Abstract

© 2018, Universidad Complutense de Madrid. All rights reserved. Purpose: The aim of this study was to analyze the reliability and validity of the spanish adaptation of the Perceived Personal Control (PPC) scale in women who were positive for BRCA1/2 genes, which are related with hereditary ovarian and breast cancer (HOBC). Method: PPC original items developed by Shiloh and co-workers were translated and back-translated in order to develop an spanish version which was analyzed by an exploratory factor analysis with Oblimin rotation. Answers to the spanish version were provided by a sample of 176 women who were positive for BRCA1/2 for HOBC. Results: Spanish version contains only six items of the nine original items, since this structure provided the optimal solution to the exploratory factor analysis. This version is a one-factor scale (51.07% of variance explained) and all items had factor loading values >0.4. The scale has good reliability (Cronbach’s Alpha =0.84) and gives a range of values between 0 (low perceived control) and 2 (high perceived control). Conclusions: Spanish adaptation (PPC6) of the original 9-items version has enough reliability and psychometric properties, and it seems to be useful to be applied in Genetic Counseling at spanish cultural settings.
