Positive psychology (PP) is in its third wave, evolving towards an interdisciplinary study of wellbeing. This article proposes computational positive psychology (CPP) as an emerging interdisciplinary field that integrates PP with computational science and technology to advance the understanding of wellbeing and develop evidence-based strategies to promote sustainable flourishing. The key features of CPP include addressing novel research questions that have received limited investigation in the existing literature, collecting large-scale and multimodal data, constructing computational models, and utilizing the results to advance theories, research, and the practice of wellbeing. We review CPP research topics such as: (1) advancing theoretical wellbeing models, (2) efficiently measuring wellbeing and positive traits, (3) exploring interdependent dynamics between individual and systemic wellbeing, (4) enhancing positive psychology interventions, and (5) improving collective wellbeing. The transformative potential of CPP for understanding and promoting wellbeing in the digital era is highlighted, and future research directions are discussed. [ABSTRACT FROM AUTHOR]

Mindfulness can be viewed as an important dispositional characteristic that reflects the tendency to be mindful in daily life, which is beneficial for improving individuals’ both hedonic and eudaimonic well-being. However, no study to date has examined the brain regions involved in individual differences in dispositional mindfulness during the resting state and its relation with hedonic and eudaimonic well-being. To investigate this issue, the present study employed resting-state functional magnetic resonance imaging (rs-fMRI) to evaluate the regional homogeneity (ReHo) that measures the local synchronization of spontaneous brain activity in a large sample. We found that dispositional mindfulness was positively associated with the ReHo in the left orbitofrontal cortex (OFC), left parahippocampal gyrus (PHG), and right insula implicated in emotion processing, body awareness, and self-referential processing, and negatively associated with the ReHo in right inferior frontal gyrus (IFG) implicated in response inhibition and attentional control. Furthermore, we found different neural associations with hedonic (i.e., positive and negative affect) and eudaimonic well-being (i.e., the meaningful and purposeful life). Specifically, the ReHo in the IFG predicted eudaimonic well-being whereas the OFC predicted positive affect, both of which were mediated by dispositional mindfulness. Taken together, our study provides the first evidence for linking individual differences in dispositional mindfulness to spontaneous brain activity and demonstrates that dispositional mindfulness engages multiple brain mechanisms that differentially influence hedonic and eudaimonic well-being.

Although previous studies have established a link between daily gratitude and daily well-being, little is known about whether resilience and social support play the mediating role in the predictive effect of daily gratitude on daily well-being. To better understand how gratitude is linked to well-being, the present study adopted a daily diary method to explore the mediating roles. A sample of 153 undergraduates (Mage = 20.27 years, SDage = 1.83 years) completed the daily questionnaire once a day for 21 consecutive days. Multilevel within-subject mediation analyses indicated that daily resilience and daily social support mediated the relationship between daily gratitude and daily well-being. These findings are in line with the broaden-and-build theory, emphasizing the significant mediating roles of resilience and social support in the gratitude – well-being link at the within-person level.

Preceding research has demonstrated the positive relation between gratitude and well-being at the trait level, but less is known about the day-to-day association between them. This study investigated the within-person associations of gratitude with hedonic and eudaimonic well-being using a daily diary design. A sample of 363 young adults (M = 19.77, SD = 1.84) finished an online questionnaire once a day for 14 consecutive days. The results indicated that gratitude was positively related to hedonic and eudaimonic well-being on the same day, and gratitude positively predicted next-day hedonic and eudaimonic well-being, but not vice versa. We also found the reciprocal relation between the cognitive component of daily hedonic well-being (i.e., life satisfaction) and daily gratitude measured by the Gratitude Questionnaire. Moreover, these cross-lagged relations were not moderated by trait gratitude. These results provide supportive and convincing evidence for the positive effect of gratitude at the state level.

Hedonia and eudaimonia have been proposed as pathways to well-being. However, the direction of the causal relationship between them remains unclear. This study examined if happiness motivations may be resources leading to a happy life, or vice versa. Cross-lagged associations between happiness motivations (i.e. hedonic motivation and eudaimonic motivation) and subjective well-being (i.e. positive affect, negative affect, and life satisfaction) were tested. Four hundred and ninety-four Chinese adolescents (233 males; mean age 13.26 ± 0.70 years) participated in a two-wave paper and pencil study. The cross-lagged analysis showed that eudaimonic motivation was a significant predictor of positive affect and life satisfaction over time. No cross-lagged effects between eudaimonic motivation and negative affect, or between hedonic motivation and subjective well-being components were established. The results highlight the predictive power of eudaimonic motivation on adolescents' subjective well-being later on. [ABSTRACT FROM AUTHOR]

Previous studies have rarely explored the predictive causality relationship between trait gratitude and subjective well-being (SWB) that has been demonstrated to have a bi-factor structure (i.e., three specific factors and a general factor of SWB). A sample of 494 adolescents participated in a two-wave study including the measurements of trait gratitude and SWB. We employed structural equation modeling techniques to assess cross-lagged effects between trait gratitude and the bi-factor structure of SWB (i.e., life satisfaction, negative affect, positive affect and the general SWB factor) in four models. The results showed that trait gratitude could predict life satisfaction and positive affect, but could not predict negative affect and the general SWB factor over two months. Besides, there was no evidence for the reverse or reciprocal relationships between trait gratitude and the bi-factor structure of SWB. Implications and future directions of the findings were discussed. [ABSTRACT FROM AUTHOR]

Although the Wong and Law Emotional Intelligence Scale (WLEIS) has been validated in many studies, it has not been validated with bifactor model. Study 1 conducted a confirmatory factor analysis with a sample of 525 Chinese university students aged 18–30 years old, and found that the bifactor model with a general factor and four specific factors showed the best fit to the data. Study 2 cross-validated these findings in another 724 adult sample aged 17–56 years old, and the measurement invariance between students and employees was obtained. Besides, the results of Structural Equation Modeling demonstrated that the general factor could predict the three components of subjective well-being (i.e., life satisfaction, positive affect, and negative affect), but only the specific factor of Use of Emotion could predict positive affect. Moreover, there were no differences in these relations between students and employees. Implications and future directions of the findings were discussed. [ABSTRACT FROM AUTHOR]

Embryonic metanephros is the mammalian renal anlagen, which is considered as a potential source for the regeneration of functional whole kidneys. Some studies reported that metanephros implanted into unilateral nephrectomized animals can develop into kidney tissue. However, kidneys are nephrotoxic in renal failure patients, and whether metanephros can grow in nephrotoxic has not been reported. This study aims to investigate the growth of metanephros in acute nephrotoxic environment and analyze the therapeutic effect of metanephros microenvironment on acute kidney injury (AKI). AKI was induced in 200 g Wistar rats by giving intramuscular injections of 50% glycerol (10 mL/kg) in their hind limbs. 45 rats were divided randomly into three groups (control, glycerin, and metanephros). Metanephros group was transplanted two metanephroi (embryonic day 15) into the renal capsule of AKI rats. Glycerin group was AKI rats without transplantation. Control group was untreated. Mature glomeruli and tubules were detected in the grafts in metanephros group, which means that metanephroi can grow into tissues with mature kidney structure under acute nephrotoxic. Then, we assessed the renal function of host rats and found that there were fewer tubular necrosis in metanephros group than glycerin group, and the serum creatinine and urea nitrogen were significantly lower in metanephros group than glycerin group. These results suggested that embryonic metanephroi can grow into tissues with mature kidney structure under acute nephrotoxic, and the graft microenvironment was effective in inhibiting the progression of AKI, which provides a new approach for the treatment of acute renal injury.

Several psychological theories and models of wisdom have been developed. Despite converging trend from different theories and models in the understanding of wisdom, intervention plans or attempts to facilitate wisdom have been meager. In this study, different components of the MORE Life Experience Model of Wisdom were taken as intervention targets, and these components were targeted through mindfulness training, journal writing, narrative simulation, and case discussion on leadership virtues. The basic purpose was to seek the answer for the possibilityof development of wisdom in individuals by testing MORE modeland we plan to answer this by fulfilling two aims: first,to find empirical support for the MORE life experience model,we wanted to see whether MORE components predict participants’ self-rated wisdom scores; and second,to use this model as an intervention tool to foster wisdom.Intervention, lasted for 18 weeks, was done among 160 students (age range 19–22 years) enrolled for “leadership” course. Complete data were obtained from 108 participants. Result suggests Habitual Action (β = 0.24,p < 0.05), Personal Mastery (β = 0.24,p < 0.05), and Suppression (β = 0.20,p < 0.05) predicted Cognitive Wisdom; Personal Mastery (β = 0.34,p < 0.001;β = 0.43,p < 0.01) and Mindfulness (β = 0.23,p < 0.05;β = 0.26,p < 0.05) predicted Affective and Reflective Wisdom; and composite wisdom was predicted by Mindfulness (β = 0.33,p < 0.001) and Reappraisal (β = 0.24,p < 0.01). After intervention there were changes in Suppression (d = 0.34) and Habitual Action (d = 0.26). The study concluded with an affirmation to the conviction that wisdom may be amenable to the intervention. [ABSTRACT FROM AUTHOR]
