The articles in this Special Topic issue present a range of assessment models and challenges for improving the identification and early intervention of students in need of additional supports. Although each article targets a unique aspect of student learning (learning behaviors, math skills, reading comprehension, behavioral functioning, and…

Previous research suggests that the prevalence of aggression is high among low-income urban youth who have to cope with a number of psychological stressors. Less is known about the early development and consequences of aggression and peer victimization prior to adolescence in these contexts. This study examined the correlates, interplay, and…

A substantial body of data and a number of reviews of the literature on risk encouraged this attempt to construct a theoretically consistent approach to research on risk. Much of the research can be seen as attempting to estimate the probability that development will be compromised for groups of infants born under different circumstances. Linear…

The conceptualizations of morphogenic processes suggested by systems theorists provide a useful framework for describing growth and development in complex adaptive self-directing organisms. These processes involve changes in (1) a system's structure, state, or functioning; (2) discontinuities in development; and (3) at least two kinds of…

A biopsychosocial model of the development of adolescent chronic conduct problems is presented and supported through a review of empirical findings. The model posits that biological dispositions and sociocultural contexts place certain children at risk in early life but that life experiences with parents, peers, and social institutions increment…

Applied a semiparametric mixture model to a sample of 284 low-income boys to model developmental trajectories of overt conduct problems from ages 2 to 8. Identified four trajectories: persistent problem, high-level desister, moderate-level desister, and persistent low. Initially high and low groups were differentiated in early childhood by high…

Used data from National Longitudinal Survey of Youth to model developmental trajectories across middle childhood. Found that individual trajectories were extremely diverse in level and sometimes in slope. Compared to girls, boys had heterogeneous slopes for math and behavior problems. Compared to boys, girls showed a significantly higher degree of…

Examined relations between early family risk and later maladaptive social information processing and conduct problems among 178 economically disadvantaged boys. Found that early childhood assessments of disadvantage and maternal depression predicted boys' maladaptive response generation and conduct problems at age 10, accounting for 6 and 14…

The problem of children's misbehavior in school is an urgent concern. Although misbehavior is not unique to the school, the whole of society suffers from violence. It is important to recall that those committing crimes today were yesterday's students. There are two modes for discipline in the schools. The "established" mode aims for teacher…

Examined contributions of different risk factors to predicting children's psychological and academic outcomes at end of first grade. Found that each analysis level contributed to prediction of most outcomes; 18 to 29% of outcome variance was predicted; a common set of predictors predicted numerous outcomes; ethnicity showed little unique…

This study examined antecedents to early patterned alcohol and tobacco use and marijuana experimentation between ages 11 and 16 for an at-risk male sample. Findings suggested that family, peer, and child characteristics were inextricably connected within an ecology of development. A structural equation prediction model suggested a higher order…
