Examples of validated questionnaires in assessing cognitive function.
| Subjective assessment of cognition | Description | Scores |
|---|---|---|
| Functional Assessment of Cancer Therapy- Cognitive Function (FACT-Cog)87 |
37-Item questionnaire is divided into six cognitive domains: memory, concentration, mental acuity, verbal fluency, functional interference, and multitasking ability. |
Range from 0 to 148, with higher scores indicating better cognitive functioning |
| European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-C30)77,88 |
30-Itemquestionnaire, two items [cognitive functioning scale (EORTC-CF)] that assess the cognitive domains of concentration and memory |
Range from 0 to 100, with higher scores indicating better perceived cognitive function |
| Cognitive Failures Questionnaire89 | 25-item, 4 point Likert scale, self-report measure of everyday cognitive lapses such as forgetting appointments or where one has left things (e.g. keys, wallet), lapses in concentration or attention, or word-finding difficulty |
Range from 0 to 100, higher scores on the CFQ are indicative of greater number or severity of cognitive complaints. |
| Multiple Abilities Questionnaire (MAQ)90 | Self-report measure of cognitive problems encountered in daily life. Each of the 48 items is rated on a 5-point scale for frequency of cognitive lapses or successes yielding a total score, as well as scores for 6 domains (attention, language, remote memory, verbal memory, visual–spatial memory, and visual–spatial perception). |
Range from 0 to 240, higher scores indicating worst perceived cognitive function |
| Self-perceived deficits in attention (FEDA) and for subjectively experienced everyday memory performance (FEAG)73,74 |
27 items in FEDA and 29 items in FEAG, each item is rated on a 5-point scale. FEDA assesses self-rated distractibility and retardation of mental processes, fatigue and retardation in activities of daily living and decrease in motivation. FEAG assesses forgetfulness. |
Range from 27 to 135 in FEDA, 29–145 for FEAG, lower scores indicating worst perceived cognitive function |
| Mini-mental State Examination (MMSE)68 | Brief screening test for cognitive deficits, covers a number of domains in orientation, registration, attention and calculation, recall, language, and copying. |
Range from 0 to 30, higher scores indicating better cognitive function |
| Montreal Cognitive Assessment (MOCA)91 | Screening test for cognitive deficits, covers a number of domains in short-term memory, visuospatial abilities, executive functions, attention, concentration, and working memory |
Range from 0 to 30, higher scores indicating better cognitive function |
