The explosion in the rate of multiple births has led to new questions about how adequately prepared parents are for the demands of raising triplets and the implications for the healthy development of the infants. The authors examined the relationship between mothering, infant social behavior, and cognitive development in a longitudinal study of 23…

When efficacious interventions are implemented in real-world conditions, it is important to evaluate whether or not the programs are practiced as intended. This article presents the Fidelity of Implementation Rating System (FIMP), an observation-based measure assessing competent adherence to the Oregon model of Parent Management Training (PMTO).…

This represents one of a series of studies of the Longitudinal Emergency Medical Technician Attributes and Demographics Study (LEADS) being undertaken by the National Registry of Emergency Medical Technicians and the National Highway Traffic Safety Administration (NHTSA). This secondary analysis of the LEADS database, which provides a…

We have previously reported in this journal that spatial ability influences academic performance in engineering. We have also reported that spatial ability is trainable, and can be increased through instruction focused on using perception and mental imagery in three-dimensional representation. In this article, we present the results of a…

Ratings of the research training environment (RTE) and Holland personality type from 325 counseling psychology students who participated in G. M. Royalty, C. J. Gelso, B. Mallinckrodt, and K. Garrett's (1986) study were examined as predictors of the students' research productivity 15 years later. Graduates' research productivity was determined by…

This study tested a partial version of R. W. Lent, S. D. Brown, and G. Hackett's (1994) social-cognitive career theory model. Among 204 high school girls who attended science, math, and engineering (SME) career conferences, the authors used a 4-year longitudinal design to predict the choice of an SME college major and SME self-efficacy and outcome…

This paper reports on an exploratory, longitudinal study that analyzes and interprets the evolution of teachers' beliefs regarding learning, teaching, and technology, and their instructional practices, in the context of integrating technology-based information-rich tasks in six 4th-6th grade classrooms. The study used multiple research tools,…

Twenty-nine years ago Minnesota Longitudinal Study of Parents and Children (MLSPC) was launched at the Institute of Child Development, University of Minnesota. It was one of the first prospective longitudinal studies of how parent-infant attachment develops, how it changes over time, and how the quality of attachment in infancy influences…

Timetables for adolescents' behavioural autonomy were examined using a modified version of Feldman and Quatman's (1988) teen timetable measure with 73 middle-class African American middle adolescents (M age = 14.96 years, SD = 1.29) and their parents (73 mothers and 44 fathers), who were followed longitudinally for 3 years. African American…

This methodological investigation examines the accuracy of narrative-based scaled ratings covering several post high school years. Guided narratives by young adults described developmentally relevant behaviour and context for each month between ages 17 and the mid-20s. "Prospective" narratives covered shorter time periods in three interviews…

This article argues that the conclusions of previous research on the impact of sentencing guidelines may be misleading due to the cross-sectional methodologies employed in these studies. This study will suggest that a theoretically driven longitudinal analysis of mandatory guidelines offers a more appropriate way to study these policies.…

This longitudinal study investigated the relative contributions of infant temperament, maternal sensitivity, and psychosocial risk to individual differences in preschool children's cognitive development. It also examined specific moderating effects between predictors as well as the specific mediating role of maternal sensitivity in the relation…

This study estimated reading achievement gaps in different ethnic, gender, and socioeconomic groups of 1st graders in the U.S. compared with specific reference groups and identified statistically significant correlates and moderators of early reading achievement. A subset of 2,296 students nested in 184 schools from the Early Childhood…

Purpose: The purpose of this study was to examine and compare the development of proto-imperative and proto-declarative utterances in normally developing, non-neonatally screened, profoundly deaf toddlers. Method: Both types of proto-declarative are considered to be the most basic prelinguistic and early linguistic communicative functions.…

Twenty-four children with autism were randomly assigned to a clinic-directed group, replicating the parameters of the early intensive behavioral treatment developed at UCLA, or to a parent-directed group that received intensive hours but less supervision by equally well-trained supervisors. Outcome after 4 years of treatment, including cognitive,…
