Purpose: The purpose of this study was to identify the factors that affect depression among elderly people with, and without, dementia. Method: The participants were 903 people who were 65 or older and resided in Sungnam City. Data were collected from April to July 2002 using a questionnaire. The collected data were analyzed using descriptive statistics and hierarchical multiple regression aided by SPSS/PC. Result: The variables at the final step of the regression equation accounted for 28.2% of variance in the dementia group, 21.4% in the group with suspicious dementia, and 18.9% in the normal group. The multiple regression analysis revealed that ADL and instrumental support were related significantly to depression in the dementia group. Self-rated health, IADL, social activity support, and instrumental support were significantly related to depression in the group with suspicious dementia. In the normal group, education, self-rated health, and living arrangement with family were significantly related to depression. Conclusion: Social support and health condition are important to decrease depression in elderly people with dementia.

Objectives: The main purpose of this study was to examine how family strengths affect friend attachment and psychological well-being among college students and to analyze the relative influence of these two variables on psychological well-being. Method: Data were collected by self-administered questionnaire method from 362 university students in four different regions. The data were analyzed through various statistical methods such as t and F tests, Pearson's correlation analyses, and multiple regression analyses. Results: First, there were significant differences in the level of psychological well-being according to gender and the monthly family income, showing that males and higher family income group reported greater psychogocal-well-being level. Males also reported lower level of anxious attachment. Second, correlational analyses results indicated that college students' psychological well-being was positively related with family strengths and secure attachment, and was negatively correlated with avoidant and anxious attachment. Finally, the results of hierarchical multiple regression analyses indicated that college student's psychological well-being was influenced by family communication, secure attachment, and anxious attachment, showing that anxious attachment was the most influential variable. Conclusions: This study suggests the importance of providing education and/or counseling services focusing on strengthening the positive relationship with their friends and on increasing the family communication for college students' psychological well-being.

Background: Traffic injuries have become a significant public health problem in low- and middle-income countries. Several studies have examined the role of personality and attitude toward traffic safety in predicting driving behaviors in diverse types of drivers. Few studies have investigated risky behavior among public passenger van drivers. This study aims to identify the predictors of self-reported risky driving behavior among public van drivers. Method: A total of 410 public van drivers were interviewed at terminal stations in Bangkok. Hierarchical regression models were applied to determine the effects of demographics, personality traits, and attitude on self-reported risky driving behaviors. Results: The results indicated that drivers with a high education level, more working days, and high scores for normlessness and anger were more likely to report risky driving behaviors (p < 0.05). Conclusion: The personality traits and attitude toward speeding account for aberrant self-reported risky driving behavior in passenger van drivers. This could be another empirical basis for evidence-based road safety interventions in the context of public transport.

Internet addiction in adolescents is an important social issue. In this study, sparse partial least-squares regression (SPLS) was applied to internet addiction data in Korean adolescent samples. The internet addiction score and various clinical and psychopathological features were collected and analyzed from self-reported questionnaires. We considered three PLS methods and compared the performance in terms of prediction and sparsity. We found that the SPLS method with the hierarchical likelihood penalty was the best; in addition, two aggression features, AQ and BSAS, are important to discriminate and explain latent features of the SPLS model.

Objectives: The purpose of this study is to find the determinants of suicide impulse of residents living in mining region and other areas in one city. The past studies did not examine the suicide related attitudes or behaviors in mining region. This study also examines how coping resources and behaviors moderate the suicide impulse. Methods: For this purpose, hierarchical logistic regression method was used to predict the likelihood of suicide impulse. The personal characteristics, depression, coping resources and behaviors were considered as the independent variables. The data collected in this study was gathered through questionnaire survey with 502 residents in other areas as well as mining area in one city. Results and Conclusion: The results and conclusions are as follows: 1. The chi-square test revealed that residents living mining region showed higher percentage of suicide impulse compared to other areas. 2. The t-test revealed that those with suicide impulse had higher level of depression compared to those without it. This pattern was consistent in other areas as well as mining region. 3. The hierarchical logistic regression revealed that age, education, depression showed positive effect on suicide impulse in mining region. However, in other areas, education, illness, and depression showed positive effect on suicide impulse. Also, this result implies that suicide prevention efforts should be actively made in mining region.

Objectives: The purpose of this study was to examine the effects of parent-young adult relationship and self-differentiation on interpersonal problems among 20s. Method: The subjects were 504(195 male, 309 female) young adults in their twenties. The questionnaire was consisted of measures on the Parent-Child Relationship Instrument, Self-Differentiation Inventory, and Short form of Korean Inventory of Interpersonal Problems Circumplex. Descriptive, t-test, correlation, and hierarchical regression analyses were conducted with SPSS 23.0. Results: The major findings are as follow. First, the result showed that there were gender differences in the level of self-differentiation and interpersonal problems, while there were no differences between male and female in parent-young adult relationship. Second, correlational analyses results indicated that parent-young adult relationship was positively related with the level of self-differentiation. However parent-young adult relationship and the level of self-differentiation were negatively related with the interpersonal problems. Third, hierarchical regression analyses showed that parent-young adult relationship and the level of self-differentiation had significant influences on the interpersonal problems(moving toward people, moving against people and moving away from people among 20s). Conclusions: The results indicate that both parent-young adult relationship and the level of self-differentiation need to be considered to reduce young adults' interpersonal problems in counseling situations.

Objectives: The study aims to examine the influence of university students' sociodemographic variables, parents' variables, and personal variables on their level of depression. Method: The study included a total of 334 university students enrolled in Busan. The data were used to perform correlational analysis and hierarchical regression analysis and were processed using the SPSS 23.0 program. Results: The main results of this study were as follows: First, the hierarchical regression analyses revealed that the most influential model was the model of personal variables. Among the personal variables, self-esteem was the most influential factor responsible for university students developing depression - the higher their level of self-esteem, the lower their level of depression. Among the parent variables, attachment to their father was the second most significant influence on the depression level of university students. Conclusions: This study showed that, in addition to attachment to their father, their self-esteem was highly significant in predicting university students' depression. The results of these findings have implications for future research in the form of programs and education to improve the relationship with fathers. Furthermore, the results of this study could be used to help and provide basic resources to alleviate and prevent university students' depression by strengthening their self-esteem.
