Key, X on this date; (X)—may take place/follow on, on this date; A—abbreviated intervention participants only; (A)—may take place/follow on at this date for abbreviated intervention participants.

*This details the process for the full intervention. The ‘abbreviated’ intervention will complete at week 3 with follow up assessments and follow-up interviews at week 4/5. The order of the SSI is flexible, depending on time to receive sensory equipment and participant’s needs.⁶⁰

†Ophthalmological and audiological assessments will be conducted based on positive screening results. Not all participants will receive full clinical hearing and vision screening, if not required. Hearing aids and glasses are prescribed if deemed necessary by clinical assessment. Not all participants may require both hearing aid and glasses.

‡There may be a longer duration than 1 week between prescribing a hearing aid and receipt of hearing aid, depending if instant fit or moulded fit. The SST will undertake SSI visits during this time on weekly basis.

§Revisit and recap: these additional weeks of intervention allow for the SST to revisit and recap any of the previous components in more depth and to work on goal-setting and achievement activities with the person with dementia and study partner.
