Measuring quality of life of long-term breast cancer survivors: the Long Term Quality of Life-Breast Cancer (LTQOL-BC) Scale.

The authors developed a quality-of-life measure specific to long-term breast cancer survivors. Participants were women diagnosed with early-stage disease ≥ 7 years postdiagnosis. The final scale is the result of an iterative interview process with the 28-item scale administered to 285 participants. Factor analysis demonstrated with seven domains: physical, sexual and cognitive function, body image, coping, social support, and anxiety. Cronbach's alpha is .88. Convergent and divergent validity are also reported. The Long Term Quality of Life-Breast Cancer Scale has domains specific to breast cancer and will be useful to psychosocial and clinical researchers.
