Oral impact on daily performance (OIDP) scale for use in Sri Lankan adolescents: a cross sectional modification and validation study

Abstract

Background: Oral Health Related Quality of Life (OHRQoL) measures 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 Sri Lankan adolescents. Methods: Stage I involved cultural adaptation of the tool through translation and modification. Stage II involved the exploring factor structure, validation and a reliability assessment. After translation and cultural adaptation, stage II was conducted among 220 secondary school students aged 15-19 in the Gampaha district, Sri Lanka. Participants completed the modified OIDP scale along with questions on self-reported perceived oral health problems and treatment need which were used to assesses the concurrent validity of the modified OIDP scale. 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: 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 of the modified OIDP scale. 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. The final modified OIDP consists of eight self-reported items which assesses the impact severity of eight daily performances over past three months. Participant scores ranged from 0 to 24 out of a worst possible score of 40, and nearly 48% of the responders reported at least one impact during past three months. The most prevalent oral health impact related to chewing and enjoying foods, reported by 36.8% of respondents. Conclusion: This study suggests that the modified OIDP scale has promising psychometric properties and is appropriate for use among adolescents in Sri Lanka. Further research is required to test the validity of this tool in other cohorts.

The Influence of Periodontal Disease on Oral Health Quality of Life in Patients with Cardiovascular Disease: A Cross-Sectional Observational Single-Center Study

“…There are several oral-health quality-of-life instruments such as GOHAI (Geriatric Oral Health Assessment Index) [ 61 ] used for elderly patients and OIDP (oral impacts on daily performances) for adult and adolescent use [ 62 ]. The most frequently applied tests are OHIP with its shorter version OHIP-14, with an easy and quick application.…”

Key factors associated with oral health-related quality of life in Sri Lankan adolescents: a cross sectional study

“…The OIDP index was initially developed by Adulyanon [ 6 ] and later modified and validated in a sample of 220 Sri Lankan adolescents aged 15–19 [ 8 ]. During cross-cultural adaptation of the questionnaire, some items were modified and the scoring system was revised to report only the severity of the impact with a recall period of three months.…”

“…A number of questionnaires are available to measure socio dental indicators in a population, including the Oral Impact on Daily Performance (OIDP) tool [ 6 ]. The OIDP is conceptually based on the International Classification of Impairments, Disabilities and Handicaps created by WHO in 1980 [ 7 ], and validated on a group of Sri Lankan Adolescents [ 8 ]. The association between sociodemographic and socioeconomic factors, clinical dental conditions and OHRQoL indicators has been investigated in adolescent populations across the world.…”

The complexity of dental anxiety and its association with oral health‐related quality of life: An exploratory study

“…This three‐factor structure has since been validated in several studies [ 35 , 36 , 37 ]. However, several studies have also found both one‐factor and two‐factor structure solutions [ 38 , 39 ]. The OIDP scale consists of eight items and is measured using a five‐point Likert‐type scale (1 = every day or almost every day, 2 = once or twice a week, 3 = once or twice a month, 4 = less than once a month, and 5 = never), with a minimum sum score of 8 and a maximum sum score of 40.…”
