Note. A and E values are standardized path coefficients (all p<.05; standard errors in parentheses). M=Men; W=Women; RRS-B=Ruminative Responses Scale-Brooding; RRS-R=Ruminative Responses Scale-Reflection; RRQ-Ru=Rumination-Reflection Questionnaire-Rumination; CES-D=Center for Epidemiological Studies-Depression; MDD=Major Depressive Disorder diagnosis (lifetime); rMZ/rDZ=MZ/DZ twin correlation.
p<.05.
Statistically significant gender difference (p<.05); for the RLV, gender differences were found only in the measure specific loadings (see Figure 1).
Analyses include gender as a covariate. When using the WLSMV estimator, Mplus does not provide standard errors for standardized parameters in models with covariates.
