Attitudes toward HIV/aids in students at secondary schools in Mozambique: A comparative study between Maputo and Niassa provinces
O objetivo do estudo foi analisar as atitudes dos alunos das províncias de Maputo e Niassa frente ao vírus HIV-aids, nas escolas secundárias onde o programa Geração Biz está sendo implementado e em escolas onde não está sendo implementado. Participaram 391 alunos, sendo utilizado o Questionário Sociodemográfico e a Escala de Atitudes Frente ao HIV-aids (EAFAIDS). Os alunos de Maputo apresentaram valores mais positivos em todas as dimensões na EAFAIDS. Os alunos cujas escolas estão implementando o programa obtiveram atitudes mais positivas apenas na dimensão da relação com os soropositivos na EAFAIDS. Conclui-se que as ações de prevenção devem ter em conta as diferenças socioculturais do país. Palavras-chave: HIV-aids; educação para a saúde; atitudes sociais. The aim of this study was to analyze student’s attitudes from the provinces of Maputo and Niassa regarding HIV-aids in the secondary schools where the Generation Biz program is being implemented and in schools where it is not implemented. 391 students participated, using the Socio-demographic Questionnaire and the Scale of Attitudes towards HIV-aids (EAFAIDS). Students in Maputo showed more positive results in all scopes of EAFAIDS. Students whose schools are implementing the program had more positive attitudes only in relation to the size of the HIV positive people in EAFAIDS. It is concluded that prevention efforts must take into account the country's socio-cultural differences. Keywords: HIV-aids; health education; social attitudes
Psychometric properties of the World Health Organization Quality of Life Instrument-Abbreviated version in Portuguese-speaking adults from three different countries
To evaluate the validity, reliability and invariance of the World Health Organization Quality of Life Instrument-Abbreviated version (WHOQOL-Bref) in Portuguese-speaking adults from three different countries.Objetivo: Avaliar a validade, a confiabilidade e a invariância do
World Health Organization Quality of Life instrument-Abbreviated
version (WHOQOL-Bref) em adultos de três diferentes países de
língua portuguesa.
Métodos: Um total de 4.020 indivíduos brasileiros, portugueses e
moçambicanos participaram do estudo. A amostra total foi dividida
em quatro amostras: pacientes brasileiros (n = 1.120), estudantes
brasileiros (n = 1.398), estudantes portugueses (n = 1.165) e
estudantes moçambicanos (n = 337). A validade fatorial do
WHOQOL-Bref foi avaliada por meio de análise fatorial confirmatória.
As validades convergente e discriminante do instrumento foram
avaliadas utilizando a variância média extraída (VEM) e o quadrado
do coeficiente de correlação de Pearson (r2), respectivamente. A
confiabilidade composta e o coeficiente alfa ordinal foram utilizados
como medidas de confiabilidade. As invariâncias métrica, escalar e
estrita do WHOQOL-Bref foram avaliadas por análise multi-grupos
em subamostras independentes (dentro de cada amostra) e
somente entre Brasil e Portugal (transnacional), porque o modelo
configuracional de Moçambique era diferente.
Resultados: O modelo original do WHOQOL-Bref não apresentou
bom ajustamento para as amostras. Diferentes itens foram
excluídos para ajustar o instrumento em cada amostra (modelos
diferentes para o WHOQOL-Bref entre amostras brasileiras,
portuguesas e moçambicanas). A VEM e o r2 não foram adequados;
entretanto, a confiabilidade do WHOQOL-Bref foi boa, exceto na
amostra moçambicana. A invariância foi encontrada apenas em
subamostras independentes.
Conclusão: Os modelos ajustados do WHOQOL-Bref apresentaram
adequada validade fatorial e invariância em subamostras
independentes. A não invariância transnacional do WHOQOL-Bref
revela a influência da cultura na operacionalização do construto
qualidade de vida.FAPESP; Conselho Nacional de Desenvolvimento Científico

Body weight concerns: Cross-national study and identification of factors related to eating disorders
Body weight concerns are common among individuals with eating disorders, and this construct can be assessed using psychometric instruments. The Weight Concerns Scale (WCS) is commonly used to assess body weight concerns.FAPESP; CAPES; CNPQinfo:eu-repo/semantics/publishedVersio
Psychometric properties of the World Health Organization Quality of Life Instrument-Abbreviated version in Portuguese-speaking adults from three different countries
Abstract Objective: To evaluate the validity, reliability and invariance of the World Health Organization Quality of Life Instrument-Abbreviated version (WHOQOL-Bref) in Portuguese-speaking adults from three different countries. Methods: A total of 4,020 Brazilian, Portuguese, and Mozambican individuals participated in the study. The total sample was divided into four samples: Brazilian patients (n = 1,120), Brazilian students (n = 1,398), Portuguese students (n = 1,165) and Mozambican students (n = 337). Factorial validity of the WHOQOL-Bref was assessed by confirmatory factor analysis. The convergent and discriminant validities of the instrument were assessed using the average variance extracted (AVE) and the square of Pearson's correlational coefficient (r2), respectively. Composite reliability and ordinal alpha were used as measures of reliability. The metric, scalar, and strict invariance of WHOQOL-Bref was evaluated by multi-group analysis in independent subsamples (within each sample) and only between Brazil and Portugal (transnational invariance), because the configural model of Mozambique was different. Results: The original model of the WHOQOL-Bref did not show a good fit for the samples. Different items were excluded to fit the instrument in each sample (different models for WHOQOL-Bref among Brazilian, Portuguese, and Mozambican samples). AVE and r2 were not adequate; however, the reliability of the WHOQOL-Bref was good, except in the Mozambican sample. Invariance was observed only in independent subsamples. Conclusion: The WHOQOL-Bref fitted models showed adequate factorial validity and invariance in independent subsamples. The transnational non-invariance of the WHOQOL-Bref shows the influence of culture on the operationalization of the quality of life construct

Body Image Quality of Life Inventory: cross-national study in college students from four different countries
Purpose This study was aimed to examine the psychometric proprieties of the Body Image Quality of Life Inventory (BIQLI) among Brazilian, Portuguese, Mozambican, and Italian college students. Methods A total of 1630 subjects (Brazilians = 446; Portuguese = 480, Mozambicans = 360, and Italians = 344) completed the Portuguese (Brazilian, Portuguese, and Mozambican students) and the Italian versions (Italian students) of the BIQLI for measuring the effects of body image on one's quality of life. Psychometric testing included confirmatory factor analysis (CFA), discriminant and convergent validity, internal consistency, and composite reliability. The cross-national invariance of the BIQLI was assessed by multi-group analysis using Delta CFI. Moreover, the global score of the BIQLI for all countries was calculated by an algorithm and compared using the Welch's ANOVA and the Games-Howell post-test (alpha = 5%). Results CFA showed an inadequate fit of unifactorial model of the BIQLI. Therefore, an alternative model comprising nine first-order factors and one second-order factor was proposed and evaluated. This new model showed adequate fit in all samples, despite some limitations that were found with respect to its convergent and discriminant validity. The alternative BIQLI model was invariant among countries. Global scores for the influence of body image on quality of life were significantly different across countries, with the Italians presenting the lowest scores. Conclusions The BIQLI factorial model found in this study represents a reliable and valid alternative to its original structure for the assessment of the effect of body image on college students' perceived quality of life. This model must be further tested in other populations
