Most of us care about our health (something we elves encourage) but for up to 5% of people, worrying about health has become a significant problem in itself. Severe health anxiety, or hypochondriasis, is said to exist when someone holds a strong fear of having a serious disease, despite all medical assurances to the contrary.
Mindfulness-based Cognitive Therapy (MBCT) involves an 8-week group programme using guided meditations that strengthen our ability to encounter mental and physical experiences directly, with a non-judgemental, moment-by-moment acceptance.
Given the increasing evidence base for MBCT as an effective treatment for depression, anxiety and stress (as blogged by The Mental Elf) it makes sense to consider its potential use for health anxiety.
In a study published in the Journal of Consulting and Clinical Psychology last year, researchers from the University of Oxford found preliminary support for the use of MBCT as a psychological approach alongside the usual package of care.
Using a randomised controlled trial design, the authors compared the difference in health anxiety indicators between participants who undertook an MBCT course while receiving treatment as usual (TAU), and those receiving TAU alone. The MBCT course was adapted slightly to focus on health anxiety.
The study looked at 68 participants whose health anxiety was measured prior to intervention, immediately following intervention and at a 1-year-follow-up.
All participants had to meet DSM-IV-TR criteria for health anxiety as their primary diagnosis. Sixty-five per cent were self-referred and 35% were referred by a health professional. The majority were female (78%) and white (97%).
A composite of three measures was used to assess levels of health anxiety: two standardised self-report measures for health anxiety, and a treatment-blind independent assessor rating. Changes in mindfulness was also measured, as were depression and anxiety levels.
Here’s what they found:
- Those in the MBCT group scored significantly lower on the health anxiety composite scores than the TAU group, both immediately following the intervention and at 1-year-follow-up
- Significantly fewer of the MBCT compared with the TAU group continued to meet diagnostic criteria for health anxiety at both post-intervention and 1-year-follow-up
- A mediation analysis showed that a change in mindfulness was responsible for these significant findings
- There was no significant difference between the two groups in levels of depression and anxiety at either assessment period
The authors concluded that:
…this trial provides reason for optimism that the effects of MBCT are mediated by change in the mechanisms hypothesized to underlie it and that MBCT has potential as an adjunctive class-based psychological approach to treating severe health anxiety.
- The small sample size and high percentage of white, female, highly educated participants in the study highlights the need for caution in generalising the findings across the greater population of people diagnosed with health anxiety.
- Self-referral was the predominant route for participant recruitment in response to advertisement (33.8%) or GP-suggestion (31.1%); so the study cannot be said to have investigated MBCT in a routine clinical practice setting.
- The MBCT group was compared to TAU, rather than a directly comparable psychological treatment, matching for treatment period and therapist input levels.
Despite these limitations, the positive findings should be taken as preliminary clinical support that mindfulness-based therapies show promise as a treatment for health anxiety, and that further research resolving the above limitations is well worthwhile.
As something of an aside, the finding that depression and anxiety scores did not significantly differ between groups was also really interesting, given previous research (Hofmann et al, 2010 for review). Although this could have been a result of lower power to detect differences in these symptoms compared with health anxiety, it certainly raises an interesting question about the scope of tailoring mindfulness programmes to specific conditions, and whether this will be to the detriment of wider benefits to mental health.
