The sense of well-being inventory (SWBI) and the brief adaptation to disability scale-revised (B-ADS-R): Italian translation, cultural adaptation and validation.

STUDY DESIGN: Cross-sectional, psychometric study OBJECTIVE: The Sense of Well-being Inventory (SWBI), Brief Adaptation to Disability Scale-Revised (B-ADS-R) are two of the major assessment tools used for HR-QoL assessment. The study aimed to translate, culturally adapt, and validate the SWBI and the B-ADS-R in Italian.

SETTING: Paraplegic Center of Ostia METHODS: The original scale was translated from English to Italian using international guidelines. The psychometric properties analyzed were: content and construct validity, Internal consistency, and stability. Construct validity was assessed measuring correlation between the assessment tools and Life Space Assessment (LSA), Caregiver Burden Scale (CBS), Manual Wheelchair Slalom Test (MWST), and Adaptation Manual Wheelchair Circuit (AMWC) scales.

RESULTS: The SWBI and the B-ADS-R translated and culturally adapted in Italian were administered to 72 people with Spinal Cord Injury. Both assessment tools resulted in high values of Cronbach's alpha (ranging from 0.72 to 0.95) and intraclass correlation coefficient. With regards to the content validity analysis interests correlations have been found between the B-ADS-R and the physical well-being subscale of the SWBI.

CONCLUSION: The assessment tools analyzed provide rehabilitation professionals, especially those involved in vocational rehabilitation, with assessment measures beyond employment outcomes to improve the definition of success in rehabilitation related HR-QoL. The SWBI and the B-ADS-R help to provide a more valid picture of the individual's level of life satisfaction or HR-QoL.
