Acceptance and commitment therapy (ACT) is a function-based treatment that can be applied to multiple clinical concerns where psychological inflexibility is a mediating issue. This case study describes the use of ACT in combination with habit reversal training for a man with a primary concern of Tourette’s disorder and a secondary concern of chewing tobacco use. Large reductions were seen in the primary outcomes of motor and vocal tics (measured by behavioral tracking and a semi-structured assessment) and chewing tobacco use after 19 individual sessions. Furthermore, increases in psychological flexibility and quality of life and decreases in overall symptomatology were seen at posttreatment. This article conceptualizes this case from a cohesive theory, describes the details of the presenting concerns, and explains the treatment used and treatment outcomes. A description of barriers and suggestions for further treatment and research are also presented.
