## Abstract

PROJECT SUMMARY/ABSTRACT
 The purpose of the new funding opportunity announcement, RFA-OD-17-004 for Intensive
Longitudinal Analysis of Health Behaviors: Leveraging New Technologies To Understand Health Behaviors
(U01), is to establish a cooperative agreement network to collaboratively study factors that influence key health
behaviors in the dynamic environment of individuals, using intensive longitudinal data collection and analytic
methods. Importantly, progress has been slow and frustrating in translating knowledge of the brain to new and
more effective treatments for human brain diseases such as severe mental disorders. In fact, severe mental
disorders, which include psychotic disorders, are brain diseases that are not only devastating because they
result in severe disruptions that occur early in life, but, for many, the course of illness is progressive, leading to
chronic debilitation and early mortality. Thus the need to accelerate knowledge about the factors that trigger
(or increase or decrease the likelihood) of manic and psychotic episodes, and to translate this knowledge to
more effective treatment interventions, is critical. The primary goal of the proposed “Robust Predictors of
Mania and Psychosis” is to identify biological, environmental, and social factors that trigger dangerous
mental states, particularly mania and psychosis, in individuals known to be at risk for these conditions. The
eventual goal of this work is to provide quantifiable and predictable information that can be used to scaffold
biological observations and tailor intervention strategies to maximize efficacy at the individual level. We first
develop models to predict conventional clinical measures specific to psychosis and mania using (1) digital, low-
to-minimal burden interactions through smartphones and wearables (Aim 1), and (2) measures extracted from
face and voice during in-person clinical interactions (Aim 2), work which leverages existing data we have
already collected. We will next collect one hundred person-years of pseudo-continuous multivariate behavioral
data from one hundred individuals with a psychotic disorder, to further test and validate our early observations
in a wider array of individuals with affective and non-affective psychotic disorders, who are likely to experience
illness fluctuations within a one-year timeframe, employing several strategies to optimize participant
engagement (Aim 3). We will also perform, as a representative example, a study comparing sleep, energy
expenditure, and mania symptoms over time, using data obtained in the first three aims, to quantify how the
relationship between energy expenditure and energy perception varies across our study population in ways that
could have important consequences for health behaviors (Aim 4). The main goals of this project are thus to
acquire high quality, temporally dense behavioral, cognitive, and clinical data on an important cohort of young
adult patients, not only to facilitate futur...
