  • Intolerance of Uncertainty is associated with numerous psychopathologies, including generalized anxiety disorders. However, several studies differ in the factor structures applicable for the Intolerance of Uncertainty Scale (IUS), and there exists a debate regarding the factorial and construct validity. Thus, in the current study, the IUS was newly translated to explore and verify the structures and factors relative to the cultural background of Korea. The study involved an exploratory factor analysis of randomly extracted data from 260 of 533 adults selected. Results determined that a prospective factor of 3 items and inhibitory factor of 5 items was appropriate. In addition, a confirmatory factor analysis and correlation analysis of the remaining 273 data revealed that a structural model comprising of the 8-items two factors model was well suited (x2=37.699, TLI=0.951, CFI=0.969, RMSEA=0.063, SRMR=0.039), and showed significant static correlation with worry, depression, and state-trait anxiety.

  • The purpose of this study was to verify the construct validity of self-evaluated writing scale for students with disabilities who had difficulties in writing. After interpreting the Here's How I Write scale developed by Goldstand et al. (2013), we administered Delphi survey to 40 special education professionals, calculated the content validity ratio and decided the final scale of 21 questions applicable to Korea. Additionally, we carried out the scale to 350 disabled and normal students for testing construct validity. The main results are as follows: For both students with disabilities and without disabilities, the overall internal consistency of scale are higher than .89 and the internal consistency of factors of scale are higher than .66. The confirmative factor analysis using AMOS 21.0 and SPSS 21.0 to verify construct validity showed fit index at relatively satisfactory level for students with disabilities and without disabilities. Furthermore, while there were relatively strong convergent validity and discriminant validity in the sub-factors of scale for students without disabilities, the level of convergent validity and discriminant validity were relatively lower for students with disabilities.

  • The purpose of this study is to validate learning progressions for Earth's motion and solar system from two different perspectives of validity. One is construct validity, that is whether a hypothetical pathway derived from our study of LPs is supported by empirical evidence of children's substantive development. The other is consequential validity, which refers to the impact of LP-based adaptive instruction on children's improved learning outcomes. For this purpose, 373 fifth-grade students and 17 teachers from six elementary schools in Seoul, Kangwon province, and Gwangju participated. We designed LP-based adaptive instruction modules delving into the unit of 'Solar system and stars.' We also employed 13 ordered multiple-choice items and analyzed the transitions of children's achievement levels based on the results of pre-test and post-test. For testing construct validity, 64 % of children in the experimental group showed improvement according to the hypothetical pathways. Rasch analysis also supports this results. For testing consequential validity, the analysis of covariance between experimental and control groups revealed that the improvement of experimental group is significantly higher than the control group (F=30.819, p=0.000), and positive transitions of children's achievement level in the experimental group are more dominant than in the control group. In addition, the findings of applying Rasch model reveal that the improvement of students' ability in the experimental group is significantly higher than that of the control group (F=11.632, p=0.001).

  • Academic engagement has been known as a strong predictor of students' cognitive and affective outcomes in an educational context. Despite increasing interest and theoretical usefulness of this construct, a few researchers seem to be interested in the validation of instruments to measure academic engagement for Korean students. Thus, this study would like to introduce one of academic scales widely used, UWES-S(Utrecht Work Engagement Scale-Student) (Schaufeli et al., 2002a: 2002b) and to validate the UWES-S for Korean college students. To validate the Korean version of the UWES-S, 651 college students (285 for Field Trial, 366 for Main Study) were used. The procedure is as follows. First, we used an integrated adaptation procedure to produce a Korean version of the UWES-S. Second, EFA(exploratory factor analyses) was applied to explore the factor structure of the UWES-S on the field trial data. Third, the psychometric properties of the UWES-S items were examined by graded response model(GRM). Also CFA(confirmatory factor analysis) was used to examine its internal construct validity for the data from the main study. Finally, the external validity of the UWES-S was scrutinized with the related variables such as academic motivation and satisfaction. As a result, the Korean version of the UWES-S with 13 items was accepted that the four items were excluded from its original version. Second, the internal validity was supported that the 3 factor CFA model(vigor, dedication, absorption) fit the data well. Third, we supported the partial mediation model that academic engagement played as a mediating variable between academic motivation(internal/external) and academic satisfaction. Finally, the differences between a validation of UWES-S for Korean college and high school students, the necessity of construct equivalence testing, and direction for future research of scale validating were discussed.

  • Teachers in music(including Korean traditional music) gifted education are a significant variable in both identifying the giftedness of students and a successful instruction. The purpose of this study is to develop the Scale for Screening the Qualified Teachers for the Gifted in Korean traditional and western Music(SSQTGM), and to examine the validity and reliability of the SSQTGM. To achieve this purpose, this study administered the SSQTGM to 175 teachers of gifted students aged between 13 and 15 in middle schools for the arts. To validate the SSQTGM, I analyzed the criteria of the SSQTGM, and conducted an exploratory and confirmative factor analysis. I also examined an internal consistency. As a result of the exploratory factor analysis, I finally collected 41 items of the SSQTGM. Futhermore, I could identify psychological constructs of the qualified teachers for the gifted in Korean traditional and western music. In consequence of the confirmative factor analysis, the model provided a good fit to observe data. As a result of the reliability analysis, the internal consistency of knowledge in the music(korean traditional music) verified cronbach's ${\alpha}=.937$, and the expertise of the class management and instruction verified cronbach's ${\alpha}=.942$. Also, the teachers' aptitude and personality verified cronbach's ${\alpha}=.963$. This result of the construct validation reflects the fact that the SSQTGM is an available scale that can be applied in gifted education field instantly.

  • 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.

  • The Critical Consciousness Scale (CCS) is a scale developed by Diemer and colleagues (2017) that can measure the capacity of the oppressed or marginalized people to critically analyze their social and political conditions, support societal equality, and take action to change the perceived inequities. In this study, we validated the CCS for Korea by adapting and localizing the scale and validating it among university students. Content validity was verified by having five individuals with master's and doctoral degrees in psychology evaluate the suitability of the translated items. Afterwards, reliability and validity were verified through a survey of 314 university students nationwide using the CCS, along with the opportunity inequality recognition scale, recognition of the need for environmental change scale, social participation scale, and belief in a just world scale. To verify the scale's validity, exploratory factor analysis was conducted, confirming three subfactors. Then, a confirmatory factor analysis was carried out, where 14 items out of the original 22 were retained. The construct validity and reliability of these 14 items were found to be satisfactory. Additionally, in the correlation analysis between the CCS and similar scales, a significant clear relationship was found. The CCS showed a positive correlation with scales such as opportunity inequality recognition, need for environmental change recognition, and social participation, and a negative correlation with the belief in a just world scale. Based on these results, the CCS can be considered valid and reliable. Finally, the limitations and significance of this study were discussed.

  • The purpose of this study is to conduct the Korean translation and validity of the Unconditional Positive Self-Regard Scale(UPSR) that Patterson and Joseph(2006) originally developed based on the Rogerian person-centered theory. K-UPSR was adapted, modified and validated from the UPSR Scale. This study verified reliability and validity, and factor structure of K-UPSR. The preliminary study was proceeded with twelve adapted questions to 131 undergraduate and graduate students. As a result, three questions were deleted for the low reliability. The exploratory factor analysis of the nine questions showed two sub factors. The internal consistency reliability of nine questions with two sub factors was .89 in this study. The study was conducted by 419 male and female adults and verified confirmatory factor analysis and the validity. The study data was evaluated for the suitability of convergent and discriminant validity of K-UPSR. Through the correlation analysis of other five scales, the result was mostly corresponded to the preliminary study.
