Using Street Participatory Action Research (Street PAR), we examined the role of subjective neighborhood quality in bypassing adolescence (through adultification) and pro-violence attitudes among Black male youth. One hundred and thirty-seven street-identified, Black adolescent males (M/SD age = 18.07/1.66) were recruited using snowball sampling through social networks of individuals who identified as “street” or engaged in illegal activity. Respondents reported on neighborhood quality, bypassing adolescence, and pro-violence attitudes. Results showed that poorer perceived neighborhood quality correlated positively with bypassing adolescence and pro-violence attitudes. Bypassing adolescence mediated the association between neighborhood quality and pro-violence attitudes. Thus, street-identified Black boys who had more negative perceptions of their neighborhoods endorsed more positive attitudes toward violence and greater bypassing adolescence, or perceived adultification through street life. This novel finding contextualizes the development of violence attitudes in this understudied population and may suggest that bypassing adolescence is an important site of resilience within a street-identified Black masculinity framework.
