Notes.
a
The groups significantly differed on mean age (p < .0001), with the BPD group (M = 41.8) being significantly younger than the Non-BPD group (M = 49.2).
b
2.9% of the current sample meets criteria for BPD. This differs from the 2.7% estimated prevalence rate of BPD due to weighting of the data in order to reflect the true population.
