OBJECTIVE: This study aims to explore factors affecting the dental aesthetic social psychology of patients with skeletal malocclusion and to measure the relationship between the objective orthodontic requirements and the subjective treatment requirements of patients. This work provides a reference for doctors to measure patients' orthodontic treatment needs. METHODS: Adult patients with skeletal malocclusion were chosen as the research object. Questionnaire survey was used to analyze factors influencing the psychosocial impact of dental aesthetics questionnaire (PIDAQ), index of orthodontic treatment need (IOTN), and Eysenck personality questionnaire-revised short scale for Chinese (EPQ-RSC). The relationship among PIDAQ, IOTN, EPQ-RSC, and treatment options was also evaluated. RESULTS: Seventy-two valid questionnaires were collected from adult patients with skeletal malocclusion. 1) The PIDAQ scores significantly differed among different occupations (P<0.05) but were not affected by other general conditions such as gender and age. 2) Patients of different dental health component (DHC) grade and ages had different AC self-assessment scores (P<0.01, P<0.05). The AC self-assessment score was positively correlated with the PIDAQ score (P<
0.05). 3) Males accounted for a higher proportion of patients who received treatment. Younger patients (18-28 years old) were more likely to receive treat-ment when their own dental aesthetics were poor. People with the higher monthly expenditure accounted for the larger proportion of surgical patients. 4) The PIDAQ score had no significant effects on the choice of opera-tion (P>0.05). People with low educational level were more likely to receive surgery if their psychosocial impacts of dental aes-thetics were serious. 5) The score of psychoticism scale of EPQ-RSC and the educa-tional level had a mutual influence on the PIDAQ score (P<0.01). Moreover, the neuroticism scale and AC self-assessment scores had a mutual influence on the PIDAQ score (P<0.05). However, this study did not find a correlation between personality traits and treatment options. CONCLUSIONS Many factors, such as personal natural conditions, subjective aesthetic evaluation of teeth, and psychosocial impacts of dental aesthetics, affect patients' treatment options. Personality characteristics can play a certain role in dental aesthetics social psychology.

Background: In Malaysia, the prevalence of adolescents’ suicidal ideation has increased over the years. Therefore, it is crucial to investigate the predictors of suicidal ideation among adolescents. Hence, the aim of this study was to examine the predicting effects of depression and self-esteem on suicidal ideation among Malaysian adolescents. In addition, the relationships between depression, self-esteem, and adolescents’ suicidal ideation were explored as well. Methods: By using a multistage cluster sampling method, a cross-sectional study was conducted in secondary schools in Kuala Lumpur, Malaysia. The participants were comprised of 852 adolescents (51% males and 49% females) aged 13-17 years old who completed self-administered questionnaires. Pearson’s Correlation analysis was used to analyse the relationships among depression, self-esteem, and adolescents’ suicidal ideation, while Standard Multiple Regression analysis was used to examine the predicting effects of depression and self-esteem on adolescents’ suicidal ideation. Results: Depression had a positive correlation with adolescents’ suicidal ideation (r = .290, p < .001), while self-esteem had a negative correlation with adolescents’ suicidal ideation (r = -.283, p < .001). Results also showed that both depression (β = .200, p < .001) and self-esteem (β = -.186, p < .001) significantly predicted adolescents’ suicidal ideation. Conclusion The study found that depression is a risk factor, while self-esteem is a protective factor of adolescents’ suicidal ideation.

PURPOSE: This study aimed to identify the degree of accident prevention behavior, self-esteem, self-regulation ability, and social support among middle-school students, and investigate factors influencing their practice of accident prevention behaviors.METHODS: The participants were 174 students from two middle schools located in J city. Data were collected from December 28, 2017 to February 9, 2018 using self-reported questionnaires.RESULTS: The mean score were 3.08±0.37 of 4 for practice of accident prevention behaviors, 3.07±0.57 of 4 for self-esteem, 3.69±0.48 of 5 for self-regulation ability, and 3.38±0.75 of 5 for social support. Positive correlations were found among self-regulation ability, self-esteem, social support, and practice of accident prevention behaviors. The factors influencing the practice of accident prevention behaviors were personality (being ‘haste’) (β=−.20, p=.003), self- regulation ability (β=.48, p<.001), and social support (β=.23, p<.001). These factors explained 39.0% of the variance in practice of accident prevention behaviors.CONCLUSION: It was found that the middle-school students engaged in prevention behavior to an extent that was insufficient to prevent accidents. Therefore, it is necessary to develop intervention strategies to improve the practice of accident prevention behavior among middle-school students, considering self-regulation ability, social support, and personality, which affect the practice of accident prevention behaviors.

PURPOSE: The purposes of this study were to investigate relationships of depression, hopelessness, self-esteem, and social support with suicide ideation and to identify factors associated with suicidal ideation of elderly people.METHODS: A descriptive correlational study was conducted with 100 elderly people residing in a community setting. Data were collected in September 2019 through structured questionnaires to assess depression, hopelessness, self-esteem, social support, and suicide ideation. Data were analyzed using descriptive statistics, t-test, one-way ANOVA with Scheffé test, Pearson's correlation coefficients, and hierarchical regression analyses.RESULTS: Presence of spouse (t=−3.32, p < .001), satisfaction in children relationships (F=3.56, p=.032), overall life assessment (F=3.94, p=.023), and pain/ill-being (t=−2.04, p=.043) showed significant differences in suicidal ideation. Suicidal ideation and self-esteem were negatively correlated (r=−.49, p < .001). Depression and suicidal ideation(r=.56, p < .001) and hopelessness and suicidal ideation (r=.49, p < .001) were positively correlated. Factors of suicidal ideation of elderly people were depression (β=.36, p=.017) and self-esteem (β=−.21, p=.046), that explained 30.1% of the total variance in the proposed model.CONCLUSION: A community intervention programs for preventing suicide among elderly people should include nursing strategies about depression and self-esteem. In addition, partnership with elder's spouse could be helpful to reduce suicidal ideation.

OBJECTIVE: Alcohol drinking can cause various psychiatric and medical diseases. Although women generally consume less alcohol than men, they may be at a greater risk for alcohol-related psychological distress. The aim of the current study is to evaluate whether the association between alcohol consumption and psychological distress, including stress, depressed mood, and suicidal ideation and the risks of psychological distress differ based on gender. METHODS: The cross-sectional study included 31,657 participants (17,915 women and 13,742 men) from the 2010–2013 and 2015 Korea National Health and Nutrition Examination Survey. Alcohol drinking and Alcohol Use Disorders Identification Test (AUDIT) levels were assessed for evaluating the amount of alcohol intake and alcohol-related problems. Self-perception of stress, depressed mood, and suicidal ideation were assessed for evaluating psychological distress. Odds ratio and 95% confidence intervals for psychological distress were calculated using multiple logistic regression models. RESULTS: The risks of psychological distress were not significantly associated with drinking level in both sexes. However, the risks of psychological distress were associated with an increase in AUDIT levels, and there were gender differences in the psychological consequences of alcohol-related problems. The association was more drastic in women, and women showed a significant association even though the severity of drinking problem was low with the exception of stress perception. CONCLUSION: The risks of psychological distress were associated with the severity of alcohol-related problems and women were more likely to be susceptible. Therefore, it is recommended that women even at low-risk for problematic drinking should be screened for psychological distress.

PURPOSE: This study investigated differences in the relationships of factors including emotional problems, self-perception, parental behavior, and peer attachment with smartphone dependency (SD) among middle school, high school, and college students in South Korea. METHODS: This study used data from a nationwide sample of 1,882 middle school, 1,821 high school, and 1,346 college students who owned smartphones. Descriptive statistics and multiple regression analysis were conducted to investigate the predictors of SD based on school level. RESULTS: SD scores significantly differed across school levels. Female gender, more aggressive behavior, less ego-identity, and less monitoring parental behavior were linked to higher SD at all school levels. Less self-esteem and intrusive parental behavior were linked to SD in middle school students. In high school students, additional factors related to higher levels of SD were resilience, intrusive / inconsistent parental behavior, peer trust and alienation, and depression. Additionally, resilience, over-expectant parental behavior, and peer trust were linked to higher SD in college students. CONCLUSION: This study provides insights into SD and predictors of SD among middle school, high school, and college students. Based on these findings, SD prevention programs should be developed according to the developmental stages of adolescents and young adults.

PURPOSE: The purpose of this study was to identify factors associated with career maturity among Korean high school students. METHODS: A descriptive cross-sectional design was adopted using secondary data from the 2012 Korean Welfare Panel Study (KoWePS). The participants were 496 high school students who completed the supplemental survey for children, which included items on career maturity, self-esteem, study stress, teacher attachment, relationship with parents, peer attachment, depression and anxiety. Descriptive statistics, the chi-square-test, the t-test, and a decision tree were used for data analysis. RESULTS: The decision tree identified five final nodes predicting career maturity after forcing self-esteem as the first variable. The highest predicted rate of high career maturity was associated with high self-esteem, experience of career counseling, and high teacher attachment. The lowest predicted rate of high career maturity was associated with low self-esteem and low attachment to friends. CONCLUSION: Factors influencing career maturity were varied by levels of self-esteem in Korean high school students. Thus, it is necessary to develop different approaches to enhance career maturity according to levels of self-esteem.

PURPOSE: The aim of this study was to develop a structural model based on Bronfenbrenner's ecology of human development theory, that illustrates relationships of happiness and associated factors among Korean college students. METHODS: Study participants were 357 college students recruited from five universities throughout the convenience sampling. Self-reported data were collected from November, 2018 to January, 2019. The data were analyzed using descriptive statistics, Pearson's correlation coefficients, and a structural equation modeling in order to identify factors associated with college students' happiness. RESULTS: The tested model demonstrated the acceptable model fit compared to the hypothesized model, that explained college students' happiness with 68.7% accuracy. Positive family function, high self esteem and ego-resilience were significant factors associated with happiness for college students. However, positive friend support was not significant in our model. CONCLUSION: Our study findings suggest that both family and individual interventions are required to reduce negative emotions and increase happiness of college students. In particular, multicomponent interventions should include the concepts of self esteem, ego-resilience, and family function in terms of assessment and intervention contents tailored to Korean college students.
