RELIABILITY AND VALIDITY OF THE RUTGERS PSYCHOTHERAPY PROGRESS SCALE

The Rutgers Psychotherapy Progress Scale (RPPS) was designed to measur e goodness of client process as this concept is described in the psych oanalytic literature, The RPPS was applied to every other 5-minute blo ck of material in the transcripts of two complete, brief(14-16 session ) psychodynamic therapies that had different outcomes. The cases were 21- and 30-year-old females suffering from anxiety and relationship di fficulties, ?he scale had adequate interrater reliability and internal consistency based on the average of 4 raters' scores. Regarding predi ctive validity, 6 of the 8 items and the total score were higher fur t he case with the better outcome, Concurrent validity was demonstrated in that 6 of the 8 items and the total score correlated as predicted w ith the Vanderbilt Psychotherapy Process Scale. The results were seen as providing preliminary support for the reliability and validity of a 6-item version of the scale.
