About this study

Official title: A Randomised Controlled Trial Comparing Internet Based Cognitive Behavioural Therapy for Major Depressive Disorder Plus a Cognitive Bias Modification Intervention (OxIGen)on Symptoms of Depression and Negative Interpretation Bias.

A randomised controlled trial comparing Internet based cognitive behavioural therapy for major depressive disorder plus a cognitive bias modification intervention (OxIGen) version A vs. Internet based cognitive behavioural therapy for major depressive disorder plus a cognitive bias modification intervention (OxIGen) version B on symptoms of depression and negative interpretation bias.

Read the detailed description

Cognitive accounts of depression and anxiety emphasize the importance of cognitive biases in the maintenance of disorders. One specific bias is the interpretation of ambiguous information. A negative interpretation bias is defined as a systematic tendency to interpret potentially ambiguous information in a negative rather than benign way and this bias has been associated with symptoms of depression. Research has led to the recent development of computerized cognitive bias modification (CBM) techniques to augment such biases and it has been suggested that CBM techniques may be useful as an adjunct to current treatments to enhance maintenance of treatment gains and minimize relapse rates. The fact that CBM procedures lend themselves to being delivered remotely, are cost-effective, and can be self-paced in ways that suit the patient make them an ideal candidate for inclusion in the Internet-based cognitive behavioural therapy (iCBT) programs currently offered through St. Vincent's Hospital and the University of New South Wales. Therefore, the primary aim of the current trial is to evaluate the acceptability and effectiveness of adding CBM procedures to the existing iCBT modules offered through St. Vincent's Hospital and the University of New South Wales. It is expected that iCBT + CBM (active version) will result in superior treatment outcomes as indexed by a standardized clinical battery compared to iCBT + CBM (control version).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Patient Health Questionnaire-9 (PHQ-9)scores

    Measured: Administered at baseline (T1), post-CBM intervention (T2, 1 week after baseline), post iCBT intervention (8-10 weeks after baseline), and at 3 month follow-up (T4).

  2. Change in Beck Depression Inventory - second edition (BDI-II)scores

    Measured: Administered at baseline (T1), post-CBM intervention (T2, 1 week after baseline), post iCBT intervention (8-10 weeks after baseline), and at 3 month follow-up (T4).

  3. Change in Ambiguous Sentence Task (AST)scores

    Measured: Administered at baseline (T1), post-CBM intervention (T2, 1 week after baseline).

  4. Change in diagnostic status (MINI5 depression module)

    Measured: Administered at baseline (T1), post iCBT intervention (8-10 weeks after baseline), and at 3 month follow-up (T4).

Secondary outcomes (5)
  1. Change in Kessler-10 (K10)scores

    Measured: Administered at baseline (T1), post-CBM intervention (T2, 1 week after baseline), post iCBT intervention (8-10 weeks after baseline), and at 3 month follow-up (T4).

  2. Change in WHO Disability Assessment Scale (WHO-DAS)scores

    Measured: Administered at baseline (T1, post iCBT intervention (8-10 weeks after baseline), and at 3 month follow-up (T4).

  3. Change in State Trait Anxiety Inventory (STAI)scores

    Measured: Administered at baseline (T1), post iCBT intervention (8-10 weeks after baseline), and at 3 month follow-up (T4).

  4. Change in Repetitive Thinking Questionnaire (RTQ)scores

    Measured: Administered at baseline (T1), post-CBM intervention (T2, 1 week after baseline), post iCBT intervention (8-10 weeks after baseline), and at 3 month follow-up (T4).

  5. Change in Clinical Perfectionism Scale (PCS)scores

    Measured: Administered at baseline (T1), post iCBT intervention (8-10 weeks after baseline), and at 3 month follow-up (T4).

Questions about this trial

What is this clinical trial studying?

A study testing CBM and iCBT in people with Depression, run by St Vincent's Hospital, Sydney at 1 site in Australia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Aug 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Patient Health Questionnaire-9 (PHQ-9)scores (time frame: Administered at baseline (T1), post-CBM intervention (T2, 1 week after baseline), post iCBT intervention (8-10 weeks after baseline), and at 3 month follow-up (T4).). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01787513, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
