Assessment of subjective emotional valence and long-lasting impact of life events: development and psychometrics of the Stralsund Life Event List (SEL)

How socio-political change is associated with the number of individually reported negative life events: a population-based study using the German reunification 1989/1990 as an example

BACKGROUND

Socio-political change often leads to disruptions in employment and social networks, which can exacerbate health issues and increase mortality rates. These consequences are likely observed as an increase in negative life events (NLEs), serving as indicators of the broader social and health impacts. Using the German reunification in 1989/1990 as an example, this study investigates changes in reported numbers of NLEs and differences regarding sociodemographic characteristics.

METHODS

We used data from the population-based Study of Health in Pomerania (SHIP-START-0, SHIP-Life-Events and Gene-Environment Interaction in Depression; N=1932). Numbers of NLEs in different categories (work/financial, social/interpersonal, illness (own) and illness/death (others)) were measured retrospectively in 5-year intervals (1980-2004) using a semistructured interview. Pre-reunification and post-reunification changes were modelled using piecewise mixed-effects Poisson regressions with the 1990-1994 interval (reunification) as change point. Interactions with age, sex and education were examined.

RESULTS

The number of most NLE categories, except social/interpersonal NLEs, increased at reunification. Whereas work/financial NLEs slightly decreased post-reunification, illness-related NLEs continued to increase. Higher numbers of social/interpersonal NLEs were found with younger age. More illness-related NLEs were reported with older age, lower education (illness (own)) and by women (illness/death (others)). However, the majority reported no NLEs at reunification (68.2%-80.7%, varying by category).

CONCLUSION

Our findings suggest that although some individuals experience a marked increase in NLEs due to socio-political changes, many remain unaffected, emphasising the need for a differentiated understanding of these effects. This increase in NLEs may partly account for ongoing health and well-being disparities among countries with differing transformation histories.

[Life events related to the German reunification and their associations with psychosocial health in a sample of northeast Germany]

Objectives: The aim of the present study was to investigate (1) the type and frequency of reported life events of the East German population related to the German reunification and (2) their associations with psychosocial health. Methods: Data of 2247 participants of the Study of Health in Pomerania was used.These qualitative responses were analysed using quantitative content analysis. Their associations with subjective physical and mental health, optimism, social support, depressive symptoms, and chronic stress were examined. Results: Eight life event categories were identified (education, employment-related changes, material changes, new opportunities, personal life events, politics, separations, reunifications). Especially, experiencing new opportunities was associated with a higher level of optimism as well as a lower level of depressive symptoms and chronic stress. Conclusions: In this study, events frequently described in the literature (e.g., employment-related and social changes) were confirmed and systematized.The observed associations of these events with psychosocial factors should be examined further in future studies.

Subjective perception of life stress events affects long-term pain: the role of resilience

OBJECTIVE

There is evidence that experiencing childhood trauma and life stressors across the lifespan together with lower resilience is associated with chronic pain-related conditions. The aim of this study was to explore the potential mediating role of resilience in the relationship between childhood trauma and long-term pain and to explore a possible moderating role of serious life stressors in the last year.

METHODS

The participants, drawn from a representative sample of citizens of the Czech Republic (n = 1800, mean age: 46.6 years, 48.7% male), were asked to report various long-term pain conditions, childhood trauma (Childhood Trauma Questionnaire, CTQ), life stressors (Life Stressor Checklist Revised, LSC-R) and resilience (Brief Resilience Scale, BRS) in a cross-sectional face-to-face study conducted in 2016. A conditional process SEM model of moderated mediation was performed.

RESULTS

The occurrence of life stress events affecting the participant's last year moderated the relationship between childhood trauma, resilience and health. In the group of participants who experienced at least one life stress event affecting their last year, resilience fully mediated the effect of past childhood trauma on long-term pain. In participants who did not experience life stressors with an impact on the last year, the direct path from childhood trauma to health through resilience lost its significance.

CONCLUSION

The subjective meaning of stress events on one's life has an impact on the trajectory between childhood trauma and health and acts as a moderator. Resilience may buffer the negative effect of trauma on later long-term pain.

The Broken Heart: The Role of Life Events in Takotsubo Syndrome

The onset of Takotsubo syndrome (TTS), also known as stress cardiomyopathy, is thought to be associated with some life events. This study focuses on clarifying life event characteristics and the role of triggers in the onset of TTS. Participants with TTS (n = 54) were compared to those with acute myocardial infarction (AMI; n = 52) and healthy individuals (n = 54). Using a modified version of the Interview for Recent Life Events, information about general life events perceived as stressful and triggers preceding the onset of a cardiac syndrome was collected. The assessment included the impact of these events as indicated by the participants and estimated by the interviewer; finally, the objective impact was considered. Although the number of events and the objective impact did not differ among the groups, patients with TTS reported a more negative perceived impact. Moreover, 61% of these patients objectively and subjectively reported a more stressful trigger before the onset of the disease (in the 24 h preceding the cardiac event) than those reported by patients with AMI. The dynamic between life events and individual responses could help differentiate TTS from other cardiovascular events, such as AMI. This study suggests that patients' perception of some life events (whether triggers or general life events) could represent a possible marker of TTS.

Similarities and Differences of Mental Health in Women and Men: A Systematic Review of Findings in Three Large German Cohorts

In Germany, large, population-based cohort studies have been implemented in order to identify risk and protective factors for maintaining health across the life span. The purpose of this systematic review is to analyse findings from three large ongoing cohorts and to identify sex-specific prevalence rates, risk and protective factors for mental health. Published studies from the Cooperative Health Research in the Region Augsburg (KORA), the Study of Health in Pomerania (SHIP) and the Gutenberg Health Study (GHS)), representing the southern, north-eastern and middle parts of Germany, were identified through searches of the databases PubMed and Web of Science. A total of 52 articles was identified from the start of each cohort until June 2019. Articles reporting prevalence rates of mental health [N = 22], explanatory factors for mental health [N = 25], or both [N = 5] were identified. Consistent across cohorts, higher prevalence rates of internalizing disorders were found for women and more externalizing disorders for men. Risk and protective factors for mental health included social factors, lifestyle, physical health, body mass index (BMI), diabetes, genetic and biological factors. In all areas, differences and similarities were found between women and men. The most evident were the sex-specific risk profiles for depression with mostly external risk factors for men and internal risk factors for women. Gender was not assessed directly, therefore we examined whether socioeconomic and family-related factors reflecting gender roles or institutionalized gender could be used as a proxy for gender. Overall, this systematic review shows differences and similarities in prevalence rates and determinants of mental health indicators between women and men. They underline the importance of focussing on sex specific approaches in mental health research and in the development of prevention measures. Current research on mental health still lacks focus on gender aspects. Therefore, an increased focus on sex and gender in mental health research is of great importance.

Negative and positive life events and their relation to substance and behavioral addictions

BACKGROUND

Research has shown that negative life events (LEs) may be connected to the development and maintenance of addictions. However, few studies have examined the potential relationship between positive events and addictive disorders, and even fewer studies evaluated the subjective perception of LEs that may underlie these relationships. Importantly, addictive disorders include both substance-related and behavioral addictions, but the relative relationship of each type of addiction with LEs remains unclear.

METHODS

The present study compared 212 participants suffering from an addiction (drugs, alcohol, gambling, and sex) and 79 controls on self-report measures of negative and positive LEs.

RESULTS

Compared with controls, individuals with an addiction reported experiencing a larger number of both negative and positive LEs and also tended to be more influenced by negative LEs. Findings also demonstrated differential patterns across addiction types, such that participants with compulsive sexual behavior (CSB) reported experiencing less negative events than those with drug use disorders (DUD) and were less influenced by these events than participants with alcohol use disorder (AUD). Finally, analyses within each group further revealed differences in the way each group experienced negative compared to positive events. Controls and participants with CSB reported experiencing a similar number of positive and negative events, whereas participants with DUD, AUD, and gambling disorder reported more negative events in their lives.

CONCLUSIONS

These findings suggest a unique profile among different types of addictions, which should be taken into account when planning personalized prevention and intervention approaches.

Methylation of the FKBP5 gene in association with FKBP5 genotypes, childhood maltreatment and depression

DNA methylation of the FKBP5 gene is assumed to alter FKBP5 expression and hence the synthesis of the FK506 binding protein 51, a central element of a genomic negative feedback loop for glucocorticoid receptor signaling. The present study aimed to replicate and extend previously reported influences of FKBP5 genotypes, childhood maltreatment and depression on methylation levels of five CpG sites in intron 7 of the FKBP5 gene in a large population-based sample. Besides the single nucleotide polymorphism (SNP) rs1360780, associations of the FKBP5 methylation with 22 other, unlinked FKBP5 SNPs as well as associations between FKBP5 methylation levels and transcription levels were investigated. Using whole-blood methylation of 3965 subjects of the Study of Health in Pomerania (SHIP) reduced methylation levels in TT allele carriers of rs1360780 (OR = 0.975, p = .005) and currently depressed subjects (OR = 0.995, p = 0.005) were found. Further, an impact of two yet undescribed SNPs (rs6910300, rs7771727) on methylation levels was observed. However, main and interactive effects for childhood maltreatment and lifetime major depressive disorder observed in previous studies could not be replicated. Finally, FKBP5 methylation levels were not related to FKBP5 transcription levels in whole blood. Thus, the present study verified the associations of FKBP5 genotypes and state depression on the FKBP5 methylation levels of five CpG sites in intron 7. However, FKBP5 methylation of these five CpG sites could not be validated as a valuable clinical biomarker for biological long-term effects of childhood maltreatment or lifetime depression.
