Winograd et al. [29] | 50 hospitalised patients, mean age 74.8 (SD = 7.9). Tested 48 hours apart. If the patient reported or the chart indicated a change in condition, the patient was excluded. This study included 33 patients. | Pass-fail scoring system. | 0.99* | Pooled SD not provided. Baseline SD 2.1 for sample 1 (n = 146) and 1.7 for sample 2 (n = 352). Weighted average SD = 1.8. | 0.18 | 0.42 |
Winograd et al. [29] | As above. | 3 level scoring system. | 0.98# | Pooled SD not provided. Baseline SD 2.8 for sample 1 (n = 146) and 3.1 for sample 2 (n = 352). Weighted average SD = 3.0. | 0.42 | 0.97 |
Sherrington and Lord [39] | Test retest of 30 older people, mean age 81.1 years (SD = 7.5) following hip fracture (16 rehabilitation hospital inpatients and 14 community dwelling). Two assessments one day apart. | 3 level scoring system. | 0.96# (0.92 -0.98) | Test 1 SD = 2.4 and test 2 SD = 2.2. Weighted average SD = 2.3. | 0.46 | 1.07 |

Winograd et al. [29] | 31 patients, mean age 75 (SD = 6.43), selected from (1) acute medical unit inpatients that had impaired mobility and (2) acute medical and surgical inpatients aged ≥ 65 years. Two assessors independently rated each patient's performance on the PPME. | Pass-fail scoring system. | 0.99 | Pooled SD not provided. Baseline SD 2.1 for sample 1 (n = 146) and 1.7 for sample 2 (n = 352). Weighted average SD = 1.8. | 0.18 | 0.42 |
