Although there are few Brazilian studies on this subject, envy is a universal phenomenon present in the cultural and social spheres. This research aimed to conduct a cross-cultural adaptation to Brazilian Portuguese and to evaluate validity evidence for the Benign and Malicious Envy Scale (BeMaS), a measure of benign and malicious envy. A total of 248 adolescents aged between 12 and 17 (M=13.93 ±1.39, 47.9% boys) participated in this research. Evidence of validity based on content, internal structure, relationship to other variables (stress, anxiety, depression, and life satisfaction), and reliability indicators were estimated. The exploratory factor analysis suggested the adequacy of the internal structure composed of two factors, demonstrating the equivalence of the internal structure with the original version and good indicators of reliability (ω= 0.760 e 0.823) and relationships with external variables consistent with the theoretical hypotheses. The Results suggest the adequacy of the instrument. [ABSTRACT FROM AUTHOR]

Objective: The Hierarchical Taxonomy of Psychopathology (HiTOP) posits that psychopathology is hierarchically structured. For personality disorder (PD) traits, there are five spectra: internalizing, thought disorder, disinhibited externalizing, antagonistic externalizing, and detachment. Empirical findings suggest a sixth group, compulsivity. In this research, we tried to recover the five HiTOP spectra, plus compulsivity, specifically for PD traits. Methods: The sample was composed of 4,868 Brazilians (54.9% women, age ranging from 18 to 70; mean = 25.7; SD = 9.64). All participants answered the Dimensional Clinical Personality Inventory 2 (IDCP-2), a self-report inventory for adults, developed in Brazil, for assessment of pathological personality traits. Results: Parallel analysis yielded up to nine factors. On exploratory structural equation modeling (E-SEM), the balance between interpretability and fit index suggested the six-factor solution as the best solution. The fit indexes for the confirmatory factor analysis were slightly less adjusted in comparison to the empirical model. Conclusion: The hypothesis was confirmed, as we did find the groups proposed at the spectrum level of the HiTOP. We also found a compulsivity factor, encompassing the main traits from the conscientiousness dimension of IDCP-2, which is related to obsessive-compulsive PD. Finding the six groupings of traits in the HiTOP model contributes to the validity of this model, and confirms the existence of proposed spectra. [ABSTRACT FROM AUTHOR]

This study analyzed the internal structure of the Brazilian version of the WISC-IV by comparing the composed scoring model with two other models: one based on a general factor of intelligence and another based on the CHC theory. The participants included 795 children and adolescents between the ages of 6 and 16 hailing from different regions of Brazil. The results indicated that the most suitable model was the one proposed in the manual. The model of the CHC theory also presented a good fit, but with values that was inferior to those of the original proposal. Moreover, the model of the general factor was rejected because the goodness-of-fit indices were not satisfactory. [ABSTRACT FROM AUTHOR]

The internal structure of three nests of Atta laevigata was studied in Botucatu city, São Paulo State, Brazil. Two nests were excavated through the opening of trenches and one was cement-moulded to enable a better view of the internal structures. The three nests presented a similar structure, with the depths and number of chambers varying as a function of the loose soil area of the nests. The number of chambers ranged from 1149 to 7864, reaching as deep as 7 m underground. Chamber volume ranged from 0.03 to 51 l. The foraging tunnels extended as far as 70 m from the loose soil region. The nests of this species are the deepest within the genus Atta and have the highest number of chambers. [ABSTRACT FROM AUTHOR]
