We examined three interrelated questions: (1) Who selects physically aggressive friends? (2) Are physically aggressive adolescents influential? and (3) Who is susceptible to influence from these friends? Using stochastic actor‐based modeling, we tested our hypotheses using a sample of 480 adolescents (ages 11–13) who were followed across four assessments (fall and spring of 6th and 7th grade). After controlling for other factors that drive network and behavioral dynamics, we found that physically aggressive adolescents were attractive as friends, physically aggressive adolescents and girls were more likely to select physically aggressive friends, and peer‐rejected adolescents were less likely to select physically aggressive friends. There was an overall peer influence effect, but gender and social status were not significant moderators of influence.

Purpose: To examine changes in organizations' workplace health promotion (WHP) initiatives over time associated with repeated self-assessment using the Well Workplace Checklist (WWC). Design: Well Workplace Checklist data include a convenience sample of US organizations that selected to assess their performance against quality WHP benchmarks. Setting: Workplaces. Subjects: In total, 577 US organizations completed the WWC in 2 or more years from 2008 to 2015. Measures: The WWC is a 100-item organizational assessment that measures performance against the original set of quality benchmarks that were established by the Wellness Council of America (WELCOA). Analysis: This study examined changes in overall WWC scores as well as 7 separate benchmark scores. Multilevel modeling was used to examine changes in scores associated with repeated assessments, controlling for the year of assessment and organizational characteristics. Results: There were significant increases in overall WWC scores (β = 2.93, P < .001) associated with the repeated WWC assessments, after controlling for organizational characteristics. All 7 benchmark scores had significant increases associated with reassessment. Compared to other benchmarks, operating plan (β = 6.18, P < .001) and evaluation (β = 4.91, P < .001) scores increased more with each reassessment. Conclusion: Continued reassessment may represent more commitment to and investment in WHP initiatives which could lead to improved quality. Other factors that may positively influence changes in performance against benchmarks include company size, access to outside resources for WHP, and a history with implementing WHP.

Few studies have examined disparities in adverse birth outcomes and compared contributing socioeconomic factors specifically between African-American and White teen mothers. This study examined intersections between neighborhood socioeconomic status (as defined by census-tract median household income), maternal age, and racial disparities in preterm birth (PTB) outcomes between African-American and White teen mothers in North Carolina. Using a linked dataset with state birth record data and socioeconomic information from the 2010 US Census, disparities in preterm birth outcomes for 16,472 teen mothers were examined through bivariate and multilevel analyses. African-American teens had significantly greater odds of PTB outcomes than White teens (OR = 1.38, 95% CI 1.21, 1.56). Racial disparities in PTB rates significantly varied by neighborhood income; PTB rates were 2.1 times higher for African-American teens in higher income neighborhoods compared to White teens in similar neighborhoods. Disparities in PTB did not vary significantly between teens younger than age 17 and teens ages 17–19, although the magnitude of racial disparities was larger between younger African-American and White teens. These results justify further investigations using intersectional frameworks to test the effects of racial status, neighborhood socioeconomic factors, and maternal age on birth outcome disparities among infants born to teen mothers.
