Integration of insomnia management strategies in cognitive behavior therapy for generalized anxiety disorder - 16/09/20
Abstract |
The objective of this study was to evaluate the impact of integrating insomnia management strategies into CBT for GAD on insomnia and anxiety. Forty-nine participants with GAD (84% females; mean age=32.0) were randomized to 12-weeks of CBT for GAD that included or excluded insomnia management strategies. Participants completed the Anxiety Disorders Interview Schedule for DSM-IV (ADIS-IV) before and after treatment, as well as the Insomnia Severity Index (ISI) and the Worry and Anxiety Questionnaire (WAQ) before and after treatment and at 3- and 6-month follow-ups. There was no condition effect and no condition×time interaction effect on the primary outcomes (ISI and WAQ). Both conditions produced large decreases in insomnia, F(3, 46.03)=25.75, P<0.001, pre- to post-treatment g=1.03, 95% CI [0.69–1.37] and anxiety, F(3, 45.93)=37.32, P<0.001, from pre- to post-treatment g=1.23, 95% CI [0.86–1.59]. The proportion of participants with baseline insomnia disorder who no longer had this condition post-treatment was larger in CBT GAD+Insomnia (89%) than in CBT GAD (59%), X2(1)=4.23,=0.040. CBT for GAD alone may improve insomnia symptoms, and the integrated treatment did not show additional benefits on the insomnia severity outcome. However, the addition of insomnia management strategies may be of greatest benefit for individuals with insomnia disorder.
