RESUMO
PURPOSE: This study examined refugees' resource needs and utilization over time, investigated the relationships between pre-displacement/socio-demographic variables and resource needs and utilization, and explored the role of resource needs and utilization on psychiatric symptom trajectories. METHODS: Iraqi refugees to the United States (N = 298) were assessed upon arrival and at 1-year intervals for 2 years for socio-demographic variables and pre-displacement trauma experiences, their need for and utilization of 14 different resources, and PTSD and depressive symptoms. RESULTS: Although refugees reported reduction of some needs over time (e.g., need for cash assistance declined from 99 to 71 %), other needs remained high (e.g., 99 % of refugees reported a need for health care at the 2-year interview). Generally, the lowest needs were reported after 2 years, and the highest utilization occurred during the first year post-arrival. Pre-displacement trauma exposure predicted high health care needs but not high health care utilization. Both high need for and use of health care predicted increasing PTSD and depressive symptoms. Specifically, increased use of psychological care across the three measurement waves predicted more PTSD and depression symptoms at the 2-year interview. CONCLUSIONS: Differences emerged between need for and actual use of resources, especially for highly trauma-exposed refugees. Resettlement agencies and assistance programs should consider the complex relationships between resource needs, resource utilization, and mental health during the early resettlement period.

Previous refugee research has been unable to link pre-displacement trauma with unemployment in the host country. The current study assessed the role of pre-displacement trauma, post-displacement trauma, and the interaction of both trauma types to prospectively examine unemployment in a random sample of newly-arrived Iraqi refugees. Participants (N = 286) were interviewed three times over the first two years post-arrival. Refugees were assessed for pre-displacement trauma exposure, post-displacement trauma exposure, a history of unemployment in the country of origin and host country, and symptoms of posttraumatic stress disorder (PTSD) and depression. Analyses found that neither pre-displacement nor post-displacement trauma independently predicted unemployment 2 years post-arrival; however, the interaction of pre and post-displacement trauma predicted 2-year unemployment. Refugees with high levels of both pre and post-displacement trauma had a 91% predicted probability of unemployment, whereas those with low levels of both traumas had a 20% predicted probability. This interaction remained significant after controlling for sociodemographic variables and mental health upon arrival to the US. Resettlement agencies and community organizations should consider the interactive effect of encountering additional trauma after escaping the hardships of the refugee's country of origin.

Research has established that trauma-related symptoms may impede the formation of a strong working alliance (i.e., interpersonal connection, trust, and shared goals between therapist and client). As the alliance is critical in trauma-focused therapy, we studied how clients' pretherapy factors, including symptoms and psychophysiological arousal, predict treatment alliance. We examined symptoms and physiological responses in 27 women who had exposure to extreme interpersonal violence; all of whom were enrolled in therapy. All had symptoms consistent with a diagnosis of posttraumatic stress disorder. Clients completed measures of working alliance and were assessed before and after treatment on measures of symptoms and autonomic arousal. Autonomic assessment included measures of skin conductance and respiratory sinus arrhythmia (RSA), taken during baseline, while viewing positive and then trauma-related slides, and during recovery. Higher alliance ratings were predicted by lower pretherapy skin conductance during trauma slides (r = -.41, p = .049) and recovery (r = -.44, p = .047) and higher RSA during baseline (r = .47, p = .027) and positive slides (r = .43, p = .044). Findings remained significant even after partialling pretherapy symptoms. These data on a high-need but understudied population suggest that sympathetic and parasympathetic arousal may help traumatized clients effectively engage in therapy, further supporting the role of parasympathetic activity in social engagement.

Rates of alcohol use disorder (AUD) are increasing among civilian and veteran populations of women in the United States, and stress pathophysiology (i.e., abnormal acute and long-term change in physiological responses to stress) is central to the maintenance of alcohol misuse within this population. Heart rate variability (HRV) is one measure of stress regulation that may help to explain the association of stress with alcohol misuse among women. In the current analysis of pilot data, 20 women veterans attended an in-person laboratory session and completed 35 daily assessments of their alcohol use and craving. During the lab session, the effects of a stress induction procedure on self-reported alcohol craving and HRV were assessed. HRV was continuously measured and indexed in the time domain, using the root mean square of successive differences between normal heartbeats (RMSSD). Alcohol craving and use during the longitudinal 35-day study period were measured via self-report questionnaires sent to participants' phones. Results indicated that resting HRV in the lab was positively associated with odds of daily craving. Moreover, HRV during the stressor, as measured in lab, was positively associated with (1) overall alcohol craving in the lab (i.e., with resting and post-stress craving), and (2) number of daily drinks during the 35-day study period. This pilot study suggests the potential role of HRV in response to stressors in predicting alcohol craving and use among female veterans. It provides pilot data for research on stress-reactive HRV as a biomarker for alcohol misuse among women, and discusses directions for future research.
RESUMO
The Critical Incident History Questionnaire indexes cumulative exposure to traumatic incidents in police by examining incident frequency and rated severity. In over 700 officers, event severity was negatively correlated (r(s) = -.61) with frequency of exposure. Cumulative exposure indices that varied emphasis on frequency and severity-using both nomothetic and idiographic methods-all showed satisfactory psychometric properties and similar correlates. All indices were only modestly related to posttraumatic stress disorder (PTSD) symptoms. Ratings of incident severity were not influenced by whether officers had ever experienced the incident. Because no index summarizing cumulative exposure to trauma had superior validity, our findings suggest that precision is not increased if frequency is weighted by severity.

A brief psychodynamic psychotherapy was assessed using the Brazilian Portuguese version of the Psychotherapy Process Q-Set (PQS). Each session was scored for its adherence to expert psychodynamic therapy (PDT) and cognitive-behavioral therapy (CBT) prototypes derived from the PQS. Results revealed that the therapy process adhered more closely to prototypical CBT than prototypical PDT. Bivariate time-series analyses showed that prototype components capturing the client's adherence to ideal CBT behaviors and collaboration between therapist and client on ideal PDT and CBT behaviors predicted therapy progress. In addition, specific client symptoms influenced whether the therapist adhered to prototypical PDT or CBT behaviors.

Relatively few studies focus on the psychological effects of trauma exposure on Asian Americans. This article presents secondary analyses of a random survey of 118 Asian American and 762 European American survivors of the 1994 Northridge, California earthquake. Asian American participants reported more psychiatric distress and were more than twice as likely to meet caseness criteria on the Brief Symptom Inventory. Ethnic differences remained after accounting for group differences in age, immigrant status, and exposure to the earthquake. Moreover, moderator analyses showed that Asian Americans were not more sensitive to these risk factors but that ethnic differences were explained by the interaction of ethnicity and having a foreign born parent. Though more work needs to be done to understand the basis of these differences, these findings challenge model minority myths about Asian American people and draw attention to their potential need for greater mental health resources following a natural disaster.

Refugees frequently experience symptoms of posttraumatic stress and depression, which impede their acculturation in the new host country where they are resettling. There are few longitudinal studies investigating predictors of mental health and acculturation during the early postmigration period. We conducted a longitudinal study of 298 Iraqi refugees, assessing them upon arrival to the U.S. and 1 year after migration. Premigration trauma was associated with increased PTSD and depressive symptoms at baseline, and with decreased acculturation 1 year later. Resilience was associated with depressive symptoms at 1-year follow-up, but not with other resettlement outcomes (PTSD symptoms, English-language skills, or acculturation). PTSD and depressive symptoms at baseline predicted the same symptoms at 1-year follow-up, but not any other resettlement outcomes. The number of chronic diseases at baseline predicted worse PTSD and depressive symptoms, acculturation, and English language skills at 1-year follow up. Postmigratory exposure to daily stressors and less social support predicted worse 1-year outcomes. Results suggest that interventions that aim to improve mental health and promote acculturation among refugees should assess their history of trauma, chronic disorders, and psychological symptoms soon after migration, and promptly provide opportunities for social support.

This meta-analysis of 58 resting baseline studies, 25 startle studies, 17 standardized trauma cue studies, and 22 idiographic trauma cue studies compared adults with and without posttraumatic stress disorder (PTSD) on psychophysiological variables: facial electromyography (EMG), heart rate (HR), skin conductance (SC), and blood pressure. Significant weighted mean effects of PTSD were observed for HR (r = .18) and SC (r = .08) in resting baseline studies; eyeblink EMG (r = .13), HR (r = .23), and SC habituation slope (r = .21) in startle studies; HR (r = .27) in standardized trauma cue studies; and frontalis EMG (r = .21), corrugator EMG (r = .34), HR (r = .22), and SC (r = .19) in idiographic trauma cue studies. The most robust correlates of PTSD were SC habituation slope, facial EMG during idiographic trauma cues, and HR during all study types. Overall, the results support the view that PTSD is associated with elevated psychophysiology. However, the generalizability of these findings is limited by characteristics of the published literature, including its disproportionate focus on male veterans and neglect of potential PTSD subtypes.

Childhood trauma may confer risk for adult psychopathology by altering emotional and physiological responses to subsequent stressors. Few studies have distinguished effects of childhood trauma from effects of current Axis I psychopathology on adult psychophysiological reactivity. The authors exposed 90 psychiatrically healthy police cadets to startling sounds under increasing threat of shock while assessing their eyeblink electromyogram (EMG), skin conductance (SC), and heart rate responses. When compared with those who did not endorse early trauma (n = 65), cadets reporting childhood trauma (n = 25) reported less positive emotion and showed greater SC responses across all threat levels. They also showed threat-dependent elevations in reported negative emotions and EMG responses. Results suggest that childhood trauma may lead to long-lasting alterations in emotional and psychophysiological reactivity even in the absence of current Axis I psychopathology.

Police officers are regularly exposed to traumatic critical incidents. The substantial mental, behavioral, and social costs of police trauma indicate a substantial need for prevention. We have refined and enhanced a previously tested Swedish program to the harsh conditions of U.S. inner cities. The program was designed to strengthen resilience during stressful encounters and teach methods of coping after exposure, thereby preventing the emergence of maladaptive symptoms and behaviors with adverse effects on professionalism. In an uncontrolled demonstration project, junior officers were trained by senior officers to engage in imaginal rehearsal of specific dangerous situations while incorporating optimal police tactics and healthy emotional reactions. A class of 32 officers in the police academy engaged in the program, and they and the trainers reported high satisfaction with it. After their first year of field work, 22 officers were reassessed. Compared to pre-training, these officers showed significant increases in the use of positive reframing and humor and significant reductions in anxiety and alcohol use over the year. Trauma symptoms did not increase. These results offer preliminary evidence for the feasibility and effectiveness of this trauma prevention program for new police officers.
RESUMO
Although kidnapping is common in war-torn countries, there is little research examining its psychological effects. Iraqi refugees (N = 298) were assessed upon arrival to the U.S. and 1 year later. At arrival, refugees were asked about prior trauma exposure, including kidnapping. One year later refugees were assessed for posttraumatic stress disorder (PTSD) and major depression disorder (MDD) using the SCID-I. Individual resilience and narratives of the kidnapping were also assessed. Twenty-six refugees (9 %) reported being kidnapped. Compared to those not kidnapped, those who were had a higher prevalence of PTSD, but not MDD, diagnoses. Analyses examining kidnapping victims revealed that higher resilience was associated with lower rates of PTSD. Narratives of the kidnapping were also discussed. This study suggests kidnapping is associated with PTSD, but not MDD. Additionally, kidnapping victims without PTSD reported higher individual resilience. Future studies should further elucidate risk and resilience mechanisms.

OBJECTIVE: Racial and ethnic disparities in posttraumatic stress disorder (PTSD) and its treatment have been documented for both civilians and military veterans. To better understand the presence of disparities and factors that might contribute to them, accurate assessment of race and ethnicity is critical; however there still remains unstandardized assessment and challenges to implementation. The authors highlight specific problems in the assessment of race and ethnicity in research, such as missing data, misclassification, classification categories too limited to reflect many peoples' social identities, and inappropriate aggregation of ethnoracial subgroups. CONCLUSIONS: A proposal is made for a minimal uniform assessment standard of race and ethnicity. Additional recommendations incorporate principles proposed by the Institute of Medicine that allow for more granular assessment of race and ethnicity to better capture individual identity and cultural factors as they relate to the assessment, experience and management of PTSD.

Though many studies have reported psychophysiological differences between individuals with and without posttraumatic stress disorder (PTSD), there have been inconsistencies in the magnitude of observed effect sizes across studies. Following a meta-analysis of the effect of current PTSD on psychophysiology during resting baseline, startle, standard trauma cue, and idiographic trauma cue studies, the author examined moderators of the obtained effect sizes. Results revealed that, among several moderators examined, greater PTSD effects on psychophysiology were most consistently associated with trauma-free control groups, greater PTSD symptom severity, and studies using earlier rather than more recent diagnostic criteria for PTSD (e.g., DSM-III versus DSM-IV).

We provide an overview of previous research conducted by our group on risk and resilience factors for PTSD symptoms in police and other first responders. Based on our work, the findings of other investigators on individual differences in risk for PTSD, and drawing on preclinical studies fear conditioning and extinction, we propose a conceptual model for the development of PTSD symptoms emphasizing the role of vulnerability and resilience to peritraumatic panic reactions. We tested this conceptual model in a cross-sectional sample of police officers (n = 715). Utilizing an hierarchical linear regression model we were able to explain 39.7% of the variance in PTSD symptoms. Five variables remained significant in the final model; greater peritraumatic distress (beta = 0.240, P < .001), greater peritraumatic dissociation (beta = 0.174, P < .001), greater problem-solving coping (beta = 0.103, P < .01), greater routine work environment stress (beta = 0.182, P < .001), and lower levels of social support (beta = -0.246, P < .001). These results were largely consistent with the proposed conceptual model. Next steps in this line of research will be to test this model prospectively in a sample of 400 police academy recruits assessed during training and currently being followed for the first 2 years of police service.

BACKGROUND: Childhood trauma is a risk factor for anxiety disorders in adulthood. One possible mechanism for this association is an increased neuroendocrine response to stress in adults with a history of childhood trauma. METHODS: In a cross-sectional study, 76 police academy recruits (mean [+/-SD] age 28 +/- 5 years, 10 female) were exposed to a video depicting real-life officers exposed to highly stressful incidents. Salivary cortisol and 3-methoxy-4-hydroxy-phenylglycol (MHPG, the major metabolite of norepinephrine) were collected at baseline, immediately after the video, and 20 min after the video. Childhood trauma before age 14 was assessed with an interview (Life Stressor Checklist-Revised). RESULTS: Exposure to the video elicited significant MHPG and cortisol responses in both groups. Recruits with childhood trauma histories (n = 16) had a significantly greater MHPG response, as evidenced by a group effect (F = 8.0, p < .01), and a group x time interaction (F = 4.1, p < .05). The cortisol response did not differ between groups. CONCLUSIONS: Police academy recruits with childhood trauma histories have an increased catecholamine response to psychological stress. This might serve as a risk factor for anxiety disorders in recruits, and these findings might generalize to other groups with a history of childhood trauma.

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.

Several studies have found that Hispanic Americans have higher rates of posttraumatic stress disorder (PTSD) than non-Hispanic Caucasian and Black Americans. The authors identified predictors of PTSD symptom severity that distinguished Hispanic police officers (n=189) from their non-Hispanic Caucasian (n=317) and Black (n=162) counterparts and modeled them to explain the elevated Hispanic risk for PTSD. The authors found that greater peritraumatic dissociation, greater wishful thinking and self-blame coping, lower social support, and greater perceived racism were important variables in explaining the elevated PTSD symptoms among Hispanics. Results are discussed in the context of Hispanic culture and may be important for prevention of mental illness in the fastest growing ethnic group in the United States.

Emotional responses (physiology, self-report, and facial expression) of 12 depressed and 10 nondepressed Spanish-speaking Latinas during sad and amusing film clips of human and animal content were compared. Depressed Latinas demonstrated less electrodermal reactivity across all the film clips and displayed fewer social smiles during the amusing-human film clip than nondepressed Latinas. No differences emerged for cardiovascular measures, reports of emotion, or facial expressions of happiness and negative emotion. Observed differences in electrodermal reactivity are similar to results from previous studies of Anglo Americans, suggesting that reduced electrodermal activity may be linked to depression across cultures. The findings also suggest that, for Latinas, depression may selectively alter expressions that serve interpersonal functions.

Trauma exposure contributes to poor mental health among refugees, and exposure often is measured using a cumulative index of items from the Harvard Trauma Questionnaire (HTQ). Few studies, however, have asked whether trauma subtypes derived from the HTQ could be superior to this cumulative index in predicting mental health outcomes. A community sample of recently arrived Iraqi refugees (N = 298) completed the HTQ and measures of posttraumatic stress disorder (PTSD) and depression symptoms. Principal components analysis of HTQ items revealed a 5-component subtype model of trauma that accounted for more item variance than a 1-component solution. These trauma subtypes also accounted for more variance in PTSD and depression symptoms (12 and 10%, respectively) than did the cumulative trauma index (7 and 3%, respectively). Trauma subtypes provided more information than cumulative trauma in the prediction of negative mental health outcomes. Therefore, use of these subtypes may enhance the utility of the HTQ when assessing at-risk populations.
