The notion of spirituality is increasingly prominent in academic and cultural discourse alike. However, it remains a nebulous concept, capable of diverse interpretations, particularly cross-culturally. In the interest of exploring this diversity, yet also with the aim of identifying common themes, an enquiry was conducted into conceptualizations of spirituality across cultures. Specifically, the enquiry focused on so-called untranslatable words, i.e., which lack an exact equivalent in another language (in this case, English). Through a quasi-systematic search, together with conceptual snowballing, over 200 relevant terms were located. A grounded theory analysis identified three key dimensions: the sacred, contemplative practice, and self-transcendence. Based on these, a conceptualization of spirituality was formulated that may be valid cross-culturally, namely: engagement with the sacred, usually through contemplative practice, with the ultimate aim of self-transcendence.
Efforts to improve the well-being of healthcare professionals include mindfulness-based interventions (MBIs). To understand the value of such initiatives, we conducted a systematic review and meta-analysis of empirical studies pertaining to the use of MBIs with healthcare professionals. Databases were reviewed from the start of records to January 2016 (PROSPERO registration number: CRD42016032899). Eligibility criteria included empirical analyses of well-being outcomes acquired in relation to MBIs. Forty-one papers met the eligibility criteria, consisting of a total of 2101 participants. Studies were examined for two broad classes of well-being outcomes: (a) “negative” mental health measures such as anxiety, depression, and stress; (b) “positive” indices of well-being, such as life satisfaction, together with outcomes associated with well-being, such as emotional intelligence. MBIs were generally associated with positive outcomes in relation to most measures (albeit with moderate effect sizes), and mindfulness does appear to improve the well-being of healthcare professionals. However, the quality of the studies was inconsistent, so further research is needed, particularly high-quality randomised control trials.
Objective: Among efforts to improve the well-being of healthcare professionals are initiatives based around mindfulness meditation. To understand the value of such initiatives, we conducted a systematic review of empirical studies pertaining to mindfulness in healthcare professionals. Method: Databases were reviewed from the start of records to January 2016. Eligibility criteria included empirical analyses of mindfulness and well-being outcomes acquired in relation to practice. 81 papers met the eligibility criteria, comprising a total of 3,805 participants. Studies were principally examined for outcomes such as burnout, distress, anxiety, depression, and stress. Results: Mindfulness was generally associated with positive outcomes in relation to most measures (although results were more equivocal with respect to some outcomes, most notably burnout). Conclusion: Overall, mindfulness does appear to improve the well-being of healthcare professionals. However, the quality of the studies was inconsistent, so further research is needed, particularly high-quality randomized controlled trials.

Although wellbeing tends to be associated with positive affect, the phenomenological terrain in this regard is often poorly differentiated. In the interest of bringing further granularity to this area, an enquiry was conducted into relevant concepts found across the world’s cultures, focusing specifically on so-called untranslatable words. Through a quasi-systematic search of academic and grey literature, together with conceptual snowballing, 134 relevant terms have been located so far (with the process of enquiry ongoing). Through a process of grounded theory analysis, seven main themes were identified: peace/calm; contentment/satisfaction; cosiness/homeliness; savouring/appreciation; revelry/fun; joy/euphoria; and bliss nirvāṇa. The analysis highlights the need for a more expansive and granular conceptualisation of positive affect, one that recognises the depth and breadth of the subjective terrain that it covers.

Abstract: Since its emergence in 1998, positive psychology has flourished. Among its successes is the burgeoning field of applied positive psychology (APP), involving interventions to promote wellbeing. However, the remit of APP is currently unclear. As such, we offer a conceptual map delineating the terrain that APP might conceivably cover, namely, the LIFE (Layered Integrated Framework Example) model. The model is based on Wilber’s (1997) Integral Framework, which features the four main ontological ‘dimensions’ of the person. We then stratify these dimensions to produce a comprehensive conceptual map of the person, and of the potential areas of application for APP. For example, we deconstruct the collective dimensions of Wilber’s framework using the levels of Bronfenbrenner’s (1977) experimental ecology. The result is a detailed multidimensional framework which facilitates a comprehensive approach to promoting wellbeing, and which charts a way forward for APP.
Abstract: Positive psychology has tended to be defined in terms of a concern with ‘positive’ psychological qualities and states. However, critics of the field have highlighted various problems inherent in classifying phenomena as either ‘positive’ or ‘negative.’ For instance, ostensibly positive qualities (e.g., optimism) can sometimes be detrimental to wellbeing, whereas apparently negative processes (like anxiety) may at times be conducive to it. As such, over recent years, a more nuanced ‘second wave’ of positive psychology has been germinating, which explores the philosophical and conceptual complexities of the very idea of the ‘positive.’ The current paper introduces this emergent second wave by examining the ways in which the field is developing a more subtle understanding of the ‘dialectical’ nature of flourishing (i.e., involving a complex and dynamic interplay of positive and negative experiences). The paper does so by problematizing the notions of positive and negative through seven case studies, including five salient dichotomies (such as optimism versus pessimism) and two complex processes (posttraumatic growth and love). These case studies serve to highlight the type of critical, dialectical thinking that characterises this second wave, thereby outlining the contours of the evolving field.
Abstract: Mindfulness meditation has been purported to be a beneficial practice for wellbeing. It would therefore be expected that the neurophysiology of mindfulness would reflect this impact on wellbeing. However, investigations of the effects of mindfulness have generated mixed reports of increases, decreases, as well as no differences in EEG oscillations in comparison with a resting state and a variety of tasks. We have performed a systematic review of EEG studies of mindfulness meditation in order to determine any common effects and to identify factors which may impact on the effects. Databases were reviewed from 1966 to August 2015. Eligibility criteria included empirical quantitative analyses of mindfulness meditation practice and EEG measurements acquired in relation to practice. A total of 56 papers met the eligibility criteria and were included in the systematic review, consisting of a total 1715 subjects: 1358healthy individuals and 357 individuals with psychiatric diagnoses. Studies were principally examined for power outcomes in each bandwidth, in particular the power differentials between mindfulness and a control state, as well as outcomes relating to hemispheric asymmetry and event-related potentials. The systematic review revealed that mindfulness was most commonly associated with enhanced alpha and theta power as compared to an eyes closed resting state, although such outcomes were not uniformly reported. No consistent patterns were observed with respect to beta, delta and gamma bandwidths. In summary, mindfulness is associated with increased alpha and theta power in both healthy individuals and in patient groups. This co-presence of elevated alpha and theta may signify a state of relaxed alertness which is conducive to mental health.
Mindfulness meditation is thought to help practitioners become more tolerant of dysphoric emotions by enabling them to cultivate decentring skills. Such skills may be especially useful for male meditators, as men are thought to have particular difficulties regulating their emotions, partly due to masculinity norms around emotional toughness. However, there have been few studies pertaining to mindfulness focusing specifically on men, exploring the intersection between wellbeing and masculinity. Uniquely, we sought to examine the development of decentring capabilities in a non-clinical sample of male meditators using a longitudinal mixed-methods design. Thirty meditators were recruited in London, UK. Participants completed an emotional Stroop task – at two points, a year apart – to assess changes in emotional reactivity linked to meditation. Participants also undertook qualitative interviews at both time points, analysed using a modified constant comparison approach. Together, the two datasets converged to suggest that men did develop decentring skills through meditation, leading to greater equanimity in the presence of negative qualia. In addition to offering insights into the mechanisms underpinning the impact of mindfulness on wellbeing, the study provides a gendered dimension to the analysis of wellbeing strategies like meditation, a dimension which has hitherto been conspicuously absent from recent literature in fields such as positive psychology.
Organisations are increasingly concerned with promoting employee engagement. Research from positive psychology suggests that one key driver of engagement is experiencing work as meaningful. Organisations are therefore keen to understand how meaningful work is created. The present study conjectured that becoming a mentor might be one effective way of experiencing meaning at work. In-depth interviews were conducted with four experienced mentors, analysed using interpretative phenomenological analysis, to understand the impact that mentoring has on mentors. It was found that mentoring could indeed be a meaningful experience, enhancing work-related fulfilment. More detailed analysis revealed that meaning was engendered through a potent combination of self-determination (incorporating autonomy, relatedness and competence) and self-reflection, and a theoretical model was devised to reflect these findings. The paper offers recommendations for organisations, showing that mentoring relationships may not only benefit mentors (and mentees), but also organisations themselves.
