In this study, we examine whether two positive psychological indicators, Flow Frequency, Coping, and one negative psychological indicator, Trait-Anxiety can be determined based on heart rate parameters. The experiment is conducted on 16 healthy subjects, and their heart rate is recorded using a Fitbit Charge 2 device. To acquire heart rate parameters, four cosinor-based variables such as cosinor 24-Hour periodic component, cosinor 12-Hour periodic component, cosinor periodic component amplitude, and cosinor autonomic switching rate are extracted from the original heart rate sequence during 24 hours by using the double cosinor method. We measure psychological indicators by employing dispositional questionnaires. The PCA results show a substantial correlation in Flow Frequency and Coping (R2>0.3, p<0.05 with a single principal component and R2>0.4, p<0.05 with multiple principal components). Trait-Anxiety demonstrates a negative correlation with physiological parameters. According to this finding, there is a positive correlation between positive psychological indicators and heart rate parameters.
