Un pilote avec groupe témoin : effets de la méditation de pleine conscience sur la qualité de vie, le sommeil et l’humeur chez des adolescents atteints de cancer

L’annonce d’un diagnostic de cancer provoque souvent une forte réaction émotionnelle et un stress important tant chez les adultes que chez les adolescents et leurs parents. Certains d’entre eux cherchant à soulager cette détresse se tournent vers des méthodes alternatives positives de gestion de stress, dans le but d’atténuer les effets psychologiques indésirables du cancer. Les thérapies ciblant à la fois le corps et l’esprit gagnent en popularité dans ces populations. Une avenue prometteuse est la méditation de pleine conscience (MPC), inspirée de la philosophie bouddhiste et adaptée dans le cadre d’interventions thérapeutiques pour améliorer la qualité de vie des patients souffrant de maladies chroniques. À ce jour, des études dans le domaine de la santé ont suggéré que la MPC pouvait avoir des effets bénéfiques sur les symptômes et la gestion de plusieurs maladies chroniques dont le cancer, faisant d’elle une avenue thérapeutique intéressante dans le traitement des effets psychologiques indésirables liés à ces maladies. La recherche émergente en pédiatrie suggère des effets comparables chez les enfants et adolescents. L’objectif de la présente thèse a été de développer un essai clinique randomisé visant à évaluer les effets de la MPC sur la qualité de vie, le sommeil et l’humeur chez des adolescents atteints de cancer, en documentant les étapes d’implantation du projet, les embuches qui ont été rencontrées durant son implantation et les résultats obtenus. La thèse est présentée sous la forme de deux articles scientifiques. Le premier article présente la méthodologie qui avait été planifiée pour ce projet mais qui n’a pu être réalisée en raison d’embuches rencontrées dans la complétion de ce pilote. Ainsi, les étapes préliminaires du développement de ce projet de recherche, en accordant une place prépondérante au manuel d’intervention rédigé à cette fin. La mise en place et la structure de ce projet, nommément le devis méthodologique employé, la taille d’échantillon visée, les méthodes de recrutement mises en place et les stratégies de randomisation prévues, sont décrites en détail dans cet article. Pour les fins de ce projet, un manuel d’intervention de MPC a été rédigé. L’intervention en MPC, menée par deux instructeurs formés en MPC, s’est échelonnée sur une durée de huit semaines, à raison d’une séance d’une heure trente par semaine. Une description détaillée de chaque séance est incluse dans cet article, dans un but de dissémination du protocole de recherche. Des analyses intragroupe serviront à évaluer l’impact de l’intervention en méditation de pleine conscience sur la qualité de vie, le sommeil et l’humeur pré-à-post intervention et au suivi à six mois. Des analyses intergroupes prévues sont décrites afin de comparer les effets de l’intervention entre les participants du groupe contrôle et du groupe expérimental. Les limites potentielles de ce projet, notamment la participation volontaire, le risque d’attrition et la petite taille d’échantillon sont décrites en détail dans cet article. Le deuxième article présente, dans un premier temps, le déroulement du projet de recherche, en mettant en lumière les embuches rencontrées dans son implantation. Ainsi, les leçons à tirer de l’implantation d’un tel essai clinique en milieu hospitalier au Québec sont décrites selon trois axes : 1) les défis liés au recrutement et à la rétention des participants; 2) l’acceptabilité et la compréhensibilité de l’intervention en pleine conscience; et 3) le moment où l’intervention s’est déroulée (timing) et l’impact sur l’engagement requis des participants dans le projet. Durant une période de recrutement de neuf mois, 481 participants potentiels ont été filtrés. 418 (86,9 %) d’entre eux ont été exclus. 63 participants potentiels, vivant à moins d’une heure de Montréal, ont été approchés pour prendre part à ce projet. De ce nombre, seulement 7 participants (1,4%) ont accepté de participer aux rencontres de MPC et de compléter les mesures pré-post intervention. Un bassin d’éligibilité réduit, ainsi que des taux de refus élevés et des conflits d’horaire avec les activités scolaires ont eu un impact considérable sur la taille d’échantillon de ce projet et sur l’absentéisme des participants. Malgré l’intérêt manifeste des équipes médicales pour la recherche psychosociale, les ressources requises pour mener à terme de tels essais cliniques sont trop souvent sous- estimées. Les stratégies de recrutement et de rétention des participants méritent une attention spéciale des chercheurs dans ce domaine. Dans un deuxième temps, le deuxième article de cette thèse a pour objectif de présenter les résultats de l’intervention en MPC chez des jeunes ayant le cancer, en examinant spécifiquement l’impact de l’intervention sur la qualité de vie, le sommeil et l’humeur des jeunes pré-post intervention et lors du suivi à six mois. Faisant écho aux embuches décrites préalablement décrites, les analyses statistiques n’ont permis de déceler aucun effet statistiquement significatif de notre intervention. Aucune différence significative n’est notée entre les participants du groupe expérimental et les participants du groupe contrôle. Les difficultés rencontrées dans de la complétion des devoirs et de la pratique de techniques de méditation entre les séances, décrites en détail cet article, expliquent en partie ces résultats. Globalement, le contexte développemental spécifique à l’adolescence, ayant possiblement eu un impact sur l’adhérence des participants à la thérapie proposée et à leur motivation à prendre part aux rencontres, les scores sous-cliniques lors du premier temps de mesure, l’impact du soutien social inhérent au contexte de thérapie de groupe, ainsi que les caractéristiques personnelles des thérapeutes, pourraient avoir influencé les résultats de ce pilote. Les résultats de ce projet pilote nous laissent croire que la prudence est de mise dans la généralisation des bienfaits et de l’efficacité de la pleine conscience observés chez les adultes atteints de cancer dans son application aux adolescents en oncologie. En conclusion, la présente thèse contribue à enrichir la recherche dans le domaine de la MPC chez les jeunes en questionnant néanmoins la pertinence d’une telle intervention auprès d’une population d’adolescents souffrant de cancer. Ainsi, il convient d’analyser les résultats obtenus en tenant compte des limites méthodologiques de ce projet et de poser un regard critique sur la faisabilité et la reproductibilité d’un projet d’une telle envergure auprès d’une même population. Les leçons tirées de l’implantation d’un tel projet en milieu hospitalier pédiatrique se sont avérées d’une importance centrale dans sa complétion et feront partie intégrante de toute tentative de réplication. D’autres essais cliniques de cette nature seront inévitablement requis afin de statuer sur l’efficacité de la MPC chez des adolescents atteints cancer et sur la faisabilité de l’implantation de cette méthode d’intervention auprès d’une population pédiatrique hospitalière.

Mindfulness-meditation on the move : implementation of an ACT-based mindfulness practice intervention and training within a University Dance program

As part of the introduction of a broader dance medicine and science related health and wellbeing program, a 9 week mindfulness-meditation ACT-based program was delivered to all students undertaking full-time University dance training (N = 106). The aim of the program was to assist students in the further development of performance psychology skills that could be applied in both performance and non-performance settings. Participant groups were comprised of both male (N = 12) and female (N = 94) students from across all three year levels of two undergraduate dance courses, divided into three groups by mixed year levels due to timetable scheduling requirements. Pre- and post-testing was undertaken utilising the Mindful Attention Awareness Scale (MAAS-15), a uni-dimensional measure of mindfulness, in addition to qualitative questions checking the current level of awareness and understanding of mindfulness practice and its application. Weekly sessions were conducted by qualified sport and exercise psychologists and covered key practices such as: Mindfulness of Body, Mindfulness of Breathing, Mindfulness of Sounds, ACT-based and general Imagery exercises, Developing Open Awareness, Mindfulness of Emotions, and Developing Inner Stillness. Students were required to maintain a reflective journal that was utilised at the end of each weekly session, in addition to completion of a mid-Semester reflective debrief. Teaching staff additionally attended the weekly sessions and linked the mindfulness practice learnings into the student’s practical dance and academic classes where appropriate. Anecdotal feedback indicates that participation in the mindfulness-meditation sessions and the development of these mental skills has resulted in positive performance and personal outcomes. Observations collated from staff and students, results from the data collection phases and recommendations regarding future applications within dance training settings will be discussed within the presentation.

New Ways of Being a Man: “Positive” Hegemonic Masculinity in Meditation-based Communities of Practice

Connell’s concept of hegemonic masculinity is often reduced to a singular construct, consisting of “toxic” traits viewed as detrimental to well-being. However, the concept allows for variation in hegemony, including the possibility of forms more conducive to well-being. Through in-depth interviews with thirty male meditators in the United Kingdom, we explored the social dimensions of meditation practice to examine its potential implications for well-being. Most participants became involved with “communities of practice” centered on meditation that promoted new local hegemonies, and these included ideals experienced as conducive to well-being, like abstinence. However, social processes associated with hegemony, like hierarchy and marginalization, were not overturned. Moreover, participants faced challenges enacting new practices in relation to the broader system of hegemonic masculinity—outside these communities—reporting censure. Our findings are cautionary for professionals seeking to encourage well-being behaviors: that is, there is potential for adaptation in men, yet complex social processes influence this change.

Effect of mobile phone-based psychotherapy in suicide prevention : a randomized controlled trial in Sri Lanka

We conducted a randomized controlled trial to test whether a Brief Mobile Treatment (BMT) intervention could improve outcomes relative to usual care among suicide attempters. The intervention included training in problem solving therapy, meditation, a brief intervention to increase social support as well as advice on alcohol and other drugs, and mobile phone follow-up. The effect of the intervention was measured in terms of a reduction in suicidal ideation, depression and self-harm at Baseline, six and 12 months. A wait-list control group received usual care. A total of 68 participants was recruited from a Sri Lankan hospital following a suicide attempt. Participants who received the intervention were found to achieve significant improvements in reducing suicidal ideation and depression than those receiving usual care. The BMT group also experienced a significant improvement of social support when compared to the control group. However, the BMT group did not demonstrate a significant effect in reducing actual self-harm and most substance use, and differential effects on alcohol use were restricted to men. Although the present study was limited in revealing which component of the intervention was more effective in preventing suicide, it showed its efficacy in reducing suicide as a whole.

Review and evaluation of mindfulness-based iPhone apps

Background There is growing evidence for the positive impact of mindfulness on wellbeing. Mindfulness-based mobile apps may have potential as an alternative delivery medium for training. While there are hundreds of such apps, there is little information on their quality. Objective This study aimed to conduct a systematic review of mindfulness-based iPhone mobile apps and to evaluate their quality using a recently-developed expert rating scale, the Mobile Application Rating Scale (MARS). It also aimed to describe features of selected high-quality mindfulness apps. Methods A search for “mindfulness” was conducted in iTunes and Google Apps Marketplace. Apps that provided mindfulness training and education were included. Those containing only reminders, timers or guided meditation tracks were excluded. An expert rater reviewed and rated app quality using the MARS engagement, functionality, visual aesthetics, information quality and subjective quality subscales. A second rater provided MARS ratings on 30% of the apps for inter-rater reliability purposes. Results The “mindfulness” search identified 700 apps. However, 94 were duplicates, 6 were not accessible and 40 were not in English. Of the remaining 560, 23 apps met inclusion criteria and were reviewed. The median MARS score was 3.2 (out of 5.0), which exceeded the minimum acceptable score (3.0). The Headspace app had the highest average score (4.0), followed by Smiling Mind (3.7), iMindfulness (3.5) and Mindfulness Daily (3.5). There was a high level of inter-rater reliability between the two MARS raters. Conclusions Though many apps claim to be mindfulness-related, most were guided meditation apps, timers, or reminders. Very few had high ratings on the MARS subscales of visual aesthetics, engagement, functionality or information quality. Little evidence is available on the efficacy of the apps in developing mindfulness.

A Review of Meditation in the Irish Construction Industry: Critical Success Factors in Competencies and Processes

The construction industry notoriously excels at dispute creation – both in Ireland and world wide. This paper exams mediation in the Irish construction industry based around critical success factors in the competencies and processes required by mediators operating in the construction industry. Through conducting the relevant analysis, it was possible to extract and outline the resulting critical success factors in process and competencies of mediators in the Irish construction industry. This was achieved through a review of the literature, followed by detailed interviews from industry experts to elicit and highlight the core competencies required. To aid in the study, qualitative analysis using mind mapping software was adopted, thus assisting the identification of the key factors. Following analysis, facilitative mediation was identified as best suited for the industry in question; recommendations and experience were key for mediator selection and five and six factors were identified for mediator skills and mediation critical success factors respectively. The results returned are similar to those determined by authors in other countries and provide a good reference point for the development the industry. By following the findings of this report mediators and parties in dispute can improve processes and be more successful in outcomes. In this study the author shows that mediation is an effective and appropriate method of resolving disputes within the Irish construction industry.

‘To me, it's like a little box of tricks’: Breaking the depressive interlock as a programme participant in mindfulness-based cognitive therapy

Objectives. Mindfulness meditation practices have become increasingly popular in clinical therapies, changing patterns of depressogenic thinking for individuals who experience consecutive episodes of depression. We were interested in finding out how Mindfulness Based Cognitive Therapy (MBCT) worked for programme participants by focussing on how meditative practices changed their relationships to their thoughts. Design. Data for the study came from six semi-structured research interviews carried out with individuals who had taken part in an 8 week MBCT programme Methods. We used Interpretative Phenomenological Analysis (IPA) to analyse the experiential accounts. Results. We report on two superordinate themes – Engaging the Neutral Mind (with subordinate themes ‘breaking the paralysis of worry’ and ‘choosing to think differently’) and Experiencing the Neutral Mind (with subordinate themes of ‘reflection on previous thinking styles’ and ‘becoming psychologically self-reliant’). Conclusions. Themes from the present study offer support to the assertion that mindfulness meditation helps facilitate a different mode of meta-cognitive processing with which to handle depression-related cognitions. Practitioner Points Participants reported that they experienced an enhanced capacity to differentiate between their thought processes, experiencing an ability to tolerate some more uncomfortable thoughts and experiencing a/more choice in how to respond to thoughts Participants recognised that ruminating over negative thoughts was related to depressive states and experienced a shift in meta-cognitive processes that actively challenged depressogenic cognitions Participants became more psychologically self-reliant and therapeutically independent following MBCT Integrating mindfulness based practices in therapy may be a mediating factor in sustaining psychological wellbeing and may help clients develop self-compassion Future research looks to examining exit cases to understand elements of MBCT which are experienced as less successful by clients

The Impact of Mindfulness Meditation on Educator Growth and Professional Development: A Personal Account

This study examined the use of mindfulness meditation in educator growth and professional development. The purpose was to create recommendations for an effective mindfulness meditation practice for educators. To this end, as the researcher is an educator as well as an experienced mindfulness meditation practitioner, the research methodology was self-study through narrative inquiry. The exploration of mindfulness meditation on the researcher’s personal and professional development was viewed through the lenses of Maslow’s hierarchy of needs and Mezirow’s transformational learning theory. These theories provided an analytical framework that guided this research. Themes were drawn from the exploration and connected with academic literature. The results were a mindfulness meditation framework for educators that is based on the Socratic Method, and utilizes the conceptual frameworks of Maslow’s hierarchy of needs and Mezirow’s transformational learning theory.

The tonglen experiences of individuals with established sitting meditation practices: a grounded theory study

While there is an ever expanding body of research on various forms of meditation, there is currently a relative absence of academic literature on tonglen. A form of meditation which involves both visualizations and breathing elements, during tonglen one takes in the negativity and suffering experienced by others and, in return, sends back happiness and compassion. The current study explores the tonglen meditation experiences of individuals who have established sitting meditation practices. A qualitative, grounded theory approach was used in looking at what tonglen means to participants, how they engage with the practice, why they practice tonglen, and what they perceive to be the benefits of tonglen in the context of a 28 day practice period. Based on the findings from this study, a model was developed that describes the tonglen experiences of participants.

The Role of Home Practice Engagement in a Mindfulness-Based Intervention

Over the last three decades, there has been a precipitous rise in curiosity regarding the clinical use of mindfulness meditation for the self-management of a broad range of chronic health conditions. Despite the ever-growing body of evidence supporting the use of mindfulness-based therapies for both medical and psychological concerns, data on the active ingredients of these mind-body interventions are relatively scarce. Regular engagement in formal mindfulness practice is considered by many to be requisite for generating therapeutic change; however, previous investigations of at-home practice in MBIs have produced mixed results. The equivocal nature of these findings has been attributed to significant methodological limitations, including the lack of standardized, systematic practice monitoring tools, and a singular focus on practice time, with little attention paid to the nature and quality of one’s practice. The present study used a prospective, observational design to assess the effects of home-based practice on dispositional mindfulness, self-compassion, and psychological functioning in twenty-eight people enrolled in an MBSR or MBCT program. To address some of the aforementioned limitations, the present study collected detailed weekly accounts of participants’ home-based practice engagement, including information about practice time (i.e., frequency and duration), exercise type, perceived effort and barriers to participation, and practice quality. Hierarchical multiple regression was used to examine the relative contribution of practice time and practice quality on treatment outcomes, and to explore possible predictors of adherence to at-home practice recommendations. As anticipated, practice quality and perceived effort improved with time; however, rather unexpectedly, practice quality was not a significant predictor of treatment-related improvements in psychological health. Home practice engagement, however, was predictive of change in dispositional mindfulness, in the expected direction. Results of our secondary analyses demonstrated that employment status was predictive of home practice engagement, with those who were unemployed completing more at-home practice on average. Mindfulness self-efficacy at baseline and previous experience with meditation or other contemplative practices were independently predictive of mean practice quality. The results of this study suggest that home practice helps generate meaningful change in dispositional mindfulness, which is purportedly a key mechanism of action in mindfulness-based interventions.
