Abstract

Identifying momentary influences on ambulatory blood pressure (ABP) will help explain ABP variability; however, most research only examines aggregate ABP at the between-person level. This study used within-person methods to examine whether affective dimensions—valence and arousal—differentially predicted momentary ABP levels. A community sample (n = 39) wore an ABP cuff that took BP measurements every 20 min for 24 h. At each measurement, participants reported levels of valence and arousal on electronic diaries. Multilevel modeling was used to examine the effects of momentary and person-averaged levels of valence and arousal on ABP. Greater momentary negative valence and arousal predicted higher systolic BP compared to more positive or lower arousal assessments; higher averaged levels of arousal predicted higher DBP. The results suggest the independence of the effects of valence and arousal on BP. These findings have important implications for designing interventions to lower ABP.
