This study measured marital satisfaction of low-income couples in a Western state following participation in the Building Healthy Marriages program, which aimed to educate couples and increase relationship satisfaction. The researchers' goals were the following: To determine the areas in which participants experienced the greatest number of problems before entering the program, to assess the program's impact on marital satisfaction, and to examine the differences in program impact between various demographic groups. To assess the program's impact, participants were administered the Marital Satisfaction Inventory-Revised before beginning the program and 1 year after completing the pretest. Before starting the program, couples experienced the greatest number of challenges in relationships within their families of origin and problem-solving communication and the fewest problems in areas related to their children. Couples reported significant improvements in marital satisfaction. These changes did not differ significantly between different gender and ethnicity groups. (Contains 2 tables.)
