Moderated mediation with MIMIC models: SEM analysis of personal resources, perceived age-related loss, and aging satisfaction
Despite the usefulness of Multiple Indicators Multiple Causes (MIMIC) models, there has been little application of them in aging study. In this paper, we first justify the MIMIC model for personal resources using the tetrad test, and then apply this model to examine the mediation relationship between personal resources, perceived age-related loss and aging satisfaction with perceived age-related loss as the mediator and aging satisfaction as the outcome variable. Moreover, the effect of two binary moderators on the mediation effect, gender and age, are examined respectively. Results show that the MIMIC model is more appropriate than the common factor model for personal resources both substantively and statistically. The direct effect of personal resources on aging satisfaction accounts more than one third of the total effect, and the indirect effect accounts neatly two thirds of the total effect. In addition, although there is no moderated mediation effect of gender, there are significant differences between young adults and old adults on the mediation effect. Those findings support the usage of MIMIC models and call for our attention on the age differences in aging study.^
