Impact of depersonalization on the course of depression: longitudinal observations from the gutenberg health study.

BACKGROUND: Symptoms of depersonalization (DP) and derealization (DR) are a risk factor for more severe impairment, non-response to various treatments, and a chronic course. In this study, we investigated the effects of DP/DR symptoms in patients with clinically significant depressive symptoms on clinical characteristics and various outcomes in a representative population-based sample with a 5-year follow-up. METHODS: The middle-aged sample comprised n = 10,422 persons at baseline, of whom n = 9,301 were free from depressive and DP/DR symptoms. N = 522 persons had clinically significant depression (PHQ-9 ≥ 10) and co-occurring DP/DR symptoms, and n = 599 persons had clinically significant depression (PHQ-9 ≥ 10) without DP/DR symptoms. RESULTS: There were substantial health disparities between persons with and without depression. These disparities concerned a wide range of life domains, including lower quality of the recalled early life experiences with the parents, current socioeconomic status, social integration (partnership, loneliness), current social and interpersonal stressors (family, work), functional bodily complaints (e.g., tinnitus, migraine, chest pain), unhealthy lifestyle, and the prevalence of already developed physical diseases. These disparities persisted to the 5-year follow-up and were exceptionally severe for depressed persons with co-occurring DP/DR symptoms. Among the depressed persons, the co-occurrence of DP/DR symptoms more than doubled the risk for recurrence or persistence of depression. Only 6.9% of depressed persons with DP/DR symptoms achieved remission at the 5-year follow-up (PHQ-9 < 5). Depression with and without co-occurring DP/DR worsened self-rated physical health significantly. The impact of depression with co-occurring DP/DR on the worsening of the self-rated physical health status was stronger than those of age and major medical diseases (e.g., heart failure). However, only depression without DP/DR was associated with mortality in a hazard regression analysis adjusted for age, sex, and lifestyle. CONCLUSIONS: The results demonstrated that DP/DR symptoms represent an important and easily assessable prognostic factor for the course of depression and health outcomes. Given the low remission rates for depression in general and depression with DP/DR in particular, efforts should be made to identify and better support this group, which is disadvantaged in many aspects of life.

Mental health state and its determinants in German university students across the COVID-19 pandemic: findings from three repeated cross-sectional surveys between 2019 and 2021.

Background: Students were at an increased risk for elevated mental symptoms during the first year of the COVID-19 pandemic compared to pre-pandemic levels. As universities remained closed much longer than anticipated, the mental burden was expected to persist through the second year of the pandemic. The current study aimed to investigate the prevalence of mental distress from 2019 through 2021 and identify risk factors for elevated mental burden, focusing on gender. Methods: We analyzed three cross-sectional online surveys among students at the University of Mainz, conducted in 2019 (n = 4,351), 2020 (n = 3,066), and 2021 (n = 1,438). Changes in the prevalence of depressive symptoms, anxiety, suicidal ideation, and loneliness were calculated using Pearson's chi-square tests and analyses of variance. Multiple linear regressions yielded associated risk factors. Results: The proportion of students with clinically relevant depressive symptoms was significantly higher during the pandemic (38.9% in 2020, and 40.7% in 2021), compared to pre-pandemic (29.0% in 2019). Similarly, more students reported suicidal ideation and generalized anxiety during the pandemic with a peak in the second pandemic year (2021). The level of loneliness was significantly higher in 2020, compared to 2019, and remained at a high level in 2021 (p < 0.001, ηp2 = 0.142). Female and diverse/open gender, being single, living alone, and being a first-year student were identified as risk factors associated with mental burden during the pandemic. Discussion: Mental burdens remained elevated among students through the second year of the pandemic and were associated with socio-demographic risk factors and pandemic-related concerns. Future research should monitor recovery and evaluate the need for psychosocial support.

Regional differences in the assessment of depressive symptoms in the former German Democratic Republic and Federal Republic of Germany.

AIM: The present study investigated regional differences in response behaviour for the Patient Health Quetionnaire-9. We tested for measurement invariance and differential item and test functioning between formerly divided East- and West-Germany: the former German Democratic Republic and Federal Republic of Germany. Diverging socialization experiences in socialist versus capitalist and collectivist versus individualist systems may affect culturally sensitive assessments of mental health. SUBJECT AND METHODS: To test this empirically, we used factor analytic and item-response-theoretic frameworks, differentiating between East- and West-Germans by birthplace and current residence based on several representative samples of the German general population (n = 3 802). RESULTS: Across all survey, we discovered slightly higher depression sum scores for East- versus West-Germans. The majority of items did not display differential item functioning-with a crucial exception in the assessment of self-harm tendencies. The scale scores were largely invariant exhibiting only small amounts of differential test functioning. Nonetheless, they made up on average about a quarter of the observed group differences in terms of effect magnitude. CONCLUSION: We explore possible causes and discuss explanations for the item-level differences. Overall, analyses of East- and West-German depressive symptom developments in the wake of reunification are feasible and statistically grounded.

The association of depressive symptoms and body weight change in midlife - Results from the Gutenberg Health Study in Germany.

BACKGROUND: The present study aimed to investigate how depressive symptoms affect bodyweight change (gain and loss), and how this association is intertwined with other psychosocial and biomedical factors in the adult general population. METHODS: In a population-based, prospective, observational single-center cohort study in the Rhine-Main-Region, Germany (Gutenberg Health Study GHS) with N = 12,220 participants, we analyzed baseline and five year follow-up data with logistic regressions separately for bodyweight gain and loss (vs. stable bodyweight). RESULTS: Overall, 19.8 % of participants gained bodyweight of at least 5 %. More female participants were affected than male participants (23.3 % vs. 16.6 %). Regarding weight loss, overall, 12.4 % lost >5 % of bodyweight; participants were more often female than male (13.0 % vs. 11.8 %). Depressive symptoms at baseline were associated with weight gain (OR = 1.03, 95 % CI = 1.02-1.05). In models controlling for psychosocial and biomedical factors, female gender, younger age, lower socioeconomic status and smoking cessation were associated with weight gain. In weight loss, there was no overall significant effect of depressive symptoms (OR = 1.01 [0.99; 1.03]). Weight loss was associated with female gender, diabetes, less physical activity, and higher BMI at baseline. Only in women, smoking and cancer were associated with weight loss. LIMITATIONS: Depressive symptoms were assessed via self-report. Voluntary weight loss cannot be determined. CONCLUSIONS: Significant weight change frequently occurs in middle to old adulthood resulting from a complex interplay of psychosocial and biomedical factors. Associations with age, gender, somatic illness and health behavior (e.g. smoking cessation) provide important information for the prevention of unfavorable weight change.

Depressive symptoms predict the incidence of common chronic diseases in women and men in a representative community sample.

BACKGROUND: Depression, the most frequent and harmful mental disorder, has been associated with specific somatic diseases as the leading cause of death. The purposes of this prospective study were to predict incident chronic diseases based on baseline depressive symptoms and to test sex-dependent effects. METHODS: In a representative German community sample of over 12 000 participants, baseline depressive symptoms (assessed using the Patient Health Questionnaire-9) were tested as a predictor of new onset of cardiovascular disease (CVD), chronic obstructive lung disease, diabetes, cancer, and migraine at 5-year follow-up. To study disease incidence, we created subsamples for each chronic disease by excluding participants who already had the respective disease at baseline. Potential confounders were included in logistic regression models and sex-specific analyses were performed. RESULTS: Controlling for demographic characteristics and loneliness, in men and women, baseline depressive symptoms were predictive of CVD, chronic obstructive lung disease, diabetes, and migraine, but not of cancer. When we additionally adjusted for metabolic and lifestyle risk factors, there was an 8% increase of chronic obstructive lung disease and migraine per point of depressive symptoms. There was a trend for CVD (4%; p = 0.053). Sex-sensitive analyses revealed trends for the relevance of depressive symptoms for CVD in men (p = 0.065), and for diabetes in women (p = 0.077). CONCLUSIONS: These findings underscore the need to implement screening for depression in the treatment of major somatic illnesses. At the same time, depressed patients should be screened for metabolic and lifestyle risk factors and for somatic diseases and offered lifestyle interventions.

Self-Criticism in the General Population: Development and Psychometric Properties of the Depressive Experiences Questionnaire Self-Criticism 4 (DEQ-SC4).

Self-criticism is a stable personality trait identified as a serious risk factor for psychopathology and weight-related health problems. Therefore, it is relevant to epidemiological research, which requires a relatively brief instrument for measuring trait self-criticism in the general population. The current study introduces a brief measure of self-criticism and presents empirical results that inform on its reliability and validity. Based on the six-item version of the Depressive Experiences Questionnaire Self-Criticism (DEQ-SC6), thorough psychometric analyses on a German representative sample (N = 2,516) were conducted and resulted in the final four-item scale: the Depressive Experiences Questionnaire Self-Criticism 4 (DEQ-SC4). Its internal consistency was good and a one-dimensional factor structure showed a good model fit. In terms of construct validity, the DEQ-SC4 was moderately linked to symptoms of depression and a non-linear association between the DEQ-SC4 and body mass index was observed, with the highest levels of self-criticism reported by underweight participants. In addition, the DEQ-SC4 showed high positive correlations with another short version of the DEQ-SC and the Big Five personality dimensions assessed in samples of university students (N = 206) and patients (N = 55), meeting theoretically-based expectations. The DEQ-SC4 therefore represents a brief screening measure of self-criticism in the general population with good psychometric properties.

[Differences in Area Specific Life Satisfaction Between East and West Germans in the Years 1991, 2006 and 2020]. / Unterschiede in der Zufriedenheit verschiedener Lebensbereiche zwischen Ost- und Westdeutschen in den Jahren 1991, 2006 und 2020.

RESEARCH: Question How did the general and area specific life satisfaction evolve between East and West Germany between 1991 and 2020? METHODS: Based on three representative surveys in the years 1991, 2006 and 2020 life satisfaction between East and West Germany was examined using mean comparison with tests of significance. The influence of relevant sociodemographic variables was calculated using Univariate Variance Analyses. RESULTS: 1991 large differences in the general life satisfaction as well as with satisfaction in the areas of living, spare time, health, finances and occupational did occur, with people in East Germany reporting to be less satisfied. These differences align during the observation time. DISCUSSION: The discrepancy in the general and area specific life satisfaction between East and West Germans did align during the last 30 years. A reason might be the improved economical living conditions in East Germany.

[Sex- and Regionalspecific Differences in Child Abuse and Violence Before the German Reunification. Results from GESA, a Multi-Cohort Study]. / Geschlechts- und regionalspezifische Unterschiede von Kindesvernachlässigung und Gewalt vor der deutschen Wiedervereinigung. Ergebnisse aus GESA, einem Multi-Kohorten Konsortium.

Results from a population-based study suggest sex-specific patterns of self-reported child maltreatment, more frequently reported in former West than East Germany. Aim of the current study was to examine these patterns in two regional samples of the former East- (SHIP, 2008 - 2012) and West German (KORA, 2013 - 2014) population. Child maltreatment was assessed using the Childhood Trauma Screener (CTS). Overall, child maltreatment was less often reported in the East German sample, compared to the West German sample. The most prominent differences were identified in self-rated emotional violence (east 6.1%, west 8.7%), physical violence (east 5.7%, west 10.3%) and physical neglect (east 10.0%, west 19.2%). However, we could not find differences in sex-specific patterns between the East and West German samples. Results were discussed within a historical context, since the events took place before the German reunification in two oppose political systems.

Physical Activity and Sedentary Behavior in University Students-The Role of Gender, Age, Field of Study, Targeted Degree, and Study Semester.

Background: Physical inactivity and sedentary behavior are modifiable risk factors for an unhealthy lifestyle in university students. The aim of this study was to identify subgroups among German university students with an increased risk for unhealthy behavior. For this purpose, differences in physical activity and sedentary behavior with respect to sociodemographic and study related factors were examined. Methods: A total of 4,351 students participated in an online survey. The amount of physical activity (metabolic equivalent of task-min/week) and the sitting time (h/day) were assessed using the German short form of the International Physical Activity Questionnaire. Differences in gender and age as well as field of study, targeted degree and study semester were analyzed using a single factorial ANOVA with Tukey correction or a Welch-ANOVA with Games-Howell correction. Results: For physical activity, significant differences were found for gender (F(2, 80.46) = 17.79, p < 0.001, ηp2 = 0.009), for field of study (F(5, 1738.09) = 7.41, p < 0.001, ηp2 = 0.01), and for study semester (F(1, 948.12) = 5.53, p < 0.05, ηp2 =0.001), but not for age and targeted degree (p > 0.05). For sedentary behavior, significant differences were found for field of study (F(5, 3816) = 5.69, p < 0.001, ηp2 = 0.01) and targeted degree (F(3, 3868) = 3.94, p < 0.01, ηp2 = 0.003), but not for gender, age and study semester (p > 0.05). Conclusion: Female students, students enrolled in "natural sciences, mathematics and informatics" and first year students appear to have an increased risk of an unhealthy lifestyle. Future research should identify barriers to and incentives of physical activity as well as reasons for high amounts of SB in sub-populations of university students. Suitable prevention and intervention programs are necessary.

Impact of the COVID-19 pandemic on depression, anxiety, loneliness, and satisfaction in the German general population: a longitudinal analysis.

PURPOSE: Cross-sectional studies found high levels of depression and anxiety symptoms, and loneliness during the first wave of the COVID-19 pandemic. Reported increases were lower in longitudinal population-based findings. Studies including positive outcomes are rare. This study analyzed changes in mental health symptoms, loneliness, and satisfaction. METHODS: Respondents of the German Socio-Economic Panel (N = 6038) were surveyed pre-pandemic (2017/2019) and during the first (June 2020) and second wave (January and February 2021) of the pandemic. Self-report screeners assessed depression and anxiety symptoms, loneliness, life and health satisfaction. Difference scores were analysed using ANCOVAs focusing on time, gender, age groups. RESULTS: Depression and anxiety symptoms and health satisfaction increased from pre-pandemic to the first wave, but declined in the second pandemic wave. Loneliness increased and life satisfaction decreased during the first and the second wave of the pandemic. Young adults and women reported more distress and loneliness, even after controlling for pre-pandemic scores, education, and income. All effects remained stable when controlling for self-reported previous diagnosis of depression or region of residence. CONCLUSION: Increases and decreases in mental health symptoms and health satisfaction showed little variation. Of concern are the strong increases of loneliness and decreased life satisfaction being important targets for interventions. Main risk factors are young age and female gender.

Study Protocol for an Ecological Momentary Assessment Study: TempRes "Temporal Variability of Risk and Resilience Factors for Suicidal Ideation".

Suicide prevention is an important public mental health issue that can be significantly brought forward by recent advances in psychological research methods and assessment. The project "TempRes" aims to harness the power of Ecological Momentary Assessment (EMA) to investigate the transdiagnostic risk and resilience factors associated with suicidal ideation drawn from the most recent research in suicide prevention and personality assessment. Participants will comprise the general population (planned: N = 100) and a risk group (patients currently in psychosomatic or psychiatric treatment) (planned: N = 50). After a comprehensive baseline assessment, they will complete up to ten short assessments per day over the course of 10 days at roughly equidistant intervals. In detail, the project examines the interplay of biography (previous suicidal behavior, experiences of childhood maltreatment), individual differences (level of personality functioning), and time-varying factors (entrapment, loneliness, mood) with respect to the emergence and fluctuation of suicidal ideation. There are two main research foci: First, the project will provide an operationalization and empirical verification of a core assumption of the integrated motivational-volitional model of suicide (IMV model). It will test whether the interaction of the time-varying predictors entrapment with loneliness (as a motivational moderator) explains reports of suicidal ideation over time. Second, it will be the first to examine personality functioning (a transdiagnostic, psychodynamically grounded conceptualization of vulnerability to psychological crises over the life span) as a time-invariant predictor of suicidal ideation assessed within an intensive longitudinal study design. The main analyses will be built on linear mixed models. The overarching aim of the project is to gain a better understanding of the psychological dynamics underlying suicidal ideation in different populations by bringing together concepts from different theoretical traditions. This will inform prevention efforts geared toward the general public as well as intervention in clinical populations.

Does social support prevent suicidal ideation in women and men? Gender-sensitive analyses of an important protective factor within prospective community cohorts.

BACKGROUND: Suicidal ideation and behavior constitute important public mental health issues. In this study, we examined whether social integration prevents suicidal ideation over time and whether gender modifies this association. METHODS: Data from the Gutenberg Health Study (population-based representative community sample in midwest Germany) and the Study of Health in Pomerania (population-based cohort study in northeast Germany) were used. Participants reporting low social support were compared to those receiving middle or high social support. Within a longitudinal study design, we calculated multiple logistic regression models including interaction terms and relevant covariates to test whether gender modified the association of social support and suicidal ideation. RESULTS: Suicidal ideation was present in 7.4% (N = 982) of the pooled cohorts' 13,290 participants. More women (8.6%, N = 565) than men (6.2%, N = 417) reported suicidal ideation. Middle or high social support was associated with a lower probability to report suicidal ideation five years later after controlling for sociodemographic factors, living situation, and cohort (OR = 0.42, 95%-CI = 0.34-0.52). Male gender was negatively related to suicidal ideation, but no statistically significant interaction of gender and social support was found (ratio of ORs = 1.00, 95%-CI = 0.73-1.35). LIMITATIONS: The number of people reporting suicidal ideation in the SHIP study was small, especially for men. Suicidal ideation was measured using a single item. CONCLUSIONS: Social support is an important protective factor in preventing suicidal ideation for both women and men. Future research should further clarify gender-specific effects of family variables in suicidal ideation and test similar predictive models of suicidal behavior.

The impact of lockdown stress and loneliness during the COVID-19 pandemic on mental health among university students in Germany.

The COVID-19 pandemic led to a shutdown of universities in Germany. In a longitudinal design, we compared mental health (depression, anxiety, somatic complaints) of university students in Germany before (June to August 2019) and in the course of the COVID-19 pandemic (June 2020) and determined the impact of pandemic-related stress and loneliness on students' mental health in self-report online surveys. We investigated 443 participants (mean age 22.8 years), among them 77% female, and 10.4% medical students. A small increase of depression mean scores was observed (F(1,420) = 5.21; p = .023), anxiety and somatic complaints have not significantly changed. There was a medium increase in loneliness from pre-pandemic scores to the pandemic situation (F(1,423) = 30.56; p < .001). Analyzed with regression analyses, current loneliness and pre-pandemic distress represented the strongest associations with mental health during the pandemic. Additionally, health-related concerns during the pandemic were associated with symptoms of depression [b = 0.21; 95%CI(0.08; 0.34); t = 3.12; p = .002], anxiety [b = 0.07; 95%CI(0.01; 0.12); t = 2.50; p = .013], somatic complaints [b = 0.33; 95%CI(0.18; 0.47); t = 4.49; p < .001], and loneliness [b = 0.10; 95%CI(0.03; 0.17); t = 2.74; p = .006]. Social stress due to the pandemic situation was associated with loneliness [b = 0.38; 95%CI(0.32; 0.45); t = 11.75; p < .001]. The results imply that university students represent a risk group for psychosocial long-term ramifications of the pandemic.

A Systematic Review on Sex- and Gender-Sensitive Research in Public Mental Health During the First Wave of the COVID-19 Crisis.

Background: Sex and gender are important modifiers of mental health and behavior in normal times and during crises. We investigated whether they were addressed by empirical, international research that explored the mental health and health behavior ramifications after the onset of the COVID-19 pandemic. Methods: We systematically searched the databases PsyArXiv, PubMed, PsycInfo, Psyndex, PubPsych, Cochrane Library, and Web of Science for studies assessing mental health outcomes (main outcomes) as well as potential risk and protective health behavior (additional outcomes) up to July 2, 2020. Findings: Most of the 80 publications fulfilling the selection criteria reflected the static difference perspective treating sex and gender as dichotomous variables. The focus was on internalizing disorders (especially anxiety and depression) burdening women in particular, while externalizing disorders were neglected. Sex- and gender-specific evaluation of mental healthcare use has also been lacking. With respect to unfavorable health behavior in terms of adherence to prescribed protective measures, men constitute a risk group. Interpretations: Women remain a vulnerable group burdened by multiple stresses and mental health symptoms. The neglect of sex- and gender-specific evaluation of aggression-related disorders, substance addiction, and mental healthcare use in the early stage represents a potentially dangerous oversight.

The relation between childhood adversity and adult obesity in a population-based study in women and men.

Childhood maltreatment has been shown to relate to adult obesity. In this epidemiological study, we investigate the association between childhood maltreatment and waist-to-height-ratio (WHtR) in a sample of the German adult population, comprising of N = 2936 participants. WHtR, an indicator for risk of obesity, was the primary outcome. Childhood maltreatment was assessed by the Childhood Trauma Screener (CTS), which assesses emotional and physical neglect, abuse as well as sexual abuse. Cohort-data were harmonized and analyzed within DataSHIELD. We used multivariable regression models to estimate the association of childhood maltreatment and WHtR at different levels of adjustments for potential confounders. Overall childhood maltreatment was associated with a higher WHtR in both sexes (women: p = 0.004, men: p < 0.001); associations were no longer significant in women after adding socioeconomic variables, but remained significant in men (p = 0.013). Additionally, we were able to identify sex specific patterns for childhood maltreatment predicting the WHtR. Emotional neglect and abuse had stronger impacts on the WHtR in women than in men, whereas physical neglect and abuse had stronger impacts in men. To our knowledge, this is the first comprehensive population-based study testing various types of childhood maltreatment with WHtR in sex-, region- and weight-stratified analyses. Future studies in clinical populations are warranted to examine U-shaped correlations between increased WHtR and childhood maltreatment.

Mental health and loneliness in the German general population during the COVID-19 pandemic compared to a representative pre-pandemic assessment.

During the pandemic, the extent of subsequent mental health strains is an important issue. A representative face-to-face survey was conducted to assess mental health consequences in the general population and to identify mental health risk factors. In a representative German sample (N = 2,503), we assessed depression and anxiety symptoms by the PHQ-4 and loneliness by a validated item. An earlier survey (2018) which used the same methods and had comparable response rates served as comparison. Scores of depression and anxiety symptoms increased from an average of 0.89 (SD = 1.21) and 0.77 (SD = 1.17) in 2018 to 1.14 (SD = 1.23) and 1.05 (SD = 1.31) in 2020. Loneliness did not increase (M = 1.35, SD = 0.68 in 2018; M = 1.38, SD = 0.78 in 2020), affecting about one in four participants to some degree. Younger participants and women were most likely to report depression, anxiety, and loneliness. As in the previous survey, social inequality factors contributed to distress and loneliness. The small overall increase of distress was consistent with recent German panel studies. In future studies and mental health interventions female sex, younger age, and socioeconomic disparities need to be considered as vulnerability factors for distress.

Bidimensional structure and measurement equivalence of the Patient Health Questionnaire-9: sex-sensitive assessment of depressive symptoms in three representative German cohort studies.

BACKGROUND: The Patient Health Questionnaire-9 (PHQ-9) has been proposed as a reliable and valid screening instrument for depressive symptoms with one latent factor. However, studies explicitly testing alternative model structures found support for a two-dimensional structure reflecting a somatic and a cognitive-affective dimension. We investigated the bidimensional structure of the PHQ-9, with a somatic (sleeping problems, fatigability, appetitive problems, and psychomotor retardation) and a cognitive-affective dimension (lack of interest, depressed mood, negative feelings about self, concentration problems, and suicidal ideation), and tested for sex- and regional-differences. METHODS: We have included data from the GEnder-Sensitive Analyses of mental health trajectories and implications for prevention: A multi-cohort consortium (GESA). Privacy-preserving analyses to provide information on the overall population and cohort-specific information and analyses of variance to compare depressive, somatic and cognitive-affective symptoms between sexes and cohorts were executed in DataSHIELD. In order to determine the dimensionality and measurement invariance of the PHQ-9 we tested three models (1 factor, 2 correlated factors, and bifactor) via confirmatory analyses and performed multi-group confirmatory factor analysis. RESULTS: Differences between sex and cohorts exist for PHQ-9 and for both of its dimensions. Women reported depressive symptoms in general as well as somatic and cognitive-affective symptoms more frequently. For all tested models an acceptable to excellent fit was found, consistently indicating a better model fit for the two-factor and bifactor model. Scalar measurement invariance was established between women and men, the three cohorts, and their interaction. CONCLUSIONS: The two facets of depression should be taken into account when using PHQ-9, while data also render support to a general factor. Somatic and cognitive-affective symptoms assessed by the PHQ-9 can be considered equivalent across women and men and between different German populations from different regions.
