The article reaches the problem concerning lack of models in preparing parents for an affirmative behavior, generally; and the influence of parental attitudes and non-affirmative behavior manifestations towards the development of non-affirmative behavior of their children, especially. The research captured 127 children and 127 parents for the purpose of determining the impact of parents' behavioural model (social courage, initiation in social contacts and selfconfidence) on the formation and development of self-confidence at children aged 7 - 16 years old. The results of the research show evidence that there is a correlations between parents lack of trust, lack of social courage; and children’s behavior manifestations such as anxiety, difficulties of self representation, frustration in goal achievement, fear of knowledge evaluation situations, and fear of not corresponding to the awaiting of the environment. The received results are to be used in the aims of elaboration of some educational programs concerning development of affirmative behavior at parents as at their children.
