Abstract:Aim: This study explored whether the digital biomarkers EDA and PRV had between- and within-person associations with positive and negative emotions in young adults, in a real-time longitudinal framework. Methods: The study used the experience sampling method (ESM). Thirty-four young adults completed a daily questionnaire in m-Path to self-report positive and negative emotions and wore an EmbracePlus smartwatch measuring EDA and PRV over 8 measurement days. Person-centred mean analysis combined with multilevel models was used. Results: Significant negative between-person associations were found between EDA (p < .001) and PRV (p = .002) with positive emotions, while significant (p < .001) positive between-person associations of EDA with negative emotions were found. Conversely, PRV had no significant positive between-person associations with negative emotions. No significant within-subject associations between EDA and PRV with positive and negative emotions were found. Conclusion: Neither EDA nor PRV significantly affect within-person levels of positive and negative emotions. Significant between-person associations of EDA and PRV suggest that overall averages, rather than daily fluctuations, may be more relevant for assessing emotion valence.
