This thesis represents the transcultural adaptation of the Cambridge Worry Scale CWS with the main goal to adapt and seek psychometric evidences of the CWS, which evaluates maternal worries. The specific goals were: a) do the semantic adaptation of the CWS items from English to Brazilian Portuguese; b) evaluate evidence of the content validation through the content validation coefficient (stage 1); c) verify validation elements and trustworthiness of CWS through the psychometric evaluation procedures (stage 2). Transversal research with 420 pregnant with the age of 13 and forward watched in health basic units in Natal (RN). The Pregnant had an average of 26.85 (±8,93) years, the majority of them presented low income and educational level, they were Housewives and lived in a stable union. It was predominantly multi-labors with few abortions and non-pregnancy planning. We used as instruments: 1) structured survey; 2) Cambridge worry scale; 3) stress and self-esteem subscales of the psychosocial profile on the prebirth (PPP) and 4) social support scale. On the first stage descriptive statistics took place (frequency and content validation coefficient - CVC) and the use of Fleiss Kappa. On stage 2 explanatory and confirmatory factorial analysis were used, test t, ANOVA, Pearson correlation and Cronbach Alpha. On stage 1 we had the formal authorization of the authors, preparation and consolidation of then preliminary version, and content validation regarding the Clarity criteria, Practical Pertinence and Theoretical Relevance, with the majority of items with CVCs higher than 0,8. The Theoretical Dimension presented substantial concordance (k=0.7164). On stage 2 the results of Factorial Explanatory analysis (Oblimin), followed by factorial confirmatory analysis for the 16 items version and 13 items (reduced) presented good validation and trustworthiness rates for both models. However the reduced version presented itself similar to the original model with 4 factors, considering it more suitable. The convergent and divergent validations were done with stress, self-esteem and social support. The criteria validation with pregnancy groups (age/parity). The evaluated trustworthiness by the internal consistency was satisfactory (value α=0.825/scale). Therefore the Brazilian version of the CWS presented good rates of validation and trustworthiness, and it can be used by researchers and clinical to evaluate pregnant worries.
