Validity of the serial seven procedure

Cognitive and physical performance are well preserved following standard blood donation: A noninferiority, randomized clinical trial

“…Serial sevens subtraction test: subjects performed as many subtractions as possible in 1 minute. Number of correct answers was considered the final score …”

Novel information processing at work across time is associated with cognitive change in later life: A 14-year longitudinal study.

“…Serial 7s. The Serial 7s Test, which has shown to have good validity and reliability, is commonly used to assess attention, mental tracking, and computation (Karzmark, 2000). Respondents are asked to subtract a serial of 7s from 100 for a total of 5 trials.…”

Beyond balance and mobility, contributions of cognitive function to falls in older adults with cardiovascular disease

“…In the semantic verbal fluency test respondents were required to name as many animals as possible in 60 seconds with the total number of named animals to comprise the score. Numeracy was measured with the serial sevens subtraction test (SST) which is a measure of concentration and attention 27,28 . For the SST respondents were required to subtract 7 from 100, then from 93 and so on for a series of 5 sequential subtractions.…”

“…For the SST respondents were required to subtract 7 from 100, then from 93 and so on for a series of 5 sequential subtractions. All numerical responses were recorded and respondents were not corrected during this process 27 . The number of numerically correct subtractions (even after error) are summed to produce the respondent's Cognition falls in cardiovascular disease total score with a maximal score of 5.…”
