RCT-PQRS = Randomized Controlled Trial of Psychotherapy Quality Rating Scale.24
a
The total quality-of-study score is obtained by summing items from #1 to #24 and ranges from 0 to 48. A total quality-of-study score equal or greater than 24 corresponds to the minimum adequate study quality.23
b
The omnibus score, which coincides with item #25, ranges from 1 (exceptionally poor study) to 7 (exceptionally good study).
