For the target audience (pre-test), 89.3% of agreement and Content Validity Index of 0.89 were obtained. Construct validity had a total explained variance of 73.8%. The concurrent criterion validity presented a correlation coefficient (ρ) of 0.75 (p = 0.004). Reliability had a Cronbach’s α coefficient of 0.82 for the full scale and a range of 0.62 to 0.82 in the instrument’s goals.
