Supplemental materials for Fraley, Roisman, and Haltigan, "The Legacy of Early Experiences in Development: Formalizing Alternative Models of How Early Experiences are Carried Forward over Time," Developmental Psychology.

The following 7 tables report b parameter estimates for the 7 models in which freely estimating the b paths (i.e., the paths from early maternal sensitivity to subsequent outcomes) of an Enduring Effects model produced a better fit than a model in which the various b paths were constrained to be equal. All models were enduring effects models in one of several forms (e.g., a basic model including covariates, a model controlling for the on-going stability of sensitivity). The path labeled a is included for completeness. A more complete illustration of the paths and the structure of the various models are provided in Figures 2 and 4 of the article.

Parameter estimates are based on a standardized solution and were estimated using MPlus (see the article for more detail). MPlus syntax files are available from R. Chris Fraley upon request. The original correlation matrices (and means and SDs) are available in the article for investigators who are interested in exploring alternative model structures and/or parameter estimation routines.

Please see article for information regarding the children’s ages at each assessment wave (labeled Time 1 – 8, below) and the details of the specific version of each model being estimated.
