Abstract
The objective of this study was to illustrate the relationship between optimism and defense me-
chanism in Korean college students. 332 student participants from “A” University in Korea com-
pleted questionnaires from the Ewah defense mechanism and optimism measurement tool. This
study analyzed the culled data and revealed general patterns of optimism and defense mechanism,
as well as patterns based on gender. In addition, the study analyzed differences in defen se me-
chanism, dictated by one’s optimism level. Frequency, percentage, mean, standard deviation, and
t-test were analyzed using SPSS 21.0. The results demonstrated that the operating defense me-
chanism in Korean college students were different for males and females in the categories of
show-off, passive aggressive, denial, and identification. However, the level of optimism was iden-
tical for both genders. Defensive mechanisms based on optimism levels also varied significantly in
controlling, distortion, altruism, humor, sublimation, and rationalization categories.

1. Introduction
College years are typically considered as the period between post adolescence and early adulthood where inde-
pendent search for ego-identity and development into a more mature ego take place. However, college students
in Korea tend to depend on their parents much longer compared to their counterparts in Western societies. Con-
sequently, although they have reached a certain age and physiological development, they lack independence and
maturity in the areas of the social, psychological, and financial. In other words, college students in Korea are ill
prepared to embrace this new environment in which they must suddenly make decisions on their own. The Ko-
rean education system, which overemphasizes the college entrance exam throughout the middle and high school
years, is the primary cause for this social phenomenon. Korean students acquire an education solely based on
standardized exams, developing a passive attitude for learning. Given this predicament, the researchers had to
pay attention to the concept of optimism, a Positive Psychology personality trait which helps to foster healthy
development and adaptation. Optimism is a positive anticipation about future events that act as an important

factor to help reduce maladaptive problems such as distress and interpersonal issues. The previous studies have
discovered that optimistic college students received more social support, and scored higher in life satisfaction
and academic achievement, and experienced fewer psychological challenges, including stress, depression, and
loneliness. In addition, there was a positive correlation between optimism and psychological well-being [1].
On the other hand, defense mechanism refers to thoughts, emotions, attitudes, and behaviors that one uses in
order to resolve conflicts that work at both the preconscious and unconscious levels of the mind [2]. Defense
mechanism is a critical factor in identifying neurosis [3]. Similar to a personality trait, d efense mechanism ap-
pears as a fixation in adulthood [4]; therefore, it is considered an important concept in understanding human be-
havior [5]. If d efense mechanism patterns can be evaluated objectively, they can manifest an individual’s adap-
tation patterns and personality types [6] and in-group memberscharacteristics, behavioral patterns, and adapta-
tion mechanisms [7] [8].
This study set out to investigate characteristics and behavioral patterns of Korean college students based on
their defense mechanism, and to determine whether an important correlation between optimism and defense
mechanism exists. The research pursued the following questions:
1. How do optimism and defense mechanism vary by gender?
2. What are the differences in defense mechanism based on optimism?
2. Method
A. Participants
As shown in Table 1, 332 students52 male and 280 femalefrom “A” University in Korea were selected
to participate in this research.
B. Research Tool
1. Optimism test
The researchers of this study used Carver and Bridges Life Orientation Test-Revised (1994), adapted by Shin
(2005) [9] to measure optimism. A total of 10 questions, of which numbers 1, 4, and 10 inquired about general
positive expectations, and numbers 3, 7, and 9 predicted pessimism, were asked. The remaining 4 questions
were designed to distract the participants so that they could not figure out the purpose of the study. The 5-point
Likert Scale was used, and the scores ranged from 6 to 30, the higher scores denoting higher levels of optimism.
The original measuring tool [10] had a reliability of 0.78, and Shin Hyun-Suks adapted version (2005) [9] indi-
cated 0.65 in optimism questions, and 0.60 in pessimism questions. A current study by Lee (2010) [11] proved
0.80 reliability, while this study demonstrated 0.75 in Cronbach’s
α
.
2. EDMT: Ewah Defense Mechanism Test
This study used the Ewha Defense Mechanism Test [2] in order to measure defense mechanism. The process
of scoring tests and analyzing results also followed EDMT guidelines. The reliability of this test has been
proved to be 0.66 ~ 0.88 in split-half method, the test-retest method after 2 weeks which showed 0.72 reliability.
The test was designed to examine adaptation and defense mechanism in Korean-specific context. The test con-
sisted of 20 defense mechanism measurements, and every scale included 10 questions, for a grand total of 200
questions. The 5-point Likert Scale was used to calculate the scores, and the aggregate from all 10 questions
made up the raw score. The revised score was applied afterward.
3. Data Analysis
Frequency, percentage, mean, standard deviation, and t-test were determined using SPSS 21.0 for data analy-
sis.

Table 2 demonstrates that optimism scored a bit higher than average (M = 3.17, SD = 0.35).
Table 3 displays the defense mechanism and its subordinate categories. Regression, reaction formation traits,
and identification were the top three, while the least used defense mechanism were distortion, denial, and act-
ing-out. Overall, regression was the most distinctive element while distortion was barely present.
2. Differences in optimism by gender
As Table 4 shows, there was difference in optimism based on gender.
3. Gender differences in defense mechanism
Table 5 displays significant differences in defense mechanism between male and female students. Male stu-
dents applied more passive aggressive, denial, and rationalization, while female students relied on more identi-
fication and regression.
4. Defense mechanism based on optimism
In order to determine the differences of defense mechanism based on the level of optimism, the researchers
divided the data into 2 different groups. 30% of the participants who scored the highest in defense mechanism
were selected to be the first group, and lowest 30% were placed in the second group. Table 6 illustrates the t-test
results: Lower optimism group displayed controlling, distortion, humor, and rationalization. And higher optim-
ism group displayed altruism and sublimation. However, there was no significant difference in ego negative
pattern of defense mechanism in terms of optimism level.

4. Discussion
The goal of this study was to demonstrate a relationship between optimism and defense mechanism in Korean
college students, and the results revealed following.
First, Korean college students scored higher than average in optimism, and the women scored lower than men
in optimism. Based on the Self-Control Behavior Model of Optimism, those with greater optimism exhibit super-
ior skills in dealing with stressful situations, positive outlook, and possessing an optimistic view of reality. They
are also confident in managing a variety of daily challenges effectively [15].
This study shows that Korean college students appear to be relatively positive. That female students scored
lower in optimism is an indication that they lag behind their male counterparts in terms of coping skills, outlook,
and perspective of reality.

Defense mechanisms that Korean college students rely on most frequently are showing off, passive-aggres-
sive, denial, and identification, in this order. This supports Kim Doo-Han’s study (2004), which concluded that
engineering students use denial within the Behavior Inhibition category and art students use showing off [2] [14].
Among the main categories of defense mechanism, the male students display unstable sensitivity, such as
passive-aggressive and behavior inhibition, like denial or rationalization. The female students, on the other hand,
rely on identification and regression. This shows that men depend more on the behavior inhibition mechanism,
while female students opt for the passive defense mechanism. Hence the women are slightly less mature or in-
dependent [2] [12].
Second, the researchers divided the data into 2 groups based on average optimism—the top and bottom 30%
of participants—and analyzed the results.
The high group utilized all the ego exploration sub-categories: control, distortion, and humor. They also
leaned on behavior inhibition, such as rationalization.
In addition, the top optimism group often used mature defense mechanisms, such as altruism and sublimation
[13]. These results are in line with Kim Sang-In’s study which determined that people with high optimism use
mature defense mechanisms. Consequently, they are emotionally happier and psychologically healthier than
those who rely on less mature defense mechanisms [16].
The limitation of this study: the researchers used collected data only from college students from “A” univer-
sity in Korea. Therefore, applying these results to the general population might not be reliable.
