BACKGROUND:Research suggests that an 8-week mindfulness-based cognitive therapy (MBCT) course may be effective for generalised anxiety disorder (GAD).
AIMS:
To compare changes in anxiety levels among participants with GAD randomly assigned to MBCT, cognitive-behavioural therapy-based psychoeducation and usual care.
METHOD:
In total, 182 participants with GAD were recruited (trial registration number: CUHK_CCT00267) and assigned to the three groups and followed for 5 months after baseline assessment with the two intervention groups followed for an additional 6 months. Primary outcomes were anxiety and worry levels.
RESULTS:
Linear mixed models demonstrated significant group × time interaction (F(4,148) = 5.10, P = 0.001) effects for decreased anxiety for both the intervention groups relative to usual care. Significant group × time interaction effects were observed for worry and depressive symptoms and mental health-related quality of life for the psychoeducation group only.
CONCLUSIONS:
These results suggest that both of the interventions appear to be superior to usual care for the reduction of anxiety symptoms.
