방사선사의 직무 스트레스 측정도구 개발을 위한 요인별 신뢰도 분석

Abstract

The present study is designed to analyze reliability and validity of the instruments used to measure job stress of radiologicaltechnologists mainly by means of the questionnaires from Korean edition of NIOSH check list. The subjectsof this study are 890 radiological technologists active at 44 general hospitals in 16 provinces and cities across the country.The item-total reliability revealed that 10 factors in 6 are the major causes of stress in job life of radiological technologists.The measuring instrument proved to be valid with reliability coefficient of internal consistency by factorsbeing more than 0.7. The factors found to be applicable herewith include limit and authority of job (0.73), cohesionwithin departments (0.86), resources control (0.81), mental requirements (0.85), job load (0.82), and job stability (0.72).When job autonorny item of causes are modified for proper use to radiological technologists, the measuring instrumentsare expected to show high reliability. It seems, however, necessary to develop a measuring instrument to analyze anduse the validity of related measuring instruments since the reliability here was rated low, with statistical coefficientslower than 0.7 in such factors as job management (0.57), conflicts within departments (.1.13), sense of responsibilityfor patients (0.66) and usage of education (0.26). As this study was intended to examine reliability and validity of theconcepts related to measurement of job stress on the part of radiological technologists, it may not be proper to applythe results of this study to general use, but is advised to utilize them as basis for developing instruments to verify reliabilityand validity by comparing with and analyzing other measuring instruments
