Sammanfattning

Objective To evaluate the psychometric properties of the Swedish version of the Glasgow Benefit Inventory (GBI). Methods A prospective multicenter cohort study was conducted. A total of 123 otosclerosis subjects were included in the study. The subjects were divided in three groups based on the following interventions: (a) stapedotomy without any prior hearing-aid rehabilitation (n = 60); (b) hearing-aid rehabilitation without any prior stapedotomy (n = 33); and (c) stapedotomy with prior hearing-aid rehabilitation (n = 30). Pre- and post-operative pure tone audiometry were measured. The Swedish version of the GBI was completed by the subjects 6 months after the intervention. Test-retest reliability and internal consistency, factor analysis, construct validity, and criterion validity, was assessed. Results The Swedish version of the GBI was well accepted by the subjects. It showed good psychometric properties with an overall high reliability. Factor analysis resulted in a 5-factor solution explaining 66.6% of the variance where factors 1 and 2 represented the general health domain. Conclusions Overall, the Swedish version of the GBI showed good psychometric properties. Based on the factor analyses, there is the possibility that the general health domain should be divided in two separate domains: general health and psychosocial health. Level of Evidence 2c.
