Abstract:
Objective:To study the effect of cognitive behavioral therapy on insomnia (CBT-i) for patients with insomnia and patients with comorbid depressive disorder.Methods:According to the score of Beck Depression Inventory (BDI), 71 patients who met the diagnosis of insomnia were divided into the insomnia group (<14 points, 33 cases) and the insomnia with depression group (≥14 points, 38 cases). Patients in both groups filled in sleep diaries every day and were given standard CBT-i treatment for 8 weeks. Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), BDI, Beck Anxiety Inventory (BAI), and the SF-36 Health Survey were evaluated before treatment (baseline), at 4 weeks, 8 weeks, 4 weeks after treatment (3 months), and 16 weeks after treatment (6 months). Independent sample t test was utilized to compare difference between two groups, while repeated measures ANOVA was adopted to analyze data at different timepoints. Results:Compared with baseline assessment, both insomnia group and insomnia with depression group showed significant differences in Sleep Onset Latency (SOL), Sleep Efficiency (SE), PSQI, ISI, BDI, BAI, and SF-36. There were no significant difference between the two groups, at baseline, 8 weeks, 3 months and 6 months in SOL, and SE, however, significant difference was found in the scores of BAI ( t=-6.340,-3.301,-3.511,-2.982), and SF-36 ( t=4.162,3.195,2.022,3.629; P<0.01 or 0.05). In the meantime, there was a significant difference on PSQI and ISI at 8 weeks and 3 months, while there was no significant difference of them at month 6 (7.3±4.6 vs. 4.7±3.4, t=-2.044, P=0.048) . There were no statistically significant differences in sleep latency, sleep efficiency and PSQI scores between the insomnia group and the insomnia with depression group at 8 weeks, 3 months and 6 months. However, compared with baseline measurement, the two groups showed statistically significant differences on BAI and BDI scores at week 8, month 3 and month 6 (all P<0.01). Conclusions:CBT-i is effective for patients with insomnia as well as those with comorbid depression, it could be helpful to alleviate the depressive symptoms and improve patient′s quality of life.
