Abstract
Background/Objective The evaluation of depression requires valid and reliable measuring instruments, which collect a wide spectrum of symptoms that this disorder displays, in order to carry out an accurate and differential diagnosis. The objective of this work is the construction of the Depression Clinical Evaluation Test (DCET), where affective, somatic, cognitive, behavioral and interpersonal symptoms are considered and also analyze its content validity through an expert judgment. Method Based on different diagnostic and manual classifications, a specification table for a depression test was established. In its evaluation, 16 experts in Psychological Assessment, Psychometry and/or Psychopathology participated. A total of 300 items were created. The experts had to assess the items according to the criteria of Content, Relevance, Clarity, Comprehension, Sensitivity, and Offensiveness. In addition, 50 adults, evaluated the compression of the items. Results The degree of understanding for all the items was high and the expert judgment favoured the suppression of 104 items, thus obtaining a shorter measuring instrument with a total of 196 items for ease of application. Conclusions The content validity of the test is adequate and fits the agreed definition of depression.
