RFT therapists
would report stronger adherence to FT techniques than to
techniques associated with the three alternative EBPs, and also,
they would report a higher FT adherence level than that reported
by TAU therapists. The final hypothesis is a flexible application of
treatment differentiation analyses suitable for hybrid process
cognitive-behavioral therapy, motivational interviewing, and drug counseling. Implications for rigorous
fidelity assessments of evidence-based practices in usual care settings are discussed.
