Effectiveness of a collaborative, student-run campaign to increase safety belt use among adolescents.

BACKGROUND: MVCs are the leading cause of death among adolescents. Seat belts have been shown to decrease MVC-related death. The purpose of this retrospective cohort study was to evaluate the effectiveness of a community-supported, student-run campaign to increase safety belt use among adolescents in Southwest Florida. METHODS: We reviewed results of campaigns at 14 high schools from 2012 to 2018. The primary outcome was change in rates of student-driver seat belt use over the course of each campaign. Secondary outcomes included trends in seat belt use and MVC-related fatalities over the study period. Wilcoxon signed-rank test was used to compare rates of seat belt use before and after each intervention and over the course of the study period. Multivariate logistic regression was used to estimate the independent effects of demographic covariates on outcomes. RESULTS: Altogether, 85 campaigns were reviewed. A total of 8500 preintervention and 8500 postintervention observations of student seat belt use were assessed. The median rate of seat belt use increased from 82% prior to the intervention to 87% following the intervention (p<0.001). We did not detect a sustained trend in seat belt use or MVC-related fatalities over the study period. On multivariate analysis, schools with a higher proportion of minority students were less likely to experience a substantial increase in seat belt use following the intervention (OR=0.17, 95% CI 0.03 to 0.84, p=0.030). CONCLUSION: This collaborative campaign resulted in a modest, short-term increase in seat belt use among high school students. Future studies should evaluate which interventions are most effective and how short-term increases in seat belt use can be sustained.

The Effect of Intimate Partner Violence on the Psychosocial Development of Toddlers.

This study used data from the National Survey of Child and Adolescent Well-Being II to examine the effects of intimate partner violence (IPV) on child-welfare-involved toddlers' psychosocial development. The sample was limited to toddlers aged 12 to 18 months with mothers who did ( n = 102) and did not ( n = 163) report IPV physical victimization. Multiple linear regression analyses showed, when compared with mothers who did not report IPV physical victimization, mothers who reported IPV physical victimization were more likely to have toddlers with higher levels of socioemotional and behavioral problems ( B = 5.06, p < .001). Conversely, delayed social competence was not associated with IPV ( B = -1.33, p > .05). Further analyses examining only toddlers with mothers who reported IPV physical victimization revealed, when compared with IPV-exposed toddlers who had a child welfare report of physical abuse as the primary maltreatment type, those with IPV as the primary maltreatment type were at lower risk of having socioemotional and behavioral problems ( B = -12.90, p < .05) and delayed social competence ( B = 3.27, p < .05). These findings indicate a significant concern regarding toddler psychosocial development when a mother has experienced IPV. This concern is even greater among IPV-exposed toddlers who experience physical abuse. We recommend child welfare workers assess for IPV. Once identified, early prevention and intervention services should be offered and tailored to the specific needs of IPV-affected families.

Review of biological mechanisms and pharmacological treatments of comorbid PTSD and substance use disorder.

Posttraumatic stress disorder (PTSD) and alcohol/substance use disorder (A/SUD) are frequently comorbid. Comorbidity is associated with poorer psychological, functional, and treatment outcomes than either disorder alone. This review outlines biological mechanisms that are potentially involved in the development and maintenance of comorbid PTSD and A/SUD including neurotransmitter and hypothalamic-pituitary-adrenal dysregulation, structural differences in the brain, and shared genetic risk factors. The literature regarding pharmacological treatments that have been investigated for comorbid PTSD and A/SUD is also reviewed. Empirical data for each proposed mechanism and pharmacological approach is reviewed with the goal of making recommendations for future research. This article is part of a Special Issue entitled 'Post-Traumatic Stress Disorder'.
