[Assessing Relationship Satisfaction with Four Items? Psychometric Evaluation of the Ultra-short German Version of the Dyadic Adjustment Scale (DAS-4)]

The quality of an individual's relationship plays a central role in their personal well-being as well as their mental and physical health. Despite its great importance, there are only a few ultra-short self-report measures for the assessment of relationship quality. An exception is the four-item version of the Dyadic Adjustment Scale (DAS-4), which is gaining increasing popularity internationally. In this study, the German version of the DAS-4 was evaluated for the first time with regard to its psychometric properties in a general population sample of individuals in a romantic relationship (N=1296). In addition to satisfactory item characteristics, the unidimensional measurement model showed sufficient goodness of fit and the internal consistency was satisfactory (ω=0.80). Measurement invariance was shown for men and women based on the latent construct of the DAS-4. In line with the hypothesis, associations of the DAS-4 with gender, general life satisfaction, psychopathology and attachment styles were found, which suggests construct validity. Despite the lack of application experiences and pending psychometric analyses of the DAS-4 in relevant target groups, such as individuals in couples counselling or therapy, the four-item version can be recommended for assessing relationship satisfaction.

Psychometric evaluation of the patient health questionnaire stress scale

The "Patient Health Questionnaire (PHQ)" is a screening instrument, designed for time-efficient detection and severity assessment of depression, anxiety, and other syndromes in medical settings. Besides the questions on psychological symptoms, there are items on psychosocial functioning, on stressors and critical life events. However, for the stress items there are no psychometric properties available until now. The present study is thought to investigate item characteristics, internal consistency as well as factorial and construct validity of the stress scale of the PHQ. A representative sample of the general population of Germany was collected by a demography consulting company (USUMA, Berlin). Per random-route procedure, households and members of the households were selected. The sample was representative for the German community regarding age, gender, and education. In this investigation the following questionnaires were administered: PHQ-Stress, Questions on Life Satisfaction Modules (FLZ-M), Type-D Scale-14 (DS14). The sample included N = 2396 participants with mean age of 48.50 (SD = 17.75; range = 14 to 92) and 55.2 % being female. Reliability of the PHQ stress scale was acceptable (ω = 0.776), but some factor loadings were comparatively low. Model fit indices showed mixed results, some indicating unacceptable and some indicating acceptable fit of the 10-item stress scale of the PHQ. Correlations with related constructs demonstrated the scale's convergent validity. The results of this validation study indicate that the PHQ stress scale, which provides a one-dimensional total stress score, is a valid, good practical and reliable self-report instrument for assessing the severity of psychosocial stress.

Psychometric properties of the German version of the Pre-loss Grief Questionnaire (PG-12-R)

This study aimed to develop a German version of the revised Pre-loss Grief Questionnaire (PG-12-R) and examine its factor structure, reliability and validity. The PG-12-R was assessed in a representative German sample (N = 2,515). Of these, 362 (14.4%) reported to have a loved one suffering from an incurable disease and 352 provided full data sets. Principal component factor analysis, scree-plot and parallel analysis were conducted. Results supported a one-factor model of PG-12-R with high internal consistency. Convergent validity was confirmed by negative correlations with psychological well-being and time since diagnosis and positive correlations with a more difficult perception of circumstances surrounding the illness and unpreparedness. The German version of the PG-12-R represents a reliable and valid measurement tool of pre-loss grief. It may be used as a screening measure for high levels of pre-loss grief to identify individuals who may need additional support.

How socio-political change is associated with the number of individually reported negative life events: a population-based study using the German reunification 1989/1990 as an example

BACKGROUND

Socio-political change often leads to disruptions in employment and social networks, which can exacerbate health issues and increase mortality rates. These consequences are likely observed as an increase in negative life events (NLEs), serving as indicators of the broader social and health impacts. Using the German reunification in 1989/1990 as an example, this study investigates changes in reported numbers of NLEs and differences regarding sociodemographic characteristics.

METHODS

We used data from the population-based Study of Health in Pomerania (SHIP-START-0, SHIP-Life-Events and Gene-Environment Interaction in Depression; N=1932). Numbers of NLEs in different categories (work/financial, social/interpersonal, illness (own) and illness/death (others)) were measured retrospectively in 5-year intervals (1980-2004) using a semistructured interview. Pre-reunification and post-reunification changes were modelled using piecewise mixed-effects Poisson regressions with the 1990-1994 interval (reunification) as change point. Interactions with age, sex and education were examined.

RESULTS

The number of most NLE categories, except social/interpersonal NLEs, increased at reunification. Whereas work/financial NLEs slightly decreased post-reunification, illness-related NLEs continued to increase. Higher numbers of social/interpersonal NLEs were found with younger age. More illness-related NLEs were reported with older age, lower education (illness (own)) and by women (illness/death (others)). However, the majority reported no NLEs at reunification (68.2%-80.7%, varying by category).

CONCLUSION

Our findings suggest that although some individuals experience a marked increase in NLEs due to socio-political changes, many remain unaffected, emphasising the need for a differentiated understanding of these effects. This increase in NLEs may partly account for ongoing health and well-being disparities among countries with differing transformation histories.

Impact of Home-Based Work during the COVID-19 Pandemic on Mental and Physical Health in a German Population-Based Sample

Background: The COVID-19 outbreak necessitated physical distancing, as part of secondary prevention, at a personal and professional level. Working from home (WFH) became increasingly important. In this study, the impact of the COVID-19 pandemic restrictions on physical and mental health is investigated, compared with pre-pandemic data, and with employees who WFH and are on-site. Methods: Data from the German Saxon longitudinal study population were used. Attitudes towards WFH as well as mental and physical health assessments during the COVID-19 pandemic were examined. Comparisons were made with corresponding pre-pandemic scores and between employees WFH and on-site in 2022. Results: In total, 319 participants with equal gender distribution were included. Of those, 86 worked from home stating better organizability of their work, more time for partnership, less stress, and greater work satisfaction. Compared to pre-pandemic data, the D-score, PHQ-4, G-Score, and PHQ-SSS-8 showed a significant increase. No difference in physical or mental health between employees WFH and on-site was observed. Conclusion: In general, COVID-19 restrictions had a negative impact on mental and physical health. Although WFH is well accepted, it did not show significant health benefits.

[Anxiety, Depression, Psychological Strain and Physical Complaints before and after the Covid-19 Pandemic in a German Longitudinal Study with Adults from Saxony]

OBJECTIVE

The objective of the study was to investigate whether psychological distress increased in a German community sample from Saxony during the course of the Corona pandemic.

METHODS

In 2017/2018 and 2022, N=289 participants (54.7% female) of the Saxon Longitudinal Study were interviewed about their psychological well-being using questionnaires (PHQ-4, SSS-8).

RESULTS

There is a significant increase in complaints (anxiety, depression, psychological distress, physical complaints) compared to 2017/2018 to 2022 with effect sizes in the small and medium range (Cohens d=0.26-0.62).

CONCLUSION

Data collection was not due to the pandemic but was routine as part of an ongoing long-term study. The Covid-19 pandemic led to an increase in psychological distress and physical complaints in a Saxonian, age-homogeneous population sample.

Suicidal ideation in patients with diabetes and childhood abuse - The mediating role of personality functioning: Results of a German representative population-based study

AIMS

Suicidal ideation (SID) in patients with diabetes mellitus is increasingly acknowledged. Still, the underlying mechanisms are unclear. We examined SID prevalences in patients with diabetes, its association with different types of abuse, and a mediating effect of personality functioning.

METHODS

In a representative population sample (N = 2,515), diabetes, SID, abuse (ICAST-R), personality functioning (OPD-SQS), and depression/anxiety (PHQ-4) were assessed by self-report. Statistical analyses comprised Chi2-Tests, logistic regression and mediation analyses.

RESULTS

The prevalence of SID (21.8 %) was three fold higher in patients with diabetes compared to the general population. Abuse further increased the likelihood to report SID in diabetes patients (sexual: 48.1 % vs. 18.2 %; χ2(1) = 12.233, p <.001; emotional: 35.7 % vs. 15.7 %; χ2(1) = 10.892, p <.001). A dose-response relationship between the number of abuse experiences and SID was observed (one abuse experience: OR = 1.138, 95 %-CI [0.433, 2.990], p =.793, >2 abuse experiences: OR = 2.693, 95 %-CI [1.278, 5.675], p =.009). Impaired personality functioning had an indirect effect on the association between emotional abuse and SID (b = 0.25, 95 %-CI [0.037, 0.551]).

CONCLUSIONS

Diabetes patients experience increased SID prevalences, especially those with emotional or sexual abuse. In individuals with a history of emotional abuse, impaired personality functioning partly explained SID and should therefore be considered and addressed in this patient group.

To what extent are psychological variables considered in the study of risk and protective factors for suicidal thoughts and behaviours in individuals with cancer? A systematic review of 70 years of research

Psychological variables substantially shape the risk of suicidal thoughts and behaviours (STBs). However, it is unclear to what extent they are considered in individuals with cancer. We synthesized the quantitative research landscape concerning psychological risk/protective factors of STBs in the (psycho-) oncological context. This pre-registered review (PROSPERO-ID CRD42022331484) systematically searched the databases PubMed/Medline, CINAHL, PsycInfo, Cochrane Library, and Web of Science (as well as the grey literature and preprints). Risk of bias (RoB) was estimated using the ROBINS-I tool. Of 11,159 retrieved records, 319 studies were eligible for inclusion. Of those, 163 (51.1%) had investigated psychological factors (affective: n = 155; social: n = 65; cognitive: n = 63; personality/individual differences: n = 37; life events: n = 6), in a combined 3,561,741 participants. The most common STBs were suicidal ideation (n = 107) or death wishes (n = 20) rather than behaviour (suicide deaths: n = 26; attempts: n = 14). Most studies had a serious RoB. Thus, a large body of research investigated STBs in cancer patients/survivors, but it rarely aligned with the theoretical or clinical developments in suicide research. We propose a conceptual model of STBs in cancer delineating moderation and mediation effects to advance the integration of the fields, and to inform future research and practice.

Early Childhood Care in the Former East Germany and Mental Stress in Adulthood

BACKGROUND

It is still debated in Germany whether early childhood care outside the family might cause mental stress in adulthood. In the German Democratic Republic (GDR-the former East Germany before unification), children were often cared for outside the family from a very early age.

METHODS

To determine the relation between early childhood care outside the family and mental stress in adulthood, we carried out a survey among 1575 persons who were born and socialized in the GDR. They were classified into four care groups according to the age at which they were first cared for outside the family. Associations with depressiveness, somatization disorders, and anxiety disorders in adulthood were tested with logistic regression analysis. Care group-specific prevalences of experiences of abuse and neglect in childhood were estimated with analysis of variance.

RESULTS

Comparisons of persons cared for outside the family before the age of three, or from the age of three onward, with persons cared for within the family in their preschool years did not reveal any difference with respect to depressiveness (odds ratio [OR] = 0.95; 95% confidence interval [0.58; 1.55]; OR = 1.05 [0.63; 1.74]), somatization disorders (OR = 1.11 [0.74; 1.67]; OR = 1.09 [0.71; 1.66]), or anxiety disorders (OR = 0.87 [0.46; 1.64]; OR = 1.12 [0.59; 2.10]). Nor were there any intergroup differences with respect to experiences of abuse and neglect. Certain features of the very small group of children who had long-term care outside the family are discussed in the article.

CONCLUSION

No relation was found between early-childhood care in day-care centers in the GDR and mental stress in adulthood. The data were too sparse for any conclusions about specific aspects of care outside the home (e.g., quality or child-rearing norms).

Social support in older adults: Validation and norm values of a brief form of the Perceived Social Support Questionnaire (F-SozU K-6)

BACKGROUND

Social relations are crucial for maintaining physical and mental health across the life span. As social roles, networks and needs change with age a valid assessment of social support in older adults and age-specific norms are necessary. The present work aims to [1) assess the level of social support in individuals > 60 years of the general German population, [2) evaluate the brief six-item form of the Perceived Social Support Questionnaire (F-SozU K-6) in this age group and to [3) provide age-specific norm values.

METHODS

We analyze data of N = 706 people representative for the German population collected in 2021. To assess social support, we used the F-SozU K-6. We tested for selectivity, item difficulty, internal consistency, construct and factor validity, as well as factorial invariance. Additionally, we assessed correlations and associations with depression, loneliness, and sociodemographic factors. Furthermore, we reported norm values for respondents > 60 years.

RESULTS

Participants > 60 years reported a mean level of 23.97 (SD = 4.82) of social support. Results of the CFA confirmed a very good model fit. Measurement invariance across sex and age was shown. Associations with ADS and LS-S supported construct validity. Multiple regression analysis showed that female sex, increasing age, having a partner, and a higher equivalized household income were associated with higher levels of social support.

CONCLUSION

The F-SozU K-6 is a reliable and economical tool to assess perceived social support in older adults. Norm values for individual > 60 years are provided.

Depression, anxiety, and health-related quality of life in normal weight, overweight and obese individuals with diabetes: a representative study in Germany

OBJECTIVE

Diabetes in the course of lifetime is related to a higher risk for mental disorders. The present study addresses the comparison of individuals with diabetes and non-diabetic individuals in depressive symptoms, generalized anxiety symptoms, and health-related quality of life. Furthermore, mediator effect of BMI and health-related quality of life (HRQOL) on the association between diabetes, depression, and generalized anxiety was analyzed.

METHODS

In this cross-sectional study, the three questionnaires PHQ-9, GAD-7, EQ-5D-5L were measured in a representative sample of the German population (N = 2386). In addition, the presence of diabetes and BMI were assessed via self-report.

RESULTS

There were higher values in depressive and anxiety symptoms as well as lower score in HRQOL in individuals with diabetes compared to non-diabetic individuals. Obese individuals with diabetes showed the highest rates in depressive symptoms and generalized anxiety as well as lowest score in HRQOL. With regard to the mediator analyses, association between diabetes, depressive symptoms, and anxiety symptoms is partially mediated by the BMI and fully mediated by the HRQOL.

CONCLUSIONS

In conclusion, individuals with diabetes have an increased risk in the development of depressive and anxiety symptoms as well as lower health-related quality of life. Future research and strategies in the public health policies among individuals with diabetes should take into account that the association between diabetes, depression, and anxiety is mediated by BMI and HRQOL.

Cutoff scores of the Eating Disorder Examination-Questionnaire for the German population

OBJECTIVE

The Eating Disorder Examination-Questionnaire (EDE-Q) is one of the most widely used self-report measures for the assessment of eating disorder (ED) symptomatology. However, proposed cutoff scores that may indicate the presence of an ED have been heterogeneous. Therefore, the current study derived cutoff scores from two large samples: one representative for the German population and one composed of persons with EDs at admission to inpatient treatment.

METHOD

Receiver operating characteristic analysis was used with the EDE-Q global score as independent variable and group (controls: n = 2519, patients: n = 2038) as dependent variable. These analyses were also conducted separately with the patient group divided into persons with anorexia nervosa (AN; n = 1456), bulimia nervosa (BN; n = 370), and other EDs (n = 212) and after matching groups for age and sex distribution.

RESULTS

The EDE-Q global score discriminated well between controls and patients (AUC >91%, sensitivity >.84, specificity >.79). A score of 1.6 discriminated best between controls and patients in general and persons with AN in particular. Optimal thresholds for discriminating between controls and persons with BN and other EDs ranged between scores of 1.8 and 2.4.

DISCUSSION

In the German population, cutoff scores between 1.6 and 2.4 may be used to screen for the presence or absence of an ED or evaluate treatment outcome, with slightly higher cutoff scores for persons with BN and other EDs than for persons with AN.

PUBLIC SIGNIFICANCE

Questionnaire scores have little value when it is unclear which scores indicate the likely presence of an ED, as such scores can be used to estimate the prevalence of or screen for EDs in the general population and evaluate outcome at the end of ED treatment. The current study indicates a score around 2 on the EDE-Q as an optimal threshold for this.

Abusive head trauma: The body of the iceberg - A population-based survey on prevalence and perpetrators

BACKGROUND

Research on abusive head trauma (AHT) is usually research on clinically identified cases, while population-based studies, having the potential to identify cases of shaking that did not end with hospital admission, are missing to date.

OBJECTIVE

Thus, we aimed to assess the prevalence of AHT and associated risk factors in a representative sample of the German population.

PARTICIPANTS AND SETTING

We conducted a cross-sectional, observational study in Germany from July to October 2021. Using different sampling steps including a random route procedure, a probability sample of the German population was generated. The final sample consisted of 2503 persons (50.2 % female, mean age: 49.5 years).

METHODS

Participants were asked about sociodemographic information in a face-to-face interview and whether they had been ever responsible for the care of an infant and whether they had ever performed potential harmful methods including shaking to calm it, intimate partner violence (IPV) and adverse childhood experiences (ACEs) using a questionnaire.

RESULTS

In total, 1.4 % of women (N = 18) and 1.1 % of men (N = 13) reported to have at least once shaken an infant to calm it. Ever having used a potential harmful parenting method in calming an infant was reported by 4.9 % of women (N = 61) and 3.1 % (N = 39) of men. No gender differences were seen. A low income, living with someone under 16 in the household and victimization and perpetration of IPV and ACEs are associated with increased risks of shaking and other potential harmful methods to calm an infant.

CONCLUSIONS

Our data suggest that despite better knowledge on the dangers of shaking, the percentage of women that shake infants might be higher than previously thought. Also, intimate partner violence and ACEs are key risk factor for shaking and harmful parenting behaviors in general. This has important implications for future prevention programs.

Prolonged grief disorder in ICD-11 and DSM-5-TR: differences in prevalence and diagnostic criteria

Background

Prolonged grief disorder (PGD) was recently included as a disorder in the ICD-11 and DSM-5-TR. Although both classification systems use the same name, the criteria content, and diagnostic approach vary. This study aimed to estimate the respective prevalence of PGDICD-11 and PGDDSM-5-TR and examine the diagnostic agreement while varying the diagnostic algorithm of PGDICD-11 (bereavement vs. symptom period; varying number of accessory symptoms).

Methods

A representative sample of the German general population (N = 2,509) was investigated, of which n=1,071 reported the loss of a close person. PGD symptoms were assessed with the Traumatic Grief Inventory - Self Report Plus (TGI-SR+).

Results

The point prevalence of PGD among the bereaved varied between 4.7%-6.8%, depending on the criteria and diagnostic algorithm. The prevalence of PGDDSM-5-TR was significantly lower than the prevalence of PGDICD-11. The diagnostic agreement between both criteria sets was substantial and increased after the number of accessory symptoms for PGDICD-11 was increased from one to three. The most common symptoms were intrusive thoughts/images related to the deceased person, longing for the deceased person, and difficulty accepting the loss.

Conclusion

The results demonstrate that the prevalence of PGD significantly varies depending on the application of the diagnostic algorithm and criteria. PGD affects a substantial proportion of the general population and should be addressed by healthcare providers. However, applying the minimum ICD-11 criteria could lead overestimating the prevalence. Therefore, further harmonizing the ICD-11 and DSM-5-TR criteria and diagnostic algorithm for PGD seems appropriate.

Gender differences in the prevalence of mental distress in East and West Germany over time: a hierarchical age-period-cohort analysis, 2006-2021

PURPOSE

Mental distress has become a major public health concern. Temporal trends in psychological distress are complex and depend on numerous factors. In this study, we examined age-period-cohort effects for mental distress including gender and German region over a 15 years' time span.

METHODS

Data on mental distress from ten cross-sectional surveys of the general German population, covering the years from 2006 to 2021, was used. Hierarchical age-period-cohort analyses including gender and German region as predictors were performed to disentangle age, period, and cohort effects. The Patient Health Questionnaire-4 was used as a brief screener for mental distress.

RESULTS

We found significant period and cohort effects, with peek values for mental distress in the years 2017 and 2020 and for the oldest birth cohort (born before 1946). Age did not affect mental distress when cohort- and period effects as well as gender and German region were considered. An interaction effect for gender and the German region was found. Women in West Germany reported significantly higher mental distress compared to women in East Germany. Compared to men, women reported the highest prevalence in both regions.

CONCLUSION

Important political events as well as major crises can lead to an increase of mental distress in societies. Furthermore, an association between birth cohort and mental distress could be linked to socialization effects of that certain time, causing traumatic experiences or a specific coping style within this cohort group. Prevention and intervention strategies could benefit from acknowledging structural differences linked to period and cohort effects.

Attachment styles and healthcare utilization: exploring the role of the patient-doctor relationship

BACKGROUND

With the purpose of improving healthcare, past research has examined the link between healthcare utilization and attachment. It is suggested that an individual's attachment style influences both the quality of their patient-physician relationship and healthcare utilization patterns. Nevertheless, most studies concentrate on the individual aspect, overlooking the dyadic dimension; specifically, the investigation of how insecure attachment relates to health behavior within patient-physician relationships. This gap leaves the role of the patient-doctor relationship in this process unclear. Therefore, to elucidate this complex interplay, we hypothesized that the correlation between attachment and healthcare utilization is mediated by the quality of the patient-physician-relationship.

METHOD

Participant selection was based on electoral districts, a random-route procedure, and the Kish selection grid. The participants were visited by a trained interviewer who collected psychometric and sociodemographic information. Participants answered the Experiences in Close Relationships-Revised questionnaire (ECR-RD8) and the Patient-Doctor Relationship Questionnaire (PDRQ-9). Additionally, participants were asked about their healthcare utilization. The final sample consisted of N = 2.275 participants.

RESULTS

In average the participants reported consulting their primary health care practitioner M(SD) = 4.44 (4.76) times in the past 12 months. Generally, the participants rated the quality of the relationship with their primary health care practitioner close to "totally appropriate" (M = 4.12 ± .69). The degree of insecure attachment manifested towards the lower extremity of the scale. The total effect of the mediation analyses was significant. Regardless, the indirect effect indicated a trend result with minimal effect sizes.

CONCLUSION

The findings of the current study bridged the gap between attachment styles and healthcare utilization. Nonetheless, our results suggested insufficient support for the mediating role of the primary care physician in the relationship between attachment style and healthcare utilization. Considering the characteristics of the sample, this outcome may not apply in a clinical context. However, further research is needed to shed light in the revealed trends and indicate implications.

The effects of effort-reward imbalance on the job, overcommitment, and income on life satisfaction in Germany from a longitudinal perspective

BACKGROUND

The effort-reward imbalance at work model offers a theoretical and analytical framework to estimate the subjective perception of work-related stress. High demands and low rewards in return can harm mental and physical health, well-being, and life satisfaction. According to the theory, overcommitment partially explains why employees endure such straining jobs. In Germany, cultural and economic aspects of labor differ between East and West. Incomes are lower in the East, while work centrality there is higher. In this article, the effects of effort-reward imbalance, overcommitment, and income on life satisfaction as well as their interactions with region were analyzed to gain a clearer picture of regional disparities regarding life satisfaction and the generality of this work stress model in Germany.

METHODS

Data from 3848 participants from 2006 to 2011 of the German Socio-Economic Panel were analyzed. Within-between models were estimated, including fixed and random effects of the continuous form of effort-reward imbalance to predict subjective life satisfaction. Time-variant covariates - e.g., overcommitment or income - as well as time-constant variables - e.g., region, sex, education - were integrated. Differences in regional labor markets between East and West Germany were considered.

RESULTS

Easterners exhibited higher imbalances and overcommitment than Westerners, indicating worse working conditions. Higher imbalances and overcommitment were associated with lower life satisfaction within and between participants, whereas for income only random effects were supported. While region did not moderate the effect of work stress, East Germans' life satisfaction benefitted more from a higher income.

CONCLUSION

The importance of internal work structures in terms of recognition, adequate pay, advancement opportunities, or time pressure were underlined. As compared to the West, Easterners' life satisfaction benefitted more from higher income but not more from a lower imbalance or lower overcommitment. The interplay between materialistic and nonmaterialistic rewards at work should be focused on in the future.

To trust or not to trust in the thrall of the COVID-19 pandemic: Conspiracy endorsement and the role of adverse childhood experiences, epistemic trust, and personality functioning

RATIONALE

Conspiracy endorsement is a public health challenge for the successful containment of the COVID-19 pandemic. While usually considered a societal phenomenon, little is known about the equally important developmental backdrops and personality characteristics like mistrust that render an individual prone to conspiracy endorsement. There is a growing body of evidence implying a detrimental role of adverse childhood experiences (ACEs) - a highly prevalent developmental burden - in the development of epistemic trust and personality functioning. This study aimed to investigate the association between ACEs and conspiracy endorsement in the general population, specifically questioning a mediating role of epistemic trust and personality functioning.

METHODS

Based on cross-sectional data from a representative German survey collected during the COVID-19 pandemic (N = 2501), we conducted structural equation modelling (SEM) where personality functioning (OPD-SQS) and epistemic trust (ETMCQ) were included as mediators of the association between ACEs and conspiracy endorsement. Bootstrapped confidence intervals (5000 samples, 95%-CI) are presented for all paths.

RESULTS

ACEs were significantly associated with conspiracy endorsement (β = 0.25, p < 0.001) and explained 6% of its variance. Adding epistemic trust and personality functioning as mediators increased the explained variance of conspiracy endorsement to 19% while the direct association between ACEs and conspiracy endorsement was diminished (β = 0.12, p < 0.001), indicating an indirect effect of personality functioning and epistemic trust in the association between ACEs and conspiracy endorsement. Fit indices confirmed good model fit.

CONCLUSIONS

Establishing an association between ACEs and conspiracy endorsement further increases the evidence for early childhood adversities' far-reaching and detrimental effects. By including epistemic trust and personality functioning, these findings contribute to a deeper understanding of the underlying mechanisms in the way that ACEs may be associated with conspiracy endorsement.

Chronic stress in old age: Psychometric properties of the Trier Inventory of Chronic Stress (TICS), based on a general population sample aged 60 and over

BACKGROUND

Chronic stress results from an imbalance of personal traits, resources and the demands placed upon an individual by social and occupational situations. This chronic stress can be measured using the Trier Inventory for Chronic Stress (TICS). The aims of the present study are to test the factorial structure of the TICS in a sample of elderly people, report its psychometric properties, and give norm values for elderly individuals.

METHODS

The TICS was answered by N = 790 healthy participants aged 60 to 99 years. The sample was selected by random-route sampling. Confirmatory factor analyses applying Robust Maximum Likelihood estimations (MLM) tested model fit and factorial structure. Reliability estimations and norm values are reported.

RESULTS

Confirmatory factor analyses replicate the reported nine-factor as well as the higher-order two-factor solution. Additionally, a general one-factor model was identified. All models provide acceptable model fit, with model comparison fit statistics corroborating the superiority of the nine-factor model. Reliability coefficients were good to very good.

CONCLUSION

The TICS can now also be used reliably in samples with elderly people. Its proposed nine-factor structure could be factorially validated and results in good scale reliability. Norm values for an elderly sample are now available.

Further Evidence for a Dimensional Latent Structure of Health Anxiety: Taxometric Analyses of the Whiteley Index Based on Two German Representative Samples

Health anxiety is an intricate part of illness anxiety and somatic symptom disorder. Based on convenience samples, two out of three available studies indicate that it is a dimensional rather than a categorical construct. Using two representative datasets, this study investigates whether previous results can be clarified. Conventional taxometric analyses as well as comparison curve fit indices (CCFI) profile analyses (MAMBAC and MAXSLOPE procedures) were calculated with two datasets of the German adult population assessing the Whiteley Index (WI-14, N = 2,072; WI-7, N = 2,498). Mean CCFIs indicated a dimensional structure for both the WI-7 (mean CCFI = 0.42, mean CCFI profile = 0.40) and the WI-14 (mean CCFI = 0.44, mean CCFI profile = 0.32). The results support and extend previous findings by strongly suggesting a dimensional distribution of health anxiety in the general population. Implications for research and practice comprise the adoption of a dimensional description of psychopathology as well as transdiagnostic treatment approaches.

Variables associated with oral health-related self-efficacy - results of a cross-sectional study

BACKGROUND

Oral health-related self-efficacy (OH-SE) is pivotal for oral health and is associated with other oral-health related variables, such as dental fear and anxiety (DF/A) and dental hygiene behaviors (DHB). This study attempts to analyze associations between OH-SE and oral healthrelated variables in a German population to extend previous research by analyzing whether OH-SE can be predicted by these variables, as this might contribute to the development of treatment interventions.

METHODS

OH-SE, DF/A, oral health-related quality of life (OHRQoL), self-perceived dental condition, satisfaction with general health, DHB, and socioeconomic status were assessed as a part of the Saxon Longitudinal Study in an adult sample (n = 309, 56.3% female, all Saxon secondary school 8th graders in 1987). The associations of OH-SE with these variables were examined by means of correlation, multiple linear regression analyses, and group comparisons. Significance (p), standardized regression coefficients (β), and effect size (Cohen's d) were calculated.

RESULTS

The correlation analyses revealed increased OH-SE to be accompanied by low levels of DF/A, high levels of OHRQoL, high levels of self-perceived dental condition, increased satisfaction with general health and socioeconomic status (all r ≥ 0.142; all p ≤ 0.013). In the regression analysis, OH-SE was mainly predicted by self-perceived dental condition and satisfaction with general health (R2 = 0.157) as well as by daily frequency of toothbrushing, OHRQoL, and socioeconomic status on a trend-level basis. In the group comparisons OH-SE was lower in participants with moderate for manifest DF/A and higher in individuals with higher OHRQoL, better self-perceived dental condition, increased satisfaction with general health, increased daily frequency of toothbrushing, more dental appointments, and above-average socioeconomic status (trend level; all t ≥ 1.57; p ≤ 0.059).

CONCLUSIONS

In this cross-sectional study, high levels of OH-SE were mainly predicted by general health as well as self-perceived dental condition. It was also associated with decreased DF/A, increased DHB, higher OHRQoL, and higher socioeconomic status. Future research should analyze these associations in longitudinal designs to address whether interventions focusing on adherence to good DHB improve (dental) health and thus OH-SE. This might be a promising approach, particularly in relation to the treatment of DF/A.

Self-rated physical health predicts mortality in aging persons beyond objective health risks

Previous studies on self-rated health and mortality have usually not differentiated between physical and mental health, respectively have not considered physical diseases. This study aims to determine self-rated physical and mental health from middle to old age, examine associations with mortality adjusted for objective risk factors and assess effect modification by gender. In a large population-based sample (N = 14,993 at baseline), self-rated physical and mental health were rated separately by a single-item. Associations to mortality were modelled by Cox regressions, adjusting for potential confounding variables. Most participants rated their physical (79.4%), resp. mental health (82.3%) as good. Poor self-rated physical health was lowest in the youngest group (19.6%, age 35-44), and highest in midlife (29.1%, age 55-64). Poor self-rated mental health was lowest among the oldest (18.5%), and highest from 45 to 54 years (29.3%). Poor self-rated physical, but not mental health was predictive of mortality when adjusting for objective risk factors. Male gender and poor self-rated physical health interacted (RERI 0.43 95%-CI 0.02-0.85). Self-rated physical health was best in the youngest and worst in the midlife group, this pattern was reversed regarding self-rated mental health. Poor self-rated physical, but not mental health was predictive of mortality, adjusting for objective risk factors. It was more strongly predictive of mortality in men than in women. Poor subjective physical health ratings, should be taken seriously as an unfavorable prognostic sign, particularly in men.

Explorative analyses on spatial differences in the desire for social distance toward people with mental illness in a diverging city

Introduction

Stigma is an individual and societal process based on attitudes and power and relates to both spatial disparities and social distinction. In this study, we examined differences in desire for social distance toward people with mental illness within a city using social and spatial information.

Methods

ANOVAs and Scheffé post-hoc tests analyzed varying desires for social distance toward people with mental illness within Leipzig (East Germany). Joint Correspondence Analyses (JCA) explored correspondences between desire for social distance, socio-economic status, age, life orientation, social support, duration of living in Leipzig, and shame toward having a mental illness in five city districts of Leipzig in LIFE study participants (by Leipzig Research Center for Civilization Disease, data collected 2011-2014 and 2018-2021, n = 521).

Results

Stigma varied among Leipzig's districts (F(df = 4) = 4.52, p = 0.001). JCAs showed that a higher desired social distance toward people with mental illness corresponded with spatial differences, high levels of pessimism, high shame of being mentally ill, low social support, low socio-economic status, and older age (75.74 and 81.22% explained variances).

Conclusion

In terms of stigma, where people with mental illness live matters. The results identified target groups that should be addressed by appropriate intervention and prevention strategies for mental health care.

Adverse childhood experiences increase the risk for low perceived social participation and health-related quality of life in a large-scale population-based study in Germany

BACKGROUND

Adverse childhood experiences (ACEs) are highly prevalent and increase the risk for long-term adverse health outcomes. Next to well-known ACE-associated risks for morbidity, recent research is increasingly invested in exploring pathways towards health, overall functioning, and partaking in society following early adversity.

OBJECTIVES

Thus, this study aims to assess the association between latent classes of ACEs with perceived social participation and health-related Quality of Life (QoL) in a large population-based sample and to explore potential moderators of these associations.

METHOD

A representative sample of the German population (N = 2531; Mage = 48.7; 51 % women) was cross-sectionally investigated for ACEs, social participation (KsT-5), and health-related QoL (EuroQol-5D-5L). Latent Class Analysis (LCA) was performed to derive groups with similar ACE patterns. Multiple regression analyses were used to investigate the association of latent classes of ACEs with social participation and health-related QoL and to explore potential moderators.

RESULTS

Four distinct latent classes of ACEs were identified; "no/low ACEs" (N = 1968, 77.8 %); "household-dysfunction" (N = 259, 10.2 %), "child abuse and neglect" (N = 188, 7.4 %), and "polyadversity" (N = 116, 4.6 %). Compared to participants in the no/low ACE class, those in the ACE-exposed classes showed overall lower levels of perceived social participation and health-related QoL. The polyadversity class showed lower levels of social participation compared to the two other ACE-exposed classes. Chronic stress, living with a partner, education, current job/educational involvement, and gender were found to moderate these associations in exploratory analyses.

CONCLUSIONS

This study shows people exposed to ACEs to have a higher risk for lower perceived social participation and lower health-related QoL - an increased risk, however, is not a deterministic uninventable fortune. Reduction of chronic stress, fostering of social support, and educational and vocational paths as interventional targets are discussed to enable those with precarious starting conditions to partake in society.

[Life events related to the German reunification and their associations with psychosocial health in a sample of northeast Germany]

Objectives: The aim of the present study was to investigate (1) the type and frequency of reported life events of the East German population related to the German reunification and (2) their associations with psychosocial health. Methods: Data of 2247 participants of the Study of Health in Pomerania was used.These qualitative responses were analysed using quantitative content analysis. Their associations with subjective physical and mental health, optimism, social support, depressive symptoms, and chronic stress were examined. Results: Eight life event categories were identified (education, employment-related changes, material changes, new opportunities, personal life events, politics, separations, reunifications). Especially, experiencing new opportunities was associated with a higher level of optimism as well as a lower level of depressive symptoms and chronic stress. Conclusions: In this study, events frequently described in the literature (e.g., employment-related and social changes) were confirmed and systematized.The observed associations of these events with psychosocial factors should be examined further in future studies.

Mental resources, mental health and sociodemography: a cluster analysis based on a representative population survey in a large German city

BACKGROUND

Mental resources such as optimism and social support are important to face different stressors. The aim of this study is to identify groups in the population that are similar in terms of their mental resources.

METHODS

For this purpose, a randomly selected general population community sample was used, representative for the city of Leipzig, Germany. In a two-stage process, three clusters were identified using hierarchical cluster analysis and the K-means method and then tested with a multinomial logistic regression analysis for differences in sociodemographic characteristics.

RESULTS

Three clusters were identified which vary in their extent of social support and optimism. In distinguishing between those with higher and lower (medium or poor) mental resources, male gender, unemployment, being born abroad and low household income are risk factors for having fewer mental resources. Internal migrants from West Germany and persons with children at home have a higher chance of being in the type with good mental resources. The groups with medium and lower mental resources differ significantly only by variables living with a partner and employment.

CONCLUSION

Our results indicate that good mental resources are associated with good mental health. Special mental health care programs, focusing in particular on the needs of vulnerable groups with poor mental resources within a society, should be implemented.

Prevalence and Correlates of Dry Eye in a German Population Sample

PURPOSE

In this cross-sectional survey, we assessed the prevalence of dry eye disease (DED) in a representative German population sample. In addition, we examined the associations between DED, health-related quality of life (HRQoL), and level of fatigue. Finally, we further validated the German version of the Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire and present norm data of the German population.

METHODS

A random sample of German residents aged 16 years and older was recruited between October and December 2021. All participants completed the SPEED, Short Form 36, and Multidimensional Fatigue Inventory 20 questionnaires.

RESULTS

Of the 2495 participants who completed the survey, 450 (21.6%; 95% confidence intervals 20.0-23.1) reported a SPEED total score of ≥4, indicating a positive screening for DED. DED was significantly more common in women and older age. Participants who screened positive for DED reported significantly higher levels of fatigue and lower values in all domains of HRQoL. A receiver operating characteristic curve of the SPEED was generated using an ophthalmologist's diagnosis. The area under the curve was estimated to be 0.886 (95% confidence intervals 0.858-0.913). A cutoff score ≥4 seemed to be appropriate as an indicator of DED. Cronbach's α was excellent (0.95).

CONCLUSIONS

DED is common in the German population. We confirmed associations with sex, age, HRQoL, and fatigue level, indicating a high burden of DED. The German version of the SPEED is a valid instrument for the assessment of DED symptoms.

Measuring personality functioning with the 12-item version of the OPD-Structure Questionnaire (OPD-SQS): reliability, factor structure, validity, and measurement invariance in the general population

Background

The assessment of personality functioning is at the core of current dimensional models of personality disorders. A variety of measures from different clinical and research traditions aim to assess basic psychological capacities regarding the self and others. While some instruments have shown reliability and validity in clinical or other selected samples, much less is known about their performance in the general population.

Methods

In three samples representative of the German adult population with a total of 7,256 participants, levels of personality functioning were measured with the short 12-item version of the Operationalized Psychodynamic Diagnosis - Structure Questionnaire (OPD-SQS). We addressed questions of factor structure, reliability, validity, factorial invariance, and provide norm values.

Results

Confirmatory factor analysis indicated a satisfactory to good model fit. OPD-SQS models were mostly unaffected by variables such as gender, age, or measurement time. As expected, personality functioning was associated with general psychopathology as well as indices of occupational functioning.

Conclusion

The OPD-SQS is a viable measure to assess personality functioning in the general population.

Insomnia symptoms in adulthood. Prevalence and incidence over 25 years

OBJECTIVE/BACKGROUND

Despite its high prevalence, little information is available about the course of insomnia symptoms over the life span. In this study, we analyzed the self-reported insomnia symptoms of the general population over more than 20 years, covering young up to middle adulthood.

PATIENTS/METHODS

Data from waves 12 to 32 of the Saxon Longitudinal Study (1996-2021), were analyzed. Based on data from the 12th wave, n = 115 adults (48 men (41.7%), 67 women (58.3%), Mage = 23.59, SD = 0.59) completed the G-Score Item #3 in the following 18 waves, thus forming the basis for our analyses. The G-Score Item #3 reads "In the last 12 months, have you had the following complaints? Please indicate how often they occurred - Insomnia". The G-Score Item #3 was dichotomized using a cut-off score of 2, and prevalence and incidence rates were calculated by gender.

RESULTS

The minimum prevalence rate was 23.48% (Mage = 32.11, SD = 0.40), and the maximum was 47.83% (Mage = 48.43, SD = 0.64), indicating an increase in insomnia symptoms with age. In most cases, no evidence was found for gender differences in prevalence rates. The incidence rates were 10.43% for the 1st year of follow-up and 8.7% for the 5th year and 6th year of follow-up, respectively.

CONCLUSIONS

This study provides further evidence for the high prevalence rates of insomnia symptoms in the general population. As this study is the first epidemiological study of insomnia symptoms based on a single-item (screening) instrument, it should be rather seen as an extension than a replication of previous study findings.

Recalled parental rearing behavior shapes mental health after preterm birth: Evidence from the Gutenberg Prematurity Study

Associations of preterm birth with later-life mental distress are well-established. A research gap concerns the role of psychosocial factors such as the family context. This study investigated associations of recalled parental rearing behavior with both preterm birth characteristics and psychological symptom burden later in life. Based on birth registry data of the Mainz University Hospital in Germany (infants born between 1969 and 2002) and using a selection algorithm, a cohort study comprising four gestational age (GA) strata was conducted (≥ 37 weeks: n = 138; 33-36 weeks: n = 132; 29-32 weeks: n = 106; ≤ 28 weeks: n = 132). Participants underwent a medical examination and completed standardized questionnaires. We investigated differences in dimensions of recalled parental rearing behavior according to GA and tested pre-/perinatal stress indicators and recalled parental rearing behavior as statistical predictors of depression and anxiety symptoms later in life. Lower GA was associated with more recalled emotional warmth and overprotection. Recalled emotional warmth was associated with fewer depression and anxiety symptoms, while recalled overprotection co-occurred with more depression symptoms. The findings indicate the relevance of parental rearing behavior for the offspring's mental health. As preterm birth implicates stress for the whole family requiring adaptive parental behavior, the latter could be an important modifiable risk factor.

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.

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

BACKGROUND

Epidemiological research on the prevalence of traumatic events and PTSD has shown that there are significant differences between countries, due to their different history and socialization processes. In the case of Germany, this is particularly relevant. Germany was divided into two states from 1949 to 1990. This study examines the prevalence of traumatic events and PTSD in the formerly divided East and West Germany.

METHODS

For the prevalence of traumatic events, we used data from four representative surveys (years 2005, 2007, 2008, and 2016) with a total of N = 9,200 respondents. For the analyses of PTSD prevalence, we used data from three representative surveys (years 2005, 2007, 2008) with a total of N = 6676 respondents. We compared different birth cohorts, persons living in the former West vs. East Germany, and the application of different diagnostic criteria using a chi-square test.

RESULTS

The overall one-month prevalence rate for PTSD was 3.4% (3.0% for men and 3.8% for women). We found significant differences in the occurrence of traumatic events between genders, different age cohorts as well as between people who live in East and West Germany. Significant differences in the prevalence of PTSD can only be observed for different age cohorts. Most of the age effects are due to traumatic events related to World War II (WWII). Prevalence rates for PTSD were higher when the diagnostic criterions of the DSM-V were applied compared to the criterions of the DSM-IV.

CONCLUSIONS

Our data suggests that socio-political factors may need to be considered when accounting for differences in occurrence rates of traumatic events, but not for prevalence rates of PTSD, between East and West Germany. People who have experienced WW II have a higher risk of suffering from PTSD. Future epidemiological trauma research should take historical and regional peculiarities of countries into account.

Hedonic Overeating-Questionnaire: Exploring interactive effects between wanting, liking, and dyscontrol on body mass index

The Hedonic Overeating-Questionnaire is a brief self-report measure for the trait assessment of liking (pleasure to eat; consummatory reward component), wanting (food craving; anticipatory reward component), and dyscontrol (loss of control over eating). In the original validation study, higher scores on each of the three subscales related to higher body mass index (BMI). However, theories on food reward and self-regulation suggest that overeating and obesity may also result from interactions between these aspects. Therefore, we reanalyzed the data of the original, cross-sectional study (N = 2504, 53% female) and explored whether liking, wanting, and dyscontrol scores interactively predicted BMI. Indeed, there was a significant interaction effect Wanting × Dyscontrol on BMI such that higher dyscontrol scores related to higher BMI, particularly at high wanting scores. The other two-way interactions and the three-way interaction were not significant. Results do not support certain theories on food reward (e.g., the incentive-sensitization theory of addiction and its application to obesity), which would suggest an interactive effect between liking and wanting on BMI. However, they do support dual systems models of self-regulation that suggest that overeating and obesity result from an interplay of strong bottom-up impulses (here: wanting) and weak top-down control (here: dyscontrol).

Supplementary data analyses for the associations of child maltreatment and diabetes in adulthood and the mediating effect of personality functioning

In this article, supplementary data analyses regarding the association between different types of child maltreatment (CM) and diabetes as well as mediation analyses examining the role of personality functioning are provided (original research article: 'Associations of different types of child maltreatment and diabetes in adulthood - the mediating effect of personality functioning: findings from a population-based representative German sample') (Zara et al., 2023). Analyses are based on a representative sample of the German population (N = 5,041). Data was acquired through a representative survey conducted by the independent research institute USUMA Berlin. CM, personality functioning, a diabetes diagnosis as well as symptoms of depression and anxiety were assessed using self-report questionnaires (CTQ, OPD-SQS, PHQ-4). Correlation analyses for all used variables were conducted. Independent t-tests were performed to examine whether symptoms of depression and anxiety are elevated in patients with diabetes and CM (compared to no CM). Regarding the odd ratios (ORs) calculated to examine the association between types of CM and diabetes as well as mediation analyses investigating the role of personality functioning in these associations, sensitivity analyses with persons ≥ 30 years are provided. The additional analyses are intended to add to the body of research showing that patients with diabetes experience symptoms of depression and anxiety more frequently compared to the general population (Kampling and Kruse, 2020; Chireh et al., 2019; Smith et al., 2018), examine the association between different types of CM and diabetes, and explore the role of personality functioning in the association between CM and diabetes.

Efficacy of high-intensity versus low-intensity psychoanalytically oriented long-term treatments and determinants of outcome: individual participant data Meta-analysis of Long-term Analytic treatment Studies (MeLAS)

INTRODUCTION

Long-term psychodynamic/psychoanalytic psychotherapy (LTPP) is a prevalent treatment option for complex mental disorders. Yet, little is known about the role of treatment intensity in LTPP. We present a study protocol for a systematic review and individual participant data (IPD) meta-analysis aggregating and analysing individual data from randomised and quasi-experimental trials by meta-analysis. The purpose is to (1) determine the treatment effectiveness of LTPP with low versus high intensity (up to 2 weekly sessions vs three or more), (2) compare their joint effectiveness to shorter therapies and treatments as usual, (3) identify predictors and moderators of treatment outcomes and (4) determine reciprocal relationships between different outcome domains (symptomatic and structural/personality change) over the courses of LTPP.

METHODS AND ANALYSIS

We include studies from (randomised controlled trial, RCT) and quasi-experimental trials, where at least one condition was LTPP of high or low frequency. Long-term treatment is defined as ≥1 year or ≥50 sessions. To be eligible studies must include a standardised outcome measure of symptoms (global or disorder specific) with at least one proof of reliability. The primary outcome is symptom reduction (global or specific), secondary outcome criteria are reliable change, remission, functional capacities, personality, personality functioning and interpersonal pathology. Relevant studies will mainly be identified by searching relevant databases: PubMed, PsycINFO (via EBSCO), Web of Science (via Elsevier), Chochrane's Central Register of Controlled Trials (via Wiley). Risk of bias will be evaluated in line with the Cochrane assessments tools for quasi-experimental trials and RCTs, respectively.

ETHICS AND DISSEMINATION

Aggregation of data from primary trials collected based on ethics votes. Dissemination into clinical practice via open access publications of findings.

Quality of life after pediatric cancer: comparison of long-term childhood cancer survivors' quality of life with a representative general population sample and associations with physical health and risk indicators

BACKGROUND

This study aimed to compare the quality of life (QoL) reported by childhood cancer survivors (CCS) drawn from a cohort of the German Childhood Cancer Registry with a representative general population sample and, within CCS, to test associations between QoL and health behavior, health risk factors, and physical illness.

METHODS

CCS (N = 633, age at diagnosis M = 6.34 (SD = 4.38), age at medical assessment M = 34.92 (SD = 5.70)) and a general population sample (age-aligned; N = 975) filled out the EORTC QLQ-C30. Comparisons were performed using General linear models (GLMs) (fixed effects: sex/gender, group (CCS vs. general population); covariates: age, education level). CCS underwent an extensive medical assessment (mean time from diagnosis to assessment was 28.07 (SD = 3.21) years) including an objective diagnosis of health risk factors and physical illnesses (e.g., diabetes and cardiovascular disease). Within CCS, we tested associations between QoL and sociodemographic characteristics, health behavior, health risk factors, and physical illness.

RESULTS

CCS, especially female CCS, reported both worse functional QoL and higher symptom burden than the general population. Among CCS, better total QoL was related to younger age, higher level of education, being married, and engaging in active sports. Both health risk factors (dyslipidemia and physical inactivity) and manifest physical illnesses (cardiovascular disease) were associated with lower total QoL.

CONCLUSIONS

In all domains, long-term CCS reported worse QoL than the comparison sample. The negative associations with risk factors and physical illnesses indicate an urgent need for long-term surveillance and health promotion.

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.

Functional Somatic Disorders, Their Subtypes, and Their Association With Self-Rated Health in the German General Population

OBJECTIVE

The heterogeneous conceptualizations and classifications of persistent and troublesome physical symptoms impede their adequate clinical management. Functional somatic disorder (FSD) is a recently suggested interface concept that is etiologically neutral and allows for dysfunctional psychobehavioral characteristics as well as somatic comorbidity. However, its prevalence and impact are not yet known.

METHODS

We analyzed 2379 participants (mean age = 48.3 years, 52.5% female) from a representative German community survey using operationalized FSD criteria. These criteria defined FSD types based on somatic symptom count, type, and severity assessed by the Bodily Distress Syndrome Checklist. In addition, the associations of those types with health concerns, comorbidity, psychological distress, and self-rated health were determined.

RESULTS

There were four clearly demarcated groups with no relevant bothering symptoms, with one or with few bothering symptoms from one organ system, and with multiple bothering symptoms from at least two organ systems. Psychological distress, health concerns, and comorbidity steadily increased, and self-rated health decreased according to the number and severity of symptoms. Somatic symptom burden, health concerns, and comorbidity independently predicted self-rated health, with no interaction effect between the latter two.

CONCLUSIONS

Our data support an FSD concept with two severity grades according to persistent and troublesome symptoms in one versus more organ systems. The delimitation of subtypes with psychobehavioral characteristics and/or with somatic comorbidity seems useful, while still allowing the demarcation of a group of participants with high symptom burden but without those additional characteristics.

Epidemiology of intimate partner violence perpetration and victimisation in a representative sample

AIMS

Intimate partner violence (IPV) is a major global public health problem. Although IPV is known to be frequent and perpetration and victimisation often co-occur, large representative samples assessing both, male and female IPV perpetration and victimisation and overlaps are missing to date. Thus, we aimed to assess victimisation and perpetration and its overlap in physical, sexual, psychological and economic IPV in a representative sample of the German population.

METHODS

We conducted a cross-sectional, observational study in Germany from July to October 2021. Using different sampling steps including a random route procedure, a probability sample of the German population was generated. The final sample consisted of 2503 persons (50.2% female, mean age: 49.5 years). Participants were asked about socio-demographic information in a face-to-face interview and experience of physical, psychological, sexual and economic IPV using a questionnaire.

RESULTS

A significant proportion of persons in Germany reporting IPV are both perpetrator and victim for each IPV form. The biggest overlap between perpetration and victimisation was seen for psychological IPV. Major risk factors for IPV perpetration only were male gender and adverse childhood experiences (ACEs) while major risk factors for IPV victimisation only comprised of female gender, low household income and ACEs. In the perpetration and victimisation group, gender differences were less significant; older age and lower household income did increase the likelihood of combined perpetration and victimisation.

CONCLUSIONS

We have identified a significant overlap of perpetration and victimisation of IPV in the German population for men and women. However, men are at much higher risk to perpetrate IPV without being a victim. Further research and the development of adapted approaches for contexts of overlapping IPV are necessary.

Headache impact and socioeconomic status: findings from a study of the German Migraine and Headache Society (DMKG)

BACKGOUND

Headache disorders are not only among the most prevalent, they are also among the most disabling disorders worldwide. This paper investigates the association between headache impact on daily life and the socioeconomic status (SES) of headache sufferers.

METHODS

Data stem from a random general population sample in Germany. Respondents who reported having headache for at least a year and were aged ≥ 18 years were included in the study. A standardized questionnaire addressing headache and headache treatment was filled in during the face-to-face survey. The impact of headache on daily life was measured using the German version of the Headache Impact Test (HIT-6).

RESULTS

Higher headache impact was found in low and medium SES compared to high SES. After adjustment for sociodemographics, headache-related factors (analgesic use, headache duration, headache frequency, migraine diagnosis), depressive symptoms, physical inactivity and obesity, an increased odds ratio of having higher headache impact in low SES compared to high SES was found: OR = 1.83, 95% CI [1.43, 2.23], p = .014. When the interactions "SES*obesity", "SES*depressive symptoms", and "SES*physical inactivity" were added, the results showed a significant interaction effect of "SES*obesity". Obese persons with low SES were 3.64 times more likely to have higher headache impact than non-obese persons with low SES. No significant differences between obese and non-obese persons were found in the medium and high SES groups.

CONCLUSIONS

SES is an important factor that should not be neglected in headache awareness campaigns and headache treatment. Longitudinal studies are needed in the future to investigate whether lifestyle interventions, such as weight reduction, can help to reduce headache impact in people in lower SES.

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.

Efficacy and moderators of short-term psychodynamic psychotherapy for depression: A systematic review and meta-analysis of individual participant data

BACKGROUND

Short-term psychodynamic psychotherapy (STPP) is frequently used to treat depression, but it is unclear which patients might benefit specifically. Individual participant data (IPD) meta-analyses can provide more precise effect estimates than conventional meta-analyses and identify patient-level moderators. This IPD meta-analysis examined the efficacy and moderators of STPP for depression compared to control conditions.

METHODS

PubMed, PsycInfo, Embase, and Cochrane Library were searched September 1st, 2022, to identify randomized trials comparing STPP to control conditions for adults with depression. IPD were requested and analyzed using mixed-effects models.

RESULTS

IPD were obtained from 11 of the 13 (84.6%) studies identified (n = 771/837, 92.1%; mean age = 40.8, SD = 13.3; 79.3% female). STPP resulted in significantly lower depressive symptom levels than control conditions at post-treatment (d = -0.62, 95%CI [-0.76, -0.47], p < .001). At post-treatment, STPP was more efficacious for participants with longer rather than shorter current depressive episode durations.

CONCLUSIONS

These results support the evidence base of STPP for depression and indicate episode duration as an effect modifier. This moderator finding, however, is observational and requires prospective validation in future large-scale trials.

Parental stress and physical violence against children during the second year of the COVID-19 pandemic: results of a population-based survey in Germany

BACKGROUND

Parents and caregivers belonged to those with the highest burdens during the COVID-pandemic. Considering the close link between parental stress and child maltreatment, identifying families with high parental stress is of utmost importance to prevent violence against children. Within this study, we thus aimed to investigate the interplay of parental stress, changes in parental stress, and physical violence against children during the second year of the COVID-pandemic on an exploratory level.

METHODS

We conducted a cross-sectional, observational study in Germany from July to October 2021. By using different sampling steps, a representative probability sample of the German population was generated. A subsample of these participants with children under the age of 18 was included for analysis within this study (N = 453, 60.3% females, M_age = 40.08; SD = 8.53).

RESULTS

Higher parental stress levels were associated with more physical violence against children, higher levels of own experiences of child maltreatment, and mental health symptoms. An increase in parental stress during the pandemic was associated with female sex, the use of physical violence against children, and parental experience of child maltreatment. Parents who have ever used physical violence against their children have been characterized by higher parental stress levels, a stronger increase in parental stress during the pandemic, own experience of child maltreatment, mental health symptoms and sociodemographic characteristics. Higher parental stress levels, a stronger increase of parental stress during the pandemic, having pre-existing psychiatric disorders, and parental experience of child maltreatment predicted an increased use of physical violence against children during the pandemic.

CONCLUSIONS

Our results underscore the importance of parental stress for the risk of physical violence against children, more so in times of overall increased stress due to the pandemic and underline the need for low threshold support for families at risk in times of crises.

[Psychometric Evaluation of a Single-Item-Screener for Sleep Disturbances]

OBJECTIVE

Sleep disturbances are one of the most prevalent health complaints in the general population. Thus, the need for validated screening instruments and prevention measures is high. The aim of the current study is to evaluate a potential single-item screening instrument and therefore, contribute to an improved early detection.

METHODS

Data from Saxony Longitudinal Study (SLS) is being analyzed. Based on data of 32nd wave (n=321, 172 women, 149 men, M age=48.42, SD=0.64), the G-Score Item #3 ("Have you had the following complaints in the last 12 months? Please indicate how often they occurred. - sleeplessness"), a potential screening instrument, is psychometrically evaluated. A Receiver Operating Characteristic (ROC)-Analysis is calculated to assess the predictive validity of the G-Score Item #3.

RESULTS

Retestreliability for the G-Score Item #3 is 0.70 (p<0.001). Correlation with the Jenkins Sleep Scale (JSS) was r=0.79 (p<0.01). The area under the curve (AUC) is 0.92, providing evidence for a very good predictive validity.

DISCUSSION AND CONCLUSION

This study provides evidence for the use of the G-Score Item #3 as a screening instrument for sleep disturbances by showing good psychometric properties and brevity.

[Communicating about Parental Cancer with Minor Children: Necessity, Burden, and Issues from a Parent's Perspective]

BACKGROUND

In addition to coping with their own stresses, parents of minor children with cancer face the difficult task of communicating the diagnosis and its effects to their children. The aim of this study is to examine parents' perceptions of conversations with their children and to identify key topics for psychosocial support.

METHODS

Using a questionnaire, N=82 cancer patients with N=162 minor children were asked about their experiences when talking to their children about the disease.

RESULTS

Communication about the disease was perceived as necessary by most parents. This was especially the case for older children. With 143 out of 162 children (88.3%), the conversation was held. Of the 82 parents interviewed, 16.5% felt no burden as a result of the talks, 15.2% reported a very high burden. The feeling of not being able to protect the children was perceived as particularly stressful.

DISCUSSION

Most parents consider communication with the children to be important and seek it. However, many find this difficult, e. g. because they actually want to protect their children. Additional stress can be caused by questions from the children to which the parents cannot give an answer.

CONCLUSION

Psychosocial support can be helpful here. Experiences discussed by parents can help other parents in similar situations.

Self-regulation profiles reflecting distinct levels of eating disorder and comorbid psychopathology in the adult population: A latent profile analysis

OBJECTIVE

Previous research showed that individuals with eating disorders (EDs) can be subtyped by their levels of psychopathology and self-regulation abilities. However, nothing is known about whether self-regulation abilities are solely suited to depict the heterogeneity in ED and comorbid psychopathology in nonclinical samples. Therefore, this study sought to explore self-regulation profiles and their ability to discriminate ED, depression and anxiety disorders, and personality dysfunction in the adult population.

METHODS

Within a German representative sample, N = 2391 adults (18-92 years) were examined using latent profile analysis to identify profiles based on established cognitive and emotional self-regulation scales including attention control, cognitive reappraisal, and difficulties in identifying feelings. Profiles were validated with ED, depression, anxiety, and personality dysfunction measures.

RESULTS

The final solution selected as best balancing goodness of fit and interpretability included four profiles-High-Functioning, Moderate-Functioning, Dysregulated, and Alexithymic-with high explanatory power of R²  = .99. Profiles were characterized primarily by differences in difficulties in identifying feelings followed by differences in attention control and differed significantly regarding ED, depression and anxiety disorders, and personality dysfunction, with the Dysregulated profile showing the most unfavorable correlates.

CONCLUSIONS

This study uniquely revealed that low cognitive and emotional self-regulation were indicators for ED, depression, anxiety, and personality dysfunction in the adult population. Future research should investigate whether the identified profiles predict the development of ED and comorbid psychopathology longitudinally.

PUBLIC SIGNIFICANCE

Individuals with eating disorders present with difficulties in cognitive and emotional self-regulation, likely maintaining their symptoms. This representative study in the German adult population sought to build profiles based on cognitive and emotional self-regulation that differed in eating disorder and comorbid psychopathology. We discuss the potential to detect individuals with elevated eating disorder and comorbid psychopathology based on the identified profiles in nonclinical settings.

Associations of different types of child maltreatment and diabetes in adulthood - the mediating effect of personality functioning: Findings from a population-based representative German sample

PURPOSE

This study aimed to examine the role of personality functioning in the association between various types of child maltreatment (CM) (sexual, physical, and emotional abuse as well as physical and emotional neglect) and diabetes in adulthood.

METHODS

Analyses are based on representative data of the German population (N = 5,041) from 2016 to 2019. Self-report questionnaires assessed diagnosis of diabetes, child maltreatment (CTQ), personality functioning (OPD-SQS), and symptoms of depression/anxiety (PHQ-4). Odd ratios were calculated to examine the association between CM and diabetes, and mediation analyses including PHQ-4 as covariate were conducted to examine the role of personality functioning.

RESULTS

All CM types significantly elevated the odds of having diabetes in adulthood. Personality functioning mediated the association between abuse and diabetes (sexual: b = 0.012, 95% CI [.002, 0.022], P_M = 25.0%, physical: b = 0.009, 95% CI [.001, 0.017], P_M = 12.0%, and emotional: b = 0.013, 95% CI [.002, 0.024], P_M = 59.8%), but not between neglect and diabetes.

CONCLUSIONS

CM is associated with an increased risk of diabetes, with personality functioning being a relevant mediator for CM abuse types. Hence, by focusing on CM prevention and considering impaired personality functioning in diabetes treatment, diabetes self-management and health behavior could be improved.

Screening for loneliness in representative population samples: Validation of a single-item measure

BACKGROUND

Loneliness is a highly relevant public mental health issue. This work presents the validation of a single-item measure of loneliness and its subjective experience: "I am frequently alone/have few contacts". It can be used in large-scale population surveys where an economical assessment is of key importance.

METHODS

Data was drawn from two representative German population surveys conducted in early and late 2020 (combined N = 4,984; 52.9% women; age: M = 48.39 years (SD = 17.88)). We determined the prevalence of loneliness in men and women across different age groups. In order to test concurrent validity, bivariate correlation analyses and Chi-square tests were performed. Convergent and discriminant validity were tested by investigating intercorrelations of the single-item measure of loneliness with another loneliness measure, other mental health outcomes, and associations with sociodemographic characteristics.

RESULTS

Based on the single-item measure, 23.4% of participants reported some degree of loneliness, 3.4% among them severe loneliness. Comparisons with the LS-S showed similar prevalence rates of loneliness. A moderately positive relationship between the two loneliness measures was found by bivariate correlation analysis (ρ = .57, p < .001), but results indicated only weak convergent validity. Construct validity was supported by associations with depressive symptoms, anxiety symptoms, satisfaction with life, household size, and partnership.

CONCLUSIONS

Loneliness is frequently reported in the general population. The single-item measure of loneliness is suitable as a brief screening measure in population-based assessments.
