The Body Appreciation Scale-2 (BAS-2) measures the extent to which individuals feel, accept, and respond to their own bodies in a positive manner. Given the research need to explore positive body image and its associations with various sociocultural factors and related consequences among individuals with various cultural backgrounds, several studies have established the psychometric properties and factor structures of the BAS-2 in different languages and samples with different characteristics. The current study investigated the psychometric properties and measurement invariance of a Korean version of the BAS-2 in an older Korean adult population (599 older Korean adults with the average age of 70 years). Data were collected using both online and offline (paper-based) survey questionnaires. The results of exploratory factor analyses and confirmatory factor analysis evidenced the unidimensional factor structure and measurement invariance of the Korean BAS-2 among older Korean men and women, after dropping item 1. Scalar invariance was supported across gender, and men and women did not significantly differ in observed mean scores of the Korean BAS-2. The results also supported good convergent validity and criterion validity. Incremental validity was demonstrated by predicting self-esteem over and above measures of age, BMI, subjective financial and health status, body esteem, and ageism. High internal reliability and test-retest reliability over a 2-week period were confirmed. Overall, the results of this study support the reliable use of a Korean BAS-2 to measure positive body image among older Koreans after excluding item 1.

Background: Trunk movements are an important factor in activities of daily living; however, these movements can be impaired by stroke. It is difficult to quantify and measure the active range of motion (AROM) of the trunk in patients with stroke. Objects: To determine the reliability and validity of measurements using a digital goniometer (DG) and smart phone (SP) applications for trunk rotation and lateral flexion in stroke patients. Methods: This is an observational study, in which twenty participants were clinically diagnosed with stroke. Trunk rotation and lateral flexion AROM were assessed using the DG and SP applications (Compass and Clinometer). Intrarater reliability was determined using intraclass correlation coefficients (ICCs) with 95% confidence intervals. Pearson correlation coefficient was used to determine the validity of the DG and SP in AROM measurement. The level of agreement between the two instruments was shown by Bland-Altman plot and 95% limit of agreement (LoA) was calculated. Results: The intrarater reliability (rotation with DG: 0.96-0.98, SP: 0.98; lateral flexion with DG: 0.97-0.98, SP: 0.96) was excellent. A strong and significant correlation was found between DG and SP (rotation hemiplegic side: r = 0.95; non-hemiplegic side: r = 0.90; lateral flexion hemiplegic side: r = 0.88; non-hemiplegic side: r = 0.78). The level of agreement between the two instruments was rotation (hemiplegic side: 23.02° [LoA 17.41°, -5.61°]; non-hemiplegic side: 31.68° [LoA 23.87°, -7.81°]) and lateral flexion (hemiplegic side: 20.94° [LoA 17.48°, -3.46°]; non-hemiplegic side: 27.12° [LoA 18.44°, -8.68°]). Conclusion: Both DG and SP applications can be used as reliable methods for measuring trunk rotation and lateral flexion in patients with stroke. Although, considering the level of clinical agreement, DG and SP could not be used interchangeably for measurements.

This study was performed to test the validity and reliability of the Health Self-Determinism Index for Children(HSDI-C), an instrument designed to measure dimensions and strength of motivation in health behavior, to improve the applicability of the tool through application to the various samples. The convenient sample of 148 (boys=75, girls=72 third grade=42, fourth grade=22, fifth grade=32, sixth grade=52 : Caucasian=72, Asian=30, African=19) comprised the children at a chatholic elementary school in Chicago. The children completed English version of HSDI-C from December 5th, 1994 to January l0th, 1995. The findings were as follows : 1. Four factors of HSDI-C were isolated through the principal component analysis and oblique rotation, and explained 48% of the variance in total score. Low correlations among four factors were anticipated because each factor contributed uniquely, All items of the tool loaded above .30 on one of 4 factors. But items loaded on each factor in this study were very different from those in the previous studies. 2. Cronbach's alpha coefficient for internal consistency was .81 for the total items and .57∼ .81 for 4 subscales. 3. The differences of HSDI-c mean scores between boys and girls and that of among races were not statistically signifcant, but the mean score of girls and the Caucasian were relatively high. The total mean score of the scale was highest at the 3rd grade, decreased at the 4th or 5th grade, and reincreased at the 6th grade. The trend of mean score of four subscales was similar to that of total mean score. According to the results, suggested below : 1. The items loaded on each factor in this study were very different from those in the previous studies. To clear away the problem of the conceptual confusion, HSDI-C needs to be performed to various and large samples. 2. Unexpectedly, the HSDI-C mean score decreased at middle school age. A longitudinal study will be helpful to search for the change trend of the intrinsic motivation. 3. To improve the applicabilty of the HSDI-C, various reliability and validity test methods besides factor analysis or internal consistency are recommended.

The WeeFIM is an outcome measure used worldwide to evaluate the functional abilities of children. The aim of this study was to evaluate the psychometric properties of WeeFIM in Korean children with cerebral palsy (CP) using the Rasch model. The mean age of the participants (92 boys and 53 girls) was 10.6 years (SD=2.3, range 5~15 years). The Winsteps software was used for analyzing the internal construct validity and reliability of WeeFIM. For analyzing the internal validity the motor and cognitive area items of the WeeFIM were analyzed both together and separately. When all 18 items were analyzed 4 were considered to be misfits; upper extremity dressing, lower extremity dressing, toileting, and comprehension. When only the 13 motor items were analyzed, toileting, bladder management, and bowel management were considered misfits. In addition, only comprehension was considered as a misfit among the 5 cognitive items. The most difficult motor items were stair climbing, and bathing. The simple ones were eating, bowel management, and bladder management. The most difficult cognitive item was problem solving, and the simplest one was comprehension. The person separation indexes and reliability for combined and divided instruments were reported as excellent. These results demonstrated the applicability of WeeFIM to Korean CP children with satisfactory reliability and validity. Further studies should include young children with CP and compare item difficulty among the different types of CP. In addition, the Korean normative data of nondisabled children should be used to compare the cultural differences between Korea and other countries.

Purpose: The purpose of this study was to develop a Korean nursing work environment scale for critical care nurses (KNWES-CCN) and verify its validity and reliability. Methods: A total of 46 preliminary items were selected using content validity analysis of experts on 64 candidate items derived through literature reviews and in-depth interviews with critical care nurses. 535 critical care nurses from 21 hospitals responded to the preliminary questionnaire from February to March 2021. The collected data were analysed using construct, convergent and discriminant validities, and internal consistency and test-retest reliability. Results: The 23 items in 4 factors accounted for 55.6% of the total variance were identified through item analysis and exploratory factor analysis (EFA). EFA was performed with maximum likelihood method including direct oblimin method. In the confirmatory factor analysis, KNWES-CCN consisted of 21 items in 4 factors by deleting the items that were not meet the condition that the factor loading over .50 or the squared multiple correlation over .30. This model was considered to be suitable because it satisfied the fit index and acceptable criteria of the model [𝒳²=440.47 (p<.001), CMIN/DF=2.41, GFI=.86, SRMR=.06, RMSEA=.07, TLI=.90, CFI=.91]. The item total correlation values ranged form .32 to .73 and its internal consistency was Cronbach's α=.92. The reliability of the test-retest correlation coefficient was .72 and the intra-class correlation coefficient was .83. Conclusion: The KNWES-CCN showed good validity and reliability. Therefore, it is expected that the use of this scale would measure and improve nursing work environment for critical care nurses in Korea.

Objectives : The aim of this study was to develop an assessment tool for measurement of children's functioning in the mental health service. We conducted a preliminary study to develop a sensitive and inclusive scale focused on the functional changes of children rather than just focusing on their symptoms or screening. Methods : The Child and Adolescent Functional Assessment Scale and the Korean-Child Behavior Checklist (K-CBCL) were both administered to 134 parents of children with emotional or behavioral problems who participated in the Aizone program and also to 186 parents of elementary school children in the Seoul metropolitan area as a control group. SPSS version 12.0 was used for statistical analysis. Results : Most of the reliability coefficients were over 0.70 except those of the conduct behavior items, which showed relatively high internal consistency. The corrected item-total correlations ranged from .411 to 758, except those of conduct behavior items and special measure items. In a concurrent validity test with K-CBCL, the total behavior problem score of K-CBCL was highly correlated with the total score of the Child and Adolescent Functional Assesment Scale (r=.610). For the construct validity, confirmatory factor analysis was performed for each of four areas, including behavior (at home/school), achievement, peer relationship, and emotion. Conclusion : The results showed that the scale was statistically reliable and valid, except for conduct behavior items. This study was conducted only for parents with elementary children. An adolescents group should be included in future studies.

This study was done to develop a eating behavior scale for high school girls using Stunkard and Messick(1985)'s three factors(dietary restraint disinhibition, hunger) as a conceptual framework and to test the validity and reliability of the scale. The subjects were 202 high school girls. The convenience sample is consist of 96 normal weight and 106 obese girls. Data were collected between October 28 and November 25 in 1996 and analyzed using the SPSS package. The new 32-item scale measuring these factors is presented 1. Three stable factors emerged and these contributed 45.7% of the variance in the total score. All 32 items loaded above .35 on each factor, 2. Factor 1 was named disinhibition(14 items), factor 2 was named cognitive restraint of eating(10 items), factor 3 was named hunger(8 items). Comparison of factor Ⅰ, factor Ⅱ, factor Ⅲ between normal subjects and obese subjects showed that there was a significant difference in factor Ⅱ & Ⅲ, not in factor Ⅰ. 3. Cronbach's alpha coefficient for internal consistancy was .9393 for total 32 items and .8820, .8652, .8490 for three dimensions of eating behavior in high school girls. Recommendations are suggested below : 1. Replication study with appropriate age groups be done to test validity and reliability, 2. The present developed scale must be a reliable measure of eating behavior and should have utility in further study on how effective nursing intervention related to different kind of groups such as disinhibition group and cognitive restraint of eating group. 3. To extend validity of the scale, further study is needs using more larger subjects which is consists of dieters and free eaters.

Objective : Existing depression rating scales do not fully reflect depressed patients' perspective of remission, which goes beyond symptom resolution. The Remission from Depression Questionnaire (RDQ) captures a broader array of domains, and the present study examines the reliability and validity of the Korean Version of the RDQ (K-RDQ). Methods : The test-retest reliability of the K-RDQ was studied in 60 depressed patients and 30 normal subjects working at a university hospital. Subjects were evaluated at baseline and again 1-2 weeks later. The validity of the K-RDQ was studied in 200 depressed patients who were rated on the 17-item HDRS and the CGI-S ; each patient also completed the QIDS-SR, STAI-S, GHQ/QL-12, and SDS. Results : The K-RDQ demonstrated excellent internal consistency, with a Cronbach's ${\alpha}$ of 0.965 for the total scale and above 0.80 for each of the 7 subscales. The test-retest reliability of the total scale was 0.951. Mean K-RDQ scores ($45.79{\pm}18.65$) of the depressed patients were significantly higher than those ($15.87{\pm}10.60$) of the mentally healthy subjects (t=12.8, p<0.001). Five factors from the K-RDQ were extracted by principal axis factoring with equimax rotation. Conclusion : These results indicate that the K-RDQ is a reliable and valid measure that evaluates multiple domains that depressed patients consider important in determining remission. Thus, the K-RDQ maybe considered an appropriate tool for use in the clinical setting.

Purpose: This study evaluated the internal structure (structural validity, internal consistency, and measurement invariance) of the Health-Related Quality of Life Instrument with Eight Items (HINT-8), developed to measure Korean people's health-related quality of life. Methods: A secondary analysis was conducted using data from the Korea National Health and Nutrition Examination Survey, involving 6,167 adults aged over 18 years. The structural validity of the HINT-8 was assessed using exploratory graph analysis and confirmatory factor analysis. Internal consistency and measurement invariance were analyzed using McDonald's omega (ω) and multigroup confirmatory factor analysis, respectively. Results: The HINT-8 had a single dimension and good internal consistency (ω =.804). The one-dimension HINT-8 exhibited matric invariance but not scalar invariance across sociodemographic groups (sex, age, education, and marital status). Further, it exhibited scalar or partial scalar invariance across medical condition groups (hypertension, diabetes, depressive symptoms, and cancer). Conclusion: The study finds that the HINT-8 demonstrated satisfactory structural validity and internal consistency, indicating its suitability for practice and research. However, the HINT-8 scores cannot be compared across different groups regarding sex, age, education, and marital status, as the interpretation varies within each sociodemographic category. Conversely, interpretation of the HINT-8 is consistent for individuals with and without hypertension, diabetes, depressive symptom, and cancer.

The purpose of this study were to factor analyze the 25-item Personal Resource Question-naire (PRQ)-Part II, a social support measure, and to establish construct validity for the instrument among adolescents by relationship found between perceived social support and the theoretically relevant variables of attachment, parent-child relationships, and coping, The sample was consisted of 451 college students, aged 18 to 24. According to the criteria used in this study a four-factor structure, which consisted of 15-items, resulting from a principal components analysis with an oblique rotation, best represented the multidimensionality of the PRQ-Part II of late adolescents in Korea. Evidence in support of construct validity for both the 15-item and 25-item PRQPart II was provided by statistically significant correlations found between the two scales and the theoretically relevant variable of attachment, parent-child relationships, and coping. With the findings of this study, the 15-item Korean version of the PRQ-Part II can be used in research and practice as a reliable and valid instrument measuring perceived social support for late adolescents in Korea.
