Background/Aim. Conduct disorder is characterized by repetitive and persistent presence of dissocial, aggressive and defiant behavioral patterns, thus represents important public issue with comprehensive and far-reaching consequences both for the individual and society. The aim of this study was to investigate the differences in sociodemographic family characteristics and the prominence of parental acceptance/rejection dimensions in groups of adolescents with and without conduct disorder, as well as to examine the connection between parental acceptance/rejection dimensions and externalizing symptoms in the group of adolescents with conduct disorder. Methods. This research was conducted on 134 adolescents, aged 15 to 18, using the Parental Acceptance/Rejection Questionnaire (PARQ child), Youth Self-Report (YSR), and a questionnaire constructed for the purpose of this survey. Results. The results showed that the number of adolescents with conduct disorder coming from divorced families was significantly higher than from complete families (44.8% vs 13.4%, respectively; p < 0.001). Also, in this group of adolescents there was a statistically significantly higher number of parents suffering from psychiatric disorders compared to the controls (31.3% vs 8.9%; respectively; p = 0.001). The perceived rejection dimension and the total index of maternal acceptance/ rejection were significantly higher in adolescents with conduct disorder than in those with no such disorder (132.30 ? 38.05 vs 93.91 ? 26.29 respectively; p < 0.001). Similar results were found for paternal acceptance/rejection dimension (129.40 ? 39.58 vs 86.10 ? 15.95 respectively; p < 0.001). Adolescents with conduct disorder and severe perceived maternal and paternal rejection showed a significantly higher average score on the subscale of externalizing symptoms (14.55 ? 4.45 and 13,27 ? 5,05) compared to adolescents with conduct disorder and lower total index of parental acceptance/rejection (8.32 ? 5.05 and 8.28 ? 5.08). Conclusion. The results suggest that adolescents with conduct disorder perceive their parents as more rejecting and less warm and supportive compared to adolescents without conduct disorder. The perception of significant and severe parental rejection was associated with a significantly higher averaged score on the subscale of externalizing symptoms in the group of adolescents with conduct disorder compared to those with no such disorder. It was found that adolescents with conduct disorder most often come from large families, have divorced parents or parents with multiple psychiatric disorders.
