OBJECTIVES: This study aimed to examine the relationships among maternal object relations, personality, and symptoms of children with ADHD. METHODS: The study's participants were 72 children with ADHD and their mothers. We used the Bell Object Relation Inventory (BORI), Minnesota Multiphasic Personality Inventory (MMPI), and Korean Personality Inventory for Children (KPI-C) to assess each child's maternal object relations, personality, and symptoms. RESULTS: The T scores of the pathologic group (PG) were higher than those of the normal group (NG) on the MMPI's D, Pa, Sc, Ma, and Si scales. The PG also had higher T scores than did the NG in delinquency, hyperactivity, family interaction, and autism on the KPI-C. Alienation in the PG was positively associated with hyperactivity and family interaction. The PG's egocentricity was positively associated with hyperactivity, family interaction, and autism. However, the NG was not associated with KPI-C. Per a stepwise multiple regression analysis, alienation was the most potent variable for hyperactivity, and egocentricity was the most critical variable for family interaction. CONCLUSION: These results show that the PG had a greater possibility of having personality problems than did the NG. In particular, alienation and egocentricity with regard to maternal object relations were the most decisive variables in children's symptoms.

PURPOSE: The aim of this study was to compare patient-centeredness changes between medical school graduates and medical students after a psychiatric clinical clerkship. METHODS: We focused on 40 medical school graduates. We received permission to use data from a 2006 study on patient-centeredness of 94 medical students. The following was repeated before and after clerkship: Minnesota Multiphasic Personality Inventory (MMPI), Meyers-Briggs type indicator (MBTI), Patient-practitioner Orientation Scale (PPOS) and Authoritarian Personality (AP) scale. RESULTS: In the 2006 study on patient-centeredness of medical students, the AP scores were significantly lower than before clerkship and the PPOS scores were significantly higher than before clerkship. AP score changes were related to MBTI, correlated with MMPI subscales, but inversely correlated with PPOS changes. In this study, the change in PPOS scores was not significant after clerkship in case of medical school graduates. AP score changes inversely correlated with PPOS changes, but neither correlated with MMPI subscales or MBTI. CONCLUSION: Considering previous findings, medical school graduates tend to be more patient-centered than medical students, but medical students can adopt a more patient-centered attitude than graduates through a psychiatric clinical clerkship.

OBJECTIVES: This study was conducted to compare characteristics of parents of attention-deficit hyperactivity disorder (ADHD) children in relationship to treatment compliance. METHODS: A total of 271 school-aged children diagnosed with ADHD were devided into two groups by treatment duration; early dropout group (n=117, treatments discontinued within three months) and continuous treatment groups (n=154, treatments continued for more than three months). Scores on the Korean Personality Inventory for Children (KPI-C), Minnesota Multiphasic Personality Inventory (MMPI), Korean Parenting Sense of Competence (K-PSOC), Korean Parenting Stress Index-Short Form (K-PSI-SF), and Parental Acceptance Rejection Questionnaire (PARQ) were compared between two groups. RESULTS: According to the results of the KPI-C, parents of the early dropout group showed a higher tendency to regard their children's symptoms as 'somatization' and 'delinquency', compared with those of continuous treatment groups (49.9 vs. 46.3 and 60.9 vs. 58.2, p=0.048 and 0.046, respectively). Parents in the early dropout group showed higher scores on hypochondriasis and psychasthenia subscales in MMPI (54.7 vs. 52.1 and 51.5 vs. 48.5, p=0.024, and 0.017, respectively). The results of the K-PSOC showed that parents in the early dropout group perceived a lower sense of parenting competence (27.3 vs. 58.6, p=0.047). CONCLUSION: Our findings suggested that characteristics of the parents and their perspectives regarding children's symptoms could be possible factors associated with treatment compliance in ADHD. Further researches on this issue may provide opportunities to improve treatment compliance for children with ADHD.

OBJECTIVES: The symptomatic and behavioral correlates of childhood trauma in schizophrenia are beginning to emerge in the literature. This study aimed to investigate whether the association between personality traits and schizophrenia with childhood abuse can be replicated in Koreans using the Multiphasic Minnesota Personality Inventory (MMPI). METHODS: Eighteen schizophrenias with childhood abuse and 24 schizophrenic comparisons without abuse history were recruited at the inpatient units of two general hospitals and the subjects completed the MMPI. RESULTS: Subjects with schizophrenia plus childhood history of abuse had less educational years (p<.001). After controlling the educational year as a covariate, abused schizophrenic patients had higher scores in the Schizotypal (p=.003), Dependent (p=.014), Passive-aggressive (p=.034), Borderline (p=.045) subscales. For the validity and clinical subscales, significant differences were found in the F scale (p=.036), Hypochondriasis (p=.042), Depression (p<.001), Hysteria (p=.002), Personality disorder (p=.001), Paranoia (p=.024), Psychasthenia (p=.001) and Schizophrenia (p=.006) subscales. CONCLUSION: Our findings suggest that childhood abuse in schizophrenia is associated with more complex features of personality characteristics rather than specific cluster B personality traits.

PURPOSE: The aim of this study was to investigate attitudes toward death according to personality types and to suggest the need to develop related hospice programs. METHODS: Personality types were identified by the Korean version of the Myers-Briggs Type Indicator (MBTI) Form G. A questionnaire with 26 five-point Likert items was used to survey participants' attitudes toward death. RESULTS: The ESFP personality type was most common (20%) among available 100 participants. Significant differences were observed in the attitudes towards death preparation according to personality type s. Participants with personality preference types E, T and J showed positive attitudes (P<0.05) toward death, but no significant differences were shown based on the SN index. CONCLUSION: The attitudes toward death differed by personality types. Therefore, this study points to the need to develop diverse hospice programs based on the personality types.

OBJECTIVES: To explore the occurrence and the differences of clinical manifestations of organic personality disorder with varying degrees of craniocerebral trauma. METHODS: According to the International Classification of Diseases-10, 396 subjects with craniocerebral trauma caused by traffic accidents were diagnosed, and the degrees of craniocerebral trauma were graded. The personality characteristics of all patients were evaluated using the simplified Neuroticism Extraversion Openness Five-Factor Inventory （NEO-FFI）. RESULTS: The occurrence rate of organic personality disorder was 34.6% while it was 34.9% and 49.5% in the patients with moderate and severe craniocerebral trauma, respectively, which significantly higher than that in the patients （18.7%） of mild craniocerebral trauma （P<0.05）. Compared with the patients without personality disorder, the neuroticism, extraversion and agreeableness scores all showed significantly differences （P<0.05） in the patients of mild craniocerebral trauma with personality disorder; the neuroticism, extraversion, agreeableness and conscientiousness scores showed significantly differences （ P>0.05） in the patients of moderate and severe craniocerebral trauma with personality disorder. The agreeableness and conscientiousness scores in the patients of moderate and severe craniocerebral trauma with personality disorder were significantly lower than that of mild craniocerebral trauma, and the patients of severe craniocerebral trauma had a lower score in extraversion than in the patients of mild craniocerebral trauma. CONCLUSIONS The severity of craniocerebral trauma is closely related to the incidence of organic personality disorder, and it also affects the clinical features of the latter, which provides a certain significance and help for forensic psychiatric assessment.

OBJECTIVE: Meditation can elicit trait-like changes in psychological and social styles, as well as enhancement of emotional regulatory capacity. We investigated the relation between personality traits and emotional intelligence in meditation practitioners. METHODS: Seventy-two long-term practitioners of mind-body training (MBT) and 62 healthy comparative individuals participated in the study. The participants completed emotional intelligence questionnaires and the Myers-Briggs Type Indicator (MBTI). RESULTS: The MBT group revealed higher scores on all five emotional intelligence factors than did those in the control group, such as emotional awareness and expression, empathy, emotional thinking, emotional application, and emotional regulation (all p≤0.001). MBT practitioners also had higher scores on the intuition of perceiving function (t=−2.635, p=0.010) and on the feeling of the judging function (t=−3.340, p=0.001) of the MBTI compared with those in the control group. Only the MBT group showed a robust relationship with every factor of emotional intelligence and MBTI-defined intuitive styles, indicating that higher scores of emotional intelligence were related to higher scores for intuition. CONCLUSION: Emotional intelligence of meditation practitioners showed notable relationships with some features of personality trait. In-depth associations between emotional intelligence and personality traits would help to foster psychological functions in meditation practitioners.

BACKGROUND/OBJECTIVES: A healthy diet has been reported to be associated with physical development, cognition and academic performance, and personality during adolescence. This study was performed to investigate the relationships among milk consumption and academic performance, learning motivation and strategies, and personality among Korean adolescents. SUBJECTS/METHODS: The study was divided into two parts. The first part was a survey on the relationship between milk consumption and academic performance, in which intakes of milk and milk products and academic scores were examined in percentiles among 630 middle and high school students residing in small and medium-sized cities in 2009. The second part was a survey on the relationships between milk consumption and learning motivation and strategy as well as personality, in which milk consumption habits were collected and Learning Motivation and Strategy Test (L-MOST) for adolescents and Total Personality Inventory for Adolescents (TPI-A) were conducted in 262 high school students in 2011. RESULTS: In the 2009 survey, milk and milk product intakes of subjects were divided into a low intake group (LM: ≤ 60.2 g/day), medium intake group (MM: 60.3-150.9 g/day), and high intake group (HM: ≥ 151.0 g/day). Academic performance of each group was expressed as a percentile, and performance in Korean, social science, and mathematics was significantly higher in the HM group (P < 0.05). In the 2011 survey, the group with a higher frequency of everyday milk consumption showed significantly higher "learning strategy total," "testing technique," and "resources management technique" scores (P < 0.05) in all subjects. However, when subjects were divided by gender, milk intake frequency, learning strategy total, class participation technique, and testing technique showed significantly positive correlations (P < 0.05) in boys, whereas no correlation was observed in girls. Correlations between milk intake frequency and each item of the personality test were only detected in boys, and milk intake frequency showed positive correlations with "total agreeability", "organization", "responsibility", "conscientiousness", and "intellectual curiosity" (P < 0.05). CONCLUSION: Intakes of milk and milk products were correlated with academic performance (Korean, social science, and mathematics) in Korean adolescents. In male high school students, particularly, higher milk intake frequency was positively correlated with learning motivation and strategy as well as some items of the personality inventory.

OBJECTIVE: The prevalence of depressive symptoms has become a significant public health issue in China. Research on the relationship between personality traits and changes in depressive symptoms, as well as further exploration of urban-rural differences, not only benefits for the understanding of the prevalence trend of depression in China, but also provides a useful reference for the government to develop personalized mental health prevention strategies. METHODS: Based on the data from the China Family Panel Studies in 2018 and 2020, a univariate analysis was conducted on 16 198 Chinese residents aged 18 years and above. Five dimensions of personality traits were conscientiousness, extraversion, agreeableness, neuroticism and openness. In the study, 16 198 residents were divided into "keep good group", "better group", "worse group" and "keep bad group" according to the changes in depressive symptoms in 2018 and 2020. After controlling for factors, such as gender and education, multinomial Logistic regression analysis was used to examine whether personality traits were associated with changes in depressive symptoms. In addition, we evaluated whether urban-rural and personality traits interacted to influence depressive symptoms. RESULTS: The five dimensions of personality traits were significantly correlated with changes in depressive symptoms. Conscientiousness, extroversion, and agreeableness were negatively associated with depressive symptoms, while neuroticism and openness were positively related. Urban and rural differences moderated the relationship between personality traits and depressive symptoms. Compared with urban residents, rural residents showed stronger correlations between neuroticism (OR=1.14; 95%CI: 1.00-1.30) and the group of depression-recovery, as well as conscientiousness (OR=0.79;95%CI: 0.68-0.93) and the group of persistent-depression. CONCLUSION The study finds that personality traits have a significant correlation with changes in depressive symptoms, with certain traits showing a negative or positive relationship. Specifically, higher levels of conscientiousness, extraversion, and agreeableness are associated with lower levels of depressive symptoms, while higher levels of neuroticism and openness are associated with higher levels of depressive symptoms. In addition, the study finds that rural residents have a stronger association between their personality traits and persistent or improved depressive symptoms, which highlights the need for tailoring mental health intervention and prevention programs that should take into account personality traits and urban-rural differences in China. By developing targeted strategies that are sensitive to personality differences and geographic disparities, policymakers and mental health professionals can help prevent and reduce the incidence of depressive symptoms, ultimately improving the overall well-being of Chinese adults. Meanwhile, additional studies in independent populations are needed to corroborate the findings of this study.
