be randomized to either Positive Affect Treatment or Negative Affect Treatment (designed to reduce threat sensitivity). Participants will complete laboratory tests, psychiatric assessments, and self-report questionnaires as part of the study. The total length of participation is around 5 months. Read Less

The purpose of this study is to use an experimental inflammatory challenge to examine whether older adults with symptoms of anxiety experience loss of pleasure or loss of motivation when they are exposed to inflammation. Loss of pleasure or loss of motivation will be evaluated using self-report questionnaires, computer tasks, and during a brain scan. Read Less

Late-life depression is a significant public health concern, and effective interventions for prevention and treatment are needed. Insomnia and inflammation are modifiable targets for depression prevention, and this study is significant in using an experimental approach (i.e., inflammatory challenge) to probe acute inflammatory- and depression responses as a function of insomnia, which will inform identification of molecular targets for pharmacologic interventions, and improvement of insomnia treatments to prevent depression in older adults.

The goal of this study is to estimate the direct, causal impact of medical debt on health care utilization, mental health, and wellbeing of patients. The investigators will conduct a survey to measure the impact of the debt forgiveness on health care use, mental health, and wellbeing. The survey will be administered to approximately 17,000 subjects of a recent medical financial intervention. In that prior intervention, a non-profit charity, RIP Medical Debt, purchased and abolished medical debt for a randomly selected about 6,000 (out of the 17,000) individuals. In this current protocol, the investigators will administer the survey, and will compare surveyed outcomes of subjects who received and did not receive the intervention. Read Less
