Abstract:
Fatigue, the most frequently reported symptom of cancer and its treatment, is highly disruptive and negatively impacts quality of life (QOL). Fatigue, a poorly understood multi-dimensional symptom evading easy definition, is often overlooked or under-treated. Several cancer-related fatigue measures exist. The symptom may be contained as a single item or scale in self-report QOL instruments. Fatigue intensity using numerical or visual analogue scales has been explored. Alternatively, biologic, cognitive and/or psychological characteristics of fatigue have been measured. Several existing tools are lengthy and not sensitive to change over time. No available tool specifically measures the impact of fatigue on daily living. The purpose of this study was to develop a simple self-report instrument to examine the impact of fatigue on patients’ abilities to engage in daily activities while undergoing cancer treatment. Several models of fatigue focus on conceptual descriptions or manifestations. Others describe the impact of fatigue on QOL. An alternative model exploring the meaning of fatigue in everyday life suggests that patients perform self-care to relieve fatigue when daily life is impacted. Using a convenience sampling approach, 135 adults receiving chemotherapy from 7 ambulatory cancer centers completed a 9-item scale on day 1 of cycle. Respondents rated how much fatigue affected their ability to perform increasingly more challenging daily activities according to 3 response categories – not at all, a little, or a lot. In addition, respondents rated the relevance of fatigue to overall QOL. Demographic data collected included age, gender, tumor type and stage, anti-neoplastic agents, and treatment cycle. The Rasch measurement model was used to evaluate internal and construct validity of the scale. Mean square (MNSQ) fits statistics for all items were within the specified criteria (> 0.6 - < 1.4) demonstrating that items formed a unidimensional construct supporting internal validity. The hierarchical ordering of items from most to least fatiguing followed clinical expectations, providing evidence for the construct validity of the scale. Ninety five percent of subjects were within the specified MNSQ criteria suggesting this scale validity measures fatigue in persons undergoing chemotherapy. Recent research indicates that patients will use strategies to manage fatigue when it causes disruption in daily life. Understanding the impact of fatigue on daily activities represents an important measure to optimize management strategies.
