Perceived Need for a Faith-Based Trauma-Focused Treatment in a Sample of Forcibly Displaced Muslims.

Forcibly displaced Muslims, including refugees, internally displaced persons, and asylum seekers who have fled their homes to escape violence, conflict, and persecution, often have inequitable access to quality mental health services, despite substantial trauma exposure and high rates of posttraumatic stress disorder (PTSD). Understanding factors associated with domains of perceived need (i.e., community, individual, friends/family) for culturally-responsive, trauma-focused mental health interventions among forcibly displaced Muslims may provide insight into those most likely to seek psychological treatment. A sample of 108 forcibly displaced Muslims endorsed moderate to high perceived need across all three domains for a trauma healing group tailored for Muslim refugees. PTSD severity related to perceived individual need, regardless of locus of displacement. Among participants with minimal PTSD symptoms, those who were externally displaced had higher perceived community and friends or family need than those who were internally displaced. Findings highlight a need for culturally responsive, trauma-focused mental health services to facilitate access to mental health care for forcibly displaced Muslims.

The role of social connectedness in buffering the effects of discrimination on post-trauma cognitions in forcibly displaced Muslims.

INTRODUCTION: Among trauma-exposed, forcibly displaced Muslims, very little is known about how social connectedness, or perceived interpersonal connection and belonging, may alter the relationship between discrimination and negative posttraumatic cognitions. Discrimination may aggravate trauma psychopathology (Helms et al., 2010); however, social connectedness may buffer its negative effects (Juang & Alvarez, 2010). OBJECTIVE: We examined whether higher religious and racial/ethnic discrimination would be associated with stronger negative posttraumatic cognitions and whether stronger social connectedness may adaptively buffer this relationship. METHOD: Trauma exposed individuals (N = 99) who identified as Muslim and as a refugee, asylum seeker, or internally displaced person participated in the study. Measures of discrimination, social connection, and posttraumatic cognitions were completed. RESULTS: Higher discrimination was moderately associated with stronger negative trauma-related cognitions (r = .40, p < .001) and with lower social connectedness (r = -.32, p = .001). Social connectedness moderated the relationship between discrimination and posttraumatic cognitions, such that at lower levels of social connectedness there was a stronger relationship between discrimination and posttraumatic cognitions (-2SD: b = .32, -1SD: b = .23, M: b = .14), this was not present at higher levels of social connectedness. CONCLUSIONS: Connectedness to one's minority group may be an important protective factor by modulating the effects of discrimination on posttrauma adjustment.

A network approach to posttraumatic stress disorder: Comparing interview and self-report networks.

OBJECTIVE: Trauma-related fear (e.g., reexperiencing), impaired reward (e.g., anhedonia), and interpersonal (e.g., detachment) processes may be functionally intertwined, giving rise to chronic psychopathology after a trauma. Network analyses can help pinpoint symptom drivers and treatment targets, but studies examining posttraumatic stress disorder (PTSD) treatment-seeking individuals are lacking. METHOD: Treatment-seeking adults with primary PTSD (N = 350) completed interview and self-report measures of PTSD severity (PSS-I; PSS-SR). Self-report and interview-based networks were estimated and compared. RESULTS: Both networks suggested distinct but interconnected communities of reexperiencing and dysphoric symptoms (e.g., interpersonal detachment, numbing). Centrality profiles were strongly associated across networks (rs = .71), with cued reexperiencing and interpersonal detachment showing strong centrality. Self-reported symptoms were more interconnected, suggesting lower specificity. CONCLUSIONS: For those seeking treatment, interrelated fear and interpersonal processes may drive functional impairment in PTSD, and interview-based networks may help better delineate influential symptoms. Therapeutically, targeting cued reexperiencing and interpersonal detachment may facilitate broader symptom decreases. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Resilience is spreading: Mental health within the COVID-19 pandemic.

The COVID-19 global pandemic is in many ways unchartered mental health territory, but history would suggest that long-term resilience will be the most common outcome, even for those most directly impacted by the outbreak. We address 4 common myths about resilience and discuss ways to systematically build individual and community resiliency. Actively cultivating social support, adaptive meaning, and direct prosocial behaviors to reach the most vulnerable can have powerful resilience promoting effects.

Circulating PACAP peptide and PAC1R genotype as possible transdiagnostic biomarkers for anxiety disorders in women: a preliminary study.

Pituitary adenylate cyclase activating polypeptide (PACAP, gene Adcyap1) is a neuropeptide and hormone thought to play a critical role in stress response (Stroth et al., Ann NY Acad Sci 1220:49-59, 2011; Hashimoto et al., Curr Pharm Des 17:985-989, 2011). Research in humans implicates PACAP as a useful biomarker for the severity of psychiatric symptoms in response to psychological stressors, and work in rodent models suggests that PACAP manipulation exerts downstream effects on peripheral hormones and behaviors linked to the stress response, providing a potential therapeutic target. Prior work has also suggested a potential sex difference in PACAP effects due to differential estrogen regulation of this pathway. Therefore, we examined serum PACAP and associated PAC1R genotype in a cohort of males and females with a primary diagnosis of generalized anxiety disorder (GAD) and nonpsychiatric controls. We found that, while circulating hormone levels were not associated with a GAD diagnosis overall (p = 0.19, g = 0.25), PACAP may be associated with GAD in females (p = 0.04, g = 0.33). Additionally, among patients with GAD, the risk genotype identified in the PTSD literature (rs2267735, CC genotype) was associated with higher somatic anxiety symptom severity in females but lower somatic anxiety symptom severity in males (-3.27, 95%CI [-5.76, -0.77], adjusted p = 0.03). Taken together, the associations between the risk genotype, circulating PACAP, and somatic anxiety severity were stronger among females than males. These results indicate a potential underlying biological etiology for sex differences in stress-related anxiety disorders that warrants further study.

Effects of post-exposure naps on exposure therapy for social anxiety.

Exposure therapy for social anxiety disorder (SAD) utilizes fear extinction, a memory process enhanced by sleep. We investigated whether naps following exposure sessions might improve symptoms and biomarkers in response to social stress in adults undergoing 5-week exposure-based group SAD therapy. Thirty-two participants aged 18-39 (18 females) with SAD were randomized. Before and after treatment, participants completed the Liebowitz Social Anxiety Scale (LSAS) and underwent a Trier Social Stress Test with psychophysiological monitoring (mpTSST) that included skin conductance (SCL), electromyographic (EMG) and electrocardiographic recording, and an auditory startle procedure while anticipating the social stressor. At sessions 3 and 4, exposure was followed by either a 120-min polysomnographically monitored sleep opportunity (Nap, N = 17) or wakefulness (Wake, N = 15). Primary hypotheses about SAD symptom change (LSAS) and EMG blink-startle response failed to differ with naps, despite significant symptom improvement (LSAS) with therapy. Some secondary biomarkers, however, provided preliminary support for enhanced extinction learning with naps, with trend-level Time (pre-, post-treatment) × Arm interactions and significant reduction from pre- to post treatment in the Nap arm alone for mpTSST SCL and salivary cortisol rise. Because of the small sample size and limited sleep duration, additional well-powered studies with more robust sleep interventions are indicated.

Examining the Role of Anxiety Sensitivity in Sleep Dysfunction Across Anxiety Disorders.

Anxiety Sensitivity (AS) has been associated with sleep difficulties in certain anxiety disorder populations, but no studies have examined cross-diagnostically the role of anxiety sensitivity in sleep dysfunction. Three hundred one participants with generalized anxiety disorder (GAD), social anxiety disorder (SAD), and panic disorder (PD) completed an ancillary questionnaire-based study. Linear regression was used to examine AS and sleep dysfunction, and mediation analyses were used to examine whether AS was a mediator of the effect of primary diagnosis on sleep. AS was associated with increased sleep dysfunction across anxiety disorders, and primary anxiety disorder diagnosis was significantly associated with sleep dysfunction. However, after controlling for AS, primary diagnosis was no longer significant. AS significantly mediated the effects of PD versus SAD and of PD versus GAD on sleep dysfunction, but did not significantly mediate the effect of GAD versus SAD on sleep dysfunction. Taken together, AS appears to be a more important predictor of sleep dysfunction overall, emphasizing the cross-diagnostic nature of AS and bolstering the RDoC initiative approach for treating psychological dysfunction.
