The unique Legionella longbeachae capsule favors intracellular replication and immune evasion.

Legionella longbeachae and Legionella pneumophila are the most common causative agents of Legionnaires' disease. While the clinical manifestations caused by both species are similar, species-specific differences exist in environmental niches, disease epidemiology, and genomic content. One such difference is the presence of a genomic locus predicted to encode a capsule. Here, we show that L. longbeachae indeed expresses a capsule in post-exponential growth phase as evidenced by electron microscopy analyses, and that capsule expression is abrogated when deleting a capsule transporter gene. Capsule purification and its analysis via HLPC revealed the presence of a highly anionic polysaccharide that is absent in the capsule mutant. The capsule is important for replication and virulence in vivo in a mouse model of infection and in the natural host Acanthamoeba castellanii. It has anti-phagocytic function when encountering innate immune cells such as human macrophages and it is involved in the low cytokine responses in mice and in human monocyte derived macrophages, thus dampening the innate immune response. Thus, the here characterized L. longbeachae capsule is a novel virulence factor, unique among the known Legionella species, which may aid L. longbeachae to survive in its specific niches and which partly confers L. longbeachae its unique infection characteristics.

Collective loneliness: The impact of the social network on loneliness and depression during the coronavirus pandemic in older Europeans.

OBJECTIVES: We examined the impact of the social network before the coronavirus pandemic on loneliness and depressed mood during the pandemic in older European individuals, and how these relationships differ between different European countries. METHODS: Data of N = 19,999 persons (age: M = 69.18 years; 51% female) from the pan-European longitudinal survey of health, ageing and retirement in Europe, interviewed between October 2019 and March 2020 (Wave 8) and between June and August 2020 (Corona Questionnaire 1), were used. To test the models we employed path analyses, controlling for age, gender, education, and occupational status. Models were also run separately in collectivistic (Romania, Slovenia, Croatia, and Greece) and individualistic (Netherlands, Belgium, Denmark, and France) country groups. RESULTS: A larger social network before the pandemic reduced the probability of an increase in loneliness and depression. The negative association between social network size and increase in loneliness was stronger in collectivist countries than in individualist ones. Moreover, an increase in loneliness increased the probability of feeling depressed. CONCLUSIONS: It appears that pre-pandemic social networks served as a buffer to negative mental health consequences of the pandemic in older Europeans. In fact, this association was stronger in collectivist than for individualist countries. While this underscores the importance of social connectedness, it also stresses the vulnerability of socially isolated individuals regarding loneliness and depression. Future work should thus focus on supporting social networks in older adults.

A "Self-Milieux" perspective on help-seeking: examining the impact of a person's sociocultural background on help-seeking in people with untreated depressive symptoms.

BACKGROUND: Mental illness is a global concern and the leading cause of years lived with disability. Research on help-seeking behaviour has focused on individual factors, but there is still much unexplained variance. Suggesting complex interactions between determinants of human behaviour a new framework called Self-Milieux is proposed to represent a person's sociocultural background. The article introduces a statistical approach to determine Self-Milieux and exemplarily examines its predictive validity for health-related research. METHODS: Self-Milieux are determined through a two-stage clustering method based on the determinants socioeconomic status and self-construal profile. Descriptive analyses are used to compare Self-Milieux characteristics. Hierarchical binary logistic regression models test the association between Self-Milieux and help-seeking behaviour, while controlling for socioeconomic status as an established predictor. RESULTS: The sample size was N = 1535 (Mage = 43.17 and 64.89% female participants). Average depression severity was M = 12.22, indicating mild to moderate symptoms. Six Self-Milieux were determined and named. Participants from privileged (aOR = 0.38) and self-sufficient (aOR = 0.37) milieux were less likely to seek help from a general practitioner than those from the entitled milieu. Participants from privileged (aOR = 0.30), collaborators (aOR = 0.50), disadvantaged (aOR = 0.33), and self-sufficient (aOR = 0.21) milieux were less likely to seek help from family members than those from the entitled and family-bound milieux. DISCUSSION: The study's strengths and limitations, as well as the cluster methodology, are discussed. The comparative results for the six Self-Milieux are interpreted based on current research. For example, participants from some milieux follow a help-seeking process proposed in previous research, while participants from other milieux seem to show a different process, one that ends in informal help-seeking.

Transition competence as an indicator of health outcomes related to transition.

BACKGROUND: Adolescents and young adults (AYAs) with chronic conditions face a transfer, defined as an actual shift from paediatric to adult-oriented health care. Transition competence as the self-perceived knowledge, skills and abilities regarding the transition process was considered extremely useful. AIM: This study was designed to investigate the impact of transition competence before and after the transfer on disease-specific quality of life (QoL) and health care satisfaction of AYAs with diabetes. RESULTS: In total, a sample of N = 90 AYAs with diabetes self-reported their transition competence, diabetes-specific QoL and satisfaction with care. Multiple linear regressions were used to analyse the impact of transition competence on satisfaction with care and QoL. Transition competence positively influenced the outcomes of satisfaction with care and QoL. CONCLUSION: Young adults with diabetes showed higher transition competence scores than adolescents with diabetes.

Development and Validation of the Questionnaire of Young People's Participation-Young Adults (QYPP-YA).

BACKGROUND: The Questionnaire of Young People's Participation (QYPP) was developed for use in children and adolescents. To track participation throughout transition from childhood to adulthood, we adapted it for young adults using focus groups. Aim of this study was to validate this measure, the QYPP-Young Adults (QYPP-YA). METHODS: We recruited young adults with cerebral palsy (CP) and a representative, same-aged sample of the general population (GP). The GP-sample was split into two equivalent subsamples, one part to identify the factor structure via exploratory factor analysis and another part to test the resulting model via confirmatory factor analysis. Reliability and different forms of validity were investigated. RESULTS: The final QYPP-YA includes 17 items assigned to six domains (Autonomy, Independency, Intimate Relationships, Interpersonal Relationships, Social Life, Online Communication). Scales show satisfying internal consistencies in the CP-sample and in the GP-sample, except for 'Online Communication'. Convergent, divergent and known-group validity were confirmed. CONCLUSIONS: The QYPP-YA instrument features promising psychometric characteristics to assess key domains of participation in healthy and disabled young adults. It provides a multidimensional, economic and sound assessment for use in population surveys and clinical trials.

Palmitoylation of the small GTPase Cdc42 by DHHC5 modulates spine formation and gene transcription.

The small GTPase Cdc42 exists in the form of two alternatively spliced variants that are modified by hydrophobic chains: the ubiquitously expressed Cdc42-prenyl and a brain-specific isoform that can be palmitoylated, Cdc42-palm. Our previous work demonstrated that Cdc42-palm can be palmitoylated at two cysteine residues, Cys188 and Cys189, while Cys188 can also be prenylated. We showed that palmitoylation of Cys188 is essential for the plasma membrane localization of Cdc42-palm and is critically involved in Cdc42-mediated regulation of gene transcription and neuronal morphology. However, the abundance and regulation of this modification was not investigated. In the present study, we found that only a minor fraction of Cdc42 undergoes monopalmitoylation in neuroblastoma cells and in hippocampal neurons. In addition, we identified DHHC5 as one of the major palmitoyl acyltransferases that could physically interact with Cdc42-palm. We demonstrate that overexpression of dominant negative DHHC5 mutant decreased palmitoylation and plasma membrane localization of Cdc42-palm. In addition, knockdown of DHHC5 significantly reduced Cdc42-palm palmitoylation, leading to a decrease of Cdc42-mediated gene transcription and spine formation in hippocampal neurons. We also found that the expression of DHHC5 in the brain is developmentally regulated. Taken together, these findings suggest that DHHC5-mediated palmitoylation of Cdc42 represents an important mechanism for the regulation of Cdc42 functions in hippocampus.

Measuring context that matters: validation of the modular Tele-QoL patient-reported outcome and experience measure.

PURPOSE: A setting-sensitive instrument for assessing Quality of Life (QoL) in Telemedicine (TM) was unavailable. To close this gap, a content-valid "add-on" measure was developed. In parallel, a brief index was derived featuring six items that summarise the main content of the multidimensional assessment. After pre- and pilot-testing, the psychometric performance of the final measures was investigated in an independent validation study. METHODS: The questionnaires were applied along with other standardised instruments of similar concepts as well as associated, yet disparate concepts for validation purposes. The sample consisted of patients with depression or heart failure, with or without TM (n = 200). Data analyses were aimed at calculating descriptive statistics and testing the psychometric performance on item, scale, and instrument level, including different types of validity and reliability. RESULTS: The proposed factor structure of the multidimensional Tele-QoL measure has been confirmed. Reliability coefficients for internal consistency, split-half, and test-retest reliability of the subscales and index reached sufficient values. The Tele-QoL subscales and the index demonstrated Rasch scalability. Validity of both instruments can be assumed. Evidence for discriminant construct validity was provided. Known-groups validity was indicated by respective score differences for various classes of disease severity. CONCLUSION: Both measures show convincing psychometric properties. The final multidimensional Tele-QoL assessment consists of six outcome scales and two impact scales assessing (un-)intended effects of TM on QoL. In addition, the Tele-QoL index provides a short alternative for outcome assessment. The Tele-QoL measures can be used as complementary modules to existing QoL instruments capturing healthcare-related aspects of QoL from the patients' perspective.

Mental health-related telemedicine interventions for pregnant women and new mothers: a systematic literature review.

BACKGROUND: Pregnancy and the postpartum period are times when women are at increased risk for depression and mental problems. This may also negatively affect the foetus. Thus, there is a need for interventions with low-threshold access and care. Telemedicine interventions are a promising approach to address these issues. This systematic literature review examined the efficacy of telemedicine interventions for pregnant women and/or new mothers to address mental health-related outcomes. The primary objective was to analyse whether telemedicine interventions can reduce mental health problems in pregnant women and new mothers. The secondary aim was to clarify the impact of type of interventions, their frequency and their targets. METHODS: Inclusion criteria: randomized controlled trials, with participants being pregnant women and/or new mothers (with infants up to twelve months), involving telemedicine interventions of any kind (e.g. websites, apps, chats, telephone), and addressing any mental health-related outcomes like depression, postnatal depression, anxiety, stress and others. Search terms were pregnant women, new mothers, telemedicine, RCT (randomised controlled trials), mental stress as well as numerous synonyms including medical subject headings. The literature search was conducted within the databases PubMed, Cochrane Library, Web of Science and PsycINFO. Screening, inclusion of records and data extraction were performed by two researchers according to the PRISMA guidelines, using the online tool CADIMA. RESULTS: Forty four articles were included. A majority (62%) reported significantly improved mental health-related outcomes for participants receiving telemedicine interventions compared to control. In particular (internet-delivered) Cognitive Behavioural Therapy was successful for depression and stress, and peer support improved outcomes for postnatal depression and anxiety. Interventions with preventive approaches and interventions aimed at symptom reduction were largely successful. For the most part there was no significant improvement in the symptoms of anxiety. CONCLUSION: Telemedicine interventions evaluated within RCTs were mostly successful. However, they need to be designed to specifically target a certain mental health issue because there is no one-size-fits-all approach. Further research should focus on which specific interventions are appropriate for which mental health outcomes in terms of intervention delivery modes, content, target approaches, etc. Further investigation is needed, in particular with regard to anxiety.

The Seeking Mental Health Care model: prediction of help-seeking for depressive symptoms by stigma and mental illness representations.

BACKGROUND: Only about half the people with depression seek professional health care services. To constitute the different predictors and associating variables of health care utilisation, we model the process and aim to test our hypothesised Seeking Mental Health Care Model. The model includes empirical influences on the help-seeking process to predict actual behaviour and incorporates superordinate (stigma, treatment experiences) as well as intermediate attitudinal variables (continuum and causal beliefs, depression literacy and self-efficacy). METHOD: All variables are examined in an online study (baseline, three- and six-month follow-up). The sample consisted of adults with depressive symptoms (PHQ-9 sum score ≥ 8), currently not receiving mental health care treatment. To examine the prediction of variables explaining help-seeking behaviour, a path model analysis was carried out (lavaan package, software R). RESULTS: Altogether, 1368 participants (Mage = 42.38, SDage = 15.22, 65.6% female) were included, 983 participating in at least one follow-up. Model fit was excellent (i.e., RMSEA = 0.059, CFI = 0.989), and the model confirmed most of the hypothesised predictions. Intermediary variables were significantly associated with stigma and experiences. Depression literacy (ß = .28), continuum beliefs (ß = .11) and openness to a balanced biopsychosocial causal model (ß = .21) significantly influenced self-identification (R2 = .35), which among the causal beliefs and self-efficacy influenced help-seeking intention (R2 = .10). Intention (ß = .40) prospectively predicted help-seeking behaviour (R2 = .16). CONCLUSION: The Seeking Mental Health Care Model provides an empirically validated conceptualisation of the help-seeking process of people with untreated depressive symptoms as a comprehensive approach considering internal influences. Implications and open questions are discussed, e.g., regarding differentiated assessment of self-efficacy, usefulness of continuum beliefs and causal beliefs in anti-stigma work, and replication of the model for other mental illnesses.

[Life events related to the German reunification and their associations with psychosocial health in a sample of northeast Germany]. / Nach-Wende-Ereignisse und deren Assoziation mit psychosozialer Gesundheit in einer nordostdeutschen Stichprobe.

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.

Under contract and in good health: a multigroup cross-lagged panel model of time use and health-related quality of life in working-age men and women.

BACKGROUND: Self-reported time-use in relation to health-related quality of life (HRQoL) has been widely studied, yet less is known about the directionality of the association and how it compares across genders when controlling for sociodemographic confounders. METHODS: This study focused on the working population of the most recent waves (2013-2018) of the Core-Study of the German Socio-Economic Panel (N = 30,518, 46.70% female, M = 39.24 years). It examined the relationship between three time-use categories (contracted, committed, & leisure time) and HRQoL (self-rated health & life satisfaction) in men and women via multigroup fixed effects cross-lagged panel models. The models controlled for sociodemographic background (age, household income, number of children living in household, employment status, education, & marital status), which was associated with time-use and psychosocial health in previous research. RESULTS: Contracted time showed consistent positive relationships with HRQoL across genders while associations with the other types of time use differed significantly between men and women and across indicators of HRQoL. CONCLUSIONS: The way we spend our time directly predicts our health perceptions, but in the same vein our health also predicts how we can spend our time. Contracted time in particular was associated with positive HRQoL, across genders, and beyond sociodemographic predictors, highlighting the important role of employment in health, for men and women alike. The impact of commitments beyond contracted time-use-like household chores and childcare-however, continues to affect mainly women, which ultimately reflects in poorer health outcomes.

Quality of life and mental health in emerging adults with cerebral palsy compared to the general population.

BACKGROUND: While evidence concerning Quality of Life (QoL) in youth with cerebral palsy (CP) in comparison to the general population has been accumulating, there is a lack of studies exploring differences on a wider range of positive and negative mental health outcomes in emerging adults. METHODS: This binational case control study is part of the SPARCLE cohort study on QoL and participation of youth with CP. QoL (WHOQOL-BREF), depression (PHQ-9), anxiety (GAD-7) and self-efficacy (GSE) were assessed in 198 emerging adults with CP and 593 emerging adults from the general population, matched for country of residence, age and gender. ANCOVAs with impairment and pain as covariates were run. RESULTS: Similar levels of QoL were found in both samples, except for the environmental domain, with better QoL for emerging adults with CP compared to the general population. There were significant descriptive differences regarding depression with worse levels in the CP sample, however, also worse levels of self-efficacy. Pain as a covariate had a significant negative impact on all measures, leading to poorer self-efficacy while worsening depression and anxiety; impairment had a significant worsening impact on physical QoL and self-efficacy only. CONCLUSION: Similar expressions of mental health outcomes in emerging adults with CP and the general population indicate the high adaptive capability of emerging adults with CP.

DHHC7-mediated palmitoylation of the accessory protein barttin critically regulates the functions of ClC-K chloride channels.

Barttin is the accessory subunit of the human ClC-K chloride channels, which are expressed in both the kidney and inner ear. Barttin promotes trafficking of the complex it forms with ClC-K to the plasma membrane and is involved in activating this channel. Barttin undergoes post-translational palmitoylation that is essential for its functions, but the enzyme(s) catalyzing this post-translational modification is unknown. Here, we identified zinc finger DHHC-type containing 7 (DHHC7) protein as an important barttin palmitoyl acyltransferase, whose depletion affected barttin palmitoylation and ClC-K-barttin channel activation. We investigated the functional role of barttin palmitoylation in vivo in Zdhhc7-/- mice. Although palmitoylation of barttin in kidneys of Zdhhc7-/- animals was significantly decreased, it did not pathologically alter kidney structure and functions under physiological conditions. However, when Zdhhc7-/- mice were fed a low-salt diet, they developed hyponatremia and mild metabolic alkalosis, symptoms characteristic of human Bartter syndrome (BS) type IV. Of note, we also observed decreased palmitoylation of the disease-causing R8L barttin variant associated with human BS type IV. Our results indicate that dysregulated DHHC7-mediated barttin palmitoylation appears to play an important role in chloride channel dysfunction in certain BS variants, suggesting that targeting DHHC7 activity may offer a potential therapeutic strategy for reducing hypertension.

Continuum beliefs and mental illness stigma: a systematic review and meta-analysis of correlation and intervention studies.

BACKGROUND: Promulgating a continuum model of mental health and mental illness has been proposed as a way to reduce stigma by decreasing notions of differentness. This systematic review and meta-analysis examines whether continuum beliefs are associated with lower stigma, and whether continuum interventions reduce stigma. METHODS: Following a pre-defined protocol (PROSPERO: CRD42019123606), we searched three electronic databases (PubMed, Web of Science, and PsycINFO) yielding 6726 studies. After screening, we included 33 studies covering continuum beliefs, mental illness, and stigma. Of these, 13 studies were included in meta-analysis. RESULTS: Continuum beliefs are consistently associated with lower stigma. Interventions were effective at manipulating continuum beliefs but differ in their effects on stigmatising attitudes. CONCLUSIONS: We discuss whether and to what extent attitudes towards people with mental illness can be improved by providing information on a mental health-mental illness continuum. It appeared to be relevant whether interventions promoted a feeling of 'us' and a process of identification with the person with mental illness. We discuss implications for the design of future interventions.

Characterization of CD177-reactive iso- and auto-antibodies.

BACKGROUND: CD177 is a surface protein on neutrophils and a main mediator for the surface expression of proteinase 3 (PR3). Its functions are largely unknown. At least three types of antibodies have been described to target CD177: isoantibodies, which are formed in CD177-null individuals as a result of an immune reaction following transfusion or pregnancy; autoantibodies present in sera from patients with autoimmune neutropenia; and antineutrophil cytoplasmic antibodies in sera from patients with glomerulonephritis with polyangiitis. In this study, we aimed to compare the binding characteristics of auto- and iso-antibodies to optimize their detectability in the neutrophil serology laboratory. STUDY DESIGN AND METHODS: The reactivity of iso- and auto-antibodies against CD177 was studied using granulocytes, "native" CD177/PR3 complex, and recombinant CD177 or PR3. RESULTS: All iso- and auto-antibodies were reactive with CD177/PR3 when immobilized with monoclonal antibody (moab) 7D8. Seventy-five percent of autoantibodies, but none of the isoantibodies, did not react with CD177/PR3 immobilized with moab MEM166. The majority of autoantibodies did not react with recombinant CD177, whereas most isoantibodies tested positive. DISCUSSION: Our results suggest that iso- and auto-antibodies against CD177 target different epitopes. Isoantibodies mainly target CD177 alone, while the majority of autoantibodies target a native epitope present on the neutrophil surface, but absent from recombinant CD177 which lacks PR3. Moab MEM166 binds to the native epitope and hinders the binding of CD177 autoantibodies. The results may help to design diagnostic strategies, especially for the identification of autoantibodies.

Determinants of participation and quality of life of young adults with cerebral palsy: longitudinal approach and comparison with the general population - SPARCLE 3 study protocol.

BACKGROUND: Effective inclusion in society for young people with disabilities is increasingly seen as generating opportunities for self-development, and improving well-being. However, significant barriers remain in the vast majority of activities meaningful for young adults. Research argues that various personal (disabilities, health) and environmental (access to the resources needed, accessible environment, discrimination, lack of personal economic independence) factors contribute to limited participation. However, previous studies conducted in young people with cerebral palsy (CP) mainly investigated the transition period to adulthood, and did not fully consider the whole range of impairment severity profiles or environmental barriers. In this study, we will use the follow-up of the SPARCLE cohort and a comparison group from the general population (1) to investigate the impact of the environment on participation and quality of life of young adults with CP, (2) to determine predictors of a successful young adulthood in educational, professional, health and social fields, (3) to compare quality of life and frequency of participation in social, work and recreational activities with the general population, (4) to document on participation and quality of life in those with severe disabilities. METHODS: The SPARCLE3 study has a combined longitudinal and cross-sectional design. Young adults with CP aged 22 to 27 years in 6 European regions previously enrolled in the SPARCLE cohort or newly recruited will be invited to self-complete a comprehensive set of questionnaires exploring participation (daily life and discretionary activities), health-related quality of life, body function, personal factors (health, personal resources), and contextual factors (availability of needed environmental items, family environment, services provision) during home visits supervised by trained researchers. Proxy-reports or adapted questionnaires will be used for those with the most severe impairments. The recruitment of a large group from the general population (online survey) will enable to identify life areas where the discrepancies between young people with CP and their able-bodied peers are the most significant. DISCUSSION: This study will help identify to what extent disabilities and barriers in environment negatively affect participation and quality of life, and how previous valued experiences during childhood or adolescence might modulate these effects.

Same same-but different: using qualitative studies to inform concept elicitation for quality of life assessment in telemedical care: a request for an extended working model.

BACKGROUND: Although telemedical applications are increasingly used in the area of both mental and physical illness, there is no quality of life (QoL) instrument that takes into account the specific context of the healthcare setting. Therefore, the aim of this study was to determine a concept of quality of life in telemedical care to inform the development of a setting-sensitive patient-reported outcome measure. METHODS: Overall, 63 semi-structured single interviews and 15 focus groups with 68 participants have been conducted to determine the impact of telemedical care on QoL. Participants were patients with chronic physical or mental illnesses, with or without telemedicine supported healthcare as well as telemedical professionals. Mayring's content analysis approach was used to encode the qualitative data using MAXQDA software. RESULTS: The majority of aspects that influence the QoL of patients dealing with chronic conditions or mental illnesses could be assigned to an established working model of QoL. However, some aspects that were considered important (e. g. perceived safety) were not covered by the pre-existing domains. For that reason, we re-conceptualized the working model of QoL and added a sixth domain, referred to as healthcare-related domain. CONCLUSION: Interviewing patients and healthcare professionals brought forth specific aspects of QoL evolving in telemedical contexts. These results reinforce the assumption that existing QoL measurements lack sensitivity to assess the intended outcomes of telemedical applications. We will address this deficiency by a telemedicine-related re-conceptualization of the assessment of QoL and the development of a suitable add-on instrument based on the resulting category system of this study.

How is the way we spend our time related to psychological wellbeing? A cross-sectional analysis of time-use patterns in the general population and their associations with wellbeing and life satisfaction.

BACKGROUND: Time-use surveys can closely monitor daily activities, times of stress and relaxation, and examine predictors and trajectories with regard to health. However, previous studies have often neglected the complex interaction of daily activities when looking at health outcomes. METHODS: Using latent profile analysis, this study examined patterns of self-reported daily time use (0-12h hours) for nine types of behaviour (work, errands, housework, childcare, care of persons in need, education, repairs and gardening, physical activity, and hobbies/leisure-time activities) in the 2018 wave of the German Socio-Economic Panel (N = 30,152; 51.9% female; M = 46.87 years). Sociodemographic variables, affective wellbeing, general and domain-specific life satisfaction, and self-rated health were inspected as predictors via multinomial logistic regression models. RESULTS: Six latent profiles emerged: full-time work (47.2%), leisure (33.8%), childcare (8.9%), education (7.0%), part-time work & care (2.6%), and care (0.5%). Overall, the care and part-time work & care profiles showed the lowest wellbeing scores, lower subjective health, and life satisfaction. Women were more likely to be members of the care and childcare profiles. Men were more likely to belong to the full-time work profile, and they reported significantly higher wellbeing than women. CONCLUSIONS: The analysis revealed distinct patterns of time use and a burden on women, given their investment in care and childcare. Part-time work, and care seemed particularly demanding, and thus, are important areas for prevention, for instance, regarding mental health problems. However, time use was assessed via self-reports, therefore future studies could implement objective measures like digital trackers to validate findings.

How can the utilisation of help for mental disorders be improved? A quasi-experimental online study on the changeability of stigmatising attitudes and intermediate variables in the process of utilisation.

BACKGROUND: Epidemiological studies show that even in highly developed countries many people with depression do not seek help for their mental health issues, despite promising prevention approaches encouraging people to seek help and reduce self-stigma. Therefore, an anti-stigma intervention study to support help-seeking behaviour will be developed on the basis of the newly explicated "Seeking Mental Health Care Model". METHODS: A quasi-experimental online study will be carried out to assess the effect of different intervention variables relevant for the help-seeking process. The study is conceived as a fractional factorial design. Participants will be screened for depressive complaints (PHQ-9 sum score ≥ 8) and current psychiatric/psychotherapeutic treatment. After baseline assessment the participants will be randomly allocated into one of the 24 study groups receiving different combinations of the vignette-based intervention aiming to reduce stigma and support help-seeking. Next, relevant outcome measures will be administered a second time. In a 3- and 6-month follow-up help-seeking behaviour will be measured. Gamified elements and avatar-choice techniques will be used to heighten study immersion and adherence. DISCUSSION: On the basis of the project results, promising research and intervention perspectives can be developed. Results, firstly, allow for a more detailed empirical investigation and conceptualisation of the stages of mental health care utilisation, as well as an examination of theoretical approaches to stigmatisation. Secondly, our online study could provide insights for an evidence-based design and evaluation of online interventions for people with a mental illness.

The interplay of gender, social context, and long-term unemployment effects on subjective health trajectories.

BACKGROUND: While a strong negative impact of unemployment on health has been established, the present research examined the lesser studied interplay of gender, social context and job loss on health trajectories. METHODS: Data from the German Socio-Economic Panel was used, which provided a representative sample of 6838 participants. Using latent growth modelling the effects of gender, social context (East vs. West Germans), unemployment (none, short-term or long-term), and their interactions were examined on health (single item measures of self-rated health and life satisfaction respectively). RESULTS: Social context in general significantly predicted the trajectories of self-rated health and life satisfaction. Most notably, data analysis revealed that West German women reported significantly lower baseline values of self-rated health following unemployment and did not recover to the levels of their East German counterparts. Only long-term, not short-term unemployment was related to lower baseline values of self-rated health, whereas, in relation to baseline values of life satisfaction, both types of unemployment had a similar negative effect. CONCLUSIONS: In an economic crisis, individuals who already carry a higher burden, and not only those most directly affected economically, may show the greatest health effects.
