Background Generalized anxiety disorder (GAD) is one of the most common mental disorders; however, there is no brief clinical measure for assessing GAD. The objective of this study was to develop a brief self-report scale to identify probable cases of GAD and evaluate its reliability and validity. Methods A criterion-standard study was performed in 15 primary care clinics in the United States from November 2004 through June 2005. Of a total of 2740 adult patients completing a study questionnaire, 965 patients had a telephone interview with a mental health professional within 1 week. For criterion and construct validity, GAD self-report scale diagnoses were compared with independent diagnoses made by mental health professionals; functional status measures; disability days; and health care use. Results A 7-item anxiety scale (GAD-7) had good reliability, as well as criterion, construct, factorial, and procedural validity. A cut point was identified that optimized sensitivity (89%) and specificity (82%). Increasing scores on the scale were strongly associated with multiple domains of functional impairment (all 6 Medical Outcomes Study Short-Form General Health Survey scales and disability days). Although GAD and depression symptoms frequently co-occurred, factor analysis confirmed them as distinct dimensions. Moreover, GAD and depression symptoms had differing but independent effects on functional impairment and disability. There was good agreement between self-report and interviewer-administered versions of the scale. Conclusion The GAD-7 is a valid and efficient tool for screening for GAD and assessing its severity in clinical practice and research.

Psychometric properties of the Beck Depression Inventory: Twenty-five years of evaluation

Un nouvel inventaire auto-administre destine a mesurer l'anxiete pathologique, le «Beck Anxiety Cheklist» (BAI) est decrit, evalue et compare au «Hamilton Anxiety Rating Scale» (test avec lequel des correlations moderees sont trouvees)

An inventory for measuring clinical anxiety: psychometric properties.

The structure of negative emotional states: comparison of the Depression Anxiety Stress Scales (DASS) with the Beck Depression and Anxiety Inventories.

The amended (revised) Beck Depression Inventory (BDI-IA; Beck & Steer, 1993b) and the Beck Depression Inventory-II (BDI-II; Beck, Steer, & Brown, 1996) were self-administered to 140 psychiatric outpatients with various psychiatric disorders. The coefficient alphas of the BDI-IA and the BDI-II were, respectively, .89 and .91. The mean rating for Sadness on the BDI-IA was higher than it was on the BDI-II, but the mean ratings for Past Failure, Self-Dislike, Change in Sleeping Pattern, and Change in Appetite were higher on the BDI-II than they were on the BDI-IA. The mean BDI-II total score was approximately 2 points higher than it was for the BDI-IA, and the outpatients also endorsed approximately one more symptom on the BDI-II than they did on the BDI-IA. The correlations of BDI-IA and BDI-II total scores with sex, ethnicity, age, the diagnosis of a mood disorder, and the Beck Anxiety Inventory (Beck & Steer, 1993a) were within 1 point of each other for the same variables.

Comparison of Beck Depression Inventories -IA and -II in psychiatric outpatients.

The authors intensively studied 207 patients hospitalized because of suicidal ideation, but not for recent suicide attempts, at the time of admission. During a follow-up period of 5-1 0 years, 14 patients committed suicide. Of all the data collected at the time of hospitalization, only the Hopelessness Scale and the pessimism item of the Beck Depression Inventory predicted the eventual suicides. A score of 10 or more on the Hopelessness Scale correctly identified 91 % of the eventual suicides. Taken in conjunction with previous studies showing the relationship between hopelessness and suicidal intent, these findings indicate the importance of degree of hopelessness as an indicator of long-term suicidal risk in hospitalized depressed patients. (Am J Psychiatry 142:559-563, 1985)

Hopelessness and eventual suicide: a 10-year prospective study of patients hospitalized with suicidal ideation.

Studied internal consistencies of the 1961 and 1978 versions of the Beck Depression Inventory in two different samples of psychiatric patients. The alpha coefficient for the 598 inpatients and outpatients who were administered the 1961 version was 0.88, and the alpha coefficient for the 248 outpatients who were self-administered the 1978 version was 0.86. The patterns of corrected item-total correlations were also similar, and it was concluded that the internal consistencies of both versions were comparable.
