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.
