Reliability and convergent and discriminant validity of the Child Oral Health Impact Profile (COHIP Child's version).
The purpose of the current study was to assess the reliability as well as the convergent and discriminant validity of the Child Oral Health Impact Profile (COHIP). The questionnaire consisted of five domains that assessed oral health, functional well-being, social-emotional well-being, school environment, and self-image. COHIP was designed to measure self-reported oral health-related quality of life (OHRQoL) of children between ages 8 and 15 years old, using both positively and negatively worded items. ⋯ The overall COHIP showed excellent scale reliability overall and test-retest reliability. Both discriminant and convergent validity of the COHIP were supported by the comparisons among and within the four groups of children. Further testing will examine the utility of the instrument in both clinical and epidemiological samples.
