This study aims to determine the normative values of the Developmental Test of Visual Perception (DTVP-2) in Thai Children. The data was obtained from a sample of 1,120 children, and scoring followed. The DTVP-2 (Thai version) had been examined for validity and reliability. These studies showed that the DTVP-2 (Thai version) has acceptable content validity. The Index of Conjugate (IOC) was established by three reviewers: the IOC is 0.6 in sub-tests 1, 4, 5, 6, and 8;and the IOC is 1 in sub-tests 2, 3, and 7.Byusing a test–retest method, it wasfound that this test has a degree of reliability that is almost perfect. The entire DTVP-2 test has an Intraclass Correlation Coefficiency(ICC) of 0.89, and the ICC sub-tests range from 0.81 - 0.96.1
The aim of this study was to find out if there is a relationship between one's racial worldview, ethnic history, or cultural background and performance on visual-motor perceptual measures. The study also explored whether a newly developed visual-motor perceptual measure, the Oshodi Visual Motor Optimal Test (OVMOT), would serve as a parallel measure to existing Euro-American based visual-motor perceptual measures, the Bender-Gestalt Visual-Motor test in particular. A sample of 90 participants, African-American, Nigerian, and white Americans, participated in the study. Two visual-motor perceptual tests were used, the Bender-Gestalt Visual Motor test and the Oshodi Visual Motor Optimal Test (OVMOT). The study results revealed that there was generally a significant effect of cultural, ethnic, and epistemological worldviews on perception. Also the OVMOT was seen as significant in emotional and personality functioning. The study result was discussed according to the relevant literature research outcomes and a number of recommendations were suggested.
Guideline Development for the Evaluation of Visual Impairment in Korea
Journal of Korean Medical Science, 2009
This guideline is developed to provide criteria for evaluating permanent impairment of the visual system as it affects an individual's ability to perform activities of daily living. This new assessment system is based on the 5th and 6th edition of American Medical Association and McBride impairment assessment system but revised on the consideration of Korean culture and simple application. This evaluation of impairment is based on an assessment of visual acuity and visual field. Especially it weighs binocular vision and binocular visual fields and the binocular vision and binocular visual fields provide 50% of weight and the right and left eye each contribute 25%. A further adjustment of the impairment rating is included at the final step of this evaluation. Functional deficits for individual adjustments include diplopia, problem of accommodation, abnormality of eyelids, tearing, cosmetic problems from cornea opacity, glare, aphakia, and dark-adaptation. The adjustment can be added to impairment rating up to 15%. Further study is necessary to revise and update of this disability evaluation that have potential problems in actual application.
Assessment of psychometric properties of the Korean SF-12 v2 in the general population
BMC Public Health, 2014
Background: The psychometric properties of the Korean Short Form-12 Health Survey, version 2 (SF-12 v2) have not been assessed in the general population. Therefore, the aim of our study was to evaluate the psychometric properties of the Korean version of the SF-12 v2 in the general population and to provide SF-12 v2 domain scores according to the general characteristics of the study population. Methods: A total of 1,000 participants from the general Korean population were recruited using a multistage quota sampling method. Psychometric properties were evaluated by descriptive statistics, validity, reliability, and exploratory factor analysis. Results: Item convergent and discriminant validity met the criteria established by the instrument developer. In the known-group comparison, male gender, age <60 years, high educational status, and absence of any comorbidity were significantly associated with high scale scores. The reliability of all SF-12 v2 items was 0.88. Conclusions: The findings of this study generally support the idea that the Korean SF-12 v2 is a feasible, valid, and reliable instrument for assessing health-related quality of life in the general population. The SF-12 v2 seems to be a viable alternative health-related quality of life instrument for the Korean population.
Reliability and Validity of the Korean Child Sensory Profile–2
The American Journal of Occupational Therapy
Importance: The Korean Child Sensory Profile–2 (K-CSP–2) is a tool for assessing sensory processing that was recently culturally adapted for use with Korean children. Objective: To investigate the test–retest and interrater reliability and the convergent and discriminant validity of the K-CSP–2. Design: Cross-sectional study. Setting: Community settings in South Korea. Participants: Caregivers of 102 children with autism spectrum disorder (ASD) and 156 typically developing (TD) children ages 3–14 yr. Outcomes and Measures: The K-CSP–2 was tested for reliability and validity using the Korean version of the Sensory Profile (K-SP) and the Korean Behavior Assessment System for Children–2 (K-BASC–2). Results: The K-CSP–2 demonstrated good test–retest and interrater reliability. The K-CSP–2 was correlated with the K-SP and the K-BASC–2. Children with ASD had higher K-CSP–2 scores than TD children. The discriminant analysis classified children with ASD and TD children with an overall accur...
Evaluating cross-cultural equivalence of the Korean MMPI-2 via bilingual test–retest
International Journal of Intercultural Relations, 2006
Previous efforts to establish the cross-cultural equivalence of the Korean MMPI-2 have focused on analysis of internal structure and peer behavioral correlates using only a Korean college sample. The intent of this study was to provide further evidence of the cross-cultural equivalence of the Korean MMPI-2 using a bilingual test-retest method. Fifty-three self-reported bilinguals living in the US completed both the MMPI-2 in Korean and English within a 1-week interval. Their profiles were compared to previously established test-retest reliabilities. Cross-language correlations were sizable, but substantially lower than the published within-language test-retest correlations. However, when a proficient bilingual subsample was selected from the original sample post hoc, cross-language correlations were more similar to test-retest reliabilities. Cross-language item analysis revealed that items with simple and direct grammar had the highest item agreement. Complicated sentences, such as those containing double negatives or unique American idioms, had the least concordance. r . Despite wide use and acceptance by the Korean psychological community the validity and reliability of this original version remained largely untested, and serious translation problems (including miskeying) were identified . In 1989, the Korean MMPI was retranslated and standardized with a large normative sample . Although all items were properly keyed in the same direction as the original English version, the new translation appeared not to correct many distortions present in the original translation, and added others. Further, the simultaneous release of the English MMPI-2 (Minnesota multiphasic personality inventory-revised) made this version obsolete as it was released.
Visual Perceptual Skills (non-motor) among Adults in Selangor of Malaysia
Medicine & Health, 2020
Visual perceptual skills are important skills for an adult to carry out their daily activities such as reading, writing and driving, successfully. This study was conducted to determine the visual perceptual skills (non-motor) of a group of adults in Selangor, Malaysia. A total of 120 subjects from Selangor with the age ranging from 20 to 59 years were randomly recruited in this cross-sectional study. This study involved distance and near visual acuity measurements using Snellen chart and Universiti Kebangsaan Malaysia (UKM) near vision chart, cognitive screening tests using the Mini Mental State Examination questionnaire (MMSE) as well as visual perceptual skills assessment (non-motor) using the Test of Visual Perceptual Skills (Non-Motor)- Revised (TVPS-R). The mean age of the subjects was 39.41+11.81 years old. Results showed that the mean standard scored obtained for Visual Discrimination (VD), Visual Memory (VM), Visual-Spatial Relationships (VSR), Visual Form Constancy (VFC), V...

This study investigated the relationship between the Developmental Coordination Disorder Questionnaire 2007 (DCDQ’07) and the Bruininks-Oseretsky Test of Motor Proficiency Second Edition (BOT-2) in Korea. This study also adjusted the cutoff score of the DCDQ’07 based on the BOT-2 for Korean children. A total of 256 children were recruited from communities in Korea. They were divided into two age groups: 8 to 9 years old and 10 to 12 years old. Children performed the BOT-2, and their parents completed the DCDQ’07. The correlation between the DCDQ’07 and the BOT-2 was analyzed. The adjusted DCDQ’07 cutoff score for Korean children was calculated using the BOT-2 as the criterion through a receiver operating characteristic curve. A significant correlation between the DCDQ’07 and the BOT-2 was found, indicating that Korean parents’ perception of children’s motor skills was related to their children’s actual motor proficiency. The adjusted cutoff score of the DCDQ’07 had a sensitivity of ...
