Due to increasing digitalisation, today’s working world is changing rapidly and provides managers with new challenges. Digital leadership is an important factor in managing these challenges and has become a key concept in the discussion about what kinds of skills managers need for digital transformation. The main research question our study explored was if digital leadership is associated with psychological well-being in upper-level managers. Based on a qualitative pilot study and relevant literature, we developed a new scale for digital leadership in managers. We conducted an online survey with a sample of 368 upper-level managers from a large German ICT-company. Using a stepwise logistic regression analysis, potential effects of digital leadership on psychological well-being (WHO-5) were analysed. Logistic regression analyses showed that better skills in digital leadership were significantly associated with higher well-being. Results also showed that gender, age and managerial experience had no effect in our model. Our study provides a valuable insight into the association between digital leadership and well-being in managers. However, further research is necessary to validate the newly developed scale for digital leadership and to confirm a causal effect in the relationship between digital leadership and well-being.

Background: There is a significant number of long-term breast cancer survivors in Germany. However, research on the psychological challenges of cancer survivors is limited. This analysis describes prevalence, development and determinants of depression and anxiety 5 to 6 years after diagnosis and identifies predictors for an increase of anxiety and depression over time. Methods: Data from 164 women was collected by survey and tumour documentation during post-operative hospital stay, 40 weeks and 5 to 6 years after diagnosis. Anxiety and depression were measured by the Hospital Anxiety and Depression Scale. Sankey-diagrams were created for visual presentation of prevalence over time. Logistic and linear regression models were calculated to identify determinants of anxiety and depression. Results: Respondents had higher levels of depression and anxiety 5 to 6 years than 40 weeks after the diagnosis. Lower vocational status and having children were associated with depression, surgery type was correlated with anxiety, and age, as well as comorbidities, were predictors for both anxiety and depression 5 to 6 years after diagnosis. An increase of depression over time was more likely when having children and comorbidities. An increase in anxiety was less likely after cancer recurrence. Conclusions: Findings highlight that anxiety and depression are relevant burdens for breast cancer survivors in Germany. Several sociodemographic and clinical predictors are identified. There is need for psychosocial support after acute treatment and in the long-term. Research on psychological burdens of long-term breast cancer survivors in the identified vulnerable groups is needed.

While research on individual health literacy is steadily increasing, less attention has been paid to the context of care that may help to increase the patient’s ability to navigate health care or to compensate for their limited health literacy. In 2012, Brach et al. introduced the concept of health literate health care organizations (HLHOs) to describe the organizational context of care. This paper presents our effort in developing and validating an HLHO instrument. Ten items were developed to represent the ten attributes of HLHO (HLHO-10) based on a literature review, an expert workshop, a focus group discussion, and qualitative interviews. The instrument was applied in a key informant survey in 51 German hospitals as part of a larger study on patient information and training needs (PIAT-study). Item properties were analyzed and a confirmatory factor analysis (CFA) was conducted to test the instrument’s unidimensionality. To investigate the instrument’s predictive validity, a multilevel analysis was performed that used the HLHO-10 score to predict the adequacy of information provided to 1,224 newly-diagnosed breast cancer patients treated at the sample hospitals. Cronbach’s α of the resulting scale was 0.89. CFA verified the one-factor structure after allowing for the correlation for four pairs of error terms. In the multilevel model, HLHO-10 significantly predicted the adequacy of information as perceived by patients. The instrument has satisfactory reliability and validity. It provides a useful tool to assess the degree to which health care organizations help patients to navigate, understand, and use information and services. Further validation should include participant observation in health care organizations and a sample that is not limited to breast cancer care.
