A new measure of women's relationships, the Relational Health Indices (RHI), comprises three scales that assess growth-fostering connections with peers, mentors, and communities. The RHI was developed using the Relational Model (Jordan, Kaplan, Miller, Stiver, Surrey, 1991; Miller & Stiver, 1997), a theory of women's psychological development. The 37-item measure assesses three conceptual dimensions of growth-fostering relationships: engagement, authenticity, and empowerment/zest. This study examined the psychometric properties of the RHI with a group of 450 students at a women's liberal arts college, providing evidence for the reliability, validity, and utility of the new measure. The factor analyses confirmed a three-subscale structure: engagement, authenticity, empowerment/zest. The RHI's components generally demonstrate good overall internal consistency. Furthermore, associations between RHI scales and convergent validation scales were significant and in the direction hypothesized. Correlations with adjustment scales varied across the RHI components. The RHI has potential for enriching our understanding of important, subtle qualities and complex dynamics of both dyadic and group relationships, especially among women. The instrument is available for use by researchers interested in continuing the scale and theory development. The importance of social support and relationships in women's lives has been studied extensively (e.g.. Findings from such studies indicate that the quality and na-ture of women's relationships may be more meaningful than their quantity or structure (Bryant, 1985; Fiore, Becker, & Coppel, 1983; Waldrop & Halverson, 1975). In partic-ular, relationships that are intimate and mutual can facili-tate self-disclosure, emotional resiliency, coping strategies,, and student assistants, including Stefanie Wolf and Cinnamon Stetler, for their important contri-butions to our measurement conceptualization, development, and testing.
