The purpose of this study was to examine to the differences of family leisure motivation and family leisure constraints between German families and Korean families, and analyze the relationship among family leisure motivation, family leisure constraints, and family strengths. The sample in this study consisted of 102 Korean two-parent families with teenagers and 147 German two-parents families with teenagers. The results were as follows: 1) family bonding motivation and rest motivation did not differ significantly between German families and Korean families while educational motivation and obligatory motivation differ significantly between the two. 2) While Korean families were more constrained to intrapersonal constraints, German families were more constrained to interpersonal constraints. 3) Educational motivation, family bonding motivation, rest motivation, interpersonal constraints, and structural constraints were found to be significantly correlated with German family strength while educational motivation, family bonding motivation, rest motivation, and interpersonal constraints were found to be significantly correlated with Korean family strength.
