Systematic Review on Digital-based Mindfulness Platforms for Children and Adolescents

SES Lab Graduate Student Lead: Joanna Guan

What is the study about?

The number of digital mindfulness platforms has been growing exponentially in both academic and industry spaces. However, the definition of mindfulness and types of meditation practices across these platforms also vary drastically despite the general focus on mindfulness meditations. The systematic review aims to examine the current literature for interventions with children and adolescents that include a digital mindfulness component to understand what these interventions are and the psychological outcomes that are being tested. 

Food Security and Stress in College Students

SES Lab Graduate Student Lead: Geneva Jost

What is this study about? 

Lack of consistent access to nutritious food, or food insecurity, is an all too common stressor for college students. The experience of food insecurity can have consequences for students' mental health and well-being. This project seeks to examine the relationship between stress and food insecurity, understanding the impacts of receiving food assistance, and identifying barriers to accessing basic needs resources. This work is generously supported by funding from the Center for Economic Justice and Action. 

Loneliness, Personality, and Parent-Child Relationships Across Age and Culture

SES Lab Graduate Student Leads: Geneva Jost and Rose McLaughlin

What is this study about?  

This collaborative study with researchers from the Universidad del Desarrollo investigates personality and parent-child relationship factors as predictors of loneliness in college-age students and adolescents (ages 11-15). In this work, we examine similarities and differences in the experience of loneliness in the United States and Chile.

Biobehavioral Project

SES Lab Graduate Student Lead: Sally Hang

What is this study about?  

Stress responses have been theorized to activate two primary social-behavioral profiles: (a) “fight-or-flight” (i.e., an increase in conflict or social withdrawal) or (b) “tend-and-befriend” i.e., an increase in prosocial and affiliative behavior (Taylor et al., 2000).  This project aims to investigate if biological, personality, and relationship characteristics differentiate these two social-behavioral stress response profiles. Studying these factors’ convergence would help to build a more comprehensive understanding of how social exclusion affects later rates of social disconnection and loneliness. The present study will use data from the California Families Project, a long-term, longitudinal study of Mexican-origin youth.

Wearables Project 

SES Lab Graduate Student Lead: Sally Hang

What is this study about?  

In collaboration with the ASEEC lab directed by Dr. Houman Homayoun, the goal of this project is to demonstrate that accurate, individualized prediction of elevated stress can be achieved through the application of cutting-edge machine learning algorithms applied to wearable technology that is equipped with physiological sensors that measure heart rate (HR), heart rate variability (HRV), photoplethysmography (PPG), Oxygen Saturation (SpO2), physical movement (accelerometer), temperature, and electrodermal activity (EDA). 

Sweat Patch Project

SES Lab Graduate Student Lead: Sally Hang

What is this study about? 

Sweat is a novel, non-invasive biomarker matrix with great applicability and may overcome circadian rhythm variations and complicated collection methods associated with other matrices such as blood, urine, or saliva. Studies have shown that common biomarkers related to inflammatory activities (e.g., Tumor Necrosis Factor-Alpha (TNF-a), interleukin 10 (IL-10), interleukin 6 (IL-10) (Hladek et al., 2018, 2019) can be measured and are acceptable in adult populations. However, little is known about whether these inflammatory biomarkers can be detected in sweat among children and adolescents and are associated with blood concentrations. Therefore, the goal of this study is to test the feasibility of using sweat patches to measure inflammatory biomarkers and validate these results with those collected from blood.

Prediction of Adolescent Depression from Prenatal and Childhood Data using Machine Learning (completed)

SES Lab Graduate Student Lead: Joanna Guan

What is this project about? 

Depression is a major cause of disability and mortality for young people worldwide and is typically first diagnosed during adolescence. In collaboration with researchers from the Department of Computer Science, we leveraged the Avon Longitudinal Study of Parents and Children (ALSPAC) birth cohort study to develop a machine learning framework for predicting adolescent depression occurring between ages 12 and 18 years using environmental, biological, and lifestyle features of the child, mother, and partner from the child’s prenatal period to age 10 years.

Biobehavioral Synchrony Project (completed)

SES Lab Graduate Student Lead: Anna Parenteau

What is this project about? 

The term synchrony refers to a state of inter-subject coupling of behavioral and neurobiological activity over time that allows us to have shared representations and shared emotional states with others. In collaboration with Radboud University Medical Centre (Radboudumc), Nijmegen, and the Jacobs Center for Productive Youth Development at the University of Zurich, this meta-analysis examines the impact of biobehavioral synchrony on cognitive outcomes in children.

Social Support Study (completed)

What was this study about? 

In this study, we looked at how social support affected the impact of stress. We invited children and their guardians to the lab to see if parents could help kids' regulate their psychological and physiological response to stressful situations.
