Purpose : his study was to analyze the reliability and validity on Oswestry Low Back Pain Disability Index (OLBPDI) in patients with low back pain. Methods : The sample consisted of 211 patients who had received treatments at the physical therapy units of 3 medical institutions from February to December 2008 in Andong city. Questionnaires on the OLBPDI were recruited by 6 physical therapists. The internal structure and reliability of the scales were evaluated by means of item-internal consistency(Cronbach's alpha coefficient:${\alpha}$), item-discriminant validity, Pearson's relation coefficient. Results : An average of patients's age was 41.1 years. The range of OLBPDI subscales were .93~.94 in Cronbach's ${\alpha}$. The internal consistency reliability of total item-each item were also internally consistent with Cronbach's ${\alpha}$ range of .94~.95(Pearson's correlation coefficient range: .62~.89). However, high correlation were obtained among 10 items(.67~.83), therefore the item-discriminant validity was a little low. Conclusion: In conclusion, the results reported here confirm the reliability of the OLBPDI scales in patients with low back pain. The collection of information on the level of disability due to low back pain using this instrument was acceptable to patients. A further prospective multi-center study will be necessary to prove the reliability and validity.

The purpose of this study is to provide the justification of the subject through review and alternatives example on the internal consistency of Home Economics curriculum components focused to the clothing & textiles area based on the beliefs and values inherent in the Home Economics curriculum. For this purpose, we examined the perspective of the assumptions about the five components of the curriculum - family, society, objective, subject matter, method in education - from the revised curriculum in 2007 to in 2015, and suggests an example of subject matter based on the result. The results of this study are summarized as follows. First, the clothing & textiles area of the revised curriculum from in 2007 to in 2015, family, society, objective, subject matter and method in education, excluding subject matter, were taken from a critical science perspective. In order for Home Economics curriculum components to be internally consistent, assumptions about the subject matter should be transformed to deal with the clothing & textiles as a family work. And needed to complement assumptions about family, objective and method in education. Second, based on the discussion, suggested an alternative example to the clothing & textiles area based on the internal consistency of Home Economics curriculum components.

Objectives : It was to translate three neck and spinal pain disability questionnaires - the Neck Disability Index (NDI), the Neck Pain and Disability Scale (NPDS), and the Functional Rating Index (FRI) - into Korean language, and evaluate the psychometric properties of Korean versions of questionnaires to achieve a good cross-cultural adaptation. Methods : Forty (23 males, 17 females) subjects aged from 15 to 64 years old, participated to examine test-retest reliability. One hundred and eighty (76 males, 104 females) subjects with a primary diagnosis of non-specific neck pain and 81 healthy volunteers were undertaken to examine internal consistemcy, discriminative validity and longitudinal construct validity. Versions of each questionnaire in idiomatic modern Korean were developed using a procedure proposed by Beaton et al. (2000). To assess reliability, the Intraclass Correlation Coefficient (ICC $_{(2,1)}$) was calculated. Internal consistency was evaluated by Cronbach's alpha. Discriminative validity was examined with independent-group t-tests. Responsiveness was tested by calculating the effect size and standardized response mean for each questionnaire and using Pearson' s r and the area under the receiver operating characteristic curve analysis. Results : Test-retest reliability ofthe translated versions of the three disability questionnaires was excellent (ICC $_{(2,1)$ = 0.86-0.90). High internal consistency was found in the three disability questionnaires (Cronbach's alpha ranged from ${\alpha}=0.88$ for the FRI to ${\alpha}=0.96$ for the NPDS and 0.82 for the Short Form McGill Pain Questionnaire(SFMPQ)). the VAS subscale of the SFMPQ was found to be the most responsive of the subscales (ES=1.44, SRM=1.37). The VAS was also the most responsive pain and disability index in internal responsiveness analysis, although disability indices showed marginally better responsiveness when compared with external standards. No floor or ceiling effects were observed. Conclusions : It is concluded that the questionnaires were successfully translated and exhibit acceptable measurement properties, and may suggest that they are suitable for use in clinical and research application.

Objectives : These days, herbal acupuncture therapy is widely applied to many diseases and symptoms by Korean medical doctors in Korea. The aim of this study was to demonstrate the effect of Carthami-Semen herbal acupuncture(CSHA) on chronic constipation. Methods : This single-blind placebo-controlled randomized parellel study enrolled 24 adults with chronic constipation. After one week's run-in period, they were randomly assigned to receive CSHA therapy, or placebo therapy for 4 weeks by 2 times per week. After completing 4 week's therapy, 2 week's follow-up period was continued. During study, defecation frequency, consistency and ease of evacuation were checked before study, every week and follow-up periods. Also, the VAS of constipation, quality of life(QoL) and heart rate variability(HRV : low frequency, high frequency) were checked 3 times totally. Finally, 21 subjects completed the protocol and 20 subjects were analyzed.(1 subject is excluded for analysis because of not following the protocol.) Results : In CSHA group, defecation frequency(continued after 1 week), consistency and ease of evacuation(at 1 week after and follow-up) were increased significantly. The VAS of constipation in CSHA group was significantly decreased. There was no significant change at QoL and HRV. Conclusions : CSHA therapy was effective in treating adults with chronic constipation. Study that have larger case number and longer follow up will be needed in the future.

The purpose of the study was to develop the parenting style scale which is reflecting cultural background of Korean parent's parenting for their children. The instalment was designed based on the literature reviews and on the Baumrind's parenting style. A total of three hundred and sixty two mothers whose children from first and second grade in elementary school completed the Questionnaires. The questionnaires consisted with the items addressing different types of parenting style which include love and care, encouragement of independence, enjoyment in parenting, communication, control, control of aggressiveness, strategies of control , request of maturity. Factor of analysis was applied to examine validity of Korean parenting style scale. Based on the factor analysis, 33 items selected for final questionnaire and two factors discovered. The first factor which named 'warmth'included 20 items such as love and care toward their children, communication, enjoyment in parenting, encouragement toward independency. The second factor which named'control'included 13 items such as control of children's behavior and discipline of children. Warmth factor accounted for 46% of variance and control factor accounted for 18% of variance. Internal consistency was also checked. Although warmth and control factor represented a moderate internal consistency, control factor showed lower correlations then warmth factor. The reliability estimates (Cronbach alpha) were. 87 and 71 for warmth and control factor respectively. Korean parenting style scale can be used to address the appropriateness of Baumrind's theoretical assumptions in parenting style as well as to examine parenting style for Korean population. However, this instalment was developed with Korean mothers only. Further analysis need to be addressed with fathers.

Purpose: To investigate the validity and reliability of the Korean Version of the Assault Response Questionnaire (ARQ-K) measuring the intensity of reaction to victimization of emergency nurses in Korea. Methods: An internal consistency reliability and construct validity using exploratory and confirmatory factor analysis were conducted using SPSS WIN (20.0) and AMOS (20.0). Survey data were collected from 321 nurses who worked in 3 levels - wide regional emergency centers, regional emergency centers, appointed emergency centers - of emergency care facilities in Busan, Korea. Results: The Cronbach's alpha values regarding internal consistency were .77~.93 for the subscales of ARQ-K. Factor loadings of the 26 items on the four subscales ranged from .59 to .84. The four-subscale model was validated by confirmatory factor analysis (${\chi}^2/df=3.85$, p<.001, RMR=.06, GFI=.80, NFI=.81, TLI=.83, CFI=.85, RMSEA=.09). Conclusion: This study shows that the Korean Version of the Assault Response Questionnaire is a valid and reliable instrument to assess nurses' reaction to victimization of emergency nurses in Korea.

Purpose: The purpose of this study was to evaluate the psychometric properties of the Korean version of the Alzheimer's Disease Knowledge Scale (ADKS-K) to determine its applicability to Korean adults. Methods: Cross-cultural validity was performed according to Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN). The Kuder-Richardson Formula 20 for internal consistency and Intraclass Correlation Coefficient (ICC) for test-retest reliability were conducted. Content validity, criterion related validity and construct validity were evaluated. The Classical Test Theory (CTT) model and the Item Response Theory (IRT) model were applied in performing the item analysis. Results: The KR 20 was .71, and the ICC was .90, indicating that the ADKS-K has internal consistency and stability reliability. Thirty items of the ADKS-K had significant Content Validity Ratio (CVR) values, i.e., mean of 0.82 and range of 0.60~1.00. Mean item difficulty and discrimination indices calculated by TestAn program were 0.63 and 0.23, respectively. Mean item difficulty and discrimination indices calculated by BayesiAn program were -0.60 and 0.77, respectively. These tests indicate that ADKS-K has an acceptable level of difficulty and discriminating efficiency. Conclusion: Results suggest that ADKS-K has the potential to be a proper instrument for assessing AD knowledge in Korean adults.

Purpose: The purpose of this study was to report the instrument modification and validation processes to make existing health belief model scales culturally appropriate for Korean Americans (KAs) regarding colorectal cancer (CRC) screening utilization. Methods: Instrument translation, individual interviews using cognitive interviewing, and expert reviews were conducted during the instrument modification phase, and a pilot test and a cross-sectional survey were conducted during the instrument validation phase. Data analyses of the cross-sectional survey included internal consistency and construct validity using exploratory and confirmatory factor analysis. Results: The main issues identified during the instrument modification phase were (a) cultural and linguistic translation issues and (b) newly developed items reflecting Korean cultural barriers. Cross-sectional survey analyses during the instrument validation phase revealed that all scales demonstrate good internal consistency reliability (Cronbach's alpha=.72~.88). Exploratory factor analysis showed that susceptibility and severity loaded on the same factor, which may indicate a threat variable. Items with low factor loadings in the confirmatory factor analysis may relate to (a) lack of knowledge about fecal occult blood testing and (b) multiple dimensions of the subscales. Conclusion: Methodological, sequential processes of instrument modification and validation, including translation, individual interviews, expert reviews, pilot testing and a cross-sectional survey, were provided in this study. The findings indicate that existing instruments need to be examined for CRC screening research involving KAs.
