Inclusive strategy with structural equation modeling, multiple imputation, and all incomplete variables
Abstract
Even very well-designed, well-executed research can result in missing responses at any rate, particularly in survey research. This Monte Carlo study investigated the effectiveness of the inclusive strategy with incomplete data, in a structural equation modeling framework with multiple imputation. Specifically, the study examined the influence of sample size, missing rates, various missingness mechanism combinations, and the inclusive strategy on convergence failure, bias, standard error, and confidence interval coverage of parameters, and model fit. The inclusive strategy, which includes additional variables in the imputation model, was found to improve parameter estimation in most cases, particularly with the convex type of missingness and the nonignorable cases caused by MAR and the restrictive strategy. Implications and future directions are discussed.
