简要总结
The study is a three-arm intervention, where students are randomly assigned to one of three conditions: Teacher-led group-based MBCT, Self-guided MBCT using an audio book, or 'wait list' control. Pre-intervention, respondents complete a questionnaire assessing self, values, psychological processes related to self, and well-being. Post-intervention, respondents complete the same questionnaire, and then take part in a laboratory-based study which assesses behaviours related to the variables measured in the questionnaires. We are aiming for a sample size of 180 students at Sussex, 60 in each intervention arm.
详细描述
Substantive evidence shows that mindfulness training improves mental health and general well-being (see meta-analyses by Cavanagh, Strauss, and colleagues). A significant factor that reduces well-being is the internalisation of two core consumer culture values: a materialistic value orientation (MVO) and body perfect ideals (see meta-analyses by Dittmar and colleagues for MVO, and Grabe et al, Barlett et al. for idealised media models). Thus, mindfulness may act as a buffer against the negative impact of consumer culture ideals, consistent with value circumplex models which place materialistic and appearance-focused values at the self-enhancement end, opposite to self-transcendence values, such as caring for self and others and community engagement.
Self-transcendence values lead to psychological need satisfaction, whereas consumer culture values undermine such satisfaction (Self-Determination Theory).
Three novel questions are examined: (1) Is change in self-related values and psychological processes significant for the beneficial consequences of mindfulness for well-being? (2) Does mindfulness training reduce consumer culture values and associated harmful behaviours, such as disordered eating and excessive buying? (3) Do high and low intensity mindfulness interventions differ in impact?
The project involves collaboration with Kate Cavanagh in Psychology and the Co-Directors of the Sussex Centre for Mindfulness Clara Strauss and Robert Marx. It consists of: 1. qualitative interviews with experienced mindfulness teachers, 2. a multi-phase student intervention study, and 3. an exposure experiment with the same student sample.
Study 1: INTERVIEWS WITH MINDFULNESS TEACHERS (n=12) Semi-structured interviews with teachers (recruited through the UK Network of Mindfulness Teacher Training Organisations) will examine their views on the psychological processes significant in individuals' mental health improvement, focusing on processes related to values and self. Interviews will be audio-taped.

研究组 & 干预措施
Teacher-led MBCT course
Eight-session mindfulness-based cognitive therapy course, including an initial orientation session, led by a qualified mindfulness teacher working with the Sussex Mindfulness Centre, a part of the NHS Sussex Partnership Mental Health Trust.
干预措施: Teacher-led MBCT course (Other)
Self-guided MBCT course
Mindfulness-based cognitive therapy course, after an initial information session, which is self-guided using the audiobook Mindfulness: A practical guide to finding peace in a frantic world by Mark Williams and Danny Penman (2011). It consists of eight substantive chapters that map on to the eight-session MBCT course taught by teachers to groups of students. Students will be asked to work through one chapter a week, thus matching the pace of the teacher-led intervention.
干预措施: Self-guided MBCT course (Other)
Wait list control
Students in the wait list (control) arm do not receive any intervention for the same length of time as the experimental and active comparator arms of the intervention are taking place. Students are invited to complete the self-guided MBCT course after the end of the research project.
结局指标
主要结局
Indicators of psychological well-being: Change in Mental health
时间窗: The change in this self-report measure will be be measured by being collected five-six weeks before the intervention, and immediately after the intervention
We are using a mental health assessment (DASS-21) widely used in clinical and non-clinical populations which assess symptoms of depression, anxiety, and stress
Indicators of psychological well-being: Change in Subjective well-being
时间窗: The change in this self-report measure will be be measured by being collected five-six weeks before the intervention, and immediately after the intervention
This measure consists of an assessment of life satisfaction, and a brief measure of the frequency of positive and negative affective experiences as used in (Dittmar and Kapur, 2011)
Indicators of psychological well-being: Change in consumption-based coping
时间窗: The change in this self-report measure will be be measured by beingcollected five-six weeks before the intervention, and immediately after the intervention
This is a newly developed scale which measures the extent to which individuals use buying material goods as a strategy to cope with stress (Wright et. al, 2016)
Indicators of psychological well-being: Change in body esteem
时间窗: The change in this self-report measure will be be measured by being collected five-six weeks before the intervention, and immediately after the intervention
We are using a well-established scale of body esteem (Mendelson et al., 2001), which assesses general appearance evaluation, evaluation of one's weight, and perceived evaluation by others
Indicators of psychological well-being: Change in eating behaviour
时间窗: The change in this self-report measure will be be measured by being collected five-six weeks before the intervention, and immediately after the intervention
We will use a shortened form of the Dutch Eating Behaviour Scale (Van Strien et al., 1986) which measures restraint, emotional, and external eating
Indicators of psychological well-being: Change in material esteem
时间窗: The change in this self-report measure will be be measured by being collected five-six weeks before the intervention, and immediately after the intervention
This is a newly developed scale that assesses individuals' esteem in terms of the material goods they own (Dittmar et al., 2016)
Indicators of psychological well-being: Change in excessive buying
时间窗: The change in this self-report measure will be be measured by being collected five-six weeks before the intervention, and immediately after the intervention
This scale measures compulsive buying tendencies, such as having urges to buy or feeling out of control of one's shopping behaviour (Dittmar et al., 2007)
Indicators of psychological well-being: Change in emotional regulation
时间窗: The change in this self-report measure will be be measured by being collected five-six weeks before the intervention, and immediately after the intervention
This scale, developed by Bjureberg (2016), assessing difficulties that people experience in dealing with, and regulating strong emotions
次要结局
- Behavioural measure related to consumer culture: buying consumer goods online(This behavioural measure will be collected immediately after exposure to consumer culture stimuli in phase 4 of the research)
- Consumer culture values (materialistic and appearance-focused personal values)(This self-report measure will be collected five-six weeks before the intervention, immediately after the intervention, and immediately after exposure to consumer culture stimuli in phase 4 of the research)
- Behavioural measure related to consumer culture: eating(This behavioural measure will be collected immediately after exposure to consumer culture stimuli in phase 4 of the research)
