SENSE-Cog sensory support intervention field study primary outcomes measures and methods to capture outcomes

Field study outcome	Method to capture outcome
PwD effort	In-house rating scale in PwD and SP diaries; semistructured interview with both dyad members
PwD fatigue
PwD motivation
PwD engagement
PwD understanding
Frequency/duration of SSI sessions	SST diary
SSI feasibility	Completion rates/missing data at baseline and follow-up
Is SSI delivered as intended?	SST diary checklist after each visit
Is SSI received as intended?	Records of contact between SST and recipient. This will include information on: number and duration of contact, sessions; method; referrals and protocol deviations. PwD and SP will have their knowledge of the SSI components checked by the SST
Is SSI enacted as intended?	SST, PwD, SP diaries; semistructured interview
Reach	Proportion of referred patients who enter the study
Recruitment	Number of patients approached versus number recruited
Retention	Number of participants withdrawing and reasons
Screening	Number of patients screened ‘suitable’ versus ‘unsuitable’
Inclusion/exclusion criteria	Feedback from CRN/other recruiters about ease of screening criteria
Assessment of impairment and corrective device delivery and fitting	SST, PwD, SP diaries; feedback from research team and industry partners
Functional assessments	SST, PwD, SP diaries; analysis of frequency of missing data
‘Logistics circuit’ of hearing/vision assessments and devices	SST, PwD, SP diaries; feedback from research team and industry partners
SST training	SST diary will identify areas of training for the role
SST visits	SST, PwD, SP diaries; semistructured interview
Glasses usage
Hearing aid usage
Receptivity to sensory equipment
Helpfulness of SSI
Motivation to continue with SSI activities
