    How valid are the psychometric properties of the oral health impact profile-14 measure in adult dental patients in Ibadan, Nigeria?

    BACKGROUND: The Oral Health Impact Profile (OHIP) is the most widely used quality of life (QoL) measure to evaluate the influence of oral diseases on individuals. QoL measures have been noted to be context and environment specific, and there is a need to cross-culturally adapt a scale before its introduction into any community. This study aimed to evaluate the psychometric properties, validity and internal consistency of the OHIP-14 measure in an adult patient population in Ibadan, Nigeria. METHODS: A cross-sectional study was conducted over a four-month period on 204 adult patients using OHIP-14 structured questionnaire, global self-report indicator of oral conditions and perceived treatment need. Oral examinations were performed to assess periodontal status, caries experience and attachment loss. Data were analyzed using SPSS and p-value for statistical significance was set at < 0.05. Results: A total of 204 patients participated in the study with a mean OHIP score of 11.2 (± 9.8). OHIP scores were not related to the sociodemographic characteristics. Perception of need for treatment was greater among those who reported impacts on their QoL (89.3% vs. 14.3%, p < 0.001). The OHIP scores correlated negatively with global self rating of oral health status (rho = -0.23, p < 0.01). Higher OHIP scores were associated with having carious teeth (p = 0.023). The Cronbach’s alpha for the 14 inventory items ranged from 0.857 to 0.871. CONCLUSION: The OHIP-14 measure showed good psychometric properties with satisfactory validity and internal consistency in adult patients in Ibadan, Nigeria

    Validation of the oral impact on daily performance frequency scale in Ibadan, Nigeria
    (2013) Lawal, F. B.; Taiwo, J.O.; Arowojolu, M.O.
    Background: Oral health related quality of life measures provide alternative ways to evaluate oral health status in a way that prioritises impact on lifestyle. These measures are, however, hardly used in our setting. Before the measures can be used effectively, validity of the tool needs to be evaluated. The aim of the study was to validate the Oral Impact on Daily Performance (OIDP) frequency scale in an adult Nigerian patient population. Methodology: This was a descriptive cross sectional study in which consecutive patients attending the Primary Oral Health Care Centre, Idikan and the Oral Diagnosis Clinic of the University College Hospital, Ibadan were recruited. Data was collected with OIDP structured interviewer administered questionnaires, global self-rating and perceived treatment need questions and by oral examination. The frequency scale of the OIDP index was used to compute the impact scores. Data collected was subjected to statistical analysis using SPSS version 19. Results: A total of 204 patients participated in the study. The OIDP score ranged from 0 to 40; 78.9% of the participants reported an impact on daily performance with eating and enjoying food being the most reported activity impacted upon. The Cronbach’s alpha coefficient was 0.811; the OIDP index was significantly associated with global self ratings of oral health, perceived need for dental treatment and was able to discriminate between patients with or without dental caries. Conclusion: The OIDP frequency scale exhibited satisfactory psychometric properties amongst adult dental patients in Ibadan, Nigeria
