How should habit reversal training be implemented for a teenager with a tic disorder who is already receiving medication for attention‑deficit/hyperactivity disorder?

Habit Reversal Training for Teenagers with Tic Disorder and ADHD

Habit reversal training (HRT) is a highly effective behavioral intervention for tic disorders that should be implemented as first-line treatment for the tics, while continuing ADHD medication, with the understanding that treating ADHD symptoms first may improve adherence to the tic-focused behavioral therapy.

What is Habit Reversal Training?

HRT is a structured behavioral technique specifically designed to reduce tic frequency and severity. The intervention works by:

• Awareness training: Teaching the teenager to recognize the premonitory urge (the uncomfortable sensation that precedes a tic) and identify when and where tics occur
• Competing response training: Developing a physically incompatible movement or behavior that the patient performs when they feel the urge to tic
• Motivation and social support: Engaging family members to reinforce tic-suppressing behaviors
• Functional analysis: Identifying environmental triggers and situations that worsen tics

The technique has demonstrated medium to large effect sizes comparable to antipsychotic medications 1, with evidence showing it effectively decreases tic severity in children and adolescents 2.

Implementation Strategy for Your Patient

Step 1: Continue ADHD Medication

Your teenager should remain on their current ADHD medication. Stimulants do not worsen tics and are the recommended first-line pharmacotherapy for ADHD in patients with tic disorders 3. The ADHD medication actually facilitates better engagement with behavioral therapy 4.

Step 2: Prioritize ADHD Symptom Control First

Clinical experience suggests that treating ADHD symptoms before focusing intensively on tics improves outcomes 4. Why? Because:

• Better attention and impulse control enhance adherence to the HRT protocol
• ADHD symptoms often interfere with the sustained effort required for habit reversal
• Reduced hyperactivity allows for better awareness of premonitory urges

Step 3: Initiate HRT with Key Requirements

For HRT to succeed, ensure these elements are present:

• A cooperative patient who is motivated to reduce tics
• Presence of premonitory urges (the uncomfortable sensations before tics occur)
• Committed family involvement for reinforcement and support 5

The intervention typically involves 8-10 therapy sessions 1, though more therapeutic contact correlates with larger treatment effects.

Step 4: Address the Adherence Challenge

The most significant obstacle in treating tics behaviorally in teenagers with ADHD is maintaining adherence to the HRT procedure in daily life 4. To overcome this:

• Schedule HRT sessions when ADHD medication is active
• Use external reminders and cues for practicing competing responses
• Implement a reward system for consistent practice
• Involve parents in monitoring and reinforcing the competing response
• Start with the most bothersome or noticeable tic rather than trying to address all tics simultaneously

Evidence Quality and Nuances

The evidence base for HRT is robust. A meta-analysis of 8 randomized controlled trials with 438 participants demonstrated that patients receiving behavioral therapy were significantly more likely to show treatment response compared to controls, with a number needed to treat of 3 1. This means for every 3 patients treated with HRT, one additional patient responds compared to no treatment.

Important caveat: The meta-analysis found that co-occurring ADHD moderates treatment effects—meaning patients with ADHD may have slightly smaller improvements from HRT alone 1. This reinforces the importance of optimizing ADHD treatment first.

When to Consider Medication Adjustments

If tics remain severely impairing despite HRT and optimized ADHD treatment:

• Alpha-agonists (guanfacine or clonidine) can be added to stimulants, as they target both ADHD and tics 3
• Atomoxetine is an excellent alternative that treats both conditions 3
• These options are preferable to antipsychotics as initial add-on therapy

Common Pitfalls to Avoid

1. Don't stop ADHD medication due to tic concerns: Stimulants are safe and recommended in tic disorders 3
2. Don't attempt HRT before ADHD is controlled: Poor attention undermines the behavioral intervention 4
3. Don't expect immediate results: HRT requires consistent practice over weeks to months
4. Don't overlook the need for family involvement: Parental support is essential for success 5
