Although there has been considerable research which has explored factors related to internet addiction, few studies have investigated elementary school students' involvement in this behaviour pattern. Participants in the present study were 1045 children in grades 3 to 6 from elementary schools in Taiwan. Students completed surveys on their use of…

The present study examined the joint development of substance use and externalizing problems in early and middle adolescence. First, it was tested whether the relevant groups found in previous studies i.e., those with an early onset, a late onset, and no onset or low levels of risk behavior could be identified, while using a developmental model of…

The goal of this study was to examine initial levels and rates of change in the intensity and breadth of participation in organized activities during the adolescent years, and how these participation practices were related to youth outcomes in later adolescence. The main objectives were (a) to examine growth curves of intensity and breadth of…

The Hand Test was administered to 107 maximum-security prison inmates. The Acting Out Score (AOS) was computed, and one year later, actual acting out for the same inmates was recorded. Determined that the Hand Test AOS is useful in identifying inmates who have potential for acting out. (Author)

Clinicians need to know the likelihood of a condition given a positive or negative diagnostic test. In this study a Bayesian analysis of the Clinical Behavior Checklist for Persons with Intellectual Disabilities (CBCPID) to predict depression in people with intellectual disability was conducted. The CBCPID was administered to 92 adults with…

This study examined whether female undergraduate students who share with male undergraduates similar demographics, perceptions, and alcohol use locations, also share similar alcohol usage patterns, negative consequences, and predictors for both. Secondary analysis was conducted using 1992 and 1993 U.S. Department of Education Core Survey data…

Examined cognitive and personality patterns of 84 court-referred adolescents to identify predictors of recurrent delinquent behavior. It was found that continued behavioral problems at follow-up were more likely in adolescents with discrepancies between Verbal and Performance intelligence quotient or large differences between "neurotic" and…

Studied predictors of alcohol use and misuse in 1,823 college students who completed the Student Alcohol Information Survey. Results showed students who began drinking younger reported more alcohol-related problems. Students introduced to alcohol with parental consent, who were the majority, experienced significantly fewer problems. (JAC)

Analysis of questionnaires completed by parents of young children with either Prader-Willi syndrome (N=84), Down syndrome (N=56), or typically developing (N=86), found children with Prader-Willi exhibited more compulsions, skin-picking, and tantrums than did the other groups. Discriminant analysis identified two functions (developmental milestones…

A study examined the relationship between neuroimaging findings and the behavioral characteristics of 29 patients with tuberous sclerosis. Findings indicate a positive linear relationship between a patient's total number of tubers and degree of intellectual impairment. The number of tubers in the cerebellum was associated with more autistic…

This study addresses the utility of the resilient, overcontrolled, and undercontrolled personality prototypes for predicting children's and adolescents' problem behaviour in a longitudinal general population sample (N = 491). Both parents and one child participated in the study at two measurement occasions separated by a 3-year interval. The major…

Examined mother-child interaction predictors of initial levels and changes in child aggressive and disruptive behavior at school from kindergarten to third grade in 585 mother-child dyads. Found that for boys, high coercion and nonaffection were particularly associated with the high-increasing-aggression trajectory, but for girls, high levels of…

Maladaptive behavior of 43 children (ages 4-19) with Prader-Willi syndrome was compared to children with Down syndrome and nonspecific mental retardation. The children with Prader-Willi showed more frequent and severe internalizing, externalizing, and total problem behaviors. Certain maladaptive behaviors were distinctive to these children and…

Changes in patterns of maladaptive behavior related to age-associated adaptive declines were investigated in 529 adults with mental retardation (ages 30 to 84), 202 with Down syndrome. Certain maladaptive behaviors were related to the onset of adaptive declines, (e.g., lack of boundaries). Findings suggest similarities in the course of…

Determined whether there are developmental precursors to accidents and resulting physical impairment. Data collected at ages 8 and 14 (147 males and 142 females) were related to the number of types of accidents and impairment by the age of 27. Accidents and impairment were most frequent among individuals whose behavior had been characterized by…
