|What types of clients can the tool be used for?||The BIT can be used with, but is not limited to clients with stroke.|
|Is this a screening or assessment tool?||Assessment|
|Time to administer||The BIT takes 30 to 40 minutes to administer|
|Versions||BIT; BIT shortened version|

– No studies have examined the intra-rater reliability of the BIT.
– Two studies have examined the inter-rater reliability of the BIT and reported excellent inter-rater reliability using Pearson correlation coefficient.
|Floor/Ceiling Effects||No studies have reported floor/ceiling effects of the BIT in clients with stroke.|
|Sensitivity/specificity||One study examined the specificity and sensitivity of the BIT and reported that both subtests are able to accurately identify individuals with visual neglect.|
|Does the tool detect change in patients?||No studies have reported the responsiveness of the BIT in clients with stroke|
|Acceptability||The tests are easy and simple to administer.|
|Feasibility||The tests are easy to administer, simple and relatively unambiguous to score, and are sufficiently wide ranging to detect different forms of visual neglect.|
