Sexual violence is a major public health, societal, and judicial problem worldwide. Studies investigating the characteristics of its offenders often rely on samples of convicted offenders, which are then biased by low reporting and conviction rates of sexual offences. The reliability of self-report studies of undetected sexual offenders, however, is threatened by underreporting of sexually aggressive acts. Despite these limitations, we argue that it is important to publish available data on self-disclosed sexual aggression to learn more about those who are more likely to report own sexual aggression and to further improve self-report methods. Based on a self-report study conducted in a representative sample (n = 4,693) of the Belgian general population aged 16 to 69, we provide lifetime and past-year prevalence rates of sexual aggression and report the characteristics of the events, including type, target, and the applied coercion strategies. A logistic regression analysis revealed factors associated with self-disclosed sexual aggression. Almost 4% of all participants reported at least one incident of hands-on sexual aggression. Men were more likely than women to report sexual aggression (aOR: 5.33 (95% CI:3.62-7.86). Furthermore, a history of sexual victimization was associated with sexual aggression. In most cases, the target was an (ex)partner or friend. About 4 in 5 perpetrators indicated that none of the given coercion strategies (i.e., force, threat, verbal pressure, or exploiting the victim’s incapacitation or the own position of authority) applied to the incident. Further research is needed to clarify under which circumstances sexual aggression occurs and which factors increase reporting thereof.

Abstract Background and aims Previous studies on smartphone use motivation (SUM) and problematic smartphone use (PSU) have been limited in the utilization of regional samples of emerging adults (e.g., college students) and also in the foci on the direct association between SUM and PSU. To address such gaps, using data from a large, national representative sample of Chinese young adolescents and their parents this study examined the associations between adolescents' various types of SUM and their PSU, and also tested the potential mediating roles of smartphone use time (SUT) that adolescents spent on various activities in such associations. Methods A nationwide representative sample of 8,261 Chinese adolescents (Mage = 12.86 years old, SD = 1.76; 42.6% females) and their parents (49% mothers) participated in this survey study. Results Instrumental SUM (i.e., to expand knowledge or acquire information) was associated negatively with PSU via longer SUT spent on learning and shorter SUT spent on entertainment and communication. Self-expression SUM (i.e., to gain acceptance and recognition of others by maintaining or improving self-images) was associated with longer SUT spent on both learning and entertainment, which, in turn, predicted lower and higher levels of PSU, respectively. Last, hedonic SUM (i.e., to gain pleasure) was associated positively with PSU via longer SUT spent on entertainment and communication. Discussion These findings contribute to the literature by adding greater specificity in our understanding of the implications of SUM and SUT in the etiology of PSU during the critical life stage of adolescence in a Chinese cultural context.
