Purpose: The aim of this study was to validate the Social Appeal Scale (SAS) among the Spanish general population, exploring the underlying dimensions of the construct assessed.
Materials and methods: The SAS test was applied to 555 participants between 16 and 75 years of age. The scale is divided into four dimensions: social competence (SC), intellectual ability (IA), psychologic adjustment (PA), and relationship satisfaction (RS).
Results: The SAS (12 items) had a Cronbach alpha of .93, and SC had a Cronbach alpha of .83. For IA it was .85, for PA .87, and for RS .84.
Conclusion: Bearing in mind the limitations of the present study, it may be concluded that the Social Appeal Scale is a valid and reliable instrument to assess social perceptions related to changes in tooth color.
