Purpose: The purpose of this study was to develop a valid Adult Fall Assessment Scale Korean version (FAS-K) for inpatients in general hospitals in Korea. Methods: This a 14 item FAS-K was developed based on a review of national and international research and expert opinions in related field. Interrater reliability of FAS-K was analyzed using the ICC (Intraclass Correlation Coefficients). To examine the validity of FAS-K, a CVI (Content Validity Index), the Pearson correlation coefficients between FAS-K and two widely used scales, the Morse Fall Scale (MFS) and the Johns Hopkins Hospital Fall Risk Assessment Tool (JHFRAT), and the Mann-Whitney test were used. Results: The ICC was .958. The CVI ranged from .70 to 1.00. The FAS-K was significantly associated with the MFS (r=.74, p<.001) and with the JHFRAT (r=.87, p<.001), verifying the concurrent validity of FAS-K. As for the construct validity of FAS-K, significant differences between the fall and non-fall groups were found not only in the MFS (Z=-3.23, p=.001) but also in the FAS-K (Z=-3.10, p=.002). Conclusion: The findings indicate that the FAS-K is a reliable fall risk assessment tool with high validity.

Purpose: This study was conducted to develop and test a measurement of the suicidal protection(MSP) for high school students in Korea. Methods: Thirty-four preliminary items were initially developed based on literature review and focus group interviews. Those items were evaluated by experts for content validity with 31 items yielded. For testing validity and reliability of the measurement, data were collected from 330 high school students in Korea. Results: The item analysis selected 26 items. One item was deleted additionally through the primary exploratory factor analysis. The final exploratory factor analysis yielded 26 items in six factors such as fear of suicide, self-esteem, emotion regulation, support from others, support from family, and school life, explaining 66.6% of the total variance of the suicidal protection for high school students in Korea. Convergent validity and discriminant validity were supported by construct reliability, average variance extracted estimate, and standardized regression weight. MSP scores were positively associated with economic status, academic record and suicidal ideation. Also, criterion validity was supported through a significant correlation with the Reason for Living Inventory for Adolescent. The Cronbach's ${\alpha}$ reliability coefficient was .93 for the overall measurement and .72~.86 for the six factors. Conclusion: The results show that MSP may be valid and reliable for assessing suicidal protection of high school students.

Purpose: This study presents a translation, cultural adaptation, and psychometric evaluation of two instruments of the Fertility Awareness and Attitudes Towards Parenthood (FAAP) questionnaire (Conditions and Life changes) for use in South Korea. Methods: This methodological study included 166 university students for psychometric evaluation in the sixth step. The first five steps included forward translation, backward translation, committee review, assessment of content validity, and a pre-test. In the sixth step, psychometric properties, including internal consistency, construct validity, and criterion validity, were evaluated. Exploratory factor analysis and confirmatory factor analysis were conducted to identify the structure of the tool and to assess its validity. Results: The Korean version showed acceptable internal consistency. Cronbach's α was .73 for FAAP-Conditions and .83 for FAAP-Life changes. FAAP-Conditions showed a four-factor structure (social conditions, relationship with partner, external environment, and child-rearing support) and FAAP-Life changes had a two-factor structure (reward and burden). In the confirmatory analysis, CMIN/DF, TLI, IFI, SRMR, CFI, and RMSEA were satisfactory. Conclusion: This study provided preliminary evidence of the acceptability, reliability, and validity of the Korean version of the FAAP questionnaire in university students in South Korea. Nonetheless, further evaluation among Korean young adults is warranted to validate this instrument.

Objective: This study aimed to develop a parent play interaction observation scale (PPIOS-Toddler) and analyze it in terms of item discrimination, reliability, and validity. Methods: The subjects of the study were 97 toddlers and mothers. This scale consisted of three categories, six domains and 22 items on a 5-point scale. For the item discrimination of the observation scale, an independent standard t-test was conducted to analyze the significant difference in average between the upper and lower groups for each item. The reliability of the observation scale was calculated by Cronbach's α, the intra-item agreement, and the validity was examined through content validity, the correlation between subdomains and total scores, and official validity using PICCOLO. Results: In item discrimination analysis, all items exhibited differences between upper and lower groups. The overall internal agreement for the observation scale was 0.95, with factor-specific internal agreement ranging from 0.83 to 0.95. The observation scale demonstrated notable correlations between total scores and sub-factors (0.45 to 0.93) and significant correlations with PICCOLO total scores (0.66 to 0.86). Conclusion/Implications: The study successfully verified the item discrimination, reliability, and validity of the Parent Play Interaction Observation Scale (PPIOS-Toddler).

Purpose: This study aimed to develop a Hybrid Clinical Practicum Environment Scale for Nursing Students (HCPES-NS) and verify its validity and reliability. Methods: The HCPES-NS was constructed following the DeVellis guidelines. The initial items were written based on a literature review and individual in-depth interviews. Content validity was verified through an expert panel review. To confirm the validity and reliability of the scale, a survey was conducted with 449 nursing students enrolled in 12 nursing colleges. Data were analyzed using item analysis, exploratory factor analysis, confirmatory factor analysis, concurrent validity, and reliability tests. Results: Factor analysis showed that the HCPES-NS consists of 15 items on five subdomains: clinical site atmosphere, interpersonal relationship, alternative online practicum contents, provision of learning information, and clinical performance facilitation. A higher score indicated a more positive perception of the clinical practicum environment. The concurrent validity of the HCPES-NS was confirmed by its positive correlation with the Clinical Learning Environment Scale (r = .77). The Cronbach's α reliability of the HCPES-NS was .84. Conclusion: The HCPES-NS is both valid and reliable. This scale reflects the clinical practicum environment and includes an online practicum factor. It may be used effectively by faculty members and educators to evaluate nursing students' perceptions of clinical practicum environments.

Purpose: Selection-optimization-compensation (SOC) models have been proposed and applied to various populations to examine successful aging from a multidimensional perspective. This study aimed to develop a scale to measure SOC strategy among late middle-aged women (aged 50 to 64 years) and to test its validity and reliability. Methods: Preliminary items were developed through a literature review and interviews. Overall, 32 preliminary items were confirmed via two rounds of expert content validity analysis and a pilot survey. Data were collected from 299 late middle-aged women and analyzed using IBM SPSS/PC+ version 27.0. Construct validity, criterion validity, and reliability tests were conducted. Results: The SOC strategy scale, reflecting the characteristics of late middle-aged women and developed through exploratory factor analysis, comprised 19 items across four factors: goal-oriented selection, compensation for loss, outcome optimization, and ability-based optimization. The scale explained 66.9% of the variance in total factors, with a Cronbach's α of .95. Statistically significant correlations with the reference scale (r=.30, p<.001) were observed. Conclusion: The developed scale demonstrated high validity and reliability, thus representing a viable instrument for measuring SOC strategy among late middle-aged women. Using this scale to assess the use of SOC approaches in these women can improve our understanding of the aging process and help establish supportive programs for their aging journeys.
