Homework adherence between behavior therapy sessions is a significant predictor of therapeutic improvement in patients with Tourette’s disorder (TD), a study of 119 youth and adults suggests.
The assigning of “homework” to be completed between sessions – often used in cognitive-behavioral therapy – has been shown to reinforce learning but has not been well studied in TD.
“Understanding the relationship between homework adherence and therapeutic improvement from behavior therapy for TD may offer new insights for enhancing tic severity reductions achieved during this evidence-based treatment,” wrote Joey Ka-Yee Essoe, PhD, of the department of psychiatry and behavioral sciences at Johns Hopkins University, Baltimore, and colleagues.
To conduct the study, published in Behaviour Research and Therapy, the researchers recruited 70 youth and 49 adults with TD, ranging in age from 9 to 67 years, who underwent treatment at a single center. The average age was 21 years, and 80 participants were male. Treatment response was based on the Clinical Global Impressions of Improvement scale (CGI-I). Participants were assessed at baseline for tic severity and received eight sessions over 10 weeks. During those sessions, they were taught to perform a competing response to inhibit the expression of a tic when the tic or urge was detected.
Participants received homework at each weekly therapy session; most consisted of three to four practice sessions of about 30 minutes per week. Therapists reviewed the homework at the following session and adapted as needed to improve tic reduction skills.
After eight sessions of behavior therapy, overall greater homework adherence significantly predicted reduced tic severity and therapeutic improvement. However, early homework adherence predicted therapeutic improvement in youth, while late homework adherence predicted it in adults.
Overall,
However, homework adherence dipped midway through treatment in youth and showed a linear decline in adults, the researchers noted.
Among youth, baseline predictors of early homework adherence included lower levels of hyperactivity/impulsivity and caregiver strain. Among adults, baseline predictors of early homework adherence included lower anger scores, less social disability, and greater work disability.
The study findings were limited by several factors, including the absence of complete data on baseline predictors of homework adherence, reliance on a single measure of tic severity and improvement, and reliance on therapists’ reports of homework adherence, the researchers noted.
Future research should include objective measures of homework adherence, such as time-stamped videos, and different strategies may be needed for youth vs. adults, they added.
“Strategies that optimize homework adherence may enhance the efficacy of behavioral therapy, lead to greater tic severity reductions, and higher treatment response rates,” Dr. Essoe and colleagues wrote.
The study was supported by the Tourette Association of America, the National Institute of Mental Health, the American Academy of Neurology, and the American Psychological Foundation.
