Key result
The Adult Attachment Interview significantly increased the low frequency/high frequency heart rate variability ratio in patients with dissociative disorders (pre-AAI 1.91 vs post-AAI 4.03; p=0.005).

Does the Adult Attachment Interview alter heart rate variability in individuals with dissociative disorders compared to healthy controls?
The Adult Attachment Interview induces significant changes in heart rate variability among patients with dissociative disorders, suggesting physiological correlates of emotion dysregulation.
AAI was associated with increased LF/HF ratio in dissociative disorders; leaves open specificity versus controls and clinical relevance.
The aim of this study was to assess heart rate variability (HRV) in individuals with dissociative disorders (DD) before and after the Adult Attachment Interview (AAI). Electrocardiograms were recorded before, during, and after the AAI in 13 individuals with DD and 13 healthy participants matched for age and gender. Significant change in HRV was observed only in the DD group. After the AAI, those with DD showed significant increases in the low frequency/high frequency ratio (pre-AAI = 1.91 ± 1.19; post-AAI = 4.03 ± 2.40; Wilcoxon test = -2.76, p = .005). Our results suggest that the retrieval of childhood attachment experiences in individuals with DD is associated with a change in HRV patterns that could reflect the emotion dysregulation of dissociative psychopathological processes.

Farina et al. (2014) conducted a case-control in Dissociative disorders (n=26). Adult Attachment Interview (AAI) vs. Healthy participants and pre-AAI baseline was evaluated on Change in heart rate variability (low frequency/high frequency ratio) (p=0.005). The Adult Attachment Interview significantly increased the low frequency/high frequency heart rate variability ratio in patients with dissociative disorders (pre-AAI 1.91 vs post-AAI 4.03; p=0.005).
