An interventional study of Freespira Breathing System in Anxiety and Panic Disorder, sponsored by Johns Hopkins University. Terminated at 1 site in United States. Open to participants aged 9 Years to 17 Years. Per ClinicalTrials.gov, last updated 2026-09-03.
Sponsored by Johns Hopkins University · Not applicable, Interventional, and Treatment
This study will test the efficiency of the Freespira Breathing System in youth.
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.
270 studies on the registry are indexed under Panic Disorder; 37 are open to participants now.
This study's planned enrollment of 73 is close to the median of 77 across 215 interventional studies indexed under Panic Disorder.

Device: Freespira Breathing System
The device will be given to those in the control group after 8-week baseline period.
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.

Panic Disorder Severity Scale for Adolescents (PDSS-A)
Panic 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.
Clinician'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 score
Child 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.

Child Sheehan Disability Scale (CSDS)
The CSDS was designed to measure the extent to which the child's anxiety symptoms were interfering with daily functioning. The CSDS is an adaptation of the Sheehan Disability Scale and consisted of items inquiring about the degree to which the child's anxiety symptoms interfere with school, social, and family functioning. As on the SDS, items are measured on an 11-point Likert-type scale ranging from 0 (not at all) to 10 (very, very much) .The wording of the anchors on the SDS was adapted to be more appropriate for children. A parent version (CSDS-P) that included six items was also created. The CSDS-P included three items that assessed the degree to which the parents perceived the child's anxiety symptoms to be interfering with the child's functioning (school, social, family) as well as three items that assessed the degree to which the child's symptoms were viewed as interfering with the parent's functioning (work, social, family).

Children's Depression Inventory ( CDI2)
The Children's Depression Inventory (CDI and CDI2) is a psychological assessment that rates the severity of symptoms related to depression or dysthymic disorder in children and adolescents. The CDI is a 27-item scale that is self-rated and symptom-oriented. The assessment is now in its second edition. The 27 items on the assessment are grouped into five major factor areas. Clients rate themselves based on how they feel and think, with each statement being identified with a rating from 0 to 2.

Childhood Anxiety Sensitivity Index (CASI)
The Child Anxiety Sensitivity Index is an 18-item scale which measures anxiety sensitivity by asking children to state how aversely they view anxiety symptoms. The child is to mark either "none" (I), "some" (2), or "A Lot" (3) to each item. The child's total anxiety sensitivity score is the sum of his or her points.

Junior Temperament and Character Inventory (JTCI)
The Junior Temperament and Character Inventory (JTCI) was developed to assess the temperament ('novelty seeking', 'harm avoidance', 'reward dependence', 'persistence') and character ('self-directedness', 'cooperativeness', 'self-transcendence') dimensions of Cloninger's bio-social model of personality in children and adolescents. Each of the 108 statements can be answered "True" or "False". The parent is to decide which choice best fits the child they are describing in this questionnaire.
