Character strength traits, states, and emotional well-being: A daily diary study

Abstract

Objective: Does whole trait theory work for character strengths? This study examines the daily within- and between-person variability of the manifestations of positively valued lower-order personality characteristics, namely character strengths, their convergence with trait character strengths, and their relationships to daily measures of affect. Background: Manifestations of personality traits vary both between- and within people. So far, research has focused on between-person differences in character strengths, while within-person differences have been neglected. Methods: German-speaking participants (N = 199, 84.3% women; mean age = 26.0 years) participated in a two-week daily diary study. They completed a baseline measure of character strength traits and daily measures of character strength states and positive and negative affect. Results: Results suggested that character strength traits converged well with aggregated states. Further, we observed high within-person variability in most character strengths. The trait-state convergence and the amount of within-person variability were predicted by whether the character strengths were rather phasic (i.e., more dependent on situational characteristics) or rather tonic (i.e., less dependent on situational characteristics). Higher within-person variability in character strengths was related to trait levels of perspective, honesty, social intelligence, and fairness. Regarding relationships between character strengths and affect, within-person associations were widely parallel to previously reported between-person associations and largely independent of trait levels of character strengths. Conclusion: These findings inform research on whole trait theory and character–strengths-based interventions.
