Methods: Participants were 1361 12-17 year old adolescents (M=16.4, SD=0.9) in three different groups, juvenile delinquents (N=344), and school students (N=1017, 35% boys) from a city in Northwestern part of Russia with population of 360.000.
Results: Juvenile delinquents reported higher levels of both witnessing (D=1.97 (1.78) vs B=1.21 (1.44) vs G=.83 (1.16); F=74.30, p>.001) and victimization (D=1.39 (1.39) vs B=.50 (.83) vs G=.31 (.65); F=74.30, p>.001). As for differences in problem scores according to the degree of severity of violence exposure, direct victimization was associated with reporting significantly higher levels of depression, anxiety, somatization, alcohol use, binge drinking and aggressive beliefs among adolescents from all three study groups. The main effect for the degree of exposure to violence for the total group was significant (Wilks’ lambda=.918; F (14, 2690) = 8.42, p<.000, η2 = .042), with increasing problems scores by increasing exposure to community violence. The main effect for group was also significant (Wilks’ lambda=.695; F (14, 2690) = 38.39, p<.000, η2 = .167), demonstrating differences between variables of interest between the study groups.
Considering that the differences by outcome, country and gender could have been masked by use of the MANCOVA analysis, each outcome was examine separately in order to determine whether the patterns that are reported from the MANCOVA hold up with each outcome individually. The results obtained have been largely similar.
Conclusions: Our findings that problems scores increased along with severity of violence exposure and generalizability of this pattern to all three groups expand previous research about a consistent relationship between community violence and psychopathology. Findings are of relevance both for identifying adolescents at risk for mental health problems as a result of exposure to community violence and for preventive efforts.
