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.

Few would disagree with the idea that product aesthetics can be a powerful design tool, because it is important strategic variable not only for design research but also for product design. Surprisingly, however, academic literatures in design field are relatively silent of empirical research on how product aesthetics may be assessed and how its influence measured on consumer response. This study explores the role of the aesthetic elements of product design in influencing consumer response. Specifically, The study reports a psychometric scale to measure consumer perceptions of the aesthetic dimensions of a specific class of product. (the perfume bottle) Although the present effort focused on perfume products, the role of aesthetics in the design of various product and packaging extends beyond the studied product categories.

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.

Purpose: The purpose of this study is to develop a nursing competence scale for soon to be graduate nursing students and to verify its validity and reliability. Methods: This study is a methodological study for development of a scale. Based on literature review and group discussion of 13 professional experts, 40 preliminary items were developed and the content validity was verified. Psychometric testing was performed and data were collected from 141 soon to be graduate nursing students of a university. Construct validity was verified by factor analysis and reliability was calculated. Results: The analyses resulted in a scale named the Nursing Competence Scale for Graduating Nursing Students (NCS-GNS), consisting of 30 items covering eight categories: nursing professionalism, integrated nursing through critical thinking, communication skills, nursing leadership, respect for life, stress management, nursing research, and core nursing skills. For the entire scale, the explained variance was 66.72% and Cronbach's alpha was 0.906. Conclusion: NCS-GNS was developed and its validity and reliability were verified. This scale can be used to evaluate nursing competence for graduating nursing students.

The purpose of this study was to examine the psychometric structure of Sasang typology with four personality measures and examine the construct validity of Sasang Personality Questionnaire (SPQ). We measured biopsychological traits of 104 university students using SPQ, Temperament and Character Inventory (TCI), NEO-Personality Inventory (NEO-PI) and Myers-Briggs Type Indicator (MBTI). The construct validity of SPQ was analyzed with TCI, NEO-PI and MBTI using Pearson's correlation. The temperament features of each Sasang groups were compared with Analysis of Variance and Profile Analysis. The SPQ showed significant correlation with TCI Novelty-Seeking (r=.398), TCI Harm-Avoidance (r=-.333), TCI Reward-Dependence (r=.465), TCI Self-Directedness (r=0.340), NEO-PI Extraversion (r=0.489) and MBTI Extraversion-Introversion (r=-0.509). The SPQ, TCI and NEO-PI revealed significant differences between Sasang constitutional groups. We examined the temperament construct of the Sasang typology and the validity of SPQ with well established western biopsychosocial instruments. This study would contribute to the objective studies on the biopsychosocial mechanism of Sasang medicine.

Translating expert knowledge into production rules has been the most difficult and time-consuming when building expert systems (Buchanan et al. 1983). Especially, buidling hierarchical structure, i. e. developing sequential or dominant relationship among production rules is one of the most important and difficult processes. Hierarchical relationship among rules has been typically determined in the course of interviewing human experts. Since this interviewing procedure is rather subjective, however, the hierarchically structured rules produced in terms of interviewing is widely exposed to the severe discussion about their validity (Nisbett and Wilson 1977 : Ericsson and Simon 1980 : Kellog 1982). We thus need an objective method to effectively translate human expert knowledge into structured rules. As such a method, this paper suggests the order anlaysis technique that has been studied in psychometries (Cliff 1977 : Reynolds 1981 : Wise 1983). In this paper we briefly introduce the order analysis and explain how it can be applied to building hierarchical structure of production rules. We also illustrate how bankrupcy prediction rules of small-medium companies can be developed using this order analysis technique. Further, we validata the effectiveness of these rules developed by the order analysis, in comparison with those built by other methods. The rules developed by the proposed outperform those of the other traditional methods in effectively screening the bankrupted firms.

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.
