The scope of research about kinship care has expanded. One area of interest is the impact social support has on kinship caregivers (Kelley, Whitley, & Campos, 2011). The Family Support Scale (FSS) has been used to measure social support among kinship caregivers (Kelley et al., 2011; Leder et al., 2007); however, there has been no rigorous examination of the psychometric properties of the FSS when administered to kinship caregivers. This study used a sample of 255 kinship caregivers to conduct a principal component analysis and developed a four-component structure for the FSS. The results suggest that the four-component structure identifies four sub-scales that have adequate face validity and internal consistency validity with this population.
