Table 2 Median, range, descriptive means ( M _d ) and standard deviations ( SD ) for pair-wise comparisons t0–t3

	t0		t3			Time effect

Inpatient treatment
Number of inpatient stays	1.13	1.41	0.32	0.89	47	3.85	46	<.001	0.56
Duration (days)	51.3	74.2	6.8	19.9	47	4.15	46	<.001	0.61
Number of DSM-IV TR BPD criteria met	6.4	1.2	3.2	1.9	31	8.85	30	<.001	1.59

Note. Effect sizes (Cohen’s d) are based on pair-wise descriptive statistics t0-t3 (p-values pair-wise Wilcoxon- and t-tests).
Number of suicide attempts, non-suicidal self-injury, number and days of inpatient treatment stays 12 months prior t0 is compared to 12 months prior t3 NSSI.
^aMcNemar-Test because of dichotomous variables (suicide attempt yes/no).
