Junior doctors' workplace well-being and the determinants based on ability-motivation-opportunity (AMO) theory: Educational and managerial implications from a three-year longitudinal observation after graduation.

Purpose: Junior doctors function as trainees from an educational perspective and as employees from a human resource management perspective. Employing the ability-motivation-opportunity (AMO) theory as a conceptual framework, this study longitudinally investigated the factors affecting the workplace well-being and career progression of junior doctors over a 3-year period following their graduation from medical schools.

Materials and methods: This 3-year prospective cohort study enrolled junior doctors who graduated from 2 medical schools in June 2019 in Taiwan. This study collected data by implementing web-based, self-administered structured questionnaires at 3-month intervals between September 2019 and July 2022. The collected data encompassed ability indicators (i.e. academic performance and perceived preparedness for clinical practice), motivation indicators (i.e. educational and clinical supervision), opportunity indicators (i.e. clinical unit cultures), and workplace well-being indicators (i.e. burnout, compassion satisfaction, and job performance). A total of 107 junior doctors participated, providing 926 total responses. The data were analysed using univariate analyses and structural equation modelling with path analysis.

Results: Over the 3-year period following graduation, the junior doctors' confidence in their preparedness for clinical practice and the educational and clinical supervision had varying degrees of influence on the junior doctors' workplace well-being. The influence of clinical unit cultures, which can provide opportunities for junior doctors, became evident starting from the second year postgraduation; notably, unit cultures that emphasised flexibility and discretion played positive and critical roles in enhancing the junior doctors' workplace well-being lasted to the third year.

Conclusions: Our findings provide insights into the distinct critical factors that affect the socialisation of junior doctors within workplace environments over 3 consecutive years. These findings can provide guidance for medical educators and healthcare managers, helping them understand and support the progressive integration of junior doctors into their work environments.
