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

Fear of positive evaluation and social affiliation in social anxiety disorder and major depression

Fear of positive evaluation (FPE) is posited as a core feature of social anxiety disorder (SAD); however, little is known about its role in interpersonal functioning. We examined relationships between FPE and responses to a standardized social affiliation paradigm designed to facilitate positive social connection with an unacquainted conversation partner (trained confederate). The sample included adults with SAD (N = 52), major depressive disorder (MDD; N = 23), comorbid SAD and MDD (N = 36), and non-psychiatric controls (N = 33). Participants completed measures assessing FPE, affect, safety behaviors, and desire for future interaction. Confederates and observers rated participant behavior and their own desire for future interaction. FPE was most elevated in the SAD and comorbid groups, followed by the MDD group, and then non-psychiatric controls. In the full sample, FPE was associated with greater self-reported anxiety and safety behavior use, lower self-reported positive affect and desire for future interaction, lower observer-rated desire for future interaction and approach behaviors, and greater observer-rated anxious behaviors. Within-group correlations revealed that associations were weaker in the SAD only and comorbid groups (cf. control and MDD only groups); however, post-hoc moderation analyses indicated that the relationships between FPE and the outcomes of interest largely held across varying levels of social anxiety and depression severity. Findings underscore the potential role of FPE as a transdiagnostic factor relevant to understanding interpersonal functioning in social anxiety and depression.

The relationship between expressive suppression, therapeutic bond, and treatment outcomes of a positive affect intervention for adults with anxiety and/or depression

Expressive suppression (ES; reducing emotional expression) is linked with reduced social connectedness in individuals with anxiety or depression. One implication is that people who use ES may have difficulty establishing a bond with their therapist which may impede clinical improvement. We examined this hypothesis in 33 adults with clinically elevated anxiety or depression receiving treatment focused on enhancing positive thoughts, emotions, and behaviors. At baseline, participants rated ES for positive and negative emotions during a standardized conversation task designed to generate connectedness. They also rated measures of early (session 3) perceived therapeutic bond and treatment outcomes (i.e. positive affect and social connectedness). ES of positive (r = -.39, p = .018), but not negative (r = .06, p = .747), emotions was negatively associated with therapeutic bond. Therapeutic bond mediated the relationship between greater ES of positive emotions during affiliation and lower post-treatment positive affect, 95% bias-corrected bootstrap confidence interval [-0.021, -0.000], adjusted for pre-treatment positive affect, as well as lower post-treatment social connectedness [-0.397, -0.015]; however, the indirect effect was not significant when accounting for pre-treatment social connectedness (p > .05). ES of positive emotions may be an important factor in the development of therapeutic bond and therefore treatment outcomes for individuals with anxiety or depression.

Validation of the Approach-Avoidance Temperament Questionnaire in Individuals with Anxiety and Depression

The Approach-Avoidance Temperament Questionnaire (ATQ) is a well-established measure assessing heightened sensitivity and reactivity to reward/positive stimuli (approach temperament) and to punishment/negative stimuli (avoidance temperament). These basic dimensions of personality are believed to be important for understanding the etiology and maintenance of anxiety and depressive disorders. Despite the ATQ's potential utility in clinical psychology research, its psychometric properties and factor structure have yet to be examined in a psychiatric sample. The aims of the present study were to 1) conduct confirmatory factor analysis to replicate the ATQ's factor structure in individuals diagnosed with an anxiety or depressive disorder (N = 244), 2) assess internal consistency and convergent and divergent validity, and 3) explore differences in approach and avoidance temperaments in individuals with versus without a diagnosis of anxiety or depression. Results confirmed the original two-factor structure of the ATQ in a clinical sample, with approach and avoidance temperaments representing orthogonal dimensions. The measure demonstrated strong internal consistency, convergent and divergent validity, and predictive validity. Individuals with anxiety and depression scored higher on avoidance items and lower on approach items compared to those without clinical diagnoses. This study supports the use of the ATQ in clinical populations.

Amplification of Positivity Treatment for Anxiety and Depression: A Randomized Experimental Therapeutics Trial Targeting Social Reward Sensitivity to Enhance Social Connectedness

BACKGROUND

Social disconnection is common and causes significant impairment in anxiety and depressive disorders, and it does not respond sufficiently to available treatments. The positive valence system supports social bond formation and maintenance but is often hyporesponsive in people with anxiety or depression. We conducted an experimental therapeutics trial to test the hypothesis that targeting positive valence processes through cognitive and behavioral strategies would enhance responsivity to social rewards, a core mechanism underlying social connectedness.

METHODS

Sixty-eight adults who endorsed clinically elevated anxiety and/or depression with social impairment were randomized 1:1:1 to 5 (n = 23) or 10 (n = 22) sessions of amplification of positivity (AMP) treatment or waitlist (n = 23). Pre- to posttreatment change in striatal activity (primary outcome) during social reward anticipation was measured using functional magnetic resonance imaging, and reactivity to a social affiliation task (secondary) and self-reported social connectedness (exploratory) were examined. Primary analyses compared AMP (doses combined) versus waitlist. A second aim was to compare the effects of different doses.

RESULTS

AMP engaged the hypothesized treatment target, leading to greater striatal activation during anticipation of social rewards versus waitlist (d = 1.01 [95% CI = 0.42-1.61]; largest striatal volume). AMP yielded larger improvements in positive affect and approach behavior during the affiliation task (but not other outcomes) and social connectedness. Larger striatal and social connectedness increases were observed for 5-session versus 10-session AMP (d range = 0.08-1.03).

CONCLUSIONS

Teaching people with anxiety or depression strategies to increase positive thoughts, behaviors, and emotions enhances activity in brain regions that govern social reward processing and promotes social connectedness. Social reward sensitivity may be a transdiagnostic target for remediating social disconnection.

Examining Safety Behavior Subtypes Across Distinct Social Contexts in Social Anxiety Disorder and Major Depression

People with social anxiety disorder (SAD) use different types of safety behaviors that have been classified as avoidance vs. impression management. The current study investigated differences in safety behavior subtype use in 132 individuals with principal diagnoses of social anxiety disorder (SAD, n = 69), major depressive disorder (MDD, n = 30), and nonpatient controls (n = 33) across two social contexts: an interpersonal relationship-building task (social affiliation) and a speech task (social performance). We examined whether diagnostic groups differed in safety behavior subtype use and whether group differences varied by social context. We also explored relationships between avoidance and impression management safety behaviors, respectively, and positive and negative valence affective and behavioral outcomes within the social affiliation and social performance contexts. Safety behavior use varied by diagnosis (SAD > MDD > nonpatient controls). The effect of diagnosis on impression management safety behavior use depended on social context: use was comparable for the principal SAD and MDD groups in the social performance context, whereas the SAD group used more impression management safety behaviors than the MDD group in the social affiliation context. Greater use of avoidance safety behaviors related to higher negative affect and anxious behaviors, and lower positive affect and approach behaviors across contexts. Impression management safety behaviors were most strongly associated with higher positive affect and approach behaviors within the social performance context. These findings underscore the potential value of assessing safety behavior subtypes across different contexts and within major depression, in addition to SAD.

Randomized controlled trial of computerized approach/avoidance training in social anxiety disorder: Neural and symptom outcomes

Social anxiety is associated with diminished automatic approach toward positive social cues that may limit the ability to connect with others. This diminished approach bias may be a modifiable treatment target. We evaluated the effects of an approach avoidance training procedure on positive emotions, social relationship outcomes, clinical symptoms, and neural indices of social approach and reward processing. Forty-five individuals with social anxiety disorder were randomized (parallel 1:1 randomization) to complete computerized Approach Positive training (n = 21) or Balanced training(n = 24). Sessions included a standardized social interaction task. Participants were blind to training group. Participants completed clinical outcome measures and functional magnetic resonance imaging at baseline and post intervention with an MRI-compatible AAT and the social incentive delay task (SID). Both groups displayed significant improvements of similar magnitude on the primary outcome of social connectedness (between group post-treatment d = -0.21) but not positive affect (d = -0.09), from before to after treatment, persisting through follow-up. Groups demonstrated significant improvements on additional outcomes including anxiety, depression, and anhedonia symptoms. Participants in Approach Positive AAT demonstrated increased activation in the thalamus and medial prefrontal cortex during social versus neutral- approach relative to Balanced AAT during the fMRI AAT. Participants in Balanced AAT showed increased activation in regions within an a priori-defined striatum region of interest mask during anticipation of social reward (vs. baseline) in the SID relative to Approach Positive AAT. At a neural processing level AAT may influence the valuation and motivations associated with positive social cues regulated by the mPFC and thalamus. NCT02136212, NIMH R00MH090243.

Childhood Trauma Predicts Positive Expressive Suppression During Social Affiliation in Adults With Anxiety and/or Depression: Implications for Social Functioning

Experiencing childhood trauma (CT) can create barriers for developing relationships and is a risk factor for anxiety and depression. Expressive suppression (ES; i.e., reducing expression associated with experiencing emotions) might explain the link between CT and relationship formation difficulties. We examined the association between (1) CT and ES during a dyadic paradigm intended to facilitate connectedness between unacquainted partners and (2) ES and desire for future interaction (DFI). Individuals with an anxiety or depressive disorder diagnosis (N = 77) interacted with a trained confederate; partners answered a series of increasingly intimate questions about themselves. Participant ES for positive and negative emotions, and participant and confederate DFI were collected during the task. Participants completed global anxiety, depression, and CT measures. CT correlated with positive (r = .35, p = .002), but not negative, ES (r = .13, p = .273). In a multiple linear regression model, CT predicted positive ES beyond symptom variables and gender, β = .318, t = 2.59, p = .012. Positive ES correlated with participant (r = -.38, p = .001) and confederate DFI (r = -.40, p<.01); and predicted participant DFI beyond symptom variables and ethnicity, β = -.358, t = -3.18, p = .002, and confederate DFI, β = -.390, t = -3.51, p = .001, beyond symptom variables. Mediation analyses suggested positive ES accounted for the relationship between greater CT severity and less desire for future interaction from participants, 95%CI [-0.26, -0.02], and confederates, [-0.38, -0.01]. Positive ES may be an important factor in the reduced capacity to form new social relationships for individuals with a history of CT, anxiety, and depression.

Examining affective reactivity as a link between suicidality and social disconnection

The link between suicidality and social disconnection is well-established. We explored possible mechanisms that may account for this link using a positive and negative valence systems framework in a clinical sample with and without suicidality (i.e., suicidal ideation and/or behaviors in the past month). Participants (N = 228) interacted with a trained confederate during a controlled conversation task designed to generate social affiliation. Participant-rated positive affect (PA) and negative affect (NA) were collected during the task (baseline, anticipation, post). Participant-rated desire for future interaction was collected after the task. We tested if (1) groups with (n = 82) and without (n = 146) suicidality differed in affect during the task and (2) whether affect accounted for the link between suicidality and desire for future interaction. Results revealed that groups differed in PA, but not NA, throughout the task. Participants with suicidality reported no significant changes in PA over the task (ps > .05); and, experienced less PA at post-task compared to those without (p = .003, d = 0.38) whereas participants without suicidality reported increased PA at post-task compared to baseline and anticipation of the task, ps < .001. Mediation analysis suggested blunted post-task PA accounted for the relationship between suicidality and less desire for future interaction, 95%CI [-2.59,-0.51]. Diminished PA reactivity during social affiliation opportunities may help explain the link between suicidality and social disconnection. Preliminary findings highlight PA as a potential mechanistic target for improving social connection for individuals at risk for suicide, though prospective and experimental research is needed.
