A Newly Developed Online Peer Support Community for Depression (Depression Connect): Qualitative Study

Characterizing Major Depressive Disorder (MDD) using alpha-band activity in resting-state electroencephalogram (EEG) combined with MATRICS Consensus Cognitive Battery (MCCB)

BACKGROUND

The diagnosis of major depressive disorder (MDD) is commonly based on the subjective evaluation by experienced psychiatrists using clinical scales. Hence, it is particularly important to find more objective biomarkers to aid in diagnosis and further treatment. Alpha-band activity (7-13 Hz) is the most prominent component in resting electroencephalogram (EEG), which is also thought to be a potential biomarker. Recent studies have shown the existence of multiple sub-oscillations within the alpha band, with distinct neural underpinnings. However, the specific contribution of these alpha sub-oscillations to the diagnosis and treatment of MDD remains unclear.

METHODS

In this study, we recorded the resting-state EEG from MDD and HC populations in both open and closed-eye state conditions. We also assessed cognitive processing using the MATRICS Consensus Cognitive Battery (MCCB).

RESULTS

We found that the MDD group showed significantly higher power in the high alpha range (10.5-11.5 Hz) and lower power in the low alpha range (7-8.5 Hz) compared to the HC group. Notably, high alpha power in the MDD group is negatively correlated with working memory performance in MCCB, whereas no such correlation was found in the HC group. Furthermore, using five established classification algorithms, we discovered that combining alpha oscillations with MCCB scores as features yielded the highest classification accuracy compared to using EEG or MCCB scores alone.

CONCLUSIONS

Our results demonstrate the potential of sub-oscillations within the alpha frequency band as a potential distinct biomarker. When combined with psychological scales, they may provide guidance relevant for the diagnosis and treatment of MDD.

Understanding the Impacts of Online Mental Health Peer Support Forums: Realist Synthesis

BACKGROUND

Online forums are widely used for mental health peer support. However, evidence of their safety and effectiveness is mixed. Further research focused on articulating the contexts in which positive and negative impacts emerge from forum use is required to inform innovations in implementation.

OBJECTIVE

This study aimed to develop a realist program theory to explain the impacts of online mental health peer support forums on users.

METHODS

We conducted a realist synthesis of literature published between 2019 and 2023 and 18 stakeholder interviews with forum staff.

RESULTS

Synthesis of 102 evidence sources and 18 interviews produced an overarching program theory comprising 22 context-mechanism-outcome configurations. Findings indicate that users' perceptions of psychological safety and the personal relevance of forum content are foundational to ongoing engagement. Safe and active forums that provide convenient access to information and advice can lead to improvements in mental health self-efficacy. Within the context of welcoming and nonjudgmental communities, users may benefit from the opportunity to explore personal difficulties with peers, experience reduced isolation and normalization of mental health experiences, and engage in mutual encouragement. The program theory highlights the vital role of moderators in creating facilitative online spaces, stimulating community engagement, and limiting access to distressing content. A key challenge for organizations that host mental health forums lies in balancing forum openness and anonymity with the need to enforce rules, such as restrictions on what users can discuss, to promote community safety.

CONCLUSIONS

This is the first realist synthesis of online mental health peer support forums. The novel program theory highlights how successful implementation depends on establishing protocols for enhancing safety and strategies for maintaining user engagement to promote forum sustainability.

"No man is an island": How Chinese netizens use deliberate metaphors to provide "depression sufferers" with social support

Objective

Online social support provides a way to positively influence depression sufferers. In the present study, we aim to analyze how social support in Chinese online depression communities is communicated through the lens of deliberate metaphor theory (DMT) to deepen the understanding of the under-researched complicated, emotionally laden, and culture-related concepts of this experience.

Methods

We collected data (n = 3546 comments) from the Warm Supporting section of the Depression Super Topic, a major Chinese online depression community on Weibo. The data were analyzed using a metaphorical analysis with the Metaphor Identification Procedure Vrije Universiteit and a thematic analysis.

Results

Our findings identify two themes: deliberate metaphors (DMs) of depression and DMs of social environment for depression sufferers. The former conceptualizes future expectations without depression (as rosy images; victorious battles; the beaten black dog); disorder (as subtle objects; subjective initiative events); depression sufferers (as valuable objects; important roles); and present life with depression (as optional events; spiritual practices; fragile objects). The latter conceptualizes social connection (as solid objects; nonessentials); individuals in the social environment (as energetic objects; vicious roles); and prejudice (as colored objects).

Conclusions

The findings suggest that DMs as important online social support resources, helping to express empathy and normalize depression with more common-sense, and non-judgmental concepts. Additionally, in DMs, Chinese netizens navigate the intricate intersection of medical and moral perspectives on depression and its recovery, leveraging both aspects to offer comprehensive social support. "Confucian-based" elements are embedded in culture-related social support expressions in DMs. In practice, our findings contribute to tailored and appropriate health interventions for depression.

Leveraging stylometry analysis to identify unique characteristics of peer support user groups in online mental health forums

Online peer support mental health forums provide an effective and accessible form of support, augmenting scarce clinical and face-to-face assistance. However, to enhance their effectiveness, it is essential to understand the unique characteristics of peer support user groups, and how they participate, contribute and communicate in these forums. This paper proposes and tests a novel approach that leverages stylometry analysis to uncover the unique characteristics of peer support user groups in such forums. Our approach identifies how each group empowers and supports other users, and what distinguishes them from others. The analysis shows that emotion-related words are crucial in identifying and distinguishing user groups based on their writing style. Comparative analysis of emotion expressions across user groups also uncovers the significance of emotional content in these forums in promoting mental well-being. Valued 'senior contributors' were more likely than all other groups including trained community guides to use a wide range of both positive and negative emotions in their posts. These findings have significant implications for improving the training of peer-mentors and moderators, scaling forum services, and improving guidelines for emotional expression among peer support users. Our approach presents an objective approach to differentiating the characteristics and communication patterns of valued senior contributors, mentors, and guides, enabling service providers to foster the kinds of communication that supports positive outcomes for distressed users.

Coping with depression: a narrative study of an online depression community in China

PURPOSE

The goal of this study was to explore the coping strategies of depression sufferers that have worked for them based on the study of an online depression community.

METHODS

We conducted a thematic narrative analysis of 120 stories posted by the members in the largest online depression community in China. MaxQDA version 18 was used to code the data, and the analytic approach was consistent with the category-centred approach of grounded theory.

RESULTS

The study found that the coping strategies mainly include self-reconciliation (e.g., perceiving/accepting feelings, accepting the present self, and holding hope for the future), actions (recreational activities, physical exercise, and engaging in volunteer work), addressing the stressors and symptoms (e.g., staying away from stressors, seeing the doctor), and seeking interpersonal support (e.g., seeking support from family, friends, and peers).

CONCLUSION

The findings revealed the coping strategies that were helpful and examined how they functioned for the affected members, which make up for the lack of attention to the individual experiences of depression sufferers in coping research. The findings also have practical implications for the related education and consultation, providing useful insights for doctors and patients. These ways of coping are based on depression sufferer' anonymous narratives, which can be convincing to clients.

The Development of Game-Based Digital Mental Health Interventions: Bridging the Paradigms of Health Care and Entertainment

Game elements are increasingly used to improve user engagement in digital mental health interventions, and specific game mechanics may yield therapeutic effects per se and thereby contribute to digital mental health intervention efficacy. However, only a few commercial game-based interventions are available. We suggest that the key challenge in their development reflects the tension between the 2 underlying paradigms, health care and entertainment, which have disparate goals and processes in digital development. We describe 3 approaches currently used to negotiate the 2 paradigms: the gamification of health care software, designing serious games, and purpose shifting existing entertainment games. We advanced an integrative framework to focus attention on 4 key themes in intervention development: target audience, engagement, mechanisms of action, and health-related effectiveness. On each theme, we show how the 2 paradigms contrast and can complement each other. Finally, we consider the 4 interdependent themes through the new product development phases from concept to production. Our viewpoint provides an integrative synthesis that facilitates the research, design, and development of game-based digital mental health interventions.

Evaluation of the Use of Digital Mental Health Platforms and Interventions: Scoping Review

BACKGROUND

The increasing use of digital mental health (DMH) platforms and digital mental health interventions (DMHIs) is hindered by uncertainty over effectiveness, quality and usability. There is a need to identify the types of available evidence in this domain.

AIM

This study is a scoping review identifying evaluation of the (1) DMH platform/s used; and (2) DMHI/s applied on the DMH platform/s.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guided the review process. Empirical studies that focused on evaluation of the use and application of DMH platforms were included from journal articles (published 2012-2022). A literature search was conducted using four electronic databases (Scopus, ScienceDirect, Sage and ACM Digital Library) and two search engines (PubMed and Google Scholar).

RESULTS

A total of 6874 nonduplicate records were identified, of which 144 were analyzed and 22 met the inclusion criteria. The review included general/unspecified mental health and/or suicidality indications (n = 9, 40.9%), followed by depression (n = 5, 22.7%), psychosis (n = 3, 13.6%), anxiety and depression (n = 2, 9.1%), as well as anxiety, depression and suicidality (n = 1, 4.5%), loneliness (n = 1, 4.5%), and addiction (n = 1, 4.5%). There were 11 qualitative studies (50%), 8 quantitative studies (36.4%), and 3 mixed-methods studies (n = 3, 13.6%). The results contained 11 studies that evaluated the DMH platform/s and 11 studies that evaluated the DMHI/s. The studies focused on feasibility, usability, engagement, acceptability and effectiveness. There was a small amount of significant evidence (1 in each 11), notably the (cost-)effectiveness of a DMHI with significant long-term impact on anxiety and depression in adults.

CONCLUSION

The empirical research demonstrates the feasibility of DMH platforms and DMHIs. To date, there is mostly heterogeneous, preliminary evidence for their effectiveness, quality and usability. However, a scalable DMHI reported effectiveness in treating adults' anxiety and depression. The scope of effectiveness may be widened through targeted strategies, for example by engaging independent young people.

The relationship between social capital and postpartum depression symptoms of lactating women in minority areas—A cross-sectional study from Guangxi, China

Background

Postpartum depression (PPD) is the most common mental illness affecting women during lactation, and good social capital is considered a protective factor. This study aimed to investigate PPD symptoms, and explore the relationships between social capital and PPD symptoms of lactating women in southwest minority areas in China.

Materials and methods

This cross-sectional study was conducted among 413 lactating women in Guangxi, China. Data were collected using the Edinburgh Postnatal Depression Scale and the Chinese version of the Social Capital Assessment Questionnaire. Hierarchical regression analysis was conducted to explore the factors influencing PPD symptoms, and a structural equation model was used to examine how social participation and cognitive social capital mediated PPD symptoms.

Results

The total prevalence of PPD symptoms (score > 12) was 16.46%, and that of mild depression symptoms (9–12 score) was 22.03%. Nine variables predicted PPD symptoms and explained 71.6% of the variance in the regression model: higher age, lack of medical security, fixed occupation, breastfeeding time, self-caregiver, maternity leave, social participation, social trust, and social reciprocity. Furthermore, cognitive social capital mediated the relationship between social participation and PPD symptoms, with a mediation effect rate was 44.00%.

Conclusion

The findings of this study highlight that social capital, support from family members, maternity leave, and medical insurance play protective roles in the PPD symptoms of lactating women. It is necessary to improve social capital as a key strategy for interventions for PPD symptoms, and active social participation activities are critical to reducing PPD symptoms among lactating women in minority areas.

Virtual social interaction and loneliness among emerging adults amid the COVID-19 pandemic

Many social activities moved online during the global COVID-19 pandemic, yet research investigating whether virtual social interactions facilitate social connectedness has been inconclusive. In this study, participants completed online questionnaires assessing objective social isolation, loneliness, mental health, and virtual social interactions. There was clear evidence for worsening mental health among emerging adults during the COVID-19 pandemic characterized by large increases in depressive symptoms (mean increase = 8.35, 95% CI [6.97, 9.73], t(118) = 118, p < .001), and large decrements in happiness (mean decrease = -0.71, 95% CI [-0.84, -0.57], t(118) = 10.09, p < .001) and social satisfaction (mean decrease = -0.81, 95% CI [-1.00,-0.62], t(115) = 8.28, p < .001) post-pandemic onset. In line with expectations, those living in larger households amid the pandemic reported lower levels of loneliness and higher levels of happiness. A negative association was found between household size (an index of objective social isolation) and loneliness, b = -3.01, t(79) = 2.60, p = .011, 95% CI [-5.32, -0.71], and a positive association was found between household size and happiness, b = 22.86, t(75) = 3.30, p = .001, 95% CI [9.06, 36.65]. However, contrary to expectations, there was no association between loneliness and frequency of virtual social interactions. There was also no association between frequency of virtual social interactions and either happiness or depression. More research investigating social connectedness in the context of virtual social interactions is warranted.

Pregnant women's coping strategies, participation roles and social support in the online community during the COVID-19

Pregnant women are experiencing enormous physical changes and suffering pregnancy-related losses, which may lead to depression symptoms during pregnancy. Given that the onslaught of COVID-19 had exacerbated pregnant women's anxiety because of disruptions in antenatal care and concerns regarding safe delivery, it is worth exploring how they obtain social support to cope with stress during COVID-19. Although many works have explored the impact of coping resources that people have on coping strategies, few studies have been done on the relationship between people's coping strategies and their acquisition of coping resources such as social support. To fill this gap, based on the stress and coping theory (SCT) and social penetration theory (SPT), this study investigates the impacts of pregnant women's different coping strategies on the acquisition of social support and the moderating role of the adverse impacts of COVID-19 and their online participation roles (support providers vs. support seekers) using the data of 814 pregnant women's online behavior from a parenting community in China1. Our study indicates that both women's superficial level disclosure and personal level disclosure positively affect online social support received. Moreover, self-disclosure about the adverse impacts of COVID-19 negatively moderates the relationship between personal level disclosure and social support received. Participation role positively moderates the relationship between personal level disclosure and social support received, but negatively moderates the relationship between superficial level disclosure and social support received. This paper makes theoretical contributions to the literature of SCT, SPT and the literature about social support in online communities.
