An evaluation of survive and thrive: a 10-week group psychoeducational course for adult interpersonal trauma survivors in Scotland

Emerging evidence supports a phased approach to trauma treatment, including manualised group-based interventions, to facilitate symptom reduction resulting from complex trauma sequelae. This study investigates the efficacy of Survive and Thrive, a 10-week group psychoeducational course for adult survivors of interpersonal trauma. Between August 2019 and February 2022, participants were enrolled on the course. The Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) and Difficulties in Emotion Regulation Scale-Short Form (DERS-SF) were administered pre-intervention and immediately post-intervention. In addition, thematic analysis was applied to qualitative feedback. Results revealed significant reductions in CORE-OM and DERS-SF scores post-intervention, with minimal variability in scores attributed to group delivery (either face-to-face or online). The thematic analysis demonstrated that normalising trauma symptoms and providing coping skills positively impacted participants' experiences. At the same time, the breadth and nature of the content were observed to be an occasional barrier to engagement. In summary, this study proposes that group-based psychoeducational interventions are generally effective for those with mild-to-moderate symptoms of complex trauma. However, further evidence is needed to offer more nuanced recommendations for identifying individuals who may benefit the most from these interventions.

Tobacco use, trauma exposure and PTSD: a systematic review

Tobacco use remains one of the most significant preventable public health problems globally and is increasingly concentrated among vulnerable groups, including those with trauma exposure or diagnosed with PTSD. The goal of this systematic review was to update and extend previous reviews. Of the 7224 publications that met the initial criteria, 267 were included in the review. Summary topic areas include conceptual frameworks for the relation between trauma or PTSD and tobacco use; associations between trauma exposure or PTSD and tobacco use; number and type of trauma exposures and tobacco use; PTSD symptoms and tobacco use; Treatment-related studies; and the examination of causal relations. Evidence continues to indicate that individuals exposed to trauma or diagnosed with PTSD are more likely to use tobacco products, more nicotine dependent and less likely to abstain from tobacco even when provided evidence-based treatments than individuals without trauma. The most commonly cited causal association proposed was use of tobacco for self-regulation of negative affect associated with trauma. A small proportion of the studies addressed causality and mechanisms of action. Future work should incorporate methodological approaches and measures from which we can draw causal conclusions and mechanisms to support the development of viable therapeutic targets.

Pathophysiology in cortico-amygdala circuits and excessive aversion processing: the role of oligodendrocytes and myelination

Stress-related psychiatric illnesses, such as major depressive disorder, anxiety and post-traumatic stress disorder, present with alterations in emotional processing, including excessive processing of negative/aversive stimuli and events. The bidirectional human/primate brain circuit comprising anterior cingulate cortex and amygdala is of fundamental importance in processing emotional stimuli, and in rodents the medial prefrontal cortex-amygdala circuit is to some extent analogous in structure and function. Here, we assess the comparative evidence for: (i) Anterior cingulate/medial prefrontal cortex<->amygdala bidirectional neural circuits as major contributors to aversive stimulus processing; (ii) Structural and functional changes in anterior cingulate cortex<->amygdala circuit associated with excessive aversion processing in stress-related neuropsychiatric disorders, and in medial prefrontal cortex<->amygdala circuit in rodent models of chronic stress-induced increased aversion reactivity; and (iii) Altered status of oligodendrocytes and their oligodendrocyte lineage cells and myelination in anterior cingulate/medial prefrontal cortex<->amygdala circuits in stress-related neuropsychiatric disorders and stress models. The comparative evidence from humans and rodents is that their respective anterior cingulate/medial prefrontal cortex<->amygdala circuits are integral to adaptive aversion processing. However, at the sub-regional level, the anterior cingulate/medial prefrontal cortex structure-function analogy is incomplete, and differences as well as similarities need to be taken into account. Structure-function imaging studies demonstrate that these neural circuits are altered in both human stress-related neuropsychiatric disorders and rodent models of stress-induced increased aversion processing. In both cases, the changes include altered white matter integrity, albeit the current evidence indicates that this is decreased in humans and increased in rodent models. At the cellular-molecular level, in both humans and rodents, the current evidence is that stress disorders do present with changes in oligodendrocyte lineage, oligodendrocytes and/or myelin in these neural circuits, but these changes are often discordant between and even within species. Nonetheless, by integrating the current comparative evidence, this review provides a timely insight into this field and should function to inform future studies-human, monkey and rodent-to ascertain whether or not the oligodendrocyte lineage and myelination are causally involved in the pathophysiology of stress-related neuropsychiatric disorders.

Understanding the gaps in headache and migraine treatment with psychological and behavioral interventions: A narrative review

OBJECTIVE

In this narrative review, we summarize relevant literature pertaining to psychosocial risk factors for headache and migraine progression, current behavioral and psychological treatments, and consider promising treatments.

BACKGROUND

Headache and migraine are common and associated with significant burden and disability. Current treatments targeting psychosocial risk factors show modest outcomes and do not directly address the impact of early life adversity, including the development of maladaptive emotional processing. An intervention that could address these factors and include components of current evidence-based interventions may lead to improved outcomes.

METHODS

We searched PubMed and Google Scholar for articles through December 2022. Search terms included headache, migraine, psychological interventions, behavioral interventions, cognitive-behavioral therapy, mindfulness, psychiatric comorbidities, adverse childhood experiences, trauma, and emotional processing.

RESULTS

Trauma and childhood adversity show a correlation with headache and migraine progression. Developmental adversity and trauma interfere with adaptive emotional processing, which may worsen headache and migraine symptoms, while adaptive ways of experiencing emotions are shown to improve symptoms. Current behavioral and psychological interventions, such as cognitive-behavioral and mindfulness therapies, are effective treatments for headache, but they produce small to medium effect sizes and do not directly address the impact of trauma and emotional conflicts-common factors that contribute to chronicity and disability, especially among certain subpopulations of headache patients such as those with migraine. Thus, there exists a gap in current treatment.

CONCLUSION

There is a gap in headache and migraine treatment for those patients who have a history of trauma, childhood adversity, and maladaptive emotional processing. We suggest that an integrated psychological treatment that includes components of current evidence-based interventions and addresses gaps by focusing on processing trauma-related emotions may improve chronic and debilitating symptoms.

Circadian cortisol secretion in adolescent girls with conduct disorder

Severe antisocial behavior in girls, best exemplified by conduct disorder (CD), is a serious clinical and public health problem. Treatment is difficult, particularly in girls with comorbid internalizing disorders. Identifying biological correlates may help to develop new treatments or diagnostic, prognostic, or treatment response biomarkers. Based on our earlier work and research from others occurring primarily in boys with severe antisocial behavior, it is possible that abnormalities in the hypothalamic pituitary adrenal (HPA) axis circadian cortisol cycle may be associated with female CD. Additionally, research suggests that the presence of comorbid internalizing disorders may be related to differences in cortisol secretion, compared to subjects who only have CD. Our study aimed: 1) to compare the circadian cortisol cycle in 98 girls with CD, 15-16 years of age to 47 girls without any psychiatric disorder (ND) and 2) to compare the cycle in girls with CD and comorbid internalizing disorders (CD + INT) to those without such comorbidity (CD Only). Salivary cortisol was collected over 24 h during weekdays at scheduled times, with protocol adherence measures in place. Unstructured covariance pattern modeling, controlling for effects of age, social class, IQ, and awakening time was used to analyze cortisol data. CD was associated with overall lower cortisol secretion (p = 0.03), but this difference was due to a lower volume of cortisol secreted 30 min after awakening (area under the curve with respect to ground, p = 0.01). Circadian cortisol secretion was no different in the CD+INT group compared to the CD Only group (p = 0.52). Our findings need to be replicated using current consensus guidelines for the assessment of the CAR. We also suggest two new avenues of research in this field.

Peri-Traumatic Dissociation and Tonic Immobility as Severity Predictors of Posttraumatic Stress Disorder After Rape

Some individuals show abnormal reactions to extreme fear and life-threatening situations, including tonic immobility (TI) and peri-traumatic dissociation (PTD). We aimed to investigate the association of TI and PTD with posttraumatic stress disorder (PTSD) in women who experienced sexual violence and the risk factors for PTD occurrence. We compared PTSD severity in 86 young adult women with PTSD after a sexual violence exposure grouped according to the presence of PTD and TI. In addition, we investigated whether PTD is associated with depression and anxiety symptoms and assessed potential risk factors for PTD reaction. We found a significant positive correlation between PTSD severity and PTD occurrence (R² = .132; p = .001). PTD was also positively correlated with all clusters of PTSD symptoms except the Clinician-Administered PTSD Scale avoidance cluster (p = .058). PTD was strongly correlated with anxiety (R² = .619; p < .001) and depressive symptoms (R² = .547; p < .001). Multiple logistic regression showed that history of physical abuse (odds ratio [OR]: 1.386; p = .011) and sexual abuse (OR: 1.947; p = .004) during childhood were associated with PTD occurrence. Other risk factors for PTD were having less years of study (OR: 0.216; p = .016) and lower income (OR: 7.403; p = .028). TI measures were available for a subsample of 29 women. We found no association between TI and PTSD severity. PTD, but not TI, is significantly associated with more severe PTSD, depressive, and anxiety symptoms. Less-educated women with a history of childhood abuse and a lower income are at risk of PTD occurrence during a sexual violence episode.

Modeling integrated stress, sleep, fear and neuroimmune responses: Relevance for understanding trauma and stress-related disorders

Sleep and stress have complex interactions that are implicated in both physical diseases and psychiatric disorders. These interactions can be modulated by learning and memory, and involve additional interactions with the neuroimmune system. In this paper, we propose that stressful challenges induce integrated responses across multiple systems that can vary depending on situational variables in which the initial stress was experienced, and with the ability of the individual to cope with stress- and fear-inducing challenges. Differences in coping may involve differences in resilience and vulnerability and/or whether the stressful context allows adaptive learning and responses. We provide data demonstrating both common (corticosterone, SIH and fear behaviors) and distinguishing (sleep and neuroimmune) responses that are associated with an individual's ability to respond and relative resilience and vulnerability. We discuss neurocircuitry regulating integrated stress, sleep, neuroimmune and fear responses, and show that responses can be modulated at the neural level. Finally, we discuss factors that need to be considered in models of integrated stress responses and their relevance for understanding stress-related disorders in humans.

Effectiveness of treatments for symptoms of post-trauma related guilt, shame and anger in military and civilian populations: a systematic review

INTRODUCTION

Individuals who have been exposed to a traumatic event can develop profound feelings of guilt, shame and anger. Yet, studies of treatments for post-traumatic stress disorder (PTSD) have largely investigated changes in PTSD symptoms relating to a sense of ongoing fear or threat and the effectiveness of such treatments for post-trauma related guilt, shame or anger symptom reduction is comparatively not well understood.

METHODS

This review systematically examined the effectiveness of existing treatment approaches for three symptoms associated with exposure to traumatic events: guilt, shame and anger. Studies included had to be published after 2010 with a sample size of n=50 or greater to ensure stable treatment outcome estimates.

RESULTS

15 studies were included, consisting of both civilian and (ex-) military population samples exposed to a wide range of traumatic events (eg, combat-related, sexual abuse). Findings indicated a moderate strength of evidence that both cognitive-based and exposure-based treatments are similarly effective in reducing symptoms. Cognitive-based treatments were found to effectively reduce post-trauma related guilt and anger, while exposure-based treatments appeared effective for post-trauma related guilt, shame and anger.

CONCLUSIONS

The findings suggest the importance of confronting and discussing the traumatic event during therapy, rather than using less directive treatments (eg, supportive counselling).Nonetheless, while these results are promising, firm conclusions regarding the comparative effectiveness and long-term impact of these treatments could not be drawn due to insufficient evidence. Further empirical research is needed to examine populations exposed to traumatic events and investigate which treatment approaches (or combination thereof) are more effective in the long-term.

Psychological trauma as a transdiagnostic risk factor for mental disorder: an umbrella meta-analysis

This umbrella review is the first to systematically examine psychological trauma as a transdiagnostic risk factor across psychiatric conditions. We searched Pubmed, Scopus, and PsycNET databases from inception until 01/05/2021 for systematic reviews/meta-analyses evaluating the association between psychological trauma and at least one diagnosed mental disorder. We re-calculated the odds ratio (OR), then classified the association as convincing, highly suggestive, suggestive, or weak, based on the number of cases and controls with and without psychological trauma, random-effects p value, the 95% confidence interval of the largest study, heterogeneity between studies, 95% prediction interval, small-study effect, and excess significance bias. Additional outcomes were the association between specific trauma types and specific mental disorders, and a sensitivity analysis for childhood trauma. Transdiagnosticity was assessed using TRANSD criteria. The review was pre-registered in Prospero CRD42020157308 and followed PRISMA/MOOSE guidelines. Fourteen reviews met inclusion criteria, comprising 16,277 cases and 77,586 controls. Psychological trauma met TRANSD criteria as a transdiagnostic factor across different diagnostic criteria and spectra. There was highly suggestive evidence of an association between psychological trauma at any time-point and any mental disorder (OR = 2.92) and between childhood trauma and any mental disorder (OR = 2.90). Regarding specific trauma types, convincing evidence linked physical abuse (OR = 2.36) and highly suggestive evidence linked sexual abuse (OR = 3.47) with a range of mental disorders, and convincing evidence linked emotional abuse to anxiety disorders (OR = 3.05); there were no data for emotional abuse with other disorders. These findings highlight the importance of preventing early traumatic events and providing trauma-informed care in early intervention and psychiatric services.

Effects of chronic social stress on oligodendrocyte proliferation-maturation and myelin status in prefrontal cortex and amygdala in adult mice

Stress-related neuropsychiatric disorders present with excessive processing of aversive stimuli. Whilst underlying pathophysiology remains poorly understood, within- and between-regional changes in oligodendrocyte (OL)-myelination status in anterior cingulate cortex and amygdala (ACC-AMY network) could be important. In adult mice, a 15-day chronic social stress (CSS) protocol leads to increased aversion responsiveness, accompanied by increased resting-state functional connectivity between, and reduced oligodendrocyte- and myelin-related transcript expression within, medial prefrontal cortex and amygdala (mPFC-AMY network), the analog of the human ACC-AMY network. In the current study, young-adult male C57BL/6 mice underwent CSS or control handling (CON). To assess OL proliferation-maturation, mice received 5-ethynyl-2'-deoxyuridine via drinking water across CSS/CON and brains were collected on day 16 or 31. In mPFC, CSS decreased the density of proliferative OL precursor cells (OPCs) at days 16 and 31. CSS increased mPFC myelin basic protein (MBP) integrated density at day 31, as well as increasing myelin thickness as determined using transmission electron microscopy, at day 16. In AMY, CSS increased the densities of total CC1+ OLs (day 31) and CC1+/ASPA+ OLs (days 16 and 31), whilst decreasing the density of proliferative OPCs at days 16 and 31. CSS was without effect on AMY MBP content and myelin thickness, at days 16 and 31. Therefore, CSS impacts on the OL lineage in mPFC and AMY and to an extent that, in mPFC at least, leads to increased myelination. This increased myelination could contribute to the excessive aversion learning and memory that occur in CSS mice and, indeed, human stress-related neuropsychiatric disorders.

A clinical trial comparing trauma-informed guilt reduction therapy (TrIGR), a brief intervention for trauma-related guilt, to supportive care therapy

INTRODUCTION

Trauma-related guilt is common, associated with posttraumatic mental health problems, and can persist after posttraumatic stress disorder (PTSD) treatment. We compared the efficacy of two six-session psychotherapies, Trauma-Informed Guilt Reduction (TrIGR) and Supportive Care Therapy (SCT), for reducing trauma-related guilt. TrIGR helps patients accurately appraise their role in the trauma and re-engage in values. In SCT, patients guide session content.

METHODS

A total of 184 veterans seeking VA mental health services were enrolled across two sites; 145 veterans (mean age: 39.2 [8.1]; 92.4% male; 84.8% with PTSD) who endorsed guilt related to a traumatic event that occurred during a post 9/11 Iraq or Afghanistan deployment were randomized and assessed at baseline, posttreatment, 3- and 6-month follow-up.

RESULTS

Linear mixed models using intent-to-treat analyses showed guilt decreased in both conditions with a greater decrease for TrIGR (treatment × time, -0.22; F _{1, 455.2}  = 18.49, p = .001; d = 0.92) than supportive therapy. PTSD and depressive symptoms showed the same pattern. TrIGR had significantly higher likelihood of PTSD treatment response (67% vs. 40%), loss of PTSD diagnosis (50% vs. 14%), and meaningful change in depression (54% vs. 27%) than supportive therapy. Psychological distress and trait shame improved in both conditions. Quality of life did not change.

CONCLUSIONS

Targeting guilt appears to be an effective means for reducing posttraumatic symptoms and distress.

Common and specific large-scale brain changes in major depressive disorder, anxiety disorders, and chronic pain: a transdiagnostic multimodal meta-analysis of structural and functional MRI studies

Major depressive disorder (MDD), anxiety disorders (ANX), and chronic pain (CP) are closely-related disorders with both high degrees of comorbidity among them and shared risk factors. Considering this multi-level overlap, but also the distinct phenotypes of the disorders, we hypothesized both common and disorder-specific changes of large-scale brain systems, which mediate neural mechanisms and impaired behavioral traits, in MDD, ANX, and CP. To identify such common and disorder-specific brain changes, we conducted a transdiagnostic, multimodal meta-analysis of structural and functional MRI-studies investigating changes of gray matter volume (GMV) and intrinsic functional connectivity (iFC) of large-scale intrinsic brain networks across MDD, ANX, and CP. The study was preregistered at PROSPERO (CRD42019119709). 320 studies comprising 10,931 patients and 11,135 healthy controls were included. Across disorders, common changes focused on GMV-decrease in insular and medial-prefrontal cortices, located mainly within the so-called default-mode and salience networks. Disorder-specific changes comprised hyperconnectivity between default-mode and frontoparietal networks and hypoconnectivity between limbic and salience networks in MDD; limbic network hyperconnectivity and GMV-decrease in insular and medial-temporal cortices in ANX; and hypoconnectivity between salience and default-mode networks and GMV-increase in medial temporal lobes in CP. Common changes suggested a neural correlate for comorbidity and possibly shared neuro-behavioral chronification mechanisms. Disorder-specific changes might underlie distinct phenotypes and possibly additional disorder-specific mechanisms.

Time course of symptoms in posttraumatic stress disorder with delayed expression: A systematic review

OBJECTIVE

To examine the hypothesis that PTSD with delayed expression in some cases occurs without subthreshold PTSD symptoms above background levels bridging the gap between the traumatic exposure(s) and the clinical diagnosis.

METHODS

We performed systematic searches of peer-reviewed papers in English referenced in Pubmed, Embase, or PsycINFO and ascertained 34 prospective studies of PTSD symptom trajectories identified by latent class growth statistical modeling. Studies with delayed and low-stable trajectories provided appropriate data for this study. We computed the difference between the delayed trajectory PTSD symptom sumscore and the low-stable PTSD sumscore at the observed points in time after the traumatic event(s).

RESULTS

In 29 study populations, the latent class growth analyses displayed delayed trajectories, and in these, we identified 110 data points (% PTSD sumscore difference/months since traumatic exposure). The median PTSD symptom sumscore was 25% higher during the initial 6 months among individuals in the delayed trajectory compared to those in low-stable trajectory. From this level, the difference widened and reached a plateau of 40-50% higher. The variation was large, and the baseline participation rate and loss to follow-up were exceeding 25% in the majority of the studies. Heterogeneity of populations, measures, and analyses precluded formal meta-analysis.

CONCLUSION

Delayed PTSD is preceded by PTSD symptoms during the first year in most cases. Still, few individuals may experience an asymptomatic delay. The results underpin the rationale for monitoring PTSD symptoms and may inform forensic assessments in that delayed PTSD without symptoms bridging the traumatic event is rare.

A Possible Anti-anxiety Effect of Appetitive Aggression and a Possible Link to the Work of Donald Winnicott

Various pleasant sensations that give a particularly intense pleasure are able to improve anxiety. In the present study I consider the possibility that their anti-anxiety action depends on the strong pleasure they provide, and I propose a possible mechanism of this action. According to some studies, also appetitive aggression (an aggression that provokes a strong pleasure and that is performed only for the pleasure it provides) can improve anxiety, and in this article I consider the possibility that the pleasure of appetitive aggression is able to reduce anxiety by the same mechanism I have proposed for other intense pleasurable sensations. The aggression performed by a child against the mother or against a substitute for the mother in the first period of life (a period in which this aggression is not dangerous) is a recurring theme throughout the work of of Donald Winnicott. Winnicott stresses that this aggression is necessary for the normal development of the child, and that the child must be free to practise it. According to Winnicott, this aggression is highly pleasurable and is not a response to unpleasant or hostile external situations. For these characteristics it seems to correspond to appetitive aggression in the adult that has been found to be able to reduce anxiety. Consequently, aggression performed by the child in the first period of life may also relieve anxiety, in the same way that appetitive aggression helps against anxiety in the adult. In his writings, Winnicott returns several times to an unthinkable or archaic anxiety that children experience when they feel abandoned by their mother for a period that is too long for them, and all children, according to Winnicott, live on the brink of this anxiety. In this study I propose the hypothesis that aggression in the early period of life may be necessary for children because the intense pleasure it provides may help them against this continuously impending anxiety.

Children's daily lives and well-being: Findings from the CORONA-CODOMO survey 1st wave

BACKGROUND

The coronavirus disease 2019 pandemic has changed people's lives dramatically. Few data on the acute effects of the pandemic on children's daily lives and well-being have been published to date. This study aimed to capture its effects on Japanese children during the first peak of the outbreak.

METHODS

We conducted a web-based, anonymous cross-sectional survey targeting Japanese children aged 7-17 years and parents/guardians of children aged 0-17 years. Eligible individuals were invited to participate in the survey from April 30 to May 31, 2020. This self-report questionnaire examined daily life and behaviors, psychological symptoms, well-being, quality of life, and positive parenting or abusive behaviors at the very beginning of the outbreak.

RESULTS

A total of 2,591 children and 6,116 parents/guardians participated in our survey. Sixty-two percent of children reported screen time exceeding 2 h. Twenty percent of children reported abusive behaviors by family members. Nine in ten parents/guardians of school-aged children reported that their child had at least one acute stress symptom in the past month. Average mental health subscale scores from KINDL^R questionnaire on quality of life were lower than the national average for all grades. Nearly half of parents/guardians refrained from seeking medical care for the child's symptoms.

CONCLUSIONS

The COVID-19 pandemic had serious acute impacts on Japanese children's daily lives, well-being, family relationships, and health-care utilization, including some impacts that are potentially long-lasting; thus, proactive interventions and services are needed, as well as longitudinal surveys.

Maternal Deprivation Increased Vulnerability to Depression in Adult Rats Through DRD2 Promoter Methylation in the Ventral Tegmental Area

OBJECTIVE

Early life adversity is a risk factor for depression in adulthood; however, the underlying mechanisms are not well understood. This study aims to investigate the effect of DNA methylation of DRD2 gene on early life stress-induced depression in adult rats.

METHODS

Newborn Sprague-Dawley rats were randomly assigned to four groups: maternal deprivation group (MD), chronic unpredictable stress (CUS) group, maternal deprivation plus chronic unpredictable stress (MD/CUS) group, and normal control group (NOR). Behaviors were measured by open field test (OFT), sucrose preference test (SPT), and Original Research Article forced swimming test (FST). Fecal CORT level was detected by ELISA. Bisulfite amplicon sequencing PCR was used to assess methylation levels of DRD2 promoter.

RESULTS

CUS and MD/CUS rats had a significantly shorter total distance, longer immobility time, and higher CORT level, while MD and MD/CUS rats had a significantly lower percentage of central distance, more feces, lower rate of sucrose preference, and lower levels of DRD2 protein and mRNA in the VTA than NOR rats. CUS rats showed a significantly higher DRD2 mRNA and protein levels in the VTA than NOR rats. CUS, MD, and MD/CUS rats showed a significantly higher level of DRD2 promoter methylation than NOR rats. CORT level was significantly correlated with the sucrose preference rate in SPT, the immobility time in FST, the total distance, and the number of fecal pellets in OFT. DRD2 protein level was significantly correlated with the sucrose preference rate and the number of fecal pellets. DRD2 mRNA level was significantly correlated with the percentage of central distance and the number of fecal pellets in OFT. The level of DRD2 promoter methylation was significantly correlated with the sucrose preference rate, immobility time, total distance, the percentage of central distance, and the number of fecal pellets.

CONCLUSIONS

Early life MD increased vulnerability to stress-induced depressive-like behavior in adult rats. Enhanced DRD2 promoter methylation in the VTA may increase the susceptibility to depression.

The validity of the state-trait anxiety inventory and the brief scale for anxiety in an inpatient sample with alcohol use disorder

BACKGROUND AND AIMS

The Brief Scale for Anxiety (BSA) and the State-Trait Anxiety Inventory Form Y-2 (STAI-Y-2) are self-report scales used to gauge anxiety symptoms in clinical settings. Co-occuring anxiety is common in alcohol use disorder (AUD); however, no studies have assessed the validity of the BSA and STAI-Y-2 compared with a clinical diagnostic tool of anxiety in alcohol treatment programs. We aimed to examine the validity of the BSA and STAI-Y-2 to predict a clinical diagnosis of an anxiety disorder (via the Structured Clinical Interview for DSM [SCID]) in AUD patients.

DESIGN

Participants were administered the BSA (n = 1005) on day 2 and the STAI-Y-2 (n = 483) between days 2 and 10 of the detoxification program. SCID-based clinical diagnoses of AUD and anxiety were made approximately on day 10.

SETTING AND PARTICIPANTS

Individuals seeking treatment for AUD admitted to an inpatient unit at the National Institutes of Health (NIH) Clinical Center in Bethesda, MD, USA (n = 1010).

MEASUREMENTS

Inclusion criteria included a current diagnosis of alcohol dependence (AD) according to DSM-IV-TR or moderate to severe AUD according to DSM-5-RV, as well as available baseline BSA and/or STAI Y-2 data. Empirical receiver operating characteristic (ROC) curves were generated using estimates of sensitivity, 1-specificity and positive and negative predictive values for each cut-point to determine the accuracy of scale outcomes in relation to SCID diagnoses.

FINDINGS

The BSA demonstrated low accuracy relative to a clinical diagnosis of anxiety with an area under the curve (AUC) of 0.67 at the optimal cut-point of ≥ 10. The STAI-Y-2 had moderate accuracy relative to a clinical diagnosis of anxiety with an AUC of 0.70 at the optimal cut-point of ≥ 51. The accuracy of the STAI-Y-2 increased (AUC = 0.74) when excluding post-traumatic stress disorder and obsessive-compulsive disorder from anxiety disorder classification.

CONCLUSIONS

Use of the Brief Scale for Anxiety (BSA) and/or State-Trait Anxiety Inventory Form Y-2 (STAI-Y-2) does not appear to be a reliable substitute for clinical diagnoses of anxiety disorder among inpatients with alcohol use disorder. The BSA and STAI-Y-2 could serve as a screening tool to reject the presence of anxiety disorders rather than for detecting an anxiety disorder.

Longitudinal study indicating antecedent psychosocial vulnerability as predictor of anxiety disorders post-treatment in people with head and neck cancer

OBJECTIVE

This study aimed to: (1) determine the contribution of pre-cancer psychosocial vulnerability as an independent predictor of anxiety disorder (AD) onset immediately post-treatment in patients diagnosed with a first occurrence of head and neck cancer (HNC), controlling for sociodemographics and medical variables; and (2) estimate prevalence of AD and identify trajectories from the moment of diagnosis to the immediate post-treatment (i.e., over a period of 3 months) in this population.

METHODS

Two-hundred twenty-four consecutive patients (participation rate = 72%) newly diagnosed with a primary HNC were assessed with a structured clinical interview for a mental disorder, validated psychometric measures, and medical chart reviews.

RESULTS

Twenty-five percent of patients presented a lifetime AD, 19.4% within 2 weeks of HNC diagnosis, and 16.6% immediately post-treatment; representing 26.7% of patients with AD at any timepoint from the moment of diagnosis to immediately post-treatment. Patients were more likely to present an AD immediately post-treatment when they: were diagnosed with advanced-stage cancer (OR = 3.40, p = 0.006), presented a upon cancer diagnosis AD (OR = 2.45, p = 0.008) and/or experienced childhood abuse (OR = 1.96, p = 0.03).

CONCLUSIONS

Several AD trajectories may arise when patients are diagnosed with primary HNC. Health professionals should address AD and screen for risk factors (i.e., advanced stage cancer, AD upon cancer diagnosis, history of childhood abuse) as early as possible to assure optimal mental health care in this vulnerable population.

The path to dissociative experiences: A direct comparison of different etiological models

Severe dissociation is trauma-related, but a range of dissociative experiences are also prevalent in clinical populations that are not necessarily trauma-based (e.g., depression, anxiety disorders, and obsessive-compulsive disorders). These remain poorly understood as the dominant etiological model for dissociation relies on trauma. Importantly, dissociation in such samples predicts poor prognosis and high drop-out rates. We set out to better understand the aetiology of dissociative experiences in a mixed clinical (anxiety and depression) and community sample by exploring between- and within-subjects effects of two domains: psychological distress or negative affectivity (operationalized as anxiety and depression symptoms), and poor sleep quality, including disturbed dreaming. The idea that negative affectivity triggers dissociation (Distress Model) is inspired by the trauma model. The idea that poor sleep and unusual dreaming underlie dissociation (Sleep Model) has been suggested as a competing theory. We examined both models by exploring which domains oscillate alongside dissociative experiences. N = 98 adults, half of them diagnosed with depression and anxiety and half community controls, underwent a structured clinical interview and completed questionnaires monthly for 6 months. Support was found for both models in that each domain had a unique explanatory contribution. Distress evinced consistent effects that could not be explained by sleep or dreaming, both between individuals and across time. Oscillations in dissociation across months, when taking psychological distress into account, were better explained by unusual dreaming than traditional sleep quality measures. These findings cannot be generalized to highly-traumatized samples. A complex, integrated etiological model for dissociative experiences is warranted.

Posttraumatic Stress Disorder and Neuroprogression in Women Following Sexual Assault: Protocol for a Randomized Clinical Trial Evaluating Allostatic Load and Aging Process Acceleration

BACKGROUND

Posttraumatic stress disorder (PTSD) is a prevalent, chronic, and severe disorder related to traumatic events. Women are disproportionately affected by PTSD than men and are more at risk in the occurrence of sexual assault victimization. Estimates suggest that 50% of women develop PTSD following sexual assault and successful clinical management can be challenging. Growing evidence has implicated neural, immune, and endocrine alterations underpinning PTSD, but only few studies have assessed the evolution of acute PTSD in women.

OBJECTIVE

This study aims to measure whether the onset of PTSD is associated with accelerated aging in women following sexual assault. We hypothesize that the increase of allostatic load caused by PTSD leads to neuroprogression. We will implement a randomized clinical trial to compare responses to treatment with either interpersonal psychotherapy adapted for PTSD (IPT-PTSD) or the selective serotonin reuptake inhibitor sertraline.

METHODS

We will include women between 18 and 45 years of age, who experienced sexual assault from 1 to 6 months before the initial evaluation, and present with a Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) diagnosis of PTSD. Baseline evaluation will comprise clinical and psychometric assessments, structural and functional magnetic resonance imaging, neuropsychological testing, polysomnography, evaluation of immune and endocrine parameters, and genetic analyses. Age-matched female healthy controls will be included and subjected to the same evaluation. Patients will be randomized for treatment in 1 of the 2 arms of the study for 14 weeks; follow-up will continue until 1 year after inclusion via treatment as usual. The researchers will collect clinical and laboratory data during periodic clinical assessments up to 1-year follow-up.

RESULTS

Data collection started in early 2016 and will be completed by the end of the first semester of 2020. Analyses will be performed soon afterward, followed by the elaboration of several articles.

CONCLUSIONS

We expect to provide insight into the consequences of recent sexual assault exposure in women by investigating the degree of neuroprogression developing from an early stage of PTSD. We also expect to provide important evidence on the efficacy of a non-exposure psychotherapy (IPT-PTSD) to mitigate PTSD symptoms in recently sexually assaulted women. Further, we aim to obtain evidence on how treatment outcomes are associated with neuroprogression measures.

Occupational and non-occupational injuries can result in prolonged augmentation of psychiatric disorders

Background

The long-term effects of occupational injury (OI) on psychiatric diseases are unclear. This study assessed and compared the effects of OI, no injury (control), and non-OI (NOI) on the development of psychiatric diseases.

Methods

We used Taiwan’s National Health Insurance Research Database to investigate the incidence of psychiatric disorders in OI, NOI, and control groups. The subjects were aged 20–50 years, actively employed in 2000, and did not have history of injury or psychiatric disorders. All subjects were followed from 2000 and were classified into OI, NOI, and control groups according to occurrence of target injury later on. Individuals in each group were matched by age, sex, insurance premium before the index date, and year of the index date. Psychiatric disease-free days were compared among the groups using survival analysis and Cox regression.

Results

We included a total of 12,528 patients for final analysis, with 4,176 in each group. Compared with the control group, the OI group had an increased occurrence of trauma and stress-related disorder, depressive disorders, anxiety disorders, and alcohol and other substance dependence. These increases were similar to those in the NOI group. Elevated cumulative incidence rate of any psychiatric disorders was observed among those with OI or NOI up to 10 years after injury.

Conclusion

We confirmed that OI and NOI induced psychiatric disorders. These findings highlight the need for workers’ compensation mechanisms to consider long-term psychological care among injured workers.

Psychospiritual Developmental Risk Factors for Moral Injury

There is increasing theoretical, clinical, and empirical support for the hypothesis that psychospiritual development, and more specifically, postconventional religious reasoning, may be related to moral injury. In this study, we assessed the contributions of exposure to potentially morally injurious events, posttraumatic stress symptoms, and psychospiritual development to moral injury symptoms in a sample of military veterans (N = 212). Psychospiritual development was measured as four dimensions, based on Wulff’s theory juxtaposing conventional vs. postconventional levels of religious reasoning, with decisions to be an adherent or a disaffiliate of faith. After controlling for exposure to potentially morally injurious events and severity of posttraumatic stress symptoms, veterans who were conventional disaffiliates reported higher scores on the Moral Injury Questionnaire than conventional adherents, postconventional adherents, or postconventional disaffiliates. We conclude that the role of psychospiritual development offers a theoretical approach to moral injury that invites collaboration between social scientists, philosophers, theologians, and medical professionals.

A multi-method assessment of interoception among sexual trauma survivors

It is well established that many female sexual trauma survivors experience dissociation, particularly disconnection from the body, in the aftermath of sexual trauma. This study aims to address the open question of how sexual trauma is associated with awareness of inner body sensations (i.e., interoception). Given the important role that interoception has in emotion regulation, a process with which survivors often struggle, it is important to understand the associations between interoception and PTSD symptoms among survivors. Through multi-methods, we assessed associations between interoception, dissociation, and PTSD symptoms among 200 female sexual trauma survivors. We assessed two components of interoception: interoceptive accuracy (IAc: accurately perceiving internal body sensations; via heartbeat perception task) and interoceptive sensibility (IS: self-report perception of sensitivity to interoceptive sensations). We hypothesized that IAc and IS would be positively correlated with PTSD, with interactions between IAc/dissociation and IS/dissociation qualifying those main effects, weakening them for survivors with higher dissociation. Results showed an opposite pattern than was predicted: although IAc did explain significant PTSD variance, as IAc increased, PTSD decreased. Although IAc did explain significant variance in PTSD symptoms, interestingly, IS did not. Consistent with extant literature, dissociation predicted significant variance in PTSD. These correlational results suggest that the ability to more accurately perceive inner body sensations is related to lower PTSD symptoms. Findings provide a foundation for future research that can assess if interventions (such as yoga or exercise) that target increasing interoceptive accuracy lead to decreases in PTSD symptoms. We discuss further clinical implications, limitations and future directions.

Same same but different? DSM-5 versus ICD-11 PTSD among traumatized refugees in Germany

OBJECTIVE

The recent changes in diagnostic criteria for posttraumatic stress disorder (PTSD) in the 5th edition of the DSM and the 11th edition of the ICD marked a shift towards two perspectives on the same disorder. Previous studies indicate lower prevalence rates for the ICD-11-model as compared to the DSM-5 model. Main purpose of this study is to examine the concordance between ICD-11 and DSM-5 PTSD rates, and to assess the overlap of the two PTSD definitions with anxiety and depression among refugees.

METHODS

167 traumatized refugees were assessed with the PCL-5 for the DSM-5 PTSD model. A subset of the items was used as criteria for the ICD-11 model. Depression and anxiety were measured with the HSCL-25.

RESULTS

The DSM-5-algorithm for PTSD identified significantly more cases (n = 147; 88%) than the ICD-11 algorithm (80%; n = 134). Level of agreement between the diagnostic systems was substantial (Κ = 0.67, p < .001) and 9% (n = 15) met criteria under one diagnostic system only. Overlap with depression and anxiety was high under both diagnostic systems.

CONCLUSION

PTSD rates indicated a highly distressed sample of survivors of war and trauma. Our data provide further evidence that the DSM-5 diagnoses a larger number of persons than the ICD-11. Although the level of agreement was substantial, the observed discrepancies represent a challenge for research and practice to reliably identify individuals with PTSD. Especially for refugees, this might affect their access to mental health care and appropriate treatment during an asylum procedure.

Maternal prenatal depression, PTSD, and problematic parenting: the mediating role of maternal perceptions of infant emotion

Background: Perinatal illness is alarmingly common and has negative effects on maternal and infant well-being. Depression and posttraumatic stress disorder (PTSD), specifically, are characterised by negative views of the self and others, which may impact a mother's perceptions of herself and her child. Objective: This study examined the relationship between depression and PTSD symptoms, maternal perceptions of infant emotions, and parenting behaviours. Methods: 120 pregnant, mostly low-income women and their infants (after birth) participated in a longitudinal study. Maternal depression and PTSD symptoms were assessed during pregnancy and 1 year postpartum; maternal perceptions of infant emotions and parenting quality were assessed at 1 year. Results: Correlation analyses revealed significant, negative associations between prenatal (but not postnatal) psychiatric symptoms and positive perceptions of infant emotions, as well as between positive perceptions of infant emotions and negative parenting. Results also revealed significant indirect effects of prenatal depressive and PTSD symptoms on negative parenting via perceptions of infant emotion (95% CIs:.0013 -.0200 and.0008 -.0083, respectively). Conclusion: Findings highlight that mothers should be routinely screened for psychiatric symptoms during the perinatal period, and perceptions of infant emotions may be an important target for parent-infant mental health interventions.

Characterization of substance use among underrepresented sexual and gender minority participants in The Population Research in Identity and Disparities for Equality (PRIDE) Study

BACKGROUND

Profiles of substance use among less commonly described subgroups of sexual and gender minority (SGM) people (e.g., queer, genderqueer) remain largely unknown. Objective(s): To identify substance use differences among less commonly described SGM identity-based subgroups. Methods: The PRIDE Study is a national, online, longitudinal cohort study of self-identified SGM adults living in the U.S. Between 2015-2017, an iPhone application was used to administer three cross-sectional health questionnaires to participants, one of which included questions about binge alcohol, marijuana, and other drug use (substance use). This study was a secondary data analysis of participant responses to substance use survey items. Logistic regression and generalized linear modeling assessed relationships between sexual orientation or gender and use of or reported problems with substances within the past year. Results: Among the 1790 participants included in this study, 51.0% reported binge alcohol use, 39.8% reported marijuana use, and 19.7% reported other drug use (65.9% endorsed use of one or more of these) within the past year. Over 30% indicated substance use had been a problem in their life. Asexual individuals had lower odds of reporting past year binge alcohol and marijuana use (aOR: 0.27, 95% CI: 0.12-0.61; aOR: 0.38, 95% CI: 0.15-0.96, respectively), and queer participants had higher odds of reporting past year marijuana use (aOR: 2.52, 95% CI: 1.58-4.03) compared to lesbian participants. Gender nonbinary participants had lower odds of reporting past year binge alcohol use (aOR: 0.48, 95% CI: 0.32-0.71) and transmasculine participants had higher odds of reporting past year marijuana use (aOR: 2.18, 95% CI: 1.10-4.31) compared to cisgender women. Conclusions: Substance use heterogeneity exists between SGM groups. Comprehensive assessment of sexual orientation and gender may improve understanding of substance use and increase equity within support and treatment services for SGM populations. Highlights We examined substance use among less represented sexual and gender minority groups. Alcohol and other drug use were examined by both sexual orientation and gender identity. Analyses included identities such as queer, pansexual, genderqueer and nonbinary. Alcohol use differed across asexual, genderqueer and gender nonbinary groups. Marijuana use differed across queer, asexual and transmasculine groups.

Examining the boundaries between ICD-11 PTSD/CPTSD and depression and anxiety symptoms: A network analysis perspective

BACKGROUND

Two newly identified sibling disorders - ICD-11 PTSD and CPTSD - have been well validated in the last few years. Although these trauma-related disorders are suggested to be neatly separated from depression and anxiety, no study has used a network analysis to examine those definitions' construct validity when they also interplay with symptoms of depression and anxiety. Additionally, no research has focused upon the specific boundaries between these four disorders' symptoms, the bridges between them, and the ways they influence each other among clinical populations.

METHODS

A sample of 234 men drawn randomly from a national sample of 1,600 Jewish men receiving treatment for domestic violence in Israel completed the ICD-11 International Trauma Questionnaire (ITQ) and Brief Symptom Inventory (BSI).

RESULTS

The ICD-11 CPTSD, depression and anxiety clustering network results revealed, within the EGA, a four-cluster solution in which PTSD and CPTSD symptoms are differentiated from two other distinct clusters of anxiety and depression symptoms. Feelings of worthlessness and avoiding internal reminders of the experience were the most central symptoms.

LIMITATIONS

Due to the use of a cross-sectional design, causal interpretation of the network correlation between symptoms should be made cautiously.

CONCLUSIONS

These findings strengthen the approach that ICD-11 PTSD and CPTSD have a distinct construct; however, they also reflect a strong positive connection to anxiety and depression symptoms and no clear boundaries between disorders. Specifically, dysphoria/avoidance-related symptoms act as a bridge between the disorders, which may be important targets for specific assessments and related interventions.

Mental Health Symptoms in Patients With Familial Adenomatous Polyposis: An Observational Study

BACKGROUND

Almost all patients with familial adenomatous polyposis undergo abdominal surgery with a risk of disease and surgery-related complications. This, the familial nature of the syndrome, and its wide-ranging manifestations make patients prone to mental health symptoms. If this is true, patients need appropriate evaluation and treatment.

OBJECTIVE

The purpose of this study was to record the experience of mental health symptoms in a group of unselected patients with FAP.

DESIGN

We conducted an observational study using an anonymized mental health symptom survey for patients affected with familial adenomatous polyposis.

SETTINGS

The study was conducted using the Hereditary Colorectal Cancer Registry in a tertiary referral center.

PATIENTS

Patients affected with familial adenomatous polyposis were included.

MAIN OUTCOME MEASURES

Results of the mental health survey were measured.

RESULTS

Seventy nine of 100 patients completed the survey; 57 endorsed ≥1 psychosocial symptom (72.2%). with a mean of 4 per patient. Nine patients (11.4%) met all 4 of the American Psychiatric Association diagnostic criteria for posttraumatic stress disorder, and 8 (10.1%) endorsed partial posttraumatic stress disorder criteria (3/4 symptoms). Patients who met all of the criteria for posttraumatic stress disorder had an average of 9.3 psychosocial symptoms each compared with 8.3 for those who met 3 of 4 and 2.2 for those who met <3. Six patients endorsed suicidal thoughts, all of whom met 3 or 4 of the criteria for posttraumatic stress disorder.

LIMITATIONS

The study was limited by its referral bias toward severe cases and relatively small number of patients. Because of the limitations of an anonymous self-administered screening, no mental health diagnoses have been given.

CONCLUSIONS

Patients with familial adenomatous polyposis are at risk for mental health symptoms, which can be multiple and severe. Some patients need professional counseling. A correlation between familial adenomatous polyposis patients with posttraumatic stress disorder and suicidal ideation is important. See Video Abstract at http://links.lww.com/DCR/A995.

Is silence about trauma harmful for children? Transgenerational communication in Palestinian families

Style of family communication is considered important in the transgenerational transmission of trauma. This study had three aims: first, to identify the contents of family communication about past national trauma; second, to examine how parents' current war trauma is associated with transgenerational communication; and third, to analyze the associations between transgenerational communication and children's mental health, measured as posttraumatic stress disorder (PTSD), depression and psychological distress. The study sample consisted of 170 Palestinian families in Gaza Strip, in which both mothers (n = 170) and fathers (n = 170) participated, each with their 11-13-year-old child. Mothers and fathers responded separately to three questions: 1) what did their own parents tell them about the War of 1948, Nakba?; 2) what did they tell their own children about the Nakba?; and 3) What did they tell their own children about the 1967 Arab-Israeli War and military occupation? Current war trauma, as reported separately by mothers, fathers and their children, refers to the Gaza War 2008/09. Children reported their symptoms of PTSD, depression, and psychological distress. Results revealed seven communication content categories and one category indicating maintaining silence about the traumas. Fathers' high exposure to current war trauma was associated with a higher level of communicating facts, reasons, and meanings regarding the1948 and 1967 wars, and mothers' high exposure to current war trauma was associated with a lower level of maintaining silence. Family communication about facts, reasons, and meanings was significantly associated with children not showing PTSD and marginally with not showing psychological distress, while maintaining silence was not associated with children's mental health.

PTSD symptoms are differentially associated with general distress and physiological arousal: Implications for the conceptualization and measurement of PTSD

BACKGROUND

The primary purpose of this study was to examine the place of posttraumatic stress disorder (PTSD) vis-à-vis the external dimensions of general distress and physiological arousal.

METHODS

Using data collected from veterans of the wars in Iraq and Afghanistan (N = 1350), latent variable covariance structure modeling was employed to compare correlations of PTSD symptom clusters and individual PTSD symptoms with general distress and physiological arousal.

RESULTS

Each PTSD symptom cluster, and 17 of 20 individual PTSD symptoms were more strongly associated with general distress than with physiological arousal. However, moderate to strong associations were also found between physiological arousal and both PTSD clusters and symptoms.

LIMITATIONS

Findings are based on self-reported data elicited from a single sample of veterans with substantial PTSD symptoms. Replication, particularly by clinician interview, is necessary. Generalizability to other traumatized populations is unknown.

CONCLUSIONS

Results offer support, with caveats, for viewing PTSD as a distress disorder. Findings are not consistent with the position that PTSD is a hybrid disorder with some features reflecting hyperarousal and others indicative of general distress. Results have implications for the conceptualization and measurement of PTSD.

Psychiatric stressor recognition from clinical notes to reveal association with suicide

Suicide takes the lives of nearly a million people each year and it is a tremendous economic burden globally. One important type of suicide risk factor is psychiatric stress. Prior studies mainly use survey data to investigate the association between suicide and stressors. Very few studies have investigated stressor data in electronic health records, mostly due to the data being recorded in narrative text. This study takes the initiative to automatically extract and classify psychiatric stressors from clinical text using natural language processing-based methods. Suicidal behaviors were also identified by keywords. Then, a statistical association analysis between suicide ideations/attempts and stressors extracted from a clinical corpus is conducted. Experimental results show that our natural language processing method could recognize stressor entities with an F-measure of 89.01 percent. Mentions of suicidal behaviors were identified with an F-measure of 97.3 percent. The top three significant stressors associated with suicide are health, pressure, and death, which are similar to previous studies. This study demonstrates the feasibility of using natural language processing approaches to unlock information from psychiatric notes in electronic health record, to facilitate large-scale studies about associations between suicide and psychiatric stressors.

Sources of moral injury among war veterans: A qualitative evaluation

OBJECTIVE

Service members deployed to war are at risk for moral injury, but the potential sources of moral injury are poorly understood. The aim of this qualitative study was to explore the types of events that veterans perceive as morally injurious and to use those events to develop a categorization scheme for combat-related morally injurious events.

METHOD

Six focus groups with US war veterans were conducted.

RESULTS

Analysis based on Grounded Theory yielded two categories (and eight subcategories) of events that putatively cause moral injury. The two categories were defined by the focal attribution of responsibility for the event: Personal Responsibility (veteran's reported distress is related to his own behavior) versus Responsibility of Others (veteran's distress is related to actions taken by others). Examples of each type of morally injurious event are provided.

CONCLUSIONS

Implications for the further development of the moral injury construct and treatment are discussed.

From child maltreatment to ICD-11 complex post-traumatic stress symptoms: The role of emotion regulation and re-victimisation

OBJECTIVE

Complex post-traumatic stress disorder (CPTSD) will be introduced in ICD-11 and comprises symptoms of PTSD and disturbances in self-organisation (DSO). The association of trauma with PTSD and DSO is not yet fully understood. We investigated the path from child maltreatment to PTSD and DSO and examined the mediating role of emotion regulation (ER) and adult interpersonal re-victimisation.

METHOD

Adult patients (N = 193) from a Scottish National Health Service clinic participated in the project. Participants completed measures of life events, ICD-11 PTSD and CPTSD, and ER. Path analysis was used to assess possible direct and indirect effects from childhood trauma on current post-traumatic psychopathology.

RESULTS

Overall results indicate that the path from child maltreatment to PTSD is a direct one, while the path to DSO is indirectly mediated by ER.

CONCLUSIONS

Future research should address the potentially beneficial effect of treatment protocols for CPTSD explicitly aiming at reducing ER difficulties.

Clinical and functional outcomes of cannabis use among individuals with anxiety disorders: A 3-year population-based longitudinal study

BACKGROUND

Cannabis use has been reported to negatively affect the course and outcome of various psychiatric disorders, yet little is known on its effect on rates of remission from anxiety disorders and associated clinical and functional outcomes.

METHODS

In this study, data were drawn from Waves 1 and 2 of the National Epidemiologic survey on Alcohol and Related Conditions, focusing on individuals who qualified for a diagnosis of any anxiety disorder (social anxiety, panic disorder, generalized anxiety disorder, and specific phobias) at Wave 1 (N = 3,723). Cannabis users and individuals with cannabis use disorders (CUDs) throughout a 4-year period were compared to nonusers in rates of remission, suicidality, general functioning, and quality of life at Wave 2, while controlling for baseline confounders.

RESULTS

Although rates of remission decreased with level of cannabis use, this was not maintained in adjusted models. Aside from specific outcomes (individuals with CUDs were significantly more prone to report breaking up from a romantic relationship; adjusted odds ratio [AOR] = 3.85, 95% confidence interval [CI] = 1.66-8.97) and repeatedly quitting school (AOR = 6.02, 95% CI = 2.65-13.66)), following adjustment no additional differences were found in outcome measures.

CONCLUSIONS

These findings add to previous reports suggesting that poorer outcome of anxiety disorders among cannabis users may be attributed mainly to differences in baseline factors and not cannabis use.

Construct validation of the hybrid model of posttraumatic stress disorder: Distinctiveness of the new symptom clusters

Despite the factor analytic support for the seven-factor hybrid model (Armour et al., 2015) of posttraumatic stress disorder (PTSD), little research has examined the degree to which newly established symptom clusters (i.e., negative affect, anhedonia, dysphoric arousal, anxious arousal, externalizing behavior) functionally and meaningfully differ in their associations with other clinical phenomena. The aim of the current study was to examine the degree to which newly established PTSD symptom clusters differentially relate to co-occurring psychopathology and related clinical phenomena through Wald testing using latent variable modeling. Participants were 535 trauma-exposed undergraduates who completed the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5; Weathers et al., 2013) and Personality Assessment Inventory (PAI; Morey, 1991). As expected and in line with results from previous studies, significant heterogeneity emerged for dysphoric arousal, anxious arousal, and externalizing behavior. However, there was less evidence for the distinctiveness of negative affect and anhedonia. Results indicate that only some of the newly established symptom clusters significantly differ in their associations with related clinical phenomena and that the hybrid model might not provide a meaningful framework for understanding which PTSD symptoms relate to associated features. Limitations include a non-clinical sample and reliance on retrospective self-report assessment measures.

Adjustment disorder: A diagnosis whose time has come

BACKGROUND

Adjustment disorder is among the most frequently diagnosed mental disorders in clinical practice although it has received little academic attention and been the subject of substantial criticism over the past decades. While those suffering with adjustment disorders are often treated by mental health professionals, research interest in the origin of the disorder or the effectiveness of psychotherapeutic and medical interventions has only recently begun to emerge. This article summarizes the empirical literature published on adjustment disorder and points out current diagnostic developments in DSM-5 and ICD-11.

METHODS

Literature for this review was identified through established online search tools, including publications in English, German, and Spanish.

RESULTS

This paper reviews literature on the evolution of adjustment disorder, and highlights the current state of research with regard to genesis and treatment. Importantly, for the first time ICD-11 intends to define adjustment disorder by explicit symptom groups, unlike DSM-5.

LIMITATIONS

Publications without an English abstract were not included.

CONCLUSIONS

Key directions for future research include investigating the concordance of the ICD-11 and DSM-5 concepts and the effect that the diverging conceptualizations may have. Risk and protective factors specific to AD should be identified and the biological underpinnings of the disorder should be explored. Finally, given the high prevalence of AD in certain clinical settings effective disorder-specific interventions should be developed and evaluated.

Oxytocin-Oxytocin Receptor Systems Facilitate Social Defeat Posture in Male Mice

Social stress has deteriorating effects on various psychiatric diseases. In animal models, exposure to socially dominant conspecifics (i.e., social defeat stress) evokes a species-specific defeat posture via unknown mechanisms. Oxytocin neurons have been shown to be activated by stressful stimuli and to have prosocial and anxiolytic actions. The roles of oxytocin during social defeat stress remain unclear. Expression of c-Fos, a marker of neuronal activation, in oxytocin neurons and in oxytocin receptor‒expressing neurons was investigated in mice. The projection of oxytocin neurons was examined with an anterograde viral tracer, which induces selective expression of membrane-targeted palmitoylated green fluorescent protein in oxytocin neurons. Defensive behaviors during double exposure to social defeat stress in oxytocin receptor‒deficient mice were analyzed. After social defeat stress, expression of c-Fos protein was increased in oxytocin neurons of the bed nucleus of the stria terminalis, supraoptic nucleus, and paraventricular hypothalamic nucleus. Expression of c-Fos protein was also increased in oxytocin receptor‒expressing neurons of brain regions, including the ventrolateral part of the ventromedial hypothalamus and ventrolateral periaqueductal gray. Projecting fibers from paraventricular hypothalamic oxytocin neurons were found in the ventrolateral part of the ventromedial hypothalamus and in the ventrolateral periaqueductal gray. Oxytocin receptor‒deficient mice showed reduced defeat posture during the second social defeat stress. These findings suggest that social defeat stress activates oxytocin-oxytocin receptor systems, and the findings are consistent with the view that activation of the oxytocin receptor in brain regions, including the ventrolateral part of the ventromedial hypothalamus and the ventrolateral periaqueductal gray, facilitates social defeat posture.

Cotinine: A Therapy for Memory Extinction in Post-traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is a mental disorder that may develop after exposure to exceptionally threatening or unescapable horrifying events. Actual therapies fail to alleviate the emotional suffering and cognitive impairment associated with this disorder, mostly because they are ineffective in treating the failure to extinguish trauma memories in a great percentage of those affected. In this review, current behavioral, cellular, and molecular evidence supporting the use of cotinine for treating PTSD are reviewed. The role of the positive modulation by cotinine of the nicotinic acetylcholine receptors (nAChRs) and their downstream effectors, the protection of astroglia, and the inhibition of microglia in the PTSD brain are also discussed.

Measuring the ICD-11 adjustment disorder concept: Validity and sensitivity to change of the Adjustment Disorder - New Module questionnaire in a clinical intervention study

Adjustment disorder (AjD) is a frequent but under-researched diagnosis due in part to a lack of specific symptom criteria and adequate tools of measurement. The ICD-11 for the first time proposes a positive symptom catalogue to define AjD. This study presents a validation of the Adjustment Disorder - New Module (ADNM), the first symptom severity measure for AjD according to the ICD-11 concept. Validity and sensitivity to change were investigated in a sample of 190 individuals with a DSM-IV diagnosis of AjD. The ADNM scales demonstrated convergent and discriminant validity for anxiety symptoms (Hamilton Anxiety Scale; psychic anxiety r = 0.18-0.31), functional impairment (Sheehan Disability Scale; r = 0.18-0.47), and depression (Montgomery-Asberg Depression Scale; r = 0.13-0.30). At baseline 78% of the individuals with a DSM-IV diagnosis of AjD were also classified so by the ADNM. Repeated-measures ANOVA indicated significant ADNM-symptom decrease during treatment, replicating the patterns of the Hamilton Anxiety Scale, Sheehan Disability Scale, and Clinical Global Impression Scale. This article presents the first use of the ADNM as a measure for ICD-11 AjD in a randomized-controlled intervention study of AjD. It provides support for the construct validity and sensitivity to symptom change of this scale during pharmacological treatment.

DSM-5-based latent PTSD models: Assessing structural relations with GAD in Filipino post-relocatees

An increasing number of studies investigated the latent factor structure of posttraumatic stress disorder (PTSD) symptomatology following the new fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). To date, there is no consensus on the best representation of PTSD. This study examined six latent PTSD models in a sample of Filipino post-disaster relocatees (N = 523). Further investigation on the relationship of the best-fitting model to generalized anxiety disorder (GAD) in the latent level was conducted. The seven-factor hybrid model consisting of intrusion, avoidance, negative affect, anhedonia, externalizing behaviors, anxious arousal, and dysphoric arousal, was the best fitting model. Latent associations between the factors in the hybrid model and GAD suggest there are core and transdiagnostic features of PTSD. These findings have implications for understanding the underlying mechanism of PTSD and can inform the development of trauma-related interventions, particularly among post-disaster relocatees.

The Youth Anxiety Measure for DSM-5 (YAM-5): Correlations with anxiety, fear, and depression scales in non-clinical children

The Youth Anxiety Measure for DSM-5 (YAM-5) is a newly developed rating scale for assessing anxiety disorder symptoms of children and adolescents in terms of the contemporary classification system. In the present study, 187 children aged 8-12 years completed the new measure as well as the trait version of the State-Trait Anxiety Inventory for Children (STAIC), the Short Form of the Fear Survey Schedule for Children-Revised (FSSC-R-SF), the Spence Children's Anxiety Scale (SCAS), the Selective Mutism Questionnaire (SMQ), and the Children's Depression Inventory (CDI). Results indicated that part one of the YAM-5, which measures symptoms of the major anxiety disorders, was most substantially linked with the trait anxiety scale of the STAIC, whereas part two, which measures phobic symptoms, was most clearly associated with the FSSC-R-SF. The correlation between the YAM-5 and the SCAS was also robust, and particularly strong correlations were found between subscales of both questionnaires that assessed similar symptoms. Further, the selective mutism subscale of the YAM-5 was most clearly linked to the SMQ. Finally, the YAM-5 was also significantly correlated with depression symptoms as indexed by the CDI. These findings provide further support for the concurrent validity of the YAM-5.

A comparison of structural connectivity in anxious depression versus non-anxious depression

BACKGROUND

Major depressive disorder (MDD) and anxiety disorders are highly co-morbid. Research has shown conflicting evidence for white matter alteration and amygdala volume reduction in mood and anxiety disorders. To date, no studies have examined differences in structural connectivity between anxious depressed and non-anxious depressed individuals. This study compared fractional anisotropy (FA) and density of selected white matter tracts and amygdala volume between anxious depressed and non-anxious depressed individuals.

METHODS

64- direction DTI and T1 scans were collected from 110 unmedicated subjects with MDD, 39 of whom had a co-morbid anxiety disorder diagnosis. Region of interest (ROI) and tractography methods were performed to calculate amygdala volume and FA in the uncinate fasciculus, respectively. Diffusion connectometry was performed to identify whole brain group differences in white matter health. Correlations were computed between biological and clinical measures.

RESULTS

Tractography and ROI analyses showed no significant differences between bilateral FA values or bilateral amygdala volumes when comparing the anxious depressed and non-anxious depressed groups. The diffusion connectometry analysis showed no significant differences in anisotropy between the groups. Furthermore, there were no significant relationships between MRI-based and clinical measures.

CONCLUSION

The lack of group differences could indicate that structural connectivity and amygdalae volumes of those with anxious-depression are not significantly altered by a co-morbid anxiety disorder. Improving understanding of anxiety co-morbid with MDD would facilitate development of treatments that more accurately target the underlying networks.

Concept Analysis of Posttraumatic Stress Disorder

PURPOSE

Mental health nursing is not the same as psychiatry, so it is important for nurses to have an understanding of the defining attributes, antecedents, consequences, model cases, and empirical referents of post-traumatic stress disorder (PTSD).

METHOD

Walker and Avant's (2005) method is used to guide this concept analysis of PTSD.

FINDINGS

Four attributes arise from this concept analysis, which are addressed through both the DSM-IV and DSM-5 (American Psychiatric Association, /): triggering event or events, re-experiencing, fear, and helplessness. Though a majority of the defining attributes are addressed through both versions of the DSM, a key fifth attribute arises through this concept analysis: a disruption of meaning.

CONCLUSIONS

A better understanding of PTSD from a nursing perspective will help inform appropriate nursing interventions and prevention strategies, while expanding the knowledge synthesis and contribution of the nursing profession.

PRACTICE IMPLICATIONS

A model case, borderline case, and contrary case of PTSD are provided. Discussion of the importance of a lack or loss of meaning in PTSD is included, along with exploration of transformative learning theory to inform clinical practice for nurses addressing a disruption of meaning.

Anesthetic dreaming, anesthesia awareness and patient satisfaction after deep sedation with propofol target controlled infusion: A prospective cohort study of patients undergoing day case breast surgery

Background

Anesthetic dreaming and anesthesia awareness are well distinct phenomena. Although the incidence of intraoperative awareness is more common among patients who reported a dream after surgery, the exact correlation between the two phenomena remains an unsolved rebus. The main purpose of this study was to investigate anesthetic dreaming, anesthesia awareness and psychological consequences eventually occurred under deep sedation. Intraoperative dreaming experiences were correlated with dream features in natural sleep.

Methods

Fifty-one patients, undergoing surgical excision of fibroadenomas under a Bispectral index-guided deep sedation anesthesia with propofol target controlled infusion, were enrolled into this prospective study. Psychological assessment was performed through the State Trait Anxiety Inventory. A questionnaire was adopted to register dreaming and anesthesia awareness. Data were collected after emergence (t0), 24 hours (t1), 1 month (t2), 6 months (t3).

Results

Six patients (12%) reported anesthetic dreaming at t0 confirming the response at each subsequent evaluation. One patient (2%) confirmed dreaming during anesthesia in all, but denied it at t0. There was a high correlation between the intraoperative dream contents and the features of dreams in natural sleep. No cases of anesthesia awareness were detected. A similar level of satisfaction was observed in dreaming and no-dreaming patients.

Conclusions

Anesthetic dreaming does not seem to influence satisfaction of patients undergoing deep sedation with propofol target controlled infusion. A psychological assessment would seem to improve the evaluation of possible psychological consequences in dreamer patient.
