The main models used so far, are based on dimensions of normal personality traits, bringing conflicting results. Hence, there is a demand for instruments that can give more accuracy and improve the study of the personality in this population capturing more dysfunctional traits. In a special section for emerging measures, the new edition of the Diagnostic Statistical Manual of Psychiatric Disorders (DSM-5) proposed an instrument to measure personality mal-adaptive traits: the Personality Inventory for DSM-5 (PID-5), whose psychometric properties have been tested in several samples and localities. Despite promising results, PID-5 has not yet been evaluated psychometrically in other clinical populations where the "personality" construct can have an important impact (in etiologic and prognostic ways), such as obese candidates for bariatric surgery. Objective: The aim of this study is to investigate the psychometric properties of the PID-5 in the evaluation of pathological personality traits in obese candidates for bariatric surgery. This constitutes a fundamental step to assess whether the instrument keeps its original technical features allowing its use and correct interpretation in this population. Setting: Centro da Obesidade e S?ndrome Metab?lica, Pontif?cia Universidade Cat?lica do Rio Grande do Sul (COM-PUCRS), Porto Alegre, Brazil Methods: Cross-sectional study involving 312 medical records of patients who applied for bariatric surgery. We collected demographic data and scores from instruments applied in the psychiatric evaluation routine. The reliability of facets and domains was evaluated through internal consistency indices and the unidimensionality of facets was verified through factorial methods. Exploratory Structural Equations Modeling was performed to test the higher order structure of the model. To investigate convergent validity, linear correlations were calculated between PID-5 scales and instrument scores of correlated constructs (depression, anxiety, defensive styles, and quality of life). Given the characteristic of the sample, we also correlated PID-5 with body mass index (BMI) and binge eating symptoms. Data was analyzed by Factor and Mplus softwares. Results: Facets were unidimensional, with the exception of Risk Taking, better explained by two factors. We replicate the higher order structure of 5 factors of the original model, with good congruence coefficients. The internal consistency of the domains was satisfactory, however, some facets showed fragility of internal consistency, mainly when calculated with more robust methods. In general, the domains and facets correlated as expected with correlated constructs. Conclusion: This study found evidences of adequate psychometric properties of PID-5 for a sample of obese candidates for bariatric surgery. Our results indicate that the instrument is appropriate to be applied in this population, consistently evaluating personality domains and facets of the DSM-5 model. More studies in other centers are needed to replicate and reinforce our findings. / Introdu??o: Tra?os de personalidade s?o um construto importante no estudo da obesidade, tanto para entender sua influ?ncia na g?nese desta condi??o, quanto para avaliar o papel que desempenham nas respostas aos tratamentos, como a cirurgia bari?trica. At? o momento, os principais instrumentos utilizados para o estudo desta rela??o baseiam-se em modelos que avaliam dimens?es de tra?os normais da personalidade, trazendo resultados conflitantes. Existe portanto, uma demanda por instrumentos que possam fornecer maior acur?cia e aperfei?oar o estudo da personalidade nesta popula??o, captando tra?os mais disfuncionais. Em uma se??o especial para medidas emergentes, a nova edi??o do Manual Estat?stico Diagn?stico dos Transtornos Psiqui?tricos (DSM-5) prop?s um instrumento para mensurar tra?os mal-adaptativos de personalidade: o Personality Inventory for DSM-5 (PID-5), cujas propriedades psicom?tricas vem sendo testadas em diversas amostras e localidades. A despeito de promissores resultados, o PID-5 ainda n?o foi avaliado psicometricamente em outras popula??es cl?nicas onde o construto ?personalidade? pode ter um impacto importante (em termos etiol?gicos e progn?sticos), como a constitu?da por obesos candidatos a cirurgia bari?trica. Objetivo: Investigar as propriedades psicom?tricas do PID-5 na avalia??o dos tra?os patol?gicos de personalidade em pacientes obesos candidatos a cirurgia bari?trica. Esta ? uma etapa metodol?gica fundamental para verificar se o instrumento mant?m suas caracter?sticas t?cnicas originais viabilizando seu uso e correta interpreta??o nesta popula??o. Local: Centro da Obesidade e S?ndrome Metab?lica, Pontif?cia Universidade Cat?lica do Rio Grande do Sul (COM-PUCRS), Porto Alegre, Brasil M?todos: Estudo transversal envolvendo 312 prontu?rios de pacientes candidatos a cirurgia bari?trica. Foram coletados dados demogr?ficos e escores de instrumentos aplicados na rotina de avalia??o psiqui?trica pr?-operat?ria. A fidedignidade das facetas e dom?nios do PID-5 foi avaliada atrav?s de ?ndices de consist?ncia interna e a unidimensionalidade das facetas atrav?s de m?todos fatoriais. O teste da estrutura de ordem superior foi realizado por meio do Modelagem de Equa??es Estruturais Explorat?rias. Para investigar a validade convergente, foram calculadas correla??es lineares entre as escalas do PID-5 e os escores de instrumentos de construtos correlatos (depress?o, ansiedade, estilos defensivos e qualidade de vida). Dada a caracter?stica da amostra, tamb?m correlacionamos o instrumento com o ?ndice de massa corporal (IMC) e sintomas compulsivos alimentares. Os dados foram analisados pelos softwares Factor e Mplus. Resultados: As facetas de personalidade apresentaram-se de forma unidimensional, ? ?nica exce??o de Exposi??o a Riscos, melhor explicada por dois fatores. Replicamos a estrutura de ordem superior de 5 fatores do modelo original, com bons coeficientes de congru?ncia. A consist?ncia interna dos dom?nios foi satisfat?ria, entretanto algumas facetas demonstraram fragilidades de consist?ncia interna, sobretudo calculados com m?todos mais robustos. De forma geral, os dom?nios e facetas correlacionaram-se de forma esperada com os construtos correlatos. Conclus?o: Este estudo encontrou evid?ncias de propriedades psicom?tricas adequadas do PID-5 para uma amostra de obesos graves candidatos a cirurgia bari?trica. Nossos resultados indicam que o instrumento ? apropriado para ser aplicado nesta popula??o, avaliando coerentemente os dom?nios e facetas da personalidade do modelo DSM-5. Mais estudos em outros centros s?o necess?rios para replicar e refor?ar nossos achado.

Desta forma o objetivo geral desta pesquisa foi adaptar e analisar as evid?ncias psicom?tricas da Cambridge Worry Scale, que avalia preocupa??es maternas em gestantes. Os objetivos espec?ficos foram: a) fazer a adapta??o sem?ntica dos itens da Cambridge Worry Scale do ingl?s para o portugu?s brasileiro b) avaliar evid?ncias de validade de conte?do atrav?s do Coeficiente de Validade de Conte?do (Etapa 1); c) verificar elementos de validade e confiabilidade da Cambridge Worry Scale atrav?s de procedimentos de avalia??o psicom?tricos (Etapa 2). Adapta??o transcultural de corte transversal realizada com 420 gestantes a partir de 13 anos de idade assistidas em Unidades B?sicas de Sa?de de Natal (RN). Utilizou-se como instrumentos: 1) Question?rio Estruturado (dados sociodemogr?ficos e gestacionais); 2) Cambridge Worry Scale (CWS); 3) Perfil Psicossocial no Pr?-natal (PPP); e a Escala de Apoio Social. O projeto cumpriu os aspectos ?ticos tendo obtido parecer favor?vel (572.558/ 2014) do Comit? de ?tica em Pesquisa da UFRN. As an?lises dos dados foram feitas com o aux?lio do software SPSS (21.0). Na Etapa 1 efetuou-se estat?sticas descritivas (frequ?ncia e Coeficiente de Valida??o de Conte?do - CVC) e c?lculo do Kappa de Fleiss. Na Etapa 2 usou-se an?lise fatorial explorat?ria e confirmat?ria, teste t, ANOVA, correla??es de Pearson; e c?lculo do alfa de Cronbach. Na Etapa 1 obteve-se a autoriza??o formal dos autores; prepara??o e consolida??o da vers?o preliminar; e valida??o de conte?do acerca dos crit?rios Clareza, Pertin?ncia Pr?tica e Relev?ncia Te?rica, cujos CVC foram maiores que 0,8 na maior parte dos itens. A Dimens?o Te?rica apresentou concord?ncia substancial (k=0,7164). A Etapa 2 refere-se ? coleta de dados de 420 gestantes. A m?dia de idade foi 26,85 (?8,93) anos, a maioria apresentou baixa escolaridade e renda, era dona de casa, cat?lica, e vivia em uni?o est?vel. Predominaram mult?paras, com baixo hist?rico de aborto e n?o planejamento da gesta??o. Os resultados da An?lise Fatorial Explorat?ria com rota??o Oblimin, seguida de An?lise Fatorial Confirmat?ria para a vers?o de 16 itens e 13 itens (reduzida), indicaram bons indicadores de validade e confiabilidade para ambos modelos. Houve diferen?as na estrutura fatorial dos 2 modelos. A vers?o de 16 itens apresentou 5 fatores, a maioria organizados conforme a original. A vers?o reduzida se mostrou similar ao modelo original, por isso se indica seu uso. A escala presentou validade convergente, divergente e de construto confirmada pelas correla??es entre os fatores da CWS e os escores de estresse (convergente), autoestima e apoio social (divergente). A validade de crit?rio foi observada pelas diferen?as do valor total e fatores da CWS entre grupos de gestantes (prim?paras/mult?paras; adolescentes/adultas jovens/tardias). A confiabilidade avaliada atrav?s da consist?ncia interna da escala foi satisfat?ria (valor ?=0,825) bem como dos fatores (?=0,64-0,74). Os resultados psicom?tricos com rela??o ? validade e confiabilidade da vers?o brasileira da CWS indicam que a escala ? apropriada para ser utilizada. Instrumento ?til e de f?cil aplica??o que pode ser usado por pesquisadores e cl?nicos para avaliar preocupa??es de gestantes. / The Cambridge Worry Scale is a multidimensional scale created to evaluate the type and intensity of pregnant worry with good rates of validation and trustworthiness. This research?s main objective was to adapt and analyze the psychometric evidences of the Cambridge Worry Scale, which evaluates maternal worries on pregnant women. The specific goals were: a) adapt the semantic items in the Cambridge Worry Scale from English to Brazilian Portuguese b) evaluate content validation evidences through the content validation coefficient (stage 1); c) verify validation and trustworthiness elements of the Cambridge Worry Scale through psychometric evaluation procedures (stage 2). Transcultural adaptation of transversal cut done with 420 pregnant women from the age of 13 assisted in Basic Health Units in Natal (RN). It was used as instruments: 1) Structured quiz (socio-demographic and pregnancy data); 2) Cambridge Worry Scale (CWS); 3) Psychosocial profile in pre-birth (PPP); and the social support scale. The project fulfilled the ethnic aspects having a favorable juridical decision (572.558/ 2014) from the UFRN?s Ethics and Research Committee. The data analysis were done with the help from the SPSS (21.0) Software. On stage 1 descriptive statistics were done (frequency and validation coefficient of the content - CVC) and Kappa?s Fleiss calculus. On stage 2 we used the exploratory and confirmatory factorial analysis, t test, ANOVA, Pearson Correlation; and Cronbach?s alpha calculus. On stage 1 we had the formal authorization from the authors; preparation and consolidation of the preliminary version; and content validation about the Clarity criteria, Practical Pertinence and Theoretical Relevance, which CVCs were higher than 0.8 in most of the items. The Theoretical Dimension presented a substantial conformity (k=0.7164). Stage 2 refers to the collection of data from 420 pregnant women. The average age was 26.85 (?8,93) years old, most of them presented low education and income level, they were house wives, catholic, and married. Women with multiple kids predominated, low abortion rate history and there weren?t a pregnancy planning. The exploratory factorial analysis with Oblimin rotation, followed by the confirmatory factorial analysis for the 16 items and 13 items (reduced), pointed good validity indicators and trustworthiness for both models. There were differences in the factorial structure of both models. The 16 items presented 5 factors, most of them organized according to the original. The reduced version showed itself similar to the original model, and that?s why its usage is indicated. The scale presented convergent validation, divergent and confirmed construct by the correlation between CWS factors and stress scores (convergent), self-esteem and social support (divergent). The criteria validation was observed through the difference of the total score and factors of the CWS amongst pregnant groups (first pregnancy/multi pregnancy; teenagers and adults young/late). The evaluated trustworthiness through the internal consistency of the scale was good (valor ?=0.825) as so did the factors (?=0.64-0.74). The psychometric results regarding the validity and trustworthiness of the Brazilian version of the CWS points out that the scale is appropriate to use. It?s a useful and easy to apply instrument that can be used by researchers and clinics to evaluate pregnant worries.

The objectives of this research were to elaborate and to validate a scale of occupational stressors for employees of the production line, carrying out content validation, construct validation, convergent validation, precision evaluation and scale normalization. 214 employees were the participants of the research all of whom work in the production line of several companies of the Alto do Tiete region. The sample was divided in three groups (G1, G2, and G3). G1 was composed of 10 employees for a pilot study, G2 was composed of 214 employees for the validation of the scale and G3 was composed of 40 employees who participated in the retest. The materials used were a list with 41 stressors in the initial version of the scale, the scale of occupational stressors with 36 items already after the pilot study was carried out, the Job Content Questionnaire (JCQ) for the convergent validity and the Inventory of Symptoms of Stress Lipp (ISSL). Also, it made use of terms of consent and authorizations whenever necessary. The results demonstrated high and positive correlations in the precision of the scale (p < 0.01), tendency to the convergent validity (p < 0.01) validity of concurrent criterion (p<0.01 and p < 0,005). In relation to the normalization the results showed no evidence of significant differences between age and level of schooling and the scores of the scale of stressors. This demonstrates the universality and practicity, important in system of numerical counting. It was concluded that the scale of occupational stressors of production line presented high coefficient of precision, internal consistency e temporal stability and it was possible to reach the objective of content validity, construct and convergent validity, demonstrating to be capable of identifying occupational stressors of production line. The normalization needs new studies to be carried out with the scale, increasing the number of participants or carrying out a study with random sample, so that bias concerning norms and standardization does not occur. / As ci?ncias em geral necessitam cada vez mais de instrumentos que forne?am medidas objetivas e reprodut?veis.

It is known that this type of research requires the use of validated research instruments in order to ensure its quality and therefore the results obtained after its application in other studies. The analysis of the psychometric properties, reliability and validity of an instrument is critical to ensure that it is calibrated to measure the phenomenon to which it is proposed. Objective: to determine the psychometric properties of the Brazilian version of the inventory "Parcours des Jeunes Amourex" - Loving Trail Youth - PAJ through construct validation and reliability analysis. Methodology: methodological study which deals with the construct validity and reliability (psychometric analyzes) of the Brazilian version of the PAJ, executed in the period 2013-2015, using a convenience sample of 380 adolescents and young adults in the age groups 14-24 years enrolled in public schools in Feira de Santana, Bahia-Brazil. This research represents the second stage of cultural adaptation process and inventory of content validation, carried out from 2011-2013, which led to the national version (adapted and validated). The original inventory and the national version consist of 64 questions in different formats (dichotomous, open, scales). And reliability analysis was used examining the internal consistency of the questions, by calculating the Cronbach's alpha coefficient, considering the satisfactory value> 0.6; the factorability of the questions was evaluated by the test Kaiser-Meyer-Olkin Measure of Sampling Adequacy (KMO), with appropriate value> 0.5; the construct validity was verified through exploratory factor analysis using the principal component analysis technique, with varimax rotation, using the latent root criterion to define the number of factors to be extracted. Results: The data showed that the adapted version of the PAJ has construct validity of evidence, since the measures proposed construct and has adequate reliability coefficients, confirming the internal consistency of the scale. It can be said then that the inventory showed good psychometric parameters allowing its applicability in national studies that seek to investigate violence among young couples and factors related to family life and friends. Conclusions: This research contributes to the appropriateness and applicability of an inventory that assesses multiple dimensions of loving violence in youth, encouraging new studies, exchange of information between different contexts, and can support public policies and programs that lead to the prevention and cure cycle intergenerational victimization and aggression between present and future generations. / Introdu??o: em n?vel mundial, reconhece-se a import?ncia dos estudos transculturais para estudar fen?menos abrangentes, multifacetados e multicausais, como a viol?ncia interpessoal entre jovens, considerando o impacto dos indicadores dessas pesquisas nas trocas de conhecimentos e a??es voltadas ? preven??o e controle dos fatores de risco e vulnerabilidades.
