This scale assesses the patient’s expectancy for improvement after treatment in relationship
to a specific treatment.24 It consists of an 11-point scale varying from 0 to 10, in which 0 represents “no expectancy for improvement” and 10 represents “expectancy for the greatest possible improvement.” 24 This scale will be administered only on the first day of assessment
(baseline) before the randomization. The reason for including this scale is to analyze whether the expectation of improvement will influence the outcomes.
