Efficacy of Cognitive Behavioral Treatment for Insomnia: A Randomized Controlled Trial.

This study examined the effects of cognitive behavioral treatment for insomnia. A randomized controlled trial was performed on 44 women. The intervention included one group session of sleep hygiene education and four individual sessions of counseling. The instruments included the Insomnia Severity Index, Pittsburgh Sleep Quality Index, the Center for Epidemiological Studies Depression Scale, and Menopausal quality of life. The data were analyzed using repeated measure MANOVA, followed by repeated measure ANOVA. Repeated measure MANOVA showed that time had a significant main effect on the anthropometric variables (body mass index, waist circumference, and blood pressures) and revealed significant main effects of the group and time on the psychosocial variables (sleep quality, insomnia, depressive symptoms, and quality of life) (p < .05). Repeated measure ANOVA results indicated a significant effect of the group on insomnia and sleep quality (p < .05). Overall, the intervention was effective in improving insomnia and poor sleep quality.
