Computerized Cognitive Behavioral Therapy for Childhood Anxiety in Community Health Centers

Study Overview
=================
Brief Summary
-----------------
This study will examine the efficacy of a computerized cognitive behavioral therapy (CCBT) program for children with anxiety disorders in community health centers. The first phase of the study will offer insight into the feasibility of providing this intervention in community health centers, while the second phase will compare CCBT to treatment as usual.

Detailed Description
-----------------
Childhood anxiety disorders are quite common and associated with significant psychosocial impairment and distress. Offering equivalent efficacy to pharmacotherapy without the common side effect profile, cognitive behavioral therapy (CBT) is a first line treatment for anxiety disorders in youth. However, dissemination of CBT to community settings is very limited. Effective treatment via traditional CBT often necessitates that the patient travel to a center that specializes in this treatment, and cost can prove an impediment to those of lower socioeconomic status, in particular. As well, differing theoretical approaches and training result in a minority of children with anxiety receiving evidence-based CBT. Accordingly, there is a great need for more widely accessible practices. As such, we are proposing a two phase trial that evaluates the feasibility of implementing a patient-centered intervention in community mental health centers, followed by an efficacy trial. In Phase I, an open trial of computerized CBT (CCBT) will be completed that focuses on feasibility issues of providing this intervention in community mental health centers. Thereafter, we will complete a randomized controlled trial comparing CCBT to treatment as usual (TAU) in Phase II. The open trial will recruit 18 youth ages 7 to 13 years, with the purpose of testing both practicality and management of an already developed CCBT protocol (Kendall & Khanna, 2008). The outcome trial will recruit 110 youth, with the purpose of measuring the efficacy of the CCBT protocol in front-line settings. Significantly greater symptom reductions in the CCBT group as compared to the TAU group would provide critical evidence for the inclusion of CCBT as a treatment option for anxious youth without immediate access to such in-person care. While this study will be coordinated by the University of South Florida Rothman Center for Neuropsychiatry team who is located at All Children's Hospital (USF/ACH), recruitment will take place at three community mental health centers throughout Florida that serve families of lower socioeconomic status. Primary outcomes will be assessed by an independent evaluator, and will include change in anxiety symptom severity; response rates; and remission rates. CCBT will follow the Kendall and Khanna (2008) manual with appropriate integrity checks. The implications of this study are significant, as computerized CBT may enable widespread dissemination of efficacious therapy for anxiety disorders among youth.

Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Outpatient boys and girls with an anxiety disorder (see below) aged 7-13 years. Meets DSM-IV criteria for a diagnosis of one of the following anxiety disorders: separation anxiety disorder (SAD), generalized anxiety disorder (GAD), or social phobia. Minimum score of 14 on the PARS Severity Scale. The child has a Full Scale IQ greater than 80 as assessed on the Wechsler Abbreviated Scale of Intelligence. Have home access to a computer with internet connection. Exclusion Criteria: Receiving concurrent psychotherapy or other counseling services. New Treatments: Initiation of an antidepressant within 12 weeks before study enrollment or an antipsychotic 6 weeks before study enrollment. No new alternative medications, nutritionals or therapeutic diets within 6 weeks of study enrollment. However, pharmacological interventions may be initiated or added if the child is randomized to the Treatment as Usual arm in Phase II. Established Treatment changes: Any change in established psychotropic medication (e.g., antidepressants, anxiolytics) within 8 weeks before study enrollment (6 weeks for antipsychotic). Alternative medications that might have behavioral effects must be stable for 6 weeks prior to the study baseline assessment. Any medications that the child is on must remain stable during treatment unless s/he is randomized to the Treatment as Usual arm in Phase II. (a) Current clinically significant suicidality or (b) individuals who have engaged in suicidal behaviors within 6 months. Lifetime DSM-IV bipolar disorder, schizophrenia, or schizoaffective disorder. Unwillingness of parents to make the commitment to accompany their children for study visits/assessments. Presence of a significant and/or unstable medical illness which might lead to hospitalization during the study.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Computerized Cognitive Behavioral Therapy<br> | Behavioral: Computerized Cognitive Behavioral Therapy<br>* Those who choose to participate will be enrolled in the 14 week study (18 weeks for phase II). They will required to attend 3 assessments - pre-treatment (week 0), mid-treatment (week 8), and post-treatment (week 14) (and a 4th assessment for a 1 month Follow-up for Phase II at week 18). This group will follow the CCBT protocol (Camp Cope-A-lot), which is the computer-assisted intervention for anxious children being examined in this study. The first 6 levels of this program are skill building levels to be completed by the user in his/her own home. The remaining 6 levels are completed with the therapist and consist of exposure tasks and rehearsal geared toward each child.<br>|
| Active Comparator: Treatment as Usual<br> | Behavioral: Treatment as usual<br>* Those who choose to participate will be enrolled in the 14 week study (18 weeks for phase II). They will required to attend 3 assessments - pre-treatment (week 0), mid-treatment (week 8), and post-treatment (week 14) (and a 4th assessment for a 1 month Follow-up for Phase II at week 18). Those in this group will not receive the CCBT, and instead will undergo therapy for their anxiety as they usually would, whether by using medication or working with a therapist.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| PARS | Pediatric Anxiety Rating Scale (PARS)- The PARS (RUPP, 2002) is a clinician-rated scale assessing anxiety symptoms and the associated severity and impairment in children over the past week. The scale score ranges from 0 to 30 with higher scores reflecting worse anxiety. The score, ranging from 0-30 represents a total score by summing all 6 items (which have item response options ranking from 0 to 5 each). | 14 Weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| ADIS-C/P Clinical Severity Rating | Anxiety Disorders Interview Schedule for DSM-IV: Child and Parent Versions (ADIS-IV-C/P)- The ADIS-IV-C/P (Silverman & Albano, 1996) is a clinician-administered, semi-structured interview that assesses for the presence and severity of DSM-IV anxiety disorders as well as Dysthymia and Major Depression, ADHD, Conduct Disorder, and Oppositional-Defiant Disorder. Excellent psychometric properties have been reported (e.g., Wood et al., 2002). The Clinical Severity Rating score is a one item metric reflecting the severity of the anxiety diagnosis. This is rated by the clinician based on their interview with the patient and parent, together with their judgment. The Rating ranges from 0 to 8 with higher scores reflecting worse anxiety. | 14 weeks |
