SUMMARY
Introduction: This study aims for construct validation using
two approaches, i.e., exploratory factor analysis and Rasch
Model.
Methods: A cross sectional of 313 male workers from
multiple worksites had completed self-administered Malay
translated version of Three-Factor Eating QuestionnaireR21.
Data quality was assessed by misfit person criteria,
dimensionality, summary statistic, item measure and rating
(partial credit) scale followed by exploratory factor analysis
and internal consistency reliability assessment.
Results: The dual approaches of construct validation
analysis were complement to each other. Rasch analysis
supported the theoretical constructs of three eating
behaviour dimensions among respondents. In contrary to
exploratory factor analysis, it did show presence of a
newfound factor (α=0.04) came up from the separation of the
cognitive restrain and uncontrolled eating however, the
correlation between the two respective sub-factors were fair
(r=0.39) and weak (r= -0.08). Both analyses had detected
three problematic items but those items were
psychometrically fit for used for current study setting. The
data had adequate psychometric properties. Cronbach’s
alpha for cognitive restraint, uncontrolled eating and
emotional eating were 0.66, 0.79 and 0.87 respectively.
Rating scale quality was conformed to standard criteria.
Conclusion: Malay version TFEQ-R21 with promising
psychometric properties and valid measures for eating
behaviour dimensions among male workers aged between
20 to 60 years old is now available. Further development
should focus on the items in relation to Malaysian cultural
adaptation before its use for daily practice in future setting.

Korean Journal of Women Health Nursing 2017;23(4):221-232
PURPOSE: This study aimed to conduct a systematic review and to describe characteristics of the birth experience assessment instrument. METHODS: Literature related to the development of the birth experience assessment instrument was examined using a systematic review method. A literature search was conducted using the keywords as ‘[normal birth]; [satisfac* OR care quality]; [instrument OR scale] AND (development)’ through PubMed, CINAHL, SCOPUS, PsycINFO, and RISS. The search used quality appraisal through QUADAS (Quality Assessment of studies of Diagnostic Accuracy included Systemic reviews) yielding 17 records. RESULTS: The birth experience assessment instrument was categorized for instrumental characteristics: birth satisfaction (n=8), perception of labor experience (n=5), and birth care quality assessment in normal and operative birth experiences (n=4). Important key elements for content characteristics were as follows: nursing practice (n=10), pain control (n=5), environment (n=5), participation (n=4), and support (n=4). CONCLUSION: This study demonstrated that the birth experience instrument is appropriate for measuring quality of birth care in various clinical conditions. This review of the birth experience instrument reports that an appropriate psychometric tool for enhancing quality of birth care is important.

3.Reconsidering the Cut Score of Korean National Medical Licensing Examination.
Journal of Educational Evaluation for Health Professions 2007;4(1):1-
After briefly reviewing theories of standard setting we analyzed the problems of the current cut scores. Then, we reported the results of need assessment on the standard setting among medical educators and psychometricians. Analyses of the standard setting methods of developed countries were reported as well. Based on these findings, we suggested the Bookmark and the modified Angoff methods as alternative methods for setting standard. Possible problems and challenges were discussed when these methods were applied to the National Medical Licensing Examination.

PURPOSE: Since 2000, the Korea University Medical College has conducted Comprehensive Basic Medical Sciences Examination as a summative test. Summative assessment must be dependable in that it meets the highest standards of reliability and validity. The purpose of this study were to examine the validity and reliability of Comprehensive Basic Medical Sciences Examination and to improve the quality of the examination. METHODS: The subject of this study was the examination materials and scores of the test. We conducted exploratory factor analysis to testify validity. Cronbach alpha coefficient was used to examine the reliability. RESULTS: Only one factor was extracted from exploratory factor analysis. Its eigen value was 4.61 and it explained 65.93% of total variance. We could infer the extracted factor as an ability of basic medical sciences knowledge. The reliability coefficient of the test was ranged from 0.45 to 0.74. Of the total 335 item, overall acceptable items were 206(58.0%); the range of difficulty was 0.21~1.00 and discriminative indices were higher than 0.20. CONCLUSION: We confirmed the Comprehensive Basic Medical Sciences Examination in 2000 met the relative highest standards of reliability and validity. Item analysis could be of help to improve the quality of examination

5.Review of the Psychometric Evidence of the Perceived Stress Scale.
Asian Nursing Research 2012;6(4):121-127
PURPOSE: The purpose of this study was to review articles related to the psychometric properties of the Perceived Stress Scale (PSS). METHODS: Systematic literature searches of computerized databases were performed to identify articles on psychometric evaluation of the PSS. RESULTS: The search finally identified 19 articles. Internal consistency reliability, factorial validity, and hypothesis validity of the PSS were well reported. However, the test-retest reliability and criterion validity were relatively rarely evaluated. In general, the psychometric properties of the 10-item PSS were found to be superior to those of the 14-item PSS, while those of the 4-item scale fared the worst. The psychometric properties of the PSS have been evaluated empirically mostly using populations of college students or workers. CONCLUSION: Overall, the PSS is an easy-to-use questionnaire with established acceptable psychometric properties. However, future studies should evaluate these psychometric properties in greater depth, and validate the scale using diverse populations.

OBJECTIVE: The Positive and Negative Affect Schedule (PANAS) was developed as a measure of positive affect (PA) and negative affect (NA). The aim here is to examine the factor structure and concurrent validity of the Korean version of the Positive and Negative Affect Schedule (K-PANAS) in a clinical sample in Korea. METHODS: K-PANAS was administered to a clinical sample in Korea. Internal consistency, test-retest reliability, and confirmatory factor analysis (CFA) were undertaken to examine the factorial structure and reliability of the K-PANAS. RESULTS: The reliability of K-PANAS is satisfactory. CFA showed that several of the models commonly used in Western populations provided an insufficient fit. The modified model provided a more adequate fit to the data. CONCLUSION: The authors demonstrate that the K-PANAS has adequate psychometric properties, and that findings obtained in the West using PANAS were partially replicated.

7.What Do We See When We Look at Faces?.
Korean Journal of Orthodontics 2003;33(5):319-322
Recent scientific findings on the perception of facial attractiveness coupled with technological advances in computer imaging make it possible to measure the facial characteristics that may be associated with specific judgments of facial appearance. These new methods can be used to produce psychometric norms of facial attractiveness which potentially could supplement the conventional population norms or averages used currently in orthodontic treatment planning. It is hypothesized that consideration of psychometric norms will enhance doctor-patient communication and lead to greater patient satisfaction at the completion of orthodontic treatment.

Background: The learning climate has been found to be significant in determining students’ academic achievement and learning. The purpose of this study was to measure the viewpoints of nursing students toward their learning environment at Rafsanjan University of Medical Sciences (RUMS).
Methods: This descriptive, cross-sectional study was performed on 202 nursing students using the Dundee Ready Educational Environment Measure (DREEM). The items, as well as scale scores were compared among nursing students. Also, data was analysed by SPSS19 using t test and ANOVA.
Results: The total mean DREEM score was 114.3 (SD 20.6) out of 200 (corresponding to 57.15% of the maximum score), which was considered as more positive than negative. The subscale with the highest mean score was Students’ Perceptions of learning. Mean score of this subscale was 27.3/48 0 (SD 5.9) corresponding to 56.87% of the maximum score. The lowest mean score was for the Academic Self-perceptions 20.31/32 (SD 4.51) (53.44%), The total DREEM score for female students was significantly higher than for males (P = 0.01). The total scores of new entry students were significantly higher than the others (P = 0.01).
Conclusion: The school’s educational climate was generally perceived positively by students, but specific areas identified by students as needing improvement. It is essential for managers to make a greater effort to create an appropriate educational environment in order to provide and maintain high quality learning environments for students.

OBJECTIVE: The Revised Obsessive Intrusion Inventory (ROII) is a 52-item scale that evaluates obsessional intrusive thoughts. The aim of the present study was to validate a short, 20-item Korean version of the ROII (ROII-20). METHODS: Of the 1125 participants who completed the ROII-20, 895 participants completed the scale to examine the factor structure of the scale. A subgroup of these participants (n=53) completed the scale twice to determine test-retest reliability. To establish external validity, 230 participants completed the scale and other questionnaires. RESULTS: Exploratory factor analyses suggested a hierarchical model comprising two higher order factors of autogenous obsessions (resulting from aggressive thoughts and sexual thoughts) and reactive obsessions (resulting from thoughts about contamination, thoughts about accidents, and thoughts about dirt). Confirmatory factor analyses supported this model. The results indicated good internal consistency and test-retest reliability. External validity was supported by relationships with obsessive-compulsive symptoms and general distress. CONCLUSION: The ROII-20 presents good psychometric properties and may be considered as a promising instrument for measuring obsessional intrusions.
