    Abstract In recent years, the concept of quality of life (QoL) has gained significant importance within health care and clinical research, e.g., as in patient-reported outcomes. In gestational diabetes mellitus (GDM) care, enhancing QoL through reasonable interventions is considered equally important as achieving metabolic control and preventing complications in the treatment process, leading to the suggestion that QoL assessment should be implemented as a clinical standard in GDM care. Although a considerable number of questionnaires for the measurement of general as well as health-related and diabetes-specific QoL are frequently used in GDM research, a validated QoL questionnaire tailored to women with GDM does not exist in German-speaking countries. To develop and test such an instrument, we plan to conduct the following steps: (a) translate the Persian questionnaire GDMQ-36, the only GDM-specific questionnaire to date; (b) conduct expert ratings as well as pretests featuring cognitive debriefings and structured interviews with women suffering from GDM for evaluating comprehensibility, face and content validity; (c) pilot and validate the preliminary questionnaire in terms of testing its psychometric performance (e.g., via confirmatory factor analysis). The resulting GDM-specific questionnaire will facilitate a broader perspective of the pregnant women's expectations, needs, impairments, and burdens related to their disease, and its treatment. This enables physicians and other health professionals to establish an individualized treatment plan and to provide customized information, support, and psychological counseling, which helps to optimize the provided care.

    Abstract 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.

    Abstract Background: Only approximately a third of people with depressive symptoms seek professional health care. Furthermore, people labelled as mentally ill may experience stigmatisation, which can impede help-seeking behaviour.
    Aim: To examine the effects of three vignette-based interventions endorsing biopsychosocial causal beliefs and strengthening self-efficacy on help-seeking intention and behaviour, as well as the predictive values of these variables and previous treatment experience.
    Method: A quasi-experimental online study utilising a fractioned factorial design was carried out. People were screened for depressive symptoms and their current treatment status. After baseline assessment, they were randomly allocated into one of 24 groups receiving a combination of interventional messages. Actual help-seeking behaviour was measured at follow-ups 3 and 6 months after baseline.
    Results: Altogether,
    Conclusion: Biopsychosocial causal beliefs and self-efficacy have a direct effect on help-seeking intention. Interventions should include information on how to actually seek help as a means to strengthen self-efficacy beliefs and simulate previous treatment experience. Further research is needed to investigate the respective interaction effects on intention and behaviour.

    Abstract Background: To combat the global COVID-19 pandemic, contact tracing apps have been discussed as digital health solutions to track infection chains and provide appropriate information. However, observational studies point to low acceptance in most countries, and few studies have yet examined theory-based predictors of app use in the general population to guide health communication efforts.
    Objective: This study utilizes established health behavior change and technology acceptance models to predict adoption intentions and frequency of current app use.
    Methods: We conducted a cross-sectional online survey between May and July 2020 in a German convenience sample (N=349; mean age 35.62 years; n=226, 65.3% female). To inspect the incremental validity of model constructs as well as additional variables (privacy concerns, personalization), hierarchical regression models were applied, controlling for covariates.
    Results: The theory of planned behavior and the unified theory of acceptance and use of technology predicted adoption intentions (R
    Conclusions: This study identified several theory-based predictors of contact tracing app use. However, few constructs, such as social norms, have a consistent positive effect across models and outcomes. Further research is required to replicate these observations, and to examine the interconnectedness of these constructs and their impact throughout the pandemic. Nevertheless, the findings suggest that promulgating affirmative social norms and positive emotional effects of app use, as well as addressing health concerns, might be promising strategies to foster adoption intentions and app use in the general population.

    Abstract 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 (M
    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.

    Abstract Background: Despite available professional healthcare, people often delay or avoid help-seeking. Understanding the underlying reasons is crucial and research has explored the role of self-efficacy in this context. Additionally, studies have highlighted the significance of culturally influenced self-construals in individuals' health behaviour. There seems to be a relationship between self-efficacy and self-construal. The aim of the study is to explore the influence of self-efficacy on help-seeking, considering self-construal as a moderator. Differential experiences of self-efficacy and varying associations among help-seeking variables based on self-construal are posited.
    Methods: A quasi-experimental online study is conducted with a baseline assessment, including self-efficacy interventions, and follow-ups at three and six months. Self-construal groups are compared, i.e., independent vs. interdependent individuals. A series of multi-group path analyses are conducted to examine potential variations in the interventional effects and among the help-seeking variables respective of help-seeking instance, i.e. professional mental health care or informal care. Self-construal functions as the global moderator.
    Results: The study included N = 1'368 participants, 65.6 % identifying as female and an average age of 42.38 (SD = 15.22). More independent compared to more interdependent individuals were older, more frequently identified as male, had higher socioeconomic status, fewer depressive symptoms, and greater self-efficacy. Multi-group path analyses for professional mental health care (CFI = 0.992, RMSEA = 0.018, SRMR = 0.004) and informal help (CFI = 0.999, RMSEA = 0.004, SRMR = 0.006) demonstrated excellent model fits. The analysis for informal help was interpretable, as the unconstrained model had a significantly better fit than the constrained model. There were varying associations among help-seeking variables based on self-construals. The intervention effect was differential, with independent participants benefiting significantly (β = 0.203), while the effect was non-significant for interdependent participants.
    Discussion: The study's findings, strengths, and limitations are discussed in relation to current research. Results indicate differential experiences of self-efficacy interventions based on individuals' self-construal. Moreover, varying associations among help-seeking variables suggest self-construal-based differences in their interrelationships. These findings highlight the importance of considering self-construal in health related research.

    Abstract It is crucial to provide updated knowledge about blood (non-)donors, as it is necessary to design targeted interventions with the aim of retaining blood donors and thus contributing to a functioning health system. This study investigates the prevalence and socio-demographic patterning of lifetime blood donation, assessing blood donation intention within the next 12 months and exploring personal motives and deterrents of blood donation qualitatively in the German population. A face-to-face cross-sectional survey with 2531 respondents was conducted, representative of the German population in terms of age, gender, and residency. Closed as well as open questions were asked. Qualitative content analysis was used for coding the qualitative material. Basic descriptive statistics were conducted to address our research questions. More than one-third of the participants reported that they have donated blood at least once in their lifetime. Motives and deterrents were assigned to 10 domains with 50 main categories and 65 sub-categories. The most frequently stated motives for blood donation were "altruism", "social responsibility", and "charity", whereas the most frequently stated deterrents were "health status", "age", and "lack of time". This study provides information to tailor recruitment and reactivation strategies to address donors at different career steps-from non-donor to loyal donor.
