Historical and regional particularities in the prevalence of traumatic events and posttraumatic stress disorder in East and West Germany.

BACKGROUND: Epidemiological research on the prevalence of traumatic events and PTSD has shown that there are significant differences between countries, due to their different history and socialization processes. In the case of Germany, this is particularly relevant. Germany was divided into two states from 1949 to 1990. This study examines the prevalence of traumatic events and PTSD in the formerly divided East and West Germany. METHODS: For the prevalence of traumatic events, we used data from four representative surveys (years 2005, 2007, 2008, and 2016) with a total of N = 9,200 respondents. For the analyses of PTSD prevalence, we used data from three representative surveys (years 2005, 2007, 2008) with a total of N = 6676 respondents. We compared different birth cohorts, persons living in the former West vs. East Germany, and the application of different diagnostic criteria using a chi-square test. RESULTS: The overall one-month prevalence rate for PTSD was 3.4% (3.0% for men and 3.8% for women). We found significant differences in the occurrence of traumatic events between genders, different age cohorts as well as between people who live in East and West Germany. Significant differences in the prevalence of PTSD can only be observed for different age cohorts. Most of the age effects are due to traumatic events related to World War II (WWII). Prevalence rates for PTSD were higher when the diagnostic criterions of the DSM-V were applied compared to the criterions of the DSM-IV. CONCLUSIONS: Our data suggests that socio-political factors may need to be considered when accounting for differences in occurrence rates of traumatic events, but not for prevalence rates of PTSD, between East and West Germany. People who have experienced WW II have a higher risk of suffering from PTSD. Future epidemiological trauma research should take historical and regional peculiarities of countries into account.

Adverse childhood experiences growing up in East or West Germany or abroad.

Background: Adverse childhood experiences (ACEs) are potentially traumatic events that occur before the age of 18. The term encompasses various adverse childhood experiences, e.g., physical, psychological, and sexual abuse, physical and psychological neglect, and family dysfunction. Prevalence estimates for a broad spectrum of ACEs against the background of where childhood and adolescence were spent are scarcely available in Germany. This study examines the frequencies of adverse childhood experiences, considering growing up in East or West Germany or abroad and interacting with different age cohorts and gender. Methods: A total of 5,018 individuals (51.4% female) aged 14 years and older were retrospectively assessed on adverse childhood experiences using questionnaires "adverse childhood experiences" (ACE). Logistic regression models were used to analyze the association between birth cohort, gender, and where a person grew up. Descriptive statistics and univariate analyses were used to calculate frequencies, proportions, and unadjusted associations for each variable. Results: 37.4% (N = 1,878) of respondents reported experiencing at least one form of ACE. Individuals who grew up abroad report significantly more adverse childhood experiences than individuals in East or West Germany. Men and women who grew up in East Germany reported a lower rate of ACEs. We found significant effects for all predictors: Where childhood and adolescence were predominantly spent, year of birth, and gender. Significant differences in the prevalence of adverse childhood experiences within the gender groups were only found for sexual and physical abuse and substance dependence in the household. Conclusion: The results suggest that the socio-political context plays an essential role in the experience of adverse childhood experiences, both in frequency and risk. Thus, child abuse and neglect studies should increasingly focus on societal risk and protection mechanisms.

Childhood maltreatment, depression and their link to adult economic burdens.

Background: Adult depression is a common consequence of adverse childhood experiences. There is also a higher likelihood of being affected by economic burdens after having experienced a traumatic event in childhood. As depression has been associated with economic burden, these long-term sequelae of childhood adversity are likely to interact. Goals: We investigated depression and economic consequences, such as unemployment, lower level of education, lower income as long-term sequelae of adverse childhood experiences in adulthood and their interaction. Methods: Childhood Maltreatment was measured by the German version of the Adverse Childhood Experience (ACE) questionnaire. Depression was measured by the Patient Health Questionnaire (PHQ-2). Logistic regressions were applied to investigate the risks of suffering economic burdens, with depression as a moderator. Results: Depressive symptoms increased with the number of ACEs and were highest in those reporting four or more ACEs, especially amongst those who experienced sexual and emotional abuse, as well as neglect. Moderation analysis showed a significant effect of depression increasing almost all economic burdens. Migration background additionally increased the risk of unemployment and working in a blue-collar job. Female gender decreased the risk of unemployment and working in a blue-collar job, but increased the risk of low income and part-time employment. Conclusion: The moderation effect of depression increased the negative impact of exposure to multiple ACEs on economic life in adulthood. Prevention of ACEs and early intervention are needed to prevent the mental health and economic consequences.

Ecosystems of Co-Creation.

Citizen science is becoming increasingly important as a new and participative mode of knowledge production. An essential element of citizen science is co-creation. Co-creation is by no means limited to a modus operandi for participatory science, but introduces a form of collaborative way of working with society in the sense of citizen science. Results from the H2020 SISCODE project show that co-creation is located inside and between different sectors of society. This article focuses on the question of how co-creation can be better understood in different contexts, and presents a heuristic model that has already been used for case study analyses in the SISCODE project. After an introduction to the field of co-creation and a brief description of the heuristic model, its capability is exemplarily demonstrated via application to two selected cases, followed by a discussion of central learnings and implications for further research on co-creation.
