Factors associated with orthodontic patient compliance with intraoral elastic and headgear wear

Abstract

Factors related to compliance with the wearing of headgear and intraoral elastics were explored in a sample of 100 university clinic orthodontic patients. Data were gathered by means of a questionnaire that comprised items presumed to be associated with orthodontic compliance. These items were not patient characteristics, but variables of beliefs, attitudes, perceptions, and reasons thought to be associated with compliance. The 58 questions were reduced through alpha factor analysis and the imposition of a coefficient alpha restriction to 12 factors. These 12 factors were named according to the questions they comprised. To assess whether these factors were indeed related to compliance, correlation coefficients were calculated between the factor scores (independent variables) and the criterion of compliance with headgear and elastics (dependent variable). Compliance was rated on a three-point scale. Four factors were found to be weakly, though significantly, correlated with compliance. These factors were combinations of personality type, negative motives (pain, inconvenience, and dysfunction), and positive motives (general health awareness, specific dental knowledge, and personal oral embarrassment). The findings were compared with existing theories of patient behavior.
