Note: MASQ-S = Mood and Anxiety Symptom Questionnaire – Short Form; RSQ-RSS = Response Styles Questionnaire – Ruminative Response Scale; IA = Interoceptive Awareness (indexed by heartbeat counting accuracy); bpm = beats per minute; HR = heart rate; SDNN = Standard deviation of normal-to-normal R-R intervals.
a
Correlation is significant at the 0.05 level (2-tailed).
b
Correlation is significant at the 0.01 level (2-tailed).
