Mindfulness in everyday life: between- and within-person relationships to motivational conflicts

Mindfulness mechanisms in everyday life: examining variance in acceptance, attention monitoring, decentering, self-compassion, and nonreactivity and their links to negative emotions among a workplace sample

Theoretical work proposes that acceptance, attention monitoring, decentering, self-compassion, and nonreactivity are mechanisms that explain beneficial effects of mindfulness training. Yet, whether these mechanisms represent independent constructs and whether they naturally vary within person is unclear. This study examined whether mindfulness mechanisms represent independent constructs that naturally fluctuate within a person over time, and whether these fluctuations differentially relate to negative emotions. A sample of university staff employees (n = 143; 74.8% female; M ± SDage = 38.2 ± 10.9; 53.8% White) reported on mindfulness mechanisms and negative emotions five times a day for four days for a total of 2,122 assessments. Four distinct mechanisms emerged - acceptance-attention, decentering, self-compassion, nonreactivity - that exhibit substantial moment-to-moment variation. Greater acceptance-attention, self-compassion, and nonreactivity were associated with lower negative emotions; greater decentering was associated with higher negative emotions when examined concurrently with the other mechanisms. The unique associations of all mindfulness mechanisms with negative emotions, combined with their high levels of variability from moment to moment, suggest their potential as targets for mindfulness interventions to improve emotional well-being.

Disentangling between- and within-person associations of psychological distress and mental well-being: An experience sampling study examining the dual continua model of mental health among university students

The dual continua model assumes that psychological distress and mental well-being are two related, yet distinct dimensions of mental health. Previous studies did convincingly show the distinctiveness of these two dimensions using mainly cross-sectional research. Despite the importance to distinguish between- and within-person associations in psychological theories, to date, no study specifically distinguished between- and within-person associations for the relationship between distress and well-being. Therefore, the objective of this study was to validate whether the dual continua model actually holds when examined within individuals. Intensive longitudinal data were collected through experience sampling. The sample included 25 university students (mean age = 23.50 years, 56% female), who completed a baseline questionnaire as well as momentary measures of psychological distress and mental well-being three times per day for two weeks. 1,014 timepoints were analyzed using multilevel models and person-mean centering was applied to distinguish between- and within person associations. A significant moderate negative between-person association was found for the relationship between psychological distress and mental well-being (β = -.363, marginal R 2 = 0.15, p < .001). The within-person association was also significant and similar in magnitude (β = -.432, marginal R 2 = 0.18, p < .001) at the group level. Individual within-person associations between distress and well-being varied substantially, but were negative for almost all participants. This study is an important step towards validating the applicability and universality of this widely used model. The current findings provide preliminary evidence that the dual continua model does not only hold between people, but also on the level it is actually used for, namely within individual people.
