Psychometric Properties of the 37-Item Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) scale

Abstract

Aim: To validate the French version of the 37-item Functional Assessment of Cancer Therapy-Cognitive Function, including the four items related to multitasking, previously excluded from the scoring algorithm. Materials & methods: A cross-sectional study was carried out among 261 cancer patients. Validity was confirmed by factor analyses using the principal component analysis technique. Results: Construct validity was demonstrated, and items loaded on subscales with adequate sample adequacy to factor analyses outcomes. Better cognitive functioning was noted with age and in working patients, whereas lower functioning was observed in metastatic patients. Conclusion: The 37-item French tool is valid and reliable; questions related to multitasking could be included in the score.

Effects of D‐CAG chemotherapy regimen on cognitive function in patients with acute myeloid leukaemia: A resting‐state functional magnetic resonance imaging study

“…The demographic and clinical data were acquired from all participants. In addition, cognitive function of patients was evaluated by the Functional Assessment of Cancer Therapy‐Cognitive Function (FACT‐Cog) (Cheung & Chan, 2013; Hajj et al, 2022), and rs‐fMRI data were collected from all patients before and after the treatment of D‐CAG. The flow chart of the present study was presented in Figure 1.…”

“…The cognitive function was evaluated by the Chinese version of FACT‐Cog in all patients before and after D‐CAG chemotherapy. The scale of FACT‐Cog has been widely used to assess the cognitive function of cancer patients in previous studies (Cheung & Chan, 2013; Hajj et al, 2022). Its validity and reliability have been verified in Chinese patients with breast cancer (Ding et al, 2020; Wei et al, 2022).…”

Yoga improves self-reported cognitive function among cancer survivors: results from the STAYFit trial

“…The Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) is a subjective neuropsychological instrument designed to evaluate the effects of cancer patients' perceived cognitive deterioration in their health-related quality of life (Wagner et al, 2009). The Fact-Cog is a valid and reliable questionnaire with excellent internal consistency (Cronbach's alphas for total score and sub-domains > 0.81) (Hajj et al, 2022). This 37-item scale assesses perceived cognitive impairment (20 items, score range 0-80), perceived cognitive abilities (nine items, score range 0-36), quality of life (four items, score range 0-16) and comments from others over the past 7 days (four items, score range 0-16).…”

Cognitive function and its associated factors among patients with cancer pain: a multicentre cross-sectional study in China

“…It is recognised as a significant detractor from the quality of life among those with cancer, with the associated cognitive decline profoundly impacting social engagement, employment and overall life satisfaction 4. The Functional Assessment of Cancer Therapy-Cognitive (FACT-Cog),5 with its four subcomponents, has emerged as a reliable and valid instrument for gauging cognitive impairment (CI) in this population 6…”
