수렴, 판별 및 집합타당도를 검정하기 위해서는 연구자가 선행연구 결과를 바탕으로 검증하고자 하는 도구와 비교측정도구로 측정한 점수의 상관관계의 정도와 방향에 대한 가설을 세우고 시행해야 한다. 분석결과가 사전에 기획하였던 가설을 만족하였을 때, 그 타당도가 만족하였다고 할 수 있다. 준거타당도는 검정하고자 하는 도구가 측정하는 개념과 같은 개념을 측정하는 표준화된 도구가 있는 경우에 실시한다.

Purpose: The purpose of this study was to develop an instrument to assess bullying of nurses, and test the validity and reliability of the instrument. Methods: The initial thirty items of WPBN-TI were identified through a review of the literature on types bullying related to nursing and in-depth interviews with 14 nurses who experienced bullying at work. Sixteen items were developed through 2 content validity tests by 9 experts and 10 nurses. The final WPBN-TI instrument was evaluated by 458 nurses from five general hospitals in the Incheon metropolitan area. SPSS 18.0 program was used to assess the instrument based on internal consistency reliability, construct validity, and criterion validity. Results: WPBN-TI consisted of 16 items with three distinct factors (verbal and nonverbal bullying, work-related bullying, and external threats), which explained 60.3% of the total variance. The convergent validity and determinant validity for WPBN-TI were 100.0%, 89.7%, respectively. Known-groups validity of WPBN-TI was proven through the mean difference between subjective perception of bullying. The satisfied criterion validity for WPBN-TI was more than .70. The reliability of WPBN-TI was Cronbach's ${\alpha}$ of .91. Conclusions: WPBN-TI with high validity and reliability is suitable to determine types of bullying in nursing workplace.

Background: This study evaluated the validity and reliability of applying the Katz's Activities of Daily Living (ADL) scale in an Iranian sample of elderly oncologic patients following initial cancer treatment. Materials and Methods: The scale was translated with the forward-backward procedure to give an Iranian version. The ADL scale was then applied in a random sample of 400 oncologic patients aged 60 and older following initial cancer treatment. Assessment of the scale stability was twice, with a 14-days (two weeks) interval, to 30 (of the 400) eligible elderly cancer patients in March 2012. To measure treatment effects, the index was run with 150 patients in a three month recall, following oncology processing. Exploratory and confirmatory factor analysis was performed for assessment of construct validity of the Katz's ADL. Reliability was measured with internal consistency (Cronbach's alpha co-efficient), and test/retest (Spearman's r value) of the instrument. Criterion validity was evaluated by comparing the Katz with Physical Function (PF) subscale of SF 36. Known-group validity was approved by comparing of Katz' ADL between quartile groups of PF subscale of SF 36. Results: In our study the ADL demonstrated a high degree of internal homogeneity (Cronbach's alpha 0.923). There was a high correlation between scores of two time measurement of Katz's ADL (p value of two- related- samples test was 0.3). Construct validity showed a correlation coefficient of 0.572 between the ADL and PF scores. In factor analysis, 2 factors were extracted. Evidence for the reliability of the questionnaire was good and known group validity was approved by significant differences of ADL score between quartiles of the PF subscale of SF36. Conclusions: The results suggest that the Iranian version of ADL applied for oncologic older adult patients following initial cancer treatment is a reliable and a valid clinical instrument and comparable to those reported in other studies.

Purpose: Health-related quality of life (HRQOL) in patients with cardiovascular disease in Korea has rarely been studied, mostly due to the lack of a psychometrically validated disease-specific instrument. The purpose of this study was to develop and validate a cardiovascular specific-HRQOL questionnaire (CD-QOL). Method: The CD-QOL was developed and validated as follows; item generation, pilot study, and psychometric tests. Patients were recruited from three-university hospitals. The patients were asked to complete the preliminary questionnaire comprising the content-validated items, SF-36, and CES-D. The NYHA and KASI classifications were used to classify the functional performance of the patients. The data was analyzed using correlation, factor analysis, multidimensional scaling, multitrait/multi-item matrix, ANOVA, and Cronbach's alpha. Result: Preliminarily, thirty-nine items were generated. Factor analysisextracted a five-factor solution with a total of twenty-two items. One item was deleted based upon the MDS. The remaining items were moderately correlated with the subscales of the SF-36 and associated with depression measured with the CES-D. The mean scores of patients in NYHA and KASI class I were significantly higher than those in NYHA and KASI class II or/and III, which suggested patients with better functional performance were likely to have a better HRQOL. Cronbach's alphas of the total and subscales were all greater than 0.70. Conclusion: The CD-QOL is a easily applicable instrument with excellent psychometric properties of content, criterion, factorial, convergent, and known-groups validity, and internal consistency reliability in Korean patients with cardiovascular disease.

본 연구는 간호사가 경험하는 직장 내 괴롭힘의 영향을 측정하기 위한 도구를 개발하고, 개발된 도구를 검증하려고 하였다. 간호사의 직장 내 괴롭힘 관련 문헌과 간호사 심층면담을 통해 28문항의 직장 내 괴롭힘 결과의 초기문항을 개발하였고, 내용타당도와 안면타당도의 확인과정에서 14개 문항을 도출하였다. 2013년 10월 21일부터 2013년 10월 28일 수도권의 의료기관에 근무하는 경력 6개월 이상의 간호사 458명을 대상으로 도구에 대한 신뢰도와 타당도를 평가하였다. 연구결과인 간호사 직장 내 괴롭힘 결과 측정도구(WPBN-CI)는 신체적 심리적 위축, 간호의 질 저하 및 불신 증가로 구성된 총 13개 문항, 3개 요인이 62.9%를 설명하였고, 수렴타당도 및 판별타당도는 각각 100%, 89.7%이었다. 우울점수가 높은 집단일수록 괴롭힘의 결과점수가 높아 집합타당도가 입증되었고, 우울척도와의 상관관계가 .70이상으로 준거타당도를 보였다. 이 도구의 Cronbach's alpha는 .90이다. 본 도구는 간호사들의 직장 내 괴롭힘으로 인한 결과 를 사전에 파악하고, 이를 통해 조기예방 및 해결방안을 모색하는 데 도움을 제공할 것이다. 또한, 직장 내 괴롭힘을 경험한 대상자들을 위한 프로그램 실시 효과성을 입증하는 도구로 사용가능할 것이다.
