Measuring social support among kinship caregivers: validity and reliability of the Family Support Scale.

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.
