  • This study has a purpose of developing a scale to evaluate maternal beliefs on preschool children's education. The subjects were 307 mothers of preschool children in Gwang-ju. The methods for data analyses included a factor analysis for construct validity, Pearson correlations between beliefs and learning-related activities for construct validity, and Cronbach's a for reliability. 4 factors were found, through literature review, in parental beliefs: passive learning, active learning, instruction, and expectation for academic-related skills acquisition. Factor analysis revealed that the 4-factor solution is the best fit. Correlations between beliefs and learning-related activities were statistically significant. Cronbach's a ranged from .65 to .87 for 4 sub-scales. It was concluded that the maternal beliefs scale is acceptable for use.

  • The structure and dimensionality of the User Information Satisfaction (UIS) construct is an important theoretical issue that received considerable attentions. The acceptance of UIS as a standardized instrument requires confirmation that it explains and measures the user information satisfaction construct and its component. Based on a simple of 670 respondents who participated in dealing with the Public Management Information System (PMIS), this research used a confirmatory factor analysis to test the alternavtive models of underlying factor structure and assessed the reliability and validity of these factors and items in the PMIS. The result provided a support for a revised UIS model with four first-order factors and one PMIS The result provided a support for a revised UIS model with four first-order factors and one second-order (higher-order) factor in PMIS. To cross-validata these results, the author reexamined two prior data sets. The results showed that the revised model provides better model-data fit in all three data sets.

  • This study investigates the relationship between perceived system characteristics of Internet shopping mall and loyalty, and examines how perceived website attractiveness and flow play mediating roles between perceived system characteristics of Internet shopping mall and affective commitment in the context of Internet clothing shopping mall. For these purposes, the author developed a structural model which consists of several variables. In this model, perceived system characteristics of Internet shopping mall that consist of such as familiarity, reputation, uniqueness, positive emotion, self-efficacy, and interactivity were proposed to affect the website attractiveness and flow, and in turn, result in higher affective commitment. Thus, perceived website attractiveness and flow were proposed as core mediating variables between perceived mobile service characteristics and affective commitment. To test unidimensionality and nomological validity of the measures of each construct, the author employed scale refinement procedure. The results of reliability test with Cronbach's, and confirmatory factor analysis warranted unidimensionality of the measures for each construct. In addition, nomological validity of the measures was warranted from the result of correlation analysis.

  • Current studies validate the Body Positive Scale (BP Scale) as a self-assessment instrument that captures four dimensions of the positive body image construct. We developed and evaluated a 17-item BP Scale using two focus group interviews and four independent samples (n = 1,379) of Korean women who completed online survey questionnaires. We generated an initial pool of items via literature review, content validation with experts, and focus group interviews, subsequently refining the items through exploratory analysis (Study 1). We confirmed the BP Scale's underlying dimensions with young Korean female samples (Study 2, Study 4) and with a community sample (Study 3). We also examined the construct validity, internal consistency, and test-retest reliability over a six-week interval. Overall, the results supported that the four-factor BP Scale demonstrates adequate validity and reliability in measuring positive body image among Korean women. The BP Scale provides a method for researchers and practitioners to understand and assess individuals' positive body image in a multifaceted manner.

  • Purpose: The purpose of this study was to develop an instrument to assess bullying of nurses, and test the validity and reliability of the instrument. Methods: The initial thirty items of WPBN-TI were identified through a review of the literature on types bullying related to nursing and in-depth interviews with 14 nurses who experienced bullying at work. Sixteen items were developed through 2 content validity tests by 9 experts and 10 nurses. The final WPBN-TI instrument was evaluated by 458 nurses from five general hospitals in the Incheon metropolitan area. SPSS 18.0 program was used to assess the instrument based on internal consistency reliability, construct validity, and criterion validity. Results: WPBN-TI consisted of 16 items with three distinct factors (verbal and nonverbal bullying, work-related bullying, and external threats), which explained 60.3% of the total variance. The convergent validity and determinant validity for WPBN-TI were 100.0%, 89.7%, respectively. Known-groups validity of WPBN-TI was proven through the mean difference between subjective perception of bullying. The satisfied criterion validity for WPBN-TI was more than .70. The reliability of WPBN-TI was Cronbach's ${\alpha}$ of .91. Conclusions: WPBN-TI with high validity and reliability is suitable to determine types of bullying in nursing workplace.

  • Purpose: The purpose of this study was to develop and validate a hospice palliative care performance measure which would cover more than just physical symptoms or quality of life. Methods: Through an intensive literature review, the author chose questions that measured aspects of physical, emotional, spiritual, social, or practical domains pertinent to hospice palliative care for inclusion in the scale. Content validation of the questions was established by 15 hospice palliative care professionals. A preliminary Hospice Palliative Care Performance Scale (HPCPS) of 20 questions was administered to 134 pairs of terminal cancer patients from 5 hospice palliative care units and their main family caregiver. A validation study was conducted to evaluate construct validity and internal consistency. Results: Factor analysis showed 14 significant questions in five subscales; Physical, Emotional, Spiritual, Social, and Patient' rights. There were no significant differences between the ratings by patients and family members except for three out of the 14 questions. The measure demonstrated construct validity, and Cronbach's ${\alpha}$ of the subscales ranged from .73 to .79. Conclusion: The HPCOS demonstrated acceptable validity and reliability. It can be used to assess effectiveness of hospice palliative care for terminal cancer patients in practice and research.

  • The purpose of this study was to development of the 'convergence motive' scale for interdisciplinary knowledge fusion. Based on results from literature review, this study clarifies a theoretical ground for 'convergence motive'. Initial items to measure this concept were verified by content analysis and then finalized. After a pilot test done with 568 college students, gathered data were analyzed by item selection and exploratory factor analysis to verify their validity. Next, the main test implemented with 1,211 college students was analyzed with exploratory factor analysis using the method for rotation based on maximum likelihood analysis and direct oblimin for validating the final items to measure 'convergence motive'. As a result, the scale for 'convergence motive' consists of 43 items to measure the following four factors: collaboration to identifying and solving problems, challenge of a new perspective, communication for convergence, cohesion for convergence. Construct validity and criterion-related validity were performed at last to check this scale's theoretical construct. In conclusion, this study concluded that the scales for convergence motive could be generalized and applicable to other samples.

  • Purpose: This study was conducted to evaluate the validity and reliability of the Korean version of the Sexuality Attitudes and Beliefs Survey (SABS) and to assess SABS for Korean nurses. Methods: The Korean version of SABS was developed through forward-backward translation techniques. Internal consistency reliability and construct validity using confirmatory factor analysis were conducted using PASW+ PC Win (18.0) and AMOS (18.0). Data were collected from 567 nurses who worked in one of six general hospitals across the country. Results: The Korean version of SABS showed a reliable internal consistency with Cronbach's ${\alpha}$ of subscales ranging from .59 to .73. Factor loadings of the 10 items of three subscales ranged from .38 to .83. The three subscales model were validated by confirmatory factor analysis (GFI>.97, RMSEA<.05). Sexuality attitudes and beliefs for Korean nurses were more negative than that of European or American nurses. The SABS scores for Korean nurses were significantly different according to age, marriage, education, clinical experiences, and feeling about sexuality. Conclusion: The Korean version of SABS has satisfactory construct validity and reliability to measure Korean nurses' attitudes and belief toward sexuality. Education is essential to enhance importance and self-efficacy and to relieve barriers to addressing patients' sexuality.

  • Purpose: This study was aimed to construct an algorithm of dyspnea emergency care and develop a simulation scenario for emergency care of dyspnea based on the algorithm. Methods: The first stage of this methodological study was to construct a preliminary algorithm based on a literature review, and content and clinical validity were established. Reflecting the result of content and clinical validity for this preliminary algorithm, simulation scenario was developed based on the modified Bay Area Simulation Collaborative scenario template. The content validity of this scenario was established, and clinical applicability was tested by applying this scenario to nurses. Results: The final simulation scenario of emergency care of dyspnea consisted of scenario overview, curricular integrity, and scenario script. The scenario was proceeded on 7 phases of the algorithm as follows; initial assessment, immediate emergency care, reassessment of dyspnea, monitoring respiratory failure, checking pulse if respiratory failure occurs, decision making on cardiopulmonary resuscitation or intubation, determining a differential diagnosis according to origin of dyspnea. Conclusion: The simulation scenario of emergency care of dyspnea developed in this study may provide a strategy of simulation education for emergency care of dyspnea for nurses.
