The purpose of this study was to validate Preschool Child Observation Record-II developed by High/Scope for Korean preschool children. The subjects of the study were 255 children aged three to six attending child care centers and their head teachers. They were observed for at least two months and completed the Korean version of Child Observation Record-II(K-COR-II). K-COR-II consisted of six categories and 32 items which had five-level-rubrics. The results from an exploratory factor analysis identified one dimension of the scale, there was no evidence of discriminant validity even after face validity was examined. The concurrent validity and internal consistency of the revised scale were relatively high. Also, the mean between the upper and lower groups with regard to item discrimination showed significant difference. It was concluded that K-COR-II can be used as a valid and reliable instrument to various aspects of preschool children's development.

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.

This study consisted of methodological research verifying the validity and reliability of the Korean version of the interpersonal emotion management (IEM) strategies scale after translating and modifying the scale developed by Little et al. The study verified the content validity, construct validity, concurrent validity and reliability based on 189 nurses working at four hospitals in the Seoul and Gyeonggi region. In this study, the Korean version of the IEM strategies scale was comprised of four factors, with a total of 15 questions that included three regarding situation modification, three regarding attention deployment, four regarding cognitive change, and five on modifying emotional response. Furthermore, verification of concurrent validity revealed that the Korean version of the IEM strategies scale was a valid tool as the correlation of the emotional intelligence scale appeared as r=0.60 (p<0.001). The reliability verification showed four factors at Cronbach's ${\alpha}=0.84-90$, confirming that the Korean version of the tool in this study was very reliable.It is important to note that this study provided basic data for the development of educational programs that can effectively control the negative emotions of clinical nurses at the organization level.

The purpose of this study is to validate the Play Participation Attitude Scale for parents of preschoolers, which was developed by the Delphi survey. 447 parents of 9 daycare centers in Seoul and Incheon were recruited for this study and, finally, data from 339 parents were used to perform exploratory factor analysis, confirmatory factor analysis, correlation analysis, multiple regression analysis, and reliability analysis. The results of the study are as follows. First, factor analyses revealed that the global fit of the sensitively play (7 items), responsively play (6 items), and delightfully play(7 items) three-factor model was good. Second, the internal consistency of the Play Participation Attitude Scale was good. Third, there was a statistically significant positive correlation between the current scale and the parents' playfulness scale, indicating concurrent validity. Finally, higher scores of the Play Participation Attitude Scale and its three factors significantly predicted lower scores of parenting stress and higher scores of the preschoolers' self-control ability. These findings revealed that this new measure to be both valid and reliable and specifically suggests what kind of attitude is appropriate for parents to adopt when participating in preschoolers' play.

This study was conducted to develop the Sexually Transmitted Infections (STI) Knowledge Scale for adolescents. Based on a literature review, the first preliminary 40 questions were created, which content validation by expert reviewers and a pilot study then refined into a draft scale of 29 items. To confirm the validity and reliability of this preliminary scale, data were collected from 141 adolescents between February 13 and 26, 2016: factor analysis resulted in a factor loading of more than .52, while convergent validity revealed that the group receiving STI education was significantly higher (p=.009). The final version of the scale contained 16 items, with a reliability measured by Cronbach's ${\alpha}$ of .85 and the 39.3% of correct answers. The STI knowledge scale developed in this study is a valid scale that can be used to evaluate the effectiveness of STI education for adolescents.

The development process from creative potential to realized talent is complex and non-linear. This feature of the process stands out more in the process of living a creative life in the long-term rather than in a situation to solve certain problems in the short-term. The purpose of this study is to develop Creativity Path Inventory (CPI) for undergraduate students based on Sawyer's Zigzag Model which is one of creative process theories and to verify reliability and validity of the inventory. Thus, reflecting the characteristics of each stage of the model, this study developed 88 items in 8 factors and finally confirmed 38 items in 7 factors through item analysis and verification process on construct validity. Internal consistency of a total of 38 items in CPI turned out to be .835, confirming the reliability of the inventory and goodness-of-fit index of the final model also demonstrated an appropriate result. CPI with verified reliability and validity will help enable people who want to manifest creativity in view of everyday creativity to realize self-improvement by self-reporting their strengths and weaknesses on their own.

Client satisfaction has been getting more attention in the field of social work in Korea. However, there have been very few standardized tools to measure the construct. The purpose of this study is to develop the Korean version of the Client Satisfaction Inventory developed by McMurtry and Hudson. This study was conducted with a total of 259 clients of 6 social service agencies in Seoul metropolitan areas. Based upon the results of factor analysis, the Korean version of the Client Satisfaction Inventory(CSI-K) is considered a two-factor measure. The alpha coefficients of the subscales of the CSI-K are .964 and .885 which are considered very high. The subscales are significantly correlated with convergent variables and very weakly correlated with discriminant variables. It is suggested that scales more suitable for social work settings in Korean be developed.
