RESUMO

INTRODUCTION: Social anxiety disorder (SAD) has been characterized by deficits in social motivation and lack of reactivity to pleasurable stimuli (i.e., positive affect; [PA]). Recent neuroimaging work has shifted toward examining positively valenced motivational systems in SAD focused on reward responses. However, little is known about the associations of reward connectivity and PA in individuals with SAD. As such, the purpose of the current study was to determine whether connectivity among key units of reward neurocircuitry meaningfully relate to PA and whether these key units are more heterogeneous in SAD as compared to controls. METHODS: Thirty-one participants who met diagnostic criteria for SAD and 33 control participants were included (Mage = 24.8, SD = 6.9; 55% cisgender man). Seed-based timeseries correlations were conducted in NiTime to extract region of interest (ROI) coupling correlation strength values. ANOVAs were carried out to assess whether individuals with SAD differed in ROI-to-ROI connectivity strength as compared to controls. Correlations and variance analyses were also conducted to examine the relationship between ROI-to-ROI connectivity strength and PA, as well as heterogeneity in connectivity strength and PA expression. RESULTS: Weaker connectivity between the left and right orbital frontal cortex was observed when comparing the SAD to the control group. Within the SAD group, PA was associated with several reward-related ROI couplings; however, these links were not observed among controls. Results further demonstrated that individuals with SAD had significantly more variability in reward connectivity strength as compared to controls. CONCLUSION: Overall, these results provide emergent evidence for the association between reward regions and PA in individuals with SAD. Additionally, these findings show that individuals with SAD demonstrate greater heterogeneity in reward connectivity.

RESUMO

Utilizing a novel computerized task, we aimed to examine whether social anxiety symptoms would be related to individual differences in facial emotion recognition (FER) in a sample of autistic male adolescents and young adults without intellectual disability. Results indicated that social anxiety and IQ predicted poorer FER, irrespective of specific emotion type. When probing specific effects within emotion and condition types, social anxiety impacted surprise and disgust FER during a truncated viewing condition and not full viewing condition. Collectively, results suggest that social anxiety in autism may play a larger role in FER than previously thought. Future work should consider the role of social anxiety within autism as a factor that may meaningfully relate to FER assessment and intervention.

RESUMO

The present study followed-up adolescents with social anxiety disorder (SAD) during the COVID-19 pandemic, approximately 5-years following their participation in an Attention Bias Modification Training (ABMT) program (Ollendick et al., 2019). The current study aimed to evaluate current functioning and quality of life (QoL) during the emerging adulthood period. Participants included 27 young adults who completed a randomized controlled trial of ABMT and were available for follow-up. Participants filled out self-report measures of QoL and functioning and underwent a clinical interview to assess current severity of social anxiety. Clinician-rated symptoms of SAD significantly decreased from post-treatment to 5-year follow-up. Additionally, results demonstrated that social anxiety severity was significantly related to poorer self-reported physical and psychological health as well as poorer functioning with regard to social distancing fears during COVID-19. Lastly, when evaluating change in symptoms over time, increases in social anxiety severity over a 5-year period significantly predicted worsened social distancing fears during COVID-19.

RESUMO

OBJECTIVE: Community belongingness has been shown to be related to mental health outcomes in college students; however, little work has evaluated whether community belongingness impacts treatment change, especially during the COVID-19 pandemic, when social isolation and mental health concerns are exacerbated. Accordingly, the current study evaluated community belongingness as a predictor of treatment change for anxiety and depression in a university counseling center. METHOD: Participants included 516 young adults with clinical levels of anxiety or depression who attended at least two individual therapy sessions at a university counseling center during fall 2020. Participants completed broad measures of psychosocial functioning at each session. RESULTS: Paired-samples t-tests indicated that students demonstrated significant decreases in anxiety and depression after just one session. Linear stepwise regressions revealed that community belongingness was a significant predictor of symptom improvement for both anxiety and depression. CONCLUSION: These results suggest improving community belongingness on college campuses may be a way to buffer mental health and improve treatment outcomes for students seeking psychological services. Specific clinical and educational recommendations for ways to improve community belongingness are discussed.

RESUMO

Affective immunology of the skin is a growing area; however, established protocols for measuring individual differences in cutaneous inflammation are lacking. To address this, we present a preliminary validation of Precision Implementation of Minimal Erythema Dose (PI-MED) testing as a method for measuring cutaneous inflammation. PI-MED is a recently adapted protocol, optimized for reproducibility and individual differences research, that uses ultraviolet (UV) light to evoke cutaneous erythema, or inflammatory skin reddening. PI-MED's novel UV dosage schedule produces standardized erythema responses across different skin pigmentation types and shows strong internal consistency within person and good test-retest reliability across 8-10 weeks. In line with predictions, increased PI-MED erythema was associated with heightened anhedonia, across several measures, beyond influences of non-affective covariates. While future work should further refine the dosage schedule for the lightest and darkest skin types, overall, evidence supports PI-MED as a protocol for inducing and measuring individual differences in cutaneous inflammation. Further, PI-MED-induced erythema can expand psychoneuroimmunology research by offering a complementary assessment for general inflammatory tone. This work adds to a growing body of evidence demonstrating a distinct relationship between inflammation and anhedonia.

RESUMO

This randomized controlled trial examined the effects of mindfulness on anhedonic symptoms in a sample of adults reporting high levels of chronic stress. Meditation-naïve adults (N = 68, Mage = 32, 62% female) were randomized to either an 8-week group-based MBSR intervention (N = 35), or a waitlist control group (N = 33). We hypothesized that changes in mindfulness would mediate the relationship between condition and changes in anhedonic symptoms. Additionally, the present study aimed to determine if other theoretically linked mechanisms (i.e., stress, negative affect [NA], depression) were involved in producing changes in anhedonic symptoms. Results provided evidence for full mediation of the effect of MBSR on social anhedonia through its essential mechanism of ΔMindfulness. These results highlight specificity of anhedonic symptoms targeted by MBSR, with social anhedonia symptoms being modified by changes in mindfulness whereas other anhedonic domains were not. The specificity of effects to the social anhedonia domain may be in part due to the group-based nature of MBSR. Additionally, although associative relationships were present for stress, depression, NA, and anhedonic symptoms, no mediational relationships emerged. Results presented here should be evaluated in light of study limitations, such as the reliance on self-report measures as well as a lack of information regarding cultural or geographic diversity.

RESUMO

Background: Individuals with Social Anxiety Disorder (SAD) may be at a higher risk for negative outcomes during the COVID-19 pandemic due to isolation that is both characteristic of the disorder and also potentially exacerbated by quarantine and public health restrictions. Accordingly, we evaluated emotional and behavioral responses to stress during COVID-19 and attitudes towards COVID-19 vaccine adoption in socially anxious versus non-socially anxious adults. Methods: Participants (N = 84) were young adults between 18 and 24 years of age who completed a diagnostic interview and self-report measures assessing stress, anxiety and coping responses during COVID-19. Welch's t-tests assessed group differences on mental health outcomes between the SAD versus non-SAD group, and Pearson's χ2 test evaluated COVID-19 vaccination status by group. Lastly, logistic regression examined whether SAD predicted positive COVID-19 vaccination attitude. Results: Results indicated the SAD group demonstrated significantly elevated rates of anxiety and depression as compared to individuals without SAD and had significantly increased rates of engagement in safety behaviors as well as maladaptive coping mechanisms in response to COVID-19 stress. Individuals with SAD were significantly more likely to receive or plan to receive the COVID-19 vaccine. Conclusions: The current study provides evidence that social anxiety may be a significant factor associated with the impact of COVID-19 as well as attitudes with vaccine compliance.

RESUMO

OBJECTIVE: The present study sought to measure and internally validate neural markers of facial emotion recognition (FER) in adolescents and young adults with ASD to inform targeted intervention. METHOD: We utilized fMRI to measure patterns of brain activity among individuals with ASD (N = 21) and matched controls (CON; N = 20) 2 s prior to judgments about the identity of six distinct facial emotions (happy, sad, angry, surprised, fearful, disgust). RESULTS: Predictive modeling of fMRI data (support vector classification; SVC) identified mechanistic roles for brain regions that forecasted correct and incorrect identification of facial emotion as well as sources of errors over these decisions. BOLD signal activation in bilateral insula, anterior cingulate (ACC) and right dorsolateral prefrontal cortex (dlPFC) preceded accurate FER in both controls and ASD. Predictive modeling utilizing SVC confirmed the utility of ACC in forecasting correct decisions in controls but not ASD, and further indicated that a region within the right dlPFC was the source of a type 1 error signal in ASD (i.e. neural marker reflecting an impending correct judgment followed by an incorrect behavioral response) approximately two seconds prior to emotion judgments during fMRI. CONCLUSIONS: ACC forecasted correct decisions only among control participants. Right dlPFC was the source of a false-positive signal immediately prior to an error about the nature of a facial emotion in adolescents and young adults with ASD, potentially consistent with prior work indicating that dlPFC may play a role in attention to and regulation of emotional experience.

RESUMO

Social anxiety disorder (SAD) is a debilitating disorder that emerges during adolescence and confers a significant burden on interpersonal functioning. Currently available diagnostic interviews are lengthy and generally require clinically-trained experts to administer. Consequently, the identification of clinically valid self-report measures of social anxiety is necessary for streamlining assessment processes and routine outcome monitoring of adolescent social anxiety symptoms. Accordingly, the present study establishes the psychometric properties and predictive utility of the Severity Measure for Social Anxiety Disorder (SMSAD). Participants included 58 adolescents between 12 and 16 years of age who met diagnostic criteria for SAD. In addition to the SMSAD and other self-report measures, clinician and parent reports were obtained. Findings support the reliability and validity of the SMSAD, and highlight the clinical utility of this measure in comparison to previously validated measures of social anxiety. Overall, results indicate that the SMSAD is a valid and reliable measure for assessing and routinely tracking social anxiety symptoms in adolescents.

RESUMO

Prior work has established a robust association between childhood maltreatment and systemic inflammatory activation later in life; however, the mechanisms involved in this process remain incompletely understood. The purpose of this investigation was to examine potential mechanistic roles for social anxiety (SA) symptoms and low positive affect (PA) in the path from childhood maltreatment to elevations in circulating interleukin (IL)-6, a common biomarker of inflammatory activation. In addition, building on prior work establishing linkages between mindful awareness and reductions in systemic inflammation, we examined the potential role of trait mindfulness as a moderator of the relationships among childhood maltreatment, SA, low PA, and IL-6. A serial mediation model utilizing a large epidemiologic dataset (final N â€‹= â€‹527) supported our central hypothesis that the direct effect of childhood maltreatment on IL-6 was fully serially statistically mediated by SA symptoms and low PA (but not high negative affect). Additionally, results indicated that individuals falling in the upper versus lower quartiles of SA symptoms demonstrated significantly elevated concentrations of IL-6, a finding that has not been previously reported. Trait mindfulness moderated the association between low PA and IL-6, to the exclusion of any paths related to negative affect. Additionally, results indicated that the effect of child maltreatment on IL-6 bypasses SA to indirectly impact IL-6 via negative affect. Overall, we conclude that childhood maltreatment and SA symptoms have a significant influence on IL-6, albeit indirectly via low PA, and the influence of PA on IL-6 may be uniquely susceptible to influence by individual differences in mindfulness.

RESUMO

Despite being multifaceted in nature, positive emotional (PE) experiences often are studied using only global PE ratings, and measures assessing more specific PE facets do not converge in their assessment approaches. To address these issues, we examined hierarchical factor structures of ratings of positive emotionality, which reflect propensities toward experiencing PE, in both online community adult (N = 375) and undergraduate (N = 447) samples. Preregistered analyses indicated (a) a broad distinction between tendencies to experience social affection and other PE types, and that (b) PE ratings can be differentiated by as many as four replicable factors of Joviality, Social Affection, Serenity, and Attentiveness. These PE dimensions were associated with distinct personality and psychopathology profiles. Examples of these distinctive associations included Joviality displaying robust positive associations with grandiosity and exhibitionism; conversely, although Social Affection and Joviality were strongly correlated, Social Affection showed associations in the opposite direction with grandiosity and exhibitionism. Other notable results include Serenity (e.g., feeling relaxed) showing negative associations with negative emotionality at a magnitude indicating that Serenity may reflect low levels of negative emotionality to a considerable degree. Collectively, these results highlight the need to consider distinct PE facets in addition to global PE ratings when assessing PE, as important nuance may be lost otherwise. Furthermore, our results indicate the need for additional research clarifying PE structure at different levels of abstraction to inform future measure development efforts and assessment approaches.

RESUMO

The purposes of this brief integrative review are to identify and critically evaluate recent work in the area of parenting processes that are disproportionately observed among parents with social anxiety disorder (SAD) that may ultimately increase risk among offspring, and to further link these processes to specific targets for intervention. Accordingly, we first evaluate the relevance of specific parenting styles as they pertain to increased risk of developing SAD among offspring. Second, we link these parenting processes to observations of certain unfavorable consequences among socially anxious youth, such as low perceived autonomy and poorer social skills. Finally, in light of these consequences we extend our conclusions into potentially modifiable targets among parents with SAD, focusing on the enhancement of autonomy and facilitating offspring's normative period of transition into independence during adolescence. Overall, we conclude that parenting behaviors commonly observed among adults with SAD, such as overcontrol and low parental warmth, likely have a direct impact on the development of social anxiety symptoms among their children. However, these parenting behaviors are plausibly modifiable and therefore repurposing existing interventions for use among parents with SAD in conjunction with interventions with their offspring is likely to provide direct clinical benefit.

RESUMO

Social anxiety disorder (SAD) is a debilitating and often chronic psychiatric disorder that typically onsets during early adolescence. Cognitive behavior therapy (CBT), the current "gold-standard" treatment for SAD, tends to focus on threat- and fear-based systems hypothesized to maintain the disorder. Despite this targeted approach, SAD ranks among the least responsive anxiety disorders to CBT in adolescent samples, with a considerable proportion of individuals still reporting clinically significant symptoms following treatment, suggesting that the CBT-family of interventions may not fully target precipitating or maintaining factors of the disorder. This gap in efficacy highlights the need to consider new therapeutic modalities. Accordingly, this brief review critically evaluates the emergent literature supporting the use of mindfulness-based interventions (MBIs) for treating adolescent SAD. MBIs may be particularly relevant for addressing maintaining factors within this diagnosis, as they may target and interrupt cycles of avoidance and de-motivation. Despite limitations in the relative lack of randomized controlled trials (RCTs) on this topic, a unique convergence of factors emerge from the extant literature that support the notion that MBIs may hold particular promise for attenuating symptoms of SAD in adolescents. These factors include: (1) MBIs demonstrate the ability to directly engage symptoms of SAD; (2) MBIs also show consistent reduction of anxiety, including symptoms of social anxiety in adolescent populations; and (3) MBIs demonstrate high rates of feasibility and acceptability in anxious adolescent samples. We briefly review each topic and conclude that MBIs are an encouraging treatment approach for reducing symptoms of social anxiety in adolescents. However, given the lack of research within MBIs for adolescent SAD in particular, more research is needed to determine if MBIs are more advantageous than other current treatment approaches.

RESUMO

BACKGROUND: Most measures of anxious avoidance are limited to disorder-specific mechanisms and ignore the measurement of courage/approach responding in confronting fearful situations. AIMS: The purpose of the present study was to construct and validate a self-report assessment of the tendency towards avoidant or approach responding in fearful situations, the Response to Fearful Situations Scale (RFSS). METHOD AND RESULTS: In Study 1 (n = 241), exploratory factor analysis resulted in two factors, avoidance and approach. Study 2 (n = 423) replicated the two-factor structure and established test-re-test reliability. In Study 3 (n = 44), the RFSS demonstrated predictive validity on a behavioural avoidance task. In Studies 4 (n = 253) and 5 (n = 256), the RFSS was associated with clinical symptoms above existing measures of avoidance. DISCUSSION: These results validate the use of the RFSS as a transdiagnostic measure of avoidance and approach.

RESUMO

Social anxiety disorder (SAD) is a common and serious psychiatric condition that typically emerges during adolescence and persists into adulthood if left untreated. Prevailing interventions focus on modulating threat and arousal systems but produce only modest rates of remission. This gap in efficacy suggests that most mainstream treatment concepts do not sufficiently target core processes involved in the onset and maintenance of SAD. This idea has further driven the development of new theoretical models that target dopamine (DA)-driven reward circuitry and motivational deficits that appear to be systematically altered in SAD. Most of the available data linking systemic alterations in DA neurobiology to SAD in humans, although abundant, remains at the level of correlational evidence. Accordingly, the purpose of this brief review is to critically evaluate the relevance of experimental work in rodent models that link details of DA function to symptoms of social anxiety. We conclude that, despite certain systematic limitations inherent in animal models, these approaches provide useful insights into human biomarkers of social anxiety including that (1) adolescence may serve as a critical period for the convergence of neurobiological and environmental factors that modify future expectations about social reward through experience dependent changes in DA-ergic circuitry, (2) females may show unique susceptibility to social anxiety symptoms when encountering relational instability that influences DA-related neural processes, and (3) separate from fear and arousal systems, the functional neurobiology of central DA systems contribute uniquely to susceptibility and maintenance of anhedonic factors relevant to human models of SAD.

RESUMO

OBJECTIVE: Cognitive models of social anxiety disorder propose that maladaptive safety behaviors (SBs; i.e., behaviors intended to avoid, prevent, or manage threat) play an important maintaining role in the disorder. Though targeting these behaviors for elimination is one component of contemporary cognitive-behavioral therapies for social anxiety, it has rarely been examined as a specific treatment strategy, and, to our knowledge, it has not yet been examined in isolation as an intervention for social anxiety. The current study evaluated an SB reduction intervention for social anxiety that consisted of brief text message reminders. METHOD: Individuals with elevated social anxiety (N = 94) were recruited from across the United States and randomized to receive one of two 1-month text message interventions consisting of 16 text message reminders to avoid SBs or focus on the present. Symptoms were assessed at pre- and posttreatment, as well as at 1-month follow-up. RESULTS: Both treatments were associated with substantial symptom reduction. Compared to the present-focused text message condition, SB elimination led to lower SB frequency at posttreatment (sr² = .044, p = .048) and lower social anxiety at follow-up (sr² = .096, p = .005). CONCLUSIONS: These preliminary findings provide novel evidence for the importance of SBs in social anxiety and suggest text message SB reduction may be an effective, highly accessible intervention for individuals with social anxiety.

RESUMO

Computerized interpretation bias modification (IBM) programs show promise for the treatment of anxiety disorders, though they have rarely been compared to active treatments. The goal of the present study was to compare the efficacy of IBM to progressive muscle relaxation (PMR) for the treatment of social anxiety disorder (SAD). Sixty-four participants with SAD were recruited from across the United States and randomly assigned to 8 internet-delivered twice-weekly sessions of IBM or PMR. Participants were administered assessments of primary symptom outcomes and interpersonal suicide risk factors at posttreatment and 3-month follow-up. IBM led to significantly lower negative interpretation bias than PMR at posttreatment but not follow-up. Both conditions experienced comparable reductions in social anxiety from pretreatment to follow-up (IBM d = 1.37, PMR d = 1.28). They also experienced significant reductions in depression and general anxiety that did not differ from one another. Additionally, IBM led to greater reductions in thwarted belongingness than PMR at posttreatment but not follow-up. Overall, these findings suggest IBM is not more effective than PMR for reducing social anxiety, though there was some evidence of its superiority in decreasing suicide risk. Limitations and directions for future research are discussed.

RESUMO

Interpretation Bias Modification (IBM) interventions have been effective in reducing negative interpretation biases theorized to underlie depressive psychopathology. Although these programs have been highlighted as potential short-term interventions for depression, mixed evidence has been found for their effects on depressive symptoms. There is a need to examine attitudes towards training as well as individual difference factors that may impact symptom outcomes for IBM depression interventions. Seventy-two dysphoric young adults were randomly assigned to receive either an IBM targeting negative interpretation bias in personal evaluations or interpersonal situations or a healthy video control (HVC) condition. Compared to those who received HVC, participants in the IBM condition reported lower negative interpretation bias at posttreatment. No differences between conditions were found for symptom outcomes. Greater perceived treatment credibility and expectancy were associated with better treatment outcomes for both the IBM and HVC groups. Within the IBM group, a greater tendency toward assimilation with treatment scenarios was significantly associated with better treatment outcomes for both depressive and anger symptoms. This effect was unique from treatment credibility and expectancy. Pretreatment psychological reactance did not predict treatment response for either condition. Implications and future research directions are discussed.

RESUMO

Contamination fear and washing compulsions are among the most common symptoms of obsessive compulsive disorder (OCD). Though these symptoms have traditionally been viewed as being driven by a desire to avoid harm, recent research has highlighted the importance of feelings of incompleteness (INC) or not-just right experiences (NJREs) in this symptom dimension. However, no study to date has examined the extent to which INC/NJREs may be associated with treatment response for contamination symptoms. The current study used a multi-method approach to examine the role of INC/NJREs in treatment of contamination symptoms. Participants (n = 88) with elevated contamination symptoms, half of whom met for an OCD diagnosis, engaged in three sessions of exposure and response prevention (ERP) targeting contamination fears, and completed self-report and in vivo measures of INC/NJRES and contamination symptoms. ERP was associated with significant reductions in INC/NJREs. Further, changes in INC were associated with changes in contamination symptoms, independent of changes in harm avoidance. Greater discomfort in response to an in vivo NJRE task at pre-treatment predicted poor treatment response, though a self-report measure of INC did not predict response. These findings provide novel evidence for the importance of INC/NJREs in contamination-based OCD and its treatment.

RESUMO

Disgust is a universal emotion that has received recent empirical attention for its potential role in various forms of psychopathology. We conducted two studies using varying methods to explore the relationship between disgust propensity, a construct related to obsessive-compulsive symptomatology, and symptoms of body dysmorphic disorder (BDD). Study 1 found a significant and unique (i.e., above and beyond co-occurring depression and anxiety) relationship between higher disgust propensity and more severe BDD symptoms, as measured by a standardized self-report and via an in-vivo task aimed at eliciting BDD-related concerns (N = 200). In Study 2, a clinical sample of individuals with BDD (N = 50) reported higher disgust propensity compared to mentally healthy controls (N = 36). This finding remained significant when controlling for depression and anxiety. Findings are the first to our knowledge to demonstrate a relationship between disgust propensity and BDD symptoms and provide directions for future research exploring the role of disgust in BDD.
