OBJECTIVE: In Korea, online board games, such as “flower cards,” are played using virtual money. In contrast, Internet-based gambling (ibGambling) concerns the use of real money to gamble online. We hypothesized that online board gamers using virtual money show less risky behaviors than do gamblers who use real money, and that, in regard to psychological aspects, online board gamers are less depressed and more introverted than online gamblers are. METHODS: For this study, 100 online board gamers, 100 ibGamblers, 100 offline gamblers (offGamblers), and 100 age- and sex-matched healthy controls were recruited by an online research company. Gambling behavior and self-efficacy were assessed using the Korean Gambling Behavior Scale-high/low factors (KGBS-H/L) and the Gambling Abstinence Self-efficacy Scale (GASS). Additionally, introversion, depression, and mania tendency were assessed. RESULTS: Online board gamers had good intentions gaming, as evidenced by their higher KGBS-L scores than ibGamblers and offGamblers, and they showed less risky behaviors, as evidenced by their lower KGBS-H scores than offGamblers. Additionally, online board gamers were less introverted than ibGamblers and less depressed than offGamblers. CONCLUSION: Online board gaming could be a gateway to the world of gambling (ibGambling or OffGambling). However, the higher tendency of online board gamers to engage in good intentioned gaming could help prevent online board gaming from progressing to online or offline gambling.

OBJECTIVES: The purpose of this study was to test the construct validity of the Type D personality scale (DS14). METHODS: The DS14 and other personality scales, which have good construct validity (MMPI-2), TCI-RS, MBTI, NEO-PI-R) were administered to 151 college students. Correlation and regression analyses were performed to evaluate the validity of the DS14. RESULTS: There were significant positive correlations between the DS14 total score and scores on the F, D, Pa, Pt, Sc, Si and 'negative emotionality' scales (MMPI-2), the 'harm avoidance' scale (TCI), the 'neuroticism' scale (NEO-PI-R), and the 'introversion' scale (MBIT). Additionally, there were significant negative correlations between the DS14 total score and extroversion, agreeableness, openness to experience, cooperativeness, and reward dependence scales. Stepwise regression analysis also showed coherent RESULTS: negative emotionality, introversion, RCd and RC2 (MMPI-2), harm avoidance (TCI), neuroticism (NEO-PI-R), introversion, thinking (MBIT) scales were selected as significant explanatory variables. CONCLUSION: Individuals with a Type-D personality, as assessed by the DS14, seem to have a tendency to experience negative emotions such as depression and anxiety. As a construct, Type-D personality also seems to be closely related to neuroticism and introversion. These results indicate that the DS14 has sound construct validity as a screening tool for measuring stress-vulnerability traits, that is to say, type-D personality.

PURPOSE: Current study was designed to understand the personality and emotional composition of patients with chronic constipation. Specifically, the personality differences were evaluated in the ramified subgroups based on the physiologic characteristics. METHODS: Forty patients (31 females and 9 males) of a mean age of 48 (range, 16~86) years underwent the MMPI among 310 patients with chronic constipation. MMPI (Minnesota Multiphasic Personality Inventory) profiles were utilized for psychologic assessment for all patients prior to making diagnosis. Three validity scales of MMPI included L (Lie scale), F (Infrequency scale), K (Suppressor scale). Ten clinical scales included HS (hypochondriasis), DP (depression), HY (hysteria), PD (psychopathic deviant), MF (masculinity- feminity), PA (paranoia), PT (psychasthenia), SC (schizophrenia), MA (mania), SI (social introversion). On the basis of findings with use of anorectal physiologic studies, subgroups were categorized as patients with rectocele (A1, n=22), patient without rectocele (A2, n=18), patients with nonrelaxing puborectalis syndrome (B1, n=10), patients without nonrelaxing puborectalis syndrome (B2, n=30). The MMPI profiles were compared between subgroup patients. RESULTS: In overall patients, mean scores for scales HS, DP were elevated as compared with mean profiles (60~65 and 45~55, respectively). Male patients showed higher mean scores for scale SI than those of female patients (male vs. female; 63.5 vs. 53.9, P<0.05). A1 group showed higher mean scores for PD scale than those of A2 group (A1 vs. A2; 57.4 vs. 49.8, P=0.01). B1 group showed higher mean scores for DP scale than those of B2 group (B1 vs. B2; 67.5 vs. 59.8, P<0.05). CONCLUSIONS: Present series provided that the MMPI is a valuable tool for assessing the psychologic functioning of patients with chronic constipation. It has revealed a different personality and emotional composition in the subgroup patients based on the anorectal physiologic studies. An aspect of social introversion, psychopathic deviant and depression should be emphasized. These findings can provide the fundamental information for guideline of future diagnostic evaluation and therapy in the patients with chronic constipation.

PURPOSE: Even though many studies have indicated that the personality of medical students affects learning style and academic achievement, the effect of personality types on the performance skill tests has not been well known in the medical field due to the rarity of published papers. Thus, the aim of this study was to reveal the effect of personal traits on clinical skill performance tests. METHODS: Fifty-seven fourth-grade medical students were enrolled in this study. They had all completed clinical performance tests. To assess personality types, we used the Korean version of the Myers-Briggs Type Indicator (MBTI). RESULTS: Fifty-five of 57 senior medical students responded completely to the MBTI questionnaire. The proportion of four paired MBTI dimensions was Introversion (I)-Extroversion (E) (67.3% vs. 32.7%), Sensing (S)-Intuition (I) (76.4% vs. 23.6%), Thinking (T)-Feeling (F) (61.8% vs. 38.2%), and Judging (J)-Perception (P) (56.4% vs. 43.6%). The dominant personality types were ISTJ (23.6%), ESTJ (14.5%), and ISTP (10.9%). The first objective structured clinical examination (OSCE) test showed higher scores in Extraversion, Judging, and Sensing-Judging types compared to the counterparts (p<0.05), but this effect was not observed in the second OSCE test. On the clinical performance examination, Extraversion, Sensing, and Judging types had a higher score, as measured by standardized patients. CONCLUSION: Specific personal traits affect the test scores of the clinical performance skill examinations. So, personality measurement might be a useful tool for understanding a student who has difficulty in performance tests. We hope this study will give valuable information to examiners when they instruct and counsel students about clinical performance tests.

PURPOSE: The purpose of the study was to investigate the relationships between the Myers-Briggs Type Indicator (MBTI) psychological type and marital satisfaction, divorce proneness, positive affect, and conflict regulation in couple visiting a clinic. METHODS: Couples (n=62) who visited "M" couple clinic participated in the study. Data were collected from March to June 2009 using the Marital Satisfaction Scale, Marital Status Inventory, Positive Affect Inventory, and Conflict Regulation Inventory. RESULTS: The couples showed no significant differences in marital satisfaction, positive affect, and conflict regulation according to similarities between spouses in MBTI types. However, they showed significant differences in divorce proneness of husband according to a similarity in the Sensing/Intuition indicator. They also showed significant differences in divorce proneness, positive affect, and conflict regulation between the couples for ISTJ (Introversion, Sensing, Thinking, Judging) or ESTJ (Extraversion, Sensing, Thinking, Judging) types compared to other couples. CONCLUSION: When nurses counsel couples, they should understand that differences in psychological type between spouses affects their marital relationship. In addition, nurses should educate couples on the characteristics of each type according to the couple's types and help them to understand each other, especially for couples where one spouse is the ISTJ/ESTJ type. These interventions will improve marital satisfaction and prevent the divorce in these couples.

INTRODUCTION: The practicing of patient-centered medical services means a change in the pattern of the nature of doctor-patient relationship. The doctor oriented relationship is now moving to the pattern that patients resolve problems autonomously and participate in the decision-making in medical services. Authors performed this study to investigate the patient centeredness and influencing variables in medical students. METHODS: Authors recruited 94 medical students before psychiatric clinical clerkship and all subjects were assessed by structured questionales including socio-demographic data, frequency of receiving doctor-patient relationship lectures, Minnesota multiphasic personality inventory (MMPI), Meyers-Briggs type indicator (MBTI), the authoritarian personality scale (AP), job satisfaction scale (JS), patient practitioner orientation scale (PPOS), problem-solving decision-making scale (PSDM), and Beisecker locus of authority in decision-making scale (BLAS), and the questionnaire of JS, PPOS, PSDM, and BLAS were rechecked after psychiatric clinical clerkship. RESULTS: After psychiatric clinical clerkship, the score of JS, PPOS were higher than before. The group who had a good memory for taking a doctor-patient relationship lecture showed higher scores of the BLAS and PSDM than unexposed group. The AP was related with MBTI, correlated with the subscale of MMPI, however, inversely correlated with PPOS after psychiatric clinical clerkship. CONCLUSION: The authoritarian personality trait was related not only with other personality trait including introversion and psychopathic deviation (Pd) but also with patient-centeredness. Taking a lecture in doctor-patient relationship is positively related to the patient-centeredness.

PURPOSE: This study was done to examine the correlations between personality type and job satisfaction of nurses. METHODS: Subjects included three hundred twelve nurses ages from 21 to 55. The Myers-Briggs Type Indicator(MBTI) was administered to determine the personality types of the nurses(n=312). A job satisfaction survey including a demographic and career questionnaire was also used. Data were analyzed using ANOVA. RESULTS: The mean score for job satisfaction was 113.68 out of 205. The result showed that there was no statistically significant correlation between job satisfaction and information gathering functions ; S: Sensing, N: Intuition (t=.667, p=.499), T: Thinking, F: Feeling (t=.822, p=.412). The results, however, indicated that style for gaining energy(I: Introversion, E: Extroversion)(t=2.008, p=.046) and life dealing style(J : Judgement, P : Perception)(t=2.290, p=.023) were significantly correlated with job satisfaction. The extrovert focuses on the outside and get energy through interacting with people and doing things. Judgement type is described as organized, decisive, and orderly. CONCLUSION: Nurses in the extrovert and judgement types were more satisfied with their jobs than those in the introvert and perceptive type. Other results support that educational level, marital status, job characteristics, clinical experiences, motivation for nursing, and night duty were correlated with job satisfaction.

OBJECTIVES: The conversion of medical colleges into medical schools has been attempted by the Korean government since 2005. The aim of this study was to compare psychological characteristics of undergraduate and graduate medical students before and after changes in the medical educational system. METHODS: Four hundred-and-twenty-eight medical students participated in this study; 247 were undergraduates and 181 were graduate students. The participants completed psychological assessments including the Minnesota Multiphasic Personality Inventory (MMPI), the Symptom Checklist-90-Revision (SCL-90-R), the Beck Depression Inventory (BDI), and the Alexithymia Scale. RESULTS: Overall, undergraduate medical students demonstrated significantly higher scores than the graduate medical student on three of MMPI subscales (F, depression, and social introversion) and two of SCL-90-R subscales (somatization and obsessive-compulsive). When comparing the four groups (male undergraduate, female undergraduate, male graduate, female graduate) using analysis of covariance and controlling for age as a covariate, there were significant differences between male graduate and male undergraduate medical students in the same subscales except somatization, whereas there were no significant differences between female groups. CONCLUSION: These findings suggest that male graduate medical students may have better mental health states and less psychological problems than undergraduate medical students even after controlling for age. However, these differences were not found between female groups. Although every score of all items was within normal range regardless of group, distinctive differences between male graduate and undergraduate students were revealed for some psychological profiles such as depression, social introversion, and obsessive-compulsive traits.

PURPOSE: ADHD (Attention Deficit Hyperactivity Disorder) is a neurodevelopmental disorder with three characteristics, such as impulsivity, inattention, and hyperactivity symptoms. This is a common disease that the prevalence reaches 4-7% of all children. There are a variety of hypothesis in the pathogenic mechanisms and etiology. Parental psychopathology influences directly and indirectly on the occurrence of ADHD in children. The aim of this study was to evaluate the clinical and psychological characteristics of caregiver of child with ADHD using the MMPI (Minnesota Multiphasic Personality Inventory)-2. METHODS: The subjects consisted of 35 caregivers of patients with ADHD and 34 caregivers of children without neuropsychiatric disorders who visited to the pediatric neurology clinic of Kangnam sacred heart hospital from January 2009 to June 2011. We diagnosed ADHD according to DSM(Diagnostic and Statistical Manual of Mental Disorder)-IV criteria. We compared the psychologic characteristics between ADHD group and control group using T score of MMPI-2. RESULTS: MMPI T scores of caregivers of children with ADHD were significantly higher on the depression(D), psychasthenia(Pt), schizophrenia(Sc), social introversion (Si) scales than control group and most of scales were significantly higher in restructured clinical (RC) scale and personality psychopathology five (PSY-5) scales. CONCLUSION: The results suggested that psychopathology of caregivers might induce ADHD in the children. On the contrary, ADHD symptom of children might be associated with occurrence of psychopathology in the cargiver. In order to proper treatment of ADHD patient, we need to psychologic evaluation in the caregivers of patients with ADHD.

An attemption was made to estimate the effect of menopause on the mental health of climacteric women. The Minnesota Multiphasic Personality Inventory(MMPI) were questioned to 278 premenopausal women and 302 postmenopausal women. Data were analyzed by one-way analysis of variance in each variable of menopause, age, educational level, religion and partnership of husband, and two-way analysis of variance in two variables of menopause and one of other variables. The results were summarized as follows. 1. Menopause increased the scores of validity, psychopathic deviate, hypomania and paranoia scale, but conversely decreased the score of masculinity-femininity scale. 2. The older the climacteric women were, the lower scores of masculinity-femininity scale were observed. 3. The older the premenopausal women were, the higher scores of depression, hysteria, psychopathic deviate, psychasthenia and schizophrenia scale were observed, on the contrary, all scores of the postmenopausal women were decreased by the increment of their ages. 4. The higher the educational level of climacteric women were, the higher scores of correction and masculinity-femininity scale were observed, but the scores of hypochondriasis, hysteria, schizophrenia and social introversion scale were decreased by the increment of their educational level. 5. The scores of hypomania scale were higher in women of Buddhism than other religions. 6. The scores of validity, paranoia, psychasthenia, schizophrenia and social introversion scale were higher in windows than women with husband.
