The authors investigated whether the psychological benefits and meditation practice identified three months after attending a Mindfulness-Based Cognitive Therapy (MBCT) program were maintained in a group of mental health professionals at 18-months follow-up. Of the 23 participants who attended the original MBCT program, 18 agreed to participate. A repeated measures design was employed with the following measures taken: mindfulness; psychological well-being; life satisfaction; trait worry; trait and state anxiety; and an index of weekly meditation practice. A measure of life events and perceived stress (SRRS) was also included. Participants (N = 10) who provided data at each of the three time-points -baseline, 3-months followup and 18-months follow-up -were included in the repeated measures ANOVAs.Compared to baseline, a significant improvement in levels of mindfulness, trait anxiety and trait worry, was noted at 18-months follow-up. Three quarters of the current sample maintained some form of meditation practice although weekly amounts of meditation practice were found to be unrelated to psychological wellbeing. Contrary to prediction, life events and related levels of perceived stress correlated positively with levels of mindfulness. Attending an MBCT group as a mental health professional appears to have a positive impact on psychological wellbeing and ongoing meditation practice which persists long after the end of the intervention. Reasons for a lack of association between length of weekly practice and psychological well-being, as well as the positive relationship between perceived stress and mindfulness, are discussed.
