Introduction

Concomitant anxiety and insomnia is a frequent problem encountered by mental health professionals.

Primary objective

To assess the impact of cognitive-behavior therapy for insomnia (CBT-I) on associated anxiety.

Method

Systematic search for clinical trials of CBT-I in PsycInfo, Medline, and Proquest Dissertations and Theses.

Results

Of the 216 CBT-I trials reviewed, 72 (33.3 % ) reported data on anxiety. The combined effect size (ES) of CBT-I on anxiety was 0.406 [95 % CI 0.318–0.493], indicating a small to moderate effect of CBT-I on concomitant anxiety. Anxiety and anxiety-related constructs were measured with 31 different questionnaires or questionnaire subscales, the majority of which were used only once in the sample of studies.

Conclusions

CBT-I has only a moderate impact on anxiety in individuals who present insomnia with or without a comorbid anxiety disorder. A careful evaluation of residual anxiety should be conducted subsequent to CBT-I. Further research should focus on standardizing the assessment of anxiety in insomnia research.
