What is self-report in measuring non-adherence?
It involves patients completing questionnaires about their adherence to treatment, such as the Medication Adherence Report Scale (MARS).
What format does the Medication Adherence Report Scale (MARS) use?
A forced-choice yes/no format.
List three advantages of using self-report to measure adherence.
It is cheap, quick, and can collect data from a large number of people, increasing generalizability.
What are two main disadvantages of self-report methods?
They rely on patient memory (reducing reliability) and are subject to social desirability bias (reducing validity).
What is a semi-structured clinical interview in the context of non-adherence measurement?
A focused dialogue between the patient and practitioner designed to elicit details about adherence.
What is the Medical Adherence Measure (MAM)?
A tool designed to obtain adherence details from patients through clinical interviews.
Why is the success of a semi-structured interview dependent on the patient-practitioner relationship?
Patients are more likely to be honest if they feel comfortable with the practitioner.
What are two strengths of semi-structured interviews in adherence research?
They provide detailed qualitative data, increasing validity and usefulness.
List three disadvantages of semi-structured interviews.
They are time-consuming, expensive, and have a high drop-out rate, leading to lower generalizability.
What was the aim of Riekert and Drotar’s (1999) study?
To assess the implications of non/incomplete participation of adolescents with diabetes in treatment adherence research.
What was the sample size of the study?
Initially 94 families, but only 52 completed the study.
What method did the researchers use to assess adherence?
The Adherence and IDDM Questionnaire-R, interviews, and monitoring blood glucose levels using a reflectance meter.
What were the main findings of Riekert and Drotar’s study?
Adolescents who did not return questionnaires had significantly lower adherence than those who completed them.
What was the main conclusion of the study?
Lower adolescent adherence is associated with lower participation in adherence research.
How is pill counting used to measure adherence?
Patients bring their medication to the clinic, where the remaining pills are counted.
How can unannounced pill counts improve validity?
By conducting telephone or home visits, researchers can prevent patient manipulation of pill counts.
What study supports the validity of pill counting?
Kalichman et al. (2008) found a 92% agreement between telephone/home pill counts and viral load measures in HIV+ patients.
What are two disadvantages of pill counting?
It is burdensome for patients who must bring medication to appointments, and patients may manipulate the pill count if they know the date and time.
What are medication dispensers
and how do they work?
What is a major advantage of medication dispensers for patients?
They serve as reminders, reducing forgetfulness and preventing relapse.
Why do medication dispensers lack validity in adherence measurement?
Just because a pill is removed does not mean it has been taken.
What type of non-adherence do medication dispensers help reduce?
Unintentional non-adherence caused by forgetfulness.
What was the aim of Chung and Naya (2000)?
To electronically assess compliance with an oral asthma medication.
What technology did they use to track medication adherence?
TrackCap, which recorded the date and time the pill bottle was opened.
