Trial Outcomes & Findings for Effectiveness of Sertraline and Cognitive Behavioral Therapy in Treating Pediatric Obsessive-Compulsive Disorder (NCT NCT00382291)

NCT ID: NCT00382291

Last Updated: 2013-03-12

Results Overview

The CGI-SA was adapted from the Clinical Global Impressions - Severity of Illness (CGI-SI) rating (Guy, 1976). The CGI-SI is commonly used in clinical studies of children and adults and has been extensively validated (Zaider et al., 2003). On the CGI-SA clinicians rate the severity of activation symptoms on a range from 0 (no activation) to 7 (extremely severe symptoms, functionally highly impaired and/or extreme distress). We report values representing Median+/-Std Dev for the maximum CGI-SA obtained over the course of study.

Participant Flow

The study was performed at two child and adolescent psychiatric clinics within university medical centers: Gainesville, Florida (FL) (UF) and Tampa, FL (USF). Recruitment started in early 2009 and ended in late 2010.

Fifteen participants were excluded after screening: 7/15 did not meet inclusion/exclusion criteria and 8/15 withdrew consent.

Measure
Placebo Plus CBT
Placebo plus cognitive behavior therapy (CBT).
Regular Sertraline Titration Plus CBT
Regular titration of sertraline (RegSert) plus cognitive behavior therapy. The titration schedule used a flexible upward titration from 25 mg/day to 200 mg/day over 9 weeks unless higher doses were not tolerated, after which the dosage was adjusted as a function of tolerability. If tolerated, maximum dose could be achieved in 5 weeks.
Slow Sertraline Titration Plus CBT
Slow titration of sertraline (SloSert)plus cognitive behavior therapy. The titration schedule utilized a slower titration schedule relative to the RegSert arm. Unless unable to tolerate higher doses, children remained on 25mg/day for the first two weeks, 50mg/day from weeks 3-4, 75mg/day for weeks 5-6, 100mg/day for week 7, 150mg/day for week 8, and 200mg/day for week 9 until the end of the study.

PRIMARY outcome

Timeframe: Measured at Week 18 or End of Study

The CY-BOCS (Scahill et al., 1997) is a semi-structured, clinician rated instrument to measure OCD symptom severity in youth. The CY-BOCS contains a symptom checklist and a severity scale. Through the symptom checklist the clinician assesses current and past experiences of over 60 potential obsessions and compulsions. The Total Score represents the sum of obsession severity and compulsion severity which each consist of five clinician ratings on a Likert scale (range from 0 (none) to 4 (extreme), for time spent, interference, distress, resistance and control over symptoms). Summing of obsession and compulsion severity (range 0-20 on each) produces the Total CY-BOCS score (range 0-40, with 0 representing the best and 40 the worst outcome). Studies have documented good psychometric properties of the CY-BOCS (Gallant et al., 2008; Scahill et al., 1997; Storch et al., 2004).
