Table 6.
Associations between mean positive affect scores (PA), gratitude (GQ-6), self-esteem (SE), and optimism (LOT-R) and “good day” evaluations (GD), estimated using hierarchical linear modeling based on the experience sampling data collected over the course of 4 weeks (N = 65). Statistically significant results (p < .05) are highlighted in boldface. pm: person-mean centered variables; gm: grand-mean centered variables
