This study used a nonexperimental quantitative design with a cross-sectional approach. A self-report questionnaire was delivered by e-form at one point in time.

The population was new nurses at 2 hospitals with less than 1 year of service. Total sampling was used for this study. We selected these 2 hospitals because they are in the same city and have both implemented preceptorship programs. Total sampling was used to reach a larger number of respondents because the number of new nurses at one time in one hospital was not large enough. To reduce bias, we used enumerators to collect data.

Respondent inclusion criteria were new nurses who have worked for less than 1 year at hospitals. Respondents were undergoing an orientation period and preceptorship program. Respondents were only excluded if they were unwilling or absent when the data were collected.

Respondents involved in this study were nurses from 2 hospitals. Hospital X had 107 nurses who participated and Hospital Y had 62 nurses.

The instrument is separated into 7 parts, namely respondent characteristics, self-efficacy [17], adaptation of new nurses, preceptorship methods [18], preceptor commitment [19], preceptor competence [20], and new nurses’ competency [21]. This instrument for new nurses’ competency was developed by the research team because we could not find a suitable instrument for new nurse competencies according to the standards in Indonesia. This instrument consists of 36 questions and has a validity value above the calculated r value, greater than the table r value (0.3). Meanwhile, Cronbach α was .989. We conducted a reliability test for new nurse self-efficacy (r=.934), new nurse adaptation (r=.878), preceptor competence (r=.996), preceptorship method (r=.948), and preceptor commitment (r=.807). The validity test is considered valid if the value of r count is greater than the table value of r (.361); therefore, all items were declared valid [22].

This research received ethical clearance from the Research Ethics Committee of the National Cardiovascular Center Harapan Kita Jakarta (letter number LB.02.01A/II/039/KEP039/2023).

In this study, 169 new nurses participated, with a median age of 24 years. The youngest nurse was 22, while the oldest was 30. Most of the participants were female (n=136, 80.5%), had a bachelor’s degree (n=164, 97%), and had worked at a hospital for 0‐6 months (n=128, 75.7%). The nurses and midwives already had Basic Cardiac Life Support training (n=142, 84%; Table 1).

Table 2 shows that the adaptation of new nurses and mentoring method had a lower median (both 2.9) than other variables (3.0), although the lowest minimum value was for preceptor commitment (1.5).

Researchers used the median value as a cutoff for determining whether each component was considered positive (more than the median score) or negative (less than the median score).

As shown in Table 3, we found that the variables that were significantly related to the new nurse competencies were self-efficacy (P=.001), adaptation of new nurses (P=.001), mentoring methods (P=.001), preceptor commitment (P=.001), preceptor competence (P=.001), gender (P=.02), and training (P=.05).

As displayed in Table 4, we found in the final model that the independent variables (mentoring methods, preceptor commitment, and preceptor competence, gender, and training) simultaneously had a significant effect on the competence of new nurses (there must be at least 1 independent variable that influences the dependent variable, significant if α<.05).

This study found that mentoring methods, preceptor commitment, preceptor competency, gender, and training were factors that influenced new nurses’ competency. A previous study stated that nurse mentors who have expertise and use a supportive approach can promote a healthy work environment [23]. Another study found 7 core competencies of nurse preceptors: teaching traits, clinical nursing profession, communication and collaboration, teaching pedagogy, reaction of contingency, critical thinking and reflection, and consultation on academic writing [24]. Previous research found that transition shock and perceptions of supervisors were significantly correlated with new nurses’ competency [25,26].

New nurses are expected to be able to adapt to the clinical environment, interact effectively, build strong partnerships with other professionals, and be able to make correct clinical decisions [27]. The mentor must be competent and have strong personal character traits and be able to think critically [28].

An important role of preceptors in the preceptorship program is to build new nurse competencies. A previous study stated that new nurses did not feel confident in performing many procedures independently without support from their supervisor (a manager, registered nurse, or mentor) [29].

In this study, the perception of new nurses regarding mentoring methods was still lacking (44.2% of new nurses gave a positive response to the mentoring method item). This was due to the lack of guidance in the orientation, classroom learning, mentoring, and evaluation phases. Another study found that updated guidance methods, including the application of evidence-based practice, can stimulate students to learn more about the cases they handle. This method can increase student knowledge [30]. In our study, the majority of preceptors had implemented the preceptorship method well, although there were still 18% who were not good [31].

The results of the statistical analysis showed that preceptor commitment had an effect on new nurse competencies. Another study found that there are low levels of role commitment among new mentors in Taiwan [32,33]. However, they act as good guides because this is an opportunity to teach, improve their teaching skills, share their knowledge, gain personal satisfaction, help new nurses and nursing students to integrate into the unit, and enhance their professional knowledge. A preceptor’s commitment to their role is associated with obtaining the benefits, appreciation, and support associated with this role. According to preceptors, to optimize the effectiveness of the nurse preceptorship program, it is necessary to understand that benefits, rewards, recognition, and support for preceptees must be an integral part of planning these programs [19].

An effective preceptorship program requires preceptors who have specific professional factors and personal characteristics. A clear evaluation process was planned from the start, incorporating feedback from preceptors and preceptees to make further improvements to the preceptorship program in the future. There is no standardization of preceptor competency; therefore, basic national competency standards for becoming a preceptor must be developed.

A limitation of this study is that the new nurse competency instrument was created by the researchers. This instrument is not yet standardized.

Mentoring methods, preceptor commitment, preceptor competency, gender, and training were factors that influenced new nurses’ competency. Results from this research could be considered by hospitals’ nursing divisions when determining strategies to increase the competency of new nurses. Preceptorship programs are an important part of this strategy, where preceptor competence, preceptor commitment, and mentoring methods are a priority. New nurses must receive proper training to improve their competency before they enter the workforce.
