We used Mplus Version 4 (Muthén & Muthén, 1998–2004) to estimate the model using full information maximum likelihood estimation. Missingness was less than 5% on all variables. To examine differences by family type, these analyses were conducted in a multiple-group framework, comparing four groups (i.e., European American intact families, European American stepfamilies, Mexican American intact families, Mexican American stepfamilies). Adolescent outcomes were regressed onto predictors in a path analysis framework, allowing simultaneous estimation of all paths, and making possible the equating of parallel paths from predictors to adolescent outcomes, offering a more parsimonious final model. When evaluating the fit of structural models to the data, we used the standard chi-square index of statistical fit that is routinely provided under maximum likelihood estimation of parameters. We also used two indexes of practical fit, the root mean square error of approximation (RMSEA; Browne & Cudeck, 1993) and the standardized root mean square residual (SRMR; Bentler, 1995). We chose these two indices because the RMSEA is a commonly used index based on the non-centrality parameter, while the SRMR provides an estimate of observed
