In all analyses, (VIPI × EAS percentile score) is kept in the ANCOVA with p = 0.03–0.002. An abbreviation with _0, _2, and _4 means zero, two, or four traits in the respective personality disorder category, and the actual cut-off values for the respective personality disorder given in ( ).
VIPI = 1(0) for the treatment group (TAU). EAS: Emotional Availability Scales. DIP-Q: DSM IV and ICD-10 Personality Questionnaire.
_a = p (VIPI × Paranoid score) < 0.05.
_b = p (VIPI × Narcissistic score) < 0.01.
_c = p (VIPI × Dependent score) < 0.01.
*p < 0.05, **p < 0.01, ***p < 0.001.
ns = not significant.
