This measure is designed to support rapid identification of barriers to following a prescribed treatment plan. The Treatment Adherence Factors Scale is a brief self-report questionnaire intended to characterize factors that may influence a patient’s engagement with treatment recommendations.
The instrument includes 12 items and typically takes about 3 minutes to complete. In a neutral, structured format, it can be used to screen for domains that may contribute to nonadherence (e.g., beliefs about treatment, perceived relationship with the provider, or practical constraints), to inform discussion and targeted clinical follow-up. Authorship is attributed to C. Everett Koop.
Interpretation of results should be integrated with clinical interview and relevant contextual information, rather than used as a stand-alone indicator of adherence. When used in this manner, the Treatment Adherence Factors Scale can help guide individualized problem-solving and planning to address modifiable adherence-related factors.
