^bEight patients had one or more missing items on the STS-SF. Three patients lacked only one item, which was imputed using each patient’s mean STS-SF score. The remaining five lacked all items and were removed from STS-SF analyses.

^cNineteen patients had missing scores on all TRQ-SF items and were not included in any TRQ-SF analysis. One patient had only two TRQ-SF items missing, which were imputed using that patients` mean TRQ-SF score.

Note: Box-plots displaying median (Md), inter-quartile range (IQR), upper-and lower 25% of scores; outliers and extreme scores. Psychoactive substances (n = 23) Md = 3.8 (IQR = 23.1); Schizophrenia spectrum disorders (n = 11) = 18.1 (52.0); Bipolar disorder (n = 25) = 3.0 (15.7); Depressive disorders (n = 40) = 4.4 (53.2); Neurotic, stress-related and somatoform disorders (n = 25) = 3.8 (14.7); Emotionally unstable personality disorder (n = 13) = 62.0 (42.2); “Other” disorders (n = 34) = 3.9 (43.8).
