Nursing professional values: validation of a scale in a Spanish context.

Purpose: To validate culturally the "Nursing Professional Values Scale: NPVS-R" for use in Spain.

Methods: We used the forward and backward translation method with complementary qualitative methodology. We first formed discussion groups to detect cultural differences, then set up a multidisciplinary group to ascertain the equivalence or discrepancies between the English and Spanish versions and to decide on the final pre-test version.
