A comparative analysis in content validity studies Susana Sanduvete-Chaves Salvador Chacón-Moscoso Milagrosa Sánchez-Martín José Antonio Pérez-Gil Psicología Comparison Rating Scales Osterlind Index Content Validity Empirical Evidence A procedure commonly used to obtain empirical evidence in content validity studies is the calculation of the Osterlind index after gathering the expert opinions about the adequacy of the items to measure a particular dimension of the tool. The aim of this work is to compare the results obtained when experts score the degree of suitability item-dimension on the traditional 3-point rating scales with the results obtained using, alternatively, 5-point ones. 105 participants valued, on 5-point rating scales, the fitness item-dimension of 31 items to 7 dimensions that composed a questionnaire to measure satisfaction with the training received. These marks were also transformed into 3-point rating scales. Comparison between Osterlind indexes calculated using scores from 5 and 3-point rating scales shows that the new propose is more conservative than the classic procedure; i.e., items considered adequate using 3-point rating scales were removed using 5-point rating scales. 2013 artículo científico 1578-908X https://www.redalyc.org/articulo.oa?id=344033718007 en http://www.redalyc.org/revista.oa?id=3440 Acción Psicológica application/pdf Universidad Nacional de Educación a Distancia Acción Psicológica (España) Num.2 Vol.10 |
