An overview & critical review of the Sensory Profile – second edition

Abstract

Background The Sensory Profile-2 (SP-2) is the recently revised set of scales that provide information about a child’s responses to different types of sensory stimuli. Aim To examine the methodological quality and psychometric properties of the SP-2 using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) and Quality Criteria for Health Status Questionnaires (QCHSQ). Materials and Methods The methodological quality and psychometric properties for each of the SP-2 scales were examined by two assessors using the COSMIN and QCHSQ. Results The COSMIN revealed that the SP-2 demonstrated strengths in patient-related outcome measure design and internal consistency. However, hypothesis testing, cross-cultural validity and structural validity (construct validity) were notable shortcomings. The QCHSQ indicated the SP-2 has merits in its content validity and construct validity. The SP-2 manual reported insufficient evidence of its responsiveness, interpretability and criterion validity. Conclusion Informed assessment selection is fundamental for evidence-based and quality occupational therapy practice provision. Overall, the SP-2 is considered to have adequate psychometric properties, however users should be mindful of the identified shortcomings. Significance The review and critique of the SP-2 adds to the body of knowledge about the revised instrument and provides an objective perspective about its strengths and weaknesses.
