Youth Assets, Neighborhood Factors, Parental Income, and Tobacco Use: A Longitudinal Study of Health Disparities.

This study aimed to assess how the relationship between youth assets and future no-tobacco use among youth might differ according to race/ethnicity, neighborhood factors and socio-economic status. Five waves of annual data were collected from 1111 youth/parent pairs living in Oklahoma, USA who were randomly selected to participate in the Youth Asset Study (YAS). A marginal logistic regression model using all five waves of no-tobacco use, demographics, and their interaction was used to compare the change in tobacco use over time.

Demographic Factors Predict Disparities in Number of Assets Youth Possess.

Objectives: This study's purpose was to determine if youth race/ethnicity, youth age and sex, parent income and education, household wealth, family poverty, and family structure were prospectively associated with youth assets in a community-based sample of racially/ethnically and economically-diverse youth and their parents.

Methods: Five waves of data were collected annually (2003 to 2008) from youth (N = 1111; Mean age = 14.4 years, SD = 1.

Local Learning Collaboratives to Improve Quality for Chronic Kidney Disease (CKD): From Four Regional Practice-based Research Networks (PBRNs).

Background: Four practice-based research networks (PBRNs) participated in a project to increase the diffusion of evidence-based treatment guidelines for chronic kidney disease (CKD). A multicomponent organizational intervention engaged regionally proximal primary care practices in a series of facilitated meetings, referred to as local learning collaboratives (LLCs).

Methods: The 2-wave strategy began with 8 practices in each PBRN receiving practice facilitation and subsequently joining an LLC.

Team Science Approach to Developing Consensus on Research Good Practices for Practice-Based Research Networks: A Case Study.

Using peer learning strategies, seven experienced PBRNs working in collaborative teams articulated procedures for PBRN Research Good Practices (PRGPs). The PRGPs is a PBRN-specific resource to facilitate PBRN management and staff training, to promote adherence to study protocols, and to increase validity and generalizability of study findings. This paper describes the team science processes which culminated in the PRGPs.

Practice-based Research Network Research Good Practices (PRGPs): Summary of Recommendations.

Introduction: Practice-based research networks (PBRNs) conduct research in community settings, which poses quality control challenges to the integrity of research, such as study implementation and data collection. A foundation for improving research processes within PBRNs is needed to ensure research integrity.

Methods: Network directors and coordinators from seven U.
