Call, Nathan A.; Alvarez, Jessica P.; Simmons, Christina A.; Lomas Mevers, Joanna E.; Scheithauer, Mindy C. – Autism: The International Journal of Research and Practice, 2017
The external validity of behavioral treatments for elopement (i.e. leaving supervision without permission) remains unclear because studies to date include only small samples (n = 1-3). This study quantified the overall effectiveness of behavioral treatments for elopement by retrospectively examining treatment data from all patients seen for the…

Call, Nathan A.; Reavis, Andrea R.; McCracken, Courtney E.; Gillespie, Scott E.; Scheithauer, Mindy C. – Journal of Autism and Developmental Disorders, 2015
Parent engagement in behavioral interventions is critical for treatments to succeed. Parental decision-making regarding treatments can be impacted by systematic biases, such as the tendency to discount the value of delayed benefits, or "delay discounting". This study examined the impact of delay discounting on parents' perceptions of…

Call, Nathan A.; Simmons, Christina A.; Mevers, Joanna E.; Alvarez, Jessica P. – Journal of Autism and Developmental Disorders, 2015
Pica is a potentially deadly form of self-injurious behavior most frequently exhibited by individuals with developmental and intellectual disabilities. Research indicates that pica can be decreased with behavioral interventions; however, the existing literature reflects treatment effects for small samples (n = 1-4) and the overall success of such…

Volkert, Valerie M.; Lerman, Dorothea C.; Call, Nathan A.; Trosclair-Lasserre, Nicole – Journal of Applied Behavior Analysis, 2009
Extinction-induced resurgence is the recurrence of previously reinforced behavior when another behavior is placed on extinction (Lieving, Hagopian, Long, & O'Connor, 2004). This phenomenon may account for some instances of treatment relapse when problem behavior recovers during extinction-based treatments. The current study sought to determine…

Asmus, Jennifer M.; Ringdahl, Joel E.; Sellers, Jennifer A.; Call, Nathan A.; Andelman, Marc S.; Wacker, David P. – Journal of Applied Behavior Analysis, 2004
Previous outcome studies have provided descriptions of functional analyses conducted in outpatient clinics (Derby et al., 1992), long-term inpatient programs (Iwata, Pace, et al., 1994), and home environments (Wacker et al., 1998). This study provides a description of 138 children and adults with and without developmental disabilities who were…

Roane, Henry S.; Call, Nathan A.; Falcomata, Terry S. – Journal of Applied Behavior Analysis, 2005
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…
