Sleep disturbance is one of the key diagnostic criteria for generalized anxiety disorder (GAD). In this cross-sectional, prospective, observational, and multicenter study, factors associated with the prevalence of insomnia and the impact of insomnia-associated factors on quality of life were evaluated. Using multivariate analyses, the factor most strongly associated with the presence of insomnia (ISI ≥ 8) was the severity of the disorder (Odds Ratio [OR]: 9.253 for severe GAD; 95% Confidence Interval [CI]: 1.914-44.730; p = 0.006), pain interference and symptoms of depression (OR: 1.018; 95% CI 1.003-1.033; p = 0.016 and OR: 1.059; 95% CI 1.019-1.101; p = 0.004, respectively). Insomnia was not related to quality of life. Our results show insomnia to be a common health condition among patients with GAD, associated with the severity of anxiety and depressive symptoms and pain interference.
