LCFA including covariates (age, sex, education) favored a two-factor and five-class solution over all other combinations of one- or two-factor solutions with any amount of classes (Table 4; bottom). The best solution is depicted in Figure 3, in which classes are ordered according to their size. Class membership was highly related to covariates. The “dependent” (3), “premorbid dependent” (2) and “senior dependent” (5) classes all had below average education according to the standardized deviation from the average (z). The “zero class” (1) and the “abuse class” (4) had average and above average education levels. The only class with a majority of females was the “zero class” (59%). The “abuse class” was older (average age 47.9 years) than the “dependence class” (average age 31.9 years).
