Quality of life and anxiety disorders: a population study.
ABSTRACT The study of quality of life has increased in importance in the area of mental disorders during the last decade. The aim of the present study was to investigate the effect of specific anxiety disorders on specific quality of life indicators in the common population. More than 2000 individuals between 18 and 65 years old were studied by means of structured interviews. The results showed that social phobia and panic disorder within the past year and lifetime, and generalized anxiety disorder within the past year, had an independent effect on quality of life when controlling for a number of sociodemographic variables, somatic health, and other DSM-III-R Axis I mental disorders. Specific phobias and obsessive compulsive disorder had only a small effect, and agoraphobia showed no effect. The effect was strongest for self-realization and contact with friends, but anxiety disorders also influenced subjective well-being, social support, negative life events, contact with family of origin, and neighborhood quality.

ABSTRACT: The aim of this study was to explore white-matter disruption in social anxiety disorder (SAD) patients by using diffusion tensor imaging (DTI) and to investigate the relationship between cerebral abnormalities and the severity of the symptoms. Eighteen SAD patients and age- and gender-matched healthy controls were recruited. DTI scans were performed to measure fractional anisotropy (FA) and apparent diffusion coefficient (ADC) for each subject. We used voxel-based analysis to determine the differences of FA and ADC values between the two groups with two-sample t-tests. The SAD patient showed significantly decreased FA values in the white matter of the left insula, left inferior frontal gyrus, left middle temporal gyrus, and left inferior parietal gyrus and increased ADC values in the left insula, bilateral inferior frontal gyrus, bilateral middle temporal gyrus, and left inferior parietal gyrus. In SAD patients, we observed a significant negative correlation between FA values in the left insula and the total LSAS scores and a positive correlation between the ADC values in the left inferior frontal gyrus and the total LSAS scores. Above results suggested that white-matter microstructural changes might contribute to the neuropathology of SAD.03/2014; 2014:860658. DOI:10.1155/2014/860658

ABSTRACT: Background. Anxiety disorders are associated with considerable disability in the domains of (1) work, (2) social, and (3) family and home interactions. Psychiatric comorbidity is also known to be associated with disability. Methods. Data from the Cross-National Collaborative Panic Study was used to identify rates of comorbid diagnoses, anxiety and depression symptom ratings, and Sheehan disability scale ratings from a clinical sample of 1165 adults with panic disorder. Results. Comorbid diagnoses of agoraphobia, major depression, and social phobia were associated with disability across the three domains of work, social, and family and home interactions. The symptom of agoraphobic avoidance makes the largest contribution to disability but there is no single symptom cluster that entirely predicts impairment and disability. Limitations. The findings about the relative contributions that comorbid diagnoses make to disability only apply to a population with panic disorder. Conclusions. Although panic disorder is not generally considered to be among the serious and persistent mental illnesses, when it is comorbid with other diagnoses, it is associated with considerable impairment. In particular, the presence of agoraphobic avoidance should alert the clinician to the likelihood of important functional impairment. When measuring the functional impact of comorbid anxiety disorders, both the categorical and the dimensional approaches to diagnosis make valuable contributions.03/2014; 2014:619727.

ABSTRACT: Objective: Although cognitive-behavioral therapy (CBT) is effective for treating anxiety disorders, little is known about its effect on quality of life. To conduct a meta-analysis of CBT for anxiety disorders on quality of life, we searched for relevant studies in PubMed, PsycINFO, and the Cochrane Library and conducted manual searches. Method: The search identified 44 studies that included 59 CBT trials, totaling 3,326 participants receiving CBT for anxiety disorders. We estimated the controlled and within-group random effects of the treatment changes on quality of life. Results: The pre-post within-group and controlled effect sizes were moderately strong (Hedges's g = 0.54 and Hedges's g = 0.56, respectively). Improvements were greater for physical and psychological domains of quality of life than for environmental and social domains. The overall effect sizes decreased with publication year and increased with treatment duration. Face-to-face treatments delivered individually and in groups produced significantly higher effect sizes than Internet-delivered treatments. Conclusion: CBT for anxiety disorders is moderately effective for improving quality of life, especially in physical and psychological domains. Internet-delivered treatments are less effective than face-to-face treatments in improving quality of life.
