Risk for domestic violence: factors associated with perpetration and victimization.

The extent and potential dangerousness of the problem of domestic violence warrants systematic screening and assessment in all mental health settings. Few empirical studies have approached the question of domestic violence with the aim of identifying risk markers, making it impossible to identify a particular characteristic or set of characteristics that can be used to identify individuals at risk for perpetrating or becoming the victims of domestic violence. However, there are a number of factors that have been identified as correlates of domestic violence that may eventually prove useful for identifying individuals at risk, but the extant literature does not provide the empirical support at this time. Because many of these correlates may be brought to the attention of mental health and medical professionals (e.g., depression, substance use/abuse, physical injuries) and given the absence of established risk factors for domestic violence, there is a need for clinicians to systematically assess for violence among all of their patients. By identifying factors that might help clinicians realize that many of their patients are at risk for domestic violence, we hope to encourage them to attend to this potentially dangerous problem. Ongoing assessment in the context of knowledge regarding correlates of domestic violence can provide important information for evaluating risk of a particular violent incident. In addition, we outline strategies for assessing violence and violence risk in both perpetrators and victims in order to assist clinicians in approaching this difficult topic in a clinical setting. A careful assessment of the potential for violence within clients' ongoing relationships is necessary for clinicians to provide appropriate clinical care.

Prevalence of personality disorders among combat veterans with posttraumatic stress disorder.

Many combat veterans with PTSD have co-occurring symptoms of other forms of psychopathology; however, there have been limited studies examining personality disorders among this population. The few extant studies typically have assessed only two or three personality disorders or examined a small sample, resulting in an incomplete picture and scope of comorbidity. This study assessed all DSM-III-R personality disorders in 107 veterans in a specialized, inpatient unit. Using the Structured Clinical Interview for DSM-III-R Personality Disorders, 79.4% of the participants were diagnosed with at least one personality disorder: 29.9% received only one diagnosis, 21.5% had two, 15.9% had three, and 12.1% had four or more. The most frequent single diagnoses were Avoidant (47.2%), Paranoid (46.2%), Obsessive-Compulsive (28.3%), and Antisocial (15.1%) personality disorders.

Cluster Analysis↗

Partners' ratings of combat veterans' PTSD symptomatology.

The current study examined the concordance of combat veterans' scores on the Mississippi Scale for Combat-Related PTSD, with scores on a parallel version of that instrument completed by partners to assess veterans' symptoms. Further, the study examined the impact of quality of the marital relationship on score concordance. Bivariate and multiple regression were used with a sample of 466 veteran-partner dyads obtained from the National Vietnam Veterans Readjustment Study. There was moderate agreement in symptom reporting between veterans and their partners and little evidence to suggest that the quality of the relationship impacted upon the association between partner and veteran scores.

The quality of the intimate relationships of male Vietnam veterans: problems associated with posttraumatic stress disorder.

This study examined the quality of the intimate relationships of male Vietnam veterans. Heterosexual couples in which the veteran had posttraumatic stress disorder (PTSD; n = 26) were compared to couples in which the veteran did not have PTSD (n = 24). Over 70% of the PTSD veterans and their partners reported clinically significant levels of relationship distress compared to only about 30% of the non-PTSD couples. Relationship difficulties appeared to encompass a wide range of areas, with PTSD veterans and their partners reporting that they had more problems in their relationships, more difficulties with intimacy, and had taken more steps toward separation and divorce than the non-PTSD veterans and their partners. The degree of relationship distress was correlated with the severity of veterans' PTSD symptoms, particularly symptoms of emotional numbing. Research and clinical implications of the results are discussed.

Analysis of Variance↗

Female partners' estimations of male veterans' combat-related PTSD severity.

This study investigated concordance between male Vietnam veterans' and their female partners' reports of veterans' posttraumatic stress disorder (PTSD) symptoms. Fifty male Vietnam combat veterans and their partners rated the severity of their own PTSD symptoms. Also, partners rated the severity of veterans' symptoms. Results indicated modest levels of agreement in reports of symptom presence/absence. Partner ratings of veterans' PTSD severity were positively correlated with veteran reports and partners' own self-reported PTSD symptoms. After controlling for veterans' self-reported symptoms, partners' symptoms significantly predicted their estimates of veterans' avoidance symptoms, but not veterans' reexperiencing or hyperarousal symptoms. Theoretical and practical implications of these findings are discussed.

Thematic resolution, PTSD, and complex PTSD: the relationship between meaning and trauma-related diagnoses.

The role of modifying schemas in trauma-focused psychotherapy has received theoretical and clinical attention. However, the relationship of schematic processing to posttraumatic stress disorder (PTSD) diagnosis has not been examined empirically. The current study-compared measures of thematic disruption among individuals with PTSD alone, PTSD with concurrent complex PTSD, and no PTSD. Eighty two participants were interviewed to assess PTSD status, complex PTSD status, traumatic life events, and trauma-related thematic processing. Results indicated that variables quantifying thematic disruption and thematic resolution significantly distinguished those individuals with concurrent PTSD plus complex PTSD from the other two groups. Exploratory analyses indicated that PTSD symptom severity and the interpersonal nature of the trauma were related to thematic disruption.

Dissociative experiences and posttraumatic stress disorder among female victims of criminal assault and rape.

This study examines the relationship between posttraumatic stress disorder (PTSD) and dissociative experiences in a sample of 158 recent female assault victims (74 rape, 84 nonsexual assault) and 46 comparison subjects who had not been assaulted within the last year. Results indicated that victims had elevated scores on Dissociative Experiences Scale (DES) as compared to the comparison subjects, but that this elevation was not as high as for other traumatized samples. The level of dissociation reported by assault victims declined significantly over the three month course of the study. DES scores were related to PTSD diagnosis and symptom severity, but only among nonsexual assault victims. In rape victims, there was no correlation between dissociation and PTSD. Recent victims with a history of childhood sexual abuse were significantly more dissociative than those who did not report such a history. These results are discussed with regard to vulnerability factors for developing PTSD subsequent to a criminal assault.

Coping strategies and posttraumatic stress disorder in female victims of sexual and nonsexual assault.

The coping behaviors and posttraumatic stress disorder (PTSD) symptoms of 215 female assault victims (103 rape victims and 112 nonsexual assault victims) were assessed within 2 weeks following the assault (Time 1), and 133 of them (62%) were followed up 3 months later (Time 2). Posttrauma symptom severity significantly decreased during the 3-month study period, but PTSD severity levels at Times 1 and 2 were highly correlated. Three coping scales were constructed on the basis of exploratory factor analyses: Mobilizing Support, Positive Distancing, and Wishful Thinking. Three months postassault, rape victims showed higher levels of wishful thinking and PTSD than nonsexual assault victims. Wishful thinking showed a positive association and positive distancing a negative association with PTSD severity, controlling for assault type, initial levels of PTSD severity, and other coping strategies. The clinical relevance of these findings is discussed.

The cycle of trauma; relationship aggression in male Vietnam veterans with symptoms of posttraumatic stress disorder.

This study examined the association between symptoms of Posttraumatic Stress Disorder (PTSD) in male Vietnam veterans and their use of aggressive behavior in relationships with intimate female partners. Fifty couples participated in the study. Veterans reported on their PTSD symptoms, and veterans and partners completed measures assessing the veterans' use of physical, verbal, and psychological aggression during the preceding year as well as measures of their own perceptions of problems in the relationship. Results indicated that PTSD symptomatology places veterans at increased risk for perpetrating relationship aggression against their partners. The association between veterans' PTSD symptoms and their use of aggression in relationships was mediated by relationship problems. Clinical implications of these findings and suggestions for future research are discussed.

Arousal, numbing, and intrusion: symptom structure of PTSD following assault.

OBJECTIVE: This study investigated hypotheses concerning the importance of symptoms of numbing in posttraumatic stress disorder (PTSD). METHODS: Symptoms of PTSD were assessed in 72 female rape victims and 86 female victims of nonsexual assault approximately 3 months after the crimes occurred. A principal-components factor analysis of subjects' symptoms was then undertaken. RESULTS: The analysis yielded three factors: arousal/avoidance, numbing, and intrusion. These were somewhat different from the symptom clusters in DSM-III-R, since effortful avoidance and numbing symptoms did not load on the same factor. Numbing symptoms appeared to be particularly important in identifying individuals with PTSD. CONCLUSIONS: The results imply that there are two patterns of posttrauma symptoms, one characterizing PTSD and the second characterizing a phobic reaction.

Perceived controllability and the development of posttraumatic stress disorder (PTSD) in crime victims.

This study evaluated the association between perception of controllability and the development of posttraumatic stress disorder (PTSD) following criminal assault. Factor analysis of a perceived controllability scale revealed three factors; perceived controllability felt during the assault, expected controllability over future assaults, and perceived controllability over aversive events more generally. Only the latter factor was associated with PTSD symptom severity. The hypothesis that perceived controllability would be negatively associated with assault severity was partially supported. Further analyses showed that the association between controllability and PTSD was not mediated or moderated by assault severity measures. The role of perceived controllability in the development of PTSD is discussed.

Treatment of posttraumatic stress disorder in rape victims: a comparison between cognitive-behavioral procedures and counseling.

Rape victims with posttraumatic stress disorder (PTSD; N = 45) were randomly assigned to one of four conditions: stress inoculation training (SIT), prolonged exposure (PE), supportive counseling (SC), or wait-list control (WL). Treatments consisted of nine biweekly 90-min individual sessions conducted by a female therapist. Measures of PTSD symptoms, rape-related distress, general anxiety, and depression were administered at pretreatment, posttreatment, and follow-up (M = 3.5 months posttreatment). All conditions produced improvement on all measures immediately post-treatment and at follow-up. However, SIT produced significantly more improvement on PTSD symptoms than did SC and WL immediately following treatment. At follow-up, PE produced superior outcome on PTSD symptoms. The implications of these findings and direction for treatment and future research are discussed.
