About this study

The study is designed to evaluate the effect of a novel computer training program on PTSD.

Read the detailed description

Post-traumatic stress Disorder (PTSD) is a chronic and debilitating disorder that affects millions of people each year (Kessler et al., 2005). Although effective psychosocial and pharmacological treatments exist for this disorder, as many as 50 percent of individuals still experience symptoms after treatment (Schottenbaeur et al., 2008). Empirical literature suggests that cognitive deficits may play a role in maintaining symptoms in individuals with PTSD through a variety of mechanisms, including decreased cognitive control over intrusive thoughts (Verwoerd et al., in press) and dysregulation in neural circuitry linking prefrontal cognitive control functions and amygdala activity (McNally, 2007). The goals of the proposed research are to improve the candidate's understanding of cognitive mechanisms of PTSD symptoms while building skills in conducting treatment research. The application aims to test a novel methodology for approaching PTSD treatment based on modification of underlying cognitive mechanisms of the disorder. To this end, 50 participants with PTSD will be randomly assigned to an 8-session executive control training condition designed to improve working memory functioning or a control condition. The aims of this study are 1) To test the effect of a working memory training program on working memory performance and 2) To examine the effects of this program on PTSD symptoms. The research plan is complemented by a set of training goals for the candidate to achieve over the proposed award period. These include 1) training in the use of fMRI and neuropsychological assessment 2) additional coursework and seminars in cognitive science and biostatistics for use in future work, 3) experience with teaching in the undergraduate and graduate setting and presenting original work for publication in preparation for a career in academic research. Taken together, the research and training components of this grant application will facilitate the candidate's long-term goal of conducting treatment outcome and basic mechanism research in PTSD. Moreover, as per the strategic plan outlined by NIMH, this application is designed develop an innovative intervention based on prior clinical research and knowledge of cognitive and neurobiological features of the disorder, and will advance knowledge of mechanisms of fear learning. It is designed to target core cognitive features of the disorder in an effort to reduce symptoms. PUBLIC HEALTH RELEVANCE: Post-traumatic stress disorder impacts millions of Americans, and is associated with significant personal distress as well as societal cost. The current application is designed to examine the effect of a novel working memory training program on PTSD symptoms. This approach is promising in that it may be a cost- effective and accessible method for decreasing symptoms associate with this disorder.

What is being measured

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

  1. Change in Clinician Administered PTSD Scale; Re-experiencing

    Model estimations of the means and standard deviation of posttreatment score at the mean level of baseline severity reported below.

    Scale range: 0-40, higher values indicate greater symptom severity

    Measured: Baseline, Week 4

Secondary outcomes (4)
  1. Clinician Administered PTSD Scale Total Score - Responder Status

    Number of Participants Who Responded According to Clinician Administered PTSD Scale Total Score

    Measured: Week 4

  2. Change in Depression: Beck Depression Inventory

    Scale Range: 0-63; higher scores indicate greater symptom severity

    Measured: Baseline, Week 4

  3. Change in General Anxiety: Spielberger State-Trait Anxiety Inventory

    Range: 20-80; higher scores indicate greater symptom severity

    Measured: Baseline, Week 4

  4. Change in Functional Impairment; Sheehan Disability Scale

    Range: 0-30; greater values indicate greater disability severity ratings

    Measured: Baseline, Week 4

Questions about this trial

What is this clinical trial studying?

A study testing Computerized Cognitive Training - active in people with Posttraumatic Stress Disorder, run by Rick Gulizia.

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 3 inclusion and 5 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 6 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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?

Yes. Results are posted in the registry (first posted 7 Mar 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 Clinician Administered PTSD Scale; Re-experiencing (time frame: Baseline, Week 4). 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 NCT02139137, 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2017.
