The Mini Inventory of Right Brain Injury (MIRBI­-2) efficiently screens clients for neurocognitive deficits associated with right hemisphere lesions.

Ages: 20 through 80
Testing Time: 25 to 30 minutes
Administration: Individual

The MIRBI-2, now in its second edition, test's development meets the need for a brief, standardized, right-brain injury screening instrument that yields severity levels for deficit areas. Test reviews and professionals’ comments from the field were incorporated into the new edition.

Features of the MIRBI-2

• More data were collected on normal and right- and left-brain-injured individuals.
  
• The number of cases in the interscorer reliability study was increased and relevant analyses were conducted on the expanded dataset.
  
• Many new validity studies have been conducted, with particular emphasis on the relationships of MIRBI­-2 scores to other measures of neurocognitive impairment.
  
• A principal components factor analysis was performed to test construct validity of the items.
  
• Each item in the test was reevaluated using conventional item analysis to establish the underlying statistical foundation.
  
• A revised Right-­Left Differential Scale was created with an updated cutoff score for right-brain impairment.
  
• A table for converting raw scores to percentiles and stanine scores was added.
  
• The rationale has been updated to reflect current trends in neuropsychology.
  
• The test booklet was revised to include more user-friendly areas for recording patient information, as well as revised criteria for scoring patient responses.
  
• A tear-off response pad has been added for additional convenience, featuring a response sheet for items 1 and 2 on one side, and the Reading Ability paragraph for completion of items 7 and 8 on the other.
  

MIRBI-2 Reliability and Validity

The MIRBI-­2 was normed on 128 right-brain injured people. Reliability was estimated by coefficient alpha (.84). All item discrimination coefficients exceeded .3 acceptable levels and ranged from .37 to .81, median: .57. Inter-rater reliability was .99. Concurrent validity was very good and included the study of left-brain injured participants and control participants without brain injury.

• Examiner's Manual
• 25 Examiner Record Booklets
• 25 Report Forms
• 25 Response Sheets
