title: Validity and reliability of Oral Impacts on Daily Performances Frequency Scale: a cross-sectional survey among adolescents.
abstract: OBJECTIVE
  To examine reliability and validity of an abbreviated version of Oral Impacts on Daily Performances (OIDP) questionnaire and to analyze the interrelationship among OIDP scores, socio-demographic characteristics and oral health status among 12-15 year old adolescents in Davanagere city, Karnataka, India.
  
  
  METHODS
  The descriptive cross-sectional survey was conducted among 900 adolescents aged between 12-15 years. The study subjects were randomly selected from six high schools. Selected subjects completed a survey instrument designed to measure subjective oral health indicators including the eight-item OIDP frequency scores. The study participants were clinically examined for dental caries and completed a self-administered questionnaire about demographic information and oral behaviors.
  
  
  RESULTS
  44% of the students reported at least one oral impact in the last six months. Cronbach's alpha for the OIDP frequency items was 0.81. Eating was the most common performance affected (33%) followed by cleaning teeth (22%) and speaking (20%). The severity of impacts was low for relaxing and carrying out works.
  
  
  CONCLUSIONS
  The OIDP frequency score have acceptable psychometric properties in the context of an oral health survey among 12-15 year old adolescents.
