Treatment Adherence Factors Scale Test

People managing prescribed medication can use the Treatment Adherence Factors Scale Test to examine why following a regimen may feel straightforward, inconsistent, or difficult. It is intended for readers who want to identify factors that may affect adherence and prepare more focused conversations about treatment. As a medication adherence assessment, it turns everyday experiences into an overall profile without requiring specialized psychological knowledge.

What This Assessment Measures

Items examine medication purpose, perceived benefit, dosing convenience, treatment burden, safety concerns, cost, access, forgetfulness, and feeling well as a factor that may affect adherence. These influences span practical, cognitive, emotional, and situational experiences.

The test functions as a treatment adherence questionnaire with three thematic areas:

• Understanding and perceived benefit show how purpose, results, or feeling well may affect adherence.
• Regimen burden covers continuous use, dosing inconvenience, multiple medicines, and medication changes.
• Safety, access, and memory barriers include side-effect or dependence concerns, cost, consultation difficulty, and forgetfulness.

One overall scale reports the result: Treatment Adherence Scale (0-50). Low adherence is 0-21, Moderate adherence is 22-45, and High adherence is 46-50. The items ask about influencing situations, while the scale reads the resulting adherence tendency: higher scores indicate greater adherence, lower scores indicate significant barriers, and midrange scores may reflect partial adherence with specific difficulties.

Methodology and Evidence Base

Each item describes a possible influence and offers five ordered responses, from no effect through slight, occasional, frequent, and very frequent influence. The response task is consistent: judge how much the factor affects treatment-taking. This is current self-observation, not performance testing or clinician-rated data. Together, the items address everyday reasons for difficulty or inconsistency in treatment-taking.

The structure is conceptually consistent with the Adherence Barriers Questionnaire (Müller et al., 2015), which examines contributors to medication-related non-adherence; this questionnaire is not an adaptation of that instrument. Its practical-obstacle emphasis is also compatible with the MPRAQ developed by Chan et al. (2021). The WHO adherence framework places these factors within interactions among social and economic, health-system, condition-related, therapy-related, and patient-related influences.

The questionnaire produces one overall result, and the transformation from the five response options to that result is not specified. It can organize medication adherence barriers for discussion, but self-report is influenced by current health, memory, expectations, and willingness to disclose; the result describes a reported pattern, not proof of actual medication use or a diagnosis.
