Collaborative Care for Depression and Posttraumatic Stress Disorder: Evaluation of Collaborative Care Fidelity on Symptom Trajectories and Outcomes.

BACKGROUND: Despite the growing consensus that collaborative care is effective, limited research has focused on the importance of collaborative care fidelity as it relates to mental health clinical outcomes. OBJECTIVE: To assess the relationship of collaborative care fidelity on symptom trajectories and clinical outcomes among military service members enrolled in a multi-site randomized controlled trial for the treatment of depression and posttraumatic stress disorder (PTSD). DESIGN: Study data for our analyses came from a two-parallel arm randomized trial that evaluated the effectiveness of a centralized collaborative care model compared to the existing collaborative care model for the treatment of PTSD and depression. All patients were included in the analyses to evaluate how longitudinal trajectories of PTSD and depression scores differed across various collaborative care fidelity groupings. PARTICIPANTS: A total of 666 US Military Service members screening positive for probable PTSD or depression through primary care. MAIN MEASURES: Disease registry data from a web-based clinical management support tool was used to measure collaborative care fidelity for patients enrolled in the trial. Participant depression and PTSD symptoms were collected independently from research survey assessments at four time points across the 1-year trial period. Treatment utilization records were acquired from the Military Health System administrative records to determine mental health service use. KEY RESULTS: Consistent and late fidelity to the collaborative care model predicted an improving symptom trajectory over the course of treatment. This effect was more pronounced for patients with depression than for patients with PTSD. CONCLUSIONS: Long-term fidelity to key collaborative care elements throughout care episodes may improve depression outcomes, particularly for patients with elevated symptoms. More controlled research is needed to further understand the influence of collaborative care fidelity on clinical outcomes. TRIAL REGISTRATION: Clinicaltrials.gov Identifier NCT01492348.

Mental Health Utilization Patterns During a Stepped, Collaborative Care Effectiveness Trial for PTSD and Depression in the Military Health System.

BACKGROUND: Integrated health care models aim to improve access and continuity of mental health services in general medical settings. STEPS-UP is a stepped, centrally assisted collaborative care model designed to improve posttraumatic stress disorder (PTSD) and depression care by providing the appropriate intensity and type of care based on patient characteristics and clinical complexity. STEPS-UP demonstrated improved PTSD and depression outcomes in a large effectiveness trial conducted in the Military Health System. The objective of this study was to examine differences in mental health utilization patterns between patients in the stepped, centrally assisted collaborative care model relative to patients in the collaborative care as usual-treatment arm. METHODS: Patients with probable PTSD and/or depression were recruited at 6 large military treatment facilities, and 666 patients were enrolled and randomized to STEPS-UP or usual collaborative care. Utilization data acquired from Military Health System administrative datasets were analyzed to determine mental health service use and patterns. Clinical complexity and patient characteristics were based on self-report questionnaires collected at baseline. RESULTS: Compared with the treatment as usual arm, STEPS-UP participants received significantly more mental health services and psychiatric medications across primary and specialty care settings during the year of their participation. Patterns of service use indicated that greater clinical complexity was associated with increased service use in the STEPS-UP group, but not in the usual-care group. CONCLUSIONS: Results suggest that stepped, centrally assisted collaborative care models may increase the quantity of mental health services patients receive, while efficiently matching care on the basis of the clinical complexity of patients.

Stakeholder Experiences in a Stepped Collaborative Care Study Within U.S. Army Clinics.

OBJECTIVE: This article examines stakeholder experiences with integrating treatment for posttraumatic stress disorder (PTSD) and depression within primary care clinics in the U.S. Army, the use-of-care facilitation to improve treatment, and the specific therapeutic tools used within the Stepped Treatment Enhanced PTSD Services Using Primary Care study. METHODS: We conducted a series of qualitative interviews with health care providers, care facilitators, and patients within the context of a large randomized controlled trial being conducted across 18 Army primary care clinics at 6 military installations. RESULTS: Most of stakeholders' concerns clustered around the need to improve collaborative care tools and care facilitators and providers' comfort and abilities to treat behavioral health issues in the primary care setting. CONCLUSIONS: Although stakeholders generally recognize the value of collaborative care in overcoming barriers to care, their perspectives about the utility of different tools varied. The extent to which collaborative care mechanisms are well understood, navigated, and implemented by providers, care facilitators, and patients is critical to the success of the model. Improving the design of the web-based therapy tools, increasing the frequency of team meetings and case presentations, and expanding training for primary care providers on screening and treatment for PTSD and depression and the collaborative care model's structure, processes, and offerings may improve stakeholder perceptions and usage of collaborative care.

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.

Do stigma and efficacy mediate the association between training and suicide prevention behavior among Army noncommissioned officers?

INTRODUCTION: Rates of suicide in the Active Component of the military have significantly increased since 2010, with particularly high rates among Army service members. One element of the Army's approach to suicide prevention relies on noncommissioned officers (NCOs) as gatekeepers who have regular contact with soldiers. NCOs receive suicide prevention training, but there is limited evidence that such training leads to behavior change. METHODS: We surveyed 2468 Army NCOs participating in leadership development courses to determine (a) if training on suicide prevention and soft skills (e.g., active listening) was associated with gatekeeper behavior and use of soft skills; and (b) whether that association was explained by two potential barriers, stigma and perceptions of efficacy. RESULTS: Both the number of suicide prevention training topics and soft skills trained were associated with increased gatekeeper behavior; these relationships were explained in part by lower stigma and higher efficacy for use of soft skills. The use of interactive training methods and receiving coaching after training were not associated with stigma or efficacy, though both methods were associated with more frequent use of soft skills. CONCLUSION: Results suggest that the content and format of training is important to preparing NCOs to fulfill a gatekeeper role.

The relationship between protective factors and outcomes for children exposed to violence.

To develop prevention and intervention programs for children exposed to violence, it is necessary to understand what factors might help alleviate the negative effects of violence exposure. In this study, we sought to test whether relationships exist between certain protective factors and subsequent adjustment and to examine whether violence re-exposure contributed to changes in outcomes over time. The analyses revealed that caregiver reports of both child self-control and the quality of the parent-child relationship were related to changes in child posttraumatic stress disorder (PTSD) symptoms and behavior problems. Furthermore, children experiencing more categories of violence re-exposure had increased behavior problems at follow-up compared to those without re-exposure. These findings advance our understanding of the relationship between these protective factors and outcomes for children exposed to violence and suggest that intervening to bolster these protective factors could improve outcomes.

Gender Differences in Health Among U.S. Service Members: Unwanted Gender-Based Experiences as an Explanatory Factor.

Women serving in the U.S. military are more likely to report mental health problems than men, including symptoms of depression and posttraumatic stress disorder (PTSD). Women also experience much higher rates of sexual harassment, gender discrimination, and sexual assault than men. This study examines how unwanted gender-based experiences among military service members relate to differences in health. The authors find that, once experiences of gender discrimination, sexual harassment, and sexual assault are accounted for, gender differences in health are largely attenuated. That is, the vulnerability to physical and mental health problems among female service members appears to be highly correlated with these unwanted gender-based experiences. The results highlight the possible health benefits of improved prevention of gender discrimination, sexual harassment, and sexual assault, and they indicate the need to address the mental and physical health of service members exposed to these types of experiences.

Upstream suicide prevention in the U.S. Army: Noncommissioned officers' perspectives.

The goal of this study was to examine the factors associated with Army noncommissioned officer (NCO) experiences, attitudes, and behaviors in their role of identifying potential suicide risk factors in their fellow soldiers. To better understand the perspectives of NCOs, an anonymous survey was administered to 2,468 Army NCOs. Descriptive statistics and linear regressions were conducted to compare subgroups of NCOs. Most (71%) Army NCOs have received many (11 or more) hours of suicide prevention training, but training in soft skills that may be important for the gatekeeper role was less consistently reported. Active Component soldiers reported greater confidence in their intervention skills (Cohen's d = 0.25) and fewer logistical barriers (e.g., time and space to talk) to intervening with at-risk soldiers (Cohen's d = 0.80) compared to Reserve and National Guard soldiers. Formal coursework in mental health areas like psychology or chaplaincy was associated with a greater level of confidence in intervention skills (Cohen's d = 0.23) and in more frequent intervention behavior (Cohen's d = 0.13). Army NCO trainings should be modified to better equip soldiers with the soft skills (e.g., active listening skills and verbally and nonverbally conveying nonjudgment/acceptance and empathy) needed to have effective conversations with soldiers about suicide risk factors and other sensitive topics. Strategies used within mental health education, which appears to be a strength for NCO gatekeepers, could be used to achieve this goal. Reserve and Guard NCOs may need additional supports and tailored trainings to better fit their operational context. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

A mixed-method approach to understanding the experiences of non-deployed military caregivers.

Given the unprecedented operational tempo of the Afghanistan and Iraq wars and the heavy involvement of the Reserve and National Guard, the stress that military families are exposed to is distinct from stress in earlier conflicts, with little empirical data to inform the impact on non-deployed military caregivers or "home caregivers." The study seeks to examine the experiences of home caregivers during deployments, with a focus on the impact of deployment on the caregiver's well-being. We conducted 50 qualitative interviews and 1,337 survey interviews with home caregivers who experienced at least one deployment. The structured qualitative interview focused on caregiver experiences during deployment. The quantitative data centered on caregiver well-being and household and relationship hassles. The qualitative interview notes were the unit of analysis and traditional methods were used to analyze the data. The quantitative data were analyzed using regression models. The qualitative data revealed key deployment-related household challenges that caregivers experience and the effect of those challenges on caregivers. Multivariate analyses of the quantitative data explored differences in caregivers' emotional well-being, household and relationship hassles. The results showed important component and deployment experience differences. Caregivers affiliated with the National Guard and those with more months of deployment reported significantly poorer emotional well-being, and more household and relationship hassles. Given the important role that maternal well-being has on child and family functioning, it is critical to understand how the stress of deployment is affecting mothers in their daily routines, especially during potentially high stress periods.

Back to school: review of school based interventions: comment on Rolfsness and Idsoe (2011).

We comment on a recently published article in the Journal of Traumatic Stress that reviewed school-based interventions related to trauma. We point out the recent book published by Guilford Press on the International Society for Traumatic Stress Studies Practice Guildelines (2009), which also provides a thorough review of this literature, and discuss reasons why this review may have been missed.

Effects on school outcomes in low-income minority youth: preliminary findings from a community-partnered study of a school-based trauma intervention.

OBJECTIVE: To examine academic outcomes of a community-partnered school mental health intervention for students exposed to community violence. DESIGN: Randomized controlled trial. SETTING AND PARTICIPANTS: Sixth-grade students (N = 123) from 2 middle schools in Los Angeles during the 2001-2002 academic year who had exposure to violence and posttraumatic stress symptoms in the clinical range. INTERVENTION: Students were randomized to either receive a 10-session standardized school trauma intervention (Cognitive Behavioral Intervention for Trauma in Schools) soon after screening (early intervention) or after a delay following screening (delayed intervention), but within the same school year. MAIN OUTCOME MEASURES: 59 students in the early intervention group vs. 64 students in the delayed intervention group (screened in September or December) were compared on spring semester grades in math and language arts, controlling for the students' standardized state test scores from the previous academic year and other covariates. RESULTS: Students in the early intervention group had a significantly higher spring semester mean grade in math (2.0 vs 1.6) but not language arts (2.2 vs 1.9). Students in the early intervention group were more likely than students in the delayed intervention group to have a passing grade (C or higher) in language arts (80% vs 61%; P < .033) by spring semester; we also found a substantial difference in the number of students receiving a passing math grade (70% vs 55%; P = .053). CONCLUSION: Through a collaborative partnership between school staff and researchers, preliminary evidence suggests that receiving a school trauma intervention soon after screening compared to delaying treatment can result in better school grades.

Going to Scale: Experiences Implementing a School-Based Trauma Intervention.

This article describes implementation experiences "scaling up" the Cognitive Behavioral Intervention for Trauma in Schools (CBITS)-an intervention developed using a community partnered research framework. Case studies from two sites that have successfully implemented CBITS are used to examine macro- and school-level implementation processes and strategies used to address implementation issues and create a successful implementation support system. Key elements of the implementation support system include pre-implementation work, ongoing clinical and logistical implementation supports, promotion of fidelity to the intervention's core components, tailored implementation to fit the service context, and a value on monitoring child outcomes.

Comparing the Army's Suicide Rate to the General U.S. Population: Identifying Suitable Characteristics, Data Sources, and Analytic Approaches.

Over the past 15 years, the suicide rate among members of the U.S. armed forces has doubled, with the greatest increase observed among soldiers in the Army. This increasing rate is paralleled by a smaller increase in the general U.S. population, observed across both genders, in virtually every age group and in nearly every state. An empirical question exists: What is the extent or degree to which the suicide trend in the Army is unique to that service, relative to what is observed in the general U.S. population? The Army has typically attempted to address this question by standardizing the general population to look like the Army on demographic characteristics. However, given the rise in suicide rates over the past decade, the Army wanted to better understand whether standardization based solely on age and gender is enough. Expanding the characteristics on which the general population is standardized to match the Army could be useful to gain a better understanding of the suicide trends in the Army. However, such a change also brings with it some challenges, including the lack of readily available data in the general U.S. population. In addition, even an expanded set of characteristics still results in having a large number of unmeasured factors that cannot be included in this type of analysis. In this study, the authors explore how accounting for age, gender, race/ethnicity, time, marital status, and educational attainment affects suicide rate differences between soldiers and a comparable subset of the general U.S. population.

Children's mental health care following Hurricane Katrina: a field trial of trauma-focused psychotherapies.

New Orleans school children participated in an assessment and field trial of two interventions 15 months after Hurricane Katrina. Children (N = 195) reported on hurricane exposure, lifetime trauma exposure, peer and parent support, posttraumatic stress disorder (PTSD), and depressive symptoms. Teachers reported on behavior. At baseline, 60.5% screened positive for PTSD symptoms and were offered a group intervention at school or individual treatment at a mental health clinic. Uptake of the mental health care was uneven across intervention groups, with 98% beginning the school intervention, compared to 37% beginning at the clinic. Both treatments led to significant symptom reduction of PTSD symptoms, but many still had elevated PTSD symptoms at posttreatment. Implications for future postdisaster mental health work are discussed.

Integrating Department of Defense and Department of Veterans Affairs Purchased Care: Preliminary Feasibility Assessment.

The U.S. Department of Defense (DoD) and U.S. Department of Veterans Affairs (VA) health systems provide services through a mix of direct care, delivered at government facilities, and purchased care, provided through the private sector, mainly by community-based providers who have entered into contracts with third-party administrators (TPAs). In the interest of expanding DoD-VA resource sharing that may lead to greater efficiencies and cost savings, the DoD/VA Joint Executive Committee is exploring options to integrate DoD and VA's purchased care programs. This preliminary feasibility assessment examined how an integrated approach to purchasing care could affect access, quality, and costs for beneficiaries, DoD, and VA and identified general legislative, policy, and contractual challenges to implementing an integrated purchased care program. An integrated approach to purchasing care is feasible under current legal and regulatory authorities, but policy changes may be needed-and the practicality of such an approach depends on the contract and network design. For example, legal/regulatory changes in how contracts are established would be required to achieve any real savings to the government. There are also differences in the populations served by TRICARE (DoD health care) and VA, particularly in terms of age and geographic location. Implementation would be further complicated by contractual differences in the TPA contracts for VA and DoD as they relate to network standards, provider payments, network participation requirements, and reporting requirements and incentive structures. As a result, there are significant uncertainties with respect to increased efficiency or cost savings for the government.

Perceived barriers to treatment for adolescent depression.

BACKGROUND AND OBJECTIVE: Adolescent depression is common, disabling, and is associated with academic, social, behavioral, and health consequences. Despite the availability of evidence-based depression care, few teens receive it, even when recognized by primary care clinicians. Perceived barriers such as teen worry about what others think or parent concerns about cost and access to care may contribute to low rates of care. We sought to better understand perceived barriers and their impact on service use. DESIGN: After completing an eligibility and diagnostic telephone interview, all depressed teens and a matched sample of nondepressed teens recruited from 7 primary care practices were enrolled and completed telephone interviews at baseline and 6 months (August 2005-September 2006). PARTICIPANTS: Three hundred sixty-eight adolescent patients aged 13 to 17 (184 depressed and 184 nondepressed) and 338 of their parents. MEASURES: Perceived barriers to depression care and use of services for depression (psychotherapy and antidepressant medication). RESULTS: Teens with depression were significantly more likely to perceive barriers to care compared with nondepressed teens. Parents were less likely to report barriers than their teens; perceived stigma and concern about family member response were among the significant teen barriers. Teen perceived barriers scores were negatively associated with any use of antidepressants (P < 0.01), use of antidepressants for at least 1 month (P < 0.001), and any psychotherapy or antidepressant use (P < 0.05) at 6 months. CONCLUSIONS: To improve treatment for adolescent depression, interventions should address both teen and parent perceived barriers and primary care clinicians should elicit information from both adolescents and their parents.

Mental health service utilization after physical trauma: the importance of physician referral.

BACKGROUND: Despite the availability of effective treatments for posttraumatic stress reactions after serious physical injuries, many sufferers do not use mental health services. Attempts to understand the factors that facilitate mental health service use have often focused on patient-related factors without assessing provider behavior. OBJECTIVES: To examine the relative influence of patient-related factors and physician referral on mental health service utilization among patients after a traumatic physical injury. DESIGN: A fully structured interview was administered prospectively by trained lay persons to Los Angeles Country trauma center injury patients. A total of 677 patients completed an initial interview. Of those who completed an initial interview, 70% (n = 476) completed a 6-month follow-up interview and 68% (n = 462) completed a 12-month interview. MEASURES: We examined 3 classes of patient characteristics hypothesized to be related to mental health service use: need (eg, posttraumatic stress symptoms), predisposing factors (eg, gender), and enabling resources (eg, health insurance). Additionally, we looked at physician referral to mental health treatment as a provider behavior hypothesized to predict service use. RESULTS: Age, posttraumatic stress disorder symptom severity, previous mental health treatment, and physician referral were all associated with mental health service use. Physician referral demonstrated the strongest relationship with mental health service utilization. While controlling for other factors, the odds of mental health service use were nearly 8 times higher for those respondents receiving a physician referral than for those without a referral. CONCLUSIONS: Findings highlight the importance of physician referral in facilitating access to mental health services for trauma injury survivors.

Alcohol abuse and illegal drug use among Los Angeles County trauma patients: prevalence and evaluation of single item screener.

BACKGROUND: The misuse of alcohol and illicit drugs is implicated with injury and repeat injury. Admission to a trauma center provides an opportunity to identify patients with substance use problems and initiate intervention and prevention strategies. To facilitate the identification of trauma patients with substance use problems, we studied alcohol abuse and illegal substance use patterns in a large cohort of urban trauma patients, identified correlates of alcohol abuse, and assessed the utility of a single item binge-drinking screener for identifying patients with past 12-month substance use problems. METHODS: Between February 2004 and August 2006, 677 patients from four large trauma centers in Los Angeles County were interviewed. The sample was broadly representative of the entire Los Angeles County trauma center patient population. RESULTS: Twenty-four percent of patients met criteria for alcohol abuse and 15% reported using an illegal drug other than marijuana in the past 12 months. Male gender, assaultive injury, peritrauma substance use, and history of binge drinking were prominent risk factors. A single item binge drinking screen correctly identified alcohol abuse status in 76% of all patients; the screen also performed moderately well in discriminating between those who had or had not used illegal drugs in the past 12 months, with sensitivity estimates reaching 0.79 and specificity estimates reaching 0.74. CONCLUSIONS: A large proportion of urban trauma patients abuse alcohol and use illegal drugs. Distinct sociodemographic and substance use history may indicate underlying risky behaviors. Interventions and injury prevention programs need to address these causal behaviors to reduce injury morbidity and recidivism. In the busy trauma care setting, a one-item screener could be helpful in identifying patients who would benefit from more thorough assessment and possible brief intervention.

Anxiety sensitivity and aspects of alexithymia are independently and uniquely associated with posttraumatic distress.

Using a sample of adult survivors of physical trauma requiring hospitalization (N = 677), we examined the relationship of aspects of alexithymia and anxiety sensitivity to symptoms of posttraumatic distress (PTD). At the bivariate level, both aspects of alexithymia and anxiety sensitivity were positively associated with acute PTD symptomatology, but anxiety sensitivity was more strongly related to PTD symptoms. At the multivariate level, both anxiety sensitivity and aspects of alexithymia made unique and independent contributions to both total PTD symptoms and the majority of PTD symptom clusters. At the facet level, anxiety sensitivity-physical concerns and anxiety sensitivity-psychological concerns, and the alexithymic dimension of difficulty identifying feelings, were uniquely associated with acute PTD symptoms. Findings are discussed in terms of potential clinical implications.

Youth victimization profiles and change in mental health symptoms over one year.

OBJECTIVE: To understand how youth PTSD symptoms and externalizing problems emerge and change over time for youth with different profiles of victimization, including polyvictimization. METHOD: We conducted a latent class analysis (LCA) to identify empirically derived victimization profiles in a sample of 2,776 youth who participated in an evaluation study. We then conducted growth curve analyses to determine whether these victimization profiles predicted change in the course of PTSD symptoms and externalizing problems over a 1-year time period for youth engaged in a variety of community-based services. RESULTS: The LCA revealed three profiles: a low victimization profile defined by relatively low endorsement of victimization across types; a witnessing profile defined by particularly high endorsement of witnessing violence; and a polyvictimization profile defined by high endorsement of multiple types of victimization. We found that overall, despite differing initial levels of PTSD symptoms and externalizing problems, all three groups' symptoms improved over the year, but the polyvictimization class generally showed the steepest decreases, particularly in caregiver-reported PTSD symptoms. CONCLUSION: Polyvictimized youth participating in community-based services are at increased risk for developing PTSD and externalizing problems, but symptoms appear to decrease to levels similar to other victimized youth after one year.
