MERINO-SOTO, César. Confidence interval for difference between coefficients of content validity (Aiken's V): a SPSS syntax. Anal. Psicol. [online]. 2018, vol.34, n.3, pp.587-590. ISSN 1695-2294.  https://dx.doi.org/10.6018/analesps.34.3.283481.

Analysis of content validity usually includes measures to summarize the ratings of expert judges. However, differences between groups of judges have not been previously raised, and it is plausible that these differences occur. The present manuscript raises the comparison between-groups of the coefficient V (Aiken, 1980), as a strategy that must be implemented in the analysis of the content validity. We present a method based on the construction of confidence intervals for the difference between coefficients V, for two independent groups. Finally, a free SPSS syntax is also included.
