Evidence supports reliability and validity of the GAD-7 as a measure of anxiety in the general population. The normative data provided in this study can be used to compare a subject's GAD-7 score with those determined from a general population reference group.

The Toronto-Alexithymia-Scale (TAS-20) is used worldwide as a valid measurement of alexithymia. Until now, population-based standardization and cut-off values of the German TAS-20 version have not been available. This study provides these by means of a representative German sample and by investigating the factorial structure of the TAS-20. Data were generated from a representative random sample of the German general population (1,859 subjects aged between 20 and 69). The TAS-20 sum score was normally distributed. The mean value was 49.5 (SD=9.3) in men and 48.2 (SD=9.2) in women. Divorce, single and low social status were associated with enhanced sum scores. Ten percent of the population exceeded the TAS-20 sum score threshold of >or=61. The 66th percentile reached 53 for men and 52 for women. Factor analysis identified three factors that match the scales of the English original version. An additional fourth factor ("importance of emotional introspection") was extracted. Total explanation of variance by these four factors was 52.27%. The sum score of the German TAS-20 version is suited for the standardized measure of alexithymia. For selecting alexithymic individuals in experimental studies, the cut-off >or=61 is possibly too restrictive. Therefore, we propose the 66th percentile for the identification of high alexithymics. The TAS-20 sum score is associated with important socio-demographic variables. The factorial structure is reliable; the fourth factor ("importance of emotional introspection") provides differentiation of content and allows for enhanced explanation of variance.

Patients with AI on current standard replacement suffer from significantly impaired health-related subjective health status, irrespective of origin of disease or concomitant disease. Future studies will have to assess whether more physiological glucocorticoid replacement strategies in AI will ameliorate these impairments.

SummaryContext Recent studies suggest that current glucocorticoid replacement therapies fail to completely restore well-being in patients with adrenal insufficiency (AI). Objective The objective of this study was to investigate healthrelated quality of life (QoL) in patients with AI depending on dose and frequency of daily intake of hydrocortisone (HC). Design and patients In a cross-sectional study, primary and secondary AI patients were contacted and asked to complete three validated self-assessment questionnaires , Giessen Complaint List (GBB-24), Hospital Anxiety and Depression Scale (HADS)]. HC doses were corrected for body surface area. Results were compared with sex-and age-matched controls drawn from the questionnaire-specific reference cohort. Results Completed questionnaire sets were available from 334 patients on HC (primary AI n = 194; secondary AI n = 140). Patients on higher doses of HC (>30 mg/day) showed significantly impaired subjective health status in two of eight SF-36 dimensions, and three of five GBB-24 scales compared with those on lower HC doses. No significant differences in QoL were found between lower HC doses (15-30 mg/day) or between primary or secondary AI. Patients on HC with thrice daily intake showed significantly impaired QoL in one of eight SF-36 dimensions (15-20 mg/day, 20-25 mg/day), in one of five GBB-24 scales (15-20 mg/day), as well as higher anxiety scores. Conclusions Health-related QoL was impaired in patients with primary and secondary AI. HC doses above 30 mg/day were associated with a worse health status. Thrice daily intake of HC was not superior to twice daily intake. Our data support the perception that current replacement strategies are still insufficient to fully restore well-being and daily performance.

Depressive and anxiety symptoms as two psychological variables have an additional impact on domain-specific life satisfaction. Further investigation is needed regarding the impact of psychological variables on domain-specific life satisfaction.
