Recently, environmental psychology research has focused on human-nature relationships; thereby the promising concept of connectedness with nature (CN) was investigated in detail. Empirical evidence suggests CN predicts conservation behaviour, psychological well-being, and leisure time preferences. Results from quantitative as well as qualitative studies show a preference for nature and natural settings, compared to built ones. We propose CN as important predictor in leisure time behavior and human health, currently not being considered in research as well as in practise according to its importance. The aim of this presentation is to show results from quantitative as well as qualitative studies on CN. All studies were carried out in Vienna, Austria and its surroundings. Participants were part of the general population aged between 16 and 84. First, we explored the relationship (N=547) between CN, different domains of well-being (WB) and time spent in nature for recreational purposes (TINrp). CN was assessed with two measures: the connectedness with nature scale and the connectedness with nature singleitem scale. Further, we applied a set of measures for WB and TINrp. CN was found to be related with psychological WB, vitality, the personality factor meaningfulness as well as transcendental aspects, even when controlling for effects of age and sex. TINrp correlated even higher with CN compared to WB and was less prone to confounding. Second, we investigated motives for being in nature, evaluations of environments and preferences for indoor or outdoor setting using a mixed quantitative and qualitative approach (N=130). Participants´ motives for being in nature differed significantly according to the participants´ level of CN. While these low on CN sojourned in nature for utilitarian or social reasons, participants high on CN sojourned in nature for rather restorative reasons. Outdoor settings were perceived as more restorative as the indoor settings. Moreover, they were preferred and evaluated as more positive. In summary, we identified CN as relevant for mental health and health related behaviour. As being outdoors is perceived and evaluated highly positive, being in nature contributes to individuals´ recreation and well-being, especially for those high on CN. CN should be considered in health education and health promotion, analogous to its account in the environmental domain. Further, we suggest introducing CN as a relevant moderating factor in restoration. So far, our findings are in line with prior research, provide new insights into underlying mechanisms and are subject of suggestions and recommendations. However, some open questions remain. “What are peoples´ inner images of nature? What do they associate and expect when being asked to think of nature?” These questions are topic of an ongoing qualitative study with participants (N= 80) from the general population.
