Adherence & Retention
Different ways to score adherence questions
Hi!
I have used ACTG questions to ask patients about adherence:
- missed pill last week-end
- how often spend >1 day without pills at all in pill box
- missed any pharmacy visit last 6 months
- if yes, how many visits
- missed any clinic visit last 6 months
- if yes, how many visits
- When was the last time you missed taking any of your ARVs at all.
I know Reynolds N et.al. suggested a formula to use, but I didn't
cover all the questions in that formula.
I scored the questions as 0 good adherence up to highest number
(depends on answers for each question) and a high number will be poor
adherence. Tried to use median level but not sure it will be useful?
Any tips or suggesting any refs will be much appreciated.
Thank you and best regards

Dear Ziad, the classic ACTG measure paper is: Self-reported adherence to antiretroviral medications among participants in HIV clinical trials: the AACTG Adherence Instruments; by Chesney, M. A., Chambers, D. B., Ickovics, J. R., Gifford, A. L., Neidig, J., Zwickl, B., Wu, A. W.; AIDS Care; Jun2000, Vol. 12 Issue 3, p255, 12p (abstract available on Pubmed here: http://www.ncbi.nlm.nih.gov/pubmed/10928201) and the recent work from Ira Wilson that suggests rating scales may also be informative (Optimal Recall Period and Response Task for Self-Reported HIV Medication Adherence, AIDS and Behavior): http://www.ghdonline.org/adherence/resource/optimal-recall-period-and-respons...
Does anyone else have additional tips and refs to suggest? Please share with the community.
Best, David
