To determine the effects of response–reinforcer arrangements on task performance and preference, participants completed tasks on accumulated and distributed response–reinforcer arrangements. Three males diagnosed with an autism spectrum disorder completed tasks before receiving 5-min or 30-seconds access to a preferred stimulus. To enhance discrimination between the two arrangements, color-coded token boards were used to represent each arrangement. Responding was evaluated within a multielement design to compare the response rate across conditions for each participant. A preference assessment was conducted after the comparison to determine whether a preference for one of the arrangements emerged. All participants produced a higher rate of responding in the accumulated schedule of reinforcement.

This study examined changes in child mealtime behavior, diet variety, and family mealtime environment after intensive interdisciplinary behavioral treatment (IIBT) for 52 children referred to a day treatment feeding program. Children fell into three developmental status groups including autism spectrum disorder (n = 16), other special needs (n = 19), and no special needs (n = 17), with some having no known medical problems (n = 22) and some having gastrointestinal, cardiopulmonary, and/or endocrine-metabolic problems (n = 28). At pre-intervention and post-intervention, caregivers completed the About Your Child’s Eating scale, the Brief Assessment of Mealtime Behavior in Children, and a food preference inventory of 70 common foods (20 fruits, 23 vegetables, 12 proteins, 8 grains, 7 dairy). Mixed-factor 2 × 3 ANOVAs compared each of the 11 feeding outcomes across the two study phases (pre-, post-intervention) for the three developmental status groups. All feeding outcomes except fruit acceptance showed significant improvements from pre- to post-intervention, with no main effects for developmental status, and no interaction effects. Additionally, mixed-factor 2 × 2 ANOVAs compared each of the 11 feeding outcomes across the two study phases (pre-, post-intervention) for children with and without medical problems. All feeding outcomes except fruit acceptance showed significant improvements from pre- to post-intervention, with no main effects for medical status, and no interaction effects. Present results suggest that IIBT is effective for improving a number of children’s feeding problems, regardless of their developmental or medical status.

An increasing number of children fail to meet the recommended levels of physical activity. The purpose of this study was to examine the effects of peer presence on variables that have been shown to evoke moderate-to-vigorous physical activity (MVPA) in children. We recorded the levels of MVPA in three preschool children across no adult, attention, and interactive play conditions, with a peer present and absent. All conditions were compared with a naturalistic baseline and presented in a multielement design with a brief reversal to baseline and reintroduction of the most effective condition. All three participants displayed most MVPA during the interactive play condition with a peer present. This study furthers research on the identification of variables that evoke MVPA in young children and emphasizes the interaction of peer presence and contingent social positive reinforcement as relevant variables.

The current study compared the effects of 15-min acceptance-based and cognitive reappraisal–based interventions on experiential avoidance (EA) in socially anxious college students who participated in an experimental public speaking task. Participants were randomly assigned to receive one of the two interventions designed to aid in preparation for a 5-min laboratory-based public speaking task. Results indicated that participants receiving the acceptance-based intervention reported significantly lower levels of EA at the post–public speaking task measurement time, indicating that this brief acceptance–based intervention yielded the proposed mechanism of action in the sample used for this study. These findings highlight the importance of process-based accounts of cognitive-behavioral psychotherapy and shed light on the importance of developing interventions for alleviating social anxiety.

The high-probability (high-p) instructional sequence is an intervention commonly used to increase compliance in a variety of skill domains, including compliance with low-probability (low-p) mealtime demands in children with pediatric feeding disorders. However, the effects of the high-p sequence on feeding have varied across studies, a systematic synthesis of the literature to guide practice and further research is lacking, and whether the high-p sequence, as an intervention for feeding problems, meets current evidence-based practice standards in special education is unknown. First, we conducted a systematic multistep search, identified seven studies that met inclusion criteria, and synthesized participant and study characteristics. Then we compared the evidence with the 2014 Council for Exceptional Children (CEC): Standards for Evidence-Based Practices in Special Education. The results suggest that (a) the high-p sequence can improve compliance with low-p mealtime demands in young children with feeding disorders but that more research is needed to clarify relevant contexts and for whom the intervention is likely to be effective, (b) additional research should examine the effects of the high-p sequence on feeding in older children or adults with disabilities as more intrusive procedures based on escape extinction become inappropriate, and (c) the evidence falls short of meeting the CEC standards for an evidence-based practice. We conclude with preliminary practice guidelines.

The present study examined whether cognitive restructuring (CR) or mindfulness led to increases in decentering and whether changes in decentering were related to changes in anxiety and willingness to approach anxiety-provoking situations. Forty-six individuals with social anxiety completed speaking tasks before and after receiving CR, mindfulness, or control instructions. Overall, anxiety decreased and willingness increased from the first to second speech, with no differences across conditions. Decentering (measured by the Toronto Mindfulness Scale [TMS]) increased, with those in the mindfulness condition reporting more decentering. There was a nonsignificant, medium-sized effect on decentering, as measured by the Experiences Questionnaire (EQ)–Decentering factor, with those in CR reporting more decentering. Increases in decentering were associated with changes in self-reported anxiety and willingness. Findings indicate that mindfulness and CR led to changes in decentering, and that changes in decentering were related to changes in some, but not all, measures of anxiety.

Evaluating how, for whom, and under what conditions psychosocial treatments work is an important component of anxiety disorder treatment development. Yet, research regarding mediators and moderators of self-help interventions is sparse. The current project is a secondary analysis of mediators, moderators, and correlates of outcome of a randomized wait-list-controlled trial assessing acceptance and commitment therapy (ACT) self-help bibliotherapy for anxiety and related problems. Participants (n = 503) were randomized to an immediate workbook (n = 256) or wait-list condition (n = 247). Nonparametric bootstrapped mediation analyses showed that pre–post positive changes in ACT treatment processes accounted for the relation between treatment and pre–post improvement on the primary outcomes of anxiety symptoms, depressive symptoms, and quality of life. Results indicated no baseline variables were significant moderators. Finally, hierarchical regression analyses indicated that the degree of improvement for each primary outcome was positively correlated with the degree to which participants reported applying the workbook material to their day-to-day life, over and above how much of the book they reported reading. This study provided support for the ACT model of change in a self-help context and highlighted the importance of actively applying self-help material, addressing theoretical and practical questions about how and why ACT self-help works.
