Abstract

The purpose of the current study was to examine an ACT based intervention and its effects on problem behaviors and impulsivity rates displayed by individuals diagnosed with Mild Intellectual Disabilities. In a multiple baseline design with 2 experiments, 6 participants completed the 27-item monetary choice questionnaire weekly throughout the 9-week study. Impulsivity rates were calculated, and behavior data was collected throughout each phase of the study. During the intervention phase of the study brief ACT sessions were conducted 3 times a week during one-on-one sessions with each participant. Sessions were held face-to-face or via phone call. A stacked multiple baseline design was computed, and the data was inputted, indicating that ACT may effectively reduce problem behaviors in participants diagnosed with Mild Intellectual Disabilities. The current study suggests that ACT interventions have no effect on impulsivity. Implications of the findings and future research are discussed. Keywords: ACT, Impulsivity, Delay Discounting, Intellectual Disability, Monetary Choice Questionnaire
