This study aimed to develop a scale to measure physical health behaviors among social work clients using general services. The scale items were constructed based on literature review and FGI of social workers. Exploratory factor analysis and confirmative factor analysis affirmed the factor structure of Physical Health Behavior Scale with two sub-scales: Health Promotion Behavior Scale and Health Hindrance Behavior Scale. Promotion Scale had 7 factors and Hindrance Scale had 5 factors. Both sub-scales showed acceptable ranged goodness-of-fit for the model, and internal consistency test proved that the scale was reliable. The analyses of discriminant validity, convergent validity, and concurrent validity resulted significant validation. Based on those results, the developed Physical Health Behavior Scale were proved well-constructed, reliable and valid. The Scale will be utilized for both clients in general to check their own health related behaviors and social workers to adopt as a tool for assessment in order to perform an evidence based practice.

Objective : The objective of this study was to determine a discriminat validity of the Sensory Processing Scale-Children (SPS-C) for children with and without Sensory Processing Disorder (SPD). Method : The SPS-C was completed by parents of 151 Korean children including 68 typically developing children (control group), 83 children with SPD (known group) in the age range 3-5 years, in South Korea. ANCOVA with sex as covariable was used to identified the difference between the children with typically development and SPD. Results : Sensory processing differences in sensory domains and sensory factors were detected and the gender differences were not effective between typically developing children and children with SPD. Significant differences were found in all sensory domain score and total score except proprioceptive processing in sensory domain. In sensory factors, significant differences were found in overrsensitivity, underresponsivity, and discrimination, but sensory seeking was not significant. SPS-C was a valid assessment tool to identify or screen of SPD in Korea. Conclusion : The psychometric characteristics for the standardization study of SPS-C were presented, and the discriminant validity to screen the children with sensory processing problems was presented as a verified evaluation tool. SPS-C will be helpful in screening, analyzing and interpreting characteristics of sensory processing, and establishing an intervention plan.

The purpose of this study was to examine the validity of the Manual Ability Classification System (MACS) by analysing of relation between MACS and Jebsen-Talyor Hand Function Test. The concurrent validity was examined by calculation of correlation between MACS and Jabsen-Talyor Hand Function test and the discriminant validity was examined by measurement of hand function difference according to MACS level. For this, eighty-one children with spastic cerebral palsy were employed in this study. The children were evaluated by using the MACS and Jebsen-Taylor Hand Function Test for their hand function. There were a significant correlation between the MACS and Hand function (r = .870, p < .05). The good correlation between the MACS and subtest of Jabsen-Talyor Hand function (p < .05). The hand function according to the MACS level were different significantly (p < .05). The MACS is valid classification system for assessment of hand function of children with cerebral palsy. The MACS in practice will provide usefulness for assessment of hand function in children with spastic cerebral palsy.

The OSPG(Observation Scale for Parents of the Gifted in Korean Traditional and Western Music) is one of the tools for screening of the Gifted in Korean traditional and Western music. So the validity and reliability of the OSPG has an influence on securing validity of the whole identification process. The purpose of this study is to examine the validity and reliability of the OSPG-2 that input screening processing, and to suggest systematization of identification processing for the Gifted in Korean traditional and Western Music. For the achievement of this purpose, this study administered the OSPG-2 to 261 gifted students aged between 13 and 16 in the middle or high school for the arts. To validate the OSPG-2, I analyzed items of the OSPG-2, and conducted the exploratory and confirmative factor analysis. I also examined the internal consistency. As a result of the exploratory factor analysis, I collected 40 items of the OSPG-2 finally. Furthermore, I could identify psychological construct of the Gifted in Korean traditional and Western Music. The consequence of confirmative factor analysis, the model provided good fit to observed data. As a result of reliability analysis, the internal consistency of the internal characteristic verified Cronbach's ${\alpha}$=.939, and the internal consistency of the external environmental characteristic verified Cronbach's ${\alpha}$=.887. This result of validity study reflects the fact that the OSPG-2 is a valid scale and is able to input to gifted educational field instantly.

This study was performed with a view to examine the nature and difference of EFA(Exploratory Factor Analysis) and CFA(Confirmatory Factor Analysis), and to compare the analysis process and result of EFA and CFA with the same data. The result of empirical analysis was as follows. Meanwhile, p.1, p.3 was removed owing to hampering the convergent validity in EFA, p.3 was removed owing to hampering the discriminent validity in CFA. EFA was reduction process of muti measurement variables to a few factor, but CFA was understanding and confirmatory process of measurement and latent variables' relation. Eventually, this study showed that EFA and CFA used different methology, thus the different outcomes appeared although using the same data, and implicated resonable application of methology according to given data.
