Prevention and Behavior Change studies

Our researchers assess behavior change models for prevention of chronic conditions. Studies address concerns ranging from clinical preventive services such as cancer screening and well-child visits, to behavioral interventions related to diet and physical activity for prevention and treatment of childhood obesity. Our scientists also work closely with our clinical partners in practice at our Southern California medical facilities to evaluate behavior change efforts in our members related to obesity, depression, heart disease, and cancer.

Care of Mental, Physical, and Substance Use Syndromes (COMPASS)

KPSC is one of nine sites throughout the country funded by an Innovation Award from the Centers of Medicare and Medicaid to implement a coordinated care model for depressed patients with cardiovascular disease. We have the following goals for this project: 1. To implement in three stages a multiple condition collaborative care management model in primary care clinics of care systems in states. 2. To demonstrate that this model improves care quality, patient experience and health, provider satisfaction, and total healthcare costs for the Medicare and Medicaid patients with the targeted conditions. 3. To develop role descriptions and training for the two new types of workers required for this model – care managers and care consultants. 4. To identify the costs and payment models needed by care systems to sustain and spread this care model.

Developing an HIV Specific-Specific Prevention Index Using Electronic Medical Record (HIV PI)

The goals of this study are to assess in HIV-infected patients, the degree of association between successful general clinical care by HIV disease-treating providers (reflected in overall adherence to recommended general prevention and screening guidelines) and higher-quality HIV-specific care and related clinical outcome.

Digital Mindfulness Based Cognitive Therapy for Perinatal Depression

Mindfulness Based Cognitive Therapy (MBCT) an 8-session in-person intervention using mindfulness meditation and cognitive-behavioral strategies, has shown effectiveness in reducing residual depressive symptoms and risk for recurrence among pregnant women with histories of depression. A digital adaptation of MBCT for pregnant women, Mindful Mood Balance for Moms (MMBFM), was recently developed to overcome access barriers to in-person groups and increase potential for scale-up in OB care settings. We will address the following aims for this study: 1) Compare the clinical effectiveness (i.e. engagement and symptom reduction) of MMBFM supported by clinician vs. peer coaches among women with a history of prior depressive episodes; 2) examine specific mechanisms of action for MMBFM participants receiving clinician vs. peer coaching; 3) examine the effects of specific implementation strategies on reach of the MMBFM program; and 4) estimate the cost-effectiveness of MMBFM supported by clinician vs. peer coaches. We hypothesize that MMBFM will be more cost-effective when supported by peer vs. clinician coaches.

Impact of Sugary Beverage Taxes on Weight and Health Outcomes after 3-5 Years

This study uses electronic health records to determine the effects of sugary beverage taxes initiated in 4 Northern California cities compared with control cities in Northern and Southern California. Outcomes include weight change trajectories and prevalence of overweight and obesity among children and adults, and incidence of diabetes among adults with prediabetes. Pre-specified sub-analyses include examining differences by race/ethnicity, age groups, and neighborhood socioeconomic status.
