Previous issue date: 2016-08-12 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / A Cambridge Worry Scale ? uma escala multidimensional elaborada para avaliar o tipo e
a intensidade da preocupa??o de gestantes com bons ?ndices de validade e confiabilidade.
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.
