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.

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.

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.

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.

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.

[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.

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.

Experienced Childhood Maltreatment in a Sample of Pedophiles: Comparisons With Patients of a Psychosomatic Outpatient Clinic and the General Population.

BACKGROUND: Adverse childhood events have a lasting impact on mental health. Studies on patients with pedophilia focus on traumatic events as sexual abuse in their childhood, in which further childhood maltreatment is rarely described. AIM: In addition to previous studies on patients with pedophilia that focus on traumatic events as sexual abuse, we further investigate different types of childhood maltreatment. METHODS: We compared 3 samples using the Childhood Trauma Questionnaire: patients with pedophilia, psychotherapy outpatients, and general population (GP). Descriptive analyses were conducted for prevalence rates. To assess statistical differences between the samples concerning retrospective childhood trauma, we conducted t-tests and a multivariate analysis of variance. Binary logistic regression analyses were conducted to identify predictors of childhood maltreatment. OUTCOMES: Emotional and sexual abuse was associated with pedophilic sexual preference. RESULTS: Significant differences of experienced childhood maltreatment were found between the samples with the patients with pedophilia reporting the highest rates. Psychotherapy outpatients reported more childhood maltreatment than the GP except for sexual abuse. CLINICAL IMPLICATIONS: Our results speak to a burdened and stressful childhood of patients with pedophilia; a fantasized, sexualized world in an abusive and neglecting childhood may function as a refuge and lead to "psychic withdrawal." STRENGTHS & LIMITATIONS: This is the first study comparing a small sample of patients with pedophilia with psychotherapy outpatients and a representative sample of the GP. The use of an established and standardized questionnaire of childhood maltreatment represents a strength. However, the questionnaire's exclusive focus on abuse and neglect represents a limitation as it fails to examine other sources of adverse childhood experiences (eg, intrafamily relationships or loss of a parent). CONCLUSION: A better understanding can help establish more effective treatment and prevention programs for patients with pedophilia. Marx CM, Tibubos AN, Brähler E, et al. Experienced Childhood Maltreatment in a Sample of Pedophiles: Comparisons With Patients of a Psychosomatic Outpatient Clinic and the General Population. J Sex Med 2020;17:985-993.

The association between recalled parental rearing behavior and depressiveness: a comparison between 1st immigrants and non-immigrants in the population-based Gutenberg Health Study.

BACKGROUND: Studies in immigrant youth have suggested differences in parenting patterns by immigration status. Knowledge of variation in recalled parenting pattern and its distinctive impact on mental health in adult immigrants, however, is limited. Therefore, the purpose of the current study was to investigate similarities and differences in recalled maternal and paternal rearing behavior and its association with depressiveness in adult 1st generation immigrants compared to non-immigrants. METHODS: Seven hundred and forty-three 1st generation immigrants (M = 57.4, SD = 10.1 years) and 6518 non-immigrants (M = 60.3, SD = 10.7 years) participated in a population-based study. Regarding countries of origin, the largest subgroups were immigrants from Eastern-Europe, Former-SU, and Arabic-Islamic countries. All participants completed the ultra-short version of The Recalled Parental Rearing Behavior-questionnaire and the PHQ-9 assessing depressiveness. Multiple linear regressions with depressiveness as outcome variable were analyzed separately for each facet of parental rearing behavior adjusting for socio-demographic and migration-related variables. RESULTS: In addition to differences in depressiveness and socioeconomic status, 1st generation immigrants recalled both their mothers and fathers as more controlling and overprotecting than non-immigrants. Parental emotional warmth was negatively associated with depressiveness across all groups. The relationship between parental control, respectively parental rejection and depressiveness, however, varied in direction and severity between the groups. CONCLUSION: The results support the notion that parental warmth is a universal protective factor against depressiveness, whereas the impact of parental control on mental health might be more culturally influenced. Analyses point to the importance of considering the unique contribution of fathers' rearing behavior on mental health, particularly in immigrant samples.

Noise annoyance predicts symptoms of depression, anxiety and sleep disturbance 5 years later. Findings from the Gutenberg Health Study.

BACKGROUND: Cross-sectional studies have shown that noise annoyance is strongly associated with mental distress, however, its long-term effects on mental health is unknown. We therefore investigated whether noise annoyance predicts depression, anxiety and sleep disturbance in a large, representative sample 5 years later. METHODS: We investigated longitudinal data of N = 11 905 participants of the Gutenberg Health Study, a population-based, prospective, single-centre cohort study in mid-Germany (age at baseline 35-74 years). Noise annoyance was assessed at baseline and 5-year follow-up (sources: road traffic, aircraft, railways, industrial, neighbourhood indoor and outdoor noise; and day vs. nighttime). Depression, anxiety and sleep disturbance were assessed using the Patient Health Questionnaire-9 and Generalized Anxiety Disorder-2. Participants suffering from depression, anxiety or sleep disturbance at baseline were excluded from the respective multivariate analyses of new onset at follow-up. RESULTS: General noise annoyance remained stable. Daytime noise annoyance predicted new onset of depressive, anxiety symptoms (also nighttime annoyance) and sleep disturbance (beyond respective baseline scores). Additional predictors were female sex, lower age and low socioeconomic status (SES). Regarding specific sources, daytime baseline aircraft annoyance predicted depression and anxiety. Sleep disturbance was most consistently predicted by neighbourhood annoyance (baseline and follow-up) and follow-up annoyance by aircraft (night) and road traffic (day and night). CONCLUSIONS: We identified current and past noise annoyances as risk factors for mental distress and sleep disturbance. Furthermore, women, younger adults and those with lower SES are particularly susceptible to noise annoyance. Our results indicate the need to provide regulatory measures in affected areas to prevent mental health problems.

New onset of depression in aging women and men: contributions of social, psychological, behavioral, and somatic predictors in the community.

BACKGROUND: Based on the vulnerability-stress model, we aimed to (1) determine new onset of depression in individuals who had not shown evidence of depression at baseline (5 years earlier) and (2) identify social, psychological, behavioral, and somatic predictors. METHODS: Longitudinal data of N = 10 036 participants (40-79 years) were evaluated who had no evidence of depression at baseline based on Patient Health Questionnaire (PHQ-9), no history of depression, or intake of antidepressants. Multivariate logistic regression models were used to predict the onset of depression. RESULTS: Prevalence of new cases of depression was 4.4%. Higher rates of women (5.1%) than men (3.8%) were due to their excess incidence <60 years of age. Regression analyses revealed significant social, psychological, behavioral, and somatic predictors: loneliness [odds ratio (OR) 2.01; 95% confidence interval (CI) 1.48-2.71], generalized anxiety (OR 2.65; 1.79-3.85), social phobia (OR 1.87; 1.34-2.57), panic (OR 1.67; 1.01-2.64), type D personality (OR 1.85; 1.47-2.32), smoking (OR 1.35; 1.05-1.71), and comorbid cancer (OR 1.58; 1.09-2.24). Protective factors were age (OR 0.88; 0.83-0.93) and social support (OR 0.93; 0.90-0.95). Stratified by sex, cancer was predictive for women; for men smoking and life events. Entered additionally, the PHQ-9 baseline score was strongly predictive (OR 1.40; 1.34-1.47), generalized anxiety became only marginally, and panic was no longer predictive. Other predictors remained significant, albeit weaker. CONCLUSIONS: Psychobiological vulnerability, stress, and illness-related factors were predictive of new onset of depression, whereas social support was protective. Baseline subclinical depression was an additional risk weakening the relationship between anxiety and depression by taking their overlap into account. Vulnerability factors differed between men and women.

Declining Sexual Activity and Desire in Men-Findings From Representative German Surveys, 2005 and 2016.

BACKGROUND: Surveys have indicated an increase of sexual activity in aging men; recently, however, a decrease of sexual activity has been reported in young men. AIM: To assess (i) sexual activity and desire and their determinants across the age range in a population-based male sample and (ii) their changes over 11 years. METHODS: A representative survey of men (N = 1,095) 18 to 93 years old from 2016 was compared with a survey from 2005 (N = 1,106 men) with the same age range. Samples were drawn from the German population at random using standardized sampling procedures. Questions were filled out by participants in the presence of a trained interviewer. Sexual activity was compared using logistic regression with the factors survey (2005 vs 2016), living with a partner (yes vs no), and age. Frequency of sexual desire was compared using analysis of covariance with the factors survey (2005 vs 2016), living with a partner (yes vs no), and the covariate age. OUTCOMES: Sexual activity was assessed as having been intimate with someone in the past year; frequency of sexual desire was evaluated within the past 4 weeks. RESULTS: The great majority of men cohabiting with a partner in 2016 was sexually active and indicated sexual desire until 70 years of age; half did so at an older age. Across the age range, men living without a partner reported considerably less sexual activity and desire. Compared with 2005, fewer men reported living with a partner. The overall proportion of men reporting sexual activity deceased from 81% to 73% in 2016 and absent sexual desire increased from 8% to 13%. CLINICAL TRANSLATION: The findings highlight the relevance of living with a partner for sexual activity and desire. We advocate using a measure of sexual activity that encompasses many variants of intimate behavior. STRENGTHS AND LIMITATIONS: Large and methodologically comparable population-based samples were compared. However, interpretations are limited by the absence of longitudinal data. We did not assess the effect of having a partner living elsewhere. CONCLUSION: Sexual activity and desire decreased, especially in the young and middle-age groups. The decrease of men living with a partner contributed to this decreased sexual activity and desire. There was a generation effect, with younger and middle-age men living without a partner becoming less sexually active and experiencing less desire compared with the previous survey. The findings unveil changes in sexual activity and desire in a short time span. Beutel ME, Burghardt J, Tibubos AN, et al. Declining Sexual Activity and Desire in Men-Findings From Representative German Surveys, 2005 and 2016. J Sex Med 2018;15:750-756.

Loneliness in the general population: prevalence, determinants and relations to mental health.

BACKGROUND: While loneliness has been regarded as a risk to mental and physical health, there is a lack of current community data covering a broad age range. This study used a large and representative German adult sample to investigate loneliness. METHODS: Baseline data of the Gutenberg Health Study (GHS) collected between April 2007 and April 2012 (N = 15,010; 35-74 years), were analyzed. Recruitment for the community-based, prospective, observational cohort study was performed in equal strata for gender, residence and age decades. Measures were provided by self-report and interview. Loneliness was used as a predictor for distress (depression, generalized anxiety, and suicidal ideation) in logistic regression analyses adjusting for sociodemographic variables and mental distress. RESULTS: A total of 10.5% of participants reported some degree of loneliness (4.9% slight, 3.9% moderate and 1.7% severely distressed by loneliness). Loneliness declined across age groups. Loneliness was stronger in women, in participants without a partner, and in those living alone and without children. Controlling for demographic variables and other sources of distress loneliness was associated with depression (OR = 1.91), generalized anxiety (OR = 1.21) and suicidal ideation (OR = 1.35). Lonely participants also smoked more and visited physicians more frequently. CONCLUSIONS: The findings support the view that loneliness poses a significant health problem for a sizeable part of the population with increased risks in terms of distress (depression, anxiety), suicidal ideation, health behavior and health care utilization.

Peer attachment, specific patterns of internet use and problematic internet use in male and female adolescents.

Problematic internet use may lead to serious psychosocial dysfunction. Recent studies have found comparable prevalence in both male and female adolescents. We pursue the neglected questions how male and female adolescents differ regarding their patterns of internet use and how gender, peer attachment and patterns of use are related to pathological internet use. In 2410 adolescents (1307 girls and 1103 boys) aged 12-18 years from different types of school we assessed peer attachment, frequency and use of eight specific applications and indicators of pathological internet use. Three patterns of internet use, 'social'; 'sex and games" and 'functional' were identified and connections between variables were modeled by ordered sequences of regression. We found that problematic internet use-sex and games as well as social usage-was more prevalent in boys. Insecure peer attachment predicted problematic internet use in both sexes. Also, excessive usage of internet games and sex mediated the influence of peer attachment insecurity on problematic internet use, but only for boys. Our study identified that adolescents with insecure peer attachment are at higher risk for problematic internet use. With regard to specific types of internet use, the consumption of online games and sex was identified as risk factor in boys with increasing age. Further studies are needed to understand and possibly subgroup problematic internet use behavior in girls. Our findings suggest that increasing the quality of peer relationships may be promising approach in the prevention and treatment of problematic internet use.

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.

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.

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.
