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 ...

Background: Aging is often characterized by cognitive impairment that sometimes exceed the expected for normal aging. These changes that do not meet criteria for dementia establish the cognitive impairment no dementia (CIND) that, regardless of etiology, has a high conversion rate to dementia. Aims: To investigate the effect of a Group Neuropsychological Rehabilitation Program (GNRP) in cognitive, executive and emotional functioning of institutionalized elderly with CIND. Methods: The sample included 24 elderly individuals, aged between 67 and 92 years. Twelve elderly underwent the GNRP and twelve elderly stayed on a waiting list. The study had a quasi-experimental design and was blind in the re-assessment. The ten interventions took 90 minutes per session, once a week. The pre and post-intervention assessment included the Montreal C...
