AB  - OBJECTIVE: To determine the minimal clinically important difference (MCID) for a 
      Rasch measure derived from the Irritability/Lability and Agitation/Aggression 
      subscales of the Neuropsychiatric Inventory (NPI)-the Rasch NPI Irritability and 
      Aggression Scale for Traumatic Brain Injury (NPI-TBI-IA). DESIGN: 
      Distribution-based statistical methods were applied to retrospective data to 
      determine candidates for the MCID. These candidates were evaluated by anchoring 
      the NPI-TBI-IA to Global Impression of Change (GIC) ratings by participants, 
      significant others, and a supervising physician. SETTING: Postacute 
      rehabilitation outpatient clinic. PARTICIPANTS: 274 cases with observer ratings; 
      232 cases with self-ratings by participants with moderate-severe TBI at least 6 
      months postinjury. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: 
      NPI-TBI-IA. RESULTS: For observer ratings on the NPI-TBI-IA, anchored comparisons 
      found an improvement of 0.5 SD was associated with at least minimal general 
      improvement on GIC by a significant majority (69%-80%); 0.5 SD improvement on 
      participant NPI-TBI-IA self-ratings was also associated with at least minimal 
      improvement on the GIC by a substantial majority (77%-83%). The percentage 
      indicating significant global improvement did not increase markedly on most 
      ratings at higher levels of improvement on the NPI-TBI-IA. CONCLUSIONS: A 0.5 SD 
      improvement on the NPI-TBI-IA indicates the MCID for both observer and 
      participant ratings on this measure.
