• Description:
  Background:
  
  The Life Impact Burn Recovery Evaluation (LIBRE) Profile© was developed using Item Response Theory methods to assess social participation after a burn injury. The LIBRE Profile measures six areas of social participation: Relationships with Family & Friends, Social Interactions, Social Activities, Work & Employment, Romantic Relationships, and Sexual Relationships. It can be administered through a computerized adaptive test or through fixed short forms. The goal of this study was to further examine the psychometric properties of the LIBRE Profile, including reliability and validity.
  
  Methods:
  
  We examined the validity of the LIBRE Profile by administering the six LIBRE Profile scales as well as legacy measures that assessed similar constructs. We calculated the Pearson correlations between the LIBRE Profile scales and the scores on the same-domain and crossdomain legacy measures to evaluate convergent and divergent validity. We then administered the LIBRE Profile scales a second time, seven to ten days after the first administration, to a sample of adult burn survivors to evaluate test-retest reliability. We calculated repeatability coefficients, standard error of measurement, and minimal detectable change to establish the threshold beyond which the amount of change observed across an episode of care cannot be explained as measurement error.
  
  Results:
  
  For reliability, the repeatability coefficients ranged from 7.31 to 9.27 and SEMs ranged from 2.62 to 3.39 for all six scales. MDC90 values ranged from 6.08 to 7.86 points, and MDC95 values ranged from 7.26 to 9.40 points. All correlations between the LIBRE Profile scales and legacy measures are significant (p < 0.05) and in the expected directions for both convergent and divergent validity.
  
  Conclusions:
  
  This study provided evidence for the reliability and validity of the LIBRE Profile, one of the first tools that measures exclusively the social participation after a burn injury.
