Patterns of suicide ideation across eight countries in four continents during the COVID-19 pandemic era: repeated cross-sectional study

Nightmare frequency is a risk factor for suicidal ideation during the COVID-19 pandemic

The association between nightmare frequency (NMF) and suicidal ideation (SI) is well known, yet the impact of the COVID-19 pandemic on this relation is inconsistent. This study aimed to investigate changes in NMF, SI, and their association during the COVID-19 pandemic. Data were collected in 16 countries using a harmonised questionnaire. The sample included 9328 individuals (4848 women; age M[SD] = 46.85 [17.75] years), and 17.60% reported previous COVID-19. Overall, SI was significantly 2% lower during the pandemic vs. before, and this was consistent across genders and ages. Most countries/regions demonstrated decreases in SI during this pandemic, with Austria (-9.57%), Sweden (-6.18%), and Bulgaria (-5.14%) exhibiting significant declines in SI, but Italy (1.45%) and Portugal (2.45%) demonstrated non-significant increases. Suicidal ideation was more common in participants with long-COVID (21.10%) vs. short-COVID (12.40%), though SI did not vary by COVID-19 history. Nightmare frequency increased by 4.50% during the pandemic and was significantly higher in those with previous COVID-19 (14.50% vs. 10.70%), during infection (23.00% vs. 8.10%), and in those with long-COVID (18.00% vs. 8.50%). The relation between NMF and SI was not significantly stronger during the pandemic than prior (rs = 0.18 vs. 0.14; z = 2.80). Frequent nightmares during the pandemic increased the likelihood of reporting SI (OR = 1.57, 95% CI 1.20-2.05), while frequent dream recall during the pandemic served a protective effect (OR = 0.74, 95% CI 0.59-0.94). These findings have important implications for identifying those at risk of suicide and may offer a potential pathway for suicide prevention.

Mental health of Canadian youth: A systematic review and meta-analysis of studies examining changes in depression, anxiety, and suicide-related outcomes during the COVID-19 pandemic

OBJECTIVES

This systematic review and meta-analysis aims to describe Canadian youth mental health during the COVID-19 pandemic, focusing on changes in anxiety and depressive symptoms and suicidality.

METHODS

We searched four databases up to February 2023 for longitudinal or repeated cross-sectional studies reporting on changes in depressive and anxiety symptoms, suicidality, or related services utilization among young people under 25 years old residing in Canada during the COVID-19 pandemic. Random-effects meta-analyses were performed for studies comparing depressive and anxiety symptoms from before to during the first, second, and third COVID-19 waves (up to June 2021), and between COVID-19 waves. Other studies were described narratively. Risk of bias was assessed using an adapted Joanna Briggs Institute Checklist.

SYNTHESIS

Of the 7916 records screened, 35 articles met inclusion criteria for this review. Included studies were highly heterogeneous in design, population, and type of change investigated, and many had a high risk of bias. The meta-analyses found that depressive symptoms worsened minimally from pre-pandemic to wave 1 but returned to pre-pandemic levels by wave 2. Anxiety symptoms were broadly comparable from pre-pandemic to waves 1 and 2 but worsened from waves 1 to 3 and from pre-pandemic to wave 1 for girls. The narrative review included several studies that provided inconclusive evidence of increases in services utilization.

CONCLUSION

The current evidence is limited and highly heterogeneous, making it insufficient to draw definitive conclusions regarding the short- to medium-term impact of the pandemic on youth mental health in Canada. Obtaining better mental health surveillance among Canadian youth is imperative.

A Systematic Review on the Mental Health Status of Patients Infected With Monkeypox Virus

Objectives

This study aims to extract and summarize the literature on the mental health status of patients with monkeypox.

Methods

This review was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using different databases and publishers such as Scopus, Sage, ScienceDirect, PubMed, BMJ, Wiley Online Library, Wolters Kluwer OVID-SP, and Google Scholar. The literature review was based on monkeypox and mental health. The year of publication was 2021-2023, during the monkeypox disease period. Data were extracted from opinions, editorials, empirical studies, and surveys.

Results

Based on the literature related to the mental status of patients with monkeypox, the following themes and subthemes were identified: anxiety and depression, self-harm and suicidal tendencies, neuropsychiatric symptoms, mental health, social stigma, sex workers, vaccination, and stress-related diseases.

Conclusion

A review of monkeypox virus infection studies reveals that 25%-50% of patients experience anxiety and depression due to isolation, boredom, and loneliness. Factors such as infected people, a lack of competence among healthcare professionals, and shame over physical symptoms exacerbate mental insults. The implications of society include increased self-harm, suicide, low productivity, fear of stigmatization, and transmission of infection.

Dynamically adjustable SVEIR(MH) model of multiwave epidemics: Estimating the effects of public health measures against COVID-19

The COVID-19 pandemic was characterized by multiple subsequent, overlapping outbreaks, as well as extremely rapid changes in viral genomes. The information about local epidemics spread and the epidemic control measures was shared on a daily basis (number of cases and deaths) via centralized repositories. The vaccines were developed within the first year of the pandemic. New modes of monitoring and sharing of epidemic data were implemented using Internet resources. We modified the basic SEIR compartmental model to include public health measures, multiwave scenarios, and the variation of viral infectivity and transmissibility reflected by the basic reproduction number R0 of emerging viral variants. SVEIR(MH) model considers the capacity of the medical system, lockdowns, vaccination, and changes in viral reproduction rate on the epidemic spread. The developed model uses daily infection reports for assessing the epidemic dynamics, and daily changes of mobility data from mobile phone networks to assess the lockdown effectiveness. This model was deployed to six European regions Baden-Württemberg (Germany), Belgium, Czechia, Lombardy (Italy), Sweden, and Switzerland for the first 2 years of the pandemic. The correlation coefficients between observed and reported infection data showed good concordance for both years of the pandemic (ρ = 0.84-0.94 for the raw data and ρ = 0.91-0.98 for smoothed 7-day averages). The results show stability across the regions and the different epidemic waves. Optimal control of epidemic waves can be achieved by dynamically adjusting epidemic control measures in real-time. SVEIR(MH) model can simulate different scenarios and inform adjustments to the public health policies to achieve the target outcomes. Because this model is highly representative of actual epidemic situations, it can be used to assess both the public health and socioeconomic effects of the public health measures within the first 7 days of the outbreak.

Comparative analysis of the effect of interactive audio-visual based art therapy and music therapy in reducing suicidal ideation among school children who survived abduction

This study looked at how exposure to interactive TV-based music and art therapy could assist in reducing suicidal thoughts of secondary school female children who survived abduction in Nigeria. A quasi-experiment was carried out in three randomly selected secondary schools in Northern Nigeria. The study sample comprised 470 students divided into three groups to form control group 235, art therapy group 118 and music therapy group 117. Results suggest that participants exposed to interactive TV-based art therapy and music therapy reported a lower score for suicidal ideation compared to the control group that was not exposed to any form of therapy aside from routine clinic checkups. Specifically, those exposed to interactive TV-based art therapy reported a lesser suicidal ideation score than the music and the control group. We recommend the introduction of interactive TV-based music therapy and art therapy in reducing suicidal ideation among children that survived kidnapping in Nigeria.

Increased psychological distress among young people before and during the fifth wave of COVID-19 after two years of pandemic in Hong Kong: a 6-month longitudinal study

BACKGROUND

Despite over two years of COVID-19 worldwide, the outbreak of the Omicron variant has given rise to an unprecedented surge of infection with diverse lockdown measures implemented globally. Whether the emergence of a new wave of COVID-19 could further affect mental health in the population after nearly two years of the pandemic remains to be addressed. Furthermore, whether changes in smartphone overuse behaviours and physical activity - both of which are particularly relevant to young people - would together contribute to changes in distress symptoms during this wave of COVID-19 was also examined.

METHODS

A total of 248 young people from an ongoing household-based epidemiological study in Hong Kong who completed their baseline assessments prior to the Omicron variant outbreak, i.e., fifth wave of COVID-19 (July-November 2021), were invited for a 6-month follow-up study during this wave of infection (January-April 2022) (mean age = 19.7 years, SD = 2.7; 58.9% females). At both time points, levels of global distress symptoms, perceived stress, smartphone overuse, frequency of engagement in vigorous physical activity, and other potential risk and protective factors were assessed.

RESULTS

The proportion of young people presenting moderate-to-severe distress (6-item Kessler Psychological Distress Scale ≥ 5) significantly increased from 45.6 to 54.4% during the fifth wave of COVID-19 (p < 0.010). Significantly increased levels of smartphone overuse and reduced days of vigorous physical activity were also observed during the fifth wave. Notably, increased smartphone overuse and reduced physical activity both additively and interactively contributed to elevated distress at 6 months, even after accounting for demographic characteristics, psychiatric history, childhood adversity, as well as baseline distress symptoms, resilience, and recent personal stressors.

CONCLUSIONS

The findings suggest that the emergence of a new wave of COVID-19, specifically the Omicron outbreak, can further aggravate mental distress even after a protracted period of the pandemic. Awareness of the dynamic nature of COVID-19 is necessitated to address the pressing mental health needs of populations. Supporting young people in healthier patterns of smartphone use and physical activity can be helpful.

The COVID Psychosocial Impacts Scale: A Reliable and Valid Tool to Examine the Psychosocial Impacts of the COVID-19 Pandemic

This paper reports on the development and validation of the COVID Psychosocial Impacts Scale (CPIS), a self-report measure that comprehensively examines both positive and negative psychosocial impacts from the COVID-19 pandemic. This is the first part of the program of work in which the CPIS was administered and compared with a measure of psychological distress (Kessler Psychological Distress Scale, K-10) and wellbeing (World Health Organization Well-Being Index, WHO-5). The data were obtained online in 2020 and 2022 at two distinct time points to capture different exposures to the pandemic in the New Zealand population to a non-representative sample of 663 and 687 adults, respectively. Two hundred seventy-one participants took part in both surveys. Findings indicate a unidimensional structure within CPIS subscales and inter-relatedness among CPIS stress-related subscales. The scatter plots and correlation matrix indicate CPIS having a positive moderate correlation with K10 and a negative moderate correlation with WHO-5, indicative of construct validity. The paper outlines contextual factors surrounding CPIS development and makes suggestions for future iterations of CPIS. Further work will examine its psychometric properties across cultures.

The Effect of Herbal Medicine on Suicidal Behavior: A Protocol for Systematic Review and Meta-Analysis

Suicide is an important social and medical problem worldwide, including in countries that use traditional East Asian medicine (TEAM). Herbal medicine (HM) has been reported to be effective against several suicide-related conditions. This systematic review aimed to investigate the efficacy and safety of HM in reducing suicidal behavior including suicidal ideation, attempts, or completed suicide. We conduct a comprehensive search in 15 electronic bibliographic databases from inception to September 2022. All types of prospective clinical studies-including randomized controlled clinical trials (RCTs)-involving HM without or with routine care are included. The primary outcomes of this review are validated measures of suicidal ideation including the Beck scale for suicidal ideation. The revised Cochrane's risk of bias tool and other tools including the ROBANS-II tool are used to assess the methodological quality of RCTs and non-RCTs, respectively. A meta-analysis is performed using RevMan 5.4 in cases of homogeneous data from controlled studies. The results of the systematic review provide high-quality evidence to determine the efficacy and safety of HM for suicidal behavior. Our findings are informative for clinicians, policymakers, and researchers, aimed at reducing suicide rates, especially in countries that use TEAM.

Suicide Attempts Assisted By Firefighters According to Traumatic Brain Injury

Studies worldwide have reported increasing trends in suicides and attempts during the pandemic. The literature shows that improving surveillance and monitoring of suicide and attempts requires broad multisectoral prevention strategies. In Brazil, the São Paulo State Fire Department (CBPMESP) makes up the emergency response team for suicide and suicide attempted calls and public emergencies. Given this context, this paper sought to describe the characteristics of suicide attempts assisted by the CBPMESP according to traumatic brain injury (TBI), between 2018 and 2020, measured by the Glasgow Coma Scale (GCS). For this purpose, a descriptive study of 6,582 suicide attempts attended by CBPMESP was carried out. The factors associated with trauma brain injury according to the Glasgow Coma Scale (dependent variable) were analyzed by a multinomial regression model. Results show a significant increase of 8.0% (p = 0.039) in the number of calls responded by CBPMESP between 2018 and 2020. Men presented a higher prevalence of more violent methods for suicide attempts, namely firearms and hanging, followed by severe TBI; in women, severe TBI occurred mostly by hanging. Despite the increase in fatal suicide attempts during the pandemic, time to attend to victim acted as a protective factor for preventing severe TBI in men and women.

Connectedness in the time of COVID-19: Reddit as a source of support for coping with suicidal thinking

The COVID-19 pandemic is adversely impacting suicidality at a population level, with consequences resulting from a variety of pandemic-driven disruptions, including social activities and connectedness. This paper uses a single case study design to explore how members of the Reddit r/COVID19_support community create a sense of connectedness among those who have suicidal thoughts due to the pandemic. Data were gathered from posts to the r/COVID19_support subreddit forum from February 2020 through December 2020. The second step of Klonsky and May's (2015) Three-Step Theory (3ST) of suicide, connectedness as a key protective factor, was used as the theoretical framework. This study explored r/COVID19_support's constructed environment, users' dialogical interactions, and the four primary tenets of connectedness as proposed by Klonsky and May - Purpose and Meaning, Relationships, Religiosity, and Employment. Findings demonstrate a deep sense of connectedness for online community members. Relationships and Purpose and Meaning featured as the most salient sources of connectedness within this subreddit, whereas Religiosity was rarely discussed, and Employment was often spoken of in negative terms (i.e., creating mental distress, rather than facilitating connectedness). Contributors' responses offered various opportunities for connectedness both on- and off-line. Safe online spaces, such as r/COVID19_support, can serve as a protective factor amid suicidality, facilitating connectedness, and thereby helping to curtail suicidal thoughts from advancing to suicidal actions. This subreddit and similar online spaces can benefit specific populations who may otherwise find it challenging to access services or who wish to remain anonymous.

A Survey on Physiological Signal-Based Emotion Recognition

Physiological signals are the most reliable form of signals for emotion recognition, as they cannot be controlled deliberately by the subject. Existing review papers on emotion recognition based on physiological signals surveyed only the regular steps involved in the workflow of emotion recognition such as pre-processing, feature extraction, and classification. While these are important steps, such steps are required for any signal processing application. Emotion recognition poses its own set of challenges that are very important to address for a robust system. Thus, to bridge the gap in the existing literature, in this paper, we review the effect of inter-subject data variance on emotion recognition, important data annotation techniques for emotion recognition and their comparison, data pre-processing techniques for each physiological signal, data splitting techniques for improving the generalization of emotion recognition models and different multimodal fusion techniques and their comparison. Finally, we discuss key challenges and future directions in this field.

Time series analysis of the suicide attempts assisted by firefighters from 2017 to 2021 in São Paulo, Brazil

OBJECTIVE

This study aimed to analyze the time trends of suicide attempts assisted by the Fire Department of the Military Police of the State of São Paulo (Corpo de Bombeiros da Polícia Militar do Estado de São Paulo - CBPMESP) from 2017 to 2021, between sexes.

METHODS

This is an ecological study of 11,435 suicide attempts assisted by CBPMESP calls from January 2017 to December 2021. Three seasonal auto-regressive integrated moving average with exogenous (SARIMAX) models were adjusted considering total population, only men, and only women.

RESULTS

The total occurrences of suicide attempts were stationary in the prepandemic period but had an increased growth pattern after the pandemic began. This trend was higher among men, due to (1) lower assistance of suicide attempts during early pandemic than in the prepandemic period and (2) significant increased assistance after the beginning of vaccination against COVID-19, followed by a decrease, but with a tendency to increase, in the long-term pandemic.

CONCLUSION

Our results indicate a growth in the long-term suicide attempts during COVID-19. The beginning of vaccination was not considered significant in the reduction of CBPMESP attendances. These results corroborate the need for a multisectoral national suicide prevention strategy to mitigate the effects of the pandemic on mental health in the State of São Paulo.

Resilience and Wellbeing Strategies for Pandemic Fatigue in Times of Covid-19

The COVID-19 pandemic is truly one of the greatest collective health crises in history which have altered our life and living. For years, people have felt fatigued from following public health directives such as social distancing, wearing masks, washing hands frequently, and working or studying remotely without in-person interactions. In this paper, we explore strategies for resilience and wellbeing which can mitigate pandemic-caused stress and behavioural fatigue. We start with individual level strategies including reworking stress appraisals, the importance of psychological flexibility, reducing loneliness through adaptive online platform use, optimizing familial relationships when living in close quarters for a prolonged period, reducing symptoms of burnout and using adaptive distractions, using specific evidence-based resilience strategies. We discuss specific considerations which tap on our shared identities and shared responsibilities which can enhance a sense of community, especially for individuals from marginalized backgrounds and how suicide risks can be minimized.
