Parameter Estimates for Latent Growth Curve Models of Income-to-Needs Ratio and Economic Pressure

Model/parameter	Estimate (SE)
Income-to-needs ratio: χ²(3) = 1.91, p = .59; CFI = 1.00; RMSEA = .00; SRMR = .01
Mean intercept	0.43 (0.01)^**
Mean slope	0.00 (0.00)
Intercept variance	0.04 (0.00)^**
Slope variance	0.00 (0.00)^*
Intercept-slope covariance	0.00 (0.00)
Residual variances	0.01 (0.00)^**
Economic pressure: χ²(3) = 4.14, p = .25; CFI = 1.00; RMSEA = .02; SRMR = .03
Mean intercept	12.96 (0.11)^**
Mean slope	−0.29 (0.06)^**
Intercept variance	10.53 (0.59)^**
Slope variance	0.29 (0.28)
Intercept-slope covariance	−0.05 (0.22)
Residual variances	6.77 (0.45)^**

Note. Unstandardized parameter estimates shown for individual growth models. Income-to-needs ratio transformed with a log transformation. Income-to-needs ratio centered at 6 months, and economic strain centered at 15 months. Residual variances of income-to-needs ratio at 6, 15, and 24 months constrained to be equal, as were residual variances of economic pressure at 6, 15, and 24 months (separately). CFI = comparative fit index; RMSEA = root mean square error of approximation; SRMR = standardized root mean residual.
