Matching methods such as nearest neighbor propensity score matching are increasingly popular techniques for controlling confounding in nonexperimental studies. However, simple k:1 matching methods, which select k well-matched comparison individuals for each treated individual, are sometimes criticized for being overly restrictive and discarding…

Multiple methods are vital to understanding development as a dynamic, transactional process. This article focuses on the ways in which quantitative and qualitative methodologies can be combined to enrich developmental science and the study of human development, focusing on the practical questions of "when" and "how." Research situations that may…

There are a number of significant challenges researchers encounter when studying development over an extended period of time, including subject attrition, the changing of measurement structures across groups and developmental periods, and the need to invest substantial time and money. Integrative data analysis is an emerging set of methodologies…

Tested the hypothesis that development of secure attachments is predictable from synchronous, and insecure attachments from asynchronous interactions across the first year. Findings from 30 dyads (10 secure, 10 avoidant, 10 resistant) supported the hypothesis at one and three months, with synchronous interaction observed at significantly,…

Examines the psychometric properties of two procedures for reducing data from the Brazelton Neonatal Behavioral Assessment Scale: factor and cluster analysis. The sample consisted of 85 male and 77 female newborns. (RH)

Over 600 White females between 10.5 and 18.5 years of age were studied to test construct comparability across adolescence. Assessed were emotional functioning, eating problems, self-reflection, self-image, and mastery/adjustment to examine meaning equivalence in self-concepts and developmental psychopathology. Results suggest that the five factors…

Mothers of about 100 toddlers completed the Toddler Temperament Scale when their children were 12, 18, and 24 months old. Other data sets were available for: (a) factors representing laboratory observations; (b) measures of mothers' temperament by mothers and by social workers; and (c) measures of the home and family environment by social workers.…

Since early research had shown that a total score on 27 Piagetian tasks was very highly correlated with a Wechsler and achievement composite, a study investigated the possibility of shortening the Piagetian test by means of classical analysis methodology. (HOD)

Demonstrates the usefulness of the inclusion paradigm as a methodological tool in providing information about the conceptual breadth of selected social and nonsocial superordinate categories in children who exhibit some degree of inclusion logic. (HOD)

Reviews results of research related to the control system model of how parents and children regulate each other's behavior. Confirmed early formulations that postulated individual differences in children's assertiveness, activity, and person orientation as explanations for differences in parents' child-rearing techniques. (HOD)

Assessed the relation between behavior problem ratings and family relationship quality among 29 mothers and their 4-year-old children. Findings suggest that the absence of positive parental behaviors is as important as the presence of negative behaviors in behavior problem development. (RH)

Provides a comprehensive meta-analysis of gender differences in aggression; offers estimates of the magnitude of differences; provides a developmental analysis of effects for all ages for which data are available; and includes a total of 143 studies. Basic techniques of meta-analysis are presented and then applied to analyze studies of gender…

Considers the life stages of the Black extended family; research on the antecedents and consequences of extended family life; and social policy, clinical intervention, and family research implications of the Black extended family from the context of a broad conceptual and methodological definition of family.
