Parameter estimates from latent growth curve model

Parameter Estimate (SE) Significance
Intercept 47.02 (0.74) p < .01
Intercept × child SEP −2.17 (1.11) p < .05
Intercept × adult SEP 1.95 (1.32) p = .14
Intercept × child SEP × adult SEP 3.14 (1.60) p < .05
Slope 1 4.37 (0.48) p < .01
Slope 1 × child SEP −1.53 (0.74) p < .05
Slope 1 × adult SEP 0.38 (0.94) p = .68
Slope 1 × child SEP × adult SEP 2.06 (1.29) p = .11
Slope 2 9.66 (0.75) p < .01
Slope 2 × child SEP 0.39 (1.24) p = .75
Slope 2 × adult SEP 2.31 (1.34) p < .10
Slope 2 × child SEP × adult SEP −1.98 (1.89) p = .30

SEP is coded low = 0, high = 1. LGC model is centered at age 70, Slope 1 = before 70 years, slope 2 = after 70 years.
