Preventing youth violence perpetration among girls

Associations of Parental Monitoring and Violent Peers with Latino Youth Violence

This study aimed to examine the associations of parental monitoring and violent peers with violence among Latino youth, and whether these associations varied by acculturation. 133 adolescents were surveyed. Associations between parental monitoring, peer violence, and physical and non-physical violence were examined using bivariate and multivariable negative binomial regression. Multivariable analysis was stratified by age and acculturation. A path model examined whether peer violence mediated the relationship between parental monitoring and youth violence. Stratified analysis demonstrated that peer violence increased the risk of physical (RR = 1.24; 95% CI 1.02-1.20) and non-physical violence (RR = 1.32; 95% CI 1.08-1.62) for high-acculturated youth, whereas parental monitoring was protective for low-acculturated youth (physical RR = 0.88; 95% CI 0.78-0.99; non-physical RR = 0.80; 95% CI 0.68-0.93). In path analysis, low parental monitoring increased risk of involvement with violent peers, which was associated with increased risk of youth violence. Interventions may benefit from focusing on parental monitoring, peer violence, and tailoring by acculturation.

Relationships Between Mental Health, Skill Sets, and Violence Perpetration Among Adolescent Girls

This study examines relationships between emotional health, stress management skills, fight-avoidance skills, and two forms of violence perpetration among adolescent girls at high risk for violence involvement. Participants ( n = 253) were 13- to 17-year-old girls enrolled in a randomized controlled trial. The current study was completed with baseline data collected prior to the start of the intervention. Analyses examined self-report outcome measures of physical violence perpetration in the past 6 months (five-item scale, α = .79) and relational aggression perpetration in the past 30 days (six-item scale, α = .77). Independent variables included baseline measures of self-esteem (four-item scale, α = .89), emotional distress (six-item scale, α = .89), stress management skills (eight-item scale, α = .86), and fight avoidance skills (five-item scale, α = .70). Multivariate regression models predicted each form of violence perpetration controlling for age, race/ethnicity, violence victimization, and clustering of participants within clinics. Initial bivariate results showed that stress management skills and fight avoidance skills were inversely and significantly related to perpetration of both relational and physical violence. Emotional distress was related to significantly higher levels of both violence outcomes. In contrast, self-esteem was not significantly related to either violence outcome. Multivariate analyses revealed that stress management skills and fight avoidance skills were significantly protective against perpetration of both relational aggression and physical violence. In conclusion, findings suggest that clinicians providing services to adolescent girls involved in high risk behaviors assess and foster girls' development of stress management and fight avoidance skills to help reduce their risk of involvement in relational violence and physical fighting.

Trauma, Race, and Risk for Violent Felony Arrests Among Florida Juvenile Offenders

This study tests the assumptions of the The Childhood Trauma Model, which proposes that marginalized populations are both more likely to have traumatic childhoods and more criminalized than those in the upper echelons of society. It hypothesizes that traumatic childhood experiences increase risk of being sanctioned for violent behavior, and risks are amplified for minority and disadvantaged groups. The study finds that experiencing three or more traumas had a 200% to 370% increased chance of being arrested for a violent felony as youth who experienced a single traumatic event, and Blacks had up to 300% increased risk than Whites with equal trauma scores.

Organized Activity Participation and Relational Aggression: The Role of Positive Youth Development

Relational aggression among early adolescents is a pervasive problem that negatively influences the health and well-being of youth. Strength-based approaches such as positive youth development (PYD) are a promising way to reduce risk of detrimental outcomes such as relational aggression. Participation in organized activities is a key way that youth build assets related to PYD. Yet, few researchers have examined empirically assets related to PYD as a mechanism by which organized activity participation may help reduce risk of relational aggression. In this study, we used structural equation modeling to investigate if assets associated with PYD mediate the relationship between organized activity participation and relational aggression using survey data from a diverse, school-based sample of early adolescents (N = 196; mean age = 12.39 years; SD = 0.52; 60% female; 45% African American, 27% White, 21% multiracial, and 7% other, 71% economically disadvantaged). We tested 2 competing models, 1 with decomposed PYD factors and 1 with an integrated PYD factor. Our results suggest that PYD better fit as an integrated versus decomposed construct, providing support for the notion that youth benefit most from assets related to PYD when they operate collectively. Our results also provide support for PYD-related factors as a mechanism by which participation may reduce risk of relational aggression. Limitations of this study, and implications for prevention are discussed.

Ten-Year Secular Trends in Youth Violence: Results From the Philadelphia Youth Risk Behavior Survey 2003-2013

BACKGROUND

Youth violence reduction is a public health priority, yet few studies have examined secular trends in violence among urban youth, who may be particularly vulnerable to numerous forms of violence. This study examines 10-year secular trends in the prevalence of violence-related behaviors among Philadelphia high school students.

METHODS

Repeated cross-sectional data were analyzed from 5 waves of the Philadelphia Youth Risk Behavior Survey (YRBS) from 2003 to 2013. Sex-specific multivariate regression models were used to examine secular trends in multiple types of violence, accounting for age, race/ethnicity, and sampling strategy.

RESULTS

In 2013, the most prevalent violent behavior was physical fighting among boys (38.4%) and girls (32.7%). Among girls, the prevalence of sexual assault and suicide attempts declined between 2003 and 2013 (β = -0.13, p = .04 and β = -0.14, p = .007, respectively). Among boys, significant declines in carrying a weapon (β = -0.31, p < .001), carrying a gun (β = -0.16, p = .01), and physical fighting (β = -0.35, p = .001) were observed.

CONCLUSIONS

Whereas the prevalence of some forms of violence stabilized or declined among Philadelphia youth during 2003-2013 time span, involvement in violence-related behaviors remains common among this population. Continued surveillance and evidence-based violence reduction strategies are needed to address violence among urban youth.

Trends in Emergency Department Visits for Nonfatal Violence-Related Injuries Among Adolescents in the United States, 2009-2013

PURPOSE

Violence-related injuries are a major cause of death and disability among adolescents in the United States. The objective of this study was to examine trends in adolescent violence-related injuries between 2009 and 2013.

METHODS

This study examined data from the National Electronic Injury Surveillance System-All Injury Program for years 2009-2013. Linear regression was used to assess trends in rates of violence-related injuries among adolescents aged between 10 and 19 years.

RESULTS

We found overall rates of nonfatal violence-related injuries among all adolescents did not change significantly across the study years (p = .502). However, self-harm injury rates have significantly increased among female and younger adolescents during the period (p = .001 and .011, respectively).

CONCLUSIONS

Our results indicate that the overall intentional injury rates in adolescents have been stable; however, rates of self-injury have significantly increased in younger adolescents and females. Future research should focus on exploring causes of increases in self-harm injuries in these subpopulations.

Association between mobile phone use and inattention in 7102 Chinese adolescents: a population-based cross-sectional study

BACKGROUND

The dramatic growth of mobile phone (MP) use among young people has increased interest in its possible health hazards in this age group. The aim of this cross-sectional study was to investigate the association between MP use and inattention in adolescents.

METHODS

A total of 7720 middle school students were involved in this cross-sectional study. Inattention was assessed as defined for the Attention Deficit component of Attention deficit/Hyperactivity disorder (ADHD) by the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev. [DSM-IV-TR]). The demographic characteristics and information on MP use were included in the questionnaire. Chi-square tests and logistic regression models were used to analyze the data.

RESULTS

In total, 7102 (91.99%) valid questionnaires were obtained. After adjusted for confounders, inattention in adolescents was significantly associated with MP ownership, the time spent on entertainment on MP per day, the position of the MP during the day and the mode of the MP at night. The strongest association between inattention and the time spent on the MP was among students who spent more than 60 minutes per day playing on their MP.

CONCLUSIONS

Our study shows some associations between MP use and inattention in Chinese adolescents. Decreasing MP usage to less than 60 minutes per day may help adolescents to stay focused and centered.
