  Author(s): Carlos Siordia Carlos Siordia
  
  The Center for Epidemiologic Studies Depression Scale (CES-D) is a widely used screening test for depression symptomatology in population studies. Publications have dealt with the psychometric properties of the instrument. Until now, no published work has examined the how questionnaire items are handled in data processing protocols. This technical report introduces the “CESD-Flag” macro algorithm using SAS® 9.3 syntax. The main contribution of the statistical program in this report is to provide data managers with a program that creates five CES-D flag variables to help identify the level and location of missingness in CES-D related data. The paper highlights implications from how data editing algorithms handle missing or inconclusive responses to CES-D questions. If absolute transparency should be encouraged as a desirable goal, then the methodology used to “cle.. View More»
