Research: Treatment Adherence & Treatment Differentiation

Treatment adherence consists of 2 components:

  1. Treatment Adherence : degree in which the treatment is conducted in accordance with the theoretical model and prescribed technique.
  2. Treatment Differentiation: degree in which different treatments differ in the intended direction with respect to therapeutic interventions (e.g. comparative outcomes).
