The Dutch Sensory Gating Inventory (D-SGI)

The Sensory Gating Inventory (SGI) is an established self-report questionnaire that is used to assess the capacity to filter redundant or irrelevant environmental stimuli. Translation and cross-cultural validation of the SGI are necessary to make this tool available for Dutch speaking environments. This study therefore aimed to (1) design a Dutch Sensory Gating Inventory (i.e., D-SGI) and to (2) validate the D-SGI. A forward-backward translation was performed and 469 native Dutch speakers filled in the questionnaire. A confirmatory factor analysis assessed the psychometric properties the D-SGI and to measure test re-test reliability. Results confirmed satisfactory similarity of psychometric properties for the factor structure of the D-SGI to the original English SGI. Similarly, the internal consistency and discriminant validity were ratified. Test-retest reliability also indicated good results. These findings confirm that despite some noteworthy differences, the D-SGI is a psychometrically sound self-report measure to assess sensory gating in the Dutch population.
