Abstract
PURPOSE: A common and frequent consequence of an acquired brain injury (ABI) is the diminished quality of life (QoL) of affected people. Because the majority of existing QoL instruments assess health-related domains, new instruments that allow for the evaluation of the QoL from an integral perspective that considers the context and personal factors of the individual are warranted. Hence, the purpose of this study is to develop and validate an instrument with these characteristics. METHODS: The CAVIDACE scale is a new 64-item specific instrument to assess QoL in people with ABI based on a third-person perspective. The validation sample comprises 421 adults with ABI, with ages ranging from 17 to 90 years (M = 53.12; SD = 14.87). The scale was completed by 97 professionals and 58 family members. Validity evidence based on the internal structure of the scale was provided through confirmatory factor analyses. Reliability was analyzed in terms of internal consistency and inter-rater reliability. RESULTS: The results supported the internal structure of the scale, based on the theoretical and assessment framework in which QoL is composed of eight intercorrelated first-order domains (CFI = 0.890, RMSEA = 0.065, SRMR = 0.071). The internal consistency was good or excellent for the eight domains (ordinal alpha ranging from 0.77 to 0.93). The inter-rater reliability was very high (0.97). CONCLUSIONS: The CAVIDACE scale is found to be a specific instrument with excellent psychometric properties that is helpful for the assessment of QoL in people with ABI, both in clinical practice and for research purposes.
