Description of intervention(s) / exposure
A simple randomised controlled trial (RCT) design will be used to evaluate the effectiveness of a online Cognitive Behavioural Therapy (CBT) program for decreasing the symptoms of panic and anxiety (called Panic eHealth).

Those that consent will be randomly allocated to one of 3 groups: 1) Panic eHealth program (with immediate access to all of the program modules) group, 2) Panic eHealth program (with weekly, sequential release of the program modules) group or to 3) a wait control group (delayed access to the Panic eHealth program with weekly, sequential release of modules).

Panic eHealth has six modules:

1. Psycho-education and self monitoring instruction of panic and anxiety
2. Physiological Control and Relaxation (e.g., controlled breathing to reduce symptoms)
3. Cognitive restructuring to reduce unhelpful thinking (catastrophising and probability over estimations) and cognitive flexibility strategies
4. Exposure and biofeedback – gradual exposure to panic symptoms and to feared/avoided places (situational)
5. Relapse prevention and increasing wellness


It should take approximately 20 minutes to complete each module, with the addition of 20-30 minutes to engage in recommended offline activities that serve to reinforce the information contained within each specific module.

Participants will also receive automated emails when they need to complete the questionnaires (and additional reminders when they fail to do so in a timely manner) as well as when they do not log on for a period of time, while they are undertaking the Panic eHealth program.

There will also be a booster session delivered two weeks following the post intervention assessment. This module will reinforce the key messages from the Panic eHealth modules and should take about 15 minutes to complete. An automated email will inform participants when the Booster module is available/released.

The two immediate access condition groups will continue to have access to the Panic eHealth program for the duration of the study (i.e., 19 weeks). Given the 10 week delay for the participants in the the wait list control, they will receive access to Panic eHealth for 9 weeks.

Eligibility
Key inclusion criteria
Participants must be 18 years or older, experience panic, have access to the internet, and be able to register online using an email address. Panic will be assessed via the Panic Disorder Severity Scale (PDSS) (1) as part of the baseline assessments. Those participants scoring below sub-clinical cut-offs for panic will be advised that this program would not have any benefit for them and they will be referred to MindHealthConnect (an online government funded e-mental health portal that provides information about various Australian mental health and wellbeing online services).
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Participants with no panic symptoms.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This is a fully automated online trial, as such the participant self registers online. If the screening criteria are met, the program software randomizes each participant to one of the three conditions and informs of this outcome.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The computer generated randomization procedure will employ a block design method.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?

Statistical methods / analysis
Repeated measures MANOVA and ANOVA.

Previous research has reported medium effects can be expected. Therefore, assuming a medium effect (i.e. GPower f(v) test = 0.40), significance set at 5% (p = .05), power at 80%, a sample of 40 will be required to demonstrate statistical significance. However allowing for a 50% attrition rate, we will be required to recruit 80 participants.

Reason for early stopping/withdrawal
Other reasons/comments
Other reasons
Given delays with getting the first digital platform ready to go 'live', a new program was written and uploaded during this 'delay wait time' and so this particular program was replaced with the more recent version. Therefore, there was no longer a need to run a trial on this 'older' version and so the study never commenced.
