Structural equation model testing cross-lagged associations between financial strain, home disorder, relocating, modifying the home and mobility (i.e. ability to walk and speed among those able) over 3 years in the National Health and Aging Trends Study. Solid lines indicate hypothesized reciprocal inter-relationships over time between financial strain, home disorder, relocating, modifying the home and walking ability, which were constrained to be equal across years in the structural equation model. Dashed lines indicate autoregressive associations for each variable, which were not constrained to be equal across years. Correlations between contemporaneously measured financial strain, home disorder, relocating, modifying the home and walking are not shown but were estimated in the models
