Differences between doctors of medicine and dental medicine in the perception of professionalism on social networking sites: the development of the e-professionalism assessment compatibility index (ePACI).

Background: Social networking sites (SNSs) have penetrated all aspects of health care professionals' (HCPs') professional and private lives. A new term, e-professionalism, has emerged, which describes the linking of traditional values with this new dynamic online environment for HCPs. The four aims of this study were: (1) to examine their SNS prevalence and usage habits, (2) to examine their perception of e-professionalism, (3) to develop an e-professionalism assessment compatibility index and (4) to investigate their tendencies and differences in values of the e-professionalism assessment compatibility index (ePACI).

Methods: A cross-sectional study was conducted among MDs and DMDs in Croatia via email using a questionnaire. The questionnaire was distributed to all MDs and DMDs who were members of their respective chambers. In addition to descriptive statistics, Chi-square or Fisher's exact test when appropriate, t-test, ANOVA and Mann-Whitney U tests were used to determine differences between groups. A principal component analysis (PCA) with varimax rotation was used to investigate dimensionality. Results of the PCA were compared to the coding based on the Social Media e-Professionalism rubric in order to create the ePACI.

Results: Of the 1013 gathered responses, 753 were from valid SNS users and suitable for further analysis. Facebook (91.6%) and Instagram (63.1%) were the predominant SNSs used. Both groups have a good understanding of e-professionalism. The newly developed ePACI deviates slightly in the "conservative" direction in the cases of both, MDs (t = 19.033, p < 0.001) and DMDs (t = 12.991, p < 0.001). HCPs who are older (r = 0.308, p < 0.001), who have fewer SNS profiles (r = -0.142, p < 0.001), and who access their profiles less frequently (r = -0.166, p < 0.001) have statistically significantly more conservative ePACI values.

Conclusions: MDs and DMDs in Croatia are frequent SNS users, with Facebook and Instagram being the main SNSs used. Both groups have a good understanding of e-professionalism. The newly developed ePACI deviates slightly towards the conservative side regarding perception of the e-professionalism content for both groups. The development of the ePACI, and its subsequent usage in further research, will have a direct influence in its validation, gathering comparable data, and be able to direct efforts in oversight, regulation and education.
