Propriedades psicométricas da versão em português Brasileiro da Physical Appearance Perfectionism Scale

O perfeccionismo direcionado à aparência física considera haver preocupação com a imperfeição e esperança para a perfeição em relação à aparência. O objetivo dessa pesquisa foi validar a versão em português Brasileiro da Physical Appearance Perfectionism Scale em uma amostra de praticantes de exercícios resistidos. A amostra não-probabilística foi constituída por 534 homens e mulheres com idades entre 18 a 39 anos. Foi utilizadaanálise fatorial confirmatória, para gerar evidencias psicométricas para a amostra de referencia. O modelo estrutural bifatorial alcançou índices de ajuste satisfatório, tanto na amostra geral, quanto na amostra por sexo. Em relação à validade convergente, quase todos os valores das cargas fatoriais estavam acima do aceitável, mas a variância média extraída foi adequada apenas na escala masculina. Quanto à validade discriminante, todos os valores da AVE estiveram acima do valor da variância compartilhada nos modelo geral, feminino e masculino, demonstrando haver alguma diferença as duas variáveis latentes. A confiabilidade de constructo foi estabelecida tanto na escala geral, quanto na escala feminina e masculina. O presente instrumento obteve evidencias psicométricas adequadas para a versão brasileira da Physical Appearance Perfectionism Scale, o que permite recomendar seu uso no Brasil. Perfectionism towards physical appearance considers to be concern about imperfection and hope for perfection in appearance. The aim of this research was to validate the Brazilian Portuguese version of Physical Appearance Perfectionism Scale in a sample of exercise resistance practitioners. The non-probabilistic sample consisted of 534 men and women aged 18 to 39 years. Confirmatory factorial analysis was used to generate psychometric evidence for the reference sample. The two-factor structural model achieved satisfactory adjustment indices, both in the general sample and in the sample by sex. Regarding convergent validity, almost all values of factorial loads were above acceptable, although the average variance extracted (AVE) was adequate only in the male scale. Regarding the discriminant validity, all the AVE values were above the value of the shared variance in the general model, female and male, showing that there are some differences between the two latent variables. Construct reliability was established on both the general scale and the female and male scale. This instrument achieved adequate psychometric evidence for the Brazilian version of Physical Appearance Perfectionism Scale, which allows recommending its use in Brazil.

In this paper, we investigated the knowledge management (KM) behavior of executives in Malaysia who work in different sectors and involved in Information Technology (IT) related fields. We proposed a conceptual framework based on the Theory of Reasoned Action (TRA), the Theory of Planned Behavior (TPB) and Unified Theory of Acceptance and Use of Technology (UTAUT) to study their intention and involvement in KM initiatives. The knowledge creation theory (SECI process) was employed to operationalize KM intention and KM behavior. We proposed six independent variables that represent the social-cultural nature of KM as the antecedence of KM intention. These variables are trust, management support, decentralization, IT support, performance expectancy (PE), and effort expectancy (EE). Seventy-four executives from both private and government-linked organizations responded to our online questionnaire. SmartPLS3 was used to run the analysis. The reliability was ensured with the factor loadings, Cronbach’s alpha, Composite Reliability (CR) that met the fit requirement of above 0.6, 0.7 and 0.7 respectively. The convergent validity was confirmed through average variance extracted (AVE) that met the fit requirement of above 0.5. The discriminant validity was assessed by using Fornell and Larcker’s criterion. Finally, the structural model confirmed that only PE of KM, and EE of KM are the significant predictors of KM intention and the KM intention significantly predicts KM behavior. The implications of the findings are discussed in detail at the end of the paper.

El objetivo principal de esta investigación fue adaptar y evaluar culturalmente las propiedades psicométricas del Life Orientation Test para el contexto deportivo (LOT-S). La muestra consistió en 953 jóvenes atletas brasileños de ambos sexos, con una edad media de 16 años. Los resultados del análisis factorial confirmatorio produjeron dos dimensiones correlacionadas, que reflejan optimismo y pesimismo, y brindaron apoyo para un modelo de dos factores. Se encontró un ajuste satisfactorio para LOT-S con 6 ítems (χ2=10.96, df=8; RMSEA=.020 (IC 90%=.021-.049); CFI=.995; TLI=990; NFI=.980; GFI=.996; SRMR=.032). También se generaron pruebas satisfactorias de consistencia interna a través del análisis de cargas factoriales y valores t. Los índices alfa de Cronbach (.68/ .65) y la Fiabilidad Compuesta (.72/ .65) fueron adecuados en las variables latentes Optimismo y Pesimismo, respectivamente. Los valores de varianza promedio extraídos fueron insatisfactorios, sin embargo, las correlaciones positivas con Optimismo y las correlaciones negativas con Pesimismo entre Motivación, Resiliencia y Bienestar fueron indicativas de validez convergente. Las correlaciones entre las variables latentes en comparación con las raíces cuadradas de los valores de varianza promedio extraídos de cada constructo mostraron que el modelo tiene validez discriminante. Se logró la invariancia configuracional, métrica y escalar, lo que indica que LOT-S puede medir atletas de ambos sexos por igual. Aunque se necesitan más estudios para confirmar las propiedades psicométricas del instrumento, la adaptación de LOT al contexto deportivo fue el primer paso en el futuro sobre la influencia del Optimismo en el rendimiento deportivo Palabras clave: optimismo; pesimismo; dimensionalidad; estudio de validación The main objective of this research was to culturally adapt and evaluate the psychometric properties of the Life Orientation Test version for the sports context (LOT-S). The sample consisted of 953 young Brazilian athletes of both sexes, with a mean age of 16 years. The results of the confirmatory factor analysis produced two correlated dimensions, reflecting optimism and pessimism, and provided support for a two-factor model. A satisfactory fit for LOT-S with six items was found (χ2=10.96, df=8; RMSEA=.020 (IC 90%=.021-.049); CFI=.995; TLI=990; NFI=.980; GFI=.996; SRMR=.032). Satisfactory tests of internal consistency were also generated through the analysis of factorial loads and t-values. Cronbach's alpha (.68/ .65) and Composite Reliability (.72/ .65) were adequate in Optimism and Pessimism, respectively. The values of average variance extracted were unsatisfactory, however, positive correlations with optimism and negative with pessimism between Motivation, Resilience and Well-Being were indicative of convergent validity. The correlations between the latent variables compared to the square roots of the average variance extracted values of each construct showed that the model has discriminant validity. The configural, metric and scalar invariance was achieved, indicating that the LOT-S can measure athletes of both sexes equally. Although more studies are needed to confirm the psychometric properties of the instrument, adapting the LOT to the sport context was the first step in the future works about the influence of Optimism on sports performance.

ABSTRACT Metamemory measures provide subjective memory information and are relevant to investigate memory ability in aging. However, there is a lack of metamemory instruments available in Brazil. Objective: The aim of this study was to examine the psychometric properties of the Brazilian version of the Multifactorial Memory Questionnaire (MMQ), which evaluates different dimensions of subjective memory functioning, such as Feelings, Abilities and Strategies used in everyday life. Methods: The MMQ was translated into Portuguese and administered to 30 Brazilian elderly subjects. The participants underwent cognitive tests, mood scales and metamemory instruments. Results: Analyses revealed good internal consistency (Cronbach's a coefficient ranged from 0.75 to 0.89) and test-retest validity for each MMQ dimensions (positive correlations between two applications ranged from 0.75 to 0.8). Convergent validity evidence for the MMQ was confirmed by significant positive correlations (0.47 to 0.68) with dimensions of the Metamemory in Adulthood scale (MIA) (i.e., the Ability, Control, Self-efficacy and Strategy dimensions). Discriminant validity revealed no associations between the MMQ and cognitive performance, suggesting a weak metamemory-objective memory correspondence. Moreover, there was a negative correlation between MMQ-Ability subscale scores and mood symptoms (-0.63 for anxious symptoms, and -0.54 for depressive symptoms); and the Brazilian MMQ was comparable with MMQ translations to other languages. Conclusion: The Brazilian MMQ exhibits good psychometric properties and appears promising for clinical and research purposes. Additional studies are needed to further examine the psychometric properties of the Brazilian MMQ in a larger sample.

Abstract There is growing interest on the relationship between attachment and work- or career-related decisions. However, to this date, there are no scientific reports assessing adult attachment in work environment in Brazilian samples. This study aimed to adapt and collect psychometric evidence from the Short Work Attachment Measure for Brazilian Portuguese. A total of 450 adults (62.2% women; mean age = 23.8 years old) from a Southeastern state of Brazil participated in this research. Exploratory and confirmatory factorial procedures replicated the original version of the two-dimensional structure of the measure. The McDonald’s Omega accuracy indicators were higher than 0.78 for the instrument. Evidence of convergent validity was observed with a measure of attachment to romantic relationships and life satisfaction. We concluded that the Brazilian version of SWAM presents adequate psychometric properties

Average Variance

The Psychological Capital Questionnaire (PCQ) is the most commonly used measure for assessing psychological capital in work settings. Although several studies confirmed its factorial validity, most validation studies only examined the four-factor structure preconized by Luthans, Youssef, and Avolio, not attending to empirical evidence on alternative factorial structures. The present study aimed to test the psychometric properties of the Portuguese version of the PCQ, by using two independent samples (NS1 = 542; NS2 = 115) of Portuguese employees. We conducted a series of confirmatory factor analyses and found that, unlike previous findings, a five-factor solution of the PCQ best fitted the data. The evidence obtained also supported the existence of a second-order factor, psychological capital. The coefficients of internal consistency, as measured by Cronbach’s alpha, were adequate and test–retest reliability suggested that the PCQ presented a lower stability than personality factors. Convergent validity, assessed with average variance extracted, revealed problems in the optimism subscale. The discriminant validity of the PCQ was confirmed by its correlations with Positive and Negative Affect and Big Five personality factors. Hierarchical regression analyses showed that this measure has incremental validity over personality and affect when predicting job performance.

Abstract This study aimed to validate the Brazilian version of the RMS Tactile Scale (B-RMS-TS) in children and adolescents with visual impairment. Ten visually impaired children and adolescents between 10 and 17 years old of an Educational Center for Visually Impaired People answered the verbalized Dental Anxiety Scale (DAS), and the DAS in Braille to evaluate their dental anxiety levels. B-RMS-TS construct validity was assessed by convergent and discriminant validity. Convergent validity was tested in two ways: Pearson's correlation between the B-RMS-TS and the overall anxiety question; Pearson's correlation between B-RMS-TS and verbalized DAS and DAS in Braille. B-RMS-TS reliability was measured by internal consistency (Cronbach's alfa and McDonald's omega) and test-retest reliability (ICC). B-RMS-TS was moderately correlated to the overall anxiety question (r=0.493;p=0.147). B-RMS-TS showed excellent correlation with verbalized DAS (r=0.971;p<0.001) and DAS in Braille (r=0.934;p<0.011). B-RMS-TS was able to discriminate dental anxiety levels between male and female (p=0.008). The B-RMS-TS demonstrated excellent reliability (Cronbach's alpha=0.661, McDonald's omega=0.700 and ICC=0.987; 95%CI=0.817-0.999). B-RMS-TS is valid and reliable to measure dental anxiety levels in Brazilian children and adolescents with visual impairment.

Women are likely to leave the job sector as a result of the crisis between their commitments to the career with the household interest. In response to this issue, this study aims to build a career challenge model that caters to the demand among women in this century. Hence, this study has identified the key factors to the challenges faced by female engineers in pursuing their career as an engineer through the Delphi Modified Technique. The result shows this study looking into the relationship between four independent constructs namely, life balance, childcare, leaves and gender discrimination. Meanwhile, the dependent construct of this study is career challenges faced by women. The scope of the study comprises female engineers with families and 211 respondents were selected to answer the questionnaire. The data obtained were analysed using the PLS-SEM 2.0 software via the algorithm, bootstrapping and blindfolding method. The construction process of this model involves two tests including the construction of the measurement model and the structure model. Testing the measurement model involves internal consistency namely (a) convergent validity and (b) discriminant validity in which these two validities have six analyses; (i) external loading, (ii) composite reliability, (iii) average variance extracted (AVE), (iv) Fornell-Larcker, (v) cross loading, and (vi) Heterotrait-Monotrait Ratio (HTMT). Meanwhile, the structural model testing involves the analysis of (i) Multicollinearity (Inner VIF), (ii) Path Coefficient, (iii) R square (R2), (iv) size effect (f2), and (v) Predictive Relevance (Q2). The findings indicate that gender discrimination and life balance have significant relationships in influencing career challenges. Hence, this model is expected to contribute to the literature of Human Resource Management.

Background and Purpose: This study aimed to evaluate the reliability and the construct validity of the Brazilian version of the Self-Efficacy for Appropriate Medication Adherence Scale (SEAMS). Methods: One hundred forty-seven patients with coronary artery disease participated in the study. Reliability was estimated by composite reliability (CR). Convergent validity was estimated by the factor loading and average variance extracted (AVE). The discriminant validity was assessed by cross-factor loadings, comparing the square roots of AVEs by correlation coefficients between latent constructs and disattenuated correlation. Results: The values of CR of .88 and .99 for Factors 1 and 2, respectively, indicate internal consistency reliability. Values of AVE = 0.52 for Factor 1 and 0.69 for Factor 2 to the convergent validity of the model. Cross-factor loadings were found ≥.50 for all items of the scale in areas that were allocated in the original instrument, square roots of AVEs higher than the correlations between the constructs and desatenuada correlation (r = .83), suggesting discriminant validity fashion model. Conclusion: Confirmatory factor analysis partially yielded the construct validity of the Brazilian version of the SEAMS.

The purpose of the present study was to provide a deeper understanding of multidimensional aspects of attitudes and social norms in educational contexts. Specifically, the current investigation aimed to (1) examine reliability and validity of factorial structure of math attitudes (Affective, Behavioral, and Cognitive factors) and perceived math social norms (Parent, Peer, and Teacher factors) and (2) test whether measurement of all factors would be invariant across national groups. Three nationally representative sample data (USA, Hong Kong, and Singapore; N = 15,019) were obtained from the 2012 Programme of International Student Assessment (PISA) database. High values in Cronbach’s Alpha, Composite Reliability scores, and factor loadings indicated strong internal consistency and convergent validity of all factors. Estimated correlations among latent factors were ranged from small to moderate in value (rs = .21 - .51, ps < .001) and each square root of average variance extracted turned out to be greater than all bivariate correlations (.71 - .85), which supported clear discriminant validity. Furthermore, the results of Multigroup Confirmatory Factor Analysis (MGCFA) yielded that measurement of the six factors was equivalent across national groups at the level of strong (scalar) factorial invariance. Implications for math education and future research are discussed.

Novel Concept

The present article includes two studies that have tested the reliability and validity of the Romanian adaptation of the Employee Intrapreneurship Scale (EIS). Intrapreneurship is a relatively novel concept describing proactive behaviors through which employees contribute to the growth and development of organizations they are employed in. The factorial structure and gender invariance of the EIS have been tested in the first sample, including 307 employees with diverse occupational backgrounds. The factorial structure was cross-validated in a second sample, including 122 employees with a similar composition. The second study also established convergent validity of the scale through testing its’ associations to risk-taking, innovativeness, and proactive personality. Discriminant validity was tested using the Average Variance Extracted (AVE) procedure. The results have confirmed a factor structure whereby employee intrapreneurship is composed of two latent indicators: strategic renewal and corporate venturing. Reliability indices and factor loadings have shown a consistent and valid measure of intrapreneurship at the employee level. Furthermore, the concept showed significant positive associations to other constructs in the nomological network, and the AVE indicated satisfactory discriminant validity. Overall, these studies provide a psychometrically valid measure to be used in intrapreneurship research in Romanian organizations.
