This chapter describes the treatment of tic disorders in psychosis, where severe tics and poor insight may present with overlapping phenomenology to psychotic symptoms. It starts by clarifying treatment goals and outlines assessment using the Yale Global Tic Severity Scale to evaluate motor tics, vocal tics, overall severity, and impairment. The intervention module combines Exposure and Response Prevention with Habit Reversal Training, explaining how exposure to tic triggers, prevention of tic responses, and the use of competing responses can reduce tic frequency and distress. The chapter frames tic treatment as a way to reduce functional interference and to clarify the boundary between tic-related phenomena and true psychotic symptoms.
