Oxytocin and social anxiety: Interactions with sex hormones.

Oxytocin has been associated with anxiolytic and stress reducing effects in a number of studies. Less is known about the associations of endogenous oxytocin concentrations and their interaction with other hormones such as sex hormones in relation to self-reported anxiety levels. In this study, endogenous oxytocin and sex hormone levels were analyzed in 99 high (51 women) and 100 low (50 women) socially anxious individuals. Regression analyses showed that women with high oxytocin and estradiol levels reported a lower total Liebowitz Social Anxiety Score (LSAS) as well as a lower score on the subscale LSAS Fear. This association of hormonal interaction with social anxiety scores was significant in the subsample of high socially anxious women. In men there were no significant associations for endogenous hormones with LSAS scores. These findings suggest that in women the link between oxytocin and anxiety might be dependent on basal anxiety levels as well as on individual sex hormone levels.

A mechanism-based group-psychotherapy approach to aggressive behaviour in borderline personality disorder: findings from a cluster-randomised controlled trial.

BACKGROUND: Aggressive behaviour is a prevalent and harmful phenomenon in patients with borderline personality disorder (BPD). However, no short-term, low-cost programme exists that specifically focuses on aggression. AIMS: Attuning therapy modules to pathogenetic mechanisms that underlie reactive aggression in BPD, we composed a 6 week mechanism-based anti-aggression psychotherapy (MAAP) approach for the group setting, which we tested against a non-specific supportive psychotherapy (NSSP). METHOD: A cluster-randomised two-arm parallel-group phase II trial of N = 59 patients with BPD and overt aggressive behaviour was performed (German Registry for Clinical Trials, DRKS00009445). The primary outcome was the externally directed overt aggression score of the Modified Overt Aggression Scale (M-OAS) post-treatment (adjusted for pre-treatment overt aggression). Secondary outcomes were M-OAS irritability, M-OAS response rate and ecological momentary assessment of anger post-treatment and at 6 month follow-up, as well as M-OAS overt aggression score at follow-up. RESULTS: Although no significant difference in M-OAS overt aggression between treatments was found post-treatment (adjusted difference in mean 3.49 (95% CI -5.32 to 12.31, P = 0.22), the MAAP group showed a clinically relevant decrease in aggressive behaviour of 65% on average (versus 33% in the NSSP group), with particularly strong improvement among those with the highest baseline aggression. Most notably, significant differences in reduction in overt aggression between MAAP and NSSP were found at follow-up. CONCLUSIONS: Patients with BPD and aggressive behaviour benefited from a short group psychotherapy, with improvements particularly visible at 6 month follow-up. Further studies are required to show whether these effects are specific to MAAP.

[Impact of early life maltreatment of women on the mother-child relationship : Data from mother-child dyads from Heidelberg and Berlin]. / Einfluss früher Gewalterfahrungen von Frauen auf die Mutter-Kind-Beziehung : Daten von Heidelberger und Berliner Mutter-Kind-Dyaden.

Early life maltreatment can have severe and long-lasting consequences for the directly affected individual as well as for the next generation. Data from our research including mother-child dyads from Heidelberg and Berlin show that early life maltreatment is associated with behavioral and neural changes including personality traits and attachment style of the affected mothers that negatively affect their relationship with their child. The children of these mothers affected by early life maltreatment have an elevated risk to be maltreated and to develop mental disorders. They also show a heightened cortisol concentration and a reduced inhibition control. It seems to be of importance whether the mother has experienced early life maltreatment but is resilient, meaning that she has not developed a mental disorder (up to the time of examination) or whether in addition to the early life maltreatment she has developed a mental disorder later in life. Children of mothers with early life maltreatment and a lifetime mental disorder seem to be especially exposed to stress and show the greatest impairments and risks. Based on the existing data from our research practical and clinical implications are discussed and one possible intervention in the form of a training of mentalization competencies for parents is presented.

[Validation of a screening instrument for borderline personality disorder in adolescents and young adults - psychometric properties and association with the patient's self-esteem]. / Validierung eines Screening-Instruments zur Borderline-Persönlichkeitsstörung im Jugend- und jungen Erwachsenenalter - Gütekriterien und Zusammenhang mit dem Selbstwert der Patienten.

This investigation aimed to evaluate the German version of the BPQ as a screening instrument for borderline personality disorder (BPD) in a clinical sample. Furthermore, an association between self-esteem and BPD was examined. In a consecutive modus, 27 patients with BPD and 54 clinical controls (age range: 14 - 25 years) completed a self-report questionnaire and took part in a semi-structured interview. The German version of the BPQ revealed a high internal consistency (α = 0.95) and test-retest-reliability (r = 0.94). The criterion validity (r = 0.60) and the cut-off value (49) must be interpreted with caution due to the small sample size. BPD as well as 8 out of 9 subscales of the BPQ were significantly associated with lower self-esteem. A pre-screening using the BPQ within the clinical setting may facilitate early detection of BPD. In addition, building up self-esteem seems to be very important in the treatment of patients with BPD.
