This study aimed at assessing gender and birth order influence on parenting and perceived parental favoritism from the children perspective. The participants were 322 adolescents aged between 13 and 17 years old. Two instruments were used to collect data - Parenting Styles Inventory and a questionnaire developed by the authors. Non-parametrical statistics (Mann-Whitney and Kruskal-Wallis) were used to analyze the obtained data. Results have shown that: (a) child gender has significant influence on the score of parenting styles; (b) firstborn girls present significantly higher risk of suffering negative parental practices and, (c) the perceived parental favoritism is significantly modulated by both gender and birth order.
