[Cultural scale adaptation and validation of the Spanish version of the BRCA Self-Concept Scale in @entity1 carriers at high risk for XXXX ].

@entity1 @entity5344 @entity3355 @entity5 @entity3795
BACKGROUND AND OBJECTIVE: Having an inherited predisposition to @entity5 may have a @entity3355 , and one goal of genetic counseling is to promote psychological adjustment to the new situation. Thus, in the genetic context, validated measures of adjustment are required. Given that self-concept is a good indicator of adjustment to the disease or to the risk for it, and a relevant variable in oncology, the goal of the study is to culturally adapt and validate the BRCA Self-Concept Scale. MATERIAL AND METHOD: One hundred and sixty-five BRCA carriers' @entity1 answered to the questionnaire, previously adapted through a process of forward/back-translation, and to the @entity5 ( @entity5 ) as a measure of convergent validity. Theoretical structure of BRCA Self-Concept Scale was assessed by expert judges, and submitted to a confirmatory factor analysis ( @entity3795 ). Cronbach's a was calculated for each subscale (Stigma, Vulnerability and Control), and correlations with @entity5 were performed. RESULTS: Expert judges' structure and @entity3795 do not support the original structure of the questionnaire. The respecificity model (with items 10 and 13 loading on Vulnerability factor) show a better fit: comparative fit index 0.973; Tucker-Lewis index 0.968; root mean square error of approximation 0.067. The Cronbach's a is 0.83 for Stigma, 0.84 for Vulnerability, and 0.61 for Control. Evidence of convergent validity with @entity5 has been obtained (Spearman's rho 0.631 for Stigma, 0.683 for Vulnerability, and -0.363 for Control; P<.001). CONCLUSIONS: Results support the validity of the modified Spanish BRCA Self-Concept Scale, which is a potentially useful measure for the study of psychological adjustment to high risk for @entity5344 .
