A study examined the effects of progressive relaxation training on the disruptive behaviors of a 12-year-old boy with autism. The participant acquired progressive relaxation skills, displayed more relaxed behavior after performing the procedures, and showed a decrease in the duration of his disruptive behavior upon completing progressive…

As in studies of self-control, a tit-for-tat contingency in an iterated prisoner's dilemma game creates a conflict between maximization of local and global reinforcement. The present experiments examine this conflict in a multiplayer prisoner's dilemma game. Versus tit for tat, cooperation corresponds to self-control; defection, always immediately…

Stereotypy is a relatively common behavioral disorder displayed by individuals with developmental disabilities, including autism. In this paper, we review selected studies on neurobiological interpretations of stereotypy and pharmacological interventions for stereotypy. Specifically, we review studies that evaluated the effects of serotonin uptake…

We conducted functional analyses and identified reinforcers for problem behavior for three individuals with developmental disabilities. Based on results of the functional analysis, we evaluated the rate, probability, delay, and duration of reinforcement for problem and appropriate behavior during descriptive parent-child observations. Results…

In the current investigation, we evaluated the effects of open and closed economies on the adaptive behavior of 2 individuals with developmental disabilities. Across both types of economy, progressive-ratio (PR) schedules were used in which the number of responses required to obtain reinforcement increased as the session progressed. In…

The effects of variable-interval (VI) and fixed-ratio (FR) schedules of reinforcement for work-related behavior and an organizer for the work materials (behavioral prosthesis) were evaluated with 3 adults with severe or profound mental retardation. The participants had been recommended for study because of high rates of off-task and aberrant…

Research has focused on increasing the treatment integrity of school-based interventions by utilizing performance feedback. The purpose of this study was to extend this literature by increasing special education teachers' treatment integrity for implementing antecedent and consequence procedures in an ongoing behavior support plan. A multiple…

We evaluated an enriched teaching program for reducing resistance and indices of unhappiness displayed by 3 individuals with profound multiple disabilities during teaching sessions. The program involved presentation of preferred activities before, during, and after each teaching session, discontinuation of identified nonpreferred activities, and a…

Psychosocial treatment options are nearly as broad as the behavioral problems that they address. With literally hundreds of treatment approaches available, how should clinicians select the most appropriate and effective intervention? One way is to consider using only those treatments with evidence of therapeutic efficacy. Indeed, funding agencies…

Recent studies have demonstrated that the working alliance predicts treatment outcome for partner violent men. This study examined the influence of personality and interpersonal characteristics, motivational readiness to change, and demographic factors on working alliance formation among a sample of men (N = 107) participating in a…

This study evaluated the efficacy of 2 brief interventions for cannabis-dependent adults. A multisite randomized controlled trial compared cannabis use outcomes across 3 study conditions: (a) 2 sessions of motivational enhancement therapy (MET); (b) 9 sessions of multicomponent therapy that included MET, cognitive-behavioral therapy, and case…

The relationship between major depressive disorder (MDD), treatment modality, and mood was evaluated in smokers participating in cessation programs. Participants (N = 549, 53.7% women, 46.3% men, 28% endorsing past MDD episodes) were randomly assigned to a cognitive-behavioral treatment (CBT) or health education (HE) intervention. Participants…

This meta-analysis summarizes results from 30 randomized experiments that compare behavioral marital therapy with no-treatment control with distressed couples. Results showed that behavioral marital therapy is significantly more effective than no treatment (d=.585). Although behavioral marital therapy research studies tend to be conducted under…

There has been little research on the effectiveness of different training strategies or the impact of exposure to treatment manuals alone on clinicians' ability to effectively implement empirically supported therapies. Seventy-eight community-based clinicians were assigned to 1 of 3 training conditions: review of a cognitive-behavioral therapy…

In this study, the authors examined the 2-, 3-, and 4-year outcomes of a school-based, universal approach to the prevention of adolescent depression. Despite initial short-term positive effects, these benefits were not maintained over time. Adolescents who completed the teacher-administered cognitive-behavioral intervention did not differ…
