This preliminary clarification warrants further exploring through theoretical and philosophical literature, expert opinions, and empirical research to gain validity and reliability for its application in nursing practice.

The value of Nurse Competence Scale has been confirmed in determining relationships between background variables and competence. The instrument has been widely used with experienced and newly graduated nurses and their managers. Cross-cultural validation must be continued using rigorous methods.

Nurses' Moral Courage Scale provides a new generic instrument intended for measuring nurses' self-assessed moral courage. Recognizing the importance of moral courage as a part of nurses' moral competence and its assessment offers possibilities to develop interventions and educational programs for enhancement of moral courage. Research should focus on further validation measures of Nurses' Moral Courage Scale in international contexts.

Nursing management responsible for and having the power to implement changes should understand their contribution in ethical leadership, as well as the multidimensional nature of nurses' work environment and the interaction between work-related factors in planning developmental measures. Future research should focus on issues in nurse managers' ethical leadership in creating ethical work environments. There is also a need for knowledge of newly graduated nurses' views of factors which act as enhancers or barriers to positive ethical climates to develop. Interventions, continuing education courses, and discussions designed to promote positive ethical climates should be developed for managers, nurses, and multi-professional teams.

Novel perspectives and more diverse methodological approaches paying attentions to issues affecting generalizability of the findings could expand our knowledge in this area.

Management's ability to create and maintain positive practice environments can foster NGNs' professional development and job satisfaction, and consequently retain them in the workforce.

There is a need to develop evidence-based support at the organizational and individual level to support nurses' ethical competence. Barriers for multiprofessional cooperation in ethical issues should be recognized and addressed as part of the development of organizational ethical practices. Research should pay more attention to the conceptual, theoretical and practical perspectives of ethical competence.

Research indicates significant differences between nurse cohorts in many work-related factors. This study compared nurse competence between three generational cohorts comprising the current nursing workforce. The Nurse Competence Scale was used to collect data for this cross-sectional study from 2052 nurses in a university hospital in Finland. Data were analysed statistically. Significant differences were found between nurse cohorts in their competence. The length of work experience had a significant impact on the development of competence. The oldest cohort, with the longest work experience, had the highest competence scores (70.1 on a visual analogue scale), and the youngest had the lowest (59.0). All cohorts were most competent in patient-related nursing tasks, in maintenance of professional competence and in ethical care. Nurses were weakest in the development of nursing practice and the use of evidence-based knowledge. Targeted interventions in teaching-coaching for different nurse generations are needed to ensure the maintenance of nurse competence and high-quality patient care.
