An educational program for grandparents that aims to help women and men who aspire to be better grandparents has proven effective. The curriculum of the program consists of 12 weekly classes that emphasize the perspectives and experiences of each of the three generations and encourages the grandparents to become more influential in their grandchildren's lives. Strom, Collinsworth, Strom, Griswold et al. (1992) conducted an experimental study with 400 predominantly African-American grandparent participants. Results revealed that the 200 grandparents randomly assigned to the training program scored significantly higher on the Grandparent Strengths and Needs Inventory (GSNI) than the 200 grandparents in the control group. The GSNI is a scale developed to measure and rate one's grandparenting style. Additionally, the results of an earlier experimental study conducted by Collinsworth, Strom, Strom and Young (1991) were similar. The 210 grandparents who participated in the program scored significantly higher on the GSNI when compared to the scores of the 185 grandparents from the control group.
