Mental health and well-being in the first year of the COVID-19 pandemic among different population subgroups: evidence from representative longitudinal data in Germany.

OBJECTIVES: To examine potential deteriorations in mental health and well-being in the first COVID-19 pandemic year compared with the previous decade focusing on the following vulnerable subgroups in Germany: women with minor children in the household, those living without a partner, younger and older adults, those in a precarious labour market situation, immigrants and refugees, and those with pre-existing physical or mental health risks. DESIGN: Analyses of secondary longitudinal survey data using cluster-robust pooled ordinary least squares models. PARTICIPANTS: More than 20 000 individuals (aged 16+ years) in Germany. PRIMARY AND SECONDARY OUTCOME MEASURES: Mental Component Summary Scale (MCS) of the 12-item Short-Form Health Survey measuring mental health-related quality of life, single item on life satisfaction (LS). RESULTS: We find a decline in the average MCS in the 2020 survey that is not particularly striking in the overall time course, still resulting in a mean score below those of all preceding waves since 2010. We find no change in LS from 2019 to 2020 against the background of a general upward trend. Regarding vulnerability factors, only the results on age and parenthood are partially in line with our expectations. In 2020, LS declined among the youngest adults; MCS declined among mothers (and women and men without children) but not fathers. Unlike respective comparison groups, refugees, those unemployed before the pandemic and those with pre-existing mental health risks experienced no MCS declines in 2020, whereas persons living without a partner, the eldest, and those with pre-existing health risks exhibited continued increases in LS. CONCLUSIONS: There is no evidence for substantial breakdowns in mental health or subjective well-being in the first pandemic year in the German population or its subgroups, particularly when considering developments of the previous decade. Since the majority of hypothesised vulnerable groups to pandemic stressors showed more stable MCS and LS, our results warrant further study.

Religious responses to existential insecurity: Conflict intensity in the region of birth increases praying among refugees.

Do violent conflicts increase religiosity? This study draws on evidence from a large-scale survey among refugees from Afghanistan, Iraq, and Syria in Germany linked with data on time-varying conflict intensity in refugees' birth regions before the survey interview. The results show that the greater the number of conflict-induced fatalities in the period before the interview, the more often refugees pray. The relationship between conflict and praying holds equally across demographic subgroups. Evidence suggests that both short- and long-term cumulative fatalities in refugees' birth regions affect how often they pray. Additionally, the link between conflict and praying is stronger for refugees with family and relatives still living in their country of origin. Finally, we show that the conflicts that matter are those occurring within the refugees' specific region of birth rather than in other regions in the country. Implications for existential insecurity theory and cultural evolutionary theory are discussed.

Resilient or Vulnerable? Effects of the COVID-19 Crisis on the Mental Health of Refugees in Germany.

Even though the COVID-19 pandemic had consequences for the whole society, like during most crises, some population groups tended to be disproportionally affected. We rely on the most recent data from the IAB-BAMF-SOEP Survey of Refugees to explore the resilience or vulnerability of refugees in the face of the pandemic. As the 2020 wave of the survey was in the field when the second nationwide lockdown started in December, we are able to apply a regression discontinuity design to analyze how refugees in Germany are coping with these measures. Our results reveal a negative effect of the lockdown on refugees' life satisfaction. Male refugees and those with a weaker support system face stronger negative outcomes than their counterparts. Since mental health is an important prerequisite for all forms of integration, understanding the related psychological needs in times of crisis can be highly important for policymakers and other stakeholders.

The reliability of adult self-reported height: The role of interviewers.

Surveys serve as an important source of information on key anthropometric characteristics such as body height or weight in the population. Such data are often obtained by directly asking respondents to report those values. Numerous studies have examined measurement errors in this context by comparing reported to measured values. However, little is known on the role of interviewers on the prevalence of irregularities in anthropometric survey data. In this study, we explore such interviewer effects in two ways. First, we use data from the US National Health and Nutrition Examination Survey and the UK Household Longitudinal Study to evaluate whether differences between reported and measured values are clustered within interviewers. Second, we investigate changes in adult self-reported height over survey waves in two German large-scale panel surveys. Here, we exploit that height should be constant over time for the majority of adult age groups. In both analyses, we use multilevel location-scale models to identify interviewers who enhance reporting errors and interviewers for whom unlikely height changes over waves occur frequently. Our results reveal that interviewers can play a prominent role in differences between reported and measured height values and changes in reported height over survey waves. We further provide an analysis of the consequences of height misreporting on substantive regression coefficients where we especially focus on the role of interviewers who reinforce reporting errors and unlikely height changes.

How to Catch a Falsifier: Comparison of Statistical Detection Methods for Interviewer Falsification.

Deviant interviewer behavior is a potential hazard of interviewer-administered surveys, with interviewers fabricating entire interviews as the most severe form. Various statistical methods (e.g., cluster analysis) have been proposed to detect falsifiers. These methods often rely on falsification indicators aiming to measure differences between real and falsified data. However, due to a lack of real-world data, empirical evaluations and comparisons of different statistical methods and falsification indicators are scarce. Using a large-scale nationally representative refugee survey in Germany with known fraudulent interviews, this study tests, evaluates, and compares statistical methods for identifying falsified data. We investigate the use of new and existing falsification indicators as well as multivariate detection methods for combining them. Additionally, we introduce a new and easy-to-use multivariate detection method that overcomes practical limitations of previous methods. We find that the vast majority of used falsification indicators successfully measure differences between falsifiers and nonfalsifiers, with the newly proposed falsification indicators outperforming some existing indicators. Furthermore, different multivariate detection methods perform similarly well in detecting the falsifiers.

The Impact of Pre- and Postarrival Mechanisms on Self-rated Health and Life Satisfaction Among Refugees in Germany.

In this study, we focus on the evolution of refugees' well-being in the first years after their arrival in Germany. In contrast to other immigrants (e.g., labor migrants), refugees experience higher risks of unexpected and traumatic events and insecurity before and during their migration and face various legal and structural barriers in the receiving country. We contribute to the existing literature by exploring from a dynamic perspective possible pre- and postarrival determinants of refugees' life satisfaction and self-rated health upon arrival in Germany and the development of their life satisfaction and self-rated health in the process of becoming established. Applying linear regression and panel models with recent longitudinal data from the IAB-BAMF-SOEP Survey of Refugees in Germany, we find significant effects of prearrival factors, such as traumatic experiences and the complexity of migration, on both life satisfaction and self-rated health at the time of the first interview. Regarding postarrival factors, our results suggest that improvement in language proficiency and labor market status significantly shape refugees' life satisfaction and self-rated health. The time-dynamic analyses reveal substantial improvements in life satisfaction upon the approval of refugee status and the transition from shared housing to private accommodations. However, we find no improvements in self-rated health due to legal status but rather deterioration effects due to long-term residence in shared housing.
