Salivary CRP predicts treatment response to virtual reality exposure therapy for social anxiety disorder.

BACKGROUND: Social anxiety disorder (SAD) places a profound burden on public health and individual wellbeing. Systemic inflammation may be important to the onset and maintenance of SAD, and anti-inflammatory treatments have shown promise in relieving symptoms of SAD. In the present study, we conducted secondary analyses on data from a randomized clinical trial to determine whether C-reactive protein (CRP) concentrations and social anxiety symptoms decreased over the course of virtual reality exposure therapy, and whether changes in social anxiety symptoms as a function of treatment varied as a function of CRP. METHOD: Adult participants (N = 78) with a diagnosis of SAD (59 % female) were randomized to receive exposure therapy alone, or exposure therapy supplemented with scopolamine. Social anxiety symptoms, salivary CRP, and subjective units of distress were measured across three exposure therapy sessions, at a post-treatment extinction retest, and at a 1-month follow-up. RESULTS: CRP decreased over the course of treatment, b = -0.03 (SE = 0.01), p =.02 95 %CI [-0.06, -0.004], as did all social anxiety symptom domains and subjective distress. Higher CRP was associated with greater decreases from pre-treatment to 1-month follow-up in fear, b = -0.45 (SE = 0.15), p =.004 95 %CI [-0.74, -0.15], and avoidance, b = -0.62 (SE = 0.19), p =.002 95 %CI [-1.01, -0.23], and in-session subjective distress from pre-treatment to post-treatment, b = -0.42 (SE = 0.21), p =.05 95 %CI [-0.83, -0.001]. However, declines in CRP were not correlated with declines in fear, r = -0.07, p =.61, or avoidance, r = -0.10, p =.49, within-persons. CONCLUSIONS: Virtual reality exposure therapy may be associated with an improvement in systemic inflammation in patients with severe SAD. Pre-treatment CRP may also be of value in predicting which patients stand to benefit the most from this treatment.

Predictors of Adolescent Resilience During the COVID-19 Pandemic in a Community Sample of Hispanic and Latinx Youth: Expressive Suppression and Social Support.

The COVID-19 pandemic has created unprecedented disruptions in the daily lives and mental health of adolescents. Less attention has been given to the psychosocial resources that may mitigate the impact of COVID-19 on adolescent mental health, particularly among minoritized populations. In the present study, 259 youth (aged 11-18) were recruited from a community center for integrated prevention and intervention services in a predominantly Latinx and Hispanic community. Youth completed questionnaires about the impact COVID-19 has had on their lives, psychosocial resources (humor, optimism, emotion regulation, social support), and psychiatric symptoms (depressive symptoms, anxiety symptoms, sleep disturbances, aggression). After accounting for age, sex, and exposure to early life adversity, higher reported COVID-19 impact was associated with more depressive symptoms, b = 6.37 (SE = 1.67), 95% CI [3.08, 9.66], p < 0.001, more anxiety symptoms, b = 9.97 (SE = 1.63), 95% CI [6.75, 13.18], p < 0.001, and more sleep disturbances, b = 1.24 (SE = 0.34), 95% CI [0.57, 1.91], p < 0.001. Youth that reported infrequent expressive suppression and the lowest scores on giving social support were at the greatest risk for aggressive behavior in the context of high COVID-19 impact, ps < 0.007. Increasing emotion regulation skills, such as expressive suppression, and opportunities to give social support may promote resilience among high risk youth in the context of this ongoing community stressor.
