Original publication

Recorded summary

A cluster-randomised National Guard study followed 342 soldiers. HRV feedback did not reduce post-deployment PTSD symptoms across the whole sample. The age-related signal favoured older participants.

Recorded limitations

The on-site emWave games responded to HRV. The home prompt provided separate paced-breathing practice.

Evidence and provenance

Chapter Trust Factor uses a minimum of three distinct qualifying studies. Publication records retain their own evidence and assessment.
