Claim — HRV Biofeedback Reduces CU Traits

2026 formulation

Fanti's EFCAP and EAPL keynote abstracts state that HRV biofeedback is associated with decreases/reductions in callous-unemotional traits.

Evidence mapped

The results-bearing Petridou dissertation uses CU traits primarily as a differentiation/moderation variable and reports physiological stress-response changes after HRV biofeedback.

Missing evidentiary link

No public result located in the dissertation audit demonstrates a pre/post reduction in CU trait scores attributable to the intervention.

A Petridou–Fanti manuscript on externalizing and internalizing problems is currently listed as under review, but no public results-bearing version was located.

Status

Unresolved keynote claim. Do not encode as demonstrated treatment effect.
