Purpose: The purpose of the study was to develop a knowledge scale of risk factors for fall among community-dwelling older adults. Further, the validity and reliability of the scale was developed. Methods: A preliminary scale was developed through content validity by five experts and targeted subjects using the CVI (Content Validity Index). Following the establishment of content validity, the scale was used with 359 community-dwelling older adults to further establish both validity and reliability of the scale. Specifically, construct validity using known-group comparison technique, and reliability using Cronbach's ${\alpha}$ were established. Results: After content validity testing, 44 preliminary items were selected. Construct validity was established by known group-comparison, in which scores between the fall and no fall groups were compared. The Cronbach's ${\alpha}$ of the final scale was .83. Conclusion: Reliability and validity of the scale were confirmed. This tool may be used for measuring knowledge of fall risk factor for the community-dwelling older adults.

Objective: Patellofemoral pain syndrome (PFPS) is a condition that is characterized by patellar discomfort or pain that is aggravated during certain activities such as ascending/descending stairs. The Patellofemoral Disability Index (PDI) was developed to assess the effect of pain on functional activities in individuals with PFPS. The objectives of the current study were to determine the internal consistency, test-retest reliability, and validity of this index. Design: Cross-sectional study. Methods: Forty-one subjects who had PFPS with a mean age of $28.8{\pm}5.0years$ and a mean body mass index of $25.6{\pm}4.7kg/m^2$ participated in the study. All subjects were concurrently enrolled in a clinical trial for which they were instructed to complete hamstring-resistance exercises for 4 weeks. Over the course of the intervention, they completed both the PDI and the Oswestry Disability Index (ODI) at baseline after two weeks, and after four weeks. Pearson correlation coefficient was used to assess the criterion validity. Cronbach's ${\alpha}$ was used to examine the internal consistency. Intraclass correlation coefficients with 95% confidence interval were computed to examine test-retest reliability. Results: Subjects' responses within both the PDI and the ODI yielded Pearson correlation coefficient values that were positive and highly significant (range, 0.73-0.97; p<0.001). There was a high level of internal consistency (Cronbach's ${\alpha}{\geq}0.8$), with the exception of stair climbing (Cronbach's ${\alpha}=0.65$). Intraclass correlation ranged from 0.87 to 0.92, indicating high levels of test-retest reliability. Conclusions: The PDI is a valid, reliable, and feasible method of assessing pain and functional ability in patients with PFPS.

Purpose: This study was to develop the Preventive Self-Management Knowledge related to Premature Labor (PSMK-PL) scale for women of childbearing age. Methods: Preliminary items were developed based on the literature and interview results of those who experienced premature labor. The online survey was conducted and the data of 250 women were analyzed using the DIMTEST and DETECT programs by applying the item response theory. Internal consistency reliability was analyzed with Cronbach's alpha (95% CI). Results: Among the 30 preliminary items, six items were deleted. The difficulty and discrimination of the 24 final three-dimensional scales were all acceptable, respectively. Cronbach's alpha (95% CI) was .89 (.87~.91). Conclusion: The PSMK-PL scale generally consisted of items with validity, and the reliability was acceptable.

The purpose of this study was to examine the validity and reliability of the Korean version of the nursing students' perception of instructor caring (NSPIC) scale developed by Wade and Kasper for nursing students. We collected data from 219 nursing students in the 3rd to 4th year at three nursing colleges from June 4 to June 20, 2018. Data were analyzed using SPSS 21.0 and AMOS 21.0. An exploratory factor analysis with varimax rotation was performed, resulting in five factors (respectful sharing, confidence through caring, control versus flexibility, supportive learning climate, appreciation of life's meanings) with a total of 27 items. Confirmatory factor analysis supported good convergent and discriminant validities. In addition, the concurrent validity test confirmed that the K-NSPIC scale was a validity tool as the correlation of the clinical learning environment (CLE) scale appeared as r=.64 (p<.001). The Cronbach's alpha coefficient of the K-NSPIC was .88, and Cronbach's alpha coefficient for each of the five factors was .91, .86, .80, .76, and .85; internal consistency was confirmed. It is significant that the K-NSPIC proved applicable as a useful tool for assessing instructor caring. It is also expected that it will assist in the design of programs to improve the caring ability of instructors.

Although Attention Deficit Hyperactivity Disorder(ADHD) has been considered as the disorder occurring during childhood, the prevalence is increasing among adolescents and adults. The prevalence rate varies from 2.0 to 14.3% due to the difference of diagnostic criteria, different assessment methods, or subjects' age difference. Therefore, it needs to make age specific(i.e., for children, for adolescents, and for adults) assessment tools. Authors translated Conners-Wells Adolescents Self-Report Scales(short form)[CASS(S)] in to Korean to get validity and reliability as a way of development of assessment tool for adolescent with ADHD in Korea. CASS(S) was translated and corrtected by three psychiatrists and one clinical psychologist. To examine the concurrent validity and test-retest validity, CASS(S) was applied with K-YSR on one class of each grade in a middle school in Seoul with two week interval(total 115：male 58, female 57). To test validity, authors analysed and got Cronbach's as internal consistency. Construct validity was done by principal axis factor analysis on 4,354 students. As a result, Cronbach's alpha for internal consistency was .88, Pearson coefficient for test-retest reliability .83, and coefficient for concurrent validity .65. And in the factor analysis to examine construct validity, three factors were revealed as cognition, hyperactivity, and conduct. These results shows that CASS(S) may be useful tool for adolescents with ADHD, although there was a limit not to be done the comparison with clinical groups.
