Trauma exposure and post-traumatic stress symptoms among Syrian refugee youth in Jordan: Social support and gender as moderators

This study assessed relations between exposure to trauma and post-traumatic stress (PTS) symptoms, and whether perceived social support from family and friends and gender moderated these associations. Syrian refugee youth (N = 418, 55.0% female) attending public schools in Jordan participated. Boys reported more age-adjusted PTS symptoms than girls. Analyses revealed that family support and gender moderated the association of trauma on PTS symptoms. For males, the benefits of family support were most evident under conditions of high traumatic stress exposure, while for females, benefits of family support were evident when no loss or injury to family members had been reported. Support from friends was not helpful for either gender. School- or family-based interventions designed to treat PTS symptoms need to consider the different needs of boys and girls, particularly within the Syrian Muslim cultural context.     

The contribution of school experience to students' resilience following a terror-related homicide

Schools have a significant effect on students' development, and serve as important social agencies for interventions for students facing disasters. However, little is known about the effect of students' school experience itself on their resilience when facing extreme negative events. The present study focused on students who were exposed to terror-related homicide with the aim of investigating the contribution of school climate resources to their resilience. Since resilience is associated not only with fewer negative outcomes, but also with positive change, the contribution of schools was studied as both inhibiting post-traumatic stress symptoms (PTS) and enhancing post-traumatic growth (PTG). A mixed-methods research design was used. The participants included 117 (52% girls) high school students (mean age = 14.54; SD = 1.49). Twenty-five of them were interviewed in addition to responding to the research questionnaires. Different aspects of the school climate were found to be associated with students' PTS and PTG, yielding two overarched factors explaining the school's role as a protective resource: sheltering and supporting. The former is associated with fewer PTS and the latter with higher PTG. The use of different resources for different forms of resilience is discussed.     

Resting autonomic activity in adults who stutter and its association with self-reports of social anxiety

PurposeThe purpose of this study was to investigate resting autonomic activity in adults who stutter (AWS) compared to adults who do not stutter (ANS) and the relationship this has on self-reports of social anxiety.MethodsThirteen AWS and 15 ANS completed the Social Interaction Anxiety Scale (SIAS; Mattick & Clark, 1998) and Brief Fear of Negative Evaluation (BFNE; Leary, 1983). Following this, measures of skin conductance levels (i.e. index of sympathetic activity) and respiratory sinus arrhythmia (i.e. index of parasympathetic activity) were taken during a 5-minute resting, baseline period. Independent sample t tests were used to assess differences between groups on self-reports of anxiety (SIAS, BFNE) and resting autonomic levels (SCL, RSA). Separate multiple regression analyses were performed in order to assess the relationship between self-reports of anxiety and autonomic measures.ResultsResults showed significantly higher mean SCL and lower mean RSA levels in the AWS compared to the ANS at resting, baseline. Regression analysis showed that self-reports from the SIAS had a significant effect on RSA levels for the AWS but not the ANS. No significant effects were found for BFNE on RSA. Nor was there a significant effect from SIAS or BFNE on SCL levels for either group.ConclusionFindings suggest that resting RSA levels may be a physiological marker for social anxiety levels in adults who stutter.     

La psychothérapie assistée par la MDMA dans la prise en charge du syndrome de stress post-traumatique

Posttraumatic stress disorder (PTSD) is estimated to remain chronic and severe for 25–50% of patients despite psychotherapeutic treatment. Part of the reasons is that patients with PTSD can have difficulties in establishing a good therapeutical alliance with the therapist. Moreover, they often fail to re-think the content of the trauma without being overwhelmed by negative emotions and tend to rely on avoidance strategies and/or to abandon the therapy. MDMA (“ecstasy”) is a drug classified as an entactogen (en “within”, tactus “touch”, and gen “produce”), an amphetamine with psychedelic properties that possesses psychopharmacological properties to overcome these issues. Indeed, MDMA triggers the release of oxytocin, which favors the establishment of interpersonal relationship based on kindness and trust. Moreover, MDMA diminishes the activity of the amygdale, allowing patients to work on challenging memories with less fear and anxiety. Finally, MDMA may also provide access to meaningful spiritual experiences, release of tensions and a sense of healing on a non-verbal level that are not completely understood. But are viewed as important by patients. Today, there is no evidence that the use of MDMA in a clinical setting has bad neurologic, psychological or cognitive consequences. Results of phase II trials in the United States and Europe confirm that MDMA favors psychotherapy's outcome without severe adverse effects. Phase III trials are underway. The Multidisciplinary Association for Psychedelic Studies (MAPS) has published online a method proposal and trains therapists in MDMA-assisted psychotherapy.ConclusionFood and Drug Administration (FDA) and European Medicines Agency (EMA) could approve this therapeutic tool in the coming years.     

Conducting Prolonged Exposure for PTSD During the COVID-19 Pandemic: Considerations for Treatment

The unprecedented effects and duration of the COVID-19 crisis are likely to elevate the population’s level of anxiety due to psychological stress, economic hardship, and social isolation. This effect may be especially potent for individuals with preexisting mental health conditions, such as posttraumatic stress disorder (PTSD). Prolonged Exposure (PE) therapy is a highly effective treatment for PTSD across trauma-exposed populations, and has been implemented effectively via telehealth. Nevertheless, PE implementation via telehealth may require specific adaptations during the COVID-19 crisis due to public health mandates calling for sheltering in place and physical distancing. This paper discusses strategies for implementing PE for PTSD during the COVID-19 pandemic, which may also be applied to other situations in which physical distancing must be considered.     

即刻消退缺损的原因分析及其神经生物学机制

即刻消退缺损(immediate extinction deficit, IED)是指在条件性恐惧习得后, 立即进行的消退训练不能长期抑制恐惧记忆的现象。IED可能与消退起始时的应激水平和事件分割等因素有关。在高应激水平下, 消退记忆的巩固受损导致IED; 而在中等或较低的应激水平条件下, 即刻消退有效但效果可能容易受事件分割的影响。IED的神经生物学机制涉及应激激活蓝斑去甲肾上腺素能系统, 去甲肾上腺素引起杏仁核基底外侧核(basolateral amygdala, BLA)过度兴奋, 然后BLA通过投射突触抑制在恐惧消退中起核心作用的内侧前额叶神经元的活动。未来研究应注意即刻消退缺损引起的长期后果, 并深入探讨如何优化即刻消退在临床上的应用。     

青少年创伤后应激障碍症状与网络成瘾症状的关系：惩罚敏感性和孤独感的中介及性别的调节

汶川地震9.5年后,对汶川县和都江堰市767名中学生进行调查,考察惩罚敏感性和孤独感在创伤后应激障碍症状和网络成瘾症状之间的多重中介作用及性别差异。结果发现：（1）PTSD症状正向预测网络成瘾症状,并分别通过惩罚敏感性、孤独感的单独中介作用及两者的链式中介作用显著预测网络成瘾症状;（2）女性的PTSD症状显著正向预测网络成瘾症状,并分别通过惩罚敏感性和孤独感间接影响网络成瘾症状;男性的网络成瘾症状仅被PTSD症状正向预测。

Comparison of Maternal Perceptions of Preterm and Fullterm Infants

We compared maternal attitudes and feelings in two groups of mother–infant dyads: 25 mothers with preterm newborns (M=30.9 weeks of gestational age) and 25 mothers with fullterm newborns (M=39.7 weeks of gestational age). Both groups were matched for infant sex, age (corrected in preterms) and birth order as well as for maternal age and education. Semi-structured interviews were used to collect data on maternal attitudes and feelings about pregnancy and the first contacts with the newborn. Mothers completed rating scales to indicate the specific behavioural problems they perceived in their infants at 6 weeks and 3 months of (corrected) age. Observations of infant responses to visual and/or auditory stimuli were made at 6 weeks and 3 months in a laboratory setting. At 3 months, each infant was administered the Bayley Scale of Mental Development. There were no differences in maternal attitudes and feelings between the two groups of mothers prior to the birth. However, significant differences appeared after birth and indicated increased anxiety in mothers of preterm infants. Significantly more 6-week-old preterm infants were perceived by their mothers as irritable and to cry more than fullterm infants. At the age of 3 months, both groups of infants differed only in terms of irritability. Differences between the two groups of mother–infant dyads, age-related changes in these differences and relationships between maternal evaluations and the laboratory-based assessments are discussed in the context of contrasts in the stability of behavioural regulation in preterm and fullterm infants.
