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 treatment for their children's problem behavior. Seventeen caregivers of children with a developmental disability who displayed problem behaviors completed assessments in two conditions: a monetary reward paradigm and a paradigm related to treatment outcomes. Fifteen of 17 participants displayed patterns of choice-making suggesting discounting of delayed treatment outcomes. If corroborated in larger samples, our methods could afford clinicians a way to optimize their approach to caregivers to maximize the benefits of treatment.
