Abstract
The purpose of this instrumental study was to show how to conduct
a study aimed at obtaining content validity evidence in the test construction/adaptation
process. An applied perspective was used, and this paper presents the content validity
analysis of the Spanish adaptation of the State-Trait Cheerfulness Inventory trait form
(STCI-T). This paper illustrates the stages required to analyze content validity: 1)
definition of the content domain to be assessed, 2) item construction, and 3) expert
judgment of the items constructed. This study focused mainly on the third stage and
the results obtained with a previously selected panel of experts are included. The paper
briefly describes the most important criteria to consider in the selection of experts, the
procedure recommended to obtain judgments, the material to administer, aspects of
items to assess, and the type of analyses that should be conducted. Based on the
results obtained for the Spanish adaptation of the STCI-T, the article discusses the
importance of obtaining content validity evidence in the test construction/adaptation
process. The indices used demonstrated good content validity for the Spanish version
of the STCI-T.
