This study was conducted to find an answer to the question of "Do social problem-solving skills of 5-6 years old children differentiate depending on the levels of maternal acceptance rejection?" The participants of the study included 359 5-6 years old children and their mothers. Wally Social Problem-Solving Test and PARQ (Parental Acceptance-Rejection Questionnaire) were used in the study. It was observed that the mean scores that the children got from Wally Social Problem-Solving Test for the social problem-solving skills differed at a statistically significant level according to the low, medium, and high rejection levels that mothers got from the PARQ. According to the scores obtained from "warmth/affection," "hostility/aggression," and "undifferentiated rejection" subscales of PARQ, social problem solving skill scores of the children in three groups, also differed in these three subscales depending on a rejection level of mothers. But it was determined that children's social problem-solving skill scores did not differentiate according to the scores obtained from "indifference/neglect" subscale. This result proves that the interaction between the children and the mothers that accept their children positively contributes to ability of the children's social problem-solving skills.
