Evaluating web-based cognitive-affective remediation in recent trauma survivors: study rationale and protocol

Area of Science:

• Neuroscience
• Psychology
• Digital Health

Background:

• Traumatic events create a period of heightened neural plasticity, influencing PTSD development.
• Impaired emotional reactivity, regulation, and executive functions are key contributors to PTSD.
• Adult neural mechanisms remain plastic, suggesting targeted retraining can prevent PTSD.

Purpose of the Study:

• To evaluate the direct effects of cognitive remediation training on neurocognitive mechanisms implicated in PTSD.
• To assess the indirect impact of this intervention on the emergence of PTSD symptoms.
• To present a study design for early, web-based interventions targeting PTSD's causative mechanisms.

Main Methods:

• Described study rationale, design, and methodological choices for participant enrollment.
• Detailed implementation of a daily, self-administered, web-based cognitive remediation intervention.
• Outlined procedures for screening, assessment, control conditions, outcome measures, and interviewer management.

Main Results:

• The study evaluated direct effects on neurocognitive mechanisms and indirect effects on PTSD symptoms.
• Methodological choices regarding sample, timing, measurements, and adherence were outlined.
• Strategies for harmonizing interviewer fidelity and mitigating burnout were detailed.

Conclusions:

• Early, web-based interventions targeting PTSD's causative neurocognitive mechanisms are feasible.
• The presented model informs the development of timely, accessible PTSD prevention strategies.
• This approach leverages neural plasticity in the aftermath of trauma for intervention.
