Sexual offences lead to significant and protracted consequences suffered by victims, often are connected to different rape myths, as well as a high rate of non-reporting to the police. Therefore, the purpose of the present study was to examine the level of attributed guilt to the damaged party and to the defendant, the causes of the defendant’s behaviour and the assessment of adequate sanctioning of the juvenile defendant for the sexual offence, depending on the type of the offence and the characteristics of the damaged party. Also, the purpose was to examine the contribution of socio-demographic characteristics and public attitudes about rape, victims of rape, treatment of sexual offenders and the causes of their behaviour to the attribution of guilt to the damaged party and the defendant, as well as to the sanctioning of the juvenile defendant for the sexual offence. This study was carried out using an online questionnaire on a convenience sample of 360 participant over the age of 18 (73.3% women). Vignettes with descriptions of the sexual offence were used in the study, as well as the following instruments: Illinois Rape Acceptancy Scale Short Form (Payne, Lonsway i Fitzgerald, 1999), Attitudes Towards the Treatment of Sex Offenders(Wnuck, Chapman i Jeglic, 2006) and the adapted form of Attribution od Blame Scale (Bieneck i Krahé, 2011), and the following measures: victim credibility, attribution of causes of the defendant’s behaviour and sanctioning of the defendant. Results of the study indicated that the participants who were presented with a description of attempted rape were significantly more prone to rehabilitation and shorter prison sentencing and they considered mediation a more adequate form of sanction for the defendant, compared to the participants who were presented with a description of rape. Participants holding negative attitudes toward sexual offenders and their treatment attributed more guilt to the defendant, were more prone to recommend a prison sentence for the defendant, the proposed length of the prison sentence was longer, selected sanctions of control and punishment of the defendant more often and assessed mediation as a less adequate sanction. The sex of the participant retained a significant independent contribution and the results indicated that women recommended shorter prison sentencing, selected sanctions of rehabilitation more often, and sanctions of control and punishment of the juvenile defendant for the sexual offence less often.
