Positive mental health mediates the relationship between physical activity and suicide-related outcomes: a three-year follow-up study

Sex-related differences in the associations between wishing to die, grip strength, and physical activity: An analysis in European middle-aged and older adults

BACKGROUND

The desire to die among older adults has been reported in several European countries. This study aimed to investigate the associations between grip strength (GS) and the frequency of weekly moderate physical activity (MPA) with wish to die (WTD) in European middle-aged and older adults.

METHODS

A cross-sectional analysis was conducted with 39,377 participants (22,313 women) from 27 European countries, aged ≥50 years, responding to wave 8 of the SHARE project. GS was assessed for both hands by a dynamometer, WTD was obtained by asking: 'In the last month, have you felt that you would rather be dead?' from the 12-item EURO-D scale, and the weekly frequency of moderate physical activity (MPA) was self-reported.

RESULTS

Greater GS (per 1 unit) was associated with a 26 % to 55 % lower chances of WTD among men. Among women, a 1 kg increase in GS was associated with a 40 % to 70 % lower chance of WTD. MPA once a week or more than once a week (compared to MPA less than once a week) was associated with a 57 % and 58 % lower chance of WTD among men. Among women, MPA once a week or more than once a week (compared to MPA less than once a week) was associated with 44 % and 48 % lower odds of WTD.

CONCLUSION

GS was inversely associated with WTD, particularly in women. Engaging in MPA once a week showed a greater association with less WTD for both sexes than MPA more than once a week, particularly in men.

Four-year associations of wish-to-die trajectories with changes in the frailty of European citizens aged 50 and over

BACKGROUND

A death wish is a passive ideation about thoughts that suggest dying is better than continuing to live. We investigated the associations of different wish-to-die (WTD) trajectories with changes in frailty over a four-year period in European citizens aged 50 and over.

METHODS

A longitudinal analysis was conducted with 27,350 participants (13,921 women) from 17 European countries, all aged ≥50 years, who responded to waves 6 and 8 of the Survey of Health, Ageing, and Retirement in Europe (SHARE) project. WTD was assessed by asking, 'In the last month, have you felt that you would rather be dead?'. Frailty was measured using the SHARE-Frailty (SHARE-FI) questionnaire.

RESULTS

A significant effect of time on frailty was observed, with a medium effect size (p < 0.001, ηp2 = 0.08), as well as a significant time × group interaction with a medium effect size (p < 0.001, ηp2 = 0.12). Post hoc analysis revealed a 54.5 % increase in frailty for the continued non-WTD trajectory group over four years. The non-WTD to WTD trajectory group showed a 186.0 % increase in frailty, while the continued WTD group showed a 27.9 % increase in frailty. On the other hand, the group with a trajectory from WTD to non-WTD indicated a reduction in the index of 28.8 %.

CONCLUSIONS

Emerging WTD may be associated with increased frailty in older age. Conversely, frailty may be reduced among those who exchanged the passive idealization of dying for living.

Less smartphone and more physical activity for a better work satisfaction, motivation, work-life balance, and mental health: An experimental intervention study

Employees' work satisfaction and mental health are crucial for an organization's productivity. The current experimental study on employees (Ntotal = 278) from different professional sectors and workplaces in Germany investigated how to improve both by changes of daily non-work-related smartphone use time and physical activity time. For one week, the smartphone group (N = 73) reduced its daily smartphone use by one hour, the physical activity group (N = 69) increased its daily physical activity by 30 minutes, the combination group (N = 72) followed both interventions, the control group (N = 64) did not change its behavior. Online surveys assessed work-related and mental health-related variables at three measurement time points (baseline; post-intervention; two-week follow-up). The reduction of smartphone use time and the combination of both interventions increased work satisfaction, work motivation, work-life balance, and positive mental health significantly; experience of work overload and problematic smartphone use significantly decreased. All interventions decreased depressive symptoms and enhanced sense of control significantly. Following the present findings, a conscious and controlled reduction of non-work-related smartphone use time and its combination with more physical activity could improve employees' work satisfaction and mental health in the organizational context either as an addition to established training programs or as a separate time- and cost-efficient low threshold program.

The "Vicious Circle of addictive Social Media Use and Mental Health" Model

Social media use (SMU) is a significant part of many people's everyday life. Research around the globe describes an increase of addictive SMU tendencies since the COVID-19 outbreak. The present work combines available findings in the "Vicious Circle of addictive Social Media Use and Mental Health" model to explain how social media (SM) activity can contribute to the development of addictive tendencies, which consequences they have for mental health, and how to prevent them. Following the model, the interplay between the risk factors negative experiences caused by daily hassles and by unexpected global and traumatic events, SMU (dimension "quality"), and SM flow can directly contribute to addictive SMU through the "vicious circle". Time spent on SMU (dimension "quantity"), symptoms of depression and anxiety, and the personality trait narcissism contribute to the circle as moderators. Symptoms of stress, insomnia, and suicide-related outcomes are described as potential consequences of addictive SMU. Based on longitudinal intervention studies, a conscious reduction of SMU time and an increase of physical activity, as well as positive mental health and mindfulness are identified as protective factors that reduce the risk of addictive tendencies. The model contributes to a better understanding of addictive SMU. Implications of the model for future research and praxis, specifically for mental health programs and therapeutic treatment are discussed.

Positive mental health accounts for the relationship between insomnia symptoms and suicide-related outcomes

Insomnia symptoms have been shown to be associated with suicide ideation/behavior. However, the underlying mechanism is unclear and studies on protective factors that might mitigate the association between sleep-related problems and suicide ideation/behavior are largely missing. On this background the aim of the current study was to investigate, whether positive mental health (PMH) accounts for the association between insomnia symptoms and suicidal ideation/behavior. A total of 913 participants (72.2% women; age: M(SD) = 25.91 (7.08)) completed measures on insomnia symptoms, PMH and suicide ideation/behavior via an online survey. The results reveal a significant association between insomnia symptoms and PMH. Both variables were significantly linked to lifetime suicide ideation/behavior and 12-month suicide ideation. Moreover, the association between insomnia symptoms and suicide-related outcomes was significantly mitigated by PMH. The current findings complement previous studies on the association between insomnia symptoms and suicide ideation/behavior. Furthermore, they demonstrate that PMH can mitigate the risk of suicide-related outcomes. Therapeutic intervention targeting insomnia symptoms and fostering PMH might be useful in the prevention of suicide ideation/behavior.

Job Loss Due to COVID-19: A Longitudinal Study of Mental Health, Protective and Risk Factors

The COVID-19 pandemic had a devastating impact on unemployment, which-compounded by the additional stressors associated with the pandemic-had considerable mental health impact. The current study examined the trajectory of mental health amongst those experiencing pandemic-related job loss, alongside the impact of risk and protective factors. Data were obtained from 374 Australian participants who were allocated to a waitlist control arm of a randomised control trial. The outcome variables assessed at baseline and six-month follow-up consisted of depression, anxiety, and suicidality. The assessed risk and protective factors were age, gender, relationship status, education, exercise frequency, COVID-related stress, dispositional resilience, and coping self-efficacy. Re-employment by follow-up was used as a covariate. Overall, there were decreases in depression and anxiety symptoms, and partial evidence of decreased suicidality, demonstrating an apparent capacity for individuals to better cope with their circumstances over time. Demographics and exercise had no effect on changes in mental health. Those with high COVID-related stress, low resilience, and low coping self-efficacy had worse mental health at baseline, although exhibited significantly greater improvements in mental health over time. Obtaining re-employment by follow-up did not predict changes in mental health. The present results offer an optimistic picture of recovery for those experiencing pandemic-related job loss, even for those with the most substantial risk and severity. The likely protective role played by Australian social welfare policies over the course of the study is explored. Stress around one's broader sociocultural or economic circumstances, perceived resilience, and coping self-efficacy are valuable targets for intervention.

Beneficial and negative factors for the development of students’ well-being in educational context

Students’ school-related well-being (SWB) is of vital importance. Nevertheless, it is unclear how SWB develops in late adolescence, especially among students in high-achieving environments and which factors are associated with it. Based on a longitudinal dataset (T1: Grade 11, T2: Grade 12), we analyzed how SWB (school satisfaction, academic self-concept, stress experience, exam anxiety, peer satisfaction) develops and whether psychological needs (autonomy, competence, relatedness) and achievement pressure from teachers and parents were related to the development. 1,286 students from high-achieving high schools (46.7% female, MageT1 = 16.40) answered sociodemographic questions and questions about key variables. From T1 to T2, particularly students’ stress experience and peer satisfaction declined. Need fulfilment and perceived achievement pressure was related to changes. Implications for research and practice are discussed.

Social media use, mental health, and suicide-related outcomes in Russian women: A cross-sectional comparison between two age groups

BACKGROUND

Women who belong to the age group "emerging adulthood" (18 to 29 years) are vulnerable to mental health issues and suicide-related outcomes.

OBJECTIVES

This study investigated potential predictors of suicide-related outcomes in females emerging adulthood and compared them to older women.

DESIGN AND METHODS

Data of 2537 women from Russia (group "18 to 29 years": n = 1123; group "> 29 years": n = 1414) on lifetime suicide-related outcomes, (problematic) social media use, daily stress, depression and anxiety symptoms, and positive mental health were assessed via online cross-sectional surveys.

RESULTS

The younger group spent significantly more time on social media use than the older group. It had significantly higher levels of daily stress, problematic social media use, depression and anxiety symptoms, and suicide-related outcomes. The older group showed significantly higher levels of positive mental health. Only in the younger group, problematic social media use significantly mediated the relationship between daily stress and suicide-related outcomes in a moderated mediation analysis. Positive mental health significantly moderated the association between problematic social media use and suicide-related outcomes. Specifically, the higher the positive mental health level, the less close the link between both variables.

CONCLUSION

The current results reveal that young women in Russia could be at enhanced risk for daily stress, problematic social media use, and low levels of mental health. The interaction between these variables could foster suicide-related outcomes. Public governmental communication in Russia should call attention to potential negative impact of intensive social media use.

Mapping the Scientific Research on Suicide and Physical Activity: A Bibliometric Analysis

This research provides an overview of the current state of scientific literature related to suicide and physical activity (PA). A bibliometric analysis of studies published between 1996 and 2022 in The Web of Science (WoS) was carried out, applying the traditional bibliometric laws, using Microsoft Excel and the VOSviewer software for data and metadata processing. A total of 368 documents (349 primary research and 19 reviews) were extracted from 70 WoS categories. The results revealed an exponential increase in scientific production from 2017 to 2022 (R² = 88%), revealing the United States hegemony being the most productive country, with 156 of the publications (42.4%), the most cited (4181 citations) being the centre of a collaborative network with links to 35 countries and having April Smith, from the Miami University, as the most prolific author (eight publications) and Thomas Joiner, from the Florida State University, as the most cited author (513 citations). The Psychiatry WoS category, with 155 papers, had the highest number of publications, and The Journal of Affective Disorders, from Elsevier, had the highest number of published papers within this category.

Addictive social media use during Covid-19 outbreak: Validation of the Bergen Social Media Addiction Scale (BSMAS) and investigation of protective factors in nine countries

Since the Covid-19 outbreak, addictive social media use increased in many countries. To better understand this development, a universal instrument for the assessment of addictive social media use is required. Against this background, we examined the psychometric properties of the Bergen Social Media Addiction Scale (BSMAS) in representative population samples in nine countries (N = 9418, age range: "18 to 24 years" (youngest group), "55 years and older" (oldest group): China, France, Germany, Poland, Russia, Spain, Sweden, U.K., U.S.). Furthermore, we investigated potential factors and mechanisms that could be associated with addictive social media use. Our cross-national findings show that the BSMAS is a unidimensional reliable and valid instrument. Moreover, they reveal that the negative association between positive mental health and addictive social media use is mediated by sense of control in seven of the nine countries (exception: China, Russia). Thus, it can be hypothesized that activities which increase positive mental health could indirectly contribute to the decrease of addictive social media use. We identified conscious engagement in physical activity and a regular sleep rhythm during the pandemic as such potential activities. The fostering of both by governmental programs could enhance positive mental health and reduce addictive social media use.

The Benefits of Physical Activity and Positive Mental Health for Reducing the Burden of COVID-19: Validation from a Cross-sectional and Longitudinal Investigation in China and Germany

Many people experience high burden by the outbreak of the coronavirus disease (COVID-19) and its consequences for health and everyday life. The present cross-national study investigated potential factors that can reduce the burden by COVID-19 in China and Germany. Cross-sectional and longitudinal (China: N = 474, baseline, BL: 2015, follow-up, FU: 2020; Germany: N = 359, BL: 2019, FU: 2020) data on physical activity (e.g., jogging) (BL/FU), positive mental health (PMH) (BL/FU), and burden by COVID-19 (FU) were collected via online surveys. In both countries, physical activity was positively associated with PMH, and both variables were negatively related to burden by COVID-19. Furthermore, PMH mediated the link between physical activity and burden. The mediation model was significant when physical activity and PMH were assessed at the BL, while burden was measured at the FU; and it was also significant when all variables were assessed at the FU. The present findings reveal that physical activity in combination with PMH can reduce the experience of burden by COVID-19. Conscious fostering of physical activity and PMH is supported as an effective strategy to reduce the negative impact of the pandemic outbreak on mental and physical health. Additional benefits such as increased adherence to governmental measures around COVID-19 are discussed.

Repetitive negative thinking mediates the relationship between addictive Facebook use and suicide-related outcomes: A longitudinal study

Repetitive negative thinking (RNT) and addictive Facebook use have been shown to be associated with suicide ideation and suicidal behavior. The present longitudinal study aimed to investigate whether the association between addictive Facebook use and suicide-related outcomes is mediated by RNT. Data of 191 German Facebook users (M _age  = 26.17, SD _age  = 6.63) were assessed at two measurement time points over a one-year period (first measurement = T1, second measurement = T2) via online surveys. The significant positive association between addictive Facebook use (T1) and suicide-related outcomes (T2) was significantly mediated by RNT (T1). In contrast, a check test that included RNT (T1) as predictor and addictive Facebook use (T1) as mediator revealed no significant mediation effect. The current results demonstrate that if addictive Facebook use leads to RNT suicide ideation and attempts become likely. Therefore, RNT and addictive Facebook use should be taken into account when assessing individuals for risk of suicide.

A Bird's-Eye View of Exercise Intervention in Treating Depression Among Teenagers in the Last 20 Years: A Bibliometric Study and Visualization Analysis

Background: Exercise is medicine. Multiple studies on the effects and mechanisms of exercise in treating depression among teenagers and adolescents have been widely reported. However, literature involving scientometric analysis of this topic is sparse. Here, we endeavored to conduct a bibliometric study and visualization analysis to give a bird's-eye view of publications between 2000 and 2020 on exercise therapy treating depression. Methods: Relevant original publications were obtained from the Science Citation Index Expanded in the Web of Science Core Collection (WoSCC) database between 2000 and 2020. CiteSpace (5.7.R 5) and VOSviewer (1.6.16) software were used to perform bibliometric analysis of countries, institutions, categories, journals, authors, references, and keywords involved in this topic. Results: A total number of 975 articles on this field were retrieved from the WoSCC database and we identified an overall increase in the amount of publications over the past two decades, with the United States and Harvard University leading the field. Most related publications were published in the journals with a focus on sport, medicine, rehabilitation, psychology, and health, as represented by the dual-map overlay. A series of authors and co-cited authors were identified as main contributors in the exercise-depression-teenager domain. Three major clusters were explored based on the reference co-citation analysis: "exercise," "suicide," and "concussion". Conclusions: Current concerns and hotspots of exercise intervention in depression treatments were summarized by "individual level," "social level," "role of exercise," and "research quality." We considered that the following four directions were potential future perspectives: "research on the effect of specific exercise intervention," "research on the essence of exercise and sports," "research on the combination mode of 'exercise + X'," and "research on the micro and molecular level," which should receive more attention.
