Items with a mean of greater than 4.00 or less than 2.00 indicated and standard deviation less than 1.00 indicated inadequate variability.Items with a mean of greater than 4.00 or less than 2.00 indicated skewness, and standard deviation of less than 1.00 indicated inadequate variability. For the importance scale, the items means were ranged from 2.84 to 3.78 which showed a midrange sense of not important / important in all statements. The data from the 32 pharmacists was used for the internal consistency. The internal consistency coefficient of importance scale was 0.868 and there were 15 items in scale.
