This study focused on registered nurses as a promising profession for the future in line with global trends in population aging and an increasing demand for health care services [2, 25, 26]. In recent years, the number of registered nurses in Korea has increased due to the shortage of registered nurses [4]. Unfortunately, the number of students dropping out of the program, such as taking a leave of absence or dropping out, has also increased [6]. Therefore, the current study was conducted to provide basic data in hopes of enhancing nursing students' college adjustment. Specifically, our study examined the relationship between an individual's external (i.e., parental child-rearing attitude) and internal (i.e., ego identity) factors and college adjustment among nursing students.
After examining the relationship between nursing students' perceived parental child-rearing attitude, ego identity, and college adjustment, we found that paternal emotional warmth, maternal emotional warmth, and ego identity were significantly and positively associated with college adjustment (Table 3). The parental child-rearing attitude measurement tool used in this study consists of three subcategories, namely parental emotional warmth, parental rejection, and parental over protection [20]. More specifically, parental emotional warmth included “My parents praised me,” “I think that my parents tried to make my adolescence stimulating, interesting and instructive,” “If things went badly for me, I then felt that my parents tried to comfort and encourage me,” “My parents showed with words and gestures that they liked me,” “I felt that warmth and tenderness existed between me and my parents,” and “I felt that my parents were proud when I succeeded in something I had undertaken.” In other words, parental emotional warmth describes the overall positive parental child-rearing attitudes, such as fondness, pride, praise, comfort, and tenderness [20]. This study found that the external support system of these individuals, especially parental emotional warmth in the closest relationship, enhanced nursing students' ego identity and improved their adjustment to college. Parental support helps college students trust themselves and take responsibility for their actions, which is consistent with previous research showing that parental support and affection enhance ego identity[17, 27]. Affectionate parental child-rearing attitudes have a positive impact on college adjustment and help college students become more accepting, respectful, and confident in themselves [17]. They also help increase the psychological well-being of college students and improve their interpersonal problem-solving skills [28]. In particular, parental emotional warmth (as a subcategory of parental child-rearing attitudes) can provide support and stability for college students in coping with stress and emotional problems while also promoting their inner maturity and development [29]. Based on these previous findings and the results of the current study, we can surmise that parental support and affection have a positive effect on college students' self-identity.
On the other hand, the current study found that nursing students' perceived maternal rejection was negatively associated with self-identity and college adjustment (Table 3). This finding supports previous research showing that parental rejection leads to negative outcomes, such as social anxiety, psychological maladjustment, and smartphone addiction in college students [30–32]. Nursing students' perceived parental rejection leads to anxiety and maladjustment in nursing students and hinders the development of future health care workers [32]. Therefore, universities should establish an organized system to prevent this. For example, universities should engage mothers and provide programs, such as education, counseling, and faculty–parent–student meetings that could improve parenting attitudes. Such programs could provide opportunities for sustaining and enhancing positive parenting attitudes throughout the college years, an early period of self-identification. In addition, these programs can help nursing students adjust to college.
In the current study, nursing students’ ego identity was found to be positively associated with college adjustment. This is consistent with the findings of Kwon [33], who reported that college students' ego identity was positively associated with college adjustment and was a significant factor in explaining college adjustment. College students with a high ego identity tend to have an excellent perception of their own personality and worth, recognize their own competence, and have high self-confidence [33]. Moreover, such students are able to establish a realistic view of themselves and plan for the future based on this view [34]. This disposition has a positive impact on college adjustment [34]. In addition, college students with a high ego identity may have better social and relationship skills given that they are more active in their relationships with others and can resolve interpersonal problems amicably [35]. In short, college students' ego identity can have a positive impact on college adjustment. To this end, universities should provide various programs, such as college life support programs, stress management programs, and mentoring programs, through student counseling centers, learning support centers, and employment support centers to enhance nursing students' adaptation to university [36, 37]. Furthermore, the existing programs in South Korea need to be strengthened and systematically provided to enhance the internal and external factors of college students' ego identity and parental emotional warmth.
As adults, college students become independent of their parents and can psychologically separate their values and beliefs from their parents and make independent choices to live their own lives [38]. Although this process may lead to conflicts with parents, it also allows them to form and strengthen their ego identity [33]. During this time, parents need to respect and support their child's choices to help them develop independence and establish their ego identity, recognize their child's ability to be competent and independent, and provide appropriate support when needed rather than be overly interfering. Parents should have an appropriate child-rearing attitude to help their children establish their ego identity. An appropriate parenting attitude is one that is affectionate, supportive, and trusting of the child, not rejecting or overprotective [31]. Parental roles and appropriate parenting attitudes can be achieved through ongoing education. There have been studies on education and parenting attitudes from infancy to adolescence [39]. However, parenting education for college students who have reached adulthood is very rare in Korea. Therefore, to improve students' adaptation to university, universities should establish programs that not only help students establish their ego identity (an internal factor) but also strengthen their parenting attitude (an external factor) to help them establish their ego identity and adapt to university.
Among general characteristics analyzed herein, only grade level was significantly associated with college adjustment among nursing students. In the current study, third- and fourth-year nursing students had significantly better college adjustment than did second-year students (Table 2). This is consistent with previous research showing that college adjustment increases with grade level [17]. This suggests that as nursing students progress from lower to higher grades, the anxiety, stress, and burden they experienced as freshmen decrease [10], resulting in better college adjustment.
Nursing students who are well-adjusted to college have improved academic skills and academic achievement, as well as better job adjustment [17]. This is an important foundation for providing high-quality nursing care to clients after graduation. Therefore, universities should help nursing students successfully complete their college career academically and personally by preventing and resolving maladjustment issues early in order to generate professional nurses that would contribute to the future of the health care industry. Therefore, universities should be more proactive in helping nursing students adjust to university by developing and implementing ego identity enhancement programs for students and providing parenting seminars for parents.
