RESUMO
INTRODUCTION: The Morphee Sleep network runs a short group CBT programme. During the pandemic, the programme was administered by videoconference. The programme focuses on behavioral modification. The objective of our study was to evaluate whether the videoconference programme produced changes in dysfunctional beliefs about sleep and whether these changes were linked to improvements in insomnia. METHODS: Observational study of 3×90minute sessions of group CBT by videoconference over one month delivered by experienced psychologists. The outcome measures : insomnia severity scale (ISI), dysfunctional beliefs and attitudes about sleep short version (DBAS 16), hospital anxiety and depression scale (subscales depression HADD and anxiety HADA), and epworth sleepiness scale (ESS) completed before session 1 and at the end of session 3. The effectiveness of the programme on insomnia was evaluated by the decrease in the ISI score : full response R+ (>7 points), partial response, R- (4 - 6 points) non response, NR (<3 points). The effect on dysfunctional beliefs and attitudes about sleep were measured by the decrease in the DBAS 16 with response CR (>9 points) and no response CNR (<9 points). RESULTS: There were fifty-five participants, 64 % women with a mean age of 49.1±16.1 years. The DBAS 16 was reduced by 6.12±1.29 to 5.09±1.57 (P< 0.0001) with 67 % of participants showing a response CR. The ISI score reduced from 17.7±3.6 to 14.0±4.9 (P< 0.0001) with 49 % showing at least a partial response (R+ and R-). A significant correlation (0.327, P=0.015) between the CBT response and dysfunctional beliefs about sleep was observed with a significant reduction in the DBAS 16 between responders R+ and non-responders (R+ vs. NR 1.67±1.3 vs. 0.57±1.28 P=0.012). Seventy-nine of R+ showed improvements in the DBAS 16 vs. 69 % of R- and 61 % of non-responders NR. CONCLUSION: A short group CBT programme by videoconference focused on behavioral modification can reduce dysfunctional beliefs about sleep.

OBJECTIVES: To evaluate the effectiveness of a short (3 session) programme of group cognitive behavioural therapy (CBT) on insomnia, sleepiness and symptoms of anxiety and depression. METHODS: Prospective observational study of group CBT with follow-up at 3 months. Participants were self-referred patients with chronic insomnia. Outcome measures were the insomnia severity scale (ISI), the Epworth sleepiness scale (ESS), depression (Pichot scale), and the number of anxiety symptoms. RESULTS: Participation in CBT was offered to 489 patients of whom 474 completed the programme and 154 were followed up at 3 months. Significant improvements in insomnia were seen: ISI score (17.74-14.27, P<0.0001) after CBT and at follow-up (13.78, P<0.0001). At the end of CBT, 76% (59/78) with initial severe insomnia and 52% (132/255) with moderate insomnia were improved, maintained at 3 months in 71% (15/21) with severe insomnia and 56% (50/90) with moderate insomnia. Depression and anxiety symptoms were significantly improved: mean depression symptoms (4.15-3.35, P<0.0001) and anxiety symptoms (4.52-3.95, P<0.0001), maintained at 3 months with mean depression symptoms (3.17, P<0.0001) and mean anxiety symptoms (3.62, P<0.0001). Sleepiness increased between baseline and the end of the group (6.67-7.24, P=0.015) followed by a reduction at 3 months (7.19-6.34 at 3 months, P=0.001). Initial ISI score but neither sex nor age were predictive of outcome. CONCLUSIONS: A short programme of CBT can improve sleep, depression and anxiety symptoms in self-referred patients suffering from chronic insomnia with good adherence and maximum benefit in patients with severe insomnia.
