To develop a socio-dental impact locus of control scale (SILOC) and to study its relationship with oral health status as well as dental attendance.
Observational cross-sectional study design.
A seven-item SILOC scale based on locus of control and the WHO international classification of diseases’ criteria for “Disability” in relation to oral health was developed. In the pilot study, 100 adolescent school children returned completed forms containing the multidimensional health locus of control (MHLC) and the (SILOC) scale. After confirmation of reliability and validity, 509 adolescent school children returned completed SILOC questionnaires and were examined for caries, plaque and gingivitis. A history of postponement of needed dental treatment was also elicited.
The SILOC scores were highly correlated with the MHLC scores. Factor analysis revealed a two-factor solution accounting for 59 % of the variance. A Cronbach’s alpha of 0.75 showed its internal consistency. Those with higher SILOC scores had greater levels of caries, plaque, gingivitis, and a history of postponing needed dental visits. Multiple logistic regression analysis after adjusting for potential confounders showed that those with high SILOC scores were more likely to have caries (OR = 3.32, p < 0.001), plaque (OR = 1.83, p = 0.026), gingivitis (OR = 1.80, p = 0.012) and a history of ‘Postponement of needed dental treatment’ (OR = 4.5, p < 0.001) as compared with the others.
The SILOC scale showed satisfactory reliability and validity in measuring locus of control orientation in an Indian adolescent population.
