Study type
Description of intervention(s) / exposure
The intervention, the Pain Course, is an internet-delivered pain management program, which consists of:

(a) 5 online lessons provided over 8 weeks.
(b) A homework summary with assignments for each lesson
(c) Additional written resources that can be downloaded and which include information about other important skills, such as assertiveness and communication skills and techniques for managing sleep difficulties.
(d) Case Stories based on previous participants, which they can follow throughout the Course.
(e) Optional weekly contact with a Psychologist via secure email or telephone.

Participants will be encouraged to complete a lesson every 10 days and to read through a summary of the lesson and complete some basic homework in the following 10 days. Participants will have the option of contacting a Psychologist by phone or email each week for support with working through the course; each eCentreClinic Psychologist receives 1 hour or more of weekly supervision from another eCentreClinic Psychologist in which all of their participants are reviewed; as per best-practice guidelines and eCentreClinic Policy.

The Pain Course is based on cognitive behaviour therapy (CBT) principles and teaches evidence-based skills for managing pain, disability, anxiety and depression. Each lesson takes between 10 and 20 minutes to complete and it is suggested that participants read each lesson at least twice and spend approximately 3 hours, across the week, practicing the skills taught. Telephone calls will be limited to approximately 10 minutes per week; however, more time will be provided where clinically indicated. Adherence (e.g., logins, lesson completion, lesson views, time spent on course) will be monitored via the eCentreClinic software, which is used to provide the Pain Course.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants apply online via the clinic's website ( Successful applications are followed by a telephone interview to confirm suitability for the trial. Randomisation will occur prior to application and concealment occurs through the use of locked and concealed cells in a spreadsheet, which recruitment staff are required to open serially.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomized using a list generated prior to the study via a software program ( using permuted block randomisation.

Brief summary
The purpose of this proposed project is to replicate the efficacy of, and assess the cost-effectiveness, an established internet-delivered self-management program, the Pain Course, for chronic pain, when administered with optional clinician guidance versus a waitlist control. Participants in this research trial will be randomly allocated to receive the Course with optional telephone guidance from a clinician, or to a delayed-treatment control group.


1. The Pain Course will result in statistically and clinically significant improvements in symptoms of disability, anxiety and depression from pre-treatment to post-treatment compared to the treatment-as-usual Waitlist Control Group.

2. The Pain Course will be more cost-effective at common willingness-to-pay thresholds compared with treatment as usual.

3. Observed clinical improvements in symptoms of disability, anxiety and depression will be maintained at 3-month follow-up.
