Purpose: The purpose of this study was to develop and test the validity and reliability of the Korean version of the Contraceptive Self-efficacy (K-CSE) scale. Methods: The K-CSE scale was developed through forward-backward translation methods. Construct and criterion validity and internal consistency reliability were calculated using SPSS/WIN 21.0. Data were collected from 257 women students from two universities in G city, South Korea. Results: The factor structure of the K-CSE scale showed the cumulative variance as 62.9% in the factor analysis. Factor loading of 13 items on four subscales ranged from .47 to .88. Factors were named as 'initiative of contraceptive use', 'sexual assertiveness', 'refusal of sexual intercourse', and 'autonomic sexual behavior'. Criterion validity compared to the Sexual Autonomy Measurement (SAM) showed significant correlation. Cronbach's ${\alpha}$ for the reliability of each subscale were .50~.82 and .76 for the total scale. Conclusion: The findings of this study demonstrate that the K-CSE scale is a satisfactory valid and reliable scale. Therefore, the CSE scale can be useful in measuring contraceptive self-efficacy among women university students in Korea.

Objective: The purpose of this study is to find out the reliability and validity of the newly updated Balancia 2.5 program using Wii balance board through equipment that can measure center of pressure data with the precision. Design: Cross-sectional study Methods: Twenty-seven healthy adults participated in the study. The subjects were assessed for static balance ability by Accusway, and were assessed for static balance ability on Wii balance board connected to theBalancia 2.5 program.To limit postural fluctuations due to stare, the subjects were asked to look at a 15 cm dot drawn 3 m in front of them for 30 seconds with their eyes open. Static balance ability data such as path length and sway velocity were extracted from all measurement tools.Intra-rater and inter-rater reliability and validity were extracted through intraclass correlation coefficient (ICC) and 95% confidence interval (CI). Results: The intra-rater reliability that the same rater shows consistent results through test-retest was a high level at ICC=0.968 (0.926~0.986), and inter-rater reliability that the requires consistent results even when measured by different raters was a high level at ICC=0.943 (0.870~0.975). The validity was a high level at ICC=0.948 (0.881~0.977), which shows whether the measurement tool is properly measuring what it is intended to measure. Conclusions: The Balancia 2.5 program, newly updated through this study, proved to be a program with high reliability and validity in evaluating static balance ability like the existingBalancia 2.0 program.

The purpose of this study was to establish reliability and validity of the Northwick Park Neck Pain Questionnaire (NPQ) translated into Korean for neck pain patients. Sixty-two subjects (35 males, 27 females) with neck pain enrolled in the study. They completed a standardized self-administered questionnaire that included pain intensity, sleeping, sensory at night, duration of symptoms, carrying, reading and watching television, working, social activities, and driving. Reliability was determined by intraclass correlation coefficient (ICC) and Cronbach's alpha by internal consistency. Validity was examined by correlating the NPQ scores to the Visual Analog Scale (VAS) score. Test-retest reliability of the translated versions of the NPQ was good ICC(2,1)=.83 (95%CI=.85~.95). Cronbach's alpha value for NPQ was found to be .87 and this was statistically significant (p<.05). The criterion-related validity coefficients was .75 (p<.01). We concluded that the Korean version NPQ was shown to be a reliable and valid instrument for the assessment of neck pain.

Purpose : The purpose of this study was to establish intra-rater, inter-rater, test-retest reliability, and concurrent validity of figure-of-8 walk test in people with stroke. Methods : The subjects of this study were 17 patients who were diagnosed with a stroke. Subjects were tested twice by the same raters, with 1 day between tests. Subjects were assessed by two physical therapists. Test-retest reliability was calculated using intraclass correlation coefficients (ICC). The concurrent validity was demonstrated by spearman correlation of F8WT with 10m walking test (10MWT), timed up and go test (TUG), Berg balance scale (BBS), dynamic gait index (DGI) and four square step test (FSST). Results : Intra-rater, inter-rater, test- retest of F8WT time, showed high reliability. Intra-rater, inter-rater, test-retest of F8WT steps demonstrated high reliability. Intra-rater, inter-rater, test-retest of F8WT total smoothness score showed below moderate reliability. There was a significant positive correlation of F8WT time with 10MWT, TUG, FSST. There was a significant negative correlation of F8WT time with DGI, BBS. There was a significant positive correlation of F8WT steps with 10MWT, TUG, FSST. There was a significant negative correlation of F8WT steps with DGI. There was a significant positive correlation of F8WT test total smoothness score with BBS. Conclusion : The time, and number of steps in F8WT show high inter, intra-rater, test-retest reliability. The F8WT smoothness shows below moderate reliability. The F8WT shows high concurrent validity with other comparable balance, and walking tests. The F8WT is a valid and reliable measure for assessing walking function in patients with a stroke.

To evaluate body image disturbance in Korea, the Body Image Scale(BIS) was developed and it's reliability and validity was tested. The BIS was administered to 33 subjects of normal controls and 64 patients consisting of mainly neurotic patients. The correlation coefficient, of test-retest reliability with an interval of 2 weeks was 0.88 and internal consistency coefficient Cronbach's alpha, was 0.80. Discriminant validity test indicated that there were significant differences in total BIS score between normal control group and psychiatric patients group after controlling the effects of age, sex, and educational level. Factor analysis showed two distinct dimensions, namely 'physical appearance' and 'physical health and strength'. The BIS appears to be a reliable, internally consistent and valid scale which can be used for assessing body image in Korea pupulations.
