Results Overview

The Panic Disorder Severity Scale (PDSS) is a clinician-administered questionnaire used to assess the severity of panic attacks. The PDSS consists of seven items with each ranging in severity from 0 (none) - 4 (extreme); so total score ranges from 0 to 28.

PRIMARY outcome

Timeframe: Baseline, Post-Treatment (end of week 8)

Population: While 27 participants were allocated to the CBPT intervention, 3 dropped out before the baseline session. Similarly, 26 participants were allocated to the MRT intervention but 2 dropped out before the baseline session. Accordingly, outcome measures were analyzed for the 48 participants (24 in each arm) that completed their baseline sessions.

Similarly, 26 participants were allocated to the MRT intervention but 2 dropped out before the baseline session. Accordingly, outcome measures were analyzed for the 48 participants (24 in each arm) that completed their baseline sessions.

Dosers (electronic devices used to monitor the usage of metered-dose inhalers) were attached to participants' asthma rescue inhalers to count the number of puffs of medication used during the treatment period. Use of rescue medication was then coded as good asthma control (less than or equal to rescue medication use twice a week) or poor control (rescue medication use greater than two days a week) in accordance with national guidelines (NHLBI, 2007).

The CGI is a 2-item scale rated by clinicians to assesses for a patient's functioning prior and subsequent to the implementation of an intervention. In the current study, the CGI was used to assess panic disorder illness severity in patients as well as identify whether subjects responded to the study intervention. The CGI scale includes a question on level of improvement subsequent to intervention ranging from 1 (very much improved) to 7 (very much worse), and a question on severity of illness ranging from 1 (normal) to 6 (among the most extremely ill of patients). To be a treatment responder, a participant had to have a score of 2 (much improved) or better and be rated as a 3 (mild) or less on their illness severity.

The ACQ is a self-report questionnaire to assess asthma control based on asthma symptoms, nighttime awakenings, and use of rescue medication for asthma. Each item is given a score from 0 to 6 with lower scores indicating better asthma control. The ACQ total scale score is an average of the item questions, with scores ranging between 0 (well controlled) and 6 (extremely poorly controlled).

Self-report measure of adherence to controller medications with 10 items ranging from 1 (always) to 5 (never). Higher mean scores indicate greater adherence and a score \> 4.5 is considered good adherence.
