Outcome Measures
Primary Outcomes (4)
Screening and Consent Rates
The number of patients with CNCP and suspected major depression who are referred for screening will be recorded. Eligibility rate will be calculated as the number of patients who meet full inclusion criteria divided by the number of patients referred for screening. Number of patients declining referral for screening and reasons for exclusion will be documented. Consent rate will be calculated by dividing the number of patients who consent to undergoing randomization by the number who met full inclusion criteria.
Through study completion, up to 2-years
Change in symptoms of depression measured using the Patient Health Questionnaire - 9 (PHQ-9)
Change in symptoms of depression as measured using the PHQ-9 from baseline to post-intervention. Scores range from 0-27 with higher scores reflecting greater symptoms of depressed mood.
Change from baseline to end of treatment (i.e., week 8).
Adherence to intervention measured as frequency of visits to online modules.
Intervention adherence will be measured using data recorded by Therapist Assisted Online (TAO) program and include: 1) frequency of visits to TAO modules throughout weeks 1 to 8.
End of treatment (i.e., week 8)
Perceived acceptability of treatment measured using qualitative interviews
Acceptability data will be collected using semi-structured interviews with patients. Open ended questions will be asked to ascertain the following: 1) acceptability of the delivered intervention; 2) perceived value, benefits, harms and unintended consequences of the delivered intervention; 3) perceived need for refinement of the delivered intervention.
Completion of the intervention (i.e., week 8)
Secondary Outcomes (6)
Change in physical function measured using the pain interference subscale of the Brief Pain Inventory - Short Form (BPI-SF)
Baseline, 4-weeks, and post-intervention (i.e., week 8)
Change in emotion function measured using the Depression, Anxiety Stress Scale - 21 (DASS-21).
Baseline and through study completion, an average of 8-weeks.
Change in pain severity will be measured using the pain severity composite scale of the Brief Pain Inventory - Short Form (BPI-SF)
Baseline and through study completion, an average of 8-weeks.
Change in psychological flexibility measured using the Multidimensional Psychological Flexibility Inventory (MPFI).
Baseline and through study completion, an average of 8-weeks.
Mediators of change for cognitive behavioural therapy measured using change in the cognitive behavioural therapy skills questionnaire.
Baseline and through study completion, an average of 8-weeks.

- Masking Details
- A research assistant not affiliated with the study will use Research Randomizer (http://www.randomizer.org/) to generate lists of randomly sequenced numbers to allocate patients to trial arm. To reduce biases and expectation effects, the research assistant will not be aware of what condition the patients are allocated when conducting baseline assessments and a research assistant not affiliated with the research will complete outcome assessments without being aware of allocation. Interventionists will be aware of which group patients are allocated to, as will patients.
