Abstract
Responses for 2,012 Grandparent Strengths and Needs Inventories (GSNI) by grandparents, parents, and grandchildren were factor analyzed to determine if the underlying structure of the instrument fit the hypothesized dimensions suggested by the position of 60 items on six subscales. Two extraction methods, principal components and principal factors analyses, produced 10 factors with prerotation eigenvalues greater than 1.0. A principal component solution set at six factors yielded the "best fit," accounting for 49.2% of the variance. The pattern of item-to-factor correlation suggested that the 60 items tended to fit the hypothesized pattern of subscales. Empirical evidence supported the presence of six dimensions: (a) satisfaction, (b) success, (c) teaching, (d) difficulty, (e) frustration, and (f) information needs as constructs comprising the six subscales of the GSNI.
