Anger, hostility, and posttraumatic stress disorder in trauma-exposed adults: A meta-analysis

This meta-analysis synthesizes the available data on the strength of association between anger and posttraumatic stress disorder (PTSD) and between hostility and PTSD, covering 39 studies with trauma-exposed adults. Effect sizes did not differ for anger and hostility, which could therefore be combined; effect sizes for anger expression variables were analyzed separately. The analyses revealed large effects. The weighted mean effect size (r) was .48 for anger–hostility, .29 for anger out, .53 for anger in, and -.44 for anger control. Moderator analyses were conducted for anger–hostility, showing that effect sizes were substantially larger with increasing time since the event and that effect sizes were larger in samples with military war experience than in samples that had experienced other types of traumatic events.

Links between body mass index, total body fat, cholesterol, high-density lipoprotein, and insulin sensitivity in patients with obesity related to depression, anger, and anxiety

OBJECTIVE: Define links between psychosocial parameters and metabolic variables in obese females before and after a low-calorie diet. METHOD: Nine female obese patients (age 36.1 +/- 7.1 years, body mass index [BMI] > 30 kg/m2) were investigated before and after a 6-week low-calorie diet accompanied by behavior therapy. Blood lipids, insulin sensitivity (Bergman protocol), fat distribution (by dual-energy X-ray absorptiometry [DEXA]), as well as psychological parameters such as depression, anger, anxiety, symptom load, and well-being, were assessed before and after the dieting period. RESULTS: The females lost 9.6 +/- 2.8 kg (p < .0001) of body weight, their BMI was reduced by 3.5 +/- 0.3 kg/m2 (p < .0001), and insulin sensitivity increased from 3.0 +/- 1.8 to 4.3 +/- 1.5 mg/kg (p = .05). Their abdominal fat content decreased from 22.3 +/- 5.5 to 18.9 +/- 4.5 kg (p < .0001). In parallel, psychological parameters such as irritability (p < .05) and cognitive control (p < .0001) increased, whereas feelings of hunger (p < .05), externality (p < .05), interpersonal sensitivity (p < .01), paranoid ideation (p < .05), psychoticism (p < .01), and global severity index (p < .01) decreased. Prospectively, differences in body fat (percent) were correlated to nervousness (p < .05). Waist-to-hip ratio (WHR) differences were significantly correlated to sociability (p < .05) and inversely to emotional instability (p < .05), whereas emotional instability was inversely correlated to differences in insulin sensitivity (p < .01). DISCUSSION: Weight reduction may lead to better somatic risk factor control. Women with more nervousness and better sociability at the beginning of a diet period may lose more weight than others.

Anger and posttraumatic stress disorder symptoms in crime victims: A longitudinal analysis

Among trauma-exposed individuals, severity of posttraumatic stress disorder (PTSD) symptoms is strongly correlated with anger. The authors used 2 longitudinal data sets with 282 and 218 crime victims, respectively, to investigate the temporal sequence of anger and PTSD symptoms following the assault. Cross-lagged regression analyses indicated that PTSD symptoms predicted subsequent level of anger, but that anger did not predict subsequent PTSD symptoms. Testing alternative models (common factor model, unmeasured 3rd variable model) that might account for spuriousness of the relation strengthened confidence in the results of the cross-lagged analyses. Further analyses suggested that rumination mediates the effect of PTSD symptoms on anger.

Posttraumatic anger in crime victims: Directed at the perpetrator and at the self

This study investigated the targets of anger that are most strongly involved in posttraumatic anger. Using a sample of 218 crime victims, the authors assessed the levels of anger at potential targets (perpetrator, criminal justice system, third persons, and the self ) and their association with severity of posttraumatic stress disorder (PTSD) symptoms. The results revealed that anger was most strongly directed at the perpetrator and at the self, and that anger at other targets was low. Moreover, anger at the perpetrator and at the self showed strong associations with PTSD symptoms, whereas the associations of anger at other targets with PTSD symptoms were low.
