Early indicators of vulnerability to depression: The role of rumination and heart rate variability.

J Affect Disord 2022 Jun 24. Epub 2022 Jun 24.

Department of General Psychology, University of Padua, Via Venezia 8, 35131 Padua, Italy; Padova Neuroscience Center (PNC), University of Padua, Via Orus 2/B, 35131 Padua, Italy.

Background: Despite the evidence of increased levels of rumination and reduced heart rate variability (HRV) in depression, whether these measures can be considered early indicators of vulnerability to depression has yet to be investigated. Therefore, the present study aimed to investigate both levels of rumination and resting HRV in individuals with familial risk for depression that is the most reliable risk factor for the disorder.

Methods: Rumination and vagally-mediated HRV were assessed using the Ruminative Response Scale and a smartphone-based photoelectric volumetric pulse wave assay, respectively, in 25 individuals who had family history of depression (but did not report current depressive symptoms), 15 individuals who reported depressive symptoms (but had no family history of depression), and 25 controls (without depressive symptoms and family history of depression).
