Abstract
Objective
To develop self-reported short forms for the Life Impact Burn Recovery Evaluation
(LIBRE) Profile.
Design
Short forms based on the item parameters of discrimination and average difficulty.
Setting
A support network for burn survivors, peer support networks, social media, and mailings.
Participants
Burn survivors (N=601) older than 18 years.
Interventions
Not applicable.
Main Outcome Measures
The LIBRE Profile.
Results
Ten-item short forms were developed to cover the 6 LIBRE Profile scales: Relationships
with Family & Friends, Social Interactions, Social Activities, Work & Employment,
Romantic Relationships, and Sexual Relationships. Ceiling effects were ≤15% for all
scales; floor effects were <1% for all scales. The marginal reliability of the short
forms ranged from .85 to .89.
Conclusions
The LIBRE Profile-Short Forms demonstrated credible psychometric properties. The short
form version provides a viable alternative to administering the LIBRE Profile when
resources do not allow computer or Internet access. The full item bank, computerized
adaptive test, and short forms are all scored along the same metric, and therefore
scores are comparable regardless of the mode of administration.
