Objective: To evaluate among stakeholders the support for the new, dynamic concept of health, as published in 2011: ‘Health as the ability to adapt and to self-manage’, and to elaborate perceived indicators of health in order to make the concept measurable.Design: A mixed methods study: a qualitative first step with interviews and focus groups, followed by a quantitative survey.Participants: Representatives of seven healthcare stakeholder domains, for example, healthcare providers, patients with a chronic condition and policymakers. The qualitative study involved 140 stakeholders; the survey 1938 participants.Results: The new concept was appreciated, as it addresses people as more than their illness and focuses on strengths rather than weaknesses. Caution is needed as the concept requires substantial personal input of which not everyone is capable. The qualitative study identified 556 health indicators, categorised into six dimensions:bodily functions, mental functions and perception, spiritual/existential dimension, quality of life, social and societal participation,anddaily functioning,with 32 underlying aspects. The quantitative study showed all stakeholder groups consideringbodily functionsto represent health, whereas for other dimensions there were significant differences between groups. Patients considered all six dimensions almost equally important, thus preferring a broad concept of health, whereas physicians assessed health more narrowly and biomedically. In the qualitative study, 78% of respondents considered their health indicators to represent the concept.Conclusions: To prevent confusion with health as ‘absence of disease’, we propose the use of the term ‘positive health’ for the broad perception of health with six dimensions, as preferred by patients. This broad perception deserves attention by healthcare providers as it may support shared decision-making in medical practice. For policymakers, the broad perception of ‘positive health’ is valuable as it bridges the gap between healthcare and the social domain, and by that it may demedicalise societal problems.

Objectives The My Positive Health (MPH) dialogue tool is increasingly adopted by healthcare professionals in the Netherlands as well as abroad to support people in their health. Given this trend, the need arises to measure effects of interventions on the Positive Health dimensions. However, the dialogue tool was not developed for this purpose. Therefore, this study aims to work towards a suitable measurement scale using the MPH dialogue tool as starting point. Design A cross-sectional study design. Participants and settings A total of 708 respondents, who were all members of the municipal health service panel in the eastern part of the Netherlands, completed the MPH dialogue tool. Methods The factor structure of the MPH dialogue tool was explored through exploratory factor analysis using maximum likelihood extraction. Next, the fit of the extracted factor structure was tested through confirmatory factor analysis. Reliability and discriminant validity of both a new model and the MPH scales were assessed through Cronbach’s alpha tests. Results Similar to the MPH dialogue tool, the extracted 17-item model has a six-factor structure but named differently, comprising the factors physical fitness, mental functions, future perspectives, contentment, social relations and health management. The reliability tests suggest good to very good reliability of the aimed measurement tool and MPH model (Cronbach’s alpha values ranging from, respectively, 0.820 to 0.920 and 0.882 to 0.933). The measurement model shows acceptable discriminant validity, whereas the MPH model suggests overlap between domains. Conclusion The results suggest that the current MPH dialogue tool seems reliable as a dialogue, but it is not suitable as a measurement scale. We therefore propose a 17-item model with improved, acceptable psychometric properties which can serve as a basis for further development of a measurement scale.

Background: A significant number of medical students suffer from burnout symptoms and reduced empathy. This controlled, quasi-experimental study aimed to investigate whether a mind–body medicine (MBM) skills course could reduce perceived stress and increase empathy and self-reflection in medical and nursing students. Methods: The MBM course (consisting of experiential sessions of mind–body techniques and group reflections) was piloted among Dutch medical students and Swedish nursing students. Main outcome variables were perceived stress (PSS), empathy (IRI subscales perspective taking, fantasy, empathic concern, and personal distress), and self-reflection (GRAS). Participating and control students completed questionnaires at baseline, post-intervention, at 6 and 12 months follow-up. Results: Seventy-four medical and 47 nursing students participated in the course. Participating medical students showed significantly increased empathic concern [1.42 (95% CI 0.05, 2.78), p = 0.042], increased fantasy [3.24 (95% CI 1.58, 4.90), p < 0.001], and decreased personal distress [−1.73 (95% CI −3.04, −0.35), p = 0.010] compared to controls until 12 months follow-up. Participating nursing students showed significantly decreased levels of perceived stress [−5.09 (95% CI −8.37, −1.82), p = 0.002] and decreased personal distress [−5.01 (95% CI −6.97, −3.06), p < 0.001] compared to controls until 12 months follow-up. Conclusions: This study demonstrated long-term beneficial effects of the MBM course on perceived stress and empathy in medical and nursing students.

Integrative Medicine (IM) is an emerging field in paediatrics, especially in the USA. The purpose of the present study was to assess the attitudes and beliefs of Youth Health Care (YHC) physicians in the Netherlands toward IM in paediatrics.
