mindfulness meditation practice 2–3 times per week.
Finding the time to practice and lack of group support
were highlighted as obstacles to on-going practice. The
lack of ongoing support was a common theme, and we
would suggest that the establishment of ongoing support
groups may be a very important part of long-term effectiveness.
Does an 8-week course result in improved mood as
measured on Beck Depression Inventory (BDI-II) and Beck
The mean pre-course depression score was 35.7 and post
course was 17.8. A similar reduction was noted for anxiety
with a mean pre-course anxiety score of 32.0 and mean
post course of 20.5. Overall 8/11 patients (72%) showed
improvements in BDI and 7/11 (63%) patients showed
improvements in BAI with pre/post effect sizes of 1.5 for
reduction in depression and 0.77 for anxiety. While the
numbers involved in this study are small, the results compare favourably with results published using other group
psychotherapies. In one uncontrolled study using a 12- week group CBT programme for the combined treatment
of depression and anxiety, the authors report that 69% of
the patients had an improvement in BDI and 62% an
improvement in BAI . Pre/post effect sizes for depression and anxiety in this study were 0.9 and 0.44 respectively.
Although post-course depression and anxiety scores (BDI
and BAI) showed statistically significant improvements in
mood and the majority of the participants believed they
had benefited from the course, it is worth highlighting
that 5 of the 11 patients continued to have significant levels of depression and or anxiety three months later (moderate to severe range). Two of these five patients reported
that they found the course beneficial despite no improvement in BDI and a worsening post-course BAI. The other
three patients' BDI or BAI scores moved from the severe
range to moderate range. These findings are consistent
with results from a meta-analysis on the efficacy of group
psychotherapy for depression, whi...
