However, in view of ongoing research, changes in government regulations, and the constant flow of information relating to drug therapy and drug reactions, the reader is urged to check the package insert for each drug for any changes in indications and dosage and for added warnings and precautions.
Staging can be performed in a minimally invasive manner via endosonography including endobronchial ultrasonography (EBUS) and esophageal ultrasonography (EUS) with real-time aspiration of the lymph nodes [3,4,5].
Unlike surgical staging techniques such as mediastinoscopy, EBUS and EUS are minimally invasive and cost-effective.
The clarity and content validity of the questions were tested using a Delphi-like approach.
Construct validity was explored by administering the test to 3 groups with different levels of endosonography experience: 27 medical students, 18 respiratory physicians with limited endosonography experience, and 14 experts in endosonography.
The internal consistency reliability was calculated at 0.91.
The 3 groups performed significantly differently (ANOVA: p Received: January 06, 2014Accepted: April 04, 2014Published online: May 21, 2014 Issue release date: June 2014 Number of Print Pages: 7 Number of Figures: 2 Number of Tables: 1 ISSN: 0025-7931 (Print) e ISSN: 1423-0356 (Online) For additional information: https:// Copyright: All rights reserved.

This study was comprised of two parts: the development of MCQs and gathering of validity evidence (fig. Questions rated ‘1' by one or more members of the panel were excluded and questions with a mean rating of 4 or less were reevaluated until unanimity was reached.
