|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 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

|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...
|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

|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
