Abstract
When developing self-report instruments, researchers often have included both positively and negatively worded items to negate the possibility of response bias. Unfortunately, this strategy may interfere with examinations of the latent structure of self-report instruments by introducing method effects, particularly among negatively worded items. The substantive nature of the method effects remains unclear and requires examination. Building on recommendations from previous researchers (Tomás& Oliver, 1999), this study examined the longitudinal invariance of method effects associated with negatively worded items using a self-report measure of global self-esteem. Data were obtained from the National Educational Longitudinal Study (NELS; Ingels et al., 1992) across 3 waves, each separated by 2 years, and the longitudinal invariance of the method effects was tested using LISREL 8.20 with weighted least squares estimation on polychoric correlations and an asymptotic variance/covariance matrix. Our results indic...
