Increasing social time allocation and concomitant effects on mands, item engagement, and rigid or repetitive behavior

Recent research has developed methods of assessing the function of generic, nonindividualized social interactions. The purpose of this type of assessment is to provide a measure of how an individual may respond to the types of interactions readily available in the natural environment. To date, no research has evaluated how the social time allocation of individuals for whom generic interactions are neutral or aversive could be improved. Moreover, no research has included additional dependent variables that may be functionally related to social time allocation. In the current study, we evaluated the effects of initiating preferred, individualized social interactions on the social time allocation of 3 participants for whom generic interactions functioned as neutral or aversive stimuli. The intervention increased social time allocation for all 3 participants. Next, we evaluated the relation between social time allocation and the occurrence of mands, item engagement, and rigid or repetitive behavior using the intervention data as well as secondary analyses of previously published datasets. The occurrence of mands and rigid or repetitive behaviors changed with improvements in social time allocation and were strongly correlated with social time allocation across participants. Implications for future research on, and the clinical use of, this type of assessment and intervention are discussed.
