    Oral Health Impact Profile (OHIP-14) and its association with dental treatment needs of adolescents in a rural Nigerian community
    (2016) Lawal, F. B.; Ifesanya, J. U
    To validate and determine the applicability of OHIP-14 in assessing the impact of unmet dental treatment needs on the quality of life of adolescents in a rural community. Methods: The OHIP-14 questionnaire and the Aesthetic component (AC) of Index of Orthodontic Treatment Need (IOTN) were data collection instruments in a cross sectional survey among students in a rural community. The reliability and validity of the OHIP-14 as well as the association between it and dental treatment needs including malocclusion was assessed. Data obtained was analyzed using Mann Whitney U Test. Results: The mean age of participants was 14.9 (±1.6) years. The OHIP-14 had acceptable Cronbach alpha value of 0.8. It could discriminate between respondents with or without dental treatment needs due to caries and dental trauma (p <0.001). The OHIP-14 did not differentiate between respondents with or without orthodontic treatment need (p= 0.808). However, significant association existed between being irritable with people and unmet orthodontic treatment needs (p= 0.032). Conclusion: The OHIP-14 is a valid and reliable quality of life assessment tool in young adolescents in this rural community. However, only the social disability domain component discriminated significantly between those with or without orthodontic treatment needs

    How valid are the psychometric properties of the oral health impact profile-14 measure in adult dental patients in Ibadan, Nigeria?
    (2014) Lawal, F.B.; Taiwo, J. O.; Arowojolu, M. O
    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
