  • 자기자비 척도(Self-Compassion Scale: SCS)는 Neff(2003a)에 의해 개발되었고, 국내에서는 김경의, 이금단, 조용래, 채숙희, 이우경(2008)에 의해 번안 및 타당화 되었다. 하지만, 원척도와 한국판 자기자비 척도가 대학생만을 대상으로 타당화 한 제한점이 있고, 자기자비 척도의 요인 구조가 일관되지 않는다는 국외 연구 결과도 보고되고 있다. 따라서 본 연구에서는 18세에서 79세의 성인 435명을 대상으로 설문한 자료를 바탕으로 자기자비 척도의 요인 타당성을 검증하였다. 이를 위해 탐색적 요인분석과 확인적 요인분석을 실시하였고, 확인적 요인분석에서는 2요인, 3요인, 6요인 구조 세 가지 모형으로 구성하여 모델의 적합도를 비교 검증하였다. 분석결과, 탐색적 요인분석에서 6개의 요인이 나타났으며, 확인적 요인분석에서도 6요인 구조가 가장 적합한 것으로 나타났다.

  • The purpose of this study was to develop the Resilience Scale for Children(RSC) and to evaluate its reliability and validity. The RSC was administered to 482 children in grades 4 through 6. Factor analysis of the 30 item scale demonstrated Cronbach's ${\alpha}=.89$ for internal consistency of total items. The results of the confirmatory factor analysis supported a five-factor structure. Retest stability was acceptable for the five-factors. Tests of the present scale for criterion-related validity compared favorably with Self-Perception Profile for Children (Lee, et al., 1992) and the Stress Coping Behavior Scale for Children (Kim and Kang, 2003) confirming its applicability to elementary school students for assessment of resilience.

  • 측정도구의 구조타당도는 내용타당도 이후 가장 먼저 수행되어야 할 측정 속성이다. 이를 위해 국내 간호학에서는 주로 CFA를 사용하는데, CFA로 얻을 수 없는 정보들을 제시하는 IRT/라쉬 분석도 같이 적용해 볼 것을 추천한다. 구조타당도 이외에 내적일관성 및 교차문화타당도/측정동일성 또한 측정도구의 내적구조를 확인하기 위한 것이다. 국내 간호학 측정도구 연구에서 교차문화타당도/측정동일성에 대한 검증은 거의 찾아볼 수 없는 상황이다. 따라서 앞으로는 이에 대한 평가도 시행되기를 바란다.

  • Purpose: This study aimed to develop and test a reward scale for hospital nurses. Methods: The initial items were identified through a literature review and focus group interviews with ten hospital nurses. The content validity of the items was evaluated by ten experts. Fifty-one items were derived from the pilot survey. Four hundred eighty-eight nurses participated in the study: 248 for exploratory factor analysis (EFA) and 240 confirmatory factor analysis (CFA). Data were analyzed using item analysis, EFA, CFA, convergent validity, known-group validity, and internal consistency using IBM SPSS Statistics 29.0 and IBM SPSS AMOS 29.0. Results: The final scale consisted of 31 items and eight factors (decent wage, opportunity to grow and develop, support for special situations, various benefits, flexibility of work, job-related achievement, reflecting career and performance, and recognition), which explained 67.3% of the total variance. The eight-subscale model was validated by CFA. Convergent validity was evaluated by analyzing correlation with intention to leave (r = - .63, p < .001) and job satisfaction (r = .54, p < .001). The known-group validity was evaluated by comparing the reward scales according to age, clinical career, income level and hospital type. The scale was found to be reliable with a Cronbach's α of .89. Conclusion: Both the validity and reliability of the reward scale for hospital nurses are verified, which can enhance the understanding of the range of rewards and may assist nurse managers in establishing an effective reward system.

  • 본 연구의 목적은 Ohio State Teacher Efficacy Scale(OSTES)을 활용하여 예비유아교사 교사효능감 척도(PS-TES)를 타당화 하는데 있다. 이를 위한 본 연구는 G지역에 소재한 3년제 대학 유아교육과 3학년 재학생 428명을 대상으로 설문지를 실시하였다. 척도의 타당도와 신뢰도를 확인하기 위해 탐색적 요인분석과 신뢰도(Cronbach's ${\alpha}$)계수, 상관분석 및 확인적 요인분석(CFA)을 실시하였다. 본 연구의 결과를 연구문제를 중심으로 살펴보면 다음과 같다. 첫째, 예비유아교사 교사효능감 척도(PS-TES)의 하위요인을 살펴보기 위해 탐색적 요인분석 결과 3개의 하위요인(교수전략 효능감, 학생참여 효능감, 교실관리 효능감)으로 나타났으며 총 문항은 12문항으로 이루어졌다. 예비유아교사 교사효능감 척도(PS-TES)의 하위요인 신뢰도는 '교수전략 효능감' .82, '학생참여 효능감' .72, '교실관리 효능감' .76으로 나타났으며 전체 신뢰도는 .87로 나타났다. 둘째, 예비유아교사 교사효능감 척도(PS-TES)의 타당도를 살펴보기 위해 확인적 요인분석(CFA)을 실시한 결과 모델 적합도는 CMIN/DF = 1.59, RMSEA = .05, SRMR = .05, NNFI = .96, CFI = .97로 나타나 예비 유아교사 교사효능감 척도(PS-TES)가 적합한 측정 도구임이 확인되었다.

  • Objective: This study was to identify whether working memory (WM) can be clearly subdivided according to auditory and visual modality. To do this, we administered the most recent and universal clinical WM measures in a mixed psychiatric sample. Methods: A total of 115 patients were diagnosed on the basis of DSM-IV diagnostic criteria and with MINI-Plus 5.0, a structured diagnostic interview. WM subtests of Korean version of Wechsler Adult Intelligence Scale-IV and Korean version of Wechsler Memory Scale-IV were administered to assess WM. Confirmatory factor analysis (CFA) was used to observe whether WM measures fit better to a one-factor or two-factor model. Results: CFA results demonstrated that a two factor model fits the data better than one-factor model as expected. Conclusion: Our study supports a modality model of WM, or the existence of modality-specific WM systems, and thus poses a clinical significance of assessing both auditory and visual WM tests.

  • The Korean version of the Multidimensional Students' Life Satisfaction Scale for children(K-MSLSS) assesses children's subjective perceptions of Life Satisfaction(LS) in five conceptually relevant domains : Friends, School, Family, Living Environment, and Self. The purpose of the present study was to validate the five-factor structure of the K-MSLSS using Confirmatory Factor Analysis(CFA) procedures by means of the AMOS 7.0 statistical program. Of the 681 children(10.5 years, SD=1.1) recruited from three public elementary schools in Seoul 431 children were the calibration sample and 430 children were the validation sample. Results of the analyses found that the five-factor structure of K-MSLSS is applicable for use with Korean children from 9-12 years of age regardless of gender.

  • Purpose: This study aimed to validate the Child Healthy Lifestyle Profile as an instrument for screening healthy behaviors in school-aged children in South Korea. Methods: Self-reported questionnaires were administered to 454 students, comprising elementary-school students (n=221) and child cancer survivors (n=233). Reliability and validity were assessed using Cronbach's α, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA). Results: Cronbach's α, as a reliability test, was 0.87. Varimax rotation yielded nine factors with eigenvalues greater than 1 in the EFA, which explained 61.0% of the total variance. In the CFA, both convergent and discriminant validities were acceptable. Therefore, the Child Healthy Lifestyle Profile was validated as an assessment tool for Korean school-aged children. Conclusion: Based on the results of this study, the Child Healthy Lifestyle Profile was identified as a reliable and valid instrument for assessing healthy lifestyles in elementary-school children in South Korea.

  • This paper proposes a new framework to predict decision performance by investigating the cognitive fit of decision makers. We assume that every decision maker has two kinds of schema: emotional and rational. Cognitive fit is believed to have a close relationship with the two schemata and decision performance. In the literature on decision performance there is few studies investigating the relationship between the two schemata and cognitive fit. Therefore, our research purposes are twofold: (1) to provide a theoretical basis for the proposed framework describing the causal relationships among the two schemata, cognitive fit. and decision performance, and (2) to empirically prove its validity in the application to an Internet shopping environment. Based on the questionnaires from 104 respondents, we used a second order, confirmatory factor analysis (CFA) model to extract valid constructs, and a structural equation model (SEM) to calculate path coefficients and prove the statistical validity of our proposed research model. The experimental results supported our research model.

  • 급격하게 발전하는 정보사회에서 사이버 상에서의 교육이 점차 보편화되고 있다. 지속적이고 평생을 통한 교육의 필요성이 증대되면서 시작된 사이버대학은 이제 17개에 달하게 되었고 이제는 양적인 증가에 더불어 질적인 수준에 관심을 기울여야 할 것이다. 그러나 일반 대학에 비해 사이버대학의 강좌평가는 아직 체계적으로 이루어지니 못하고 있는 실정이다. 본 연구에서는 사이버대학에서의 강좌를 평가하기 위한 측정도구를 개발하고, 이에 대한 양호도를 검증하였다. 이를 위해서 관련 선행연구들을 분석하여 예비평가도구를 개발하였고, 측정도구에 대한 타당성을 확보하고자 W사이버대학의 재학생 768명에게 설문을 실시한 뒤 탐색적 요인분석을 실시하였다. 또한 791명에게 2차 설문을 실시한 뒤 확인적 요인분석을 통해 개발한 측정도구의 적합성을 검증하였다. 연구 결과, 내용 설계, 교수자, 시스템, 평가, 전반적 만족도의 5개 요인이 산출되었으며, 25개 문항으로 구성된 평가도구를 최종적으로 확인하였다.
