Short-term exposure to ultrafine and fine particulate matter with multipollutant modelling on heart rate variability among seniors and children from the CorPuScula (coronary, pulmonary, sanguis) longitudinal study in Germany.

Short-term exposure particulate matter with a diameter of 10 µm or less (PM10) and fine particulate matter (PM2.5) has been associated with heart rate variability (HRV), but exposure to ultrafine particles (UFP) has been less well examined. We investigated the associations between the HRV outcomes and short-term exposure to UFP, PM10 and PM2.5 among school-aged children and seniors. CorPuScula (Coronary, Pulmonary and Sanguis) is a longitudinal, repeated-measure panel study conducted in 2000-2002 in Munich, Germany including 52 seniors (58-94 years old) with 899 observations and 50 children (6-10 years old) with 925 observations. A 10-min resting electrocardiogram was performed to assess resting HRV outcomes [Standard Deviation of Normal to Normal Intervals (SDNN), Root Mean Square of Successive Differences between Normal Heartbeats (RMSSD), Low Frequency power (LF), High Frequency power (HF), ration between low and high frequency (LF/HF)]. UFP and PM exposures were measured near the care home and school yard for seniors and children, respectively. Mean exposures during the day of examination (9-21 h) as well as 3-h, 12-h, 24-h, one-day, and two-day lags were assessed. Linear mixed-effect models were used to investigate the associations between short-term air pollution and HRV outcomes separately in children and seniors. The models were adjusted for sex, age, weather conditions (temperature, precipitation, and water vapor pressure), BMI, lifestyle and medical information. Two and multipollutant models adjusted for NO2 and O3 were performed. Among seniors, we observed increases in SDNN, LF, HF and LF/HF ratio after short-term exposure to UFP (hourly and daily lags) in contrast to decreases in SDNN and RMSSD after exposure to PM10. Associations were generally robust to two- and multipollutant adjustment. Among children, we observed increases of the LF/HF ratio after short-term exposures to UFP at lags 12 and 24 h. In contrast, we observed decreases of the ratio after exposure to PM2.5 and PM10. Results were largely unchanged for multipollutant modelling, however we found a more pronounced increase in SDNN and LF/HF (UFP lag 12 and 24 h) after adjusting for NO2. Overall, among seniors, we observed associations of UFP and PM10 exposure with sympathetic responses of the ANS, which play an important role in sudden heart attacks or arrhythmia. Among children we found more inconsistent associations between UFP and a delayed increase in HRV. Adjusting for co-pollutants including NO2 and O3 yielded robust results.

Mental health across two years of the COVID-19 pandemic: a 5-wave longitudinal study in Germany.

The COVID-19 pandemic has been negatively associated with mental health. However, little is known about the temporal dynamics of mental health in the longer term of the pandemic. We aimed to investigate symptom levels and changes of depression, anxiety, posttraumatic stress, and loneliness spanning two years of the pandemic; and to examine associated risk factors. This five-wave, longitudinal online study from May 2020 to April 2022 included 636 adults (Mage = 39.5 years, SD = 16.11; 84.1% female) from the German general population who completed the international COVID-19 Mental Health Survey. Symptoms of anxiety (Generalized Anxiety Disorder-7; GAD-7), depression (Patient Health Questionnaire-9; PHQ-9), posttraumatic stress (PTSD Checklist for DSM-5; PCL-5), and loneliness ("Do you feel lonely?") were assessed using mixed-effects models. Associations with anxiety and depressive symptoms were examined with having children, student status, financial worries, contamination fear, and loneliness. PHQ-9, GAD-7, PCL-5, and loneliness scores overall decreased throughout the two-year period of the pandemic but exhibited an increase during two national lockdowns. Controlled for significant associations with female gender and younger age, increased PHQ-9 and GAD-7 scores were associated with contamination fear, financial worries, and loneliness. No associations were found with having children and student status. Symptoms of depression, anxiety, posttraumatic stress, and loneliness decreased over time but varied along with the dynamics of the pandemic. Longitudinal monitoring of mental health in vulnerable subgroups is required, especially those of younger age, females, and the financially insecure.

A tool to assess fitness among adults in public health studies – Predictive validity of the FFB-Mot questionnaire

BackgroundFitness has important implications for physical activity behavior and is associated with various health-related outcomes. It can be assessed through a test battery or a self-reported questionnaire. One example is the FFB-Mot (Funktionsfragebogen Motorik; engl. functional fitness questionnaire) which consist of 28 items to assess four components of fitness in adults: cardiorespiratory fitness/ endurance, muscular strength, gross motor coordination, and flexibility. The aims of this manuscript were to (1) provide an English-version of the FFB-Mot questionnaire (developed from the German-version using translation and back-translation) to the international community of researchers in the areas of physical activity, fitness and health in adults, and (2) examine the predictive validity of the FFB-Mot questionnaire in a large sample of community-dwelling adults.MethodsWe used data from a longitudinal study in Germany with four measurement waves over a period of 18 years, with samples ranging between 310 and 437 participants (1572 adults in total, mean ages 46–58 years). To assess predictive validity, we calculated Pearson correlations between FFB-Mot data collected in 1997 and external health-related criteria (i.e., subjective health status, physician-rated health status, back pain, physical complaints and physical activity in minutes per week) collected in 2002, 2010, and 2015, and separately for males and females.ResultsWe observed correlations between higher FFB-Mot scores with better subjective health status (in 2002: males, r = 0.25; females, r = 0.18; in 2010: males, r = 0.29; females, r = 0.28; in 2015: males, r = 0.40), and higher physical activity (in 2002: males, r = 0.24; females, r = 0.25; in 2010: males, r = 0.30; females, r = 0.38; in 2015: females, r = 0.27). Higher FFB-Mot scores were also correlated with lower back pain (in 2002: males, r = -0.23; females, r = -0.25; in 2010: females, r = -0.22), less physical complaints (in 2002: males, r = -0.36; females, r = -0.24), and better physician-rated health status (in 2002: males, r = -0.41; females, r = -0.29, 2010: males, r = -0.38; females, r = -0.44; in 2015: males, r = -0.47).ConclusionsOur results suggest that the FFB-Mot to assess fitness in adults has predictive validity for health-related outcomes as indicated by significant correlations, albeit some effect sizes are small. The FFB-Mot may be used as one-time assessment of self-reported fitness, or for repeated testing to assess change of self-reported fitness over time and in different settings (e.g., public health research).

Pre-Service Primary School Teachers Interdisciplinary Competence and their Interest, Self-Concept, and Sense of Belonging Regarding Natural and Social Sciences: Findings from a Longitudinal Study in Germany

In German primary schools, natural sciences and social studies are learned and taught in an integrative manner within a subject called Sachunterricht. To teach Sachunterricht in a high-quality manner, it is reasonable to assume that primary school teachers themselves require—among other things, such as knowledge about pedagogy, teaching Sachunterricht, and the various content areas of Sachunterricht—a distinct interest, academic self-concept, and sense of belonging regarding natural and social sciences. Furthermore, they should possess a solid interdisciplinary competence that enables them to teach natural and social sciences in an integrative way. In the present study, we conducted a longitudinal survey of pre-service primary school teachers from a German university over a period of 2 years to investigate the changes in their (self-evaluated) interdisciplinary competence; the changes in their interest, academic self-concept, and sense of belonging regarding natural and social sciences; and the correlations between these constructs. Our data analysis revealed a decrease over time in participants’ sense of belonging to natural and social sciences, as well as their (self-evaluated) interdisciplinary competence, while their academic self-concept in natural and social sciences remained stable. Participants’ interest in social sciences decreased, while their interest in natural sciences increased. Moreover, we found varying degrees of correlation between these constructs. In summary, the results of the present study provide important insights into the professional development of pre-service primary school teachers within university-based teacher education for teaching natural and social sciences in primary school. The implications of these findings are discussed in detail at the end of this paper.

The Influence of Ethical Responsiveness on Relationships Through Distress

This study examined the role of ethical responsiveness on relationship satisfaction from a partner's perspective after experiencing a distressing life event (DLE). We used data from the Panel Analysis of Intimate Relationships and Family Dynamics (pairfam), which is a multidisciplinary, longitudinal study in Germany. Our study used anchor data, the original respondents who were randomly selected and gave permission to interview their partners. This study included two waves of anchor responses, which were 2016 and 2018, respectively. We utilized longitudinal structural equation modeling to evaluate whether the partner's ethical responsiveness buffers the negative impact of DLEs on relationship satisfaction per anchor's perspective. The results of our study indicated that partner's ethical responsiveness can buffer the negative impact of DLEs on anchor's perception of relationship satisfaction. Additionally, according to the perception of the anchors, we found that the partners who showed high levels of ethical responsiveness not only maintained their relationship satisfaction but even improved upon it 2 years beyond the DLE. Conversely, relationship satisfaction decreased over time for anchors who reported their partner with an average or lower level of ethical responsiveness. Clinical implications and limitations are also discussed.

Alcohol use during COVID-19 pandemic on the long run: findings from a longitudinal study in Germany

BackgroundThe impact of COVID-induced stress on mental health and alcohol use has been demonstrated in recent research. However, there is a lack of longitudinal data since most studies reported on cross-sectional data. It remains unclear how alcohol use develops under the dynamic changes of the pandemic. Therefore, the present study aims to investigate the general development of alcohol use and the impact of COVID related stress on drinking behavior in a German population-based sample during the pandemic in 2020.MethodsIn the longitudinal design with three measurements (baseline [T1] and two follow-ups [T2, T3]) an online survey was administered. The survey included the Alcohol Use Disorder Identification Test (AUDIT) as well as the assessment of the drinking days in the last 30 days, the number of alcoholic beverages on each occasion and changes in alcohol use in the previous fourteen days. Further, COVID-19 related concerns, perceived stress, worries about friends and family and worries about the financial situation were also assessed and multiple linear regressions and confidence intervals (CI) were calculated.Results1050 participants started the survey, 756 participants (71.4%), 317 (52.7%) participants completed the survey at all three measurements. Seventy six percent (n = 241) of the sample were female. An increase in alcohol use in the previous 14 days was reported by 10.9% at T1, 3.9% at T2 and 3.6% at T3. Moreover, a decrease in alcohol use in the previous 14 days was reported by 8.7% at T1, 6.5% at T2 and 4.1% at T3. The number of drinking days was significantly higher at T2 than at baseline (p < .001; F = − 2.06, [CI − 3.10, − 1.02]). COVID-19 related concerns and stress were associated with a higher number of drinking days and average number of drinks at a typical occasion. AUDIT score at baseline positively predicted number of drinking days as well as average number of drinks.ConclusionsThe significant increases in alcohol use is a public health issue during COVID-19 pandemic. The findings show that especially people who drink more hazardously previously tend to drink more under pandemic conditions. Those individuals are particularly at risk for developing substance-related problems.

SARS-CoV-2 viral clearance and viral load kinetics in young children (1-6 years) compared to adults: Results of a longitudinal study in Germany.

To investigate SARS-COV-2 viral clearance and viral load kinetics in the course of infection in children aged 1-6 years in comparison with adults. Prospective cohort study of infected daycare children and staff and their close contacts in households from 11/2020 to 06/2021. Adult participants took upper respiratory tract specimen from themselves and/or their children, for PCR tests on SARS-CoV-2. Data on symptoms and exposure were used to determine the date of probable infection for each participant. We determined (a) viral clearance, and (b) viral load dynamics over time. Samples were taken from day 4-6 to day 16-18 after diagnosis of the index case in the respective daycare group (5 samples per participant). We included 40 children (1-6 years) and 67 adults (18-77 years) with SARS-CoV-2 infection. Samples were available at a mean of 4.3 points of time per participant. Among the participants, the 12-day study period fell in different periods within the individual course of infection, ranging from day 5-17 to day 15-26 after assumed infection.Children reached viral clearance at a median of 20 days after assumed infection (95% CI 17-21 days, Kaplan-Meier Analysis), adults at 23 days (95% CI 20-25 days, difference not significant). In both children and adults, viral load decreased over time with trajectories of the mean viral load not being statistically different between groups. Kaplan-Meier calculations show that from day 15 (95% CI 13-15), 50% of all participants had a viral load <1 million copies/ml, i.e. were no longer infectious or negative. Children aged 1-6 and adults infected with SARS-CoV-2 (wild type and Alpha variant) did not differ significantly in terms of viral load kinetics and time needed to clear the virus. Therefore, containment measures are important also in the daycare settings as long as the pandemic continues.

Determinants of adoption and rejection of protective measures during the SARS-CoV-2 pandemic: A longitudinal study in Germany’s second wave

The adoption and acceptance of protective measures are crucial for containing the ongoing coronavirus disease (COVID-19) pandemic. In a recent article in this journal, Dohle et al. (https://doi.org/10.32872/spb.4315) investigated the influence of risk perceptions and trust in politics and science on those constructs in March/April 2020. Since then, the pandemic has undergone several dynamic changes. We analyzed longitudinal data (N = 800) to investigate whether trust and risk were relevant predictors for pandemic measures at a later stage (October 2020/January 2021). The concept of risk perception was supplemented by risk attitude and affective risk to produce a more comprehensive picture of the risk component. We found that greater trust in science at time point 1 predicted less rejection and more adoption of measures at time point 2. Moreover, trust in politics predicted less rejection of measures. From all aspects of cognitive risk perception, only higher severity predicted lower rejection. All other cognitive aspects were non-significant. However, affective risk was shown to be a major predictor: the more the coronavirus was perceived as frightening and worrisome, the lower the rejection and more frequent the adoption of measures. Also, the higher the risk attitude related to health topics, the less frequent the implementation of measures. We replicated the analysis with predictors from time point 2 and deviations are discussed. Our results indicate that affective risk and general attitude toward health risk are more predictive of taking up measures in the context of COVID-19 than cognitive risk.

Time Trend in SARS-CoV-2 Seropositivity, Surveillance Detection- and Infection Fatality Ratio until Spring 2021 in the Tirschenreuth County-Results from a Population-Based Longitudinal Study in Germany.

Herein, we provide results from a prospective population-based longitudinal follow-up (FU) SARS-CoV-2 serosurveillance study in Tirschenreuth, the county which was hit hardest in Germany in spring 2020 and early 2021. Of 4203 individuals aged 14 years or older enrolled at baseline (BL, June 2020), 3546 participated at FU1 (November 2020) and 3391 at FU2 (April 2021). Key metrics comprising standardized seroprevalence, surveillance detection ratio (SDR), infection fatality ratio (IFR) and success of the vaccination campaign were derived using the Roche N- and S-Elecsys anti-SARS-CoV-2 test together with a self-administered questionnaire. N-seropositivity at BL was 9.2% (1st wave). While we observed a low new seropositivity between BL and FU1 (0.9%), the combined 2nd and 3rd wave accounted for 6.1% new N-seropositives between FU1 and FU2 (ever seropositives at FU2: 15.4%). The SDR decreased from 5.4 (BL) to 1.1 (FU2) highlighting the success of massively increased testing in the population. The IFR based on a combination of serology and registration data resulted in 3.3% between November 2020 and April 2021 compared to 2.3% until June 2020. Although IFRs were consistently higher at FU2 compared to BL across age-groups, highest among individuals aged 70+ (18.3% versus 10.7%, respectively), observed differences were within statistical uncertainty bounds. While municipalities with senior care homes showed a higher IFR at BL (3.0% with senior care home vs. 0.7% w/o), this effect diminished at FU2 (3.4% vs. 2.9%). In April 2021 (FU2), vaccination rate in the elderly was high (>77.4%, age-group 80+).

Short-Term Effects of Short-Term Work: Dynamics in Fatigue Across Two National Lockdowns.

Anecdotal evidence suggests work fatigue has increased during the COVID-19 pandemic, and work interventions to offset stresses have been effective. Our study sought to test these propositions, documenting and describing the complexity of worker well-being around two lockdown periods. Using 17 waves of data from a longitudinal study in Germany (December 2019 to June 2021, n = 1053 employees), we model discontinuous changes in work fatigue and how participation in a government-sponsored short-term work program (Kurzarbeit) affected change trajectories. The COVID-19 pandemic has not invariably resulted in work fatigue, and individuals with Kurzarbeit at the first lockdown (but not the second) showed significantly larger decreases in each form of fatigue at this transition. Future policy interventions will require more contextual nuance and to effectively support worker well-being during public health crises.

Time-varying testosterone level and risk of myocardial infarction and stroke among hypogonadal men: a longitudinal study in Germany

Background and objective: Findings on the association between testosterone and cardiovascular risk in men have been inconsistent. Previous studies investigated this association based on testosterone level measured at one single point in time (e.g., testosterone level at the baseline visit), which might not be relevant for the future cardiovascular events that occurred many years later, given the dynamic changes of testosterone level over time. Additionally, as compared to patients without prior cardiovascular history, those with prior cardiovascular events are more likely to have pathological changes in coronary or peripheral vasculature, and therefore more susceptible to cardiovascular events when exposed to risk factors. However, whether time-varying testosterone level affects differently between patients with prior cardiovascular events and those without is unknown. The objective of this study was to investigate the association between time-varying testosterone level and risks of myocardial infarction and stroke, and compared the associations stratified by patient’s prior cardiovascular event history. Material and methods: We used data of 376 hypogonadal men from a registry study in Germany with up to 11 years’ follow-up and applied Cox proportional hazards regression models to investigate the proposed association. Results: No association was found between baseline testosterone level and risks of myocardial infarction and stroke. When taking into account the changes of testosterone level over time and including testosterone as a time-varying covariate in the model, the adjusted hazard ratio (HR) for myocardial infarction associated with 1 nmol/L increase in testosterone level was 0.78 (95% CI: 0.64, 0.97); no association between time-varying testosterone level and stroke was found. The associations between testosterone level and cardiovascular risk were not different among patients with prior cardiovascular event history and those without. Conclusion: One baseline measurement of testosterone level may be insufficient to predict one’s future risk of cardiovascular events; regular monitoring of testosterone levels may be useful to assess the short-term cardiovascular risk in men.

Association Between Sense of Coherence and Health Outcomes at 10 and 20 Years Follow-Up: A Population-Based Longitudinal Study in Germany.

Background: The sense of coherence (SOC) is reported to influence health, but health may also have an impact on SOC. The objective of this study was to examine the longitudinal associations between SOC and selected self-reported and physician-assessed health outcomes over a period of 10 and 20 years and to determine the predominant direction of the associations.Methods: We conducted a population-based, longitudinal study, involving 392 participants (188 females and 204 males; mean age 43.01 years) who were followed for a median of 10 and 18 years. Analyses of variance were carried out to examine the longitudinal associations between SOC at baseline and health outcomes (i.e., self-rated health status, SHS; physical health status assessed by a physician, PHS; self-reported satisfaction with life, SWL) at follow-ups. The direction of associations was examined using a cross-lagged model on correlation coefficients.Results: There were significant group effects for SOC at baseline on SHS at 20-year follow-up (F = 4.09, p = 0.018, ηp2 = 0.041), as well as on SWL at 10-year (F = 12.67, p < 0.01, ηp2 = 0.072) and at 20-year follow-up (F = 8.09, p < 0.1, ηp2 = 0.069). SHS (r = 0.238, p < 0.01), PHS (r = −0.140, p < 0.05) and SWL (r = 0.400, p < 0.01) predicted SOC at 10-year follow-up stronger than vice versa. The direction of associations between SOC and health parameters at 20-year follow-up was less consistent.Conclusions: The long-term associations between SOC and self-reported and physician-assessed health may be reciprocal in community-dwelling adults. More research is needed to examine the predictive power of health on SOC and whether interventions targeted at improving health parameters, may impact SOC.

Socio-economic consequences of mental distress: quantifying the impact of self-reported mental distress on the days of incapacity to work and medical costs in a two-year period: a longitudinal study in Germany

BackgroundMental disorders are related to high individual suffering and significant socio-economic burdens. However, it remains unclear to what extent self-reported mental distress is related to individuals’ days of incapacity to work and their medical costs. This study aims to investigate the impact of self-reported mental distress for specific and non-specific days of incapacity to work and specific and non-specific medical costs over a two-year span.MethodWithin a longitudinal research design, 2287 study participants’ mental distress was assessed using the Hospital Anxiety and Depression Scale (HADS). HADS scores were included as predictors in generalized linear models with a Tweedie distribution with log link function to predict participants’ days of incapacity to work and medical costs retrieved from their health insurance routine data during the following two-year period.ResultsCurrent mental distress was found to be significantly related to the number of specific days absent from work and medical costs. Compared to participants classified as no cases by the HADS (2.6 days), severe case participants showed 27.3-times as many specific days of incapacity to work in the first year (72 days) and 10.3-times as many days in the second year (44 days), and resulted in 11.4-times more medical costs in the first year (2272 EUR) and 6.2-times more in the second year (1319 EUR). The relationship of mental distress to non-specific days of incapacity to work and non-specific medical costs was also significant, but mainly driven from specific absent days and specific medical costs. Our results also indicate that the prevalence of presenteeism is considerably high: 42% of individuals continued to go to work despite severe mental distress.ConclusionsOur results show that self-reported mental distress, assessed by the HADS, is highly related to the days of incapacity to work and medical costs in the two-year period. Reducing mental distress by improving preventive structures for at-risk populations and increasing access to evidence-based treatments for individuals with mental disorders might, therefore, pay for itself and could help to reduce public costs.

Friends\u2019 influence on the development of academic values in mathematics: are there differences between female and male dyads?

Based on the social cognitive theory and the emotional contagion theory, this study investigated if friends influence (reinforce or change) the development of academic values (intrinsic value, emotional cost) and if this process differs across same-sex friendship dyads. We drew on data collected in a two-wave longitudinal study in Germany. The final sample was based on 264 stable reciprocated friendship dyads of grades 5 and 7 (148 female dyads and 116 male dyads). Results of actor-partner-interdependence models indicated that friends reinforce each other regarding the intrinsic value and initiate change regarding the emotional cost. Moreover, female and male friendship dyads did not differ in the strength of influence on academic values. Results were discussed in terms of selection and socialization effects regarding friendships.

Effects of student composition in school on young adults’ educational pathways.

Which factors help young adults choose educational pathways leading to higher educational attainment? Academic self-concept (ASC), achievement, and socioeconomic background have all been found to be important predictors of postsecondary educational choices and success. Although research has shown that student composition in secondary school may affect some of these predictors, only a few studies (mostly from the United States) have investigated the effects of student composition on postsecondary educational outcomes. The results showed that students with similar individual achievement had lower postsecondary educational attainment if they graduated from secondary schools with higher mean achievement. It has been proposed that social comparison processes explain this negative context effect (big-fish-little-pond effect [BFLPE]). In contrast, students with the same individual socioeconomic status (SES) had higher postsecondary educational attainment if they graduated from secondary schools with a higher mean SES. In the present study, we investigated the effects of achievement-related and socioeconomic student composition on subsequent educational outcomes using data from a longitudinal study in Germany. Contrary to previous studies, our results showed that student composition had little relevance for later educational pathways. There was a small, long-lasting, indirect BFLPE of achievement-related composition in secondary school on postsecondary educational outcomes through students’ ASC. Furthermore, individual SES was strongly related to postsecondary educational outcomes, whereas being in an academic-track school with a higher or lower mean SES was not relevant for postsecondary educational pathways.

The transmission of academic values between best friends: How important is an accurate perception?

IntroductionBased on the expectancy-value theory and value transmission theory, the present study investigated the transmission process of academic values between best friends within the classroom. Expectancy-value theory argues that value related beliefs of important socialization agents influence the development of adolescents' academic values and that this effect is mediated through adolescents' perception of socializers' academic values. In this regard, best friends within the classroom were less focused by researchers although they become important socialization agents in adolescence. Therefore, the present study investigated the influence of friends' actual academic values on adolescents' academic values, and if this effect is mediated through adolescents' perception of friends’ actual values. All dimensions of academic values according to the expectancy-value theory were focused: intrinsic value, attainment value, utility value, and emotional cost. MethodsThe research questions were investigated based on a two-wave longitudinal study in Germany. The final sample comprised of 303 adolescents of the fifth and seventh grade with a stable, reciprocated friend. ResultsStructural equation models revealed that the friends' actual attainment value indirectly influenced the attainment value of adolescents through the friends’ perceived attainment value. The same effect pattern was found for emotional cost. For the utility value and intrinsic value, no transmission effect was observed. ConclusionThe results provide evidence that the transmission process was not uniform for all of the academic values. Results were discussed in terms of different theoretical concepts explaining the value transmission process between friends.

Young Minority Home‐Language Students’ Biased Reading Self‐Concept and Its Consequences for Reading Development

AbstractYoung students who speak a different language at home than that spoken in school (i.e., a minority home‐language) appear to exhibit a biased reading self‐concept. Importantly, this biased reading self‐concept may correspond with altered causal pathways between reading self‐concept and achievement in minority home‐language students. To test this idea, the authors examined cross‐lagged links between reading self‐concept and reading achievement in a large multiple‐group longitudinal study in Germany. Students with German (n = 885), Turkish (n = 193), or another (n = 550) home language were tested yearly in grades 1–4 on measures of reading and reading self‐concept. Despite showing lower reading achievement, students speaking a minority home language exhibited a higher reading self‐concept. Cross‐lagged paths revealed reciprocal effects between reading achievement and reading self‐concept from grade 1 to grade 2, particularly for students with German as a home language. Minority home‐language students showed significantly lower effects of reading achievement on their subsequent reading self‐concept from grade 1 to grade 2. From grade 2 onward, reading achievement predicted reading self‐concept, but not vice versa.

Personality Factors and Sick Leave Days. Evidence from a Nationally Representative Longitudinal Study in Germany.

Background: The question of whether employees’ sickness absence from the workplace depends on personality has been researched. Existing evidence mostly stems from cross-sectional studies, mainly showing that personality factors were not associated with the number of sick leave days, except for neuroticism, which was positively associated with sick leave days. Based on the above, it remains an under researched question whether intraindividual changes in personality factors are associated with changes in sick leave days. Thus, based on a nationally representative sample, the current study aimed to investigate the relationship between personality factors and sick leave days longitudinally based on a nationally representative sample of individuals in Germany. Methods: The present study used data from the German Socio-Economic Panel (GSOEP), a longitudinal survey of private households in Germany. Information from the years 2005, 2009, 2013 were used. The Big Five Inventory-GSOEP (BFI-S) was used to measure personality. Sick leave days in the preceding year were recorded. Poisson fixed effects regressions were used. Results: Adjusting for potential confounders, regressions showed that increases in neuroticism were associated with increased sick leave days. The longitudinal association between extraversion and sick leave days was marginally significant (p < 0.10). Other personality factors were not significantly associated with sick leave days. In addition, sick leave days increased with worsening self-rated health, presence of severe disability and increasing age. Conclusions: The findings of the current study highlight the association between neuroticism and sick leave days longitudinally. Further research is required to elucidate the underlying mechanisms.
