Aggressive behaviors in children and adolescents have undergone important conceptual and definitional modifications in the past two decades. In particular, subtypes of aggression have been proposed that separate the form and the function of the aggressive behaviors (i.e., social vs. physical aggression; reactive vs. proactive aggression).…

To the extent that brain dysfunction is present in violence-prone groups, one may expect that assessment of simple perceptual and cognitive abilities may facilitate significantly the detection of subjects prone to violent behavior. This research examines the ability of neuropsychological tests to discriminate between violent and nonviolent…

A stable, ordered dominance hierarchy was found via observational and sociometric methods for a group of 13-year-old boys during a five-week summer camp. This group structure was formed early in camp and was stable across settings, time, and types of dominance interactions. The hierarchy correlated significantly with the rank-orderings bed…

Adolescent parenthood was investigated based on a large panel study known as the National Longitudinal Study of the High School Class of 1972 (NLS) which has tracked over 22,000 adolescents who are now in their early 20's and have experienced many of the near-term consequences of early parenthood. Procedures for creating variables that mark entry…

An empirically based paradigm for assessment and taxonomy of child, adolescent, and young adult behavioral and emotional problems is outlined, and the standardization procedures used to assess problems reported by different informants for large clinical samples are discussed. The application of the paradigm to new cases is considered. (SLD)

This article describes the prevalence of different types of functional assessment and analysis procedures reported in articles in the "Journal of the Association for Persons with Severe Handicaps" (JASH) involving individuals exhibiting problem behaviors. The most frequently reported functional assessment approach was the use of structured direct…

Past research based primarily on cross-sectional data, has suggested a Guttman scale of substance use onset where marijuana use is preceded by alcohol use, and where sometimes tobacco is placed between alcohol and marijuana. Prospective longitudinal data is needed to determine whether the stages form a temporal sequence. A new statistical…

A phenomenological investigation was conducted to examine the causal factors of adolescent substance abuse. Results indicated the adolescent substance abuser sees life as a struggle, sees self as an outsider, feels powerless and uses drugs to cope with anxiety. (RC)

Research on family interaction patterns suggests that delinquent behaviors of children and adolescents may be related to, if not a direct function of, disordered interpersonal interaction within the family unit. Family interaction can be seen as a sequence of interlocking events occurring over time and consisting of the three basic characteristics…

The paper presents an overview of an ethological approach to the study of abnormal human behavior and a review of research using ethological approaches (with an emphasis on autism research). Ethology is defined as the study of behavior as it occurs in its natural habitat. The four types of questions ethologists ask about behavior, such as what is…

The author conducted two studies of disturbed adolescents in an effort to specify the precursors of severe psychopathology in adulthood, particularly the schizophrenic spectrum of disorders. In the prospective study 35 disturbed adolescents were followed for a five-year period from age 16 to 21. Numerous measures were taken on the target…

The perceptions of students toward conservation and nature utilization and their behavior toward the environment were studied with 725 Danish adolescents and a previously studied group of Bavarian adolescents. Following construct validation, comparison of mean within-region factor values reveals substantial differences between countries. (SLD)

Adolescents and young adults are likely to be sexually active and interested in sexual ethics. In order to tap into this interest and assist in their intellectual development, a sexual ethics continuum teaching strategy was developed during four semesters with six sections of two different college courses. A total of 52 behaviors of interest to…

A beginning step in understanding intrinsic motivation in school can occur through examination of adolescents' subjective experience and the relationship between enjoyment and school learning. Subjects (85) filled out self-report forms, recording their level of concentration, moods, feelings and activities at random times during the waking hours…

Health risk behaviors (substance use, violence, suicide, and car safety) of 194 African American urban adolescents with mild mental retardation were measured using either a confidential individual interview or an anonymous group survey. The survey methodology resulted in disclosure of more risk behaviors than the interview methodology. Elevated…
