In a random-effects meta-analysis I found a negative association between a certain personality trait and gratitude (higher score on personality scale is associated with lower gratitude). Pearson's correlation coefficient is my effect size.
This association is significantly moderated by age. The estimate in the moderator analysis is negative.
Does this mean that the negative association between personality and gratitude gets more negative (i.e., stronger) with increasing age? Or is it getting less negative (i.e., weaker)?
The analysis was done using the robumeta package in R.
