The aim of the current proposed study is to evaluate the effectiveness of MBCT in treating primary chronic insomnia in primary care by comparison with a psycho-education control (PEC) group. The research questions are as follows: 1. Can MBCT improve sleep efficiency, sleep latency, time awake after sleep onset and total sleep time in those who suffer from chronic insomnia when compared to a psycho-education control group? 2. Is MBCT effective in reducing health service utilization in patients with chronic insomnia (including utilization of primary care services e.g. private doctor consultation, Accident and Emergency utilization and general outpatient utilization) when compared to a psycho-education control group? We hypothesize that patients who have been randomized to the MBCT group would show greater improvements on sleep latency, time awake after sleep onset, and sleep efficiency when compared to a psycho-education control group. We also hypothesize that patients in the MBCT condition would have a greater reduction in health service use than patients in the psycho-education control group.
