This article describes two researches on relation between parenting and the degree of satisfaction of the basic psychological needs postulated by Self Determination Theory: relatedness, autonomy, competence, standards internalization level and strength of volition. The results of study 1 confirmed that positive, affectionate, and autonomy-promoting relations with parents have positive effect on the degree of satisfaction of the basic psychological needs. Unduly severe demands and inconsistency both have negative effect on this satisfaction. The patterns of results concerning relation between parenting and the degree of satisfaction of the basic psychological needs differed between male and female participants. The data obtained in study 1 also indicate that positive parenting (positive, affectionate, and autonomy-promoting) causes internalization of standards pertain to school activity, and that negative parenting (unduly severe demands and inconsistency) is harmful for this internalization. This conclusion is also confirmed by the results of study 2 with regard to “personal strivings”. Additionally, study 2 proves that acceptance – displaying, and autonomy-promoting parenting both have a positive effect on strength of volition and that inconsistency and severe demands have adverse impact on volition..
