Description: Using an unattrited sample of 200 older nursing home residents, this exploratory study (1) identified stability and change patterns in individual and multiple domains of functioning among long-stayers; (2) ascertained sociodemographic, social resource, physical and mental health diagnostic, and medical condition factors associated with functional trajectories; and (3) examined the relationship of longitudinal functioning and functional health status (FHS) patterns with future mortality. In portraying FHS, multidimensional functional profiles were emphasized. FHS was operationalized by integrating MOSES (Helmes et al., 1987) data on physical health, mental health, and social functioning.

Analyses used three waves of resident-level data collected from four facilities over one year as part of the Penn State Nursing Home Project (Smyer et al., 1992). Primary data were collected regarding mortality status.

Heterogeneity was revealed on cross-sectional functional profiles among long-stayers. Cluster analysis suggested a parsimonious, useful typology. Subgroups differed on medical condition levels and dementia, and future service use and mortality.

Logistic regression, multiple regression, and longitudinal cluster analyses were used to examine functional trajectories. Logistic regression revealed predictors of short-term/long-term improvement and decline. Initial status in other functional areas generally emerged as stronger predictors of distinct change trajectories.

Future functioning in individual domains was predicted using multiple regression; findings underscored stability. The strongest predictors of future outcomes were ratings from earlier waves. Knowledge of short-term status (along with initial ratings) did not improve accuracy in predicting long-term functional status (FS), cognitive functioning (CF), and social functioning (SF). Including Wave-2 data improved accuracy in predicting Wave-3 affective domain ratings.

Longitudinal cluster analyses classified long-stayers based on dynamic trajectories for individual and multiple functional domains. Analyses accounted for impairment levels and direction and extent of change. Heterogeneity in derived trajectories (stable, improving, declining, and fluctuating patterns) was revealed. Stability was suggested for most long-stayers in FS, CF, SF, and FHS. Trajectories in affective domains of functioning reflected more variability. In assessing cluster validity, antecedents and the relationship of mortality with trajectories were examined. Support was stronger for FS, CF, SF, and FHS cluster categorization schemes; all were related to future mortality.

Study limitations and implications for research and practice were addressed.
