|Adolescent Peer Networks and the Potential for the Diffusion of Intervention Effects
||Many evaluation studies assess the direct effect of an intervention on individuals, but there is an increasing interest in clarifying how interventions can impact larger social settings. One process that can lead to these setting-level effects is dif...
|Brothers leading healthy lives: outcomes from the pilot testing of a culturally and contextually congruent HIV prevention intervention for black male college students
||We used a treatment group-only design to pilot test a newly developed intervention to increase condom use among higher risk heterosexually active African American/black male college students. A community-based participatory research partnership devel...
|Competence and African American Children in Informal Kinship Care: The Role of Family
||African American children are more likely than any other racial or ethnic group to live in kinship care, yet there is little empirical knowledge available to help understand the attributes of these families that contribute to children's development o...
|Delinquency and peer acceptance in adolescence: A within-person test of Moffitt’s hypotheses
||We tested 2 hypotheses derived from Moffitt’s (1993) taxonomic theory of antisocial behavior, both of which are central to her explanation for the rise in delinquency during adolescence. We tested whether persistently delinquent individuals become mo...
|Delinquency and the Structure of Adolescent Peer Groups
||Gangs and group-level processes were once central phenomena for criminological theory and research. By the mid-1970s, however, gang research primarily was displaced by studies of individual behavior using randomized self-report surveys, a shift that ...
|Density or Distinction? The Roles of Data Structure and Group Detection Methods in Describing Adolescent Peer Groups
||Despite cross-disciplinary interest in social influence among adolescent peer groups, significant variations in collecting and analyzing peer network data have not been explored, so it is difficult to disentangle substantive and methodological differ...
|Diffusion of intervention effects: The impact of a family-based substance use prevention program on friends of participants
||PurposeWe tested whether effects of the Strengthening Families Program for Youth 10–14 (SFP10-14) diffused from intervention participants to their friends. We also tested which program effects on participants accounted for diffusion.MethodsData are f...
|Dynamic Social Networks and Physical Aggression: The Moderating Role of Gender and Social Status Among Peers
||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 test...
|Estimation of a four-parameter item response theory model
||We explore the justification and formulation of a four-parameter item response theory model (4PM) and employ a Bayesian approach to recover successfully parameter estimates for items and respondents. For data generated using a 4PM item response model...
|I’ve Fallen and I Can’t Get Up: Can High-Ability Students Recover From Early Mistakes in CAT?
||A difficult result to interpret in Computerized Adaptive Tests (CATs) occurs when an ability estimate initially drops and then ascends continuously until the test ends, suggesting that the true ability may be higher than implied by the final estimate...
|Innovative Research Exploring the Effects of Physical Activity and Genetics on Cognitive Performance in Community-Based Older Adults
||Physical activity is predictive of better cognitive performance and lower risk of Alzheimer’s disease (AD). The apolipoprotein E gene (APOE) is a susceptibility gene for AD with the e4 allele being associated with a greater risk of AD. Cross-sectiona...
|Laying the Groundwork for Evidence-Based Public Health: Why Some Local Health Departments Use More Evidence-Based Decision-Making Practices Than Others
||We examined variation in the use of evidence-based decision-making (EBDM) practices across local health departments (LHDs) in the United States and the extent to which this variation was predicted by resources, personnel, and governance. We analyzed ...
|Moving beyond the treatment package approach to developing behavioral interventions: addressing questions that arose during an application of the Multiphase Optimization Strategy (MOST)
||Given current pressures to increase the public health contributions of behavioral interventions, intervention scientists may wish to consider moving beyond the classical treatment package approach that focuses primarily on achieving statistical signi...
|Peer Influences on Academic Motivation: Exploring Multiple Methods of Assessing Youths’ Most “Influential” Peer Relationships
||The present study examines the relative role of three distinct types of peer relationships (reciprocated friendships, frequent interactions, and shared group membership) in within-year changes in academic self-concept and engagement before and after ...
|Race, Socioeconomic Status, and Age: Exploring Intersections in Preterm Birth Disparities among Teen Mothers
||Few studies have examined disparities in adverse birth outcomes and compared contributingsocioeconomic factors specifically between African-American and White teen mothers. Thisstudy examined intersections between neighborhood socioeconomic status (a...
|Rejection, feeling bad, and being hurt: Using multilevel modeling to clarify the link between peer group aggression and adjustment
||The association between affiliating with aggressive peers and behavioral, social and psychological adjustment was examined. Students initially in 3rd, 4th, and 5th grade (N = 427) were followed biannually through 7th grade. Students’ peer-nominated g...
|A Reputation for Success (or Failure) : The Association of Peer Academic Reputations With Academic Self-Concept, Effort, and Performance Across the Upper Elementary Grades
||Studies of the socialization of achievement-related beliefs and academic skills typically focus on the influence of teachers and parents (Eccles, Wigfield, & Schiefele, 1998; Guay, Boivin, & Hodges, 1999; Guay, Marsh, & Boivin, 2003; Harter, 1998), b...
