The aim of this study is to make the recall-based reading span test(Daneman & Carpenter, 1980) into the recognition-based test for on-line measuring the capacity of the participant. In order to measure the concurrent validity, a series of experiments is performed with varying features of distractors consisting of the reading span test. In experiment 1, which included irrelevant words as distractor, low correlation was observed. And in experiment 2, including several types of distractors which interfere with the selection of target words, low correlation was observed too. But in experiment 3, including distractors no more relevant in the Present trial but relevant in previous trial, high correlation was observed. The results of this study have theoretical implications on the validity of the reading span test and practical implication in that this study provides the tool for the studies on individual differences in working memory capacity.

This study was designed to develop a teacher's rating scale of elementary school student's school maladjustment. 50 behavior were drawn as elementary school student's school maladjustment behavior from the responses of elementary school teachers. To identify sub-factors of the scale, 60 teachers rated their 240 student's behavior and the collected data were analyzed by using factor analysis. 4 sub-factors were identified as the result : aggressive selfish behavior, misconduct of lesson and classroom rules, passive unsociable behavior and positive evasion of school activities. To identify the validity of the scale, the data from 120 students were analyzed through the concurrent validity between the scale and the teacher rating scale of school maladjustment for Student Problem Behavior Checklist for Elementary School students(Kim & Hwang, 2009). To examine the reliability of the scale, test-retest correlations were calculated by using the data from 120 students and internal consistency coefficients were calculated by using the data from 120 students. The results showed that Teacher's rating Scale of Elementary School Student's School Maladjustment was valid and reliable.

Purpose: The purpose of this study was the examination of the correlations between the daily physical pain intensity (DPPI) scale and the numeric rating scale (NRS), and between the DPPI scale and the quality of life (QOL) of short form health survey (SF-36) and beck depression inventory (BDI) questionnaires. The focus of the DPPI scale was the daily-living activities of the individual, and the scale contains three items regarding the pain per movement range, the pain per day, and the pain when touching the pain area. Methods: A total of 241 adults answered the DPPI, NRS, SF-36, and BDI questionnaires. Pearson's correlation coefficients were calculated for the various relations of the DPPI to the other scales. Results: High correlations were shown between the NRS and the DPPI (r=0.809, p<0.05). The DPPI scale (r=0.437, p<0.05) showed "moderate" significant correlations with the SF-36 and the NRS (r=0.370, p<0.05), and it showed "weak" significant correlations with the SF-36. There are no statistically significant correlations between the DPPI, the NRS score, and the BDI score (p>0.05). Conclusion: This study was the first attempt to establish the concurrent validity of a new focus on daily-living activities for the assessment of pain. This study showed promise for the development of activities of daily living focused tool for an assessment of the subjective pain in patients that was more objective.

Introduction The Sasang Urination Defecation Inventory was developed to analyze Sasang-type specific pathophysiological clinical symptoms, and its revised Sasang Urination Inventory (SUI) illustrated its clinical usefulness in Sasang type differentiation. However, the correlation with established clinical measures for its concurrent validity were not provided yet. Methods Total of 48 healthy university students were recruited to response Urogenital Distress Inventory-6 (UDI-6) and Overactive Bladder Symptom Score (OABSS) of Western medicine along with the SUI of traditional Korean medicine. The correlation coefficients between UDI-6 and OABSS and SUI were acquired with Pearson's correlation, and Analysis of Variance (ANOVA) and Profile Analysis were used to analyze significant differences in SUI subscale profiles of each Sasang types. Results The SUI-HSS of urogenital hypersensitivity correlated positively with OABSS (r=0.442, p<0.01), and the SUI-DIS of urinary discomfort positively with UDI-6 (r=0.289, p<0.05). Interestingly, the SUI-total was correlated positively with age (r=0.326), height (r=0.318) and weight (r=0.304). The SUI-DIS for urinary discomfort of So-Yang (9.48±2.11) type was significantly (p<0.05) higher than that of Tae-Eum (7.2±2.90) type. And SUI subscale profiles of each Sasang type were significantly (Wilks' Lambda=0.792, F=2.723, p=0.034) distinctive to each other. Discussion The acceptable convergent validity of SUI was shown using established measures of urogenital symptoms. The SUI might be used as an objective traditional Korean clinical measure for Sasang type differentiation and urological patients.

Objective: The purpose of this study was to analyze and compare vertical ground reaction forces during sit to stand (STS) and gait between female elderly and young individuals using the Wii Balance Board (WBB). Design: Cross-sectional study. Methods: Fifty-one female elderly people (age: $75.18{\pm}4.60years$), and 13 young people (age: $29.85{\pm}3.69years$) performed the five times STS test and gait respectively on the WBB. We analyzed time (s), vertical peak (%), integral summation (Int_SUM, %), and counter variables (%) in STS and 1st peak (body weight, BW%), 2nd peak (BW%), peak minimum (BW%), time (second), center of pressure (COP) path length (mm), and Int_SUM (BW%) in gait. The independent t-test was used to assess for differences in STS, gait ability, and general characteristics between the female elderly group and young adults group. With the first and last trials excluded, the mean value was obtained from the middle three of the five trials. Results: During STS, Int_SUM and time of young adults were significantly less than of the female elderly subjects. There were no significant differences in peak and counter variables. In gait, all variables (1st peak, 2nd peak, min, time, COP_path, and Int_SUM) showed significant differences between groups (p<0.05). This study demonstrated that the validity of vertical ground reaction forces occurring during STS and gait was significant in female elderly and young adults. Conclusions: Based on the measurement of vertical ground reaction forces in STS and gait using the WBB, it is possible to clinically improve the quality of geriatric physical therapy. Further studies are necessary to examine concurrent validity of elderly patients who have undergone total hip or knee replacement.

Purpose: This study reviewed screening and assessment tools that are used to measure delirium in patients with cancer in hospice and palliative care settings and examined their psychometric properties. Methods: Four databases were searched for studies using related search terms (delirium, tools, palliative care, cancer, and others). The inclusion criteria were a) studies that included screening/assessment tools for measuring delirium in cancer patients receiving hospice/palliative care, and b) studies published in English or Korean. The exclusion criteria were a) studies that were conducted in an intensive care setting, and b) case studies, qualitative studies, systematic reviews, or meta-analyses. Results: Out of the 81 studies identified, only 10 examined the psychometric properties of tools for measuring delirium, and 8 tools were ultimately identified. The psychometric properties of the Memorial Delirium Assessment Scale (MDAS) were the most frequently examined (n=5), and the MDAS showed good reliability, concurrent validity, and diagnostic accuracy. The Delirium Rating Scale had good reliability and diagnostic accuracy. The Delirium Rating Scale-Revised 98 also showed good reliability and structural validity, but its diagnostic performance was not examined in hospice/palliative care settings. The Nursing Delirium Screening Scale showed relatively low diagnostic accuracy. Conclusion: The MDAS showed evidence of being a valid assessment tool for assessing delirium in patients with cancer in palliative care. Few studies examined the diagnostic performance of delirium tools. Therefore, further studies are needed to examine the diagnostic performance of screening/assessment tools for the optimal detection of delirium in patients with cancer in hospice/palliative care.

The present study explored the major components of adaptive game behavior among adolescents in Korea. Based on relevant research and a pilot testing, an Adaptive Game Use Scale (AGUS) was developed and validated. A stratified sampling procedure was used to draw a representative sample, and a total of 600 male and female students from middle schools and high schools in various regions participated in the study. Factor analyses revealed 7 facets of adaptive game behavior, including experiencing vitality, expanding life experience, making good use of leisure time, experiencing flow, exercising control, experiencing self-esteem, maintaining and expanding social network. Internal consistency and temporal stability(4 weeks) of the scale were both high. A confirmatory factor analysis indicated that a 7-factor hierarchical model fits well with the data. Moreover, additional analyses suggested that AGUS and game addiction are conceptually distinct. Correlational analyses also indicated that AGUS has good discriminant validity and concurrent validity. Implications of the findings and future directions were discussed.

The purpose of this study was to develop an assessment scale for healthy aging of middle aged women. The data were collected from 385 middle aged women in two large cities in Korea. The development processes of the scale were followed: Development of preliminary items; Verification of content validity and reliability; Factor analysis and criterion validity of final items. Results: Factor analysis resulted in the creation of the final scale, which consisted of 38 items that were grouped into 9 factors: self achievement, physical change adaptation, psychological change adaptation, interpersonal relationships, menopausal symptom adaptation, economic stability, physical health, social support, social change adaptation. The explanatory variance was 64.03%. The reliability of the scale was Cronbach's ${\alpha}=.90$. Correlation of the scale with healthy aging and depression, established its construct and concurrent validity was r=-.69, p<.001. The scale was confirmed to have a relatively high validity and reliability. The findings of the study can be useful as a measurement to evaluate healthy aging of middle aged women. Future researches with the scale will be helpful for basic data for the program development to support healthy aging of middle aged women.

The purpose of this study was to validate Preschool Child Observation Record-II developed by High/Scope for Korean preschool children. The subjects of the study were 255 children aged three to six attending child care centers and their head teachers. They were observed for at least two months and completed the Korean version of Child Observation Record-II(K-COR-II). K-COR-II consisted of six categories and 32 items which had five-level-rubrics. The results from an exploratory factor analysis identified one dimension of the scale, there was no evidence of discriminant validity even after face validity was examined. The concurrent validity and internal consistency of the revised scale were relatively high. Also, the mean between the upper and lower groups with regard to item discrimination showed significant difference. It was concluded that K-COR-II can be used as a valid and reliable instrument to various aspects of preschool children's development.

In phase 1 of the study, data for the construct and items of KESAS(The Korean Elderly's Successful Aging Scale) were collected by indepth interviews with a purposive sampling group of 25 elderly people and focus group interviews with four groups. Content analysis was applied to the data and from this analysis were emerged six key categories of successful aging. In phase 2 of the study, 78 items were collected from the data of 2 sets of interviews mentioned above. Through pilot test, preliminary 66 items are selected. In phase 3 of the study, 597 cases collected from the survey were divided randomly into 345 developmental samples and 252 validity samples. The items were examined exploratorily with the developmental samples and confirmatorily factor analysis with validity samples. Confirmatory factor analysis supported the hypothesized six-factor structure of KESAS, which finally resulted in consisting of 31 items. Six factors are as follows: 'autonomous life', 'self-completion orientation', 'positive life participation', 'satisfaction with one's offsprings', 'self-acceptance', 'other-acceptance'. Cronbach's alpha estimate and split-half estimates of the scale were .903 and .845, which confirms that the scale has reliability. This six-factor model exhibited a good fit on the basis of the overall fit measure criteria(TLI=.983, RMSEA=.057) aquired by using the confirmatory factor analysis. Moreover, KESAS was significantly related highly(r=.72) to the 'Quality of Life for the Korean Elderly'. This proved concurrent validity of the scale.
