Enhanced Mental Reinstatement of Exposure to Improve Extinction Generalization: A Study on Claustrophobia and MRI Fear.

Fear of enclosed spaces prevents many people from receiving magnetic resonance imaging (MRI) scans. Although exposure therapy can effectively treat such fears, reductions in fear during exposure often do not generalize beyond the context in which they took place. This study tested a strategy designed to increase generalization, which involved revisiting the memory of a prior exposure to enhance retrieval of extinction learning. Forty-five participants with claustrophobia that included fear of MRI scans underwent a series of exposures lying inside a narrow cabinet. One week later, participants were randomly assigned to enhanced mental reinstatement (EMR) or control procedures. Prior to entering a mock MRI scanner, EMR participants recalled the memory of exposure training and listened to an audio recording of themselves describing what they learned, whereas control participants recalled a neutral memory. Compared to the control condition, EMR led to significantly reduced heart rate reactivity in the mock MRI scanner, but not self-reported fear or avoidance. There were no differences between conditions in claustrophobia symptoms or MRI fear at 1-month follow-up. Results suggest some benefits of mental reinstatement for improving generalization of gains following exposure training for claustrophobia, with measures of subjective fear and physiological arousal showing discordant outcomes.

Interpersonal emotion regulation questionnaire: psychometric properties of the Italian version and associations with psychopathology.

The emerging field of interpersonal emotion regulation (IER) is drawing attention to forms of emotion regulation which involve communication and social interaction as part of the regulation process. The availability of instruments to measure IER in different languages represents significant promise for future work in this field. The goal of the present study was to validate an Italian adaptation of a self-report instrument for the assessment of IER, the Interpersonal Emotion Regulation Questionnaire (IERQ; Hofmann et al., 2016). In an Italian sample (N=448), exploratory and confirmatory factor analyses confirmed the original structure comprising four factors (Enhancing Positive Affect, Perspective Taking, Soothing and Social Modelling). Correlations with other measures of emotion regulation showed good convergent validity of the questionnaire.

Anxiety and suicidality in the college student population.

Objective: This study examined symptoms of anxiety, depression and suicidality in a national sample of college students. Participants: Using national survey data from the Healthy Minds Study (HMS), a random sample from 184 U.S. campuses from fall 2016 to spring 2019 was analyzed (N = 119,875). Methods: Prevalence rates were examined with the Generalized Anxiety Disorder 7-Item scale, Patient Health Questionnaire-9 and suicidality questions. Relationships between anxiety, depression and suicidality were assessed through Spearman's correlations, the Kruskal-Wallis H test and logistic regressions. Results: Findings revealed that screening only for depression would pick up 23% of suicidal ideation, increasing to 35% when also screening for anxiety. Those with anxiety and no to minimal depression had the second highest likelihood of suicide attempt, following those with anxiety and depression. The symptom "feeling afraid something awful might happen" doubled the odds of suicidal ideation. Conclusions: College campuses may benefit from assessing particular anxiety symptoms in relation to suicide.

Biofeedback and Neurofeedback for Anxiety Disorders: A Quantitative and Qualitative Systematic Review.

Biofeedback refers to the operant training of physiological responding. Variants include electromyography (EMG), electrodermal activity (EDA), skin temperature, heart rate (HR) and heart rate variability (HRV), respiratory biofeedback of end-tidal CO2 (ETCO2), electroencephalography (EEG) signal, and blood oxygen-level dependent signal using functional magnetic resonance imaging (fMRI). This chapter presents a qualitative and quantitative systematic review of randomized controlled trials of biofeedback for anxiety disorders as defined by the 3rd through 5th editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM). Meta-analytic results indicated that biofeedback (broadly defined) is superior to wait list, but has not been shown to be superior to active treatment conditions or to conditions in which patients are trained to change their physiological responding in a countertherapeutic direction. Thus, although biofeedback appears generally efficacious for anxiety disorders, the specific effects of biofeedback cannot be distinguished from nonspecific effects of treatment. Further, significant limitations were identified in the existing literature, with the majority receiving a "weak" rating according to Effective Public Health Practice Project (EPHPP) rating system guidelines. Future directions for research are discussed.

A randomized controlled pilot trial of vilazodone for adult separation anxiety disorder.

BACKGROUND: Separation anxiety disorder was recently recognized by fifth edition of the Diagnostic and Statistical Manual of Mental Disorders as a diagnosis in adults, but no publications to date have characterized a sample of patients seeking treatment for adult separation anxiety disorder (ASAD) or assessed treatment efficacy. We hypothesized that vilazodone, a selective serotonin reuptake inhibitor (SSRI) and serotonin 1a (5HT1a ) receptor partial agonist, would have efficacy in ASAD, because SSRIs have appeared efficacious in children with mixed diagnoses including separation anxiety disorder and in animal models of separation anxiety. METHODS: In this pilot study, 24 adults (ages 18-60) with a principal diagnosis of ASAD were randomized to 12 weeks of double-blind treatment with vilazodone (n = 13) or placebo (n = 11). Outcome was assessed by an independent evaluator and self-ratings, and analyzed with mixed effect models. RESULTS: This sample was predominantly female (67%), with comorbid psychiatric disorders (58%), and adult onset of separation anxiety disorder (62%). Response rates at week 12 did not differ significantly between groups. Across all time points, the vilazodone group evidenced greater improvement on the Structured Clinical Interview for Separation Anxiety Symptoms (P = .026) and the Quality of Life Enjoyment and Satisfaction Questionnaire (P = .011), and trends toward greater improvement on the Adult Separation Anxiety Questionnaire (P = .054) and the Clinical Global Impression-Change Scale (P = .086), all with large between-group effect sizes. CONCLUSIONS: Findings demonstrate feasibility of a clinical trial in ASAD, and they suggest that vilazodone may have efficacy in the treatment of ASAD and warrants further study.

The relations of age and pubertal development with cortisol and daily stress in youth at clinical risk for psychosis.

BACKGROUND: Prodromal syndromes often begin in adolescence - a period of neurodevelopmental changes and heightened stress sensitivity. Research has shown elevated stress and cortisol in individuals at clinical high risk (CHR) for psychosis. This cross-sectional study examined relations of age and pubertal status with cortisol and self-reported stress in healthy controls (HCs) and CHR adolescents. It was hypothesized that the relations of age and pubertal stage with cortisol and stress would be more pronounced in CHR youth. METHODS: Participants were 93 HCs and 348 CHR adolescents from the North American Prodrome Longitudinal Study (NAPLS). At baseline, measures of stress (Daily Stress Inventory - DSI), Tanner stage (TS), and salivary cortisol were obtained. RESULTS: ANCOVA revealed increased DSI scores with age for both groups, and higher DSI scores in CHR adolescents than HCs, with a more pronounced difference for females. Contrary to prediction, with age controlled, HCs showed greater TS-related DSI increases. Analysis of cortisol showed no significant interactions, but a main effect of age and a trend toward higher cortisol in the CHR group. Correlations of cortisol with TS were higher in HC than CHR group. CONCLUSIONS: Stress measures increased with age in HC and CHR adolescents, and DSI scores also increased with TS in HCs. The results do not support a more pronounced age or TS increase in stress measures in CHR adolescents, but instead suggest that stress indices tend to be elevated earlier in adolescence in the CHR group. Potential determinants of findings and future directions are discussed.
