Materials and methods: A descriptive study, where the Spanish adaptation published in 2009 was sent to three experts, to subsequently identify the acceptability index. Results: the overall acceptance rate of 0.85 is considered good, showing a lower rate on the dimension B and higher in D, with 100% agreement in 66.66% of the items studied. Conclusions: The cultural validation of the test is presented with a good index of acceptability for clinical practice.
