Editorial: Better Together: A Joined-Up Psychological Approach to Health, Well-Being, and Rehabilitation

It is exactly 30 years since Arthur Kleinman introduced the term " sociosomatic " in an attempt to refocus attention in the health and psychological sciences on the often apparent, yet all too frequently neglected, social aspects of illness, disorder, and well-being (Kleinman, 1986). Social and cultural causes, social mediators, and moderators, and social outcomes were suggested by Kleinman as representing an additionally helpful, legitimate, and clinically useful formulation of disorder and well-being. This framework contextualized such multifaceted intra-and inter-personal challenges within the social, cultural, and material contexts of peoples' everyday lives. Accordingly, the study of disorder and well-being necessarily requires the interdigitation of the person, their body, and their social and cultural world as essential and interdependent components of a comprehensive system of experience. Since Kleinman's call to arms, one might be forgiven for perceiving psychology to have become increasingly fractionated and divided from its common or shared base. Certainly, it can be observed that professional psychology has developed into increasingly specialized and more numerous " Divisions, " further " dividing " or separating relevant and complementary knowledge bases that are likely to have increasing relevance in furthering our understanding of significant social issues. The need for such conceptual and applied integration across specialisms remains compelling, particularly in the case of health and well-being—which is the principal focus of this Frontiers Research Topic. In the initial call for papers for this Research Topic, we stated that health and well-being are best understood in terms of a combination of biological, psychological, and social factors; yet most formulations in this area remain constructed at the individual level. Indeed, it is over 10 years since Suls and Rothman observed that of all the published articles in the American Psychological Association's journal Health Psychology, 94% assessed psychological variables only, with minimal attention given to broader socio cultural factors (Suls and Rothman, 2004). Thus, while the biopsychosocial model is the basic explanatory approach for understanding the whole person in health and illness, the social side of the approach remains underspecified and poorly integrated. Therefore, our principal aim as editors of this Research Topic was to encourage contributions that would permit readers to examine how social integration, social groups, social identity, and
