This study attempted to develop a scale that Interpersonal Caring Behavior Measurement Tool, based on Kim's Interpersonal caring theory, and confirmed its reliability and validity. The items were used as 50 items of 10 concepts based on the Su-ji Kim's interpersonal care theory in Korea developed by Seon-hee Yun. Subjects were nurses working at a general hospital or higher, who agreed to participate in this study. As a result of the study, 50 questions in 10 concepts of the first were derived from active listening, accepting, complimenting, noticing, and companioning through exploratory and confirmatory factor analysis, and criterion validity and reliability were verified. This tool is meaningful in that it can measure Caring Behavior from the perspective of the subject and family, and can be used as an index to visualize the quality improvement of nursing care by quantifying it.

The purpose of this study was to analyse the qualitative and quantitative characteristics of paper-pencil tests for exploring its appropriateness as a selection tool of the gifted in science. For this purpose, we developed two (internal and external) item analysis frameworks, and applied these frameworks to analyse qualitative characteristics. Also, we analysed the relationship between two characteristics. The results of analysing qualitative characteristics revealed that the portion of items with acceleration context exceeding middle school curriculum level was relatively large, which caused low content validity. Furthermore, there was considerable deviation in content and context by subject matter and year, which caused test unstability. Items measuring knowledge domain was the most prevalent, and too much weight on data interpretation & analysis domain in inquiry process skills. In case of creativity test, the portion of items measuring convergent thinking was much larger than that of divergent or associative thinking. Most of these items were represented by using pictures and tables rather than using graphs. Item types of multiple-choice and short answers were superior to essay types. Discrimination index, on the whole, was appropriate (above 0.3), but item difficulty showed a vast deviation ($0.01{\sim}0.90$). Correlation coefficients among subject matters and test tools were very low, and test reliabilities were also low. Low item difficulty & high discrimination index item types were distinguishable. Items with acceleration context were more discriminating than enrichment context. Implications of developing quality paper-pencil test items in the selection of gifted students are discussed.

Objective : This study aimed to examine the psychometric properties of Korean version of Pediatric Volitional Questionnaire (PVQ-K) using classical test theory. Methods : For the translation of Pediatric Volitional Questionnaire (PVQ), as recommended in the literature, four-stage translation method was used. For the psychometric properties of Korean version of the Pediatric Volitional Questionnaire (PVQ-K), internal consistency reliability, content validity, and construct validity of the test using the known groups method and convergent and divergent methods were examined. For the recruitment of participants, a convenience sampling method is used. Participants of this study were 10 children with neuro-developmental disabilities hospitalized two different rehabilitations center and 10 children with typical development living in Daejeon, South Korea. All 20 participants were in aged from two to five years. Results : In terms of the content validity index, it was over 0.78, confirmed by nine experts of children development. PVQ-K successfully discriminated the scores of children with typical development from those with neurodevelopmental disabilities (p < .05). It is found that there is significant correlations between achievement stage of PVQ-K and the Korean Developmental Screening Test for Infants & Children (K-DTS)(.652 ~ .799 for subcategory, .706 for total scale). The internal consistency was .944 (Cronbach's ${\alpha}$). In qualitative content analysis, it was examined that how Korean children behave and respond in the environment, and how children's volition was strengthened or weakened by the environment. Conclusion : The results propose that PVQ-K can be a useful occupation-focused measure. This study recommend further study on PVQ-K with larger samples combined with the item-response theory approach.

The purpose of this study was to develop and validate the Korean version of the Classism Attitude Scale for college students (K-CAS) that measures stereotypes and prejudices about socioeconomic class(SES). In study 1, preliminary items were developed through reviewing classism related theories and literatures, analyzing qualitative data by using Consensus Qualitative Method-modified(CQR-M) and getting experts' consultation. With 440 college students data, exploratory factor analysis and reliability analysis were conducted with 14 items in study 1. In study 2, a confirmatory factor analysis and validity analysis were conducted with 400 college students. As a result, two factor structures, upper classism attitude and downward classism attitude, were confirmed. With the higher level of test-retest reliability, the criterion validity was confirmed by the significant correlations among age, subjective SES, the general belief in a just world, negative affects (depression and anxiety), hostility, and K-CAS. The incremental validity was also confirmed that K-CAS scores significantly accounted for 5% of total variation in scores of negative affects(depression and anxiety) in addition to the variables, such as age, subjective SES, house income, and the general belief in the just world. The result of this study is significant in that the developed and validated K-CAS in this study can be a useful tool for further research and prevention and intervention program development related to classism.

This study was aimed to construct a theoretical model for managing persons with early psychosis. We systematically searched SCOPUS, PubMed, RISS, Web of Knowledge, and KoreaMed for related factors to manage persons with early psychosis. Significant terms or phrases for a preliminary structural model were obtained from 19 studies since 2000 regarding the management of persons with early psychosis. Moreover, the content validity for the model was evaluated by 22 professionals. The study results revealed 51 factors for managing persons with early psychosis extracted by meta-analysis, and all factors were divided into 21 medium classification and 8 categories. A theoretical model was constructed with 8 categories, by using the middle range theory of Peplau's Interpersonal Relationships in Nursing. The results suggest that the theoretical model for the management of persons with early psychosis provides a sound theoretical basis for future study.

The aim of this study was to identify bibliographic characteristics and research trends of articles published on the elderly people in dental hygiene. An analysis was done of 191 articles published from 1999 to 2017. Bibliographic characteristics were nine items such as publication journal, research design, research participants, number of researchers, data analysis method, keywords, research topic, and validity and reliability report. The collected data were analyzed using descriptive statistics of statistical program. First, the research on the elderly, which was published in dental hygiene, started to be published in 1999 and on going. Though major publications have been published in Journal of Korean Society of Dental Hygiene and Journal of Dental Hygiene Science, the kinds of journals are becoming diverse. Second, cross-sectional research was the most. Third, the elderly were the most studied subjects, but the criteria varied. Fourth, the number of authors was largest in order of two and three person. Fifth, data analysis method was in order of descriptive statistics, t-test, and ANOVA. Sixth, there were many duplication of keywords about oral, elderly, and health. Seventh, oral health behavior science was the most studied subject. Eighth, validity and reliability were reported at 27.4% and 51.6%, respectively. Ninth, only 15.7% of study was founded research funding. Based on the results of this study, we consider increase experimental research further. Therefore, it is recommeded that validity and reliability should be reported in research paper, and the keywords used in the field of dental hygiene should be agreed upon.

Patients' evaluation of hospital care is one of the most important aspects of quality assessment. Survey allows patients to judge sujectively the events that occur during their hospital visit if performed properly. This study describes the result of a research effort to develop outpatient questionnaire that has sufficient validity and reliability to be used to measure patients' perception of satisfaction in Korea and to investigate influencing factors on patients' satisfaction. Self-administered questionnaire was developed for outpatient and the survey was conducted covering 827 outpatients in a tertiary hospital. It was confirmed by factor analysis that patients evaluate several components of ambulatory care distinctly ; hospital environment, administration and ancillary services, and medical care. We found strong evidence of construct validity and internal consistency for the above three dimensions of hospital process. On the contrary, reliability of overall outcome measures was low. It suggests that three items concerning overall outcome measures have some different meanings in patients' perception. Using logistic regression analysis it was found that previous health status, cost evaluation, and improvement in health status have significant influences on the level of patients' overall satisfaction and that patient's sex, experience of previous visit, expectation for improvement, cost evaluation, and improvement in health status are strongly related with intention to recommend hospital. In spite of some limitations the results of this study can be used helpfully as baseline informations for developing self-administered questionnaire and for exploring the influencing factors on patients' satisfaction. Further comprehensive research efforts should be made on the measurement of ambulatory patients' satisfaction and its related factors in current Korean situation.

This study attempts to develop the scale of 'Caregiving Affirmation Scale' for Korean Caregivers for the Aged and to testify the possibility of generalizing the scare. Mixed methods of qualitative and quantitative researches were used to achieve the purpose of the study. The steps of developing the scale were proceeded as follows: Firstly, 40 items were identified through the qualitative study and the literature reviews. Secondly, the content validity was verified through the professional group survey in addition to confirm the questionnaire items by the 1st survey. And thirdly, the construct validity and concurrent validity of the factors of 'Caregiving Satisfaction' were explored by performing the 2nd survey. As the results of the study, the total 16 items of 'Caregiving Affirmation scale' identified with the four sub-factors as follows; 1) Improvement of the care skill and a sense of fulfillment; 2) Possibility of contributions to other persons; 3) Acceptance of the aged; and 4) Improvement of Self-value. The reliability value of Cronbach's α was 0.89 with the high internal consistency and the confirmatory factor analysis showed the relationship between the items and each factor were also statistically significant. Thus, the content validity was verified. Also the correlation with the affirmative care recognition and the life satisfaction was 0.65, which meant the concurrent validity exists. The Caregiving Affirmation Scale for Korean Family Caregivers for the aged is expected to be used at the social welfare practice settings for the aged.
