Abnormal emotional processing in maltreated children diagnosed of Complex Posttraumatic Stress Disorder

The Impact of Maternal Interpersonal Violent Trauma and Related Psychopathology on Child Outcomes and Intergenerational Transmission

PURPOSE OF REVIEW

This review aims to outline some consequences that maternal history of trauma with and without related psychopathology, such as posttraumatic stress symptoms (PTSS), can have on their children's development and functioning. It then addresses mechanisms through which intergenerational transmission of interpersonal violence (IPV) and related psychopathology may occur.

RECENT FINDINGS

Findings include the effects of maternal IPV experience and related psychopathology on child social-emotional and biologically-based outcomes. This includes increased developmental disturbances and child psychopathology, as well as physiological factors. Secondly, the review focuses on psychobiological mechanisms by which maternal experience of IPV and related psychopathology likely trigger intergenerational effects. Maternal IPV and related psychopathology can have a negative impact on several areas of their child's life including development, interactive behavior, psychopathology, and physiology. This transmission may partially be due to fetal and perinatal processes, genetic and epigenetic effects, and interactions with their parents.

The Impact of Complex PTSD on Suicide Risk in Patients with Bipolar Disorder: A Cross-Sectional Study

BACKGROUND

Patients with bipolar disorder (BD) are more likely than the general population to experience traumatic events, particularly during childhood, and these may predict and be a risk factor for the development of complex PTSD (cPTSD). The presence of multiple traumas plays a relevant role from a psychopathological point of view, but little is known about the effect this may have on suicide attempts in patients with BD.

METHODS

A cross-sectional study was conducted comparing socio-demographic and clinical characteristics, recruiting 344 patients diagnosed with BD I and II, screened for the presence (or absence) of cPTSD using the International Trauma Questionnaire (ITQ). Suicide attempts were assessed directly during the clinical interview and from the patient's medical record.

RESULTS

The results emerging from the study indicate that cPTSD can be considered a risk factor for suicide attempts in patients with BD. Furthermore, evidence is provided to support the idea that cPTSD is highly prevalent in patients with BD and is related to a higher psychopathological burden.

CONCLUSIONS

The results recommend an urgent and comprehensive assessment of suicidal risk in patients with comorbidity of both bipolar disorder and cPTSD. There is a crucial demand for early intervention initiatives and proactive prevention strategies to address the intricate intersection of these mental health challenges.

Are Socially Relevant Scenes Abnormally Processed in Complex Trauma-Exposed Children?

Abnormal attentional processes to socially relevant information may underlie behavioral dysfunctional symptoms in children exposed to a complex trauma. Attentional biases to social scenes close to real-world situations and their association with behavioral symptomatology were examined in complex trauma-exposed children. A visual dot-probe task involving neutral versus emotional (i.e., threatening, sad, or happy) scenes was applied to twenty-one maltreated children (mean age 10.43; 42.8% female; 61.1% White). These children were exposed to a complex trauma (i.e., severe, repeated, multiple, prolonged, and interpersonal) and were safeguarded in a juvenile welfare home after all parental responsibility was removed. Twenty-four comparable non-maltreated children (mean age 10.13; 29.2% female; 76% White), served as control group. All participants were at risk of social exclusion and every legal representative completed the Child Behavior Checklist (CBCL). Complex trauma-exposed children showed an attentional bias toward threatening scenes, while the control group showed an attentional bias toward sad scenes. There were no differences for happy scenes between groups. Attentional bias toward threatening scenes was associated with withdrawn symptoms in complex trauma-exposed children. Children exposed to a complex trauma show an abnormal attention to threatening social situations, which can trigger maladaptive behaviors such as withdrawn. The understanding of how complex trauma-exposed children process affective environmental information may provide new targets in the social skills interventions such as diminishing maladaptive behaviors and improving coping strategies to face threatening situations.

Contribution of Social Psychology Research to the Sustainable Development Goals (SDGs). Bibliometric and Content Analysis of Spanish Publications

This study analyses the publications by Spanish institutions indexed by the Web of Science in the thematic category of "Psychology, Social". The objectives are to determine whether such publications address topics related to the Sustainable Development Goals (SDGs) and to what extent the research conducted contributes to achieving the goals proposed in each of the SDGs. Publications were classified by their relationship with the SDGs using OSDG tool, and an in-depth content analysis was performed to validate the results. A corpus of 1,632 papers published by Spanish institutions was identified. The results show that 34% percent of the papers address matters related to the SDGs; 23% of these are related to Goal 3 (good health and well-being), and 5%, to Goal 5 (gender equality). For achieving SDG 3 goals, the reviewed papers evidence the need that institutions, governments and society to provide, especially for children and adolescents, healthy social environments to prevent harmful social relationships while improving individual skills to manage emotions in everyday life and promoting cultural integration. Regarding SDG 5, it should be a priority the application of effective strategies to change stereotypes, assigned sexual roles and sexist attitudes that sustain inequality and violence against women.

Childhood maltreatment history and attention bias variability in healthy adult women: role of inflammation and the BDNF Val66Met genotype

Childhood maltreatment has been associated with greater attention bias to emotional information, but the findings are controversial. Recently, a novel index of attention bias, i.e., attention bias variability (ABV), has been developed to better capture trauma-related attentional dysfunction. However, ABV in relation to childhood trauma has not been studied. Here, we examined the association of childhood maltreatment history with attention bias/ABV in 128 healthy adult women. Different types of childhood maltreatment were assessed with the Childhood Trauma Questionnaire. Attention bias/ABV was measured by the dot-probe task. Possible mechanisms whereby childhood maltreatment affects attention bias/ABV were also explored, focusing on blood proinflammatory markers and the BDNF Val66Met polymorphism. We observed a significant positive correlation between childhood emotional abuse and ABV (P = 0.002). Serum high-sensitivity tumor necrosis factor-α levels were significantly positively correlated with ABV (P < 0.001), but not with childhood maltreatment. Jonckheere-Terpstra trend test showed a significant tendency toward greater ABV with increasing numbers of the BDNF Met alleles (P = 0.021). A two-way analysis of variance further revealed that the genotype-by-emotional abuse interaction for ABV was significant (P = 0.022); individuals with the Val/Met and Met/Met genotypes exhibited even greater ABV when childhood emotional abuse was present. These results indicate that childhood emotional abuse can have a long-term negative impact on emotional attention control. Increased inflammation may be involved in the mechanism of ABV, possibly independently of childhood maltreatment. The BDNF Met allele may dose-dependently increase ABV by interacting with childhood emotional abuse.

The Tern Programme Study protocol for an implementation trial of a flexible, long-term psychosocial intervention for complex posttraumatic stress in young people

BACKGROUND

Complex Trauma (CT) is a term used to refer to multiple or prolonged traumatic experiences. Such experiences are often first encountered during childhood and may impact key developmental periods. CT is a risk for a broad range of deleterious physical, psychological, social, and occupational outcomes. The diagnosis of Complex Posttraumatic Stress Disorder (C-PTSD) has been proposed to capture the symptomatology resulting from CT exposure.In Australia, there are few publicly funded services that target, and are purposely designed to support, the mental health needs of young people with symptoms of complex post-traumatic stress (C-PTSD). The Tern Programme has been designed as a purpose-built model of care for providing mental health support to young people with C-PTSD.

METHODS

This implementation trial will involve a longitudinal examination of Tern participants for a fixed 24-month period. Participants will be recruited from the young people referred to Tern at headspace centres in regional Australia where Tern operates. Eligible participants will have reported a history of complex trauma, and present with symptoms of C-PTSD. All participants will be invited to complete a series of surveys during their participation in the programme. Survey items will assess C-PTSD symptom change, quality of life and occupational functioning.The Tern model of care is delivered in a semi-structured format to accommodate a person-centred flexible approach. Fidelity will be monitored through the completion of a clinician post-session checklist and through group supervision.

DISCUSSION

This study will provide the first quantitative data on the new Tern model of care and evaluate mental health and functional outcomes of its participants. If effective, Tern may be suitable for replication in other Australian or international youth mental health services where complex post-traumatic stress is prevalent.

Complex PTSD in survivors of intimate partner violence: risk factors related to symptoms and diagnoses

BACKGROUND

In 2018, the World Health Organization proposed a new diagnosis entitled Complex Posttraumatic Stress Disorder (CPTSD) in the ICD-11. It is a diagnosis that encompasses the classic symptoms of PTSD, along with symptoms of disturbances in self-organization (DSO). Although this disorder has been studied in several countries and populations, research on the population of women survivors of intimate partner violence (IPV) is scarce.

OBJECTIVES

1) To analyse the prevalence of CPTSD and PTSD according to ICD-11 criteria; 2) To analyse the associations between CPTSD symptomatology and severity of violence, level of fear, resilience and strategies of emotion regulation; 3) To analyse which risk factors (severity of violence, level of fear, resilience and strategies of emotion regulation) may differ between female survivors with CPTSD or PTSD.

METHOD

162 women IPV survivors who completed a socio-demographic and violence-related interview, as well as questionnaires to assess PTSD and CPTSD, severity of violence, resilience and emotion regulation strategies.

RESULTS

The results showed a higher prevalence of CPTSD (39.50%), compared to PTSD (17.90%). Moreover, a high level of fear was related to re-experiencing in the here and now, avoidance, current sense of threat and disturbances in relationships. Low levels of resilience and maladaptive emotion regulation strategies such as expressive suppression were related to affective dysregulation, negative self-concept and disturbances in relationships. Finally, the results showed that maladaptive emotion regulation strategies differentiated between meeting CPTSD and PTSD criteria in women survivors of IPV.

CONCLUSION

The findings of this study indicated that CPTSD was twice as prevalent as PTSD within the sample. Moreover, maladaptive emotion regulation strategy as expressive suppression was the main variable related to experiencing CPTSD, in contrast to PTSD. These findings may have important implications for the design of specific treatments aimed at women survivors of IPV, who also suffer CPTSD.

The Relevance of Cognitive Behavioral Models of Post-Traumatic Stress Following Child Maltreatment: A Systematic Review

While it is known that young people exposed to maltreatment or abuse are at elevated risk of developing post-traumatic stress disorder (PTSD), much of our current knowledge of mechanisms that link trauma to childhood PTSD is based on single-incident, often noninterpersonal, trauma. Theoretical models highlight psychological processes of appraisals, memory, and coping as important for the development of PTSD. The aim of this review was to synthesize the literature on the role of these key psychological processes in relation to PTSD in maltreated children and teens. Studies were included if they (1) identified a sample of maltreated individuals, ≤18 years old; (2) measured (a) trauma memory, (b) appraisals, or (c) post-trauma cognitive or behavioral responses; and (3) measured PTSD symptoms. The systematic search of three electronic databases (American Psychological Association PsychNet, PubMed, and Published International Literature on Traumatic Stress) resulted in the inclusion of 36 papers, which described 31 studies and 33 unique samples. The review found cognitive behavioral models of PTSD appeared appropriate for understanding outcomes following maltreatment, but further research is needed on all processes, particularly trauma memory. Overall, there remain significant gaps in our knowledge of how psychological processes link maltreatment to PTSD. There is limited evidence concerning how maltreatment-related characteristics (e.g., chronicity, duration, and type of abuse) influence psychological processes and in turn affect outcomes. This review recommends further research in this area and suggests that, at the very least, comprehensive assessment should be conducted with all young people reporting maltreatment to identify appraisals and coping strategies that will potentially impact on their ongoing adjustment.

COVID-19-related fear and stress among individuals who experienced child abuse: The mediating effect of complex posttraumatic stress disorder

BACKGROUND

The COVID-19 pandemic exposes individuals not only to health-related risks, but also to psychosocial fear and acute stress. Previous studies reveal that individuals who experienced child abuse (CA), especially those who suffer from complex posttraumatic stress disorder (CPTSD), are at a higher risk of reacting with fear and stress when faced with stressful life-events.

OBJECTIVE

To test whether exposure to CA is implicated in a higher risk of COVID-19-related fear and acute stress, and whether CPTSD intervenes in such processes.

PARTICIPANTS AND SETTINGS

A convenience sample of 837 adults participated in the study during the first peak of COVID-19 in Israel.

METHODS

Participants completed self-report questionnaires, assessing child physical, sexual and emotional abuse, CPTSD (ITQ), COVID-19-related acute stress disorder (COVID-19 ASD; ASDS) and fear of COVID-19.

RESULTS

Bivariate analyses showed that participants who experienced CA were higher than participants who did not experience CA in COVID-19 ASD (p = .032), but not in fear of COVID-19 (p = .65). Mediation analyses demonstrated two significant paths: in the first, CA was associated with elevated fear of COVID-19 (effect = .061, .059; p < 0.05) and COVID-19 ASD (effect = .14, .084; p < 0.05) through the mediation of CPTSD; in the second path, when controlling for the mediation of CPTSD, CA was associated with reduced fear of COVID-19 (effect = -.15; p = 0.001), and COVID-19 ASD (effect = -.12; p = 0.024).

CONCLUSIONS

The findings reveal a complex pattern, indicating that CPTSD may be a risk factor for elevated levels of COVID-19 distress among individuals who experienced CA. However, some CA survivors may express reduced COVID-19 distress.

Anxiety and Attentional Bias in Children with Specific Learning Disorders

Children with specific learning disorders (SLDs) face a unique set of socio-emotional challenges as a result of their academic difficulties. Although a higher prevalence of anxiety in children with SLD is often reported, there is currently no research on cognitive mechanisms underlying this anxiety. One way to elucidate these mechanisms is to investigate attentional bias to threatening stimuli using a dot-probe paradigm. Our study compared children ages 9-16 with SLD (n = 48) to typically-developing (TD) controls (n = 33) on their attentional biases to stimuli related to general threats, reading, and stereotypes of SLD. We found a significant threat bias away from reading-related stimuli in the SLD, but not TD group. This attentional bias was not observed with the general threat and stereotype stimuli. Further, children with SLD reported greater anxiety compared to TD children. These results suggest that children with SLD experience greater anxiety, which may partially stem from reading specifically. The finding of avoidance rather than vigilance to reading stimuli indicates the use of more top-down attentional control. This work has important implications for therapeutic approaches to anxiety in children with SLD and highlights the need for attention to socio-emotional difficulties in this population. Future research is needed to further investigate the cognitive aspects of socio-emotional difficulties in children with SLD, as well as how this may impact academic outcomes.

Complex psychological trauma as a consequence of extreme stress

The article presents a brief review of the concept of complex psychological trauma transformations over thirty years, which occurred since the moment when the term Complex Post-traumatic Stress Disorder (C-PTSD) was proposed as a clinical syndrome of multiple psychological traumatization to its official recognition as a diagnostic construct. The article analyzes the dynamics of ideas about the causes and the nature of psychological trauma manifestations under the influence of extreme stress factors, which is reflected in the current nomenclatures of mental and somatic disorders. A comparative analysis of the specific characteristics of various types of psychological traumas that intersect with the term complex PTSD in the conceptual field of trauma psychology is presented. The basic characteristics of complex psychological trauma that distinguish it from similar terms are defined, and the ways of further research in this direction are outlined.

Effects of early maternal care on adolescent attention bias to threat in nonhuman primates

Attention bias towards threat using dot-probe tasks has mainly been reported in adults with stress-related disorders such as PTSD and other anxiety disorders, in some cases associated with early life stress or traumatic experiences. Studies during adolescence are scarce and inconsistent, which highlights the need to increase our understanding of the developmental processes that predict attentional biases, given that this is a time of emergence of psychopathology. Here, we use a translational nonhuman primate model of early life stress in the form of infant maltreatment to examine its long-term impact on attentional biases during adolescence using the dot-probe task and identify interactions with early life risk factors, such as prenatal exposure to stress hormones and emotional/stress reactivity during infancy. Maltreated animals showed higher reaction times to social threat than animals that experienced competent maternal care, suggesting interference of negative valence stimuli on attentional control and cognitive processes. Higher emotional reactivity during infancy in Maltreated animals predicted attention bias towards threat, whereas higher levels of prenatal cortisol exposure was associated with bias away (avoidance of) threat in maltreated and control groups. Our findings suggest that different postnatal experiences and early biobehavioral mechanisms regulate the development of emotional attention biases during adolescence.

Attention biases and social-emotional development in preschool-aged children who have been exposed to domestic violence

BACKGROUND

School-aged children and adolescents exposed to domestic violence (DV) disproportionality attend to threatening and sad cues in their environment. This bias in attention has been found to predict elevations in symptoms of psychopathology. Studies have yet to explore attention biases using eyetracking technology in preschool-aged children with DV exposure.

OBJECTIVE

This study investigated whether preschool-aged children exposed to DV show vigilance to angry and sad faces versus happy faces and a target non-face stimulus relative to non-exposed children, and whether such vigilance relates to child social-emotional development.

PARTICIPANTS AND SETTING

Preschool-aged children were recruited from a large, diverse, urban community. DV-exposed children were recruited from a dyadic, mother-child treatment group specifically designed for, and restricted to, mothers who have experienced domestic violence (DV-exposed group, n = 23). Children with no prior exposure to DV and their mothers were recruited within the same community (non-exposed group, n = 32).

METHODS

Children completed an eye-tracking task to assess their attention to face stimuli and mothers rated their children's social-emotional development. Total duration of fixations were analyzed.

RESULTS

Results showed that DV-exposed children have a significantly stronger attention bias away from sad faces (p = 0.03; d = 0.62) and neutral faces (p = 0.02; d = 0.70) relative to non-exposed children, and this attention bias away from sad and neutral faces is associated with child social-emotional problems. Contrary to our hypothesis, no bias towards anger was found for DV-exposed versus non-exposed children.

CONCLUSIONS

This study contributes to growing evidence that young children's negative attention biases influence functioning and have important implications for children's well-being and development.
