Participants were a nationwide sample of 3020 subjects aged 18---91 years old, from 22 different Brazilian states. Exploratory factor analysis supported a two-factor solution (presence of meaning - MLQ-P; and search for meaning --- MLQ-S). Adequate reliability indexes were achieved. Confirmatory factor analyses (CFA) provided evidence that the MLQ-P and MLQ-S scales present better goodness-of- fit indexes when evaluated separately. Multiple group CFA achieved full measurement and structural invariance for gender and age (youngsters, adults and the elderly) groups. Group comparisons were conducted for evaluating gender, age and marital status differences in both MLQ-P and MLQ-S scales. The results are presented and discussed based on the literature. Our results suggest that the MLQ is a reliable measurement to evaluate presence and search for meaning in life in the Brazilian population in a wide variety of age groups.

Participants were 730 subjects (65% women), aged from 17 to 70 years old (M = 31.0 years; SD = 11.43), from 21 Brazilian states. The sample was randomly split in two halves to cross-validate the results. With the first half of the sample (n1 = 365), an exploratory factor analysis (EFA) was conducted. With the second half of the sample (n2 = 365), a confi rmatory factor analysis (CFA) assessed the fit of the exploratory model. Convergent validity and group differences were also evaluated. The EFA and CFA presented a one-dimensional structure for the P-Scale. Moderate correlations were found between the P-Scale and mental-health, subjective happiness and life-satisfaction. The levels of positivity presented a low positive correlation with age, educational level and financial income. Slightly significant effects were found for occupational status and marital status. Positivity appears to be more closely related to personal dispositions than to sociodemographic aspects. Our results suggest that the P-Scale is a reliable measure with which to evaluate the levels of positivity in Brazil.

Because there is no consensus in the literature about its steps, this article discuss some essential aspects regarding the cross-cultural adaptation of psychological instruments and proposes guidelines to the researchers about the different steps of this process. Some considerations regarding the validation of the adapted instrument are also presented. In this stage, we discuss some aspects regarding the factorial structure of the instrument, which might be evaluated through statistical procedures, such as exploratory and confirmatory factor analysis. More than that, the authors provide some guidelines to the validation of psychological instruments in different cultures.

Participants were 587 Italian elementary school children, aged 7-10 years (51.5% female). Exploratory and confi rmatory factor analyses presented a one-factor solution for the PA scale and a three-factor solution for the RPA scale (reactive aggression, seeking teacher support and internalizing reaction), presenting adequate reliability and goodness-of-fi t indexes for both scales. Criterion validity presented satisfactory evidence. The PARB-Q appears to be a psychometrically sound tool to evaluate aggressive behavior and reactions to peer aggression in elementary school children.

However, weighting costs and benefits of using one specific model over alternative models depends on empirical information that is not always clearly available. Therefore, the aim of this simulation study was to compare the performance of seven popular statistical models in providing adequate latent trait estimates in conditions of items difficulties targeted at the sample mean or at the tails of the latent trait distribution. Results suggested an overall tendency of models to provide more accurate estimates of true latent scores when using items targeted at the sample mean of the latent trait distribution. Rating Scale Model, Graded Response Model, and Weighted Least Squares Mean- and Variance-adjusted Confi rmatory Factor Analysis yielded the most reliable latent trait estimates, even when applied to inadequate items for the sample distribution of the latent variable. These findings have important implications concerning some popular methodological practices in Psychology and related areas.

Participants were 3020 subjects (63.9% women), ranging in age from 18 to 91 years old (M = 33.92; SD = 15.01), sampled from 22 Brazilian states. Confirmatory factor analyses (CFA) supported the unidimensionality of MLQ-Presence scale, but suggested that two distinct latent variables explained the items of SoMe-Meaningfulness scale. This result was further supported by a bi-factor exploratory structural equation modeling, which showed that items 4 and 5 of the SoMe-Meaningfulness scale were primarily influenced by a second latent trait rather than by MIL. Further analyses showed that this second latent trait was more closely related with self-transcendence issues (generativity and spirituality, specifically) instead of MIL.

In this study, we sought to examine in a large Brazilian sample (N = 3,034 subjects, from 22 Brazilian states) the plausibility of existence of these categories and how people inserted on them would differ in terms of sociodemographic variables and psychological functioning (engagement with sources of meaning and scores on a set of dispositional and well-being constructs). Our results showed the existence of all four categories of meaning. Men were more frequently classified into the existentially indifferent and crisis of meaning groups. The meaningfulness group presented higher scores in all sources of meaning when compared to other groups, whereas the existentially indifferent group presented the lowest scores. A highly diverse pattern of relationships between the sources of meaning and the levels of meaningfulness for the different categories of meaning was found. Significant differences between the existential indifference and the existential conflict groups were found for subjective happiness, life satisfaction and self-esteem but not found for optimism, pessimism, hope (agency and pathways), and self-efficacy.

Participants were 524 subjects (69.8% women), aged from 18 to 88 years old (M = 38.3; SD = 13.26), from 17 Brazilian states. Exploratory and confi rmatory factor analyses supported a single-factor solution. Reliability was assessed using alpha reliability, average variance extracted and composite reliability. Convergent validity was presented using the MHI-5, the Subjective Happiness Scale, the Satisfaction with Life Scale, and the General Health Questionnaire (GHQ-12). Discriminant validity, using the GHQ-12, showed that MHI-5 is a reliable measure to evaluate mental health. The scale presented strong evidence of validity and seems appropriate to evaluate mental health in the Brazilian population.

Participants were 3.034 subjects (63.9% women), ranging in age from 18 to 91 years. Reliability analysis, parallel analysis (PA), exploratory structural equation modeling (ESEM) and confirmatory factor analyses (CFA) were employed to evaluate the structure and reliability of the SoMe-BR. Through PA and ESEM, a five-dimension structure for the 26 sources of meaning was achieved. CFAs supported meaningfulness and crisis of meaning as two distinct constructs. Convergent validity within the SoMe-BR and between the SoMe-BR and other scales were also achieved. Regarding the SoMe scores and sociodemographic variables, significant main effects were found for gender, age groups and marital status. Our results corroborate the international literature, which claims in favor of the SoMe as a reliable measure to evaluate meaning in life contents in different cultural contexts.

Tal técnica tem se apresentado como um importante recurso no desenvolvimento, no uso, na avaliação e no refinamento de instrumentos psicométricos. Entretanto, no Brasil há enorme escassez de publicações sobre o tema. Assim, o presente estudo discute a AFCMG, apresentando suas potencialidades. Ao longo do artigo três grandes tópicos são abordados: os diferentes modelos a serem testados, a invariância completa versus a invariância parcial, e os métodos de avaliação de invariância dos modelos. Espera-se que esta leitura auxilie pesquisadores na compreensão, na interpretação e no uso da AFCMG.

A total of 1,160 children, between seven and 16 years of age (M = 11.2; SD = 1.92), from public elementary schools in eight Brazilian southern cities participated in the study. Four studies were conducted for this project. Study I (n = 370) evaluated the factorial structure of the PANAS-C34 (the original 34-item version). Ten potential items were selected for the instrument's refined version. Employing an independent sample (n = 340), Study II assessed the utility of this ten-item version. Exploratory factor analysis, parallel analysis, and confirmatory factor analysis supported a bi-factorial solution. However, significant modification indices emerged for two items (happy and sad) regarding their respective factors and thus they were excluded. In Study III, using another independent sample (n = 450), it was demonstrated that the eight-item version (PANAS-C8) had better fit indices than the ten-item version. In Study IV (N = 1,160) a multigroup confirmatory factor analysis was conducted to evaluate the measurement invariance of the factorial solution across gender. Moreover, convergent validity was also evaluated using the Child Depression Inventory (CDI) and the General Life Satisfaction Scale for Children (GLSS-C). Measurement invariance was obtained for the PANAS-C8 across all the investigated model parameters. The correlations between the PANAS-C8 and both the CDI and the GLSS-C were of similar magnitude to those obtained using the PANAS-C34. The PANAS-C8 had adequate validity indices, demonstrating its usefulness in evaluating positive and negative affect in children.

Participaram do estudo 517 professores, de 57 escolas públicas e privadas da cidade de Campina Grande, Paraíba, Brasil, sendo 174 homens e 343 mulheres (idade média de 36,5 anos, DP = 10,34). Os resultados demonstraram que uma parcela signifi cativa de profi ssionais apresentou índices negativos de SV, BEP e QV. Análises inferenciais apresentaram o SV como uma variável preditora tanto de BEP quanto de QV. Análises de moderação demonstraram que o BEP e a QV geral apresentam correlações distintas para sujeitos com alto e com baixo nível de SV. Refl exões para pesquisas futuras e intervenções em saúde do trabalhador são apontadas.

The PANAS-C8 had adequate validity indices, demonstrating its usefulness in evaluating positive and negative affect in children.

Participaram do estudo 517 professores, de 57 escolas públicas e privadas da cidade de Campina Grande, Paraíba, Brasil, sendo 174 homens e 343 mulheres (idade média de 36,5 anos, DP = 10,34). Os resultados demonstraram que uma parcela signifi cativa de profi ssionais apresentou índices negativos de SV, BEP e QV. Análises inferenciais apresentaram o SV como uma variável preditora tanto de BEP quanto de QV. Análises de moderação demonstraram que o BEP e a QV geral apresentam correlações distintas para sujeitos com alto e com baixo nível de SV. Refl exões para pesquisas futuras e intervenções em saúde do trabalhador são apontadas.

fit indexes when evaluated separately. Multiple group CFA achieved full measurement and structural invariance for gender and age (youngsters, adults and the elderly) groups. Group
comparisons were conducted for evaluating gender, age and marital status differences in both MLQ-P and MLQ-S scales. The results are presented and discussed based on the literature. Our results suggest that the MLQ is a reliable measurement to evaluate presence and search for meaning in life in the Brazilian population in a wide variety of age groups.
not always clearly available. Therefore, the aim of this simulation study was to compare the performance of seven popular statistical models in providing adequate latent trait estimates in conditions of items difficulties targeted at the sample mean or at the tails of the latent trait distribution. Results suggested an overall tendency of models to provide more accurate estimates of true latent scores when using items targeted at the sample mean of the latent trait distribution. Rating Scale Model, Graded Response Model, and Weighted Least Squares Mean- and Variance-adjusted Confi rmatory Factor Analysis yielded the most reliable latent trait estimates, even when applied to inadequate items for the sample distribution of the latent variable. These findings have important implications concerning some popular methodological practices in Psychology and related areas.
