Outcome measures
Primary outcome
Our main outcome is appraisal style, as expressed by the *Appraisal Score*.
Furthermore, we want to investigate if CBM-app training influences negative
cognitions post training, as measured by the Post Traumatic Cognition Inventory
(PTCI).
Secondary outcome
- Interpretation bias will be measured with the Word Sentence Association
Paradigm (WSAP).
- Further, participants provide information on PTSD symptoms (Posttraumatic
Scale Self-Report, PSS-SR) via self-report.
- Finally, we will investigate if CBM-app training influences negative
cognitions post training, as measured by the frequency and credibility of their
most important, trauma-related cognition and by the frequency and amount of
distress provoked by their most important, trauma-related re-experience in the
preceding week (Hagenaars, et al., 2010).
Background summary
Posttraumatic stress disorder (PTSD) is characterized by dysfunctional
cognitions, such as negative appraisal of the trauma and its consequences.
Cognitive behavioral therapy (CBT) is a proven effective treatment for PTSD and
has been shown to reduce dysfunctional cognitions. Notwithstanding the efficacy
of CBT, there is room for improvement since remission rates tend to be low.
Cognitive Bias Modification (CBM) is a computerized training technique that
directly and systematically targets dysfunctional cognitive biases. CBM proved
efficacious in reducing dysfunctional cognitive biases and anxiety symptoms in
diverse populations, as well as in analogue trauma. However, only few studies
have examined CBM specifically in PTSD patients.
Study objective
First, we want to examine whether a CBM training aimed at inducing positive
appraisal style (positive CBM-app) can alter dysfunctional appraisal styles in
PTSD patients. Second, we want to examine whether this CBM-app training has an
effect on PTSD related dysfunctional cognitions and PTSD symptoms.
Study design
The planned study is a randomized clinical trial.
Intervention
Participants will be randomly allocated to receive either positive CBM-app or
neutral CBM-app training. Training will consist of four 20-30 minutes training
sessions that will have to be completed during one week. Training sessions can
be completed online, at a location of participants* choice (e.g., at home, at
treatment facility).
Study burden and risks
We believe the burden and risk to be minimal. Participants will have to invest
time for trainings and assessments. The training is timed during the waiting
list period before regular treatment implying that it does not interfere with
care as usual. No restrictions are imposed on psychological/medical treatment
for study purposes. Hypothetically, we expect those who receive positive
CBM-app to benefit from such training, however this has yet to be determined.
