What was measured

The Adherence Starts with Knowledge Scale (ASK-12) will be used to assess the likelihood that a patient is taking oral medications per protocol. The 12-item questionnaire was derived from the predecessor ASK-20 using a study population of 112 patients with asthma, congestive heart failure or diabetes. In this study, the ASK12 had good internal consistency, and test-retest reliability. The ASK-12 which elicits the same type of information as the Morisky Medication Adherence Scale (MMAS) also demonstrated convergent validity through strong correlation with MMAS-4 (Spearman correlation r = 0.74; p \< 0.001). The ASK-12 titled 'Taking Medicine What Gets in the Way?' is segmented into 3 sections: inconvenience/forgetfulness (3 items), treatment beliefs (4 items) and behavior (5 items). Response for each item is on a 5-point Likert scale (1-5) with the total score ranging from 12-60 and a higher score representing less likelihood of medication adherence.
