mHealth Mindfulness Intervention for Women with Perinatal Depression: A Feasibility Study

The primary goal of this project is to assess the feasibility of conducting a mobile-health mindfulness intervention (mHealth) study among pregnant and postpartum women with depressive symptoms. Perinatal depression has numerous adverse health consequences, including preterm delivery, negative maternal-infant interaction, and child behavior problems. We will recruit ~30 women who present symptoms of perinatal depression from the OBGYN clinics at Kaiser Permanente and use a single-arm intervention design to assess the feasibility of conducting a six-week mHealth mindfulness intervention. We will also obtain preliminary efficacy results consisting of patient-reported outcomes on depression, anxiety, perceived stress, health behaviors, mindfulness, and sleep.

A Pilot Pragmatic Trial of mHealth Mindfulness Intervention to Improve Quality of Life Among Metastatic Cancer Patients and Their Caregivers

Screening for psychosocial distress is an accreditation requirement of the Commission on Cancer, underscoring the importance of addressing cancer patients’ psychosocial needs. Mindfulness-based training is one strategy that has been shown to help cancer patients reduce distress and improve quality of life. However, logistical requirements of standard in-person mindfulness classes make it impractical for cancer patients to receive benefit. To address this issue, we have conducted a few studies that demonstrated the feasibility, acceptability, and preliminary efficacy of non-face-to-face mindfulness approaches (e.g., CD, MP3 and mobile app). Building on these studies, this project will pilot test the feasibility of implementing a mobile/online-based mindfulness program for advanced cancer patients and their caregivers in a cluster randomized trial involving six oncology clinics.

Being Present: A Feasibility Study of Audio-Based Mindfulness Meditation Intervention for Metastatic Cancer Patients and Caregiver

Based on our previous pilot study of CD-based mindfulness intervention for cancer patients, we propose to develop a mobile application and pilot test its acceptability among cancer patients and their caregivers in order to reduce stress and to improve quality of life. We will hold a focus group to obtain participants feedback regarding the mobile-based intervention, and conduct an 8-week feasibility study using the application.

Mobile App-Based Mindfulness Pilot Study for Cancer Patients and Caregivers

This pilot randomized trial will test the feasibility of a mobile-app based mindfulness intervention for cancer patients and their caregivers in order to reduce stress, and to improve quality of life and patient-provider communication.

Early Life Determinants of Accelerated Pubertal Development in Adolescent Girls

The goal of this research is to identify early life factors which influence the timing of pubertal development among adolescent girls. The first study utilizes data from the Cohort Study of Young Girls Nutrition, Environment and Transitions (CYGNET), which has been collecting detailed data on pubertal development, behavioral, environmental, and anthropometric information among 444 adolescent girls since 2005. The second study is a prospective cohort study of approximately 10,000 adolescent girls (age 8-9) within the Kaiser Permanente Northern California population. We will use Tanner stage information that has been entered into HealthConnect to identify early life risk factors of early pubertal development as well as racial/ethnic differences in the timing of pubertal development.
