Fig. 1.

Structural equation model at 24-month follow-up.
Note:
1. Entries marked bold are statistically significant standardized coefficients.
2. a = effect of the primary predictor on the mediator; b = effect of the mediator on the outcome; c’ = the direct effect of the primary predictor on the outcome; c = the total effect of the primary predictor on the outcome.
3. The model adjusts for potential covariates: age, gender, and primary caregiver
4. This figure only presents the unstandardized coefficients for a, b, c’, and c paths. All other unstandardized coefficients and standardized coefficients produced by the model are presented in Table 2.
