Effects of Attribution of Responsibility for Motor Vehicle Accidents on Severity of PTSD Symptoms, Ways of Coping, and Recovery Over Six Months

In light of Delahanty et al.'s (1997) identification of attribution of responsibility for a motor vehicle accident (MVA) as a powerful determinant of initial level of distress from the trauma and of early remission of PTSD, we reexamined data from Blanchard and Hickling's (1997) prospective follow-up of 158 MVA survivors. Despite differences between the two samples (Delahanty sample recruited from hospitals 2–3 weeks post-MVA and predominantly male; our sample recruited from outpatient care 1–4 months post-MVA and predominantly female) we replicated Delahanty's findings: those with PTSD who blame themselves for the MVA are less symptomatic initially and recover more rapidly in the first 6 months than those with PTSD who blame another party for the accident.     

Posttraumatic Stress Disorder and Service Utilization Among Urban Mental Health Center Clients

Although the urban poor are at high risk for exposure to trauma, community mental health clinics rarefy diagnose clients with PTSD. Failure to diagnose PTSD may undermine the effectiveness of services provided. Our objectives were to (1) assess prevalence of traumatic experiences and PTSD, and (2) examine differences in service utilization between those who had PTSD and those who did not. Interview data were gathered from 181 urban psychiatric outpatients. A substantial number of clients had experienced at least one lifetime trauma (94%), and of those, 42% had PTSD during the past year. Analyses comparing service use between PTSD and nonPTSD clients supported our expectation that clients with PTSD would use more mental health services, and would be less satisfied with services than their nonPTSD counterparts.     

The Clinical Relevance of a Partial Remission Specifier for Posttraumatic Stress Disorder

The clinical relevance of a partial remission specifier for posttraumatic stress disorder (PTSD) was examined. Using a subgroup of outpatients from the Rhode Island Methods to Improve Diagnostic Assessment and Services project who met criteria for lifetime PTSD (N = 261), participants with current PTSD, PTSD in partial remission, and PTSD in full remission were compared on various indices of impairment. A substantial number (n = 75) of patients met criteria for PTSD in partial remission (28.7%). Outpatients in partial remission of PTSD displayed comparable levels of social and employment functioning as those with current PTSD, and over half of these patients requested treatment for their symptoms. Results support the clinical utility of a partial remission specifier for PTSD.     

Cognitive–Behavioral Treatment of Posttraumatic Stress in Patients With Implantable Cardioverter Defibrillators: Results From a Randomized Controlled Trial

Approximately 20% of patients with implantable cardioverter defibrillators (ICDs) suffer from posttraumatic stress disorder (PTSD) due to a history of cardiac arrest, device implantation, and ICD shock. There has been very little examination of treatment of PTSD symptoms in these patients. This study evaluated the effect of a specific cognitive–behavioral therapy (CBT) intervention for ICD patients with high levels of PTSD symptoms: a manualized program consisting of 8 telephone sessions with a trained counselor, a patient education book, and a stress management procedure on compact disc. Participants were 193 ICD patients, who were randomized to CBT or usual cardiac care (UCC) who completed self‐report surveys at the time of recruitment and 6 and 12 months after initial measurement. Previous publication on the primary research evaluation questions reported that the CBT condition resulted in greater improvement on PTSD and depression symptoms than the UCC for the general population of ICD patients, but did not evaluate the effect on those with elevated symptoms of PTSD. The authors conducted secondary analyses of the effect of treatment on high and low PTSD symptom groups based on a cutoff for the Impact of Event Scale‐Revised (Weiss & Marmar, 1997). Participants in the CBT group who had high symptoms experienced significantly greater symptom reduction from baseline to 12 months (d = 2.44, p = .021) than the UCC group (d = 1.12). Participants with low symptoms had small reductions regardless of group assignment (d = 0.16, p = .031). ICD‐focused CBT was sufficient to produce a large, statistically significant reduction in PTSD symptoms in ICD patients with indications for treatment.     

Acute Psychophysiological Arousal and Posttraumatic Stress Disorder: A Two-Year Prospective Study

This study investigated the role of acute arousal in the development of posttraumatic stress disorder (PTSD). Hospitalized motor vehicle accident survivors (n = 146) were assessed for acute stress disorder (ASD) within 1 month of the trauma, 6 months later, and reassessed for PTSD 2 years posttrauma (n = 87). Heart rates (HR) were assessed on the day of hospital discharge. Participants who had PTSD 2 years posttrauma had higher HR at hospital discharge than those without PTSD. A diagnosis of ASD or a resting HR of 95 beats per minute had moderate sensitivity (74%) and specificity (91%) in predicting PTSD. These findings suggest that caution is required in using acute HR as a predictor of longer-term PTSD following trauma.     

Long‐Term Trajectories of PTSD in Vietnam‐Era Veterans: The Course and Consequences of PTSD in Twins

We estimated the temporal course of posttraumatic stress disorder (PTSD) in Vietnam‐era veterans using a national sample of male twins with a 20‐year follow‐up. The complete sample included those twins with a PTSD diagnostic assessment in 1992 and who completed a DSM‐IV PTSD diagnostic assessment and a self‐report PTSD checklist in 2012 (n = 4,138). Using PTSD diagnostic data, we classified veterans into 5 mutually exclusive groups, including those who never had PTSD, and 4 PTSD trajectory groups: (a) early recovery, (b) late recovery, (c) late onset, and (d) chronic. The majority of veterans remained unaffected by PTSD throughout their lives (79.05% of those with theater service, 90.85% of those with nontheater service); however, an important minority (10.50% of theater veterans, 4.45% of nontheater veterans) in 2012 had current PTSD that was either late onset (6.55% theater, 3.29% nontheater) or chronic (3.95% theater, 1.16% nontheater). The distribution of trajectories was significantly different by theater service (p < .001). PTSD remains a prominent issue for many Vietnam‐era veterans, especially for those who served in Vietnam.     

Posttraumatic Stress Disorder in U.S. Military Primary Care: Trajectories and Predictors of One‐Year Prognosis

We examined the longitudinal course of primary care patients in the active duty Army with posttraumatic stress disorder (PTSD) and identified prognostic indicators of PTSD severity. Data were drawn from a 6‐site randomized trial of collaborative primary care for PTSD and dpression in the military. Subjects were 474 soldiers with PTSD (scores ≥ 50 on the PTSD Checklist ‐Civilian Version). Four assessments were completed at U.S. Army installations: baseline, and follow‐ups at 3 months (92.8% response rate [RR]), 6 months (90.1% RR), and 12 months (87.1% RR). Combat exposure and 7 validated indicators of baseline clinical status (alcohol misuse, depression, pain, somatic symptoms, low mental health functioning, low physical health functioning, mild traumatic brain injury) were used to predict PTSD symptom severity on the Posttraumatic Diagnostic Scale (Cronbach's α = .87, .92, .95, .95, at assessments 1–4, respectively). Growth mixture modeling identified 2 PTSD symptom trajectories: subjects reporting persistent symptoms (Persisters, 81.9%, n = 388), and subjects reporting improved symptoms (Improvers 18.1%, n = 86). Logistic regression modeling examined baseline predictors of symptom trajectories, adjusting for demographics, installation, and treatment condition. Subjects who reported moderate combat exposure, adjusted odds ratio (OR) = 0.44, 95% CI [0.20, 0.98], or who reported high exposure, OR = 0.39, 95% CI [0.17, 0.87], were less likely to be Improvers. Other baseline clinical problems were not related to symptom trajectories. Findings suggested that most military primary care patients with PTSD experience persistent symptoms, highlighting the importance of improving the effectiveness of their care. Most indicators of clinical status offered little prognostic information beyond the brief assessment of combat exposure.     

Development and persistence of posttraumatic stress disorder and the 5-HTTLPR polymorphism

Association between 5-HTTLPR polymorphism and development of acute and persistence of chronic posttraumatic stress disorder (PTSD) was prospectively investigated. DNA was extracted from 41 motor-vehicle accident victims evaluated for development and persistence of PTSD, 1 and 12 months posttrauma. At Time 1, a nonsignificant trend for higher acute PTSD rate in ll homozygotes (82%) was observed compared to those with ss and sl genotypes (50%). At Time 2, higher chronic PTSD rate was found in ll homozygotes (55%) compared to those with ss and sl genotypes (20%), with an odds ratio of 4.8 (95% CI = 1.09–21.22). Contrary to previous findings, these data are suggestive of a protective role for the s allele of 5-HTTLPR in chronic PTSD.     

The Relationship of Sleep Quality and PTSD to Anxious Reactivity from Idiographic Traumatic Event Script‐Driven Imagery

Poor sleep quality has been linked to posttraumatic stress disorder (PTSD). This study provided a test of how poor sleep quality relates to real‐time assessment of anxious reactivity to idiographic traumatic event cues. Script‐driven imagery (SDI) was employed to examine reactivity to traumatic event cues among 46 women (mean age = 27.54 years, SD = 13.62; 87% Caucasian) who had experienced either physical or sexual assault. We tested 3 hypotheses: (a) individuals with PTSD would report greater anxiety reactions to SDI than trauma‐exposed individuals without PTSD, (b) poorer sleep quality would be positively related to anxiety reactions to SDI, and (c) there would be an interaction between PTSD and sleep quality such that individuals with PTSD and relatively poor sleep quality would report greater anxious reactivity to SDI than would be expected from each main effect alone. Poor sleep quality and PTSD were related to elevated anxious reactivity to trauma cues (sr² = .06). In addition, sleep quality was negatively associated with anxious reactivity among people without PTSD (sr² =.05). The current findings, in combination with longitudinal evidence, suggest that poor sleep quality following exposure to a traumatic event may be a risk factor for anxious reactivity to traumatic event cues.     

Alcohol‐involved assault and the course of PTSD in female crime victims

Although alcohol use has been associated with increased risk of victimization, little is known about how victim substance use at the time of assault may affect posttraumatic stress disorder (PTSD) symptom development. The present study is a longitudinal examination of substance use on PTSD symptom severity and course. A community sample of female crime victims (n = 60) were assessed within 5 weeks of sexual or physical assault with 3 and 6 month postassault follow‐ups. Twenty‐three participants had consumed alcohol or alcohol/drugs prior to the assault (38%) and 37 had consumed neither alcohol nor drugs. Analyses were conducted using hierarchical linear modeling. Participants who had consumed alcohol had lower initial intrusive symptoms, but their symptoms improved less over time.     

Acute stress disorder and posttraumatic stress disorder in parents of injured children

Acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) were examined in 334 parents of children with traffic‐related injuries. In the first month after their child's injury, 12% of parents had ASD and another 25% had partial ASD. Among 251 parents assessed again approximately 6 months postinjury, 8% had PTSD and another 7% had partial PTSD. The ASD and PTSD severity were associated (r = .54), but ASD status was not a sensitive predictor of later PTSD. Independent predictors of ASD severity included prior trauma exposure, peritrauma exposure and perceptions of the child's pain and life threat, and child ASD severity. Independent predictors of PTSD severity included prior trauma exposure, parent ASD severity, and parent‐rated child physical health at follow‐up.     

Comparing Outcomes of Women‐Only and Mixed‐Gender Intensive Posttraumatic Stress Disorder Treatment for Female Veterans

Although most female veterans treated in specialized intensive Veterans Health Administration (VHA) posttraumatic stress disorder (PTSD) programs receive services in settings in which over 95% of participants are men, two programs include only women. Whether outcomes for women with PTSD are superior in women‐only programs has not been evaluated. National program evaluation data on 1,357 women veterans from 57 sites were collected at program entry and 4 months after discharge. With adjustment for differences in baseline characteristics, outcomes of women in two women‐only programs (n = 469) were compared with those from 55 mixed‐gender programs (n = 888), using mixed models with random effect for site. The primary outcome was total PTSD symptom level, with supplementary information on PTSD assessment subscales, substance use, and other outcomes. At program entry, female veterans in women‐only programs had lower scores on measures of total PTSD symptoms, p = .013, d = ?0.24, and on several subscales. Adjusting for these differences, there were no significant differences between program types in terms of PTSD total score or scores on secondary measures. In women‐only programs, veterans had longer lengths of stay and were rated by their clinicians to have a higher level of commitment to therapy at discharge. Thus, women‐only programs did not show superior outcomes; however, compared to participants in mixed‐gender programs, those in women‐only programs had longer lengths of stay, higher levels of commitment to therapy, and were more likely to participate in posttreatment outcome assessments following discharge.     

The Course and Correlates of Combat‐Related PTSD in Australian Vietnam Veterans in the Three Decades After the War

Australian male Vietnam veterans (N = 388) were assessed 22 and 36 years after their return to Australia using standardized diagnostic interviews, with added data from Army records and self‐report questionnaires. Among veterans who ever had posttraumatic stress disorder (PTSD), 50.3% had a current diagnosis at the second assessment; of those who had a current diagnosis at Wave 1, 46.9% were also current at Wave 2. Late onset occurred for 19.0% of veterans, of whom 60.8% were current at Wave 2. Multivariate analysis compared veterans with no history of PTSD (n = 231) with veterans who had ever had PTSD (n = 157) to assess risk factors for PTSD incidence; and veterans with a history, but not current PTSD (n = 78) with veterans who had current PTSD at the second assessment (n = 79) to assess risk factors for failure to remit. Incidence was associated with lower education, shorter Army training predeployment, higher combat, excess drinking, and help‐seeking after return to Australia. Prevalence was associated with having a father who saw combat in World War II, being injured in battle, having a lower intelligence test score, experiencing higher combat, and having a diagnosis of phobia at the first assessment. Only combat was common to incidence and prevalence.     

Complex PTSD in Victims Exposed to Sexual and Physical Abuse: Results from the DSM-IV Field Trial for Posttraumatic Stress Disorder

Two hundred thirty four participants in the DSM-IV Posttraumatic Stress Disorder (PTSD) Field Trial who reported sexual and/or physical abuse were evaluated. Participants were categorized according to type of abuse (physical, sexual, both), duration of abuse (acute versus chronic), and onset of abuse (early versus late). Separate logistic regression analyses examined the relationship between age of onset, duration, abuse type, and the complex PTSD (CP) lifetime diagnosis for women and men. Sexually abused women, especially those who also experienced physical abuse, had a higher risk of developing CP, although CP symptoms occurred at a high base rate among physically abused women. The theoretical implications and incremental clinical usefulness of targeting CP symptoms with abused populations are discussed.     

Randomized Controlled Trial of Online Expressive Writing to Address Readjustment Difficulties Among U.S. Afghanistan and Iraq War Veterans

We examined the efficacy of a brief, accessible, nonstigmatizing online intervention—writing expressively about transitioning to civilian life. U.S. Afghanistan and Iraq war veterans with self‐reported reintegration difficulty (N = 1,292, 39.3% female, M = 36.87, SD = 9.78 years) were randomly assigned to expressive writing (n = 508), factual control writing (n = 507), or no writing (n = 277). Using intention to treat, generalized linear mixed models demonstrated that 6‐months postintervention, veterans who wrote expressively experienced greater reductions in physical complaints, anger, and distress compared with veterans who wrote factually (ds = 0.13 to 0.20; ps < .05) and greater reductions in PTSD symptoms, distress, anger, physical complaints, and reintegration difficulty compared with veterans who did not write at all (ds = 0.22 to 0.35; ps ≤ .001). Veterans who wrote expressively also experienced greater improvement in social support compared to those who did not write (d = 0.17). Relative to both control conditions, expressive writing did not lead to improved life satisfaction. Secondary analyses also found beneficial effects of expressive writing on clinically significant distress, PTSD screening, and employment status. Online expressive writing holds promise for improving health and functioning among veterans experiencing reintegration difficulty, albeit with small effect sizes.     

Posttraumatic Stress Disorder 23 Years After the 1988 Spitak Earthquake in Armenia

This population‐based longitudinal study examined the rates and predictors of posttraumatic stress disorder (PTSD) among 725 differentially exposed survivors of the 1988 Spitak earthquake in Armenia, 23 years after the event. Participants had been previously evaluated in 1991. Evaluations included assessment of current PTSD (based on DSM‐5 criteria), and a variety of potential risk and protective factors. For the whole sample, the rate of PTSD attributed to the earthquake decreased from 48.7% in 1991 to 11.6% in 2012 (p < .001). A “dose of exposure” pattern persisted, and 15.7% of participants who were in Spitak (high exposure) and 6.6% of participants who were in Kirovagan (low exposure) during the earthquake met the criteria for PTSD (p = .003). Additionally, in 2012, another 9.9% of participants met PTSD criteria due to post‐earthquake traumas, which is a 5‐fold increase from pre‐ to postearthquake (p < . 001). Factors positively associated with PTSD included earthquake‐related job loss, exposure to post‐earthquake traumas, depression at baseline, and chronic illness since the earthquake. Factors inversely associated with PTSD included housing assistance within two years after the earthquake, support of family and/or friends, and to a lesser degree, higher education and high living standard. These variables accounted for 23.1% of the variance in current PTSD severity scores. These findings indicate that PTSD rates subside significantly after a catastrophic disaster, although earthquake‐related PTSD persists among a subgroup of exposed individuals. Predictors of PTSD identified in this study provide guidance for planning acute and longer‐term postdisaster public mental health recovery programs.     

Alcohol problems and posttraumatic stress disorder in female crime victims

Comorbidity between alcohol use and posttraumatic stress disorder (PTSD) has been well documented. However, there are few longitudinal studies with acute trauma samples. The present study examined symptoms of alcohol use disorders (AUDs) and PTSD longitudinally after assault. Female sexual (n = 69) and physical assault victims (n = 39) were assessed 2 to 4 weeks and 3 months post trauma. Women who had lifetime AUD had higher intrusive and avoidance symptoms than those who did not have AUD. Women who had any alcohol problems had higher PTSD symptoms. Participants who had alcohol problems had the same pattern of symptom recovery as those who did not have alcohol problems but remained more symptomatic over the 3 months. These findings suggest that early intervention strategies for women who have previous histories of alcohol problems and seek medical attention early post trauma may be indicated.     

Posttraumatic Stress Disorder Among Incarcerated Battered Women: A Comparison of Battered Women Who Killed Their Abusers and Those Incarcerated for Other Offenses

The present study examined differences in the amount and severity of spousal violence and posttraumatic stress symptoms between incarcerated battered women who killed/seriously assaulted their abusers and battered women incarcerated for other offenses. Additionally, several risk and buffering variables suggested by trauma research were tested to determine their ability to predict present posttraumatic stress disorder (PTSD) symptomatology. Findings revealed that battered women who killed/seriously assaulted their batterers experienced more frequent and severe spousal abuse than those in the comparison group. No significant group differences were found for present PTSD symptom levels. Predictors of present PTSD symptomatology included: childhood sexual abuse, childhood physical abuse, past PTSD symptomatology, length of time elapsed since living with partner and receiving counseling in prison. The implications of the findings are discussed.     

Posttraumatic Stress Disorder and Family Functioning in Adolescent Cancer

Twenty three adolescents with a history of cancer, 27 physically abused adolescents, and 23 healthy, nonabused adolescents were administered structured posttraumatic stress disorder (PTSD) interviews and self-report questionnaires regarding family functioning. Thirty five percent of adolescent cancer subjects met criteria for lifetime PTSD as compared to only 7% of the abused adolescents: 17% of the cancer subjects and 11% of the abuse subjects met criteria for current PTSD. Adolescents with cancer viewed their mothers and fathers as significantly more caring and more protective than the comparison and abused adolescents. Cancer subjects who met criteria for lifetime PTSD save their families as significantly more chaotic than those who did not have PTSD. Eighty three percent of cancer subjects who had lifetime PTSD also had mothers who had PTSD.     

A prospective examination of post-traumatic stress disorder in rape victims

Post-traumatic stress disorder (PTSD) and related psychopathology were examined in 95 female rape victims beginning soon after the assault (mean=12.64 days). Subjects were assessed weekly for 12 weeks. Ninety-four percent of women met symptomatic criteria for PTSD at Assessment 1, decreasing to 65% at Assessment 4 (mean=35 days postassault), and 47% at Assessment 12 (mean=94 days postassault). PTSD and related psychopathology decreased sharply between Assessments 1 and 4 for all women. Women whose PTSD persisted throughout the 3-month study did not show improvement after the fourth assessment; women who did not meet criteria for PTSD 3 months postassault showed steady improvement over time. This pattern was evidenced even after initial PTSD severity was statistically controlled. Moreover, PTSD status at 3 months postassault could be predicted with a high degree of accuracy by two brief self-report measures administered at the first assessment. The implications of the present findings and directions for future research are discussed.
