TL;DR: Evidence supports reliability and validity of the G AD-7 as a measure of anxiety in the general population and can be used to compare a subject's GAD-7 score with those determined from a general population reference group.
Abstract: Background:The 7-item Generalized Anxiety Disorder Scale (GAD-7) is a practical self-report anxiety questionnaire that proved valid in primary care. However, the GAD-7 was not yet validated in the general population and thus far, normative data are not available.Objectives:To investigate reliability

TL;DR: The ability of the PHQ-9 to detect depression outcome and changes over time is demonstrated in three groups of patients whose depression status either improved, remained unchanged, or deteriorated over time.

TL;DR: All three questionnaires performed well in depression screening, but significant differences in criterion validity existed; these results may be helpful in the selection of questionnaires and cut-off points.

TL;DR: Recommendations for a stepped care approach that differentiates between uncomplicated and complicated FSS are given, and a balance between biomedical, organ-oriented, and cognitive interpersonal approaches is most appropriate at this truly psychosomatic interface.

TL;DR: Recovery is still possible for anorexic patients after a period of 21 years, but patients can relapse, becoming symptomatic again despite previously achieving recovery status, therefore, it is recommended that these patients should be monitored regularly and offered treatment whenever possible.
Abstract: Background. Given our poor understanding of the very long-term course of anorexia nervosa, many questions remain regarding the potential for recovery and relapse. The purpose of the present study was to investigate long-term outcome and prognosis in an anorexic sample 21 years after the initial treatment. Method. A multidimensional and prospective design was used to assess outcome in 84 patients 9 years after a previous follow-up and 21 years after admission. Among the 70 living patients, the follow-up rate was 90%. Causes of death for the deceased patients were obtained through the attending physician. Predictors of a poor outcome at the 21-year follow-up were selected based on the results of a previous 12-year follow-up of these patients. Results. Fifty-one per cent of the patients were found to be fully recovered at follow-up, 21% were partially recovered and 10% still met full diagnostic criteria for anorexia nervosa. Sixteen per cent were deceased, due to causes related to anorexia nervosa. The standardized mortality rate was 9·8. The three groups also showed significant differences in psychosocial outcome. A low body mass index and a greater severity of social and psychological problems were identified as predictors of a poor outcome. Conclusions. Recovery is still possible for anorexic patients after a period of 21 years. On the other hand, patients can relapse, becoming symptomatic again despite previously achieving recovery status. Only a few patients classified as having a poor outcome were found to seek any form of treatment, therefore, it is recommended that these patients should be monitored regularly and offered treatment whenever possible.

TL;DR: In this article, a 7-item anxiety scale (GAD-7) had good reliability, as well as criterion, construct, factorial, and procedural validity, and increasing scores on the scale were strongly associated with multiple domains of functional impairment.
Abstract: 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.
