Describing demographic variables (e.g., ethnicity/race, socioeconomic status, gender/sex, age) of participants may be important for identifying relations between these variables and behavior‐analytic procedures. Previous research found that demographic variables were underreported in behavior‐analytic studies dealing with particular populations (e.g., children with Autism Spectrum Disorder), interventions (e.g., verbal behavior), or for a subset of demographic variables. We evaluated the extent to which studies recently published in the Journal of Applied Behavior Analysis included descriptions of demographic variables of participants. Demographic variables were often underreported, which may limit the broader dissemination of these behavior‐analytic studies and the development of culturally responsive modifications to behavioral interventions.

Pica is a life threating form of challenging behavior displayed by individuals with intellectual and developmental disabilities. In most cases, pica is maintained by automatic reinforcement. Common interventions for pica use some combination of response blocking, response interruption and redirection (RIRD), differential reinforcement of alternative behavior (DRA), and noncontingent reinforcement with competing stimuli. However, there is need for additional research regarding DRA procedures that emphasize skills acquisition by teaching alternative behaviors that modify the established behavioral chain of pica responses that occur in the presence of non-edible stimuli. There is also a need to examine the generality of recent advances in competing stimulus assessment (CSA) methodologies-namely, the augmented-CSA (A-CSA)-to pica. Thus, the purpose of the present investigation was to systematically replicate and extend previous research for the assessment and treatment of pica in an individual with IDD. First, we conducted a functional analysis to identify environmental variables associated with pica. Next, taught Patrick a differential response (i.e., discard pica items in trash receptacle) to earn reinforcers in conjunction with a RIRD procedure. Finally, we conducted an A-CSA for pica. Overall, low rates of pica were maintained over time with a combination of these procedures, and treatment was generalized across settings and people.
