Description of intervention(s) / exposure
Cognitive interviews will be conducted with 25 participants, in order to gain feedback about the newly developed Anticipated Adherence Index (AAI). This novel scale aims to measure adherence to medication, prior to medication initiation.

The cognitive interviews will be in-person at the Auckland University Clinical Research Centre. Each participant will be asked to complete one, 45 minute appointment. These interviews will be conducted by the student researcher.

The 'think aloud' cognitive interviewing procedure developed by Willis (2007) will be utilised during the interview. In this protocol, participants are provided with a training question to introduce them to the think-aloud protocol. This protocol asks participants to verbally respond to each item, and also verbalise their thought processes that led to their response. An audio recording of the participant's verbal think-aloud stream will be taken to capture the nuances in each subjects answer. These will be transcribed following each interview. Thematic analysis will be utilised to identify the main themes related to each item. This information will be used to adapt the Anticipated Adherence Index with the wider research team

Outcomes
Primary outcome [1] 331455 0
Qualitative responses to the Anticipated Adherence Index (AAI) items will be collected by using one-on-one, face 45-minute interviews. These interviews will be utilising the Cognitive Interviewing protocol. These interviews are semi-structured, and will be audio-recorded.
Timepoint [1] 331455 0
During the interview period.
Secondary outcome [1] 409956 0
Preliminary content validity of the AAI will be determined, by assessing whether the intended content measured in each item, was relevant to the theme output of the thematic analysis.

For example, if an items main focus is self-efficacy within the AAI, then the qualitative output will be analysed to determine if self-efficacy was a theme among the responses to that item.
Timepoint [1] 409956 0
Cumulative responses will be assessed at the conclusion of the interview period.
