Brief summary

This study will test the efficiency of the Freespira Breathing System in youth.

Detailed description

The Freespira Breathing System (FBS; www.freespira.com) developed by Palo Alto Health Sciences, Inc, is a portable home device , and has been employed in breathing biofeedback in adults with panic disorder (PD). The FBS has now received FDA clearance for the treatment of PD adults and is currently commercially available and more than 150 therapist have provided the service nationally. However, FBS has not yet been tested for efficacy in a pediatric populations. Due to its portability, FBS may pose an advantage for use in younger age groups, compared to multiple therapy sessions required for cognitive behavioral therapy (CBT) or lower acceptability for long-term medication use for adolescent PD. In this pilot intervention study, the efficacy of the FBS system in youth will be tested. In children adolescents, PD itself is less common than in adults, but when present, PD is commonly associated with and/or preceded by other anxiety conditions, including generalized anxiety disorder (GAD), social phobia (SoP) and separation anxiety (SAD). Thus, in children and adolescents, the breathing biofeedback intervention for panic, should include other anxiety disorders.

Interventions

Over an 8-week period the efficacy of the FBS system in youth will be tested, with those in the randomized active device group. The control group will not receive the device until completion of the 8 week baseline.

Design outcomes

Primary

MeasureTime frameDescription
Screen for Child Anxiety Related Disorders (SCARED) scale score8-weeksThe Screen for Child Anxiety Related Disorders (SCARED) is a 41-item inventory rated on a 3 point Likert-type scale. It comes in two versions; one asks questions to parents about their child and the other asks these same questions to the child directly. The purpose of the instrument is to screen for signs of anxiety disorders in children.

Panic Disorder Severity Scale for Adolescents (PDSS-A)BaselinePanic Disorder Severity Scale for Adolescents \[PDSS-A\] seven question scale referring to panic attacks and symptoms during each episode and how severe the attacks were. Each question is given a rating from 0-4 and the total score from each of the seven questions becomes the score used to assess severity. The higher the score the more severe the panic disorder.
Clinician's Global Impression scale.BaselineClinician's Global Impression (CGI) scale is a three item observer rated scale that measures illness severity, global improvement or change, and therapeutic response. It is rated on a seven point scale with the severity of illness scale using a range of responses from one (normal) to seven (around the most severely ill patients). Each component of the CGI is rated separately; the instrument does not yield a global score. This will serve as the measure of overall improvement in the patients symptoms because of the FBS treatment.

Child Yale Brown Obsessive-Compulsive Scale scoreBaselineChild Yale Brown Obsessive-Compulsive Scale is a measure of obsessive compulsion disorder symptoms. This scale is designed to rate the severity of obsessive and compulsive symptoms in children from 6-17 years. In general the ratings depend on the child's and parents report; however the final rating is based on the clinical judgement of the interviewer. The characteristics of each item over the prior week up until; and including, the time of the interview are rated. The child's symptoms are scored using the compulsions checklist and the obsessions checklist as guides. All 19 items are rated but only items 1-10 are used to determine the final score. The total score is the sum of items 1-10; the obsession and compulsion subtotals are the sums of items 1-5 and 6-10, respectively. This will be measured through out the study to see the effectiveness of the treatment.
