Psychometric Evaluation of a Controlled Social Affiliation Paradigm: Findings From Anxiety, Depressive Disorder, and Healthy Samples.

Social impairments are common across many psychiatric conditions. Standardized dyadic assessments intended to elicit social affiliation between unacquainted partners are used to elucidate mechanisms that disrupt relationship formation and inform possible treatment targets; however, the psychometric properties of such paradigms remain poorly understood. This study evaluated the psychometric properties of a controlled social affiliation paradigm intended to induce connectedness between a target participant and trained confederate.

Computer-delivered behavioural activation and approach-avoidance training in major depression: Proof of concept and initial outcomes.

Objectives: Individuals with major depressive disorder (MDD) have problems with engaging in approach behaviour to potentially rewarding encounters, which contributes to the maintenance of depressive symptoms. Approach-avoidance training (AAT) retrains implicit approach tendencies, and behavioural activation (BA) promotes explicit approach behaviour in MDD. As a novel MDD treatment strategy, this study aimed to implement a brief, computerized version of BA integrated with implicit AAT.

Enhancing Social Connectedness in Anxiety and Depression Through Amplification of Positivity: Preliminary Treatment Outcomes and Process of Change.

Background: Anxiety and depressive disorders are often characterized by perceived social disconnection, yet evidence-based treatments produce only modest improvements in this domain. The well-established link between positive affect (PA) and social connectedness suggests that directly targeting PA in treatment may be valuable.

Method: A secondary analysis of a waitlist-controlled trial (N=29) was conducted to evaluate treatment response and process of change in social connectedness within a 10-session positive activity intervention protocol-Amplification of Positivity (AMP)-designed to increase PA in individuals seeking treatment for anxiety or depression (ClinicalTrials.

A tale of two systems: Testing a positive and negative valence systems framework to understand social disconnection across anxiety and depressive disorders.

Background: Social disconnection is a common and pernicious feature of anxiety and depressive disorders, yet is insufficiently addressed by our best available treatments. To better understand why people with anxiety and depression feel socially disconnected, we tested a positive and negative valence systems framework informed by research on how normative social connections develop and flourish.

Method: Individuals seeking treatment for anxiety or depression (N = 150) completed measures of perceived social connectedness, positive and negative valence temperament, social goals, affect, symptoms, and life satisfaction.

Facial Affect and Interpersonal Affiliation: Displays of Emotion During Relationship Formation in Social Anxiety Disorder.

Social anxiety disorder (SAD) often involves difficulty developing relationships. Facial expressions are important in relationship formation, but data are limited regarding facial display production among persons with SAD during social interaction. The current study compared facial displays of individuals diagnosed with SAD (n=41) to control participants (n=24) as they interacted with a confederate; confederates and observers then rated their desire for future interaction with participants.

The affective tie that binds: Examining the contribution of positive emotions and anxiety to relationship formation in social anxiety disorder.

Individuals with social anxiety disorder (SAD) have difficulty forming social relationships. The prevailing clinical perspective is that negative emotions such as anxiety inhibit one's capacity to develop satisfying social connections. However, empirical findings from social psychology and affective neuroscience suggest that positive emotional experiences are fundamental to establishing new social bonds.

Assessment of glutamate in striatal subregions in obsessive-compulsive disorder with proton magnetic resonance spectroscopy.

Glutamatergic signaling abnormalities in cortico-striatal circuits are hypothesized to lead to the repetitive thoughts and behaviors of obsessive-compulsive disorder (OCD). To test this hypothesis, studies have used proton magnetic resonance spectroscopy (1H MRS) to measure glutamatergic compounds in the striatum of individuals with OCD. However, no studies have used methods that could measure glutamate minimally contaminated by glutamine and γ-aminobutyric acid (GABA) in striatal subregions.

Youth in transition: life skills among perinatally HIV-infected and HIV-exposed adolescents.

Objective: To examine mastery of life skills necessary for independent adulthood among perinatally HIV-infected (PHIV+) and perinatally HIV-exposed but uninfected (PHIV-) youth.

Methods: Participants were recruited from four medical centers in New York City as part of a longitudinal study. Data for this article came from interviews of 150 PHIV+ and 95 PHIV- youth (age 13-24 years) and their caregivers.
