  • Mindfulness based flourishing program: A cross-cultural study of Hong Kong Chinese and British participants
  • 2018

    • The Mindfulness Based Flourishing Program (MBFP) is an online 8-week intervention developed for enhancing wellbeing with the use of mindfulness practices, through targeting a range of positive variables. The efficacy of the MBFP has been demonstrated in a randomized controlled trial, and in order to further establish it as an intervention with widespread application, cross-cultural validation is warranted. The current study was conducted with the primary aim of testing the validity of the MBFP with a Hong Kong Chinese population, as well as verifying its positive effects. A randomized wait-list controlled design was adopted with 115 participants (92 females, mean age = 31.50). Intervention outcomes were compared between Hong Kong Chinese and British participants. Five positive variables were examined (self-compassion, meaning in life, positive and negative emotions, gratitude, and mindfulness), and measures were taken pre- and post-intervention. Significant gains in wellbeing measures were observed in both the Hong Kong Chinese and the British experimental groups. Levels of wellbeing post-intervention were also higher for the two experimental groups as compared to their control counterparts. The current study provides preliminary evidence for the MBFP’s cross-cultural validity, and strengthens previous claims for its efficacy as a new, accessible alternative for enhancing wellbeing.

  • The Cantril Ladder elicits thoughts about power and wealth
  • 2024
  • Ingår i: Scientific Reports. - 2045-2322. ; 14:1
  • Tidskriftsartikel (refereegranskat)abstract
    • The Cantril Ladder is among the most widely administered subjective well-being measures; every year, it is collected in 140+ countries in the Gallup World Poll and reported in the World Happiness Report. The measure asks respondents to evaluate their lives on a ladder from worst (bottom) to best (top). Prior work found Cantril Ladder scores sensitive to social comparison and to reflect one’s relative position in the income distribution. To understand this, we explored how respondents interpret the Cantril Ladder. We analyzed word responses from 1581 UK adults and tested the impact of the (a) ladder imagery, (b) scale anchors of worst to best possible life, and c) bottom to top. Using three language analysis techniques (dictionary, topic, and word embeddings), we found that the Cantril Ladder framing emphasizes power and wealth over broader well-being and relationship concepts in comparison to the other study conditions. Further, altering the framings increased preferred scale levels from 8.4 to 8.9 (Cohen’s d = 0.36). Introducing harmony as an anchor yielded the strongest divergence from the Cantril Ladder, reducing mentions of power and wealth topics the most (Cohen’s d = −0.76). Our findings refine the understanding of historical Cantril Ladder data and may help guide the future evolution of well-being metrics and guidelines.

  • Evaluation of climate-related carbon turnover processes in global vegetation models for boreal and temperate forests
  • 2017
  • Ingår i: Global Change Biology. - : Wiley. - 1354-1013 .- 1365-2486. ; 23:8, s. 3076-3091
  • Tidskriftsartikel (refereegranskat)abstract
    • Turnover concepts in state-of-the-art global vegetation models (GVMs) account for various processes, but are often highly simplified and may not include an adequate representation of the dominant processes that shape vegetation carbon turnover rates in real forest ecosystems at a large spatial scale. Here, we evaluate vegetation carbon turnover processes in GVMs participating in the Inter-Sectoral Impact Model Intercomparison Project (ISI-MIP, including HYBRID4, JeDi, JULES, LPJml, ORCHIDEE, SDGVM, and VISIT) using estimates of vegetation carbon turnover rate (k) derived from a combination of remote sensing based products of biomass and net primary production (NPP). We find that current model limitations lead to considerable biases in the simulated biomass and in k (severe underestimations by all models except JeDi and VISIT compared to observation-based average k), likely contributing to underestimation of positive feedbacks of the northern forest carbon balance to climate change caused by changes in forest mortality. A need for improved turnover concepts related to frost damage, drought, and insect outbreaks to better reproduce observation-based spatial patterns in k is identified. As direct frost damage effects on mortality are usually not accounted for in these GVMs, simulated relationships between k and winter length in boreal forests are not consistent between different regions and strongly biased compared to the observation-based relationships. Some models show a response of k to drought in temperate forests as a result of impacts of water availability on NPP, growth efficiency or carbon balance dependent mortality as well as soil or litter moisture effects on leaf turnover or fire. However, further direct drought effects such as carbon starvation (only in HYBRID4) or hydraulic failure are usually not taken into account by the investigated GVMs. While they are considered dominant large-scale mortality agents, mortality mechanisms related to insects and pathogens are not explicitly treated in these models.

  • Self-Transcendence as a Buffer Against COVID-19 Suffering : The Development and Validation of the Self-Transcendence Measure-B
  • 2021
  • Ingår i: Frontiers in Psychology. - : Frontiers Media SA. - 1664-1078. ; 12
  • Tidskriftsartikel (refereegranskat)abstract
    • The age of COVID-19 calls for a different approach toward global well-being and flourishing through the transcendence suffering as advocated by existential positive psychology. In the present study, we primarily explained what self-transcendence is and why it represents the most promising path for human beings to flourish through the transformation of suffering in a difficult and uncertain world. After reviewing the literature on self-transcendence experiences, we concluded that the model of self-transcendence presented by Frankl is able to integrate both of the characteristics associated with self-transcendence. Afterward, we discussed how the self-transcendence paradigm proposed by Wong, an extension of the model by Frankl, may help awaken our innate capacity for connections with the true self, with others, and with God or something larger than oneself. We presented self-transcendence as a less-traveled but more promising route to achieve personal growth and mental health in troubled times. Finally, we presented the history of the development and psychometrics of the Self-Transcendence Measure-Brief (STM-B) and reported the empirical evidence that self-transcendence served as a buffer against COVID-19 suffering. The presented data in the current study suggested that the best way to overcome pandemic suffering and mental health crises is to cultivate self-transcendence.
