Results of fitting latent growth curve model to Functional Aging Index

Model Parameters −2 Log Likelihood LRT df change Significance
1. Base Model 16 16416.70
2. Base model + child SEP 19 16414.60 2.10 3 p = .55
3. Base model + adult SEP 19 16384.20 32.50 3 p < .01
4. Base model + child SEP and adult SEP and interactions 25 16376.00 40.70 9 p < .01

Note: LRT = Likelihood Ratio Test. Base model: age-based two-slope (+−70 years) latent growth curve model.
