Background: People with intellectual disabilities are more at risk of obesity than the general population. Emerging literature indicates that multicomponent interventions are most effective, however, individual results are variable and little research exists as to why this is the case. Methods: Focus groups were conducted to explore lived…

This study assessed the effects of a contingency management (CM) intervention for alcohol consumption in 10 alcohol-dependent participants. An ABCA design was used. Vouchers were provided contingent on results of ethyl glucuronide (EtG) urine tests (an alcohol biomarker with a 2-day detection period) and alcohol breath tests during the C phase.…

We describe a clinical case study surrounding the behavioral assessment and operant treatment of, an adult with severe mental retardation who engaged in chronic breath-holding. In this clinical case, previous neurological and medical testing had ruled out biological bases for the individual's breath-holding. A functional behavioral assessment…

The development and interrelationship of various measures of independence in children ages 3-12 are examined. Subjects were scored on measures of locus of control and achievement motivation and were rated by teachers on independence and achievement. Subjects were also scored on reliance on adult evaluation and self-evaluation. The results showed…

The effects of reinforcement choice on task performance were examined with six individuals (ages 6-39) who had been diagnosed with severe to profound mental retardation. Findings indicated that access to choice did not improve the task performance of the subjects when highly preferred items were already incorporated into instructional programs.…

Reviews studies related to physical exercise with people with severe and profound developmental disabilities and comments on the main findings and on the practicality and acceptability of physical exercise. The use of technical instruments combined with reinforcing events to ensure mild physical exercise is discussed. (Author/CR)

Experiments examined the effect of work requirements in combination with reinforcement schedules on the choice behavior of six adults with mental retardation and seven typical preschoolers. Results showed that participants' responding was largely controlled by the reinforcement received for responding to each level of work. (Author/CR)

A comprehensive evidence-based treatment for substance abuse and other associated problems (Family Behavior Therapy) is described, including its application to both adolescents and adults across a wide range of clinical contexts (i.e., criminal justice, child welfare). Relevant to practitioners and applied clinical researchers, topic areas include…

Three forms of auditory stimulation were compared as reinforcers with 13 severely mentally retarded adults performing a task to promote cardiovascular fitness. Subjects received stimulation if they pedalled at a specified rate above baseline performance. Results indicated that music was an effective reinforcer in promoting continuous work output,…

This study compared the addition of two self-management strategies to typical supervision to improve productivity of eight mentally retarded workers in a sheltered workshop. Both strategies--(1) self monitoring plus goal setting and social contingencies and (2) addition of a monetary bonus for productivity--were equally effective in improving…

Intrinsic motivation and self-reinforcement can be used identically to explain behavioral persistence in the absence of external reward. Yet the relationship between these concepts has not been adequately explored. Since intrinsic motivation appears to be dependent on an interesting task and self-reinforcement independent of task, it was…

This study examined three maladaptive behaviors, self-injurious behavior (SIB), stereotypies, and aggression in 36 adults with either autism, pervasive developmental disorder not otherwise specified (PDD-NOS), and mental retardation. Findings indicated that, for all three diagnostic categories, aggression was primarily maintained for attentional…

This technical paper is one of three produced by a large-scale effort aimed at implementing a new approach to measuring productivity, and using that approach to assess the impact of feedback, goal setting, and incentives on productivity. The productivity measurement system was developed for five units in the maintenance and supply areas at an Air…

The monograph reports the problem, design, and findings of graduate student research directly related to adult basic education teacher training. The objectives of this experiment were to assess: (1) the degree of relationship among reinforcement, learning, and self-concept for adults using computer assisted instruction (CAI); (2) changes in…
