included in the model. (Note that one-tailed tests are used since the hypothesis of an improvement in fit is being evaluated.) Finally, note that all SEM results shown are standardized and thus do not depend on how the original latent factors were identified; i.e., whether a single factor loading for each factor was fixed at one or else the factor variances were fixed at one. Nevertheless, we fixed the factor variances to be one in line with standard practice for dichotomous outcome variable factor modeling.
