Evaluation of the functional assessment of cancer therapy cognitive scale with hematopoietic stem cell transplant patients.

Abstract

The current study evaluated a newly developed self-report measure of cognitive complaints with cancer patients, the Functional Assessment of Cancer Therapy Cognitive Scale (FACT-Cog). Six or 12 months following hematopoietic stem cell transplantation, participants completed a psychosocial assessment that included the FACT-Cog and a neuropsychological assessment. Using a criterion of two or more times a week, an average of 12 of a total of 50 items were endorsed as complaints on the FACT-Cog. FACT-Cog total, domain, and subscale scores were significantly correlated with measures of depression, fatigue, anxiety, and physical and mental well-being. FACT-Cog scores, with the exception of one subscale, Other People Noticed Deficits, were not significantly correlated with cognitive performance. In general, the FACT-Cog and a commonly used measure of cognitive complaints (European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire-C30 Cognitive Functioning Scale) demonstrated similar psychometric properties. However, the FACT-Cog assesses broader aspects of cognitive complaints, thereby providing greater information about the types of cognitive complaints patients are experiencing.
