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).

Religious coping, perceived discrimination, and posttraumatic growth in an international sample of forcibly displaced Muslims.

Displaced persons are exposed to trauma and experience posttraumatic stress symptoms (PTS). Many displaced Muslims come from communities that rely on religious practices to cope with traumatic experiences, and religious coping has been identified as predictive of posttraumatic growth (PTG). Discrimination may contribute to increased PTS and promote in-group identification. In this study, we hypothesized that perceived discrimination would enhance the relationship between religious coping and PTG. Results indicated that religious coping predicted PTG, but the overall interaction with discrimination was not significant. However, probing moderating effects at discrete levels of discrimination yielded enhanced relationship between religious coping and PTG at its mean and above until reaching the highest values of discrimination. For individuals who experience moderate to high levels of discrimination, religious coping increased PTG. These findings highlight the essential role of religious coping in promoting growth for many Muslims exposed to forced migration and elevated levels of discrimination.

Differences in Posttraumatic and Psychosocial Outcomes Among Refugees, Asylum Seekers, and Internally Displaced Persons.

Refugees, asylum seekers, and internally displaced persons differ in their experiences, potentially affecting posttraumatic outcomes such as posttraumatic stress disorder (PTSD) symptoms, posttraumatic cognitions, and posttraumatic growth (PTG), as well as psychosocial outcomes such as social connection, discrimination, and well-being. We explored these differences in a sample of N = 112 Muslim displaced persons. Results from planned contrasts indicated that refugees reported more PTSD symptoms (t[46.63] = 3.04, p = 0.004, d = 0.77) and more PTG (t[94] = 2.71, p = 0.008, d = 0.61) than asylum seekers. Higher posttraumatic cognitions predicted less social connections across displacement immigration category. The strength of this relationship was more pronounced for asylum seekers than refugees (b = -0.43, p = 0.014). Refugees may focus more on direct threats from others, resulting in more PTSD symptoms, whereas asylum seekers' uncertainty may pose a greater threat, exacerbating posttraumatic beliefs that drive social disconnection.

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.

Circulating levels of oxytocin may be elevated in complicated grief: a pilot study.

Complicated grief (CG) is a debilitating syndrome characterized by persisting and intense distress and impairment after the death of a loved one. The biological mechanisms associated with this syndrome remain unclear but may involve neurobiological pathways implicated in the stress response and attachment systems. The neuropeptide oxytocin has been implicated in attachment and social behaviour, and loss of social bonds has been associated with disruptions in oxytocin signalling. Furthermore, prior research has reported associations between circulating oxytocin and other mental illnesses, including depression. The present pilot study aimed to examine plasma levels of oxytocin in bereaved adults with primary CG (n = 47) compared to age- and sex-matched bereaved individuals with primary Major Depressive Disorder (MDD) (n = 46), and bereaved individuals without any mental disorder (n = 46). In unadjusted analyses comparing groups according to primary diagnosis, oxytocin levels were significantly higher for primary CG compared to primary MDD (p = 0.013), but not compared to bereaved controls (p = 0.069). In adjusted regression models, having a primary or probable (Inventory of Complicated Grief ≥ 30) diagnosis of CG was associated with significantly higher oxytocin levels (p = 0.001). While additional research is needed, findings from our pilot study provide preliminary support for recent conceptualizations of CG implicating a role for oxytocin and the attachment system. Importantly, these findings contribute to the limited current knowledge about possible biological correlates of CG.

El duelo complicado (DC) es un síndrome debilitante caracterizado por intenso y persistente malestar y discapacidad, luego de la muerte de un ser querido. Los mecanismos biológicos asociados con este síndrome no están claros, pero pueden involucrar vías neurobiológicas implicadas en la respuesta al estrés y sistemas de apego. El neuropéptido oxitocina ha sido implicado en el apego y el comportamiento social, y la pérdida de vínculos sociales ha sido asociada a disrupciones en la señal de oxitocina. Más aún, la investigación previa ha reportado asociaciones entre la oxitocina circulante y otras enfermedades mentales, incluyendo depresión. El presente estudio piloto apuntó a examinar los niveles plasmáticos de oxitocina en adultos en duelo con DC primario (n = 47), comparados con personas con Trastorno Depresivo Mayor (TDM) primario emparejados por edad y sexo (n = 46), y con personas en duelo sin ningún trastorno mental (n = 46). En los análisis sin ajustar que compararon grupos de acuerdo al diagnóstico primario, los niveles de oxitocina fueron significativamente mayores para el DG primario, en comparación a TDM primario (p = 0.013), pero no en la comparación con controles en duelo (p = 0.069). En los modelos de regresión ajustados, el tener un diagnóstico primario o probable de DC (Inventario de Duelo Complicado ≥ 30) fue asociado a niveles significativamente mayores de oxitocina (p = 0.001). A pesar de que se requiere mayor investigación, los hallazgos de nuestro estudio piloto proveen soporte preliminar a las recientes conceptualizaciones del DC que implican un rol de la oxitocina y el sistema de apego. Importantemente, estos hallazgos contribuyen al limitado conocimiento actual acerca de los posibles correlatos biológicos del DC.

Influence of intranasal oxytocin on fear consolidation in healthy humans.

BACKGROUND: Although recent data in healthy humans suggestthat treatment with intranasal oxytocin (OT) may facilitate extinction recall,to date, little is known about the effects of OT on memory consolidationprocesses. AIM: To examine the effect of intranasal administration of OT compared with placebo on memory consolidation blockade of a de novo fear memory in a classical 2-day fear conditioning procedure. RESULTS: There were no significant differences between the OT and the placebo groups on the first two extinction trials (mean (SD)=0.01 (0.39) vs 0.15 (0.31), t=-1.092, p=0.28). Similarly, during early extinction, analysis of variance for repeated measures failed to show significant main effects of extinction trials: trials (F(4, 112)=1.58, p=0.18), drug (F(1, 112)=0.13, p=0.72) or drug × trials interaction (F(4, 112)=0.76, p=0.56). CONCLUSION: Our results suggest that OT administered in a double-blind fashion immediately after fear conditioning does not significantly reduce consolidation of fear learning as measured by a differential skin conductance response tested at the beginning of extinction.

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.
