Background: There is a high prevalence of challenging behaviors (CB) in adults with intellectual disability (ID), which lead to negative personal outcomes and diminished quality of life. Emerging evidence suggest attachment theory could be useful to address CB in adults with ID and lower the negative impact on their social environment. Methods: A…

Although many studies of personality and aggression focus on multidimensional traits and higher order personality disorders (e.g., psychopathy), lower order, unidimensional traits may provide more precision in identifying specific aspects of personality that relate to aggression. The current study includes a comprehensive measurement of lower…

The effects of noncontingent reinforcement (NCR) schedules on responding were assessed across two parameters: presence of signal and schedule density. Results indicated that signaled NCR schedules were correlated with greater overall reductions in responding and quicker reductions relative to NCR schedules without a signal. The clinical…

Information on violent behaviors, sociodemographic factors, consumption factors (assessed by the European version of the Addiction Severity Index…

Transactional theories of development suggest that displaying high levels of antisocial behavior early in life and persistently over time causes disruption in multiple life domains, which in turn places individuals at risk for negative life outcomes. We used longitudinal data from 1,137 primarily African American urban youth (49.1% female) to…

Results with preschool children were nonsupportive and, in fact, contrary to the general hypothesis that high external locus of control would be positively related to greater behavior adjustment problems, as has been found with some groups of older children and adults. (RL)

As hypothesized, external locus of control scores correlated significantly with locus of conflict scores, although this varied for both sex and for the type of behavior problems exhibited. The hypothesized relationship between anxiety and locus of conflict was not supported. (RL)

Testing the hypothesis that group-centered leadership leads to less problem behavior among emotionally disturbed adolescents, 20 male and female adolescents aged 14-18 (from Karitas Community in Crystal Springs, Mississippi) were divided into leader-centered and group-centered groups and exposed to 3 weekend camping experiences.
