“…The fifth item in the PF scale was also somewhat problematic, and did not satisfy the item convergence validity. The low correlation coefficient of this item with its scale (r= 0.28) might have been due to the skewed frequency distribution of the responses (315 patients responded with "not at all") ( Table 3); this problem has been reported previously (1,4,14).…”

“…Thus, it is essential to quantify the HRQOL in cancer clinics and clinical trials. Even though there is no universally accepted definition for HRQOL, it is generally assumed to have multidimensional constructs, with dimensions broadly related to health, such as physical, psychological and social functioning and symptoms (1). Within the context of the multidimensional constructs, several cancer-specific QOL measurements have been developed over the last decade.…”

Multidimensional Constructs of the EORTC Quality of Life Questionnaire (QLQ-C30) in Korean Cancer Patients with Heterogeneous Diagnoses

Purpose: The aim of this study was to evaluate the multidimensional constructs of the EORTC Quality of Life Questionnaire (QLQ-C30) in patients with cancer, employing not only the commonly used multitrait scaling analysis and interscale correlations, but also the factorial and multidimensional scaling (M DS) analyses.Materials and Methods: A total of 334 Korean cancer patients participated in this cross-sectional study. All patients completed the QLQ-C30.Results: W ith the multitrait scaling analysis, the cognitive functioning scale did not meet item convergent and divergent validities. W ith the interscale correlations, the physical and role functioning scales were found to be highly correlated; this was also evident in the factorial analysis. The MDS showed that each item within the social, emotional, global health status/quality of life, and nausea/ vomiting scales were clustered close together, but far from those of the other scales.Conclusion: The authors conclude that the four way evaluation of the QLQ-C30 produced results that supported the original hypothesized constructs. However, the physical and role functioning scales were not distinctive, and that of the cognitive functioning was somewhat problematic in the Korean population with cancer.

“…Perceived health status has been used successfully to assess global health among individuals with HIV, cancer, and cardiac conditions (Avis et al, 1996;Bjordal & Kaasa, 1992;Ringdal & Ringdal, 1993;Smith, Shelley, & Dennerstein, 1994;Wu et al, 1991). Perceived health incorporates patients' perspective about their health status; it also reliably predicts morbidity and mortality (Franks, Gold, & Fischella, 2003).…”

This study examines the predictors of perceived health status among homeless adults with latent tuberculosis (TB) in Los Angeles, especially in relation to gender differences. Total, 415 men and women enrolled in a TB-adherence trial completed baseline assessments concerning health status. Results indicated that women were more likely than men to report being in fair or poor health and to have experienced health problems. More women than men self-reported daily drug use and poor mental health. Homeless women were also more likely than their male counterparts to receive support from non–drug-users. Homeless adults who reported fair or poor health were also more likely than those who reported better health to have used injection drugs, to report experiencing depressive symptoms and poor mental health, and to have been homeless more than 3 years. Predictors of fair or poor health included being female and experiencing more depressive symptoms.

“…This is a valid and reliable cancerspecific QoL tool that has been used extensively in international clinical trials (Bjordal & Kaasa 1992;Hjermstad et al, 1995;Coates et al, 1997). The aim of this study was to evaluate the use of the scored PG-SGA as a measure of nutritional status in ambulatory patients receiving radiotherapy to the head, neck, abdominal or rectal area and to determine if there is an association between the PG-SGA and QoL scores.…”

The scored Patient-generated Subjective Global Assessment (PG-SGA) and its association with quality of life in ambulatory patients receiving radiotherapy

Objective: To evaluate the scored Patient-generated Subjective Global Assessment (PG-SGA) tool as an outcome measure in clinical nutrition practice and determine its association with quality of life (QoL). Design: A prospective 4 week study assessing the nutritional status and QoL of ambulatory patients receiving radiation therapy to the head, neck, rectal or abdominal area. Setting: Australian radiation oncology facilities. Subjects: Sixty cancer patients aged 24-85 y. Intervention: Scored PG-SGA questionnaire, subjective global assessment (SGA), QoL (EORTC QLQ-C30 version 3). Results: According to SGA, 65.0% (39) of subjects were well-nourished, 28.3% (17) moderately or suspected of being malnourished and 6.7% (4) severely malnourished. PG-SGA score and global QoL were correlated (r ¼ 7 0.66, P < 0.001) at baseline. There was a decrease in nutritional status according to PG-SGA score (P < 0.001) and SGA (P < 0.001); and a decrease in global QoL (P < 0.001) after 4 weeks of radiotherapy. There was a linear trend for change in PG-SGA score (P < 0.001) and change in global QoL (P ¼ 0.003) between those patients who improved (5%) maintained (56.7%) or deteriorated (33.3%) in nutritional status according to SGA. There was a correlation between change in PG-SGA score and change in QoL after 4 weeks of radiotherapy (r ¼ 7 0.55, P < 0.001). Regression analysis determined that 26% of the variation of change in QoL was explained by change in PG-SGA (P ¼ 0.001). Conclusion:The scored PG-SGA is a nutrition assessment tool that identifies malnutrition in ambulatory oncology patients receiving radiotherapy and can be used to predict the magnitude of change in QoL.
