Gender and PTSD: What can we learn from female police officers?

Studies of civilians typically find that female gender is a risk factor for posttraumatic stress disorder (PTSD). Police and military studies often find no gender differences in PTSD. We compared 157 female police officers and 124 female civilians on several variables including trauma exposure, peritraumatic emotional distress, current somatization, and cumulative PTSD symptoms. We found that despite greater exposure to assaultive violence in the officer group, female civilians reported significantly more severe PTSD symptoms. Elevated PTSD symptoms in female civilians were explained by significantly more intense peritraumatic emotional distress among female civilians. We also found that female officers showed a stronger direct relationship between peritraumatic emotional distress and current somatization. Our findings suggest that apparent gender differences in PTSD may result from differences in peritraumatic emotionality, which influence subsequent PTSD and somatization symptoms. Emotionality may be more important than biological sex in understanding gender differences in PTSD.     

PTSD symptoms predict waking salivary cortisol levels in police officers

This study examines whether pre- or post-dexamethasone salivary cortisol is related to cumulative critical incident exposure, peritraumatic responses, or post-traumatic stress disorder (PTSD) symptom severity. Thirty active duty police officers completed the study protocol, which included measures of peritraumatic emotional distress, peritraumatic dissociation, duty-related trauma exposure, and PTSD symptoms. Salivary cortisol was consolidated into three outcome variables: (1) pre-dexamethasone free cortisol levels at 1, 30, 45, and 60 min after awakening, (2) post-dexamethasone cortisol levels at the identical wake times, and (3) percentage of cortisol suppression. Control variables included age, gender, average daily alcohol use, night shift work, routine work environment stressors, and salivary dexamethasone levels. Zero order correlations showed that greater levels of PTSD symptoms, peritraumatic distress, and peritraumatic dissociation were associated with lower levels of pre-dexamethasone cortisol levels on awakening, but were not associated with the other two cortisol variables. A trend was also noted for older subjects to have lower pre-dexamethasone cortisol on awakening. When these four predictors were entered simultaneously in a regression analysis, only age and PTSD symptom severity significantly predicted pre-dexamethasone awakening cortisol levels. These results replicate previous research indicating a relationship between greater PTSD symptoms and lower levels of basal cortisol on awakening, and extend this finding to a previously unstudied non-treatment seeking population, urban police.     

Hardiness and psychological distress in a cohort of police officers

Since police officers are frequently exposed to high stress situations, individual differences in the response to stress and trauma are of interest. We examined the association of hardiness components (commitment, control and challenge) with depression, posttraumatic stress disorder (PTSD) symptoms, and symptoms of general psychological distress in police officers. The random sample included 105 officers (40 women and 65 men) from the Buffalo Cardio-Metabolic Police Stress (BCOPS) study baseline visit. Components of hardiness were measured using a 15-item hardiness scale. Depressive symptoms were measured using the Center for Epidemiological Studies Depression scale (CES-D), PTSD symptoms were measured using the impact of events scale (IES), and symptoms of general psychological distress were measured using the Brief Symptoms Inventory (BSI). Associations were assessed using linear regression analysis. Models were adjusted for age, education and marital status. Because of significant gender interactions, analyses were stratified by gender. The hardiness control dimension was significantly and negatively associated with CES-D for both genders but was not associated with IES. Hardiness commitment was significantly and negatively associated with both CES-D and IES in women. Men had negative but non-significant associations for commitment with CES-D and IES. Hardiness commitment was negatively associated with the overall BSI score for both men and women but the association was only significant for men, though the strength of the association was stronger for women. This is likely a result of the impact of the smaller sample size for women. The magnitude of gender differences in these associations shows that for depressive and PTSD symptoms, the commitment dimension of hardiness may be more protective in female police officers than in male officers.     

Gender differences in traumatic experiences and mental health in active duty soldiers redeployed from Iraq and Afghanistan

The purpose of this study was to examine gender differences in combat exposure, military sexual trauma (MST), and their associations with mental health screen results among military personnel deployed in support of the wars in Afghanistan and Iraq. Data were collected as part of a pre- and post-deployment screening program at a large Army medical treatment facility. Cases included 7251 active duty soldiers (6697 men and 554 women) who presented for their pre- and post-deployment screening from March 2006 to July 2009. Pre-deployment mental health symptoms were statistically controlled for in our analyses. We found significant gender differences in demographic variables, exposure to combat, and MST. Women reported greater exposure to MST than did men. Although men reported greater exposure to high-intensity combat experiences than women, results indicate that women are experiencing combat at higher rates than observed in prior cohorts. Men were more likely to report problem drinking, and women were more likely to report depression symptoms. There were no gender differences with respect to PTSD symptoms. Although we found few differences between women and men in the impact of combat stressors on mental health, there was a stronger association between injury and PTSD symptoms for women than for men. Our findings indicate that it would be useful for clinicians to be aware of this difference and assess for exposure to a full range of traumatic combat experiences, particularly injury, as not all types of combat experiences may be equally experienced by men and women returning from military deployments.     

Combat-related PTSD and psychosocial adjustment problems among substance abusing veterans

The purpose of this study were the following: a) to determine the prevalence of combat-related posttraumatic stress disorder (PTSD) symptoms among veterans seeking assistance at a Veterans Administration medical center substance abuse treatment facility, b) to examine the relative contribution of Vietnam war zone variables to PTSD symptom development, and c) to study psychosocial adjustment problems associated with Vietnam combat exposure and with PTSD symptoms among help-seeking substance abusing men. Of 489 male veterans presenting for treatment, 10.7% had significant Vietnam combat-related PTSD symptoms as measured by the Mississippi Scale for Combat-Related PTSD. Clinically significant PTSD symptoms occurred among 46% of the subsample of combat-exposed Vietnam veterans with substance abuse problems. Degree of combat exposure was the most important military stressor that distinguished Vietnam veterans with PTSD from those without PTSD, but the groups also differed on age of war zone duty, duration of war zone duty, and whether they were wounded. Veterans who served in Vietnam did not differ from veterans who had no war zone duty on various parameters of psychosocial adjustment. However, the subgroup of Vietnam veterans with PTSD symptoms reported significantly greater psychosocial adjustment problems than their counterparts who did not have PTSD. The deleterious effects associated with combat-related PTSD appeared to be confined to adjunctive psychiatric difficulties and unemployment and did not increase risk of arrests for antisocial conduct beyond that found for veterans without PTSD. Methodological and clinical implications of these findings are discussed.     

Smaller hippocampal volume in Dutch police officers with posttraumatic stress disorder.

BACKGROUND: Previous magnetic resonance imaging studies of posttraumatic stress disorder (PTSD) have reported smaller hippocampal volume, especially in war and sexual abuse victims. Our aim was to assess hippocampal volume in traumatized police officers with and without PTSD in the absence of alcohol abuse and moderate to severe major depression. METHODS: In a case-matched control study, 14 police officers with current PTSD and 14 traumatized police officers without lifetime PTSD were examined using magnetic resonance imaging. Three temporal lobe areas were manually segmented: hippocampus, amygdala, and parahippocampal gyrus. Volumetric analysis was used to measure gray matter, white matter, and cerebrospinal fluid. RESULTS: After controlling for total brain volume, the hippocampal volume in the PTSD group was significantly smaller in comparison with the traumatized control group (total 10.6%; left 12.6%). Volumes of amygdala, parahippocampal gyrus, gray matter, white matter, and cerebrospinal fluid were not significantly altered. A significant negative correlation was found between reexperiencing symptoms and hippocampal volume in the PTSD group. CONCLUSIONS: We confirmed previous findings of smaller hippocampal volume in PTSD in a new population made up of police officers, excluding comorbidity as a confounder. The finding of smaller hippocampal volume was specific to PTSD.     

Post-traumatic stress reactions of children and adolescents exposed to the Athens 1999 earthquake.

This study was undertaken 6-7 months after the 1999 Athens earthquake with the aim of exploring the differences in post-traumatic stress disorder (PTSD), anxiety and depression symptoms between a group of children exposed to earthquake with a group of children not exposed to it, but with both groups potentially exposed to the same levels of post-earthquake adversities. The study included 2037 children, aged 9-17 years, who were assessed with self-completed questionnaires. The directly exposed group (N=1752) had significantly higher anxiety and PTSD scores than the indirectly exposed group (N=284), but no significant group differences were found in depression scores. Girls in both groups reported significantly more PTSD, anxiety and depressive symptoms than boys. Younger children reported significantly more PTSD and anxiety symptoms than the older ones. No significant interactions were found between direct exposure to earthquake, age group and gender. The severity of PTSD symptoms was most strongly predicted by greater perceived threat during the earthquake, whereas depression was most strongly predicted by the level of post-earthquake adversity. The severity of anxiety symptoms was most strongly predicted by female gender. These findings are discussed in relation to the need for screening and intervention following earthquake events.     

Psychopathology in African Unaccompanied Refugee Minors in Austria

We assessed the prevalence of a range of psychopathology among African unaccompanied refugee minors (URMs) in Austria. Additionally, the predictive value of war exposure on PTSD symptoms was examined. Forty-one URMs were assessed with the Mini-International Neuropsychiatric Interview for children and adolescents, the Youth Self-Report, the UCLA PTSD Reaction Index and Facts About You. As expected, 56% of youth had at least one diagnosis by structured clinical interview. The most common diagnoses were adjustment disorder, PTSD and dysthymia. War affliction marginally predicted (p = 0.065) PTSD controlling for age and gender. URMs had high levels of psychopathology compared to norms. Their PTSD rates were somewhat lower than found in previous studies. We discuss methodological and substantive reasons for this finding. Future studies need to examine URMs across the entire diagnostic spectrum and employ multi-method designs to yield valid results. The psychopathology in URMs has clinical and forensic implications.     

Gender differences in the effects of deployment-related stressors and pre-deployment risk factors on the development of PTSD symptoms in National Guard Soldiers deployed to Iraq and Afghanistan

ObjectiveAlthough women in the military are exposed to combat and its aftermath, little is known about whether combat as well as pre-deployment risk/protective factors differentially predict post-deployment PTSD symptoms among women compared to men. The current study assesses the influence of combat-related stressors and pre-deployment risk/protective factors on women's risk of developing PTSD symptoms following deployment relative to men's risk.MethodParticipants were 801 US National Guard Soldiers (712 men, 89 women) deployed to Iraq or Afghanistan who completed measures of potential risk/protective factors and PTSD symptoms one month before deployment (Time 1) and measures of deployment-related stressors and PTSD symptoms about 2–3 months after returning from deployment (Time 2).ResultsMen reported greater exposure to combat situations than women, while women reported greater sexual stressors during deployment than men. Exposure to the aftermath of combat (e.g., witnessing injured/dying people) did not differ by gender. At Time 2, women reported more severe PTSD symptoms and higher rates of probable PTSD than did men. Gender remained a predictor of higher PTSD symptoms after accounting for pre-deployment symptoms, prior interpersonal victimization, and combat related stressors. Gender moderated the association between several risk factors (combat-related stressors, prior interpersonal victimization, lack of unit support and pre-deployment concerns about life/family disruptions) and post-deployment PTSD symptoms.ConclusionsElevated PTSD symptoms among female service members were not explained simply by gender differences in pre-deployment or deployment-related risk factors. Combat related stressors, prior interpersonal victimization, and pre-deployment concerns about life and family disruptions during deployment were differentially associated with greater post-deployment PTSD symptoms for women than men.     

Posttraumatic stress disorder among Hispanic Vietnam veterans

OBJECTIVE: The purpose of this study was to examine posttraumatic stress disorder (PTSD) among Hispanics who served in the Vietnam War. METHOD: The authors conducted secondary data analyses of the National Vietnam Veterans Readjustment Study, a national epidemiologic study completed in 1988 of a representative sample of veterans who served during the Vietnam era (N=1,195). RESULTS: After adjustment for premilitary and military experiences, the authors found that Hispanic, particularly Puerto Rican, Vietnam veterans had significantly more severe PTSD symptoms and a higher probability of experiencing PTSD than nonminority veterans. However, they had no greater risk for other mental disorders, and their greater risk for PTSD was not explained by acculturation. Despite their more severe symptoms, Hispanic veterans, especially Puerto Rican veterans, showed no greater functional impairment than non-Hispanic white veterans. CONCLUSIONS: Hispanic Vietnam veterans, especially Puerto Rican Vietnam veterans, have a higher risk for PTSD and experience more severe PTSD symptoms than non-Hispanic white Vietnam veterans, and these differences are not explained by exposure to stressors or acculturation. This high level of symptoms was not accompanied by substantial reduction in functioning, suggesting that the observed differences in symptom reporting may reflect features of expressive style rather than different levels of illness.     

Children's responses to a nuclear waste disaster: PTSD symptoms and outcome prediction

OBJECTIVE: To examine the psychological impact of living near a nuclear waste disaster that involved ongoing threat of radioactive contamination. METHOD: Participants were an exposed sample (residence within a 5-mile radius of the nuclear plant) of 120 children (7-15 years old) and their parents and a nonexposed comparison sample of 60 children and their parents. Parent and self-ratings of the children's psychological functioning and posttraumatic stress disorder (PTSD) symptoms were obtained, along with cognitive variables. RESULTS: Minimal differences between the 2 samples were found. In the exposed sample, stress responses for the child self-reports showed several age group by gender interactions. Girls' PTSD symptoms tended to increase with age while boys' symptoms decreased, with intrusion showing the strongest effects. While child and parent PTSD symptom ratings were correlated, children reported approximately twice as many symptoms. Cognitive understanding increased with age and was greater in boys. Exposure and parent functioning significantly predicted outcome. CONCLUSIONS: Age and gender effects after disaster might best be explored as an interaction. While disaster effects were mild, the psychological health of the parents may be an important determinant of psychological health in children in this type of disaster.     

Posttraumatic stress disorder and occupational disability in South African Security Force members

South African Security Force (SASF) members have been exposed to violence and unrest for many years. However, an alarming recent increase in retirement on psychiatric grounds has coincided with sociopolitical transformation of these services. This study investigated 124 SASF members who were medically retired as a result of posttraumatic stress disorder (PTSD). The most striking finding was the long duration of exposure to duty-related incidents (16.9 +/- 7.0 years) that preceded the onset of significant symptoms. Ninety percent (N = 112) of members displayed a negative attitude toward their work, and 54% (N = 67) believed that issues related to transformation of the services had played a significant role in their disorder. These findings suggest that posttrauma factors may be as important as pretrauma and peritrauma variables in the development of PTSD.     

Police trauma encounters: precursors of compassion fatigue

Given frequent assignments of responding to critical situations, police officers are a high-risk population for exposure to traumatic stress. It was hypothesized that types and increased frequencies of certain traumas lead to increased risk for PTSD symptoms and eventually to a state of compassion fatigue through secondary processes. Compassion fatigue was conceptualized as the cost of caring without reward or result. Results indicated that the homicide of another officer in the line of duty and dealing with victims of serious crime resulted in the greatest increased risk of trauma symptoms. Gender differences were found in trauma risk, with women officers experiencing higher risk from dealing with abused children. and male officers experiencing higher risk due to shooting incidents where officers were involved. It was concluded that increased frequency and type of traumas, especially those occurring to other co-workers and those associated with gender, may eventually lead to a secondary process of emotional compassion fatigue. Available strategies for prevention are discussed     

Exploring ambivalent rape acknowledgment and posttraumatic stress symptoms among college women who have experienced rape: What’s in a name?

The present study explored rape acknowledgment among 131 college women survivors of rape utilizing three subgroups: acknowledged rape, unacknowledged rape, and ambivalent acknowledgment. Posttraumatic stress disorder (PTSD) symptom clusters and parameters of victimization and were compared between the subgroups. Of the participants, 28.2 % were classified as ambivalent rape acknowledgment, 49.6 % as acknowledged rape, and 22.1 % as unacknowledged rape. Across all four PTSD symptom clusters, the ambivalent acknowledgment group had significantly higher PTSD symptoms than the unacknowledged group. With the exception of hyperarousal symptoms, PTSD symptoms did not differ between the acknowledged and ambivalent acknowledgment groups. With regard to potential group differences in exposure to various rape tactics (i.e., physical force, threat, incapacitation), the acknowledged group indicated (a) exposure to a greater number of rape tactics relative to the other groups, (b) higher likelihood of endorsing rape via threat than the ambivalent acknowledgment group, and (c) more frequent endorsement of forcible rape than the unacknowledged group. Results are discussed in light of screening methods to assess for PTSD symptoms among rape survivors, as well as the recent changes to the Title IX law regarding sexual misconduct reports on college campuses.     

Post-traumatic Stress and Trauma-Related Subjective Distress: Comparisons Among Hispanics,African-Americans,and Whites with Severe Mental Illness

We tested the hypothesis with a sample of community mental health clients (N?=?132) that Hispanic clients would report significantly greater post-traumatic stress symptoms than African-American or white clients when controlling for gender, psychiatric symptoms of SMI, and subjective distress from six of the most commonly reported trauma in the SMI literature. Results supported our main hypothesis: being self-identified as Hispanic was significantly associated with greater post-traumatic stress symptoms. Subjective distress from having been sexually abused along with being “Hispanic” were the only two significant variables left in the equation. Limitations of this study include its modest sample size.     

Prevalence and predictors of posttraumatic stress disorder and depressive symptoms among child survivors 1 year following the Wenchuan earthquake in China

The purpose of this study was to estimate the prevalence rates of probable posttraumatic stress disorder (PTSD) and depression and to explore potential risk factors among child and adolescent survivors 1 year following the 2008 Wenchuan earthquake. 3052 participants were administered the Child PTSD Symptom Scale, the Center for Epidemiologic Studies Depression Scale for Children, and the earthquake experience scale. Results indicated that the prevalence rates of probable PTSD and depression were 8.6 and 42.5 %, respectively. Demographic variables (i.e., age and gender) and most aspects of earthquake experiences (i.e., direct exposure, close ones’ exposure, fear for the safety of close ones, prior exposure to trauma, living location, and house damage, with the exception of type of housing) made unique contributions to PTSD and depressive symptoms. In addition, the moderating effect of gender on the relationships between age and PTSD and depressive symptoms was significant. In conclusion, depression was a more common psychological response than was PTSD among child survivors 1 year following the Wenchuan earthquake. Age and gender were risk factors for both PTSD and depressive symptoms. Furthermore, older female survivors exhibit more severe PTSD and depressive symptoms. Additionally, several aspects of earthquake experiences (i.e., direct exposure, close ones’ exposure, fear for the safety of close ones, prior exposure to trauma, living location, and house damage) was also important for the development and maintenance of PTSD and depressive symptoms.     

Gender differences in psychiatric and medical comorbidity with post-traumatic stress disorder

BackgroundPost-traumatic stress disorder (PTSD) is associated with significant personal and societal burden. The present study examines the gender-specific differences in this burden in terms of the co-occurrence of psychiatric disorders and medical conditions with PTSD in the general population of France.MethodsThe study is based on a cross-sectional general population survey of 21,879 adults. Trained interviewers used a computer-assisted telephone interviewing system to administer the Composite International Diagnostic Interview-Short Form to screen for psychiatric disorders and medical conditions in the previous 12 months.ResultsOne third of those with moderately severe PTSD (35.3%) and half of those with severe PTSD (54.2%) suffered from comorbid depression. The prevalence of anxiety disorders and substance use disorders was also greater among severe cases of PTSD. Chronic back or neck problems, frequent or severe headaches, arthritis or rheumatism and hypertension were highly prevalent among adults with PTSD. Adjusting for gender, age, education, employment and marital status, moderately severe and severe PTSD diagnoses were associated with significantly greater odds of comorbid psychiatric disorders and medical conditions. With few exceptions, the pattern of gender differences in psychiatric and medical morbidity among those with moderate or severe PTSD were similar to differences observed among those without PTSD.ConclusionsThe findings highlight the burden of co-occurring psychiatric and medical conditions among PTSD sufferers in France and suggest the need for careful consideration of comorbidity in the assessment and service planning for PTSD.     

Ethnic and racial differences in clinically relevant symptoms in active duty military personnel with posttraumatic stress disorder

Previous research has shown racial/ethnic differences in Vietnam veterans on symptoms related to posttraumatic stress disorder (PTSD). The current study explored racial/ethnic differences in PTSD symptoms and clinically relevant symptoms. Resilience and social support were tested as potential moderators of racial/ethnic differences in symptoms. The sample included 303 active duty male service members seeking treatment for PTSD. After controlling for age, education, military grade, and combat exposure, Hispanic/Latino and African American service members reported greater PTSD symptoms compared to non-Hispanic White service members. Higher alcohol consumption was endorsed by Hispanic/Latino service members compared to non-Hispanic White or African American service members, even after controlling for PTSD symptom severity. No racial/ethnic differences were found with regard to other variables. These results suggest that care should be made to thoroughly assess PTSD patients, especially those belonging to minority groups, for concurrent substance use problems that may impede treatment utilization or adherence.     

Protective factors for posttraumatic stress disorder symptoms in a prospective study of police officers

Although police officers are frequently exposed to potentially traumatic incidents, only a minority will develop chronic posttraumatic stress disorder (PTSD). Identifying and understanding protective factors could inform the development of preventive interventions; however, few studies have examined this. In the present prospective study, 233 police officers were assessed during academy training and again following 2 years of police service. Caucasian race, less previous trauma exposure, and less critical incident exposure during police service as well as greater sense of self-worth, beliefs of greater benevolence of the world, greater social support and better social adjustment, all assessed during academy training, were associated with lower PTSD symptoms after 2 years of service. Positive personality attributes assessed during training with the NEO Five-Factor Personality Inventory were not associated with lower PTSD symptoms. In a hierarchical linear regression model, only Caucasian race, lower critical incident exposure during police service, greater assumptions of benevolence of the world and better social adjustment during training remained predictive of lower PTSD symptoms after 2 years of police service. These results suggest that positive world assumptions and better social functioning during training may protect police officers from critical incident related PTSD.
