What are the Active Ingredients of Mindfulness-based Interventions?

active 1

Mindfulness-based interventions typically comprise numerous elements, including some or all of the following: guided mindfulness exercises, guided loving-kindness and compassion meditation exercises, group discussion, psycho-education (sometimes in the style of a university lecture), yoga, one-to-one discussion with the programme facilitator, a CD of guided meditations to encourage at-home practice, and a full or half-day silent group retreat. Given that each of the above techniques arguably have therapeutic utility in their own right, ascertaining why MBIs are effective is problematic because they have numerous ‘active ingredients’.

Not controlling for other active ingredients is a common limitation of MBI intervention studies. Indeed, although scientific evidence demonstrates that certain MBIs are equally or more effective than other treatments for improving specific health conditions, it is currently unclear whether it is mindfulness, or mindfulness in combination with other therapeutic techniques, that results in health benefits. One way to overcome this methodological limitation is to employ a purpose-designed ‘active’ control condition. This is a control intervention that mirrors the main intervention in terms of its design, but does not include any mindfulness techniques. By conducting a randomised controlled trial that compares the effectiveness of an MBI against a suitably formulated active control intervention, we can determine that superior outcomes in the MBI versus control group are caused by mindfulness.

It could be argued that it doesn’t matter whether it is specifically mindfulness or other intervention components that make MBIs effective. If we are only interested in treatment outcomes and adhere to a ‘what works’ approach to alleviating illness symptoms, then establishing which intervention components are most effective becomes less important. However, from the point of view of advancing scientific understanding of how the human mind reacts to given psychotherapeutic techniques, it is useful to establish which ingredients are most active within a given intervention. Such knowledge can also help to inform the development of more effective and ‘therapeutically streamlined’ MBIs.

When designing an active control intervention for MBI efficacy studies, in addition to matching the design of the target and control interventions (i.e., minus the inclusion of mindfulness techniques), it is also important to match the ‘competency’ of the instructor or instructors delivering the two interventions. For example, a number of meditation intervention studies employing an active control condition have used an experienced clinician and meditation teacher to deliver the MBI, whilst leaving a relatively inexperienced student to administer the control intervention. Clearly, such an approach can introduce bias and weaken the strength of the evidence from MBI studies.

In order to overcome the above methodological limitation, in a recent randomised controlled trial that we conducted, the study was designed such that the same instructor delivered the MBI and comparison intervention. To control for potential bias on the part of the instructor, participants in each intervention condition were asked to rate the instructor’s levels of enthusiasm and preparation. Statistical tests were then performed to determine if there were significant differences between how participants from the intervention and control group rated the instructor’s performance.

We decided to control for an ‘instructor effect’ because in our opinion, the mindfulness instructor is one of the most active ingredients in MBIs. Part of our research has involved the development and empirical investigation of a ‘second-generation’ of MBI. Second-generation MBIs (such as Meditation Awareness Training) are designed slightly differently compared to ‘first-generation’ MBIs (such as Mindfulness-based Stress Reduction or Mindfulness-based Cognitive Therapy). More specifically, second generation MBIs are overtly spiritual in nature and teach a greater range of meditative techniques. Given that second-generation MBIs comprise different design elements compared to first-generation MBIs, it is reasonable to assume that these two types of MBIs will result in different outcomes. However, despite the design differences between first- and second-generation MBIs, it is our view that if a mindfulness teacher with authentic spiritual realisation was to administer a first-generation MBI, the outcomes would be very similar to them administering a second-generation MBI.

In other words, if the mindfulness teacher is genuinely rooted in the present moment, the specific design of the MBI becomes less important. As we discussed in our post on The Four Types of Psychologist, we would argue that the same principle applies to the majority of psychological therapies. If the clinician knows their own mind, has genuine compassion for the client, and is skilled in helping the client understand their problems, then the choice of therapy becomes less important.

Although preliminary findings (including from some of our own clinical case studies and qualitative studies) support the notion that the mindfulness teacher is one of the (if not the) most important ingredients of MBIs, there is clearly a need for further research investigating how the instructor influences outcomes. However, in the absence of extensive empirical investigation into this subject, we hypothesise that what participants of MBIs need most (and therefore respond best to), is the unconditional love and spiritual wisdom of a teacher who is without a personal agenda, and whose mind is saturated with meditative awareness.

Does Mindfulness Have a Role in the Treatment of Fibromyalgia Syndrome?

Does Mindfulness Have a Role in the Treatment of Fibromyalgia Syndrome?

Fibro 1

Fibromyalgia syndrome is a poorly understood chronic pain disorder. An estimated 3% of adults are reported to suffer from fibromyalgia, with higher levels of occurrence in females compared to males. The main symptoms of fibromyalgia syndrome are all-over body pain, tiredness, difficulty in sleeping, and cognitive dysfunction such as memory impairment. There is also a high level of association between fibromyalgia syndrome and poor quality of life, mental health issues such as depression and anxiety, irritable bowel syndrome, and unemployment.

Some of the reasons why fibromyalgia syndrome is believed to be a controversial illness are as follows:

  1. Individuals with fibromyalgia are reported to exert a higher burden upon healthcare resources when compared with individuals diagnosed with other chronic illnesses.
  1. Research has shown that individuals with fibromyalgia often experience difficulty in having their illness diagnosed, and often feel that their needs and symptoms are poorly understood by the medical profession.
  1. A diagnosis of fibromyalgia is primarily based upon the exclusion of other illnesses, the patient’s medical history, and their reaction to pressure being gently applied to ‘tender points’. In other words, there isn’t a reliable laboratory test for fibromyalgia syndrome (e.g., blood test, x-ray) and this means that it is difficult to be 100% certain that a given individual is genuinely suffering from the illness.

The current treatment-of-choice for fibromyalgia syndrome is the use of psychopharmacology (principally antidepressants) coupled with non-pharmacological approaches such as physical exercise, cognitive-behavioural therapy, self-help, and/or psycho-education. However, pharmacological treatments for fibromyalgia have shown only a limited degree of effectiveness, and many patients withdraw from treatment due to the side-effects of antidepressants as well as low levels of symptom reduction.

The lack of convincing treatment efficacy outcomes for existing pharmacological and non-pharmacological fibromyalgia interventions has led to the empirical evaluation of alternative treatment approaches. Since there exists evidence (which varies in quality and quantity) supporting the use of mindfulness in treating each of the individual symptoms of fibromyalgia syndrome (e.g., chronic pain, sleep disturbance, fatigue, depression, anxiety, and cognitive dysfunction), mindfulness-based interventions have been an obvious candidate in terms of investigating their effectiveness for treating the illness.

A systematic review and meta-analysis comprising six randomised and non-randomised controlled trials of mindfulness-based stress reduction (MBSR) for individuals with fibromyalgia (674 participants in total) found that individuals receiving MBSR experienced significant short-term improvements in quality of life and pain compared to individuals in the non-meditating control groups. A further systematic review (incorporating a range of intervention study designs) examined the findings from ten studies of mindfulness meditation (702 participants in total). The review concluded that mindfulness led to significant improvements in both physical symptoms (e.g., pain, sleep quality, functionality) and psychological symptoms (e.g. depression, anxiety, perceived helplessness).

In terms of the possible mechanisms by which mindfulness helps to alleviate the symptoms of fibromyalgia syndrome, the most widely proposed explanation is that mindfulness helps to increase perceptual distance from somatic pain and distressing psychological stimuli. By mindfully observing painful bodily sensations, it appears that individuals suffering from fibromyalgia (and other pain disorders) can begin to objectify and almost distance themselves from their pain. The same applies to feelings of psychological distress and fatigue that are often associated with musculoskeletal pain. Mindfully observing feelings of distress, frustration and low mood appears to weaken the intensity of such feelings, and to help create the ‘psychological space’ necessary for other – more psychologically adaptive – feelings and thought processes to arise.

Based on findings from a randomised controlled trial of an online mindfulness-based intervention, it has been suggested that stronger treatment outcomes can actually be achieved by using mindfulness not just as a means of improving patient’s ability to cope with pain and psychological distress, but as a means of helping improve patients’ ability to engage in effective social and interpersonal interactions. In other words, given the complexity of fibromyalgia syndrome, it appears that in order to maximise treatment effectiveness, mindfulness interventions targeting fibromyalgia should be purpose-designed and encourage participants to draw on both psychological and social resources.

In terms of other potential mechanisms of action, there is evidence to suggest that mindfulness leads to changes in neurological pain pathways, reduced levels of ruminative thinking and self-preoccupation, and improvements in spirituality. This latter potential mechanism is important because cross-sectional studies involving individuals with fibromyalgia have specifically identified a positive correlation between spirituality and positive affect (i.e., as levels of spirituality increase so do positive mood states), and a negative association between spirituality and symptoms of depression and anxiety (i.e., as levels of spirituality increase in individuals with fibromyalgia, their levels of depression and anxiety decrease).

Findings indicate that purpose-designed mindfulness-based interventions may have a role to play in the treatment of fibromyalgia syndrome. However, at present the overall quality of the evidence is weak and there is a need to replicate and consolidate findings using methodologically robust randomised controlled trials.
