Brief summary

Adherence to medications is integral for the management of both chronic and acute conditions, yet, in order to understand adherence behaviours, measurement is critical. Currently, there is no measure which allows for intentions to adhere to be assessed prior to medication initiation. Therefore, the Anticipated Adherence Index (AAI) is a newly developed scale in order to determine intentions to adhere prior to medication initiation. This study aims to provide initial validation via quantitative data. This study is a cross-sectional design with a 2-week follow up to initially administer the newly developed Anticipated Adherence Index (AAI). Participants will be recruited from various community pharmacies in Auckland, and provided with a flyer by the pharmacist which will give a brief description of the study along with the QR code and link to complete the study. In order to complete the study, participants will be required to read a participant information sheet, have the opportunity to ask the student researcher any questions via email, and fill out an eligibility questionnaire. If eligible, participants will be required to fill out brief demographic information, and complete the Anticipated Adherence Index (AAI). All of these steps will be completed via the Qualtrics platform. Following their prescription period (or two-weeks post initial measurement), participants will be asked to fill out the Brief Adherence Rating Scale, and repeat the AAI measure via Qualtrics. The study outcomes will allow for further refinement of the AAI through statistical analysis and provide initial reliability and validity estimates.

Interventions

In order to understand adherence to medications, measurement is critical. Therefore, this study is the first to provide qualitative data in order to validate the newly developed Anticipated Adherence Index. Potential participants will be given a small flyer about the study when they attend a pharmacy to collect a prescription. This flyer will be given to them by the pharmacist, and includes brief information about the study. Participants will be asked to complete the Anticipated Adherence Inde

In order to understand adherence to medications, measurement is critical.

Potential participants will be given a small flyer about the study when they attend a pharmacy to collect a prescription. This flyer will be given to them by the pharmacist, and includes brief information about the study. Participants will be asked to complete the Anticipated Adherence Index via the online Qualtrics platform. This will take an average of 15 minutes for each participant to complete. Following completion of the survey, a window will pop up thanking them for their time, and reminding them about the follow-up measure in two-weeks time. Two-weeks post initial measurement, participants will be asked to repeat the Anticipated Adherence Index (AAI) and the Brief Adherence Rating scale via Qualtrics. This will take around 15 minutes to complete & will enable researchers to determine whether adherence intentions prior to medication initiation was reflected by actual self-reported adherence during the two-week period. Following completion of the two-week follow-up, participants will be thanked for their time, and be told that they are now in the prize-draw for a $500 voucher.
