Background Dating violence (DV) is a public health problem that could have serious repercussions for the health and well-being of a large number of adolescents. Several neighborhood characteristics could influence these behaviors, but knowledge on such influences is still limited. This study aims at (1) evaluating the associations between neighborhood characteristics and DV, and (2) assessing how spatial scale influences the estimations of the latter associations. Methods The Québec Health Survey of High School Students (2016–2017) was used to describe DV. Neighborhoods were operationalized with polygon-based network buffers of varying sizes (ranging from 250 to 1000 m). Multiple data sources were used to describe neighborhood characteristics: crime rate, alcohol outlet density (on-premises and off-premises), walkability, greenness, green spaces density, and youth organizations density. Gendered-stratified logistic regressions were used for assessing the association between neighborhood characteristics and DV. Results For boys, off-premises alcohol outlet density (500 m) is associated with an increase in perpetrating psychological DV. Crime rate (500 m) is positively associated with physical or sexual DV perpetration, and crime rate (250 m) is positively associated with physical or sexual DV victimization. Greenness (1000 m) has a protective effect on psychological DV victimization. For girls, walkability (500 m to 1000 m) is associated with a decrease in perpetrating and experiencing psychological DV, and walkability (250 m) is negatively associated with physical or sexual DV victimization. Conclusions Several neighborhood characteristics are likely to influence DV, and their effects depend on the form of DV, gender, and spatial scale. Public policies should develop neighborhood-level interventions by improving neighborhood living conditions.

Many adolescents experience violence in the context of dating and romantic relationships. Neighborhoods can influence dating violence by offering certain resources which can provide social support and opportunities for social participation, but knowledge about these effects is still limited. The purpose of the current study was to (a) assess the association between neighborhood social support, social participation, and dating violence, and (b) explore possible gender difference in these associations. This study was conducted on a subsample of 511 participants living in Montréal from the Québec Health Survey of High School Students (QHSHSS 2016–2017). QHSHSS data were used to measure psychological and physical/sexual violence (perpetration and victimization), neighborhood social support, and social participation, as well as individual and family covariates. Several neighborhood-level data from multiple sources were also used as covariates. Logistic regressions were performed to estimate associations between neighborhood social support and social participation, and Dating violence (DV). Analyses were conducted separately for girls and boys to explore possible gender differences. Findings suggest that girls who reported high neighborhood social support had a lower risk of perpetrating psychological DV. High social participation was associated with a lower risk of perpetrating physical/sexual DV for girls, whereas it was associated with a higher risk of perpetrating psychological DV for boys. Preventive strategies to foster social support in neighborhoods, such as mentoring programs, and the development of community organizations to increase the social participation of adolescents could help reduce DV. To address the perpetration of DV by boys, prevention programs in community and sports organizations targeting male peer groups should also be developed to prevent these behaviors.
