Purpose: Post-traumatic stress disorder (PTSD) is a common mental health problem but it is often unrecognized in health care and social service settings. Reliable and valid measures are important for practitioners to screen for PTSD in the Chinese context. This study developed and pilot tested a Chinese version of the PTSD Checklist for DSM-5 (PCL-5). Methods: The reliability and validity of the Chinese version of the PCL-5 were evaluated in a sample of N = 56 adult psychiatric patients in Taiwan. Online methods were used to facilitate the research process. Results: The Chinese version of the PCL-5 is internally consistent and is associated with trauma exposure and other mental health constructs. Participants with clinically diagnosed DSM-5 PTSD scored significantly higher on the PCL-5 than those without PTSD. The PCL-5 also had an acceptable discrimination performance in this sample. Discussion: Although the initial findings suggest that the PCL-5 is reliable and valid in this pilot study, caution should be taken when interpreting the results. The Chinese version of the PCL-5 may be a promising screening tool, but further psychometric evaluation is necessary.

Complex post-traumatic stress disorder (CPTSD) has recently been recognized as an official psychiatric diagnosis in ICD-11, after years of research and advocacy in the field. It has been suggested that dissociative symptoms are a major feature of CPTSD. This scoping review aimed to summarize the existing knowledge base on the relationship between dissociation and CPTSD, and to identify relevant research gaps. We searched the two largest and most widely used academic databases (i.e., the Web of Science and Scopus databases) and the ProQuest database and identified original studies published in English relevant to our research questions, namely: (1) Would CPTSD be associated with dissociative symptoms? 2) How common are dissociative symptoms among people with CPTSD? (3) What are the correlates of dissociative symptoms among people with CPTSD? In all, 26 studies were included. We found 10 studies which reported that people with CPTSD scored significantly higher on a dissociation measure than those without CPTSD, and 11 studies reported a positive correlation between CPTSD symptoms and psychoform/somatoform dissociation scores. While very few studies reported the prevalence and correlates of dissociative symptoms among people with CPTSD, there may be a considerable subgroup of people with CPTSD who have clinically significant levels of dissociative symptoms (e.g., 28.6–76.9%). Dissociation may also be associated with other comorbidities (e.g., DSM-IV Axis II features, shame, somatic symptoms) in people with CPTSD. We recommend that more studies are needed to investigate the prevalence of dissociative symptoms among people with CPTSD and examine how these symptoms are associated with other comorbid conditions and clinical needs in this vulnerable group.

Purpose: Pathological dissociation (PD) is an easily overlooked phenomenon in the mental health field. Standardized assessment is important for identifying dissociative symptoms and disorders. However, the use of PD measures in Chinese cultures needs investigation. This pilot study investigated the psychometric properties of three PD measures among Hong Kong Chinese. Methods: The psychometric properties of the Dissociative Experiences Scale-Taxon, the 5-item Somatoform Dissociation Questionnaire, and the Self-Report Version of the Dissociative Disorders Interview Schedule (SR-DDIS) were evaluated using online methods in Hong Kong. Results: The PD measures exhibited adequate to excellent internal consistency. The PD measures were negatively related to family support and can discriminate between participants with and without self-reported childhood abuse. There was excellent agreement between the online SR-DDIS results and the clinical diagnoses for presence of any dissociative disorder (DD) versus no DD. The DDs group scored significantly higher on PD measures than the depression group and the college student group. Discussion: The initial findings suggest that PD can be assessed online in Hong Kong. Further investigation is necessary.

Population aging is a major concern worldwide. Active aging should be promoted by increasing the social participation of older adults and enabling them to remain involved in the community. Research has demonstrated the utility of digital resources for addressing the needs of older adults, which include networking, entertaining, and seeking health-related information. However, the digital divide among older adults (i.e., the “gray digital divide”) is increasingly being recognized as a social problem that may be related to poor well-being. To obtain updated local data on the prevalence of Internet access and usage and their relationship with perceived well-being, we conducted telephone interviews with a random sample of 1018 older adults in Hong Kong from January to July 2021 (This research has received funding support from the Interdisciplinary Research Matching Scheme, Hong Kong Baptist University). We found that only 76.5% of the participants had Internet access at home, a mobile phone data plan, or both, whereas 36.3% had never used Internet services and 18.2% had no digital devices. A younger age, male gender, higher education level, living with others, and higher self-perceived social class were associated with material access to digital devices and everyday use of Internet services. Participants who accessed the Internet every day had higher levels of life satisfaction and self-rated physical and mental health than those who rarely or never used the Internet. Hierarchical multiple regression analysis revealed that digital skills were significantly associated with self-rated mental health even when controlling for demographic variables (including age, gender, education level, and self-perceived social class). This study contributes to the limited body of literature on the relationship between Internet use, digital skills, and perceived well-being. Our findings highlight the importance of addressing the digital divide even in cities with high penetration of information and communication technology, such as Hong Kong. We also discuss our insights into the use of timely interventions for older adults to address the gray digital divide.

Adverse childhood experiences (ACEs) have become a major concern in the mental health field. The literature suggests that ACEs could be associated with various mental health problems. Yet, ACEs require further investigation in Chinese cultures, especially in Hong Kong. Both the frequency of ACEs and their relationships with dissociation remain unknown in clinical settings in Hong Kong. In this study, we administered the Dissociative Experiences Scale (DES), the Somatoform Dissociation Questionnaire (SDQ) and the 10-item Adverse Childhood Experiences (ACEs) Questionnaire to 202 community mental health service users in Hong Kong. The frequency of ACEs and dissociation is reported and the trauma model of dissociation can be observed in this sample. Consistent with the Western literature, we found that ACEs are associated with mental health problems and that participants with childhood abuse and/or neglect report a significantly higher level of dissociation. While this study is preliminary, we suggest that ACEs and dissociation should receive more attention in the Chinese mental health field. Implications for practice are highlighted. Further studies are warranted.
