Social support’s impact upon health and well-being has been well studied, with a range of conceptualizations put forward as to how social support operates. Overall, the literature suggests that social support influences health and well-being both positively and negatively, in both direct and indirect ways. What is lacking in much of this work, though, is a more complete understanding of what influences the development, use, and experience of social support, and how such a conceptualization relates to health and well-being. The purpose of this study was to therefore undertake an exploration of such a multidimensional conceptualization of social support by examining if and how adult attachment style is related to social support, how this relates to psychosocial functioning and well-being; and in doing so develop a measure that captures this more nuanced view of social support. Drawing on earlier work undertaken by Henderson and his colleagues (1980), a questionnaire version of their clinical interview was developed and its psychometric properties established. As such, the measure developed, the Interview of Social Interaction – Questionnaire version (ISSI-Q), examines support from attachment-based and diffuse supportive relationships concurrently. Psychometrically, the findings from the current study suggest that the ISSI-Q is a reliable and valid measure, and that it meaningfully aligns with theory and previous research.
