A Stakeholder-Engaged Approach to Development of an Animal-Assisted Intervention for Obesity Prevention Among Youth With Autism Spectrum Disorder and Their Pet Dogs.

Stakeholder involvement in research has been demonstrated to increase the effectiveness, validity, and quality of a study. This paper describes the engagement of a stakeholder panel in the development and implementation of an animal-assisted intervention (AAI) assessment and program for children diagnosed with Autism Spectrum Disorder (ASD). Canines for Autism Activity and Nutrition (CAAN) aims to promote physical activity and wellness among children diagnosed with ASD by integrating activities with their pet dog during the child's ongoing Applied Behavioral Analysis (ABA) in-home therapy sessions. Feedback from stakeholders guided program development at each stage of the research process, including this publication. Utilizing a stakeholder-informed approach was essential for the development of assessment tools, program materials, and program design. Methods that may assist others to effectively partner with stakeholders to implement an AAI among children diagnosed with ASD or related disorders are described.

An analysis of treatment integrity of response interruption and redirection.

Response interruption and redirection has been shown to effectively decrease stereotypy, but its application outside an experimental setting has not been well studied. In Experiment 1, decreases in automatically maintained vocal stereotypy were obtained following treatment in a controlled setting for 3 participants diagnosed with autism spectrum disorder. Descriptive data on the consistency and accuracy of response interruption and redirection were then collected in the classroom setting. Results showed that the consistency of treatment implementation varied across participants and staff members. Failure to implement the treatment was the most common error. However, when response interruption and redirection was implemented, the components were generally carried out as prescribed. In Experiment 2, we conducted a parametric analysis in a controlled setting to test the impact of consistency errors on response interruption and redirection. The results indicated that response interruption and redirection was generally effective at 50% treatment implementation or higher. Furthermore, we observed treatment effects when 25% implementation sessions were interspersed with 100% treatment implementation sessions. Application of response interruption and redirection in light of previous studies and clinical implications are discussed.

Neuropsychological performance in treatment-seeking Operation Enduring Freedom/Operation Iraqi Freedom Veterans with a history of mild traumatic brain injury.

INTRODUCTION: Clinical neuropsychological presentation of treatment-seeking Veterans with a remote history of mild traumatic brain injury (mTBI) is widely variable. This manuscript seeks to better characterize cognitive concerns in the post-acute phase following mTBI and to identify the neuropsychological profiles of a large sample of clinically referred Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) Veterans with a history of mTBI and current cognitive complaints. We hypothesized that a minority of cases would exhibit valid and widespread neuropsychological deficits. METHOD: Retrospective chart reviews of neuropsychological testing and mental health symptoms and diagnoses were conducted on 411 clinically referred OEF/OIF/OND Veterans with a history of mTBI. Groups were created based on scores on performance validity measures and based on overall neuropsychological performance. RESULTS: A total of 29.9% of the sample performed below normative expectations on at least one performance validity test (PVT). Of those Veterans performing adequately on PVTs, 60% performed within normal limits on virtually all neuropsychological measures administered, leaving only 40% performing below expectations on two or more measures. Mood and neurobehavioral symptoms were significantly elevated in Veterans performing below cutoff on PVTs compared to Veterans who performed within normative expectations or those with valid deficits. Neurobehavioral symptoms were significantly correlated with mental health symptom reports but not with injury variables. CONCLUSIONS: In summary, in a large sample of clinically referred Veterans with persistent cognitive complaints after mild TBI, a third demonstrated invalid clinical neuropsychological testing, and, of those performing at or above cutoff on PVTs, over half performed within normative expectations across most neuropsychological tests administered. Results highlight the importance of objective assessment of cognitive functioning in this population as subjective reports do not correspond to objective assessment in the majority of cases.

The effects of verbal operant training and response interruption and redirection on appropriate and inappropriate vocalizations.

Past research has shown that response interruption and redirection (RIRD) can effectively decrease automatically reinforced motor behavior (Hagopian & Adelinis, 2001). Ahearn, Clark, MacDonald, and Chung (2007) found that a procedural adaptation of RIRD reduced vocal stereotypy and increased appropriate vocalizations for some children, although appropriate vocalizations were not targeted directly. The purpose of the current study was to examine the effects of directly targeting appropriate language (i.e., verbal operant training) on vocal stereotypy and appropriate speech in 3 children with an autism spectrum disorder. The effects of verbal operant (i.e., tact) training were evaluated in a nonconcurrent multiple baseline design across participants. In addition, RIRD was implemented with 2 of the 3 participants to further decrease levels of vocal stereotypy. Verbal operant training alone produced slightly lower levels of stereotypy and increased appropriate vocalizations for all 3 participants; however, RIRD was required to produce acceptably low levels of stereotypy for 2 of the 3 participants.
