Background: Although evidence-based psychotherapies (EBPs) for posttraumatic stress disorder (PTSD) were implemented starting in 2005 in the veterans health administration (VHA), the largest national healthcare system in the U.S., the rate of initiation (uptake) and prevalence of these treatments in each calendar year have not been determined. We aimed to elucidate two metrics of EBP utilization, uptake and prevalence, following implementation.Methods: Cohort study of Iraq and Afghanistan veterans in VHA (N = 181,620) with a PTSD diagnosis and ≥1 psychotherapy-coded outpatient visit from 2001 to 2014. Using natural language processing techniques, annual and cumulative uptake and prevalence rates from 2001 to 2014 were calculated for each of the two EBPs for PTSD, cognitive processing therapy (CPT) and prolonged exposure (PE) therapy.Results: Annual uptake of CPT increased during most years, reaching a maximum of 11.1%. Annual uptake of PE showed little change until 2008 and then increased, reaching a maximum of 4.4%. The annual prevalence of CPT increased throughout the study, reaching a maximum of 14.6%. The annual prevalence of PE increased to a maximum of 5.0% in 2010, but then flattened and declined. Annual uptake of minimally adequate CPT increased a to maximum of 5% in 2014. Annual uptake of minimally adequate PE increased to a maximum of 1.2% in 2010. The cumulative prevalence of CPT was 19.9% and cumulative prevalence for PE was 7.5%.Conclusions: Access to EBPs for PTSD modestly increased for Iraq and Afghanistan veterans after nationwide implementation efforts. Further expanding the reach to veterans is critical, given low rates of minimally adequate EBPs for PTSD. [ABSTRACT FROM AUTHOR]

Abstract: This study aimed to examine the degree to which posttraumatic stress disorder (PTSD) affects the relationship between social support and psychological distress for U.S. Afghanistan/Iraq era veterans with and without co-occurring psychiatric disorders. Veterans (N=1825) were administered self-report questionnaires and a structured diagnostic interview as part of a multi-site study of post-deployment mental health through the Department of Veterans Affairs (VA) Mid-Atlantic Mental Illness Research, Education and Clinical Center (MIRECC). Main and interaction effects models assessed the association between psychological distress and social support for three comparisons conditions (Controls vs. PTSD-only, non-PTSD, and PTSD plus co-morbid diagnoses). Having PTSD was a critical factor in attenuating the strength of this association, more so than other diagnoses. Furthermore, those with PTSD plus co-morbid diagnoses did not demonstrate significantly larger attenuation in that association compared to the PTSD-only group, indicating that psychiatric comorbidity may be less important in considering the role of social support in PTSD. By understanding this relationship, new avenues for engaging and enhancing treatment outcomes related to social support for veterans of this cohort may be identified. Additional longitudinal research could help evaluate the effect of PTSD symptom clusters, social support type, and trauma exposure type on these relationships. [Copyright &y& Elsevier]

Objective: An important minority of military personnel will experience mental health problems after overseas deployments. Our study sought to describe the prevalence and correlates of postdeployment mental health problems in Canadian Forces personnel. Method: Subjects were 16 193 personnel who completed postdeployment screening after return from deployment in support of the mission in Afghanistan. Screening involved a detailed questionnaire and a 40-minute, semi-structured interview with a mental health clinician. Mental health problems were assessed using the Patient Health Questionnaire and the Posttraumatic Stress Disorder Checklist—Civilian Version. Logistic regression was used to explore independent risk factors for 1 or more of 6 postdeployment mental health problems. Results: Symptoms of 1 or more of 6 mental health problems were seen in 10.2% of people screened; the most prevalent symptoms were those of major depressive disorder (3.2%), minor depression (3.3%), and posttraumatic stress disorder (2.8%). The strongest risk factors for postdeployment mental health problems were past mental health care (adjusted odds ratio [AOR] 2.89) and heavy combat exposure (AOR 2.57 for third tertile, compared with first tertile). These risk groups might be targeted in prevention and control efforts. In contrast to findings from elsewhere, Reservist status, deployment duration, and number of previous deployments had no relation with mental health problems. Conclusions: An important minority of personnel will disclose symptoms of mental health problems during postdeployment screening. Differences in risk factors seen in different nations highlight the need for caution in applying the results of research in one population to another. [ABSTRACT FROM AUTHOR]

Objective: The deployed environment poses special challenges to the delivery of effective in-theatre mental health care. Our study sought to identify the prevalence and impact of symptoms of mental health problems in Canadian Forces (CF) personnel serving in Task Force Afghanistan; and, to determine the use of, and perceived need for, mental health services in CF personnel while deployed. Methods: Our study consisted of a cross-sectional survey of all 2779 CF personnel deployed to the province of Kandahar, Afghanistan, from February 15, 2010, to March 15, 2010. Results: An important minority (8.5%) of the 1572 respondents (response rate = 57%) exceeded civilian criteria for symptoms of acute traumatic stress, major depression, or generalized anxiety. Prevalence of these 3 mental health problems increased with higher combat exposure and location in more isolated posts. A much larger fraction (31%) reported suffering a stress, emotional, alcohol, or family problem during the deployment. Only a minority of respondents with a mental health problem (26%) were currently interested in getting help. Almost one-half of respondents with a mental health problem perceived occupational dysfunction as a result, though two-thirds of respondents with occupational dysfunction were in the group without the 3 mental health problems assessed. Conclusions: The needs base for psychosocial support extends beyond personnel who meet conventional questionnaire criteria for traumatic stress, depression, or generalized anxiety. Future research is needed to understand what precise problems are driving this larger needs base and what precise supports (clinical or nonclinical) would be most appropriate. [ABSTRACT FROM AUTHOR]
