In the first issue of the Portuguese Journal of Behavioral and Social Research, the importance of calculating, indicating, and interpreting the effect sizes for the differences of means of two groups (d family of effect sizes) was reviewed. Effect sizes are standard metrics that allows the comparison of the results of statistical analyzes of different studies. Effect sizes also report on the impact of a factor on the variable under investigation and the association between variables.After reviewing the effect sizes for the mean differences between two groups (Espirito-Santo & Daniel, 2015) and most of the r family (Espirito-Santo & Daniel, 2017), the review of effect sizes for analysis of variance was lacking. Analysis of variance can be understood as an extension of the d family to more than two groups (ANOVA) or as an r subfamily in ...

Background: The progressive increase in the prevalence of anxiety disorders in advanced ages advises the extensive use of screening inventories in this population that, everywhere in the world, has become increasingly numerically significant. Goals: The aim of this study is to present the results of validation and reliability studies of the Portuguese version of Geriatric Anxiety Inventory (GAI). Methods: After, translation and back-translation of GAI, the Portuguese version was administered to 805 institutionalized elderly. The reliability of the scale was assessed by Cronbach's alpha coefficient and factorial validity using the extraction method of Principal Components Analysis. The convergent validity study was conducted with the Geriatric Depression Scale and the Negative Affects Schedule while discriminant validity was performed ...
