| Abstract | OBJECTIVE: To reduce false positive diagnoses, DSM-IV added a clinical significance criterion to many diagnostic criteria sets requiring that symptoms cause significant distress or impairment. The DSM-V Task Force is considering whether clinical significance should remain a diagnostic threshold or become a separate dimension, as it is in ICD. Yet, the criterion's effectiveness in validly reducing the prevalence of specific disorders remains unclear. Critics have argued that for some categories, notably major depression, the criterion is redundant with symptoms, which are inherently distressing or impairing. The authors empirically evaluated the criterion's effect on the prevalence of major depression in the community. This report also considers more broadly the relationship of symptoms to impairment in diagnosis. METHOD: Subjects were respondents, aged 18 to 54 years, who participated in the National Comorbidity Survey Replication (N=6,707). The effect of the clinical significance criterion's distress and impairment components on major depression was assessed in this sample. Distress questions were administered to all respondents reporting persistent sadness (> or = 2 weeks) or the equivalent. Questions pertaining to role impairment were asked of all respondents satisfying major depression symptom-duration criteria. RESULTS: Of 2,071 individuals reporting persistent sadness or the equivalent, 97.2% (N=2,016) satisfied criteria for distress. Of 1,542 individuals satisfying depression symptom-duration criteria, 96.2% (N=1,487) satisfied criteria for impairment. CONCLUSIONS: These findings support the redundancy thesis. Distress is virtually redundant with symptoms of persistent sadness, even in the absence of major depression, and impairment is almost always entailed by major depression-level symptoms. Thus, the clinical significance criterion does not substantially reduce the prevalence of major depression in the community. The DSM-V Task Force should consider eliminating the criterion and explore alternative ways to identify false positives in the diagnosis of depression. The criterion's status for other disorders should be evaluated on a disorder-by-disorder basis because the diagnostic relationship between symptoms and impairment varies across categories. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
