Abstract
Procrastination, defined as delaying the task that needs to be completed until last minute, is a prevalent phenomenon in current society. It not only interferes with goal achievement but also makes people miss various opportunities in life and causes detrimental effect on mental health. However, little attention has been given to procrastination until early 1990s; investigation on various aspects, causes, and treatment of procrastination started only recently. Although numerous empirical studies have been accumulated since previous decades, there were limitations in integrating the results because the researches were conducted without sufficient agreement on the construct of procrastination. Therefore, the present study provided a comprehensive and critical review on the definition, classification, and measurement of procrastination, which are the key elements and foundation of procrastination research. We revisited various definitions and classifications of procrastination and discussed the limitation of each perspective. In addition, the development process, psychometric properties, and limitations of the measures of procrastination were reviewed. Suggestions for future studies were discussed.
Abstract
Social relationships and social networks have significant influence on individuals’ beliefs and behaviors. Through ongoing and dynamic social interactions, individuals connect with similar others and socialize their attributes. Although extensive research has investigated the interdependent changes of social networks and individual attributes, most research has focused on networks of friends. The current study examined and compared the network structural features, social interaction, and social influence between early adolescents’ friend and help networks. Results with longitudinal social network analysis indicated that friend networks were characterized by high density and peer group clusters, while help networks were characterized as loose-knit networks with high centrality. Also, homophily selection was more salient in the friend networks, while the magnitude of social influence did not vary between the two networks. Results underscore that examining structural features of social networks as well as considering different social ties are important for advancing our understanding of social influence processes.
Abstract
This study developed the Defensive Verbal Scale (DVS) to measures one's self-deceptive speech that protects self-concept from threatening information and examined its psychometric properties. First, operational definition of Defensive Verbal was defined. Following the literature review, 4 situations where one's self-concept might be threatened were derived: (1) situation where anger or painful experience arise, (2) situation where working outside one's belief or conscience is required, (3) situation where results are different from one's expectation, (4) situation where repeated mistakes or faults are negatively evaluated and items were constructed for each situations. On a preliminary survey, responses of 106 people aged 14-24 (male 53 and female 53) were reviewed to examine psychometric properties. As a result, a single-dimensional structure was explored and a high internal consistency(Cronbach’s α) was found. Situations and items that are not significant were eliminated based on convergent and discriminative validity analysis. As a result, a situation in which the threat of self-concept is common and anger or painful experiences related to physiological changes caused by stress arise, and a situation where repeated mistakes or faults are negatively evaluated, and 5 items for respective situations were selected. To evaluate psychometric properties of the confirmed DVS, two main surveys were done and principal component analysis, item analysis, internal consistency, test-retest reliability, convergent and discriminative validity were analyzed on each surveys. The result showed a single-dimensional structure and stable reliability. Whereas interpersonal sensitivity, low self-regulation, negative emotions and rationalization showed significant positive correlation, positive emotions and mindfulness showed significant negative correlation. This result verified convergent and discriminative validity. Finally, the significance and implications of the research and suggestions for future studies were discussed.
Abstract
Korea has a serious social problem in that about 5.2 workers die every day because of occupational accidents despite continuous efforts to reduce occupational accidents. And the occupational accidents are stagnant currently. In particular, the fact that not only machinery or physicochemical factors, which occupational safety and health (OHS) experts have been focusing on, but also human behaviors are also being considered as important causes of occupational accidents in recent years leads to concerns about the necessity of psychology and its role. Therefore, this study tried to identify the current status of OHS field and psychology field through literature. After then, the applicability of psychology to the domestic occupational safety and health act, the introduction for cases of occupational health psychology (OHP) in advanced foreign countries such as how to connect between OHS and psychology, and the interest of psychosocial risks in workplace through the analysis of Korea Occupational Safety and Health survey (KOSH) were conducted. As a result of KOSH survey analysis, the larger the size, the higher the demand for psychological approaches at workplace and it was found that the solution of psychosocial risks was more difficult than other safety and health problems. It was also found that the utilization of professional manpower by psychologists compared to occupational medicine doctor, preventive medicine doctor, nurse, or occupational safety and health experts was low. In this regard, preparing the relevant legal basis to involve psychologists in the workplace, the collaboration between existing OHS experts and psychologists, and the necessity of efforts at the level of the Korean Psychological Association and the department related to psychology in the universities were suggested. It is expected that psychology will find a way to become a subject in occupational safety and health field through OHP.
