Confirmatory Factor Analysis (CFA), Exploratory Structural Equation Modeling (ESEM), and Set-ESEM: Optimal Balance Between Goodness of Fit and Parsimony

Abstract

CFAs of multidimensional constructs often fail to meet standards of good measurement (e.g., goodness-of-fit, measurement invariance, and well-differentiated factors). Exploratory structural equation modeling (ESEM) represents a compromise between exploratory factor analysis’ (EFA) flexibility, and CFA/SEM’s rigor and parsimony, but lacks parsimony (particularly in large models) and might confound constructs that need to be kept separate. In Set-ESEM, two or more a priori sets of constructs are modeled within a single model such that cross-loadings are permissible within the same set of factors (as in Full-ESEM) but are constrained to be zero for factors in different sets (as in CFA). The different sets can reflect the same set of constructs on multiple occasions, and/or different constructs measured within the same wave. Hence, Set-ESEM that represents a middle-ground between the flexibility of traditional-ESEM (hereafter referred to as Full-ESEM) and the rigor and parsimony of CFA/SEM. Thus, the purposes of this article are to provide an overview tutorial on Set-ESEM, juxtapose it with Full-ESEM, and to illustrate its application with simulated data and diverse “real” data applications with accessible, heuristic explanations of best practice.     

Changing Rates of Suicide Ideation and Attempts Among Inuit Youth: A Gender‐Based Analysis of Risk and Protective Factors

Inuit in Canada currently suffer from one of the highest rates of suicide in the world. The objective of this study was to explore the prevalence of suicide ideations and attempts among 15–24 year olds living in Nunavik, Québec, and to explore risk and protective factors of suicide attempts as a function of gender. A cross‐sectional survey was conducted in 2004 across Nunavik. Univariate and multivariate logistic regressions were conducted. A total of 22% of young males and 39% of females adults reported past suicidal attempts. Gender differences were observed in relation to associated risk and protective factors as well as degree of exposure to risk factors. Suicide prevention must include alcohol and drug prevention programs and rehabilitation services, interventions to reduce physical and sexual violence and their long‐term impacts on Inuit youth, as well as exposure to culturally meaningful activities.     

Effects of Changing Proportions of the Sexes on Ratings of Occupational Prestige

Touhey (1974) has suggested that an influx of women into high-status, male-dominated professions will result in declining prestige and desirability for those professions. The present study attempts both a replication and an extension to examine results of changing sex ratios in low-status and female-dominated occupations. Replication of the previous finding and its predicted extension to high- status women's jobs occurred only with college sophomores; juniors and seniors generally did not respond to sex composition, although they did rate high-status men's jobs as even more prestigious with a larger proportion of women employed in the job. Results for the low-status jobs were less clear, possibly reflecting the distance of college students from such occupations. Unlike Touhey's, these results are not interpreted as predicting future occupational prestige, but only as reflecting current attitudes about women and men.
