title: Validation of a Korean version of the Child Oral Health Impact Profile (COHIP) among 8- to 15-year-old school children.
abstract: OBJECTIVE
  The purpose of this study was to assess reliability, discriminant validity, and convergent validity of the Oral Health Impact Profile (COHIP) Korean version in a representative community sample of 8- to 15-year-old Korean children.
  
  
  METHODS
  A Korean version of COHIP was developed according to the standard procedure of cross-cultural adaptation of self-reported instruments. A representative community sample of 2236 schoolchildren was selected by cluster sampling method.
  
  
  RESULTS
  Mean age of the participants was 11.8 years. Mean and median of the overall COHIP score were 103.3 (SD 13.3) and 106, respectively. Internal reliability and retest reliability were excellent with Chronbach's alpha 0.88 and intraclass correlation coefficient 0.88. Face validity was confirmed with 98% of participants reporting the COHIP questionnaire was easy to answer. Nonclinical factors such as self-rated oral health or satisfaction with oral health were significantly related with overall COHIP score and five subscale scores (P < 0.001) in a consistent manner. Children with carious permanent teeth and with orthodontic treatment need had highly significantly lower overall COHIP score (P < 0.01).
  
  
  CONCLUSIONS
  The Korean version of the COHIP was successfully developed. The internal reliability, retest reliability, face validity, discriminant validity, and convergent validity of the COHIP Korean version were confirmed.
