Attachment Dimensions and Post-traumatic Symptoms Following Interpersonal Traumas versus Impersonal Traumas in Young Adults in Taiwan

Genetic Contributions on Attachment in Emerging Adults: Cumulative Effects of Serotonergic Polymorphisms

Attachment in emerging adults is closely intertwined with emotion regulation, stress coping, and social bonding during the transition from childhood to early adulthood. Due to the critical roles of serotonin in these mental functions, this research explored whether the cumulative genetic effects of serotonergic polymorphisms are associated with individual differences and contextual variations in attachment dimensions over time in emerging adults. Study 1 utilized a cross-sectional design in college students (N = 1088, mean age = 22.71 ± 2.86 years). The results showed significant correlations between a higher cumulative genetic score and elevated levels of attachment anxiety and avoidance. Study 2 employed a three-wave longitudinal design in a cohort of freshmen (N = 523, mean age = 19.54 ± 1.86 years at wave 1). The results demonstrated that a higher genetic score was associated with both higher levels and greater variability in attachment dimensions compared to a lower genetic score. These findings suggest that the cumulative genetic effects of serotonergic polymorphisms contribute to individual differences and dynamic processes in attachment dimensions in emerging adults.

Sex Differences in the Relationship Between School Bullying Victimization and Complex Posttraumatic Stress Disorder: The Roles of Insecure Attachment

School bullying victimization is a highly concerning issue that can lead to a range of negative outcomes. Despite the research showing a significant association between bullying victimization and complex posttraumatic stress disorder (CPTSD), the internal mechanisms with its two components (i.e., posttraumatic stress disorder symptoms [PTSD] and disorders of self-organization symptoms [DSO]) remain unclear. Previous studies have indicated that attachment style may influence the development of CPTSD symptoms and that there may be sex differences in attachment styles. Thus, the present study aims to examine the mediating role of insecure attachment between school bullying victimization and CPTSD symptoms in males and females. The study assessed bullying victimization, attachment orientation, and CPTSD (i.e., PTSD symptoms and DSO symptoms) symptoms in 675 college students (65.2% females; Mage = 19.6, SD = 1.34) from China who had reported bullying experiences at two different time points, 6 months apart. For females, school bullying victimization predicted PTSD and DSO symptoms through attachment anxiety and only predicted DSO symptoms through attachment avoidance. For males, we found that school bullying victimization predicted PTSD symptoms through attachment avoidance. These findings suggest that attachment is critical in understanding how school bullying victimization may lead to CPTSD symptoms among individuals of different sexes.

The association between COVID-19-related stressors and mental health outcomes for survivors of past interpersonal and non-interpersonal trauma

The mental health difficulties of trauma survivors during the COVID-19 pandemic have been under-reported. This study explored the moderating role of trauma history and trauma type (interpersonal and non-interpersonal) in the association between COVID-19-related stressors and depression, anxiety, and stress. A sample of n = 321 participants ages 19 to 71 (M = 36.63, SD = 10.36) was recruited from across the United States through MTurk. Participants reported the number of COVID-19-related stressors, trauma history and psychological symptoms. Hierarchical multiple regression analyses, controlling for age, race, ethnicity, gender, education, and income levels, were used to determine (a) whether COVID-19-related stressors are associated with adverse mental health outcomes; (b) whether trauma history and (c) trauma type moderated this association. Results revealed significant interactions; for those with a trauma history, exposure to COVID-19-related stressors was associated with higher levels of depression (β = .21, p < .05) and anxiety (β = .19, p < .05). For those with a history of interpersonal trauma specifically, COVID-19-related stressors were associated with depression (β = .16, p < .05) more so than for those without a trauma history. These findings highlight the vulnerability of trauma survivors to the unprecedented COVID-19-related stress.

Trauma exposure and eating disorders: Results from a United States nationally representative sample

OBJECTIVE

Sexual assault, child abuse, and combat have been linked to eating disorders (EDs). However, noninterpersonal trauma is relatively understudied, and therefore it is unknown whether noninterpersonal trauma is associated with EDs. Furthermore, most previous studies do not account for multiple trauma exposures, or the relative association of traumatic events with EDs in the same statistical model.

METHOD

Multinomial regression was used to examine the association of lifetime ED diagnosis (anorexia nervosa [AN], bulimia nervosa [BN], binge eating disorder [BED]) with trauma type (sexual interpersonal, other interpersonal, war/combat, and noninterpersonal) in a nationally representative dataset of US adults in bivariate and multivariable (i.e., with all trauma types) models.

RESULTS

Sexual interpersonal trauma was significantly positively associated with AN and BED in bivariate and multivariable models. In the multivariable model, only BED was found to be equally associated with sexual interpersonal, other interpersonal, and noninterpersonal trauma.

DISCUSSION

These results indicate a strong positive association between sexual trauma and EDs, even when controlling for experiences of other trauma events. Future research should examine longitudinal mediators between trauma and EDs, especially sexual trauma, to identify what factors may explain this relationship.

PUBLIC SIGNIFICANCE STATEMENT

Individuals with eating disorders often experience traumatic events but it is unclear whether specific trauma types are more or less common in this population. This study found that only events such as rape and sexual assault are associated with anorexia nervosa, but that most trauma types are associated with binge eating disorder. Therefore, the relationship between trauma and binge eating disorder may function differently than other eating disorders.

Insecure Attachment to Parents and PTSD among Adolescents: The Roles of Parent-Child Communication, Perceived Parental Depression, and Intrusive Rumination

Based on attachment theory and a social-cognitive model of posttraumatic stress disorder (PTSD), this study examined the roles of parent-child communication, perceived parental depression, and intrusive rumination in the association between insecure attachment to parents and PTSD among adolescents following the Jiuzhaigou earthquake. In this study, 620 adolescents were recruited to complete self-report questionnaires. The results showed that the direct association between anxious attachment and PTSD was significant, but that between avoidant attachment and PTSD was non-significant. In addition, both anxious and avoidant attachment had indirect associations with PTSD via the mediating effects of parent-child communication openness and problems, perceived parental depression, and intrusive rumination. However, the specific paths between anxious and avoidant attachment and PTSD were different. The findings indicated that insecure attachment among adolescents following the earthquake was predictive for their PTSD, and the mechanisms underlying the association between anxious attachment and PTSD and the association between avoidant attachment and PTSD were distinct. To alleviate PTSD, more attention should be paid to improving the quality of parent-child communication for adolescents with avoidant attachment to parents, and to reducing negative cognition in adolescents with anxious attachment.

Does attachment predict the outcome of cognitive processing therapy for posttraumatic stress disorder in adolescent patients with interpersonal traumatization?

The attachment has emerged as a significant predictor of psychotherapy outcome. However, studies on trauma-focused treatments and adolescent samples are sparse. We analyzed the data of 43 adolescents and young adults (aged 14-21 years) with clinically relevant abuse-related posttraumatic stress disorder (PTSD) who were undergoing developmentally adapted cognitive processing therapy (D-CPT) within a multicenter, randomized clinical trial (German Clinical Trials Register; identifier: DRKS00004787). Besides clinician-rated posttraumatic stress symptoms (PTSS), attachment-related (AR) anxiety and AR avoidance were assessed using self-reports before and after treatment as well as at three-month and six-month follow-ups. Baseline attachment did not predict any changes in PTSS severity. Averaging across all assessment points, overall higher posttraumatic avoidance was associated with greater baseline AR avoidance in D-CPT. In terms of change in attachment during the trial, a greater reduction of attachment insecurities was associated with a greater reduction of PTSS severity. Results are compared with those of the control group, a wait-list condition with treatment advice (WL/TA; N = 42). AR anxiety was more often a significant variable in the models in WL/TA, whereas AR avoidance was in D-CPT. Our study does furnish initial insights into the role of attachment during trauma-focused treatment with abused adolescents and young adults.Trial registration: German Clinical Trials Register identifier: DRKS00004787.

Relationships among non-interpersonal and interpersonal trauma types, posttraumatic stress, and posttraumatic growth

METHODS

Adults seeking behavioral health or medical treatment (N = 158) were recruited from a community healthcare agency and a residential support program in the southeastern United States.

RESULTS

Individuals who reported interpersonal trauma had significantly higher total PTS severity and symptom clusters. No significant difference was found in perceived PTG based on trauma type. No significant curvilinear relationship between PTS and perceived PTG was found. A significant negative linear relationship was observed between PTS and perceived PTG for non-interpersonal trauma, but not interpersonal trauma.

CONCLUSION

Trauma type may influence the PTS and perceived PTG relationship and, while associated with PTS, seems less important to reporting of perceived PTG.

Understanding the impact of attachment insecurity on PTSD symptoms among male Veterans and military personnel

Attachment insecurity (i.e., attachment anxiety and attachment avoidance) has been found to contribute to PTSD symptom severity in Veterans. However, little is known of the unique contribution of attachment insecurity on individual PTSD symptom clusters. In a community sample of 106 combat-deployed Veterans, active duty service members, and reservists, this study examined: (1) the relationships between childhood family experience, combat experience, attachment insecurity, and PTSD symptom clusters, and (2) the influence of attachment insecurity on PTSD symptom clusters. Results revealed significant correlations between attachment anxiety and all PTSD symptom clusters (rs = .22 -.43) and attachment avoidance and PTSD symptom clusters, except the avoidance cluster (rs = .21 -.36). Four multiple regression analyses were employed to address the second study aim. Childhood family experiences predicted negative alterations in cognitions and mood (β = -.30) and alterations in arousal and reactivity (β = -.20). Further, combat experience significantly predicted each symptom cluster of PTSD (βs = .03 -.44). In the second step, attachment anxiety and attachment avoidance were added to each model. Attachment anxiety and attachment avoidance predicted negative alterations in cognitions and mood (βs = .22 and .35) and alterations in arousal and reactivity (βs = .27 and .17). Inconsistent with previous research, attachment insecurity did not predict symptoms of avoidance. These results highlight the impact of attachment among a diverse sample of trauma exposed individuals and may provide insights for clinical implications and therapeutic approaches when working with Veterans and military personnel high in attachment insecurity.

Exploring the impact of trauma type and extent of exposure on posttraumatic alterations in 5-HT1A expression

The long-term behavioral, psychological, and neurobiological effects of exposure to potentially traumatic events vary within the human population. Studies conducted on trauma-exposed human subjects suggest that differences in trauma type and extent of exposure combine to affect development, maintenance, and treatment of a variety of psychiatric syndromes. The serotonin 1-A receptor (5-HT1A) is an inhibitory G protein-coupled serotonin receptor encoded by the HTR1A gene that plays a role in regulating serotonin release, physiological stress responding, and emotional behavior. Studies from the preclinical and human literature suggest that dysfunctional expression of 5-HT1A is associated with a multitude of psychiatric symptoms commonly seen in trauma-exposed individuals. Here, we synthesize the literature, including numerous preclinical studies, examining differences in alterations in 5-HT1A expression following trauma exposure. Collectively, these findings suggest that the impact of trauma exposure on 5-HT1A expression is dependent, in part, on trauma type and extent of exposure. Furthermore, preclinical and human studies suggest that this observation likely applies to additional molecular targets and may help explain variation in trauma-induced changes in behavior and treatment responsivity. In order to understand the neurobiological impact of trauma, including the impact on 5-HT1A expression, it is crucial to consider both trauma type and extent of exposure.

The links between adult attachment and post-traumatic stress: A systematic review

PURPOSE

The theory of attachment has informed our understanding of survival and well-being throughout the lifespan. There is a growing interest in the relationship between attachment and symptoms of post-traumatic stress (PTS). Emerging evidence points to important links between attachment and PTS, yet current theoretical and clinical understandings of PTS symptoms and attachment remain relatively disparate. The current systematic review aimed to synthesize, describe, and critique evidence demonstrating the links between attachment and PTS in adults. It also aimed to explore whether the relationship between attachment and PTS differs according to the nature of the traumatic event.

METHODS

Searches were conducted using PsycINFO, the Cochrane Library, Medline, and Google Scholar to identify empirical studies focusing on PTS in adults.

RESULTS

Twenty-one papers were identified. Attachment was shown to have moderating and mediating influences on the relationship between trauma and PTS. This varied according to the type of trauma, and how symptoms of PTS were reported across the different attachment styles. Methodological rigour varied across studies. Clinical and research implications are discussed, including the consideration of attachment security in assessment and formulation.

CONCLUSIONS

Although findings were mixed, this review suggests that there is an important link between attachment and PTS. It supports the current emerging evidence demanding the development of a more unified theoretical framework for attachment, types of trauma, and symptoms of PTS.

PRACTITIONER POINTS

The findings discussed in this review have important implications for the treatment of PTS symptoms. Consideration of attachment styles in formulations is likely to inform treatment plans. There is increasing evidence to suggest that assessing and accounting for attachment style in therapy may improve the chances of successful treatment.

Understanding posttrauma reactions within an attachment theory framework

The purpose of this paper is to review recent research on posttrauma reactions (i.e., posttraumatic stress disorder [PTSD] symptoms and self-reported posttraumatic growth [PTG]) using attachment theory as a framework. Attachment orientations are significantly related to PTSD symptoms: insecure attachment orientations (particularly attachment anxiety) are positively associated with PTSD symptoms whereas attachment security is negatively associated with PTSD symptoms. Although associations appear to be reciprocal, research typically focuses on insecure attachment orientations predicting PTSD symptoms and the possible mechanisms of those relations, particularly a lack of social support. Some trauma characteristics (e.g., trauma severity) also appear to moderate the association between attachment and PTSD symptoms. Research on attachment orientations and PTG, however, has yielded mixed results. More rigorous methods are needed to better understand the role of attachment orientations in actual growth from pre to post-trauma.
