Differential reinforcement of other behavior (DRO) is a commonly used reinforcement-based system for reducing problem behavior. DRO systems are particularly useful in that they are effective for the treatment of maladaptive behavior and can be individualized based on the needs of the learner. One possible way to enhance the effectiveness of DRO…

Functional communication training (FCT) is one of the most common treatments for challenging behavior and is considered an empirically supported practice for children and adolescents with autism spectrum disorder (ASD). However, no previous systematic review has evaluated the quality of FCT for adults with ASD, and the empirical support for this…

Background: Previous evaluations of community PBS teams have not investigated whether behaviour change is both statistically reliable and clinically significant. Few previous studies have reported quality of life (QoL) and social validity outcomes. Method: The present authors collected data on 85 people referred to a specialist PBS team. The…

Positive Behaviour Support is an applied behaviour analytic system of support that is utilised in schools and in residential care settings for children and adults with disabilities who engage in challenging behaviour. Implementation fidelity depends on appropriate staff training and organisational behaviour management. A systematic literature…

Introduction: The purpose of this study was to gain additional insight on patterns of behavior of three individuals dually diagnosed with intellectual disability (ID) and bipolar disorder as they cycled between elevated and depressed mood states. Methods: Data were collected from weekly, one-hour observations across a period of several months. The…

Background: Following scandals such as Winterbourne view, Department of Health, (A national response to Winterbourne View Hospital, 2012) seeks changes in challenging behaviour services. A key part of this change is ensuring people with learning disabilities who use challenging behaviour services have more personalised support and their voices are…

Data from previous studies are presented that demonstrate that community living for persons with intellectual and developmental disabilities (IDD) has improved in recent years, but that living in one's own home by these individuals is still a very rare outcome. Literature is presented that explains how living arrangements for adults with IDD have…

Primary school-aged children with conduct problems are at risk of future antisocial and criminal behaviour, particularly when there are additional family-level risk factors. However, little is known about how school-related factors can reduce that risk. This qualitative longitudinal study investigates school-related influences on changes in the…

The objective of this study was to assess the tolerability and efficacy of pregnenolone in reducing irritability in adults with autism spectrum disorder (ASD). This was a pilot, open-label, 12-week trial that included twelve subjects with a mean age of 22.5 ± 5.8 years. Two participants dropped out of the study due to reasons unrelated to adverse…

The present study examined trajectories of adaptive behavior, behavior problems, psychological symptoms, and autism symptoms in adolescents and adults with fragile X syndrome (n = 147) over a three-year period. Adaptive behavior significantly increased over time, particularly for adolescents, and the severity of behavior problems decreased over…

In the present study, we jointly employ and integrate variable- and person-centered approaches to identify groups of individuals with autism spectrum disorders (ASD) who have similar profiles of change over a period of 10 years across three critical domains of functioning: maladaptive behaviors, autism symptoms, and daily living skills. Two…

Little is known about outcomes for individuals with autism spectrum disorders (ASD) into adulthood. Several characteristics of individuals with ASD predict long-term outcomes, and the family environment may also play a role. The present study uses a prospective, longitudinal design to describe and predict trajectories of autism symptoms and…

This study examined the bidirectional relations over time between behavioral functioning (autism symptoms, maladaptive behaviors, activities of daily living) and vocational/educational activities of adults with autism spectrum disorders (ASD). Participants were 153 adults with ASD (M age = 30.2 years) who were part of a larger longitudinal study.…

The current study combined a management technique termed "Service Review" with performance scorecards to enhance staff and consumer behavior in a human service setting consisting of 11 supervisors and 56 front-line staff working with 9 adult consumers with challenging behaviors. Results of our intervention showed that service review and…

This study consists of three sub-studies. Sub-study 1 and 2 attempted to incorporate environmental variables as precursor background variables of the theory of planned behavior (TPB) to predict quitting-related intentions among Texas adult smokers and university student smokers, respectively. Sub-study 1 and 2 analyzed different data sets and were…
