Objective: Validate the Caring Efficacy Scale and Nyberg's Caring Assessment. Both these elements are based on the Theory of Transpersonal Human Caring, which is founded on the humanistic and ethical aspects of care. Method: These scales were validated in a sample comprised of 30 Chilean nurses. Cronbach's alpha was 0.76 for the Caring Efficacy Scale and 0.82 for Nyberg's Caring Assessment. In terms of construct validity, both instruments are correlated positively and significantly. Results: Divergence is weighted as a strategy or approach to this validity in both instruments, and a subscale was used to evaluate lack of empathy with the suffering of others. Conclusion: The validation of these scales is a contribution to transpersonal human caring in terms of knowing the significance nurses give to it and how effective they feel, as well as to remedy shortcomings in the teaching and practice of human care.
