The second study reviews the internal consistency of the Behavioral Inattention Test (BIT) and the CBS on 51 people. Both of them were assessed with high reliability. The third and fourth study test the reliability of the Occupational Therapy Adult Perceptual Screening Tests (OT-APST). The fourth study is all about the inter-rater reliability of the Clock-drawing Item.
