The purpose of this study is to test the psychometric properties of the Korean version of the Health-Related Hardiness Scale(HRHS) in a sample of Korean nursing students. The korean version of HRHS was administered to 234 nursing students including 135 college students and 99 university students. The Korean version of HRHS was measured on a 6 Likert scale, assessing three factors of HRHS : control, commitment, and challenge. Internal consistency was used to test the instrument's reliability. The internal consistency of the scale was measured using a coefficient alpha. The coefficient alpha was .69(control), .49(commitment). and .69(challenge), Item analysis and confirmatory factor analysis (CFA) were used to test the instrument's construct validity. The item analysis identified that there were 13 items. which were lower than the .25 item-total correlation. CFA revealed that the scale's fadoral validity was not proper by showing unfit indices(RMSEA .07. stand, RMR .09. GFI .71). According to the findings of this study, the reliability and construct validity of the Korean version of HRHS is not satisfactory in the sample of nursing students. As a result. the researcher modified the scale through item analysis and repetitive CFA process, and proposed the revised 25-item Korean version of HRHS for nursing students. The revised scale's reliability(control .74, commitment .73. challenge .77) and factorial validity were within acceptable levels. The item analysis identified that there was no item, which is lower than the .25 item-total correlation. CFA revealed that the scale's factoral validity was proper by showing fit indices(RMSEA .08 stand. RMR .08. GFI .80).

Purpose: The aims of this study were to examine the trend of quantitative study in Korean Journal of Adult Nursing published between 1989-2011 and to provide future directions for nursing research in adult health nursing. Methods: A total of 883 published articles were reviewed, and main subject and the methodology were analyzed using descriptive statistics. Results: The most frequently cited keywords were elderly, quality of life, depression, knowledge, stress and anxiety. The survey study was the most popular research design (67.6%) followed by experimental (26.5%), and methodological study (5.5%) design. Over 80% of studies with translated or developed instruments reported reliability for psychometric analysis, while only 18% of the studies reported validity of the instruments they used. In the periods of 2006~2011, significantly more studies utilized experimental design, obtained IRB approval and written consent, and included power analysis for sample size calculation. In recent experimental study, educational program and complimentary therapy were the two most frequently used interventions. Conclusion: Through the analysis of nursing studies published in Korean Journal of Adult Nursing, we found the number of experimental studies has increased and methodological rigor has improved in recent years.

Purpose: The purpose was to determine the content validity of a semantic revision of items on a reliable and valid instrument, the Sieloff-King Assessment of Group Outcome Attainment (Power) within Organizations in Korea (K-SKAGOAO). Methods: The target population for research was chief nurse officers (CNOs) of all hospital within Korea. A sample of 303 hospitals from across the Korea was selected through a stratified random sampling process. A total of 174 CNOs comprised the final sample. Psychometric evaluation of the K-SKAGOAO included: (a) criterion-related validity (b) factor analysis and (c) internal consistency reliability using Cronbach's alpha coefficients. Results: The Convergent validity and criterion-related validity were supported. Cronbach's alpha coefficient for the K-SKAGOAO was .95. Subscale alphas ranged from .60 to .86. Conclusion: The K-SKAGOAO and related subscales show validity and internal reliability. A nursing group of any size can use the K-SKAGOAO to both assess the group's level of outcome attainment and develop strategies to further improve that level.

Purpose: The process of designing a questionnaire is complicated. Many questionnaires on nursing phenomena have been developed and used by nursing researchers. The purpose of this paper was to discuss questionnaire design and factors that should be considered when using existing scales. Methods: Methodological issues were discussed, such as factors in the design of questions, steps in developing questionnaires, wording and formatting methods for items, and administrations methods. How to use existing scales, how to facilitate cultural adaptation, and how to prevent socially desirable responding were discussed. Moreover, the triangulation method in questionnaire development was introduced. Results: Steps were recommended for designing questions such as appropriately operationalizing key concepts for the target population, clearly formatting response options, generating items and confirming final items through face or content validity, sufficiently piloting the questionnaire using item analysis, demonstrating reliability and validity, finalizing the scale, and training the administrator. Psychometric properties and cultural equivalence should be evaluated prior to administration when using an existing questionnaire and performing cultural adaptation. Conclusion: In the context of well-defined nursing phenomena, logical and systematic methods will contribute to the development of simple and precise questionnaires.

Purpose: In this study, relationships between symptom experience and quality of life in a cross-sectional sample of patients with Atrial Fibrillation (AF) were investigated. Methods: This descriptive study involved a convenience sample of AF patients from S university hospital, C city. One hundred and two AF patients completed psychometric validated measures of AF related symptoms and quality of life. Descriptive statistics and Pearson correlation coefficients with SPSS WIN 14.0 were used for data analysis. Results: Of 16 atrial arrhythmia-related symptoms, the patients reported 'tiredness' as the most frequent and 'shortness of breath' as the most severe. The level of overall quality of life for patients with AF was 53.92. There were significant differences in symptom frequency according to religion, New York Heart Association (NYHA) classification and left ventricular ejection fraction ; symptom severity according to monthly income and stroke ; quality of life according to age, job, alcohol intake, NYHA class and stroke. Quality of life for these patients was positively correlated with symptom frequency and symptom severity. Conclusions: This study demonstrated that patients with more frequent and severe symptoms perceive poorer quality of life than patients with less frequent and less severe symptoms. Symptom experience should be assessed early to improve quality of life for patients.

The Dynamic Gait Index (DGI) was developed and widely used as a clinical tool to assess balance performance during gait. The purpose of this study was to validate the Korean translated DGI using Rasch analysis. A total of 105 community-dwelling elderly was participated in this study (age range = 65~95 years; mean = 78.0 years). The translated DGI showed sound item psychometric properties, and the 8 items were arranged in order of difficulty for the total participants. The most difficult item was 'Steps' and the easiest item was 'Level surface'. Also, each of the original 4 rating scale categories satisfied the Linacre's essential criteria suggestions for optimal rating scale category effectiveness. Although, thirty eight person (36.2%) showed the maximal high score, but the most of them was no history of fall in the preceding year. For subjects who has falling history, all of the person's ability was arranged within the item's difficulty. The 8-item Korean translated DGI can be used to measure gain in elderly person with balance disorders without compromising important clinical measurement characteristics in Korea.

As the e-business developed fast and more firms embrace CRM as a core e-business strategy, it is getting more important to assess the firms. The CRM is approaching customer-centric. This approach focuses on the long-term relationship with the customers by providing the benefits of the customer rather than based on what the company wants to sell. How to establish the overall efficiency and effectiveness of a global enterprise becomes more and more important to the E-business. The study investigates the cross-national psychometric prosperities of the establishment in the E-business. Using a cross-national survey of customers from Korea and China to compare the Korean customers' acceptance of e-business with the Chinese customers', and compare the development of e-business in Korea with the development in China it will be found that Korea and China samples shared a somewhat similar factor structure. And there are also some differences between Korea and China. These findings suggest that the way to establish the e-business strategy is influenced by the cultural effects. So focusing on the cultural differences among the countries becomes more and more important, this study will help to analysis how to use the different cultural dimension to establish the better CRM system in the e-business field.

The purpose of this study was to examine the psychometric property of the Children's Behavior Questionnaire(CBQ), including reliability, content validity, construct validity, cross validity, and concurrent validity with EAS(Emotionality, Activity, Sociability) scale. The CBQ is a caregiver report measure designed to provide a detailed assessment of temperament in children 3 to 7 years of age. In this study, two groups of participants were included to check cross validity. The first group of participants were 108 preschoolers, 3 to 7 years of age attending kindergartens or child care centers, and their mothers. The second group of participants were 168 preschoolers and their mothers. The CBQ subscales demonstrate adequate internal consistencies. Also, exploratory and confirmatory factor analyses of the CBQ scale reliably recover a three-factor solution indicating three broad dimension of temperament: extraversion/surgency, negative affectivity, and effortful control. Evidence for concurrent validity derives from results of correlation analysis with EAS scale.

This study begins with a review of commonly discussed dimensions of public risk perception that may influence public opinion toward risks. Factors that have been revealed by the literature to have substantial impact on risk perception, such as demographic background, trust, and media environment, are also discussed. Meanwhile, we evaluate two well-known research models in the realm of risk analysis: 1) the psychometric paradigm, and 2) the social amplification of risk framework (SARF). Based on a literature review, this study suggests that, besides the psychological and social approach, models of risk perception and risk communication research should shift to a more comprehensive one by considering the interrelations between laypeople and the environment. This study proposes a research model from the perspective of social cognitive theory (SCT) as a potential framework for future studies: 1) in the societal environment, individuals' risk perception and information seeking behavior, which is determined by risk perception will be influenced by trust in regulators and interpersonal trust; 2) in the media environment, individuals' risk perception and information seeking behavior will be influenced by individuals' perceived information characteristics. Knowledge about risk accumulated through information seeking will change risk perception in a longitudinal process.
