Parental styles and socialization trajectories are issues whose construction is mediated by parental beliefs and therefore by culture, so it s considerably relevant that they be investigated according to the context in which they are inserted. In order to identify parental styles and socialization trajectories of different family types, 40 parents resident in Rio de Janeiro with children between 7 and 11 years old participated in the study. They belonged to three family settings: 10 couples of nuclear families, 10 single mothers of parent families and 5 couples of remarried families. A sociodemographic questionnaire was used to collect data such as age, gender and family type. The Inventory of socialization/development goals (KELLER et al., 2006; adapted by SEIDL-DE-MOURA et al., 2008) was used to identify the socialization trajectories, the five images of parental care systems proposed by Keller (2005) were used for evaluation of parental systems and a semi-structured interview to identify parental styles. About the socialization trajectories, results pointed out that nuclear families tended to autonomous relational trajectory, whereas single patents and remarried families tended for relational trajectory. Regarding the parental styles, single parents and remarried families presented indications of indulgent style, with high respondingness and low demandingness. However, nuclear families demonstrated an authoritative style, valuing both dimensions equally. To this extent, the present study aims to contribute to the developmental psychology from a sociocultural perspective and to open ways for future investigations.
