Pilot Testing Behavior Therapy for Chronic Tic Disorders in Neurology and Developmental Pediatrics Clinics

Comprehensive Behavioral Intervention for Tics (CBIT) is an efficacious treatment with limited regional availability. As neurology and pediatric clinics are often the first point of therapeutic contact for individuals with tics, the present study assessed preliminary treatment response, acceptability, and feasibility of an abbreviated version, modified for child neurology and developmental pediatrics clinics. Fourteen youth (9-17) with Tourette disorder across 2 child neurology clinics and one developmental pediatrics clinic participated in a small case series. Clinician-rated tic severity (Yale Global Tic Severity Scale) decreased from pre- to posttreatment, z = –2.0, P \u3c .05, r = –.48, as did tic-related impairment, z = –2.4, P \u3c .05, r = –.57. Five of the 9 completers (56%) were classified as treatment responders. Satisfaction ratings were high, and therapeutic alliance ratings were moderately high. Results provide guidance for refinement of this modified CBIT protocol

Suicidal Thoughts and Behaviors in Children and Adolescents With Chronic Tic Disorders

Objective: Despite evidence of elevated risk factors for suicidal thoughts and behavior in youth with Tourette syndrome and chronic tic disorders (CTD), few studies have actually examined that relationship. This study documented the frequency and clinical correlates of suicidal thoughts and behaviors in a sample of children and adolescents with CTD (N = 196, range 6–18 years old). The content is solely the responsibility of the authors and does not necessarily represent the official views of the Centers for Disease Control. Method: Youth and parents completed a battery of measures that assessed co-occurring psychiatric diagnoses, child emotional and behavioral symptoms, and impairment due to tics or co-occurring conditions. Results: A structured diagnostic interview identified that 19 youths with CTD (9.7%) experienced suicidal thoughts and/or behaviors, which was elevated compared to 3 youths (3%) who experienced these thoughts in a community control sample (N = 100, range 6–18 years old, P = .03). For youth with CTD, suicidal thoughts and behaviors were frequently endorsed in the context of anger and frustration. The Child Behavior Checklist (CBCL) anxious/depressed, withdrawn, social problems, thought problems, and aggressive behavior subscales, as well as the total internalizing problems scale, were associated with the presence of suicidal thoughts and/or behaviors. Suicidal thoughts and/or behaviors were significantly associated with tic symptom severity; tic-related impairment; and obsessive–compulsive, depressive, anxiety, and attention-deficit/hyperactivity disorders’ symptom severity. CBCL anxiety/depression scores mediated the relationship between tic severity and suicidal thoughts and behaviors. Conclusions: Findings suggest that about 1 in 10 youth with CTD experience suicidal thoughts and/or behaviors, which are associated with a more complex clinical presentation and often occur in the presence of anger and frustration

Utility of the Diagnostic Interview Schedule for Children for Assessing Tourette Syndrome in Children

Objective: The Diagnostic Interview Schedule for Children IV (DISC) has been used extensively in research and screening. Despite wide use, little information exists on the validity of the DISC for diagnosing tic disorders. Methods: Participants were 181 youth with expert clinician-diagnosed Tourette syndrome (TS). Results: Using expert clinician-diagnosed TS as the gold standard, the sensitivity of the DISC-Y (youth, 0.27) and DISC-P (parent, 0.44) was poor. The DISC-Y identified 29.7% of youth with diagnosed TS whereas the DISC-P identified 47.4% of cases. Only 54% of cases of TS were detected by either the DISC-Y or -P. Diagnostic agreement between the DISC and expert clinician diagnosis was poor. The DISC-Y/P results did not differ as a function of tic severity. Conclusions: Despite utility for assessing child psychiatric disorders, the sensitivity of the DISC for detecting TS appears poor. This study suggests that DISC has low agreement with expert clinician diagnosis of TS. Findings highlight the need for modification of the DISC and/or the identification and development of more sensitive measures for TS screening
