ABSTRACT
Abstract The aim of this study is to analyze the psychometric properties and to examine the factorial validity of the Portuguese version of the Questionnaire Assessing School Physical Activity Environment (Q-SPACE) for school-age youth. The translated and adapted version of the questionnaire was applied and resulted in two studies: study I, in which 504 students participated (56% boys), the factorial structure of the scale was examined; in study II, which involved 501 students (53.5% boys), the factorial structure obtained in study I was tested through confirmatory factor analysis. The results of the exploratory factorial analysis, carried out in study I, showed that the Portuguese version of the Q-SPACE is composed of five factors that characterize the students' perception regarding the social and physical school environment for physical activity: equipment and space conditions; recess; school social support; physical education structure; school activity offer. Internal consistency values ranged from 0.60 to 0.89. The confirmatory factor analysis confirmed the applicability of the Portuguese Q-SPACE version, presenting adequate fit indexes: χ2/df = 2.90, GFI = 0.92; CFI = 0.92; RMSEA = 0.06. In conclusion, Q-SPACE showed acceptable validity and reliability for assessing school physical activity environment in Portuguese adolescents.
Resumo O objetivo deste estudo é analisar as propriedades psicométricas e examinar a validade fatorial da versão portuguesa do instrumento "Questionnaire Assessing School Physical Activity Environment" (Q-SPACE) para jovens em idade escolar. A versão traduzida e adaptada da escala foi aplicada e resultaram dois estudos: no estudo I, em que participaram 504 estudantes (56% eram rapazes), foi examinada a estrutura fatorial da escala; no estudo II, em que participaram 501 estudantes (53.5% eram rapazes), foi testada a estrutura fatorial obtida no estudo I através da análise fatorial confirmatória. O resultado da análise fatorial exploratória, efetuada no estudo I, demonstrou que a versão portuguesa da escala Q-SPACE é constituída por cinco fatores que caraterizam a perceção dos estudantes relativamente ao ambiente social e físico escolar para a prática de atividade física: condições dos espaços e material; intervalos; suporte social escolar; organização da educação física; diversidade de atividades. Os valores de consistência interna variaram entre 0.60 e 0.89. A análise fatorial confirmatória, comprovou a aplicabilidade da versão portuguesa do Q-SPACE, apresentando adequados índices de ajustamento: χ2/df = 2.90, GFI = 0.92; CFI = 0.92; RMSEA = 0.06. Em conclusão, a escala Q-SPACE demonstrou uma validade e fiabilidade adequadas para avaliar a perceção do ambiente escolar para a prática de atividade física em adolescentes portugueses.

Resumen El objetivo de este estudio fue validar el Inventario de Adicción al Ejercicio (EAI) en el contexto brasileño. Participaron en el estudio 251 estudiantes universitarios (hombres = 132, mujeres = 119, Medad = 22.34, DT = 4.65). Los resultados mostraron un adecuado ajuste del modelo a los datos: χ2 (9, N = 251) = 17.45, p = 0.04; χ2/gl = 1.94; CFI = 0.96; IFI = 0.96; RMSEA = 0.061 (IC 90 % = 0.01-0.10); SRMR = 0.041. La estructura factorial se mostró invariante respecto del género. Se obtuvieron adecuados valores de consistencia interna (ρ = 0.70) y estabilidad temporal (CCI = 0.80). Dieciséis (6.4 %) participantes fueron clasificados en riesgo de adicción, 198 (78.9 %) como sintomáticos y 37 (14.7 %) como asintomáticos. Se obtuvieron evidencias que permiten sugerir la validez y la fiabilidad del EAI en el contexto brasileño. No obstante, las investigaciones con poblaciones más diversas deberían determinar la aplicabilidad general del EAI.
Abstract The purpose of this study was to validate the Exercise Addiction Inventory (EAI) in the Brazilian context. A total of 251 university students (male = 132, female = 119, Mage = 22.34, SD = 4.65) participated in the study. Results showed an adequate fit to the data: χ2 (9, N = 251) = 17.45, p = .04; χ2/gl = 1.94; CFI = .96; IFI = .96; RMSEA = .061 (IC 90 % = .01-.10); SRMR = .041. The factorial structure was invariant across gender. Adequate values of internal consistency (ρ = .70) and temporal stability (ICC = .82) were obtained. Sixteen students (6.4 %) were classified at risk of exercise addiction, 198 (78.9 %) as symptomatic and 37 (14.7 %) as asymptomatic. Evidence for the reliability and validity of the EAI in the Brazilian context were obtained. Nevertheless, research in more diverse populations is needed to further examine the general applicability of the EAI.

Introducción: La inteligencia emocional ha demostrado tener relaciones con el desempeño académico y el laboral, sin embargo, las propiedades psicométricas de escalas utilizadas para su medición han sido escasamente analizadas en culturas latinoamericanas, como es el caso del Cuestionario Rasgo Inteligencia Emocional Versión Corta (TEIQue- SF por sus siglas en inglés). Objetivo: Analizar la confiabilidad de sus factores y facetas, examinar su estructura factorial y determinar su validez concurrente. Metodología: Estudio observacional analítico realizado con base en una muestra guiada por participantes compuesta de estudiantes de una universidad mexicana (N=155). La confiabilidad se determinó con alfa de Cronbach y coeficiente omega, la estructura factorial y su validez mediante análisis factoriales exploratorios y confirmatorios, y la validez concurrente teniendo como criterio las escalas afecto positivo y afecto negativo del PANAS. Resultados: Se obtuvieron en general índices de confiabilidad reducidos para los factores de la escala original (alfa de Cronbach entre .32 a .82; coeficiente omega entre .16 a .83), y su estructura original no pudo comprobarse en el análisis factorial confirmatorio (X2=768.47, gl=390 y p=.0000, CFI=.65, RMSEA=.008, 90% IC=.071-.087). Los análisis factoriales exploratorios tampoco sustentaron la validez de constructo, al obtenerse una estructura en que se mezclaron entre sí los ítems de distintos factores y facetas. La validez concurrente tanto de la escala original como de la obtenida con los nuevos factores pareció insuficiente al obtener algunas correlaciones significativas débiles tanto con el afecto negativo como con el afecto positivo (r entre -.04 y .21). Conclusiones: La escala no mostró adecuadas propiedades psicométricas en la muestra participante, y son necesarios más estudios que sustenten estos hallazgos, recalcando que es importante publicar resultados negativos en estos casos.
Introduction: Emotional intelligence has been shown to have relationships with academic performance and work, however, the psychometric properties of scales used for measurement have been poorly analyzed in Latin American cultures, such as Trait Emotional Intelligence Questionnaire Short Form (TEIQue-SF for its acronym in English). Objectives: To analyze the reliability of its factors and facets, examine its factorial structure and determine concurrent validity. Methodology: Analytical observational study based on a sample guided by participants composed of students from a Mexican university (N = 155). Reliability was determined with Cronbach's alpha and omega coefficient, the factor structure and validity through exploratory and confirmatory factor analyzes, and concurrent validity having criterion positive affect and negative affect scales PANAS. Results: Were obtained generally reduced reliability indices for the factors of the original scale (Cronbach's alpha between .32 to 8.2; omega coefficient between .16 to .83), and its original structure could not be verified in the confirmatory factor analysis (X2=768.47, df=390 and p=.0000, CFI=.65, RMSEA=.008, 90% CI=.071-.087). Exploratory factor analyzes also did not sustain construct validity, by obtaining a structure in which mixed together items of different factors and facets. The concurrent validity of both the original scale and obtained with the new factors seemed weak to get some significant correlations with both negative affect as positive affect (r between -.04 and .21). Conclusions: The scale did not show adequate psychometric properties in the participant sample, and more studies are needed to substantiate these findings, stressing that it is important to publish negative results in these cases.

FUNDAMENTO: A prevalência de depressão em portadores de doença arterial coronariana (DAC) é alta. A escala de depressão geriátrica (EDG) é um instrumento amplamente usado para rastrear a depressão em idosos. No Brasil, as propriedades psicométricas da versão curta ainda não foram adequadamente exploradas. OBJETIVO: Avaliar as propriedades psicométricas da versão curta da EDG em portadores de DAC em ambulatório de cardiologia. MÉTODOS: Estudo transversal que avaliou 209 idosos (≥ 65 anos) com DAC utilizando a EDG-15, Cumulative Illness Rating Scale for Geriatrics (CIRS), Brazilian OARS Multidimensional Function Assessment Questionnaire (BOMFAQ) e The Cambridge Examination for Mental Disorders of the Elderly (CAMDEX). A consistência interna da EDG-15 foi calculada pelo KR-20. Uma análise fatorial dessa escala foi conduzida. Escores da EDG-15 foram comparados com os diagnósticos de depressão (DSM-IV) para a validade de critérios. Na análise de validade concorrente, os mesmos escores foram correlacionados com os das escalas de depressão CAMDEX, Miniexame do Estado Mental (MEEM), Cambridge Cognitive Examination (CAMCOG) e BOMFAQ. RESULTADOS: A depressão clínica foi diagnosticada em 35,71 por cento da amostra avaliada de acordo com o DSM-IV. Para o diagnóstico de depressão maior ou distimia, o ponto de corte 5/6 apresentou acurácia moderada (AUROC = 0,84), sensibilidade de 79,92 por cento e especificidade de 78,29 por cento. A consistência interna foi de 0,80. Na análise fatorial, três fatores obtidos explicaram 52,72 por cento da variância total observada. Os escores da EDG-15 correlacionaram-se com os da escala de depressão CAMDEX. CONCLUSÃO: No geral, a EDG-15 apresentou boa confiabilidade e validade (concorrente e de critério). Em settings cardiológicos, seu uso pode auxiliar no rastreamento de quadros depressivos de forma simples e rápida.
BACKGROUND: The prevalence of depression in individuals with coronary artery disease (CAD) is high. The Geriatric Depression Scale (GDS) is a broadly used tool to screen for depression in elderly individuals. In Brazil, the psychometric properties of the short version have not been adequately assessed. OBJECTIVE: To evaluate the psychometric properties of the short version of the GDS in patients with CAD treated at a Cardiology Outpatient Clinic. METHODS: The present is a cross-sectional study that assessed 209 elderly individuals (≥ 65 years) with CAD using the GDS-15, the Cumulative Illness Rating Scale for Geriatrics (CIRS-G), the Brazilian OARS Multidimensional Function Assessment Questionnaire (BOMFAQ) and The Cambridge Examination for Mental Disorders of the Elderly (CAMDEX). The internal consistency of the GDS-15 was calculated through the KR-20. A factorial analysis of this scale was carried out. The GDS-15 scores were compared with the diagnoses of depression (DSM-IV) for the validity of criteria. At the analysis of concurrent validity, the same scores were correlated with those of the CAMDEX, mini-mental state examination (MMSE), Cambridge Cognitive Examination (CAMCOG) and BOMFAQ depression scales. RESULTS: Clinical depression was diagnosed in 35.71 percent of the sample assessed according to the DSM-IV. For the diagnosis of major depression or dystimia, the cutoff 5/6 presented moderate accuracy (AUROC = 0.84), sensitivity of 79.92 percent and specificity of 78.29 percent. The internal consistency was 0.80. At the factorial analysis, three obtained factors explained 52.72 percent of the total variance that was observed. The GDS-15 scores correlated with those of the CAMDEX depression scale. CONCLUSION: In general, the GDS-15 presented good reliability and validity (concurrent and of criterion). In cardiologic settings, its use, which is simple and fast, can be utilized in the screening for depression.
