Models 1, 2, 3, and 4 refer to addition of independent variables: model 1 included FM as independent variable; in the model series 2, pain intensity was added; in model series 3, age and sex were introduced and also the sociodemographic variables that presented a p < 0.01 in univariate analysis; and in model series 4, psychological dimensions were added to the variables used in model series 3. Only the variable(s) that had statistically significant association(s) with the dependent variables were included in the next series model(s). Values are β.
