Functional analysis of hair manipulation: a replication and extension

In a multi‐phase investigation, we assessed the problematic hair manipulation of a four‐year‐old male diagnosed with autism. In phase 1, a functional analysis of hair manipulation resulted in high levels of responding during a no‐interaction condition, while near‐zero levels were observed in other conditions. In phase 2, hair manipulation was reduced to near‐zero levels during a condition in which Billy wore gloves on his hands to attenuate digital‐tactile stimulation. In phase 3, a stimulus preference assessment indicated that object manipulation competed with hair manipulation, and that wearing gloves did not alter the amount of time that Billy manipulated preferred objects. The results are discussed in the context of interventions that achieve their effects via reinforcer substitutability or competition. Copyright © 2000 John Wiley & Sons, Ltd.     

Spoon distance fading with and without escape extinction as treatment for food refusal

Little is known about the characteristics of meals that serve as motivating operations (MOs) for escape behavior. In the current investigation, we showed that the distance at which a therapist held a spoon from a child's lips served as an MO for escape behavior. Based on these results, we implemented spoon distance fading, compared fading with and without escape extinction (EE), and compared fading plus EE to EE alone. Initially, inappropriate mealtime behavior decreased during fading, but this effect was not maintained as fading progressed. Inappropriate mealtime behavior was lower initially when we combined fading and EE relative to EE alone, but acceptance increased more rapidly with EE than with fading plus EE. These results suggest that a number of mealtime characteristics might function as MOs for escape behavior and that analyses of MOs may be useful for developing treatments for food refusal.     

Integrating Exposure and Response Prevention With a Mobile App to Treat Obsessive-Compulsive Disorder: Feasibility,Acceptability, and Preliminary Effects

Many individuals with obsessive-compulsive disorder (OCD) do not receive evidence-based care (specifically exposure and ritual prevention; EX/RP) due to barriers such as a lack of EX/RP-trained clinicians, geographic obstacles, and the cost and time associated with the treatment. Offering an integrated treatment model consisting of brief in-person therapy coupled with a mobile application (app) might be one way to increase access to and reduce the time burden (to clinicians and patients) of EX/RP. This pilot trial evaluated the feasibility, acceptability, and clinical effects of such a treatment program for adults with OCD. Thirty-three participants enrolled in the 8-week open trial. The integrated treatment program consisted of 3 to 5 in-person sessions followed by weekly phone calls supported by a mobile app (nOCD). Participants were evaluated by trained raters and completed self-report measures at baseline, midtreatment, posttreatment and 2-month follow-up; the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was the primary outcome. This integrated treatment program was feasible and acceptable to participants. Of the 33 study entrants, 14 (42%) responded to treatment (Y-BOCS decrease ≥ 35% with CGI- of 1 or 2), and 8 (24%) achieved minimal symptoms (i.e., Y-BOCS ≤ 12). At 2-month follow-up (n = 20), 7/20 (35%) met criteria for treatment response, and 3/20 (15.0%) met criteria for treatment remission. Although preliminary, this model warrants further study as an efficacious and resource-efficient way to deliver EX/RP for some patients with OCD.     

The Effects of Animal-Assisted Activities on College Students Before and After a Final Exam

Final exams at colleges and universities have proven to be a time of anxiety and stress for students. This paper contains an exploration the effects of Animal-Assisted Activities (AAA) on exam anxiety through the use of blood pressure readings before and after interacting with therapy dogs. A comparison of the experimental and control groups interacting with therapy dogs has shown statistical significance for the reduction of blood pressure for those students who will or have taken a final exam. Having owned a pet, as well, as the age of the participant were not significant predictors of whether or not therapy dogs would reduce blood pressure.
