title: Goal attainment scaling in the rehabilitation of patients with lower-extremity amputations: a pilot study.
abstract: OBJECTIVE
  To assess the interrater reliability, construct validity, and responsiveness of Goal Attainment Scaling (GAS) among patients who have had lower-extremity amputations.
  
  
  METHODS
  Pilot study comparing GAS with 2 functional measures with established reliability, validity, and responsiveness values.
  
  
  METHODS
  Regional amputee program in southwestern Ontario.
  
  
  METHODS
  Ten patients (6 women, 4 men; mean age +/- standard deviation, 72.3+/-10.7 y) with unilateral lower-extremity amputations who were consecutively admitted to a regional amputee program. The ratio of transtibial to transfemoral amputations was 6:4.
  
  
  METHODS
  Not applicable.
  
  
  METHODS
  Subjects were assessed by using GAS, the Barthel Index, and the Locomotor Capabilities Index (LCI) of the Prosthetic Profile of the Amputee.
  
  
  RESULTS
  The interrater reliability of GAS was r=.67, and 63% of goals developed were identified independently by both investigators. The construct validity between GAS and the Barthel Index and the LCI was r=.44 and r=.35, respectively. GAS was more responsive than both the Barthel Index and the LCI, as indicated by the calculation of effect sizes and relative efficiencies.
  
  
  CONCLUSIONS
  This pilot study suggests that GAS is a promising outcome measure for the rehabilitation of patients with lower-extremity amputations.
