    Author: Jang Y, Hsieh CL, Wang YH, Wu YH.
    Journal: Arch Phys Med Rehabil; 2004 Nov; 85(11):1890-5. PubMed ID: 15520987.
    Abstract:
    OBJECTIVE: To examine the distribution of the scores, internal consistency, structure, and discriminant validity of the abbreviated version of the World Health Organization Quality of Life (WHOQOL-BREF) assessment in persons with traumatic spinal cord injury (SCI). DESIGN: Validation study using multitrait analysis and known-groups methods. SETTING: Community and hospital. PARTICIPANTS: Persons with SCI (N=111) and non-SCI respondents (N=169). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: The WHOQOL-BREF assessment. RESULTS: The frequency distribution of the 4 domains of the WHOQOL-BREF assessment was nearly symmetric and showed no floor or ceiling effects. All domains showed good internal consistency (Cronbach alpha range, .74-.78), with the exception of the social relationships domain (alpha=.54). The 4-domain structure of the WHOQOL-BREF assessment was confirmed using multitrait analysis. The discriminant validity of the WHOQOL-BREF assessment in persons with SCI was satisfactory. CONCLUSIONS: The WHOQOL-BREF assessment is suitable for measuring QOL as perceived by a person with SCI.
