TL;DR: The Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision (DSM-IV-TR) (American Psychiatric Association], 2000) is a compendium of mental disorders, a listing of the criteria used to diagnose them, and a detailed system for their definition, organization, and classification.
Abstract: The Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision (DSM-IV-TR) (American Psychiatric Association [APA], 2000) is a compendium of mental disorders, a listing of the criteria used to diagnose them, and a detailed system for their definition, organization, and classification. Put simply, it is the primary diagnostic manual for mental health professionals in the United States and much of the Western world. Diagnosis refers to the identification and labeling of a mental disorder by examination and analysis. Mental health professionals diagnose individuals based on the symptoms that they report experiencing and the signs of illness with which they present. The DSM-IV-TR aids professionals in understanding and diagnosing mental disorders through its provision of explicit diagnostic criteria and an official classification system. Keywords: diagnosis; classification; mental illness; psychopathology

TL;DR: In this study, mating preference was achieved by dividing a population of Drosophila melanogaster and rearing one part on a molasses medium and the other on a starch medium and it was confirmed that symbiotic bacteria can influence mating preference by changing the levels of cuticular hydrocarbon sex pheromones.
Abstract: Development of mating preference is considered to be an early event in speciation. In this study, mating preference was achieved by dividing a population of Drosophila melanogaster and rearing one part on a molasses medium and the other on a starch medium. When the isolated populations were mixed, “molasses flies” preferred to mate with other molasses flies and “starch flies” preferred to mate with other starch flies. The mating preference appeared after only one generation and was maintained for at least 37 generations. Antibiotic treatment abolished mating preference, suggesting that the fly microbiota was responsible for the phenomenon. This was confirmed by infection experiments with microbiota obtained from the fly media (before antibiotic treatment) as well as with a mixed culture of Lactobacillus species and a pure culture of Lactobacillus plantarum isolated from starch flies. Analytical data suggest that symbiotic bacteria can influence mating preference by changing the levels of cuticular hydrocarbon sex pheromones. The results are discussed within the framework of the hologenome theory of evolution.

TL;DR: Results suggest that both the subjective subscale and total score on the BAI can be somewhat useful as a quick screening instrument in detecting presence of a current anxiety disorder for older adult psychiatric outpatients, although results were not as strong as previous findings regarding screening tests for depression in the elderly.

TL;DR: The Diagnostic Interview Schedule for DSM-IV (DIS-IV; Robins, Cottler, Bucholz, Compton, North, & Rourke, 2000) is a structured interview designed to diagnose in a reliable and valid fashion the major psychiatric disorders according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) (American Psychiatric Association, 2000).
Abstract: The Diagnostic Interview Schedule for DSM-IV (DIS-IV; Robins, Cottler, Bucholz, Compton, North, & Rourke, 2000) is a structured interview designed to diagnose in a reliable and valid fashion the major psychiatric disorders according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) (American Psychiatric Association, 2000). The DIS-IV is unique among the multidisorder structured diagnostic interviews in that it is a fully structured interview specifically designed for use by nonclinician interviewers, whereas the other interviews are semi-structured. By definition, a fully structured interview specifies clearly all questions and probes and does not permit deviations. Keywords: psychiatric diagnosis; structured interview; assessment

TL;DR: Suggestions for future research on the SCID are offered, particularly with respect to the lack of studies in which SCID diagnoses are compared with diagnoses from unstructured interviews or other structured-interview formats, and the need for a more natural evaluation of this instrument.

TL;DR: Results suggest the K-SADS-PL generates reliable and valid child psychiatric diagnoses.
Abstract: Objective To describe the psychometric properties of the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version (K-SADS-PL) interview, which surveys additional disorders not assessed in prior K-SADS, contains improved probes and anchor points, includes diagnosis-specific impairment ratings, generates DSM-III-R and DSM-IV diagnoses, and divides symptoms surveyed into a screening interview and five diagnostic supplements. Method Subjects were 55 psychiatric outpatients and 11 normal controls (aged 7 through 17 years). Both parents and children were used as informants. Concurrent validity of the screen criteria and the K-SADS-PL diagnoses was assessed against standard self-report scales. Interrater ( n = 15) and test-retest ( n = 20) reliability data were also collected (mean retest interval: 18 days; range: 2 to 38 days). Results Rating scale data support the concurrent validity of screens and K-SADS-PL diagnoses. Interrater agreement in scoring screens and diagnoses was high (range: 93% to 100%). Test-retest reliability κ coefficients were in the excellent range for present and/or lifetime diagnoses of major depression, any bipolar, generalized anxiety, conduct, and oppositional defiant disorder (.77 to 1.00) and in the good range for present diagnoses of posttraumatic stress disorder and attention-deficit hyperactivity disorder (.63 to .67). Conclusion Results suggest the K-SADS-PL generates reliable and valid child psychiatric diagnoses. J. Am. Acad. Child Adolesc. Psychiatry , 1997, 36(7): 980–988.

TL;DR: Prevalence and severity of health loss were weakly correlated and age-specific prevalence of YLDs increased with age in all regions and has decreased slightly from 1990 to 2010, but population growth and ageing have increased YLD numbers and crude rates over the past two decades.
