Development of an Adult Sensory Processing Scale (ASPS). Article uri icon

abstract

  • This article describes the development of the Adult Sensory Processing Scale (ASPS), a sensory processingquestionnaire for adults. The ASPS measures self-reported responses to input from distinct sensory systemsand is intended to be sensitive to individual differences in the adult population. ASPS construction involvedtwo phases: item development and instrument construction. During item development, content validity of 71items was assessed by means of expert ratings. During instrument construction, items were evaluated usingdata from an online survey of 491 adults. Exploratory factor analysis and Rasch analysis yielded an optimalsolution of eight factors representing vestibular overresponsiveness, auditory overresponsiveness, visualoverresponsiveness, social tactile overresponsiveness, proprioceptive seeking, general underresponsiveness,vestibular–proprioceptive underresponsiveness affecting postural control, and vestibular overresponsiveness–intolerance to movement. The final ASPS contains 39 items and demonstrates acceptable internalconsistency, strong content validity, and adequate construct validity.
