Integrating Exposure and Response Prevention and Habit Reversal Techniques to Treat a Tourettic Subtype of Obsessive-Compulsive Disorder (Tourettic OCD) (TORCH)

23. Juli 2026 aktualisiert von: Dipesh Patel, University College London Hospitals
Obsessive-Compulsive Disorder and Tic Disorders frequently co-occur, and a subgroup of patients - those with a Tourettic Subtype of OCD (TOCD) - present with concurrent obsessive-compulsive and tic symptoms. Existing psychological interventions typically target one condition or the other, but rarely both together. This study aims to test whether a combined psychological therapy integrating Exposure and Response Prevention (ERP) and Habit Reversal (HbRT) is more effective at reducing symptoms than either therapy delivered alone, in adults with TOCD.

Detaillierte Beschreibung

Participants are randomly allocated to one of four groups: (1) combined ERP and HbRT, (2) ERP alone, (3) HbRT alone, or (4) a supportive psychoeducation control. All participants receive 12 weekly one-to-one sessions (either in-person or remotely) of approximately fifty minutes. Symptoms will be assessed using the Yale Global Tic Severity Scale (YGTSS) and Yale-Brown Obsessive Compulsive Scale (Y-BOCS) by an independent clinician at the start of treatment, at Week 12, and again at Week 24.

Waffen und Interventionen

Teilnehmergruppe / Arm
Intervention / Behandlung
Experimental: Combined Exposure and Response Prevention and Habit Reversal
Participants allocated to this arm will receive a 12-week individual psychological intervention integrating Exposure and Response Prevention (ERP) and Habit Reversal Training (HRT). ERP will involve planned exposure to obsessional fears, distress, sensory discomfort, premonitory urges, and "not-just-right" experiences while reducing compulsions, avoidance, reassurance seeking, and other safety behaviours. HRT will include awareness training, identification of premonitory urges and tic-related cues, development and practice of competing responses, and strategies to support generalisation. Sessions will last approximately 50 minutes and will be delivered face-to-face or remotely.
Exposure and Response Prevention (ERP) is a behavioural intervention that involves gradual and systematic exposure to obsessional fears, distress, sensory discomfort, premonitory urges, and "not-just-right" experiences while refraining from compulsions, avoidance, reassurance seeking, and other safety behaviours. Treatment is delivered individually over 12 weekly 50-minute sessions, either face-to-face or remotely.
Habit Reversal Training (HbRT) is a behavioural intervention that includes awareness training, identification of premonitory urges and antecedents to tic expression, development and practice of competing responses, and strategies to generalise skills across settings. Treatment is delivered individually over 12 weekly 50-minute sessions, either face-to-face or remotely.
Aktiver Komparator: Psychoeducation / Supportive Intervention
Participants allocated to this arm will receive a 12-week individual psychological intervention consisting of psychoeducation and supportive therapy. Sessions will provide information about obsessive-compulsive disorder, tic disorders, Tourettic obsessive-compulsive disorder, stress, and wellbeing, together with supportive discussion and general problem-solving. This intervention will not include structured Exposure and Response Prevention, Habit Reversal Training, or other targeted behavioural techniques. Sessions will last approximately 50 minutes and will be delivered face-to-face or remotely.
Psychoeducation and Supportive Therapy consists of structured education about obsessive-compulsive disorder, tic disorders, Tourettic obsessive-compulsive disorder, stress, and wellbeing, together with supportive discussion and general problem-solving. The intervention does not include Exposure and Response Prevention, Habit Reversal Training, or other targeted behavioural techniques. Treatment is delivered individually over 12 weekly 50-minute sessions, either face-to-face or remotely.
Aktiver Komparator: Standardised Exposure and Response Prevention
Participants allocated to this arm will receive a 12-week individual psychological intervention based on Exposure and Response Prevention (ERP). Treatment will involve gradual and systematic exposure to obsessional fears, distress, sensory discomfort, premonitory urges, and "not-just-right" experiences while refraining from compulsions, avoidance, reassurance seeking, and other safety behaviours. The intervention aims to reduce obsessive-compulsive symptoms by promoting inhibitory learning and increasing tolerance of uncertainty and internal experiences. Sessions will last approximately 50 minutes and will be delivered face-to-face or remotely.

Aktiver Komparator: Standardised Habit Reversal
Participants allocated to this arm will receive a 12-week individual psychological intervention based on Habit Reversal Training (HbRT). Treatment will include awareness training to improve recognition of tics and premonitory urges, identification of antecedents and contextual triggers, development and practice of competing responses, and strategies to promote generalisation of skills to everyday settings. The intervention aims to reduce tic severity and improve voluntary tic management. Sessions will last approximately 50 minutes and will be delivered face-to-face or remotely.

Zeitfenster
Change From Baseline in Yale Global Tic Severity Scale Global Severity Score
Zeitfenster: Baseline, Week 12 and Week 24
Overall tic symptom severity and tic-related impairment will be assessed using the Yale Global Tic Severity Scale (YGTSS) Total Score. The Global Score is calculated by summing the Total Tic Severity Score (0-50) and the Impairment Score (0-50), resulting in a global score ranging from 0 to 100. Higher scores indicate greater overall tic severity and impairment. Change from baseline will be assessed at Week 12 and Week 24.
