Abstract
Purpose:
To assess the reliability and validity of a subset of the Minimum Data Set (MDS) 3.0 Section GG data elements (i.e., standardized self-care, mobility) among 147 long-stay nursing home residents in seven nursing homes in five states.
Method:
Trained clinicians assessed residents' functional abilities using select Section GG items and Section G activities of daily living items. We examined the reliability and construct validity of the data using Cronbach's alpha, correlations between Section G and Section GG items, confirmatory factor analysis (CFA), and Rasch measurement analysis.
Results:
We observed acceptable internal consistency values for all (0.98), self-care (0.93), and mobility (0.98) standardized items. Correlations between conceptually related Section G and Section GG items ranged from −0.53 to −0.84. CFA findings found acceptable values for all fit indices. Rasch analysis showed most items had acceptable fit statistics, except for the easiest and most difficult activities.
Conclusion:
These findings establish the feasibility of data collection, internal consistency reliability, and construct validity of the selected Section GG items among long-stay nursing home residents. Use of the same standardized data elements in post-acute and long-term care populations can support improved coding of function and enhance our understanding of resident functioning. [
