Note. N = 201 (between), N = 4,076 (within); → indicates regression; β parameter estimates are standardized. 95% credibility intervals of unstandardized parameter estimates are in parentheses. Bolded values indicate the credibility interval does not contain zero; BPD = borderline personality disorder; CI = credibility intervals; NA = negative affect.
