Developmental science rests on describing, explaining, and optimizing intraindividual changes and, hence, empirically requires longitudinal research. Problems of missing data arise in most longitudinal studies, thus creating challenges for interpreting the substance and structure of intraindividual change. Using a sample of reports of longitudinal…

Using data from Grades 5 to 7 of the longitudinal 4-H Study of Positive Youth Development (PYD), this research assessed the structure and development of PYD. Building on Grade 5 findings, that "Five Cs" (Competence, Confidence, Connection, Character, and Caring) could be empirically defined as latent constructs converging on a second-order…

Studying human development involves describing, explaining, and optimizing intraindividual change and interindividual differences in such change and, as such, requires longitudinal research. The selection of the appropriate type of longitudinal design requires selecting the option that best addresses the theoretical questions asked about…

Intentional self regulation and hopeful expectations for the future are theoretically-related constructs shown to lead to positive youth development (PYD). However, the nature of their relationship over time has not been tested. Therefore, this study explored the associations between hopeful future expectations and intentional self regulation in…

Theory and research suggest that structured, out-of-school-time activities, and in particular youth development programs aimed at promoting positive youth development (PYD), are key developmental assets for such development. Using longitudinal data from 945 fifth and sixth graders participating in the 4-H Study of PYD, initial descriptive…

The authors used data from Grades 5 through 7 of the longitudinal 4-H Study of Positive Youth Development to assess relations among sports participation, other out-of-school-time (OST) activities, and indicators of youth development. They used a mixture of variable- and pattern-centered analyses aimed at disentangling different features of…

The study of adolescent development rests on methodologically appropriate collection and interpretation of longitudinal data. While all longitudinal studies of adolescent development involve missing data, the methods to treat missingness that have been recommended most often focus on missing data from cross-sectional studies. The problems of…

Theories of positive youth development (PYD) regard such development as bases of both community contributions and lessened likelihood of risk/problem behaviors. Using data from the 4-H Study of PYD, we tested these expectations by examining if PYD in Grade 5 predicted both youth contributions and risk behaviors and depression in Grade 6. Results…

School bullying has negative implications for adolescent academic competence, making it important to explore what factors promote such competence for adolescents who bully and who are bullied. Potential contextual and individual variables linked to academic competence were examined in the context of bullying. Data were derived from the Grades 5…

The 4-H Study of Positive Youth Development (PYD), a longitudinal investigation of a diverse sample of 1,700 fifth graders and 1,117 of their parents, tests developmental contextual ideas linking PYD, youth contributions, and participation in community youth development (YD) programs, representing a key ecological asset. Using data from Wave 1 of…

Using data from Grades 5, 6, and 7 of the 4-H Study of Positive Youth Development (PYD), the role of intentional self-regulation in the positive development of young adolescents was examined through use of the Selection, Optimization, and Compensation (SOC) measure. Consistent with Gestsdóttir and Lerner (2007), results of confirmatory factor…
