All scales and indices are in the disordered or impaired direction
Analyses were adjusted for clustering within units and within CNAs
The mean cluster sizes are as follows: CNA: mean cluster size is 5.57 residents (SD = 3.46); the minimum is 1 and maximum is 20
Unit cluster size: 51 units; the mean cluster (unit) size is 30.34 (SD = 9.45); the minimum is 10 and the maximum is 44
*Cognitive impairment, as measured by the CARE Diagnostic Scale, although significant at the zero-order level, was not significant in the multivariate analyses. Moreover, the cognitive disorder scale was correlated with both performance and reported ADL measures >0.50, and it was removed to avoid colinearity. The performance ADL resident assessment measure was not included in the sensitivity analysis due to colinearity with the staff-reported BADL measure
