Ecological Momentary Assessment of State-Dependent Decision-Making and Metacognition Across a Psychopathology Continuum

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.

Evaluation of Emotion-related Salivary Molecular Biomarkers

Recent studies show that emotional states can be discriminated by physiological responses. This physiological regulation results from the action of enzymes and hormones that represent the activity of the autonomic nervous system. The measurement of specific biomarkers, using non-invasive biological tests in saliva, would therefore provide physiological data on an individual's emotional state in response to stimuli, particularly olfactory stimuli.

Effects of Virtual Reality With Multisensory Stimulation on Emotional and Behavioral Disorders in Individuals With Acquired Brain Injury and Disability Requiring Institutional Care: a Single Case Experimental Design (SCED) Study.

Acquired brain injuries (ABIs) frequently cause emotional and behavioral disorders that impair independence and quality of life, particularly in institutions. Virtual reality (VR), already used in various mental and neurological disorders, offers therapeutic potential that remains largely unexplored in this context. Multisensory devices offer enhanced immersion that can potentially increase the relaxation and calming effect. Their use in specialized care home (SCH) could provide additional support for care. The main objective of the study is to measure the effect of an 8-week multisensory VR relaxation program on the most significant emotional and behavioral disorders in adults with acquired brain injury living in SCH. The SCED method with multiple baselines across subjects (ABA) is used with three adult residents with ABCI and behavioral disorders living in SCH. The study consists of three phases (baseline, intervention, follow-up), during which the three main emotional and behavioral disorders of each resident are assessed weekly based on observations made throughout the week. Additional measures include the assessment of the socio-emotional profile by the care team (ECCSEG) and the emotional distress experienced by residents (QOLIBRI), collected twice per phase. The intervention consists of eight weeks of VR relaxation (VirtySens®), with two 15-minute sessions per week. All measurements taken during the experiment will be anonymized and used only by the investigators, who are fully aware of the European GDPR (General Data Protection Regulation) concerning the protection of personal data.

Cardiovascular Effects of Grieving

Self-affirmation (SA) theory proposes that people are motivated to maintain a positive self-image of being worthy, stable, and capable. Self-affirmation (SA) manipulations have been shown to effectively increase self-worth as well as reduce cardiovascular reactivity while enhancing cardiovascular recovery in response to stress. While SA is discussed as a way to alleviate grief, its effect on cardiovascular reactivity (CVR) and recovery to grief recall has yet to be studied within laboratory settings. This study proposes an experimental design to examine how an in-lab manipulation promoting self-affirmation can improve patients' cardiovascular responses during and after a grief recall procedure. The investigators hypothesized that grief severity (a continuous variable) interacts with condition (a categorical variable with two levels, i.e., SA intervention vs. control) to predict CV reactivity and recovery as outcomes. Primary Objective 1: To investigate effects of self-affirmation intervention on cardiovascular responses among grieving participants during and after grief recall. Secondary Objective 1: To investigate the relationship of grief severity with psychological stress.
