Table 3 Comments in favour of inclusion of these outcome domains, and other general discussion points, as extracted from the consensus meeting discussions

Impact on social situations

● “Thoroughly covers quite a few other outcome domains, it encapsulates social situations and captures the positives as well as negatives which is important according to the groups’ discussions. Quite a few things can be captured with a single measure”

● “The social situations outcome domain covers whether someone knows when to stop talking and all of this is captured within this domain of social situations”

● “This outcome domain covers ‘Listening effort’ too”

● “Definition relates particularly to situations where a lot of effort is required, effort is a key part of the definition, there is an overlap between ‘Listening effort’ and ‘Impact on social situations’, therefore ‘Listening effort’ was not identified as a domain to be in [the core outcome domain set] on its own right”

● “For me it is about the social situations, it is about family, friends, relationships, when having a few pints down the pub, for me as someone with SSD is about the social side of things”

Group conversations in noisy social situations

● “Provides a good real world example of complex listening and where people with SSD generally have a challenge”

● “One of the hardest speech related tasks so it’s an appropriate outcome measure, and in particular thinking about the devices, e.g., a cochlear implant has a speech processor, it promotes better speech comprehension”

● “This outcome domain captures ‘Listening in complex listening situations’ too”

Spatial orientation

● “Covers more than ‘Sound localisation’, more about the person, more valid: knowing which direction sounds is coming at you from. ‘Sound localisation’ is captured in orientation”

● “More valid for real world situations e.g., car in the street, walking across the road, and covers ‘Sound localisation’ as well”

● “Good fit because the definition includes a safety aspect to it, because it’s about where you are in the world, that is an important aspect of spatial orientation”

● “Covers outcome domain ‘Being aware of a sound’”
