To develop a reliable and valid test of cognitive function suitable for patients with severe cognitive impairment. Administration of a test; test‐retest reliability; comparison to traditional test. Chronic long‐term‐care facility. The participants were 40 elderly residents with severe cognitive impairment. Results of the Test for Severe Impairment (TSI) and its subsections (language, memory, executive function, and motor performance); correlation of test and retest scores; correlation of TSI with Mini‐Mental State Exam. The TSI was significantly correlated with the Mini‐Mental State Exam (r = 0.83, P ≤ 0.0001). Test‐retest reliability was high (r = 0.96, P < 0.0001). The internal reliability of the test was also good (alpha = 0.90). Preliminary result of a factor analysis suggests that factor scores may be derived that relate to memory, language production, and knowledge of body parts. The TSI is a valid and reliable test of cognitive function in patients with severe cognitive impairment. It is appropriate to use it as a unified scale.
