The main area of interest in this contribution is parental financial socialization, which includes the following two types of socialization: parental role-modelling and parental teaching. Of particular interest here is the tendency to repeat parents' patterns, in which the financial attitudes and behaviors imitate those of parents/guardians. The purpose of this paper is to identify the factors determining the adoption of saving attitudes by children, where it is identical to the attitudes of their parents/guardians - i.e. adoption of the propensity to save by children raised by parents/guardians with the same propensity. Based on the review of previous studies, the following research hypothesis was formulated: parental role-modelling and parental teaching determine the children’s tendency to repeat parents' saving patterns. The following research methods were used to verify the hypothesis: CART algorithm, review and critical analysis of the subject literature and the descriptive method.
