Description of intervention(s) / exposure
There will be an information sheet provided at ED and a client consent form with information about the trial and that all participation is voluntary. The patients will also be provided information about the treatment and that they have a right to withdraw at any point in time. The intervention will consist of Cognitive Behaviour Therapy which will target non cardiac chest pain as a symptoms
it will be delivered by a fully registered psychologist
it will be delivered as a face to face intervention for 6 sessions over 6 to 8 weeks
the duration of any single session will generally be 1 hour per week
the intervention will be delivered from the Townsville Hospital
assessing the adherence to intervention will be a part of the psychotherapy

Key inclusion criteria
All patients aged 18 to 65yrs who present to THHS ED with a discharge diagnosis of non-cardiac chest pain (NCCP) during the study period,.
Minimum age
18 Years
Maximum age
65 Years
Both males and females
Can healthy volunteers participate?
Key exclusion criteria
Since therapy involves providing standard psychotherapy which involves a fair degree of proficiency with English language, it is proposed that the following are excluded from this RCT in the interest of controlling for relevant variables:
• Individuals with limited proficiency in English language or with sensory or other impairment which impacts on expression and comprehension of English language
• Individuals from indigenous or culturally and linguistically diverse backgrounds
In addition it is suggested that individuals with the following conditions be excluded from this study
i. Those who have an underlying cardiac pathology – for the purpose of the study this is defined as individuals who have a diagnosed coronary artery disease This is because this represents a high-risk group who might need to re-present to the ED and therefore any gains made due to psychotherapy might not be best reflected through ED representations as the primary measure of the intervention's success.
ii. Individuals who have a co-morbid neurological condition: This includes a group of individuals who have had stroke or a space occupying lesion or those with a history of seizure disorder. Once again this represents a high-risk group who might need to re-present to the ED and therefore any gains made due to psychotherapy might not be best reflected through ED representations as the primary measure of the intervention's success
iii. Individuals who have a co-morbid psychiatric condition for which they are on psychotropic medication:

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will not be concealed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Individuals will be randomized to either the treatment or non-treatment conditions. Block randomization will be used to ensure there are approximately equal numbers of participants allocated to intervention and control groups (ratio of 1:1). For the purpose of randomization, we will use a computer-generated code, using the site www.randomization.com .
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

The people assessing the outcomes
Intervention assignment
Other design features
individuals will be randomly allocated as described above. The study will be single blinded. The assessors responsible for collecting the information at baseline, and the 8, 16 and 24 week follow up periods will be blind to the group (i.e. treatment or control) to which patients have been randomized. The participants however will not be able to be blinded. Those who are allocated to the treatment condition will be informed that as a part of the study they will be required to attend up to six sessions with a psychologist
Not Applicable
Type of endpoint(s)
Statistical methods / analysis
For continuous variables, independent samples t-tests will be used to determine whether there are differences between groups at baseline. Chi-squared tests will be used for categorical variables. At each follow-up point, difference scores will be calculated to represent the difference between baseline score and follow-up score at that time point. Between group analyses will then be conducted to assess differences on the various outcome measures, adjusting for relevant confounding variables. In addition, event rates will be calculated for each outcome measure, and relative risks calculated (event rate in intervention group divided by event rate in control group). This relative risk will then be used to calculate a range of relevant relative and absolute measures (Relative Risk Reduction, Absolute Risk Reduction, Number Needed to Treat).

Brief summary
The primary aim of the study is to reduce the number of ED re-presentations in the target population. Specifically, the aim of this study is to determine whether there are differences in outcomes for individuals who present to ED with non-cardiac chest pain and receive psychological intervention vs those who receive usual care, in relation to ED re-presentations over a 6-month period.
The secondary aim is to study if the intervention will result in an improvement in other patient outcomes, such as symptomatology, the quality of life and reduction in psychological distress and whether or not this intervention is cost effective
This is a Single-blind randomised controlled trial in which the assessor is blind to treatment vs standard care condition.
All individuals who meet the selection criteria will be invited to participate in the research. Consenting participants who meet the selection criteria, will be randomly allocated to either -:
A) Psychological treatment group consisting of 6 sessions of psychotherapy over 6-8 weeks, which will be conducted by a fully qualified Psychologist (Director of Psychology, THHS)
B) Usual care/ Wait list controls (Wait list controls have been included to ensure that all patients in the trial have access to treatment eventually should they so desire, since this treatment is evidence based)

Outcomes will be assessed for both groups at baseline, 8 weeks; 16 weeks and 24 weeks.
