The Effect of Core Job Characteristics on the PROTECTION of Medical Skincare Workers on the Organizational Effectiveness: With a Focus on the Mediating Effect of Self-Efficacy

Purpose: This study sought to examine the effect of core job characteristics, which is a concept related to the protection of medical skincare workers, on the organizational effectiveness with a focus on the mediating effect of self-efficacy. The aim is to help facilitate the development of the beauty service industry by promoting the achievement of organizational goals by securing professional manpower with job performance skills and by elevating the quality of the customer satisfaction services. Method: In this study, 405 copies of the online questionnaires for the medical skincare workers serving at skincare rooms and plastic surgery clinics by utilizing the IBM SPSS Statistics 25 program. To validate the effect of the core job characteristics of medical skincare workers on the organizational effectiveness by mediating self-efficacy, a 3 phased hierarchical multiple regression analysis was performed following the validation procedures of the mediating effect proposed by Baron & Kenny(1986) and the Sobel test was conducted to validate the mediating effect. Results: As a result of carrying out a 3 phased hierarchical multiple regression analysis in this study, in the first phase, among the sub-factors of the core job characteristics, which are the independent variables, job importance, feedback, job diversity, and autonomy, excluding job identity, were found to have sequentially impacted positively on the parameter of self-efficacy. In the second phase, among the sub-factors of the core job characteristics, which are the independent variables, autonomy, feedback, and job importance were found to have sequentially impacted positively on the dependent variable of organizational effectiveness. Lastly, the parameter self-efficacy and the independent variables of autonomy and feedback were found to have a positive effect on the organizational effectiveness. In the result of the Sobel test additionally conducted to validate the mediating effect, it was found that self-efficacy plays a mediating role in the relationship where job importance and feedback are impacting the organizational effectiveness. Conclusion: Based on the result of this study, it was validated that the job importance and feedback of the medical skincare workers increase the self-efficacy, and the increased self-efficacy in turn increases the organizational effectiveness. Hence, if self-efficacy is increased by providing feedback through education and a systematic inspection of their job with supervisors and colleagues for the perception of the importance of job for the members of organization, it will not only bring a positive effect on the performance of the organization, but also protect the employees, thereby promoting the achievement of organizational goals via efficient manpower management.
