Development of the purposeful action medication-taking questionnaire.

This three-phase study describes the development and psychometric properties of the Medication-Taking Questionnaire (MTQ) to measure the purposeful action domain (reasons individuals decide to accept medication treatment) in the medication adherence model for hypertension. During Phase I, items were evaluated for content validity and clarity. Item analysis, internal consistency, and exploratory factor analysis were preformed during Phase II to finalize the MTQ: Purposeful Action as 12 items and 2 subscales (treatment benefits and medication safety). Phase III evaluated the MTQ: Purposeful Action for temporal stability and construct validity. The final version MTQ: Purposeful Action demonstrated good internal consistency, temporal stability, and construct validity. The MTQ: Purposeful Action appears to have good psychometric characteristics that represent the decision-making process for adherence in medication treatment for hypertension.

The Medication Adherence Model: a guide for assessing medication taking.

The Medication Adherence Model (MAM) was developed to describe the process of medication adherence and guide health care providers in assessing medication-taking in individuals with hypertension. The MAM was structured with the idea that two types of nonadherence contribute to inconsistent medication taking, the intentional decision to miss medications, and the unintentional interruptions that cause medications not to be taken. The three core concepts identified in the model are: (a) Purposeful Action, (b) Patterned Behavior, and (c) Feedback. Patients' initiating and sustaining medication adherence are dependent on the deliberate decision to take medications based on perceived need, effectiveness, and safety (Purposeful Action). Then they establish medication-taking patterns through access, routines, and remembering (Patterned Behavior). Individuals use information, prompts, or events (Feedback) during the appraisal process to evaluate health treatment that, in return, influences individuals' levels of Purposeful Action and Patterned Behavior (Johnson, 2002; Johnson, Williams, & Marshall, 1999). The MAM depicts the dynamic process of initiating and maintaining medication adherence from the hypertensive patient's perspective. The model describes the key components of existing cognitive and self-regulatory models, and identifies an additional behavioral component. The succinct organization of the MAM may facilitate health care providers' ability to evaluate and individualize interventions for promoting medication taking.
