Abstract
Childhood maltreatment is linked to deleterious outcomes, whereby post-traumatic stress disorder (PTSD) has been identified as one of the most debilitating. This retrospective chart review examined whether self-reported affective measures (anxiety, depression, trauma), type of maltreatment (sexual, physical, emotional/verbal abuses), and demographics predicted a diagnosis of anxiety or PTSD among 169 children in a psychiatric inpatient hospital. Secondly, this study identified significant predictors of a PTSD diagnosis. Results indicated self-reported anxiety predicted a diagnosis of PTSD, while self-reported depression predicted PTSD only in maltreated children. Self-reported trauma predicted an anxiety diagnosis. PTSD risk variables including duration of stay, sex, self-reported anxiety, presence of sexual abuse, and presence of emotional/verbal abuse, showed sound sensitivity/specificity as predictors of risk for a PTSD diagnosis in an inpatient setting. Clinical implications are discussed.

Abstract
Adverse childhood experiences (ACEs) before the age of 18 years are pervasive and noteworthy public health concerns. The ACEs are associated with sleep disorders in later life. In this study, we conduct a systematic review to explore the effects of ACEs on sleep in adulthood. Using Medical Subject Headings keywords, we searched Medline, PubMed, PubMed Central, the American Psychological Association PsycArticles, and PsychInfo databases to evaluate the association between ACEs and sleep disturbances. ACEs increase the odds of developing chronic short sleep duration, that is, <6 hours of sleep per night compared with optimal sleep duration of 7-9 hours per night during adulthood. The ACEs are positively associated with poor sleep characteristics such as short sleep duration and long-term sleep problems. Clinicians should pay close attention to developmental trauma care, access community health programs, and help develop better coping skills, resiliency, and good sleep habits in their patients.

Abstract
There are preliminary findings that repetitive thinking on social situations (post-event processing; PEP) is associated with impaired cortisol recovery after experiencing social evaluative stressors. However, no studies have examined the effect of experimental manipulation of PEP on cortisol recovery among socially anxious individuals. The aim of the present study was to examine the effect of distraction on cortisol recovery following a social-evaluative stressor in individuals with subclinical social anxiety symptoms. A total of 40 participants, who scored >30 on the Liebowitz Social Anxiety Scale, completed a standardized stress test (the Trier Social Stress Test; TSST). They were then randomized to complete either a 10-min distraction or PEP induction task. Subjective anxiety and salivary cortisol levels were assessed at −20, −10, 0, +10, +20, +30, +40, and +50 min, with respect to the TSST offset. Contrary to the hypothesis, no difference in cortisol recovery was observed between distraction induction and PEP induction. These findings suggest that short-term distraction induction may not be sufficient to promote cortisol recovery in individuals with elevated social anxiety. Effect of distraction on cortisol recovery was tested in individuals with elevated social anxiety. No effect of distraction on cortisol recovery in comparison to post-event processing induction. Short-term distraction induction may not be sufficient for individuals with social anxiety to promote cortisol recovery.

Abstract
Previous work from our lab has shown that basal cortisol levels are different between healthy young adults who spontaneously use caudate nucleus-dependent response strategies compared to young adults who use hippocampus-dependent spatial navigation strategies. Young adults who use caudate nucleus dependent strategies display lower basal cortisol levels compared to those who use hippocampus-dependent strategies. In the current study, we assessed navigation strategies in children using a virtual navigation task and measured cortisol at baseline as well as cortisol reactivity to both a psychological and to a physical stressor. Replicating what is observed in adults, we found that children who used caudate nucleus-dependent navigation strategies displayed lower cortisol levels at baseline compared to those who used hippocampus-dependent strategies. The psychological stressor, knowledge that a blood draw would be performed by a nurse, caused a significant increase in cortisol uniquely in response learners. The physical stressor, the actual blood draw, produced a significant increase in cortisol amongst spatial learners that was then comparable to levels observed in response learners. Lower baseline cortisol and higher cortisol psychological stress response observed amongst children who used response strategies may therefore reflect early biological changes during development which may have an impact later in life when considering risk for neuropsychiatric disorders. Both adults and children rely of different navigation strategies to learn new environments. Cortisol levels differ between people dependent on spontaneous navigation strategy. We show a differential cortisol stress response in children dependent on navigational strategy.

The differential calibration of the HPA axis as a function of trauma versus adversity: A systematic review and p-curve meta-analyses. Neurosci Biobehav Rev 2021; 127:54-135.

Abstract
Although there is an abundance of evidence linking the function of the hypothalamic-pituitary-adrenal (HPA) axis to adverse early-life experiences, the precise nature of the association remains unclear. Some evidence suggests early-life adversity leads to cortisol hyper-reactivity, while other evidence suggests adversity leads to cortisol hypo-reactivity. Here, we distinguish between trauma and adversity, and use p-curves to interrogate the conflicting literature. In Study 1, trauma was operationalized according to DSM-5 criteria; the p-curve analysis included 68 articles and revealed that the literature reporting associations between trauma and blunted cortisol reactivity contains evidential value. Study 2 examined the relationship between adversity and cortisol reactivity. Thirty articles were included in the analysis, and p-curve demonstrated that adversity is related to heightened cortisol reactivity. These results support an inverted U-shaped function relating severity of adversity and cortisol reactivity, and underscore the importance of distinguishing between "trauma" and "adversity".

Abstract
Family-of-origin aggression (FOA) exposure is a chronic childhood stressor that has been linked to altered stress reactivity of the hypothalamic-pituitary-adrenal (HPA) axis in adulthood. The effects of FOA also spill over between partners in romantic couples, such that one partner's FOA history influences the other's HPA reactivity during couple interactions. However, the direction of these effects is inconsistent, with both heightened and blunted HPA reactivity observed; this heterogeneity suggests the presence of moderators. This study measured HPA reactivity during emotionally vulnerable conversations between young adult romantic partners to assess whether romantic attachment avoidance accounts for this divergence by moderating actor and partner effects of FOA on HPA. A total of 112 opposite-sex couples (224 young adults) provided information on FOA and avoidance, completed dyadic interaction procedures, and provided saliva samples to assess HPA reactivity during interactions. Multilevel structural equation models revealed that FOA did not predict either the actor's or the partner's HPA reactivity. However, FOA and avoidance interacted to produce both actor and partner effects, such that greater FOA exposure heightened HPA reactivity when avoidance was high but blunted reactivity when avoidance was low. The results support the conjecture that proximal relationship-related characteristics, such as attachment avoidance, influence whether distal relationship-related stressors, such as FOA, amplify or attenuate physiological reactivity during emotionally vulnerable interactions. Because HPA reactivity has been linked to a variety of health outcomes, identifying relationship-related buffers of associations between FOA and HPA response may inform future interventions to protect health for FOA-exposed youth.

Abstract
BACKGROUND Childhood interpersonal violence is linked to obesity and central adiposity in adulthood. Victimization experiences are likely to co-occur within individuals, but few studies have examined poly-victimization in the context of obesity and central adiposity. PURPOSE The aim of this study is to evaluate the relationship between poly-victimization and body mass index (BMI) and waist circumference (WC) and to explore whether dysregulation of the hypothalamic-pituitary-adrenal axis, as measured by the cortisol stress response, mediates the relationship. METHODS Healthy undergraduate women were recruited for a laboratory study from an online survey that assessed six different childhood victimization experiences: physical abuse, sexual abuse, peer violence, intimate partner violence, community violence, and witnessing violence. Forty-four women were categorized as poly-victims (2-5 types of violence exposures) and 48 were controls (0 types of violence exposures). Salivary cortisol was measured before and after the Trier Social Stress Test. Cortisol stress response was analyzed by the area under the curve with respect to ground (AUCG). RESULTS Compared with controls, poly-victims had higher BMI (B = 2.03, p = .04) and lower cortisol AUCG (B = -6.70, p < .01), independent of covariates. Poly-victims showed blunted AUCG in response to the stress task compared with controls, independent of covariates (B = -6.70, p < .01). Bootstrapping tests of mediation showed that cortisol response was not a significant mediator of the relationship between poly-victimization and BMI. Secondary analyses among poly-victims showed that the more frequent the violence exposure the higher the BMI. CONCLUSIONS Childhood poly-victimization is linked to higher BMI and blunted cortisol responses in young adult women. Assessment of multiple forms of childhood victimization is recommended.

Abstract
Despite extensive literature positing the hypothalamic-pituitary-adrenal (HPA) axis as a mechanism in the association between early childhood maltreatment and later adult psychopathology, empirical support for this full pathway is lacking. We tested indirect effects of childhood maltreatment on women's later affective symptomatology via HPA axis responding to a stressor involving their own infant. Women (n = 47) in a larger longitudinal study were assessed following the birth of their infant from 3 to 18 months postnatal. They reported childhood maltreatment history at 3 months and participated in a dyadic stress task with their infant at 12 months, at which time four salivary cortisol samples were collected to assess HPA response. Depression and anxiety symptoms at 18 months (controlling for symptom levels reported at 12 months) served as the primary outcome. Multilevel modeling was used to estimate both levels and dynamics of women's cortisol response trajectories. Tests of indirect effects revealed a significant effect of total Childhood Trauma Questionnaire (CTQ) scores on anxiety symptoms and a marginally significant effect on depression symptoms. Follow-up analyses with CTQ subscales revealed significant indirect effects of emotional and physical abuse on women's ongoing anxiety symptoms via more pronounced cortisol reactivity curves during the mother-infant stressor. We discuss methodological choices that may have allowed these effects to be detected in the present study and implications for stress-related risk and intervention.

Abstract
This study examined the cognitive mechanism underlying acute stress in creative cognition among individuals with high and low trait anxiety. Specifically, cognitive inhibition was assessed using the flanker task during acute stress. Fifty-two participants (26 with high trait anxiety, 26 with low trait anxiety, with a mean age of 18.94 years) underwent stress induction via the Trier Social Stress Test (TSST). They all completed the Alternative Uses Test (AUT) and the Remote Associates Test (RAT) before and after the TSST. Biochemical markers (salivary cortisol and salivary alpha amylase) were recorded at regular intervals. The results showed that cognitive inhibition was influenced by trait anxiety and acute stress. In low-trait anxious individuals after experiencing acute stress, there was a lack of cognitive inhibition and they performed better in AUT (fluency), compared to before experiencing acute stress, whereas high-trait anxious individuals showed a decreased interference effect and reduced performance in AUT (fluency, flexibility, and originality). In the RAT, there were shorter response times and increased accuracy after acute stress in both high- and low-trait anxiety groups. Thus, we suggest that cognitive control, which modulates changes in acute stress, influences creative cognition. These findings provide evidence that inhibition control mediates the effect of stress on the creativity of individuals with different trait anxiety.

Abstract
Repeated exposure to stress during early life has a lifetime impact on physical and psychological functions. Our study investigated the long-term effects of early life stress (ELS; measured retrospectively) on the hypothalamic-pituitary-adrenal (HPA) axis and sympathetic nervous system functions under psychosocial stress among healthy adults. Fifty healthy volunteers (33 male, 17 female, mean age 22.6 ± 1.8 years) underwent a standardized psychosocial stress protocol (the Trier Social Stress Test), with the collection of salivary cortisol, heart rates, and positive and negative affect. The results showed increases in cortisol, heart rate, and negative affect after the stress inducement. More importantly, a significant negative correlation was found between the severity of ELS and the increase of cortisol to the stress. The severity of stress in one's early life predicted his/her cortisol reactivity to the stress in adulthood. Neither the heart rate reactivity nor the affective reactivity shows significant association with ELS. The blunted cortisol reactivity reflects the alteration of the HPA axis, which may confer the risk for certain stress-related disorders.

Abstract
Background Social anxiety disorder (SAD) is one of the most prevalent psychiatric disorders in South Africa. Previous studies have linked childhood trauma with the development of SAD. The behavioural inhibition system (BIS) and the behavioural activation system (BAS), two dimensions of personality related to anxiety and impulsivity, respectively, are said to influence the development of psychopathology, including SAD. Both SAD and childhood trauma have an impact on quality of life. This study investigated the relationship between BIS, BAS and quality of life in patients with SAD with and without exposure to childhood trauma, compared to healthy controls. Method Data were collected for 102 adults. A total of 76 participants met SAD criteria, of which 51 were exposed to childhood trauma and 25 were not. The remaining 26 participants were demographically matched healthy controls. Measures of anxiety, impulsivity and quality of life were obtained by administering Carver and White’s BIS/BAS scales and the Quality of Life Enjoyment and Satisfaction Questionnaire – Self Report. Results A positive correlation was found between the severity of SAD symptoms and the amount of childhood trauma exposure. No significant differences in impulsivity were found across the three groups. Healthy controls reported significantly lower anxiety and a better quality of life than both groups with SAD, while no differences were found between patients with SAD and childhood trauma and those without childhood trauma. Conclusion More childhood trauma exposure appears to be associated with greater SAD severity. The lack of differences in BIS, BAS and quality of life in patients with SAD with or without childhood trauma requires further investigation.

Abstract
Early life adversity is associated with both persistent disruptions in the hypothalamic-pituitary-adrenal (HPA) axis and psychiatric symptoms. Glucocorticoid receptors (GRs), which are encoded by the NR3C1 gene, bind to cortisol and other glucocorticoids to create a negative feedback loop within the HPA axis to regulate the body's neuroendocrine response to stress. Excess methylation of a promoter sequence within NR3C1 that attenuates GR expression, however, has been associated with both early life adversity and psychopathology. As critical regulators within the HPA axis, GRs and their epigenetic regulation may mediate the link between early life adversity and the onset of psychopathology. The present review discusses this work as one mechanism by which stress may get under the skin to disrupt HPA functioning at an epigenetic level and create long-lasting vulnerabilities in the stress regulatory system that subsequently predispose individuals to psychopathology. Spanning prenatal influences to critical periods of early life and adolescence, we detail the impact that early adversity has on GR expression, physiological responses to stress, and their implications for long-term stress management. We next propose a dual transmission hypothesis regarding both genomic and non-genomic mechanisms by which chronic and acute stress propagate through numerous generations. Lastly, we outline several directions for future research, including potential reversibility of methylation patterns and its functional implications, variation in behavior determined solely by NR3C1, and consensus on which specific promoter regions should be studied.

Abstract
PURPOSE Childhood trauma may increase vulnerability to numerous specific psychiatric disorders, or a generalised liability to experience dimensions of internalising or externalising psychopathology. We use a nationally representative sample (N = 34,653) to examine the long-term consequences of childhood trauma and their combined effect as predictors of subsequent psychopathology. METHODS Data from the US National Epidemiologic Survey on Alcohol and Related Conditions were used. Latent class analysis was used to identify childhood trauma profiles and multinomial logistic regression to validate and explore these profiles with a range of associated demographic and household characteristics. We used Structural Equation Modelling to substantiate initial latent class analysis findings by investigating a range of mental health diagnoses. Internalising and externalising domains of psychopathology were regressed on trauma profiles and associated demographic and household characteristics. We used Differential Item Functioning to examine associations between the trauma groups and a number of psychiatric disorders within internalising and externalising dimensions of mental health. RESULTS We found a 3-class model of childhood trauma in which 85% of participants were allocated to a low trauma class; 6% to a multi-type victimization class (reporting exposures for all the child maltreatment criteria); and 9% to a situational trauma class (exposed to a range of traumas). Confirmatory Factor Analysis revealed an internalising-externalising spectrum was used to represent lifetime reporting patterns of mental health disorders. Both trauma groups showed specific gender and race/ethnicity differences, related family discord and increased psychopathology. Additionally, we found significant associations between the trauma groups and specific diagnoses within the internalising-externalising spectrum of mental health. CONCLUSIONS The underlying patterns in the exposure to types of interpersonal and non-interpersonal traumas and associated mental health highlight the need to screen for particular types of childhood traumas when individuals present with symptoms of psychiatric disorders.

Abstract
Social stress occurs in all social species, including humans, and shape both mental health and future interactions with conspecifics. Animal models of social stress are used to unravel the precise role of the main stress system - the HPA axis - on the one hand, and the social behavior network on the other, as these are intricately interwoven. The present review aims to summarize the insights gained from three highly useful and clinically relevant animal models of psychosocial stress: the resident-intruder (RI) test, the chronic subordinate colony housing (CSC), and the social fear conditioning (SFC). Each model brings its own focus: the role of the HPA axis in shaping acute social confrontations (RI test), the physiological and behavioral impairments resulting from chronic exposure to negative social experiences (CSC), and the neurobiology underlying social fear and its effects on future social interactions (SFC). Moreover, these models are discussed with special attention to the HPA axis and the neuropeptides vasopressin and oxytocin, which are important messengers in the stress system, in emotion regulation, as well as in the social behavior network. It appears that both nonapeptides balance the relative strength of the stress response, and simultaneously predispose the animal to positive or negative social interactions.

Bunea IM, Szentágotai-Tătar A, Miu AC. Early-life adversity and cortisol response to social stress: a meta-analysis. Transl Psychiatry 2017; 7:1274. [PMID: 29225338 PMCID: PMC5802499 DOI: 10.1038/s41398-017-0032-3] [Citation(s) in RCA: 219] [Impact Index Per Article: 31.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2017] [Accepted: 09/01/2017] [Indexed: 12/11/2022] Open
Abstract
Early-life adversity has been associated with a life-long increased risk for psychopathology and chronic health problems. These long-term negative effects have been explained through stress sensitization, which may involve dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis through either increased or decreased reactivity. The present meta-analysis assessed for the first time the effect of early-life adversity on cortisol response to social stress. Thirty data sets were included in the meta-analysis, in which early-life adversity and salivary cortisol response to social stress were assessed in 4292 individuals of different ages. Results indicated a moderate effect size (g = -0.39) in overall cortisol levels across studies. Separate analyses of cortisol at different stages of response showed large effect sizes at peak and recovery, and a moderate effect at baseline. Heterogeneity was large in this sample of studies and several moderators were identified. The effect size was larger in studies that focused on maltreatment compared to those that included other adversities, and in adults compared to children and adolescents. Percent of women in each sample and methodological quality were positive predictors of the effect size. Publication bias may be present, but the analysis was hampered by the high heterogeneity. Therefore, these results support the association between early-life adversity and blunted cortisol response to social stress, and they suggest that the long-term negative effects of early-life adversity may reach maximum levels in adults.

Abstract
There is growing evidence that individuals with social anxiety show impaired cortisol recovery after experiencing social evaluative stressors. Yet, little is known regarding the cognitive processes underlying such impaired cortisol recovery. The present study examined the effect of post-event processing (PEP), referred to as repetitive thinking about social situations, on cortisol recovery following a social stressor. Forty-two non-clinical university students (23 women, 19 men, mean age = 22.0 ± 2.0 years) completed the Trier Social Stress Test (TSST), followed by a thought sampling procedure which assessed the frequency of PEP reflecting the TSST. A growth curve model showed PEP and social anxiety interactively predicted cortisol recovery. In particular, PEP predicted impaired cortisol recovery in those with low levels of social anxiety but not in those with high levels of social anxiety, which contradicted the initial hypothesis. These findings suggest that PEP is differentially associated with cortisol recovery depending on levels of social anxiety. The possible mechanisms underlying these findings were discussed in terms of protective inhibition framework.

Abstract
HPA axis functioning plays an important role in the etiology of schizophrenia spectrum disorders (SSD). However, only few studies have examined HPA axis responsivity to psychosocial stress in SSD, and results are heterogeneous. Furthermore, childhood trauma is known to influence psychopathology and treatment outcome in SSD, but studies on the influence of childhood trauma on stress related HPA axis activity are missing. The purpose of this study was to investigate cortisol response to a psychosocial stress challenge in SSD patients, and to examine its association with severity of childhood trauma. The present study included 25 subacutely ill patients with a current episode of a chronic SSD and 25 healthy controls. Participants underwent the modified Trier Social Stress Test, and salivary cortisol levels were assessed. The childhood trauma questionnaire was used to assess severity of adverse life events. Overall, cortisol response was blunted in the patient group compared to the control group (p<0.01). Furthermore, we identified two patient subgroups (cortisol responders (n=12) vs. non-responders (n=13) to the modified TSST) that differed in their severity of childhood trauma experience: responders had experienced more emotional abuse in their past (p<0.042). Therefore, childhood trauma might influence stress-related HPA axis activity in SSD. Our data contribute to the hypothesis that severity of childhood trauma may be of pathophysiological relevance in schizophrenia. In addition, it may be an overlooked factor contributing to inconsistent findings regarding HPA axis response to psychosocial stress in SSD.

Abstract
Social anxiety disorder (SAD) is characterised by a marked and persistent fear of social/performance situations, and a number of key environmental factors have been implicated in the aetiology of the disorder. Hence, the current article reviews theoretical and empirical evidence linking the development of SAD with parenting factors, traumatic life events, and aversive social experiences. Specifically, research suggests that the risk of developing SAD is increased by over-controlling, critical and cold parenting, an insecure attachment style, aversive social/peer experiences, emotional maltreatment, and to a lesser extent other forms of childhood maltreatment and adversity. Moreover, these factors may lead to posttraumatic reactions, distorted negative self-imagery, and internalised shame-based schemas that subsequently maintain SAD symptomatology. However, further research is necessary to clarify the nature, interactions, and relative contributions of these factors. It is likely that SAD develops via a complex interplay of biological and environmental factors, and that multiple aetiological pathways underlie the development of the disorder.

Abstract
BACKGROUND A proportion of patients with panic disorder (PD) fail to show a remission after psychotherapy. Biological correlates of psychotherapy non-response have rarely been described in the literature. The aim of the present study was to research the relationship between the cortisol stress response and the psychotherapy outcome in PD patients. METHODS Twenty-eight PD patients (20 females, mean age±SD: 35.71±13.18) seeking psychological treatment for PD and n=32 age- and sex-matched healthy control participants (21 females, aged 34.66±12.07) participated in this study. The patients underwent five weeks of cognitive behavioural therapy (CBT). Within the first two weeks of the CBT, both study groups were confronted with the Trier Social Stress Test (TSST). Blood sampling for cortisol and adrenocorticotropic hormone (ACTH) evaluation as well as fear-rating (Visual Analogue Scale; Primary Appraisal and Secondary Appraisal Questionnaire, PASA) accompanied the TSST. The global severity of PD (Panic & Agoraphobia Scale; PAS), agoraphobic cognitions (Agoraphobic Cognitions Questionnaire; ACQ), fear of bodily sensations (Bodily Sensations Questionnaire; BSQ), agoraphobic avoidance (Mobility Inventory; MI), and depressiveness (Beck Depression Inventory; BDI) were assessed before and after the CBT (except the BDI). RESULTS The statistical analysis revealed significant main effects of time for cortisol and the ACTH concentration in response to the TSST, independently of the study group. 42.9% of the PD patients and 65.6% of the healthy control participants showed a cortisol stress response to the TSST≥55.2nmol/l (descriptive finding). The data showed a significant inverse association of the TSST cortisol stress response with the MI total score when accompanied. Further, a significant association of the PASA subjective level of fear and the BSQ as well as a trend for an association of the PASA with the ACQ were observed. CONCLUSION Consistent with prior research, we could replicate findings of decreased cortisol concentrations in the PD patients in comparison to the healthy control participants. Furthermore, our findings agree with previous data showing an association of the attenuated cortisol stress response with the psychotherapy non-response. In the present sample, those patients with the lowest cortisol concentrations showed the least improvement in agoraphobic avoidance after psychotherapy. The patients with the highest level of fear showed the most improvement in fear of bodily sensations. Study limitations as well as implications for future studies will be discussed.

Abstract
BACKGROUND Childhood maltreatment can trigger enduring changes in major stress response systems, particularly in the context of major depressive disorder (MDD). However, the relative impact of maltreatment versus MDD on hypothalamic-pituitary-adrenal axis and sympathetic-adrenal-medullary system stress reactivity is not well understood. METHOD This study examined salivary cortisol and alpha-amylase responses to the Trier Social Stress Test (TSST) in 26 maltreated (15 with current MDD) and 26 non-maltreated (17 with current MDD) women. RESULTS Maltreated women showed greater anticipatory cortisol reactivity during the TSST protocol compared to non-maltreated women. Maltreated women also showed rapid deceleration in cortisol levels. Whereas non-maltreated women showed initial declines in alpha-amylase levels but rapidly increasing alpha-amylase levels during the TSST protocol, maltreated women did not exhibit changes in alpha-amylase levels during the TSST protocol. Contrary to expectation, MDD did not impact cortisol or alpha-amylase responses. LIMITATIONS The present study is limited by retrospective report of childhood maltreatment, cross-sectional design, and modest sample sizes. CONCLUSIONS These findings suggest that childhood maltreatment plays a greater role driving alterations in cortisol and alpha-amylase stress reactivity than MDD. Understanding the biological embedding of maltreatment is critical for elucidating mechanisms linking these experiences to risk for negative mental and physical health outcomes.

Abstract
AbstractVariation in the quality of parental care has a tremendous impact on a child's social–emotional development. Research investigating the predictors of this variability in human caregiving behavior has mostly focused on learning mechanisms. Evidence is currently accumulating for the complementary underlying role of steroid hormones and neuropeptides. An overview is provided of the hormones and neuropeptides relevant for human caregiving behavior. Then the developmental factors are described that stimulate variability in sensitivity to these hormones and neuropeptides, which may result in variability in the behavioral repertoire of caregiving. The role of genetic variation in neuropeptide and steroid receptors, the role of testosterone and oxytocin during fetal development and parturition, and the impact of experienced caregiving in childhood on functioning of the neuroendocrine stress and oxytocin system are discussed. Besides providing a heuristic framework for further research on the ontogenetic development of human caregiving, a neuroendocrine model is also presented for the intergenerational transmission of caregiving practices. Insight into the underlying biological mechanisms that bring about maladaptive caregiving behavior, such as neglect and insensitive parenting, will hopefully result in more efficient approaches to reduce the high prevalence of such behavior and to minimize the impact on those affected.

Abstract
Child maltreatment is a prevalent societal problem that has been linked to a wide range of social, psychological, and emotional difficulties. Maltreatment impacts on two putative evolved psychobiological systems in particular, the attachment system and the social rank system. The maltreatment may disrupt the child's ability to form trusting and reassuring relationships and also creates a power imbalance where the child may feel powerless and ashamed. The aim of the current article is to outline an evolutionary theory for understanding the impact of child maltreatment, focusing on the interaction between the attachment and the social rank system. We provide a narrative review of the relevant literature relating to child maltreatment and these two theories. This research highlights how, in instances of maltreatment, these ordinarily adaptive systems may become maladaptive and contribute to psychopathology. We identify a number of novel hypotheses that can be drawn from this theory, providing a guide for future research. We finally explore how this theory provides a guide for the treatment of victims of child maltreatment. In conclusion, the integrated theory provides a framework for understanding and predicting the consequences of maltreatment, but further research is required to test several hypotheses made by this theory.

Abstract
As prevalence of anxiety, posttraumatic stress, and obsessive compulsive disorders continue to rise worldwide, increasing focus has been placed on immune mediated theories in understanding the underlying mechanisms of these disorders. Associations between the dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and these disorders have been recognized in the scientific literature, specifically in regard to cortisol levels, as well as changes in pro- and anti-inflammatory cytokines. The present commentary will systematically assess the scientific literature within the past decade in regard to the psychoneuroimmunology of anxiety, posttraumatic stress, and obsessive compulsive disorders. Understanding the mechanisms of these disorders is essential in order to determine efficacious and targeted treatment strategies, which may lead to substantial improvements in overall functioning, as well as significant decreases in societal and economic burden.

Abstract
BACKGROUND Meta-analyses link childhood trauma to depression, mania, anxiety disorders, and psychosis. It is unclear, however, whether these outcomes truly represent distinct disorders following childhood trauma, or that childhood trauma is associated with admixtures of affective, psychotic, anxiety and manic psychopathology throughout life. METHOD We used data from a representative general population sample (NEMESIS-2, n = 6646), of whom respectively 1577 and 1120 had a lifetime diagnosis of mood or anxiety disorder, as well as from a sample of patients with a diagnosis of schizophrenia (GROUP, n = 825). Multinomial logistic regression was used to assess whether childhood trauma was more strongly associated with isolated affective/psychotic/anxiety/manic symptoms than with their admixture. RESULTS In NEMESIS-2, largely comparable associations were found between childhood trauma and depression, mania, anxiety and psychosis. However, childhood trauma was considerably more strongly associated with their lifetime admixture. These results were confirmed in the patient samples, in which it was consistently found that patients with a history of childhood trauma were more likely to have a combination of multiple symptom domains compared to their non-traumatized counterparts. This pattern was also found in exposed individuals who did not meet criteria for a psychotic, affective or anxiety disorder and who did not seek help for subclinical psychopathology. CONCLUSIONS Childhood trauma increases the likelihood of a specific admixture of affective, anxiety and psychotic symptoms cutting across traditional diagnostic boundaries, and this admixture may already be present in the earliest stages of psychopathology. These findings may have significant aetiological, pathophysiological, diagnostic and clinical repercussions.

Abstract
This study evaluated the cortisol stress response (CSR) following the Trier Social Stress Test in Social Anxiety Disorder (SAD) and control participants, to determine whether individual differences in CSR associate more with SAD diagnosis or dimensional characteristics [i.e. childhood trauma (CT)]. Twenty-one participants (11 with SAD) had full data available for both CT-scores and cortisol area-under-the-curve (AUC). Linear regression produced significant results: predicting AUCG with study group, emotional abuse (EA) scores and their interaction (F=3.14, df=5,15; p=.039); of note, the study group by EA interaction was significant at p=.015, driven by a strong positive association between EA and cortisol AUCG in the control group, and a negative association between these variables in the SAD group (standardized-beta=1.56, t=2.75, p=.015). This suggests that EA in SAD patients is associated with altered CSR, highlighting need to measure dimensional characteristics.

Abstract
Chronic, in particular chronic psychosocial, stress is a burden of modern societies and known to be a risk factor for numerous somatic and affective disorders (in detail referenced below). However, based on the limited existence of appropriate, and clinically relevant, animal models for studying the effects of chronic stress, the detailed behavioral, physiological, neuronal, and immunological mechanisms linking stress and such disorders are insufficiently understood. To date, most chronic stress studies in animals employ intermittent exposure to the same (homotypic) or to different (heterotypic) stressors of varying duration and intensity. Such models are only of limited value, since they do not adequately reflect the chronic and continuous situation that humans typically experience. Furthermore, application of different physical or psychological stimuli renders comparisons to the mainly psychosocial stressors faced by humans, as well as between the different stress studies almost impossible. In contrast, rodent models of chronic psychosocial stress represent situations more akin to those faced by humans and consequently seem to hold more clinical relevance. Our laboratory has developed a model in which mice are exposed to social stress for 19 continuous days, namely the chronic subordinate colony housing (CSC) paradigm, to help bridge this gap. The main aim of the current review article is to provide a detailed summary of the behavioral, physiological, neuronal, and immunological consequences of the CSC paradigm, and wherever possible relate the findings to other stress models and to the human situation.

Abstract
Adverse childhood experiences (ACEs) represent substantial threats to public health and affect about 58% of youth in the US. In addition to their acute effects such as injury and physical trauma, ACEs are associated with an increased risk of several negative health outcomes throughout the life course. Emerging evidence suggests that sleep disorders may be one such outcome, but existing studies have not been systematically reviewed and summarized. We conducted a systematic review to summarize the evidence concerning the relationship between ACEs and sleep disorders and disturbances, with a focus on adult women. Original publications were identified through searches of the electronic databases MEDLINE, Embase, and Web of Science using the keywords "childhood," "adversity," "abuse," and "sleep" as well as searches of the reference lists of eligible studies. Studies evaluating ACEs that occurred before 18 years of age and sleep outcomes that were assessed at 18 years or older were adjudicated and included. A total of 30 publications were identified. Of the 30 studies, 28 were retrospective analyses and there was vast heterogeneity in the types of ACEs and sleep outcomes measured. The majority of retrospective studies (N = 25 of 28) documented statistically significant associations between sleep disorders including sleep apnea, narcolepsy, nightmare distress, sleep paralysis, and psychiatric sleep disorders with a history of childhood adversity. In many studies, the strengths of associations increased with the number and severity of adverse experiences. These associations were corroborated by the two prospective studies published to date. Notably, investigators have documented statistically significant associations between family conflict at 7-15 years of age and insomnia at 18 years of age (odds ratio, OR = 1.4; 95% confidence interval, CI = 1.2-1.7) and between childhood sexual abuse and sleep disturbances 10 years later in adult women (β = 0.24, p <0.05). There is a growing scientific body of knowledge suggesting an association between ACEs and multiple sleep disorders in adulthood. The available evidence indicates the need to develop treatment strategies such as trauma-informed care for survivors of abuse who suffer from sleep disorders and disturbances. Further, longitudinal studies among diverse populations are needed to improve the overall understanding of this association and to investigate potential gender and racial/ethnic disparities in the strength of the association.

Abstract
The deleterious effects of chronic stress on health and its contribution to the development of mental illness attract broad attention worldwide. An important development in the last few years has been the employment of hair cortisol analysis with its unique possibility to assess the long-term systematic levels of cortisol retrospectively. This review makes a first attempt to systematically synthesize the body of published research on hair cortisol, chronic stress, and mental health. The results of hair cortisol studies are contrasted and integrated with literature on acutely circulating cortisol as measured in bodily fluids, thereby combining cortisol baseline concentration and cortisol reactivity in an attempt to understand the cortisol dynamics in the development and/or maintenance of mental illnesses. The studies on hair cortisol and chronic stress show increased hair cortisol levels in a wide range of contexts/situations (e.g. endurance athletes, shift work, unemployment, chronic pain, stress in neonates, major life events). With respect to mental illnesses, the results differed between diagnoses. In major depression, the hair cortisol concentrations appear to be increased, whereas for bipolar disorder, cortisol concentrations were only increased in patients with a late age-of-onset. In patients with anxiety (generalized anxiety disorder, panic disorder), hair cortisol levels were reported to be decreased. The same holds true for patients with posttraumatic stress disorder, in whom - after an initial increase in cortisol release - the cortisol output decreases below baseline. The effect sizes are calculated when descriptive statistics are provided, to enable preliminary comparisons across the different laboratories. For exposure to chronic stressors, the effect sizes on hair cortisol levels were medium to large, whereas for psychopathology, the effect sizes were small to medium. This is a first implication that the dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis in the development and/or maintenance of psychopathology may be more subtle than it is in healthy but chronically stressed populations. Future research possibilities regarding the application of hair cortisol research in mental health and the need for multidisciplinary approaches are discussed.

Abstract
Given that anxiety is highly familial, the current pilot study explored the association between anxiety diagnosis and diurnal cortisol rhythm in mother-child dyads with the hypothesis that a predisposition toward homogenous cortisol profiles may partially explain the familial linkage of anxiety. The role of family environment in stress response was also examined. Participants were 27 mother-child dyads. Results indicated that patterns of cortisol secretion between mother and child are synchronous. Maternal anxiety and aspects of family functioning significantly predicted child awakening cortisol pattern. Further, affective involvement and gender of the child significantly predicted mother-child diurnal cortisol secretion synchrony. These findings provide support for the degree of synchrony in patterns of physiological responsiveness between mother and child, as well as the importance of a child's affective environment in the prediction of a diagnosis of anxiety.

Abstract
INTRODUCTION There is substantial evidence regarding the impact of negative life events during childhood on the aetiology of psychiatric disorders. We examined the association between negative early life events and social anxiety in a sample of 571 Spanish University students. METHODS In a cross-sectional survey conducted in 2007, we collected data through a semistructured questionnaire of sociodemographic variables, personal and family psychiatric history, and substance abuse. We assessed the five early negative life events: (i) the loss of someone close, (ii) emotional abuse, (iii) physical abuse, (iv) family violence, and (v) sexual abuse. All participants completed the Liebowitz Social Anxiety Scale. RESULTS Mean (SD) age was 21 (4.5), 75% female, LSAS score was 40 (DP = 22), 14.2% had a psychiatric family history and 50.6% had negative life events during childhood. Linear regression analyses, after controlling for age, gender, and family psychiatric history, showed a positive association between family violence and social score (p = 0.03). None of the remaining stressors produced a significant increase in LSAS score (p > 0.05). CONCLUSION University students with high levels of social anxiety presented higher prevalence of negative early life events. Thus, childhood family violence could be a risk factor for social anxiety in such a population.

Abstract
Is an attenuated physiological response to family conflict, seen in some youth exposed to early adversity, protective or problematic? A longitudinal study including 54 youth (average age 15.2 years) found that those with higher cumulative family aggression exposure showed lower cortisol output during a laboratory-based conflict discussion with their parents, and were less likely to show the normative pattern of increased cortisol reactivity to a discussion they rated as more conflictual. Family aggression interacted with cortisol reactivity in predicting youth adjustment: Adolescents from more aggressive homes who were also more reactive to the discussion reported more posttraumatic stress symptoms and more antisocial behavior. These results suggest that attenuated reactivity may protect youth from the negative consequences associated with aggressive family environments.

Abstract
Anxiety disorders are among the most common of all mental disorders and their pathogenesis is a major topic in psychiatry, both for prevention and treatment. Early stressful life events and alterations of hypothalamic pituitary adrenal (HPA) axis function seem to have a significant role in the onset of anxiety. Existing data appear to support the mediating effect of the HPA axis between childhood traumata and posttraumatic stress disorder. Findings on the HPA axis activity at baseline and after stimuli in panic disordered patients are inconclusive, even if stressful life events may have a triggering function in the development of this disorder. Data on the relationship between stress, HPA axis functioning and obsessive-compulsive disorder (OCD) are scarce and discordant, but an increased activity of the HPA axis is reported in OCD patients. Moreover, normal basal cortisol levels and hyper-responsiveness of the adrenal cortex during a psychosocial stressor are observed in social phobics. Finally, abnormal HPA axis activity has also been observed in generalized anxiety disordered patients. While several hypothesis have attempted to explain these findings over time, currently the most widely accepted theory is that early stressful life events may provoke alterations of the stress response and thus of the HPA axis, that can endure during adulthood, predisposing individuals to develop psychopathology. All theories are reviewed and the authors conclude that childhood life events and HPA abnormalities may be specifically and transnosographically related to all anxiety disorders, as well as, more broadly, to all psychiatric disorders.

Abstract
Chronic psychosocial stress has been repeatedly shown in humans to be a risk factor for the development of several affective and somatic disorders, including inflammatory bowel diseases (IBD). There is also a large body of evidence from rodent studies indicating a link between stress and gastrointestinal dysfunction, resembling IBD in humans. Despite this knowledge, the detailed underlying neuroendocrine mechanisms are not sufficiently understood. This is due, in part, to a lack of appropriate animal models, as most commonly used rodent stress paradigms do not adequately resemble the human situation and/or do not cause the development of spontaneous colitis. Therefore, our knowledge regarding the link between stress and IBD is largely based on rodent models with low face and predictive validity, investigating the effects of unnatural stressors on chemically induced colitis. These studies have consistently reported that hypothalamo-pituitary-adrenal (HPA) axis activation during stressor exposure has an ameliorating effect on the severity of a chemically induced colitis. However, to show the biological importance of this finding, it needs to be replicated in animal models employing more clinically relevant stressors, themselves triggering the development of spontaneous colitis. Important in view of this, recent studies employing chronic/repeated psychosocial stressors were able to demonstrate that such stressors indeed cause the development of spontaneous colitis and, thus, represent promising tools to uncover the mechanisms underlying stress-induced development of IBD. Interestingly, in these models the development of spontaneous colitis was paralleled by decreased anti-inflammatory glucocorticoid (GC) signaling, whereas adrenalectomy (ADX) prior to stressor exposure prevented its development. These findings suggest a more complex role of the HPA axis in the development of spontaneous colitis. In the present review I summarize the available human and rodent data in order to provide a comprehensive understanding of the biphasic role of the HPA axis and/or the GC signaling during stressor exposure in terms of spontaneous colitis development.

Abstract
Considerable variability in the activity of the hypothalamus-pituitary-adrenal (HPA) axis in response to stress has been found in quantitative genetic studies investigating healthy individuals suggesting that at least part of this variance is due to genetic factors. Since the HPA axis is regulated by a neuronal network including amygdala, hippocampus, prefrontal cortex as well as brainstem circuits, the investigation of candidate genes that impact neurotransmitter systems related to these brain regions might further elucidate the genetic underpinnings of the stress response. However, aside from genetic risk factors, past stressful life events might also result in long-term adjustments of HPA axis reactivity. Here, we investigated the effects of the -1019 G/C polymorphism in the HTR1A gene encoding the serotonin (5-HT) receptor 1A (5-HT(1A)) and stressful life events experienced during childhood and adolescence on changes in cortisol levels in response to the Trier Social Stress Test (TSST) in a sample of healthy older adults (N=97). Regression analyses revealed a significant effect of HTR1A genotype with the G allele being associated with a less pronounced stress response. In addition, an inverse relationship between past stressful life events and cortisol release but no gene × environment interaction was detected. The results further underscore the crucial role of functional serotonergic genetic variation as well as stressful events during critical stages of development on the acute stress response later in life.

Abstract
BACKGROUND Childhood emotional maltreatment (CEM) has been associated with a profound and enduring negative impact on behavioral and emotional functioning. Animal models have shown that adverse rearing conditions, such as maternal separation, can induce a cascade of long-term structural alterations in the brain, particularly in the hippocampus, amygdala, and prefrontal cortex. However, in humans, the neurobiological correlates of CEM are unknown. METHODS Using high-resolution T1-weighted 3T magnetic resonance imaging, anatomical scans and a whole-brain optimized voxel-based morphometry approach, we examined whether healthy control subjects and unmedicated patients with depression and/or anxiety disorders reporting CEM before age 16 (n = 84; age: mean = 38.7) displayed structural brain changes compared with control subjects and patients who reported no childhood abuse (n = 97; age: mean = 36.6). RESULTS We found that self-reported CEM is associated with a significant reduction in predominantly left dorsal medial prefrontal cortex volume, even in the absence of physical or sexual abuse during childhood. In addition, reduced medial prefrontal cortex in individuals reporting CEM is present in males and females, independent of concomitant psychopathology. CONCLUSIONS In this study, we show that CEM is associated with profound reductions of medial prefrontal cortex volume, suggesting that sustained inhibition of growth or structural damage can occur after exposure to CEM. Given the important role of the medial prefrontal cortex in the regulation of emotional behavior, our finding might provide an important link in understanding the increased emotional sensitivity in individuals reporting CEM.
