Trauma, Emotional Regulation, and Coping Styles in Individuals with and without Probable Dissociative Disorders in Hong Kong

Previous studies showed that dissociation and dissociative disorders (DDs) are prevalent and are associated with considerable individual and social consequences. There are ongoing debates regarding whether dissociation is a response to betrayal trauma across cultures and whether dissociation can be explained by maladaptive coping. Additionally, little is known about the clinical features of individuals with DDs in the Chinese context. This study aimed to investigate the relationship between trauma, emotional regulation, coping, and dissociation. We analyzed baseline data from a randomized controlled trial (N = 101). Participants with dissociative symptoms in Hong Kong completed self-report assessments. Structured interviews were also conducted subsequently. Participants with probable DDs reported more traumatic events (p = .009 to .017) and exhibited significantly higher levels of dysfunctional coping (p < .001) compared to those who reported dissociative symptoms but did not have a DD. Dissociative symptoms were more strongly associated with betrayal trauma than with non-betrayal trauma. Among different emotion regulation and coping strategies, dysfunctional coping was the only significant factor associated with dissociative symptoms (β = .309, p = .003). Dysfunctional coping was a statistically significant mediator that may explain the relationship between betrayal trauma and dissociative symptoms. Although other mediation paths are also possible and further longitudinal studies are required, our findings highlight the strong link between dysfunctional coping and dissociative symptoms and suggest that coping skills training should be incorporated into interventions for betrayal trauma survivors with dissociative symptoms. Additionally, this study provides evidence for the cross-cultural validity of the betrayal trauma theory. Further studies, however, are required.

COULD FAMILY WELL-BEING MODERATE THE RELATIONSHIP BETWEEN ADVERSE CHILDHOOD EXPERIENCES AND SOMATOFORM DISSOCIATION? A PRELIMINARY INVESTIGATION

The impacts of adverse childhood experiences (ACEs) have been well documented. One possible consequence of ACEs is dissociation, which is a major feature of post-traumatic psychopathology and is also associated with considerable impairment and health care costs. Although ACEs are known to be associated with both psychoform and somatoform dissociation, much less is known about the mechanisms behind this relationship. Little is known about whether social and interpersonal factors such as family environments would moderate the relationship between ACEs and somatoform dissociation. This paper discusses the importance of having a positive and healthy family environment in trauma recovery. We then report the findings of a preliminary study in which we examined whether the association between ACEs and somatoform dissociation would be moderated by family well-being in a convenience sample of Hong Kong adults (N = 359). The number of ACEs was positively associated with somatoform dissociative symptoms, but this association was moderated by the level of family well-being. The number of ACEs was associated with somatoform dissociation only when the family well-being scores were low. These moderating effects were medium. The findings point to the potential importance of using family education and intervention programs to prevent and treat trauma-related dissociative symptoms, but further investigation is needed.

A Preliminary Longitudinal Analysis of Symptom Management, Post-traumatic Stress, and Depressive Symptoms in Chinese Adults with Dissociative Symptoms

People with dissociative symptoms are generally poly-symptomatic and require high levels of healthcare resources. Post-traumatic stress disorder (PTSD) and depressive symptoms are two major disabling comorbid symptoms in people with dissociative symptoms. While the sense of control over symptoms may be associated with PTSD and dissociative symptoms, the interplay among these factors over time remains unexplored. This study examined the predictors of PTSD and depressive symptoms in people with dissociative symptoms. Longitudinal data from 61 participants with dissociative symptoms were analyzed. Participants completed self-report measures of dissociative, depressive, and PTSD symptoms and the sense of control over symptoms two times (T1 & T2) with an interval of over one month. PTSD and depressive symptoms were not transient or time-specific, but they persisted over time in our sample. Hierarchical multiple regression analyses revealed that, after controlling for age, treatment usage and baseline symptom severity, T1 symptom management scores (β = -.264, p = .006) negatively predicted T2 PTSD symptoms, while T1 PTSD symptoms (β = .268, p = .017) positively predicted T2 depressive symptoms. T1 depressive symptoms (β = -.087, p = .339) did not predict T2 PTSD symptoms. The findings highlight the importance of improving symptom management skills and treating comorbid PTSD symptoms when working with people with dissociative symptoms.

Childhood experiences and dissociation among high school students in China: Theoretical reexamination and clinical implications

BACKGROUND

Dissociation remains a controversial topic in terms of its prevalence, cross-cultural validity, and relationship with childhood trauma and adversities.

AIMS

This study investigated the prevalence of dissociative symptoms and probable dissociative disorders among Chinese high school students and tested the trauma model of dissociation.

METHODS

A total of N = 1,720 high school students completed standardized measures of positive and adverse childhood experiences (PCEs and ACEs), dissociation, depression, and anxiety.

RESULTS

The prevalence rates of dissociative symptoms and (probable) DSM-5 dissociative disorders (DDs) were 11.2% and 6.9%, respectively. Dissociation was a reliable construct (ICC = .682 to .752, p < .001) and was moderately correlated with general psychopathology (r = .424 with depressive symptoms, r = .423 with anxiety symptoms). Participants with a probable DD reported more ACEs, fewer PCEs, and more mental health symptoms than those without a probable DD. ACEs were significantly associated with dissociative symptoms (β = .107, p < .001) even after controlling for age, depressive, and anxiety symptoms. PCEs moderated the relationship between ACEs and dissociative symptoms.

CONCLUSIONS

This is the first report of the prevalence of dissociative symptoms and probable DSM-5 DDs among nonclinical children. We provide cross-cultural evidence that dissociation is a reliable and valid clinical phenomenon associated with psychopathology in children across cultures. The findings partly support the trauma model of dissociation. This study contributes to the limited literature on dissociation in children. It also offers empirical data to facilitate the ongoing controversy about (childhood) trauma and dissociation. Our findings imply that dissociation is cross-culturally associated with childhood adversities, but trauma is not the only, sufficient cause. Theoretical and clinical implications are discussed.

Is teacher violence a form of betrayal trauma? Relationship with mental health problems among young adults

BACKGROUND

Childhood trauma is one of the most preventable risk factors for mental health problems. Considering the substantial amount of time that young people spend in school during their early years, it is important to understand the potential impacts of teachers' behaviors on students' mental health.

OBJECTIVES

This study examined the relationship between exposure to teacher violence and mental health problems.

PARTICIPANTS AND SETTING

An international sample of young adults aged 18 to 24 (N = 283).

METHODS

Participants completed self-report measures of childhood trauma, exposure to teacher violence, depressive symptoms, post-traumatic stress, and alcohol misuse.

RESULTS

Exposure to teacher violence could be reliably and validly measured using the Teacher Violence Scale (TVS). Current mental health problems - including depressive symptoms, post-traumatic stress, and alcohol misuse - were associated with exposure to teacher violence during high school years, but not with childhood non-betrayal trauma.

CONCLUSIONS

Our findings expand the application of the betrayal trauma theory to school settings and point to the importance of preventing and managing teacher violence. It is important to provide more support and training to teachers and enhance monitoring measures in schools. More research on the prevalence and correlates of exposure to teacher violence is needed. We also provided first evidence supporting the reliability and validity of the English version of the TVS to facilitate future research.

Dissociative symptoms among community health service users in Hong Kong: a longitudinal study of clinical course and consequences

Background: Previous studies have demonstrated the high prevalence of dissociative symptoms and their association with considerable healthcare costs. However, there is a lack of studies that describe whether dissociative symptoms persist and lead to other clinical outcomes over time in the community.Objectives: This study investigated the persistence, predictors, and consequences of dissociative symptoms in the community.Methods: We analyzed longitudinal data in a sample of community health service users in Hong Kong (N = 173).Results: A relatively high proportion (63.6%) of participants with baseline dissociative symptoms continued to exhibit dissociative symptoms after approximately 9 months. Baseline non-betrayal trauma predicted subsequent dissociative symptoms (β = .141, p = .024). Participants with baseline dissociative symptoms were more likely to have received subsequent emergency mental health services (9.1% vs 0.7%, p = .005). Baseline dissociative symptoms significantly predicted subsequent post-traumatic symptoms (β = .165 to .191, p < .05) and difficulty in social and occupational participation (β = -.152 to -.182, p < .05) even after controlling for baseline scores, trauma exposure, and use of professional support. The predictive role of dissociative symptoms on subsequent disturbances in self-organization symptoms and social participation difficulty remained significant after applying the Bonferroni correction.Conclusions: This is one of the very few studies showing that dissociative symptoms are persistent to a certain degree and could predict other symptoms and subsequent impairments even in community settings. Factors that affect the trajectory of dissociative symptoms should be further investigated. Regular screening for dissociative symptoms is recommended. Considering its prevalence, persistence, and clinical and social consequences, dissociation should be given greater public health attention.

Persistence and clinical consequences of post-traumatic and dissociative symptoms in people with depressive symptoms: a one-year follow-up study

BACKGROUND

Recent studies found that post-traumatic and dissociative symptoms are common in people with depressive symptoms. Although a trauma-related subtype of depression has been proposed, little is known about the persistence and clinical consequences of these symptoms.

OBJECTIVE

This one-year follow-up study investigated the persistence and clinical consequences of post-traumatic and dissociative symptoms in people with depressive symptoms.

METHODS

We analyzed longitudinal data from an international sample of people self-reporting depressive emotions (N = 152) (mean Patient Health Questionnaire-9 score = 17.27; SD = 6.31).

RESULTS

More than half (58.4%) of participants with baseline post-traumatic stress disorder (PTSD) still met the criteria for PTSD after one year. Participants with dissociative symptoms at baseline were significantly more likely to report lifetime psychiatric hospitalization (31.2% vs 14.7%), past-year use of psychiatric hospitalization (10.4% vs 0%) and emergency services (16.9% vs 4%) than those without dissociative symptoms. All post-traumatic and dissociative symptom clusters were cross-sectionally (r = .286 to .528, p < .001) and longitudinally (r = .181 to .462, p < .001) correlated with depressive symptoms. A sense of current threat (β = .146, p < .05) and negative self-concept (β = .173, p < .05) at baseline significantly predicted depressive symptoms after one year.

CONCLUSIONS

These findings contribute to the increasing body of knowledge regarding the PTSD/dissociation-depression comorbidity. Given their persistence and clinical consequences, we recommend that post-traumatic and dissociative symptoms be regularly screened for in clinical settings. The existence of a possible trauma-related subtype of depression should receive more attention in both research and clinical practice.

Association Among Negative Life Events, Sense of Security, and Depressive Symptoms in Chinese Adolescents After the 2013 Ya'an Earthquake

OBJECTIVE

About a fourth of Chinese adolescents developed clinically significant depressive symptoms following a disaster. However, little is known about whether and how post-trauma negative life events and a sense of security are associated with depressive symptoms in this population. This study examined the psychological experiences of Chinese young people who had experienced the 2013 Ya'an earthquake in Sichuan, China.

METHODS

This cross-sectional study was conducted in 2019. A total of 693 Chinese middle school students completed a questionnaire that measured their level of depressive symptoms, trauma exposure, stressful life events, and sense of security.

RESULTS

Results of hierarchical multiple-regression analyses showed that the level of life stress from stressful life events was positively associated with the level of depressive symptoms (β = 0.416, P < 0.001) and the level of the sense of security was negatively associated with the level of depressive symptoms (β = -0.352, P < 0.001) when analysis controlled for age, gender, and trauma exposure.

CONCLUSIONS

These findings highlight the importance of considering the influence of life stressors and the sense of security in devising measures and strategies for the prevention of the manifestation of depression among young people, particularly those who were exposed to disasters.

Interpersonal stress mediates the relationship between childhood trauma and depressive symptoms: Findings from two culturally different samples

OBJECTIVE

Childhood trauma is associated with adulthood depressive symptoms, but very few studies explored potential social and interpersonal mediators behind this association. This study made the first attempt to test the potential mediating effects of interpersonal stress in the associations between childhood betrayal and non-betrayal trauma and depressive symptoms.

METHOD

We analyzed data in a sample of English-speaking adults from diverse backgrounds (from 19 different countries, mainly from Western countries) (N = 468). We then replicated and compared the results with those in another convenience sample of Chinese-speaking younger adults with different cultural backgrounds and mental health status (N = 205).

RESULTS

The results in both samples indicated that (1) childhood betrayal trauma had a stronger relationship with depressive symptoms than childhood non-betrayal trauma and that (2) interpersonal stress was a significant mediator in the relationship between childhood betrayal trauma and depressive symptoms, even when childhood non-betrayal trauma was included as a covariate. The indirect effect of childhood non-betrayal trauma on depressive symptoms through interpersonal stress was not consistent in two samples.

CONCLUSIONS

Our findings point to the importance of taking social and interpersonal contexts into account when investigating, preventing and managing depression in trauma-exposed populations. Early social interventions such as family interventions, interpersonal skills training and building social resources may have the potential to change the trajectory of the development of mental health problems in trauma survivors.

Examining the Volunteer Satisfaction Index - Chinese (VSI-C) among Chinese Adolescents in Hong Kong

Purpose: The purpose of this study was to validate an existing measure of The Volunteer Satisfaction Index - Chinese (VSI-C) using the sample of 1,046 secondary school students. Method: In this study, the factor structure of VSI-C was explored and reexamined with a sample of secondary school students in Hong Kong in order to ensure the scale to be psychometrically sound and applicable to diversified student populations. Results: The exploratory factor analysis revealed in this examination that a three-factor structure that differs from the model proposed by the scale developers and the version used in a number of previous studies. A revised 19-item scale was introduced after the confirmatory factor analysis was conducted. VSI-C would be a psychometrically sound measure in measuring volunteer satisfaction across different student populations. Discussion: Implications are discussed for assessing volunteer satisfaction, offering volunteer training and conducting future research on related topics.
