Retest reliability coefficients with a one week interval for the 16 primary and 5 secondary scales of 16 PF-E were calculated for a sample of 100 rehabilitation clients. The primary scale reliabilities ranged from .43 to .78, with a median of .68. Three secondary scale reliabilities were in the low .70s and two were in the .80s. It was concluded that the primary scales of 16 PF-E should be used with extreme caution and counseling applications should focus on the secondary scales.
