Description
Summary:The purpose of this study was to develop a quality of life instrument for longterm female cancer survivors. A factor analysis (n = 188) of 34 items resulted in the Long-Term Quality of Life (LTQL) instrument. Internal consistency was high for the four subscales: somatic concerns (alpha = .86), spiritual/philosophical views of life (alpha = .87), fitness (alpha = .92), and social support (alpha = .88). These four factors are congruent with Ferrell's four theoretical domains of quality of fife developed for women with breast cancer. Content validity was supported through interrater agreement of subscale items. Significant correlations between the LTQL and the CaRES, an established measure of quality of life, support the concurrent validity of the LTQL Construct validity was supported by differential subscale scores according to demographic and health status data. Although the LTQL retained all of Ferrell's four domains of quality of life (physical, psychological, social, and spiritual) within one instrument, individual items reconfigured to suggest an overlapping of domains for the long-term female cancer survivor. This research suggests that the LTQL warrants further testing and may be a useful measure of quality of life in long-term female cancer survivors.
