Oral Impact on Daily Performance (OIDP) scale for use in Sri Lankan Adolescents: Modification and validation of a Sinhalese version [post]

2019 unpublished
Oral Health Related Quality of Life (OHRQoL) surveys play an important role in understanding subjective patient experiences in oral health care. The Oral Impact on Daily Performance (OIDP) scale is a validated OHRQoL tool that measures the impact and extent to which an individual's daily activities may be compromised by their oral health. It is commonly used to facilitate oral health service planning. The aim of this study was to modify and validate a Sinhalese version of the OIDP for use in

After translation and cultural adaptation, the modified OIDP was tested on 220, 15-19 year old adolescents in Sri Lanka. The adolescents completed the modified OIDP scale together with the questions evaluation their self-rated oral health as a selfadministered questionnaire. This involved the exploring factor structure, validation and a reliability assessment. Factorability was assessed by inspection of correlation matrix and Kaiser-Meyer-Olkin and Bartlett's Test of Sphericity tests as a measure of sampling adequacy. An exploratory factor analysis was carried out using Principal Component Analysis method and factors were rotated using the oblimin method. Results 220 adolescents participated in factor analysis and validation studies. The Kaiser-Meyer-Olkin measure was 0.87 and Bartlett's test of Sphericity was significant (p<0.001) Cronbach's alpha was calculated as 0.88, indicating a high level of internal consistency. The principal component analysis produced two factors with Eigen values ranging from 1.12 to 4.40, explaining 70.0% of total variance. Concurrent validity was satisfactory as the OIDP score increased when the adolescents' perceived oral health decreased. Conclusion This study showed that the modified OIDP scale is applicable for use among adolescents in Sri Lanka. It has promising psychometric properties but further research is required to use this tool in other cohorts.
