Comparison of comorbidity and suicidality variables between cluster B, cluster C and cluster B and C PDs (N = 94).
| Cluster B (N = 30) |
Cluster C (N = 40) |
Cluster B and C (N = 24) | Overall p-Value a |
|
|---|---|---|---|---|
| Number axis I mean (SD) | 2.2 (1.6) | 2.0 (1.4) | 2.6 (1.9) | 0.360 |
| Current mood disorder % | 57% | 55% | 73% | 0.370 |
| Current anxiety disorder % (excl. PTSD) |
40% b | 58% | 77% b | 0.030 |
| Current somatization disorder % |
13% | 10% | 10% | 0.913 |
| Dependency on alcohol and/or drugs (last 12 months) % |
37% c | 10% c | 18% | 0.021 |
| Present suicide risk medium- high % |
30% | 33% | 50% | 0.279 |
| Lifetime suicide attempt % | 53% d | 13% d | 36% | 0.001 |
Note. PDs = personality disorders; PTSD = posttraumatic stress disorder. Due to missing values, the total N varies between 91 and 94. All variables measured with the MINI-Plus 5.0.0 a, based on Welch test for ANOVA (for continuous variables) or Fisher’s exact test (for dichotomous variables). b–d Post hoc analyses to communicate significant differences in comorbidity between two groups of patients in univariate analysis, using Bonferroni corrected significance level of 0.05/3 = 0.0167.
