Construction Of Methods In Measuring The Quality Of Life Outcomes Of Cancer Patients

American Cancer Society reported that cancer had not only become one ofthe world’s killers, but also it was likely to become the main human death reasonin recent years. In view of being difficult to cure malignant tumors, The ultimategoal of treatment is improving the quality of life of patients. So quality of life ofcancer patients becomes an important area in the medical field, and also animportant part in the field of cancer research. The evaluation of the quality of lifeusually uses the WHOQOL-100, the FACT-G or EORTC QLQ-C30scales athome and abroad. The scales which are commonly used in China are the Chineseversion translated from these scales. Due to the different culture and nation, it’scrucial to construct our quality of life scale in clinical.In this study,103cancer patients,10immediate family members and10clinicians were selected as subjects. Using the methods of document analysis,critical incident interviews and expert methods to extract the relevant factors ofthe quality of life, We had formed the model about the quality of life of cancerpatients by confirmatory factor analysis, then, model of quality of life of thecancer patients was construct, and verify the consistency reliability, content validity and criterion-related validity.105cancer patients were surveyed in ahospital with an aim to establish the norm. Finally, affected factors on quality oflife were discussed through96cancer patients in a hospital. Promoting cancerpatients’ quality of life will provide theoretical and clinical work. The mainconclusions of this study are as follows:1. Through Confirmatory Factor Analysis and Delphi Method, weestablished the model of quality of life of cancer patients, which contained39items in four dimensions which are physical condition, psychological condition,social function and family condition.2. To test cancer patients’ quality of life scale, statistical analysis waspreferable. The index of Cronbach’s-α was from0.739to0.911,whichdemonstrated that the scale had a higher consistency reliability; according topsychologist and medical experts’ analysis, it was generally believed that thescale was suitable for clinical and content validity was extremely great; as acriterion with WHOQOL-100and the EORTC QLQ-C30scales, we verified thecriterion-related validity on the scale, which indicated that the dimensions weresignificant relation with criterion validity of the scales of quality of life, The scalehad a higher consistency reliability, content validity and criterion-related validity.3. In this study, the norm was established. Total score which was higher than166.30was the group of high quality of life, the score which was between111.48and166.30was medium group, score which was lower than111.48was the lowgroup, and less score, lower quality of life. In physical condition, score whichwas higher than31.32was the group of high quality of life, the score which wasbetween19.32and31.32was medium group, score which was lower than19.32was the low group, and less score, lower physical function. In psychologicalcondition, score which was higher than66.68was the group of high quality of life, the score which was between44.26and66.68was medium group, scorewhich was lower than44.26was the low group, and less score, lowerpsychological function. In social function, score which was higher than34.88was the group of high quality of life, the score which was between22.54and34.88was medium group, score which was lower than22.54was the low group,and less score, lower social function. In family condition, score which was higherthan38.86was the group of high quality of life, the score which was between19.92and38.86was medium group, score which was lower than19.92was thelow group, and less score, lower family function.4. The study found that there was no significantly relationship betweengender, marital status, whether surgery and quality of life of cancer patients, butthere was significantly relationship between age, degree of education and qualityof life of cancer patients. The elder cancer patients had the higher the quality oflife and the higher education had higher the quality of life of cancer patients.
