Brief Summary
Background: Making decisions during daily life is a complicated behavior. Even simple choices can be affected by a range of emotions, stresses, and moods. Mental health issues such as depression and anxiety can lead people to make decisions that have negative effects on their lives. Learning how changes in feeling affect a person's decisions may help researchers find ways to help them make more positive choices. Objective: To learn how changes in a person's feelings and emotions affect their decisions. Eligibility: People aged 18 to 55 years who are healthy or who have some level of depressive, anxiety, substance-related, or addictive disorders. Design: All study activities can be done remotely; participants may use a smartphone app, a website, or telehealth. Participants will have a baseline visit. They will complete tasks that require decisions; these tasks are like games they play on their phone. They will also answer questions about their habits, how they feel, their sleep quality, and any problem behaviors. They may wear a smartwatch during the study; it will record data such as their movements and heart rate. For 12 weeks, a study app will prompt participants to respond. They will be asked to answer questions about how they are feeling, any problematic behaviors, or big life events; they will be asked to complete tasks that require making decisions. They may record a video or audio clip describing their day and how they feel. For 3 of the 12 weeks, participants will get prompts up to 6 times per day. For 9 weeks, they will get up to 3 prompts per day. They will have an end-of-study visit to discuss their experiences.

Outcome Measures
Primary Outcomes (4)
To establish the relationship between psychiatric symptom severity and the reactivity of decision-making to changes in internal state.
Dimensional approach allows for examination of the moderation effect of symptom-level severity across psychiatric diagnosis. The state-level symptom severity can also be used to infer the state dynamic.However, clinical diagnosis still serves an important role in understanding how decision making and internal state dynamics might be different for patients with psychopathology. Further, collecting clinical diagnosis can better connect knowledge gained from this protocol to existing literature.
Throughout the study, transdiagnostic measures of trait- and state-level symptom severity and clinical diagnosis determined by Structured Clinical Interview for DSM Disorders (SCID).
To identify how individual differences in metacognition might moderate the influence of internal states on decision-making.
Confidence is a standard proxy measure of metacognitive ability.
In 12 weeks of EMA, measure of metacognition derived from questionnaires and confidence ratings in decision-making tasks.
To estimate the temporal profile of internal state; the lag between changes in internal state and measurable changes in decision-making and to assess whether different aspects of decision-makings are sensitive to acute versus sustained changes i...
Time difference between a measurable change in decision-making characteristics and the most recent change in internal state can be calculated. State dynamics (acute versus sustained changes in internal state) can be identified by analyzing internal state fluctuation measures collected at different time scales and temporal proximity to significant life events.Life events of different types or characteristics might be more likely to elicit acute versus sustained changes and vice versa.
In 12 weeks of EMA, self-report of internal states in different time scale and following significant life event.
To assess the influence of naturally occurring fluctuations in internal states on value-based decision-making.
EMA allows for measures of changes in naturalistic settings. Collecting self-reported internal states and significant life events can establish an internal state timeline for modeling naturally occurring fluctuations in internal states.Cognitive-behavioral decision-making tasks are informative of value-based decision-making processes.Behaviors in these tasks can also be used for computational modeling of the (sub)processes and mechanisms of value-based decision-making, such as risk tolerance, ambiguity tolerance, impulsive choice, approach/avoidance behavior, planning, learning, goal progress, pleasure related to goal progress, and decision confidence.
In 12 weeks of EMA, self-report of internal states and significant life events as well as behaviors in established and novel cognitive-behavioral decision-making tasks.
Secondary Outcomes (2)
To inform key elements of a just-in-time adaptive intervention (JITAI)
Possible decision points jointly estimated with self-reported internal state, model predicted internal states, decision-making behavior, and symptom severity.
To predict the presence of emotional state changes using multimodal feature data
Throughout the study, physiological signals collected from biosensors, speech and facial features from audiovisual recording, and lexical and semantical features derived from free responses.
Study Arms (1)
Transdiagnostic Dimensional Cohort
