Test–Retest Reliability of the Sensory Profile Caregiver Questionnaire

Abstract

OBJECTIVE: We examined the test-retest reliability and internal consistency of the Sensory Profile Caregiver Questionnaire (SP). METHOD: Fifty-five primary caregivers of children 36-72 mo old participated in the study. Participants completed the SP on two separate occasions 7-14 days apart. Participant data were analyzed using intraclass correlation coefficients (ICCs) and Cronbach's α coefficients. RESULTS: Test-retest reliability was good across quadrant scores (ICC([2, 1]) = .80-.90) and moderate to good across factor (ICC([2, 1]) = .69-.88) and section scores (ICC([2, 1]) = .50-.87). Internal consistency was high across quadrant (αs = .89-.95) and factor scores (αs = .82-.93) and moderate to high across section scores (αs = .67-.93). CONCLUSION: This study suggests the SP has acceptable test-retest reliability and internal consistency and supports the use of quadrant scores over factor and section scores to analyze children's sensory processing patterns.
