Reliability and Validity of the Korean Child Sensory Profile-2

The Korean Child Sensory Profile-2 (K-CSP-2) is a tool for assessing sensory processing that was recently culturally adapted for use with Korean children.

To investigate the test-retest and interrater reliability and the convergent and discriminant validity of the K-CSP-2.

Cross-sectional study.

Community settings in South Korea.

Caregivers of 102 children with autism spectrum disorder (ASD) and 156 typically developing (TD) children ages 3-14 yr.

The K-CSP-2 was tested for reliability and validity using the Korean version of the Sensory Profile (K-SP) and the Korean Behavior Assessment System for Children-2 (K-BASC-2).

The K-CSP-2 demonstrated good test-retest and interrater reliability. The K-CSP-2 was correlated with the K-SP and the K-BASC-2. Children with ASD had higher K-CSP-2 scores than TD children. The discriminant analysis classified children with ASD and TD children with an overall accuracy of 89%.

The K-CSP-2 can be used to assess the sensory processing of Korean children consistently across time and raters. The instrument maintains the quadrant factors of the K-SP and relates to adaptive and maladaptive behaviors. The K-CSP-2 can distinguish children with ASD from TD children. What This Article Adds: Korean occupational therapy practitioners can use the K-CSP-2 to identify sensory processing patterns and to support the evaluation of children with ASD.
