Aim:
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.
Method:
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.
Conclusion:
The OIDP frequency score have acceptable psychometric properties in the context of an oral health survey among 12-15 year old adolescents.
