The purpose of this study was to consider the psychological meaning of the term Approving Self-Image, also known as Positive Self-Esteem (PSE). PSE and Denying Negative Self-Image (known as Negative Self-Esteem; NSE) are two factors in the Rosenberg Self-Esteem Scale (RSES). The hypothesis was that PSE would have a positive correlation with both narcissism and subjective well-being, but NSE would not. I conducted a seventy-day lagged design three-wave longitudinal online survey. A statistical analysis of data from the first wave participants (N = 400) and the results of correlational analyses supported the hypothesis. Additionally, after examining the reciprocal relationships through a multilevel analysis of the longitudinal data, I found that PSE correlates with narcissism and subjective well-being in the within model. Finally, the results from the Random Intercept Cross Lagged Parameter Model (RI-CLPM) showed that there were no causal relationships between either PSE or NSE and narcissism, but that within-person change in PSE correlated with within-person change in narcissism.
