Personality differences in dental professionals: A cross-sectional survey

Abstract

Despite its influence on occupational performance and team dynamics, there has been little research into the personality of dental professionals. Existing research does not typically use the prevailing five-factor model of personality. We aimed to measure the personality of dental professionals in the United Kingdom and investigate differences among groups. The sample (n= 906) comprised dental nurses (n= 475), general dental practitioners (GDPs) (n= 182), orthodontists (n= 201), and oral and maxillofacial surgeons (OMFSs) (n= 48). Recruitment was via email and social media. The questionnaire collected data on demographic variables and contained the Big Five Inventory, a validated self-report personality test. Participants scored on extraversion, conscientiousness, agreeableness neuroticism, and openness. A one-way analysis of variance and post-hoc tests with Bonferroni correction were used to identify significant differences in personality between occupations. Hierarchical multiple regression determined the influence of occupation over and above demographic variables. On a 5-point scale, orthodontists had a mean conscientiousness score 0.23 points higher than GDPs (95% confidence interval [CI], 0.10-0.36). Dental nurses had a mean conscientiousness score 0.28 points higher than GDPs (95% CI, 0.17-0.39). Dental nurses had a mean agreeableness score 0.16 points higher than orthodontists (95% CI, 0.05-0.27) and 0.30 points higher than OMFSs (95% CI, 0.10-0.50). For neuroticism, orthodontists had a mean score 0.21 points lower than dental nurses (95% CI, 0.06-0.36), and OMFSs had a mean score 0.43 points lower than dental nurses (95% CI, 0.16-0.70). GDPs had a mean neuroticism score 0.43 points higher than OMFSs (95% CI, 0.14-0.71; P=0.001). Differences were small to moderate in size (d= 0.35-0.45) and occupation was associated with personality after accounting for demographic variables. The personalities of dental nurses, GDPs, orthodontists, and OMFSs differed. Occupation was associated with differences in personality after accounting for demographic characteristics.
