There is growing recognition that social isolation and a lack of connectedness with social groups is one of the reasons why the subjective well-being of homeless individuals is generally worse than the rest of the population. Past research amongst a range of populations suggests that the ability of an individual to take on new group memberships and/or their ability to maintain their memberships in meaningful groups is an important predictor of well-being. In a mixed method study (N = 119), we examined the extent to which experiences at homeless accommodation form building blocks for the formation of multiple group memberships and to what extent this predicts positive well-being. Qualitative analysis reveals the importance of feeling connected to the homeless service and supported by homeless accommodation staff. Linking these data to quantitative data from a second wave, we found that these experiences predicted well-being. These findings provide further support for a strength-based approach to homelessness, by providing insights into the ways that experiences at homeless accommodation can contribute to the development of multiple group memberships (i.e. social capital), and enhance the well-being of those experiencing, and exiting, homelessness.

Those experiencing homelessness demonstrate lower levels of well-being and poorer mental health than the general population, and may be at great risk of losing social connections at the point of becoming homeless (Biswas-Diener & Diener, 2006;Fischer, Shapiro, Breakey, Anthony, & Kramer, 1986). Research has consistently demonstrated that poverty, substance abuse, poor mental health, and past instances of trauma or abuse constitute significant risk factors or pathways into homelessness (Fitzpatrick, Bramley, & Johnsen, 2013;Shelton, Taylor, Bonner, & van den Bree, 2009). Notwithstanding the importance of this research, the focus on risk factors and problems has also led to neglect of the strengths and resources of people who are homeless. This is unfortunate because an empirically based understanding of such strengths and resources is important to shed light on opportunities for effective interventions (Biswas-Diener & Diener, 2006). Consistent with this recognition, recently, the focus has moved towards understanding pathways out of homelessness and prioritizing the well-being of those who have experienced homelessness (Clapham, 2010;Mayock, O'Sullivan, & Corr, 2011). In particular, Biswas-Diener and Diener (2006) found that good social relationships amongst homeless individuals contribute to well-being, averting some of the negative effects of being homeless. This finding is also consistent with a mounting body of evidence showing that effective social support through social connectedness may enhance health and wellbeing (Cohen & Wills, 1985;Jetten, Haslam, Haslam, Dingle, & Jones,...
