Neuropsychology of generalized anxiety disorders: a systematic review
Abstract
The present study aimed to provide a comprehensive review of psycho-education in adults with formally
diagnosed anxiety disorders, assessing its effectiveness in reducing the severity of anxiety symptoms, psychological
distress, depression and pain, and improving quality of life and satisfaction with treatment. A systematic search was
conducted using a narrative approach for extraction and synthesis of the data. Searches were undertaken between
April and May 2017 in the following databases: Scopus, PubMed, Web of Science and Cochrane Central Register of
Controlled Trials (CENTRAL). The studies included had been published between 2000 and 2017. 2804 references
were identified, but the final sample of this review only considered five studies involving 490 participants. Three of the
studies used a randomized design. Most of the interventions used a face-to-face format. In addition, the internet and
the telephone were delivery resources used in available interventions addressed to anxiety disorders. All intervention
protocols included an educational component and anxiety symptom control skills. Psycho-education improved the
psychological distress, pain and quality of life of the patients with anxiety disorders and these effects remained over
time. The interventions and therapists received a good evaluation. However, we emphasize the need to develop more
research with sophisticated design to test the effect of psycho-educational interventions in this setting.
