A pilot study of trauma-sensitive yoga and Breathe2Relax among service members in an intensive outpatient program.

Emerging research indicates that yoga is a promising adjunct to psychological trauma treatment. The current pilot study examined the associations between psychophysiological stress, diaphragmatic breathing (DB), and a trauma-sensitive yoga (TSY) regimen developed specifically for trauma-exposed service members in alignment with recent calls for precision in reporting therapeutic yoga protocols. Participants were 31 service members enrolled in a trauma-focused intensive outpatient program (IOP). Service members participated in a brief diaphragmatic breathing (DB) session using the Breathe2Relax (B2R) app followed by the TSY session. Heart rate (HR) and perceived stress were measured at baseline and after both the DB practice and the TSY session. We assessed Yoga and DB expectancies at baseline and post TSY. Participants also rated the acceptability and usability of the B2R app. Results of linear mixed effects regression models showed decreases in HR and perceived stress, compared to baseline, following DB (HR, b = -8.68, CI 95% = -13.34, -4.02; perceived stress, b = -1.77, CI 95% = -2.35, -1.18) and TSY (HR, b = -12.44, CI 95% = -17.15, -7.73; perceived stress b = -3.69, CI 95% = -4.29, -3.08). Higher levels of expectancies, compared to lower levels, related to stronger decreases in HR and perceived stress, particularly after TSY. Overall, participants rated the B2R usability as high; virtually all participants reported that "most would learn to use the app quickly," and 76.6% reported that they would use it frequently.

Assessing the dimensionality and construct validity of the military stigma scale across current service members.

US service members are at elevated risk for distress and suicidal behavior, compared to the general US population. However, despite the availability of evidence-based treatments, only 40% of Service members in need of mental health care seek help. One potential reason for the lower use of services is that service members experience stigma or concerns that the act of seeking mental health care from a mental health provider carries a mark of disgrace. The Military Stigma Scale (MSS) was designed to assess two theoretical dimensions of help-seeking stigma (public and self), specifically among service members. The goal of the current study was to further examine the validity of the MSS among 347 active duty service members. Examination of unidimensional, two-factor, and bifactor models revealed that a bifactor model, with a general (overall stigma), two specific factors (public and self-stigma), and one method factor (accounting for negatively worded items) provided the best fit to the data. Ancillary reliability analyses also supported the MSS measuring a broad stigma factor associated with seeking mental health care in the military. Subsequent model analyses showed that the MSS was associated with other stigma-related constructs. Overall, findings suggest that the MSS is a reliable and validated scale that can be used to assess military help-seeking stigma and to evaluate results of programs designed to reduce stigma.

Informing measurement of gender differences in suicide risk and resilience: A national study of United States military veterans.

OBJECTIVE: To inform measure selection when examining gender differences in suicide risk, this paper evaluates measure performance for a set of gender-relevant constructs and examines gender differences in mean scores. METHODS: A national sample of veterans (n = 968) who had recently attempted suicide (past 6 months) completed measures assessing life experience-, psychosocial-, and health-related constructs. A multigroup latent variable model was used to assess similarity of measurement properties between women and men. RESULTS: Metric and scalar invariance indicated that the latent variables functioned similarly between women and men. Women had higher scores on negative coping, institutional betrayal, and social rejection; men had higher scores on self-compassion, autonomy, and suicide ideation. CONCLUSIONS: Measurement properties and gender differences in mean values support the use of these measures for research on gender differences. Findings also suggest further investigation of social rejection, institutional betrayal, and negative coping among women veterans at risk for suicide.

From everyday life predictions to suicide prevention: Clinical and ethical considerations in suicide predictive analytic tools.

Advances in artificial intelligence and machine learning have fueled growing interest in the application of predictive analytics to identify high-risk suicidal patients. Such application will require the aggregation of large-scale, sensitive patient data to help inform complex and potentially stigmatizing health care decisions. This paper provides a description of how suicide prediction is uniquely difficult by comparing it to nonmedical (weather and traffic forecasting) and medical predictions (cancer and human immunodeficiency virus risk), followed by clinical and ethical challenges presented within a risk-benefit conceptual framework. Because the misidentification of suicide risk may be associated with unintended negative consequences, clinicians and policymakers need to carefully weigh the risks and benefits of using suicide predictive analytics across health care populations. Practical recommendations are provided to strengthen the protection of patient rights and enhance the clinical utility of suicide predictive analytics tools.

Gender Differences in Recovery Needs After a Suicide Attempt: A National Qualitative Study of US Military Veterans.

BACKGROUND: Appropriate after-care for the estimated 1.4 million people with nonfatal suicide attempts each year in the United States is critical, yet little research has focused on recovery needs after an attempt and whether important gender differences in those needs may exist. In this study, we examined gender differences in recovery needs after a suicide attempt among a national sample of women and men veterans. METHODS: We interviewed 25 women and 25 men veterans from Veterans Health Administration health care systems across the country. Purposive sampling was used to obtain a demographically and clinically diverse sample. Transcripts were analyzed using thematic analysis. RESULTS: Although some recovery topics were similar between genders, the participants' primary recovery needs, or goals, differed by gender. Women focused on developing connections with others and wanted to increase their self-knowledge and self-worth. Men were focused on trying to live up to their ideal selves by living and doing "right." Men also wanted to feel like they were needed by others. Both women and men also wanted to feel a stronger sense of purpose in their lives. CONCLUSIONS: Findings suggest that recovery needs among veterans after a nonfatal suicide attempt vary by gender: women may benefit more from psychoeducational approaches in group settings with other women, whereas men may benefit more from approaches that help them focus on making changes in their lives towards becoming their ideal selves.

Psychophysiology during exposure to trauma memories: Comparative effects of virtual reality and imaginal exposure for posttraumatic stress disorder.

BACKGROUND: This investigation involved an in-depth examination of psychophysiological responses during exposure to the trauma memory across 10 sessions among active duty soldiers with combat-related posttraumatic stress disorder (PTSD) treated by Prolonged Exposure (PE) or Virtual Reality Exposure (VRE). We compared psychophysiological changes, session-by-session, between VRE and traditional imaginal exposure. METHODS: Heart rate (HR), galvanic skin response (GSR), and peripheral skin temperature were collected every 5 min during exposure sessions with 61 combat veterans of Iraq/Afghanistan and compared to the PTSD Checklist (PCL-C) and Clinician-Administered PTSD Scale (CAPS) outcomes using multilevel modeling. RESULTS: Over the course of treatment, participants in the PE group had higher HR arousal compared to participants in the VRE group. With reference to GSR, in earlier sessions, participants demonstrated a within-session increase, whereas, in later sessions, participants showed a within-session habituation response. A significant interaction was found for GSR and treatment assignment for within-session change, within-person effect, predicting CAPS (d = 0.70) and PCL-C (d = 0.66) outcomes. CONCLUSION: Overall, these findings suggest that exposure to traumatic memories activates arousal across sessions, with GSR being most associated with reductions in PTSD symptoms for participants in the PE group.

Posttraumatic Stress Disorder Treatment Dropout Among Military and Veteran Populations: A Systematic Review and Meta-Analysis.

High treatment dropout rates reported in recent literature have brought into question the effectiveness of trauma-focused posttraumatic stress disorder (PTSD) treatments among military populations. The aim of the current systematic review was to evaluate PTSD treatment dropout rates among military populations by treatment type and other study-level variables. We searched four databases as well as gray literature for randomized controlled trials that evaluated evidence-based PTSD treatments in samples of active duty personnel and/or veterans. In total, 26 studies were included in this review, with a total of 2,984 participants. We analyzed dropout rates across treatment types using multivariate meta-analysis. Across all forms of treatment, the aggregated dropout rate was 24.2%. Dropout percentages based on treatment type were 27.1% for trauma-focused treatments, 16.1% for non-trauma-focused treatments, and 6.8% for waitlist groups. We found substantial heterogeneity between studies that was not explained by military status or other study-level covariates. Summary risk ratios (RRs) comparing relative dropout between treatment groups indicated that trauma-focused treatment groups had a higher risk of dropout compared to non-trauma-focused treatments, RR = 1.60. The statistical heterogeneity of within-treatment dropout risk ratios was negligible. Dropout rates among military patients receiving trauma-focused therapies were only slightly higher than those reported in the literature among civilian populations and were not explained by study-level covariates.

Establishing an Evidence Synthesis Capability For Psychological Health Topics in the Military Health System.

BACKGROUND: To promote evidence-based health care, clinical providers and decision makers rely on scientific evidence to inform best practices. Evidence synthesis (ES) is a key component of this process that serves to inform health care decisions by integrating and contextualizing research findings across studies. OBJECTIVE: This paper describes the process of establishing an ES capability in the Military Health System dedicated to psychological health topics. RESEARCH DESIGNS: The goal of establishing the current ES capability was to facilitate evidence-based decision-making among clinicians, clinic managers, research funders, and policymakers, through the production and dissemination of trustworthy ES reports. We describe how we developed this capability, provide an overview of the types of evidence syntheses products we use to respond to different stakeholders, and detail the procedures established for selecting and prioritizing synthesis topics. RESULTS: We report on the productivity, acceptability, and impact of our efforts. Our reports were used by a variety of stakeholders and working groups, briefed to major committees, included in official reports and policies, and cited in clinical practice guidelines and the peer-reviewed literature. CONCLUSIONS: Our experiences thus far suggest that the current ES capability offers a needed service within our health system. Our framework may help inform other agencies interested in developing or sponsoring a similar capability.

Present-centered therapy (PCT) for post-traumatic stress disorder (PTSD) in adults.

BACKGROUND: Present-centered therapy (PCT) is a non-trauma, manualized psychotherapy for adults with post-traumatic stress disorder (PTSD). PCT was originally designed as a treatment comparator in trials evaluating the effectiveness of trauma-focused cognitive-behavioral therapy (TF-CBT). Recent trials have indicated that PCT may be an effective treatment option for PTSD and that patients may drop out of PCT at lower rates relative to TF-CBT. OBJECTIVES: To assess the effects of PCT for adults with PTSD. Specifically, we sought to determine whether (1) PCT is more effective in alleviating symptoms relative to control conditions, (2) PCT results in similar alleviation of symptoms compared to TF-CBT, based on an a priori minimally important differences on a semi-structured interview of PTSD symptoms, and (3) PCT is associated with lower treatment dropout as compared to TF-CBT. SEARCH METHODS: We searched the Cochrane Common Mental Disorders Controlled Trials Register, the Cochrane Library, Ovid MEDLINE, Embase, PsycINFO, PubMed, and PTSDpubs (previously called the Published International Literature on Traumatic Stress (PILOTS) database) (all years to 15 February 2019 search). We also searched the World Health Organization (WHO) trials portal (ICTRP) and ClinicalTrials.gov to identify unpublished and ongoing trials. Reference lists of included studies and relevant systematic reviews were checked. Grey literature searches were also conducted to identify dissertations and theses, clinical guidelines, and regulatory agency reports. SELECTION CRITERIA: We selected all randomized clinical trials (RCTs) that recruited adults diagnosed with PTSD to evaluate PCT compared to TF-CBT or a control condition. Both individual and group PCT modalities were included. The primary outcomes of interest included reduced PTSD severity as determined by a clinician-administered measure and treatment dropout rates. DATA COLLECTION AND ANALYSIS: We complied with the Cochrane recommended standards for data screening and collection. Two review authors independently screened articles for inclusion and extracted relevant data from eligible studies, including the assessment of trial quality. Random-effects meta-analyses, subgroup analyses, and sensitivity analyses were conducted using mean differences (MD) and standardized mean differences (SMD) for continuous data or risk ratios (RR) and risk differences (RD) for dichotomous data. To conclude that PCT resulted in similar reductions in PTSD symptoms relative to TF-CBT, we required a MD of less than 10 points (to include the 95% confidence interval) on the Clinician-Administered PTSD Scale (CAPS). Five members of the review team convened to rate the quality of evidence across the primary outcomes. Any disagreements were resolved through discussion. Review authors who were investigators on any of the included trials were not involved in the qualitative or quantitative syntheses. MAIN RESULTS: We included 12 studies (n = 1837), of which, three compared PCT to a wait-list/minimal attention (WL/MA) group and 11 compared PCT to TF-CBT. PCT was more effective than WL/MA in reducing PTSD symptom severity (SMD -0.84, 95% CI -1.10 to -0.59; participants = 290; studies = 3; I² = 0%). We assessed the quality of this evidence as moderate. The results of the non-inferiority analysis comparing PCT to TF-CBT did not support PCT non-inferiority, with the 95% confidence interval surpassing the clinically meaningful cut-off (MD 6.83, 95% CI 1.90 to 11.76; 6 studies, n = 607; I² = 42%). We assessed this quality of evidence as low. CAPS differences between PCT and TF-CBT attenuated at 6-month (MD 1.59, 95% CI -0.46 to 3.63; participants = 906; studies = 6; I² = 0%) and 12-month (MD 1.22, 95% CI -2.17 to 4.61; participants = 485; studies = 3; I² = 0%) follow-up periods. To confirm the direction of the treatment effect using all eligible trials, we also evaluated PTSD SMD differences. These results were consistent with the primary MD outcomes, with meaningful effect size differences between PCT and TF-CBT at post-treatment (SMD 0.32, 95% CI 0.08 to 0.56; participants = 1129; studies = 9), but smaller effect size differences at six months (SMD 0.17, 95% CI 0.05 to 0.29; participants = 1339; studies = 9) and 12 months (SMD 0.17, 95% CI 0.03 to 0.31; participants = 728; studies = 5). PCT had approximately 14% lower treatment dropout rates compared to TF-CBT (RD -0.14, 95% CI -0.18 to -0.10; participants = 1542; studies = 10). We assessed the quality of this evidence as moderate. There was no evidence of meaningful differences on self-reported PTSD (MD 4.50, 95% CI 3.09 to 5.90; participants = 983; studies = 7) or depression symptoms (MD 1.78, 95% CI -0.23 to 3.78; participants = 705; studies = 5) post-treatment. AUTHORS' CONCLUSIONS: Moderate-quality evidence indicates that PCT is more effective in reducing PTSD severity compared to control conditions. Low quality of evidence did not support PCT as a non-inferior treatment compared to TF-CBT on clinician-rated post-treatment PTSD severity. The treatment effect differences between PCT and TF-CBT may attenuate over time. PCT participants drop out of treatment at lower rates relative to TF-CBT participants. Of note, all of the included studies were primarily designed to test the effectiveness of TF-CBT which may bias results away from PCT non-inferiority.The current systematic review provides the most rigorous evaluation to date to determine whether PCT is comparably as effective as TF-CBT. Findings are generally consistent with current clinical practice guidelines that suggest that PCT may be offered as a treatment for PTSD when TF-CBT is not available.

Typologies of Combat Exposure and Their Effects on Posttraumatic Stress Disorder and Depression Symptoms.

The present study identified distinct classes of U.S. military service members based on their combat experiences and examined mental health outcomes and longitudinal growth curves of posttraumatic stress disorder (PTSD) and depression symptoms associated with each class. Participants were 551 active duty service members who screened positive for PTSD and/or depression based on DSM-IV-TR criteria. All participants completed the Combat Experiences Scale at baseline as well as PTSD and depression measures at baseline and at 3-, 6-, and 12-month follow-ups. A latent class analysis identified four classes of service members based on their combat experiences: limited exposure, medical exposure, unit exposure, and personal exposure. Service members in the personal exposure class were characterized by a distinct mental health profile: They reported a higher level of PTSD symptoms at baseline and a higher prevalence of traumatic brain injury and PTSD diagnoses during the course of the study. The limited exposure class was more likely to receive diagnoses of depression and adjustment disorders. All classes except the medical exposure class demonstrated a slight decrease in PTSD and depression symptoms over time. However, participants in the limited exposure class had a larger decrease in PTSD and depression symptoms earlier in care but did not demonstrate superior long-term symptom improvements at 12 months compared to the other groups. These results inform PTSD development models and have implications for the screening and clinical management of combat-exposed service members.

Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Tipologías de Exposición a Combate y sus Efectos en el Trastorno de Estrés Postraumático y Síntomas Depresivos. EXPERIENCIAS TRAUMÁTICAS DE COMBATE, TEPT Y DEPRESIÓN El presente estudio identificó clases distintivas de miembros del servicio militar de los EEUU basados en sus experiencias de combate y examinó los resultados en salud mental y las curvas de crecimiento longitudinal del Trastorno de Estrés Postraumático (TEPT) y síntomas depresivos asociados con cada clase. Los participantes fueron 551 miembros en servicio activo que resultaron positivo para TEPT y/o depresión basado en los criterios DSM-IV-R. Todos los participantes completaron la Escala de Experiencias de Combate así como también medidas de TEPT y Depresión, al inicio y a los 3, 6 y 12 meses de seguimiento. Un análisis de grupos latente identificó cuatro clases de miembros del servicio basados en sus experiencias de combate: exposición limitada, exposición médica, exposición de la unidad, y exposición personal. Los miembros del servicio en el grupo de exposición personal se caracterizaron por un perfil distintivo de salud mental: Ellos reportaron, al inicio, niveles más altos de síntomas de TEPT y prevalencias más altas de diagnósticos de lesión traumática cerebral y TEPT durante el curso del estudio. El grupo de exposición limitada tuvo mayor probabilidad de recibir los diagnósticos de depresión y trastorno de adaptación. Todos los grupos, excepto el grupo de exposición médica, demostraron una leve disminución en los síntomas de TEPT y depresión con el tiempo. Sin embargo, los participantes en el grupo de exposición limitada tuvieron una disminución mayor en síntomas de TEPT y depresión al inicio de la atención, pero no demostraron una mejoría mayor de los síntomas a largo plazo a los 12 meses en comparación con los otros grupos. Estos resultados sirven de base para los modelos de desarrollo de TEPT y tienen implicaciones para la detección y manejo clínico de los miembros en servicio expuestos a combate.

Virtual reality exposure versus prolonged exposure for PTSD: Which treatment for whom?

BACKGROUND: The majority of studies comparing active psychological treatments for posttraumatic stress disorder (PTSD) do not find significant differences at posttreatment. This was the case in a recent trial examining prolonged exposure (PE) and virtual reality exposure (VRE) among active-duty soldiers with combat-related PTSD. Matching individual patients to specific treatments provides a potential avenue to improve significantly the public health impact of effective treatments for PTSD. A composite moderator approach was used to identify profiles of patients who would see superior PTSD symptom reduction in VRE or PE to inform future treatment matching. METHODS: Active duty U.S. army soldiers (N = 108) were enrolled in a randomized clinical trial comparing VRE and PE in the treatment of PTSD stemming from deployments to Iraq or Afghanistan. Eighteen baseline variables were examined to identify treatment response heterogeneity in two patient groups: those with a superior response to PE and those with a superior response to VRE. The final composite moderator comprised four of 18 baseline variables. RESULTS: Results revealed that patients who were predicted to see greater PTSD symptom reduction in VRE were likely to be younger, not taking antidepressant medication, had greater PTSD hyperarousal symptoms, and were more likely to have greater than minimal suicide risk. CONCLUSIONS: Results suggest that treatment matching based on patient profiles could meaningfully improve treatment efficacy for combat-related PTSD. Future research can build on these results to improve our understanding of how to improve treatment matching for PTSD.

The Primary Care PTSD Screen for DSM-5 (PC-PTSD-5): Development and Evaluation Within a Veteran Primary Care Sample.

BACKGROUND: Posttraumatic Stress Disorder (PTSD) is associated with increased health care utilization, medical morbidity, and tobacco and alcohol use. Consequently, screening for PTSD has become increasingly common in primary care clinics, especially in Veteran healthcare settings where trauma exposure among patients is common. OBJECTIVE: The objective of this study was to revise the Primary Care PTSD screen (PC-PTSD) to reflect the new Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria for PTSD (PC-PTSD-5) and to examine both the diagnostic accuracy and the patient acceptability of the revised measure. DESIGN: We compared the PC-PTSD-5 results with those from a brief psychiatric interview for PTSD. Participants also rated screening preferences and acceptability of the PC-PTSD-5. PARTICIPANTS: A convenience sample of 398 Veterans participated in the study (response rate = 41 %). Most of the participants were male, in their 60s, and the majority identified as non-Hispanic White. MEASURES: The PC-PTSD-5 was used as the screening measure, a modified version of the PTSD module of the MINI-International Neuropsychiatric Interview was used to diagnose DSM-5 PTSD, and five brief survey items were used to assess acceptability and preferences. KEY RESULTS: The PC-PTSD-5 demonstrated excellent diagnostic accuracy (AUC = 0.941; 95 % C.I.: 0.912- 0.969). Whereas a cut score of 3 maximized sensitivity (κ[1]) = 0.93; SE = .041; 95 % C.I.: 0.849-1.00), a cut score of 4 maximized efficiency (κ[0.5] = 0.63; SE = 0.052; 95 % C.I.: 0.527-0.731), and a cut score of 5 maximized specificity (κ[0] = 0.70; SE = 0.077; 95 % C.I.: 0.550-0.853). Patients found the screen acceptable and indicated a preference for administration by their primary care providers as opposed to by other providers or via self-report. CONCLUSIONS: The PC-PTSD-5 demonstrated strong preliminary results for diagnostic accuracy, and was broadly acceptable to patients.

The associations of opioid and benzodiazepine prescriptions with injuries among US military service members.

ABSTRACT: Given the high rates of physical trauma and pain among service members, opioid-prescribing practices and use patterns have significant implications for the well-being of service members and can affect military medicine and personnel readiness. This study measured the association between prescribed opioid and benzodiazepine medications and subsequently reported injuries (accidental, alcohol and drug related, self-inflicted, and violence related) among active duty military members. Participants were service members who entered the military between January 1, 2005, and June 30, 2010. In a nested case-control design, we compared individuals with injuries to individuals without injuries with respect to their opioid and benzodiazepine prescriptions in the 30 days before the injury of an index case. We used a multiintercept, logistic regression model to compare coefficient estimates by injury type. Overall, approximately 17% of individuals with an injury and 4% of individuals without an injury had a recorded opioid prescription. Individuals with an injury of any type had greater odds of prior exposure to opioid prescriptions than controls. Although a dose-response effect was observed for all injury types, it reached a plateau sooner for natural or environmental accidents and self-inflicted injuries relative to alcohol-related and drug-related injuries, violence-related injuries, vehicle accidents, accidental falls, and other accidents. Benzodiazepine prescriptions were found in 3.5% of individuals with an injury and 0.5% of individuals without an injury. The association between benzodiazepine prescriptions and injuries was strongest for natural and environmental accidents.

Gender differences in risk and resilience for suicidal thoughts and behaviors: A national longitudinal survey study of United States veterans with a recent suicide attempt.

BACKGROUND: This study reports on gender differences in psychosocial symptoms and suicidal thoughts and behaviors from the first longitudinal, national survey of veterans with a recent nonfatal suicide attempt to inform women-tailored suicide prevention. METHODS: We recruited all female veterans with a documented nonfatal suicide attempt between October 2018 and September 2019 and a stratified matched sample of males. Surveys were administered at baseline, month 6, and month 12; 968 veterans completed the baseline survey with valid gender data. Surveys assessed psychosocial constructs, suicidal ideation severity, and suicidal behavior. Administrative datasets provided healthcare and suicide attempt data during the one year follow up. RESULTS: Women retained higher social rejection and institutional betrayal, and lower self-compassion and autonomy than men over follow up. Higher overall self-compassion was associated with lower baseline suicide ideation for both women and men; however, this association was stronger for women (Δ = -0.19; 95 % CI = -0.31, -0.07; d = -0.15). Individuals with higher overall psychological distress had greater odds of a subsequent suicide attempt (AOR = 2.20, 95 % CI = 1.56, 3.11). Social rejection had the strongest association with worsening psychological distress, both within individuals (b = 0.18; 95 % CI = 0.14, 0.23; d = 0.23) and between individuals (b = 0.07; 95 % CI = 0.04, 0.10; d = 0.09). LIMITATIONS: Results may not generalize beyond a VHA-utilizing veteran population. CONCLUSIONS: Findings from this study inform potential therapeutic targets and topics for future research on tailoring suicide prevention for women veterans. While all veterans may need support reducing distress, women may need additional support in multiple other areas.

Evidence-based telehealth interventions for posttraumatic stress disorder, depression, and anxiety: A systematic review and meta-analysis.

INTRODUCTION: The goal of this systematic review was to examine the efficacy of behavioral health care treatments for posttraumatic stress disorder (PTSD), depression, and anxiety delivered via telehealth. METHODS: We searched a combination of keywords related to telehealth, relevant mental health disorders, and evidence-based psychotherapies in three databases (PubMed, PsycInfo, and Embase) from database inception to April 2022. We included randomized controlled trials published in English wherein at least one arm received an evidence-based psychotherapy via telehealth. To be included, studies also had to enroll an adult population with symptoms or diagnosis of PTSD, depressive disorder, or anxiety disorder. RESULTS: Moderate quality of evidence was consistent with only small differences, if any, in efficacy between video teleconferencing (VTC) and in-person delivery for patients with PTSD (d = 0.06, 95% CI -0.17, 0.28). However, for those with depression, in-person delivery was associated with better outcomes compared to VTC (d = 0.28, 95% CI 0.03, 0.54; low quality of evidence). We also found that evidence-based treatments delivered over telephone were more efficacious for depression compared to treatment as usual (d = -0.47, 95% CI -0.66, -0.28; very low quality of evidence). Very low quality of evidence supported the use of telehealth versus waitlist for anxiety (d = -0.48, 95% CI -0.89, -0.09). CONCLUSIONS: A synthesis across 29 studies indicates that the efficacy of telehealth for delivery of evidence-based behavioral health interventions varies by target diagnosis and telehealth modality. More research is needed on the efficacy of telehealth treatments for depression and anxiety.

Disparate rates of new-onset depression during the menopausal transition in 2 community-based populations: real, or really wrong?

This study took place in eastern Massachusetts and included respondents from the Harvard Study of Moods and Cycles Cohort 1, enrolled between 1995 and 1997, and the Harvard Study of Moods and Cycles Cohort 2, enrolled between 2005 and 2009. In prospectively assessing rates of new-onset depression in 2 populations of late-reproductive-aged women with no Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) lifetime history of depression, we were surprised to find far lower rates of depression in the population with greater racial diversity and lower socioeconomic status, contrary to what had been reported in the scientific literature. To better understand why these disparate results occurred, we assessed confounding and outcome misclassification as potential explanations for the discrepancy. After determining that these were unlikely explanations for the findings, we explored 2 potential sources of selection bias: one induced by self-referral of healthy participants into the study and the other induced by the design of the study itself. We concluded that both types of selection bias were likely to have occurred in this study and could account for the observed difference in rates.

Meta-analyses of colorectal cancer risk factors.

PURPOSE: Demographic, behavioral, and environmental factors have been associated with increased risk of colorectal cancer (CRC). We reviewed the published evidence and explored associations between risk factors and CRC incidence. METHODS: We identified 12 established non-screening CRC risk factors and performed a comprehensive review and meta-analyses to quantify each factor's impact on CRC risk. We used random-effects models of the logarithms of risks across studies: inverse-variance weighted averages for dichotomous factors and generalized least squares for dose-response for multi-level factors. RESULTS: Significant risk factors include inflammatory bowel disease (RR = 2.93, 95 % CI 1.79-4.81); CRC history in first-degree relative (RR = 1.80, 95 % CI 1.61-2.02); body mass index (BMI) to overall population (RR = 1.10 per 8 kg/m(2) increase, 95 % CI 1.08-1.12); physical activity (RR = 0.88, 95 % CI 0.86-0.91 for 2 standard deviations increased physical activity score); cigarette smoking (RR = 1.06, 95 % CI 1.03-1.08 for 5 pack-years); and consumption of red meat (RR = 1.13, 95 % CI 1.09-1.16 for 5 servings/week), fruit (RR = 0.85, 95 % CI 0.75-0.96 for 3 servings/day), and vegetables (RR = 0.86, 95 % CI 0.78-0.94 for 5 servings/day). CONCLUSIONS: We developed a comprehensive risk modeling strategy that incorporates multiple effects to predict an individual's risk of developing CRC. Inflammatory bowel disease and history of CRC in first-degree relatives are associated with much higher risk of CRC. Increased BMI, red meat intake, cigarette smoking, low physical activity, low vegetable consumption, and low fruit consumption were associated with moderately increased risk of CRC.

Synchronous telehealth technologies in psychotherapy for depression: a meta-analysis.

BACKGROUND: Many patients suffering from depression lack immediate access to care. The use of synchronous telehealth modalities to deliver psychotherapy is one solution to this problem. This meta-analysis examined differences in treatment efficacy for psychotherapy administered via synchronous telehealth as compared to standard nontelehealth approaches. METHOD: We located 14 articles that met inclusion criteria of the use of a synchronous telehealth modality for treatment compared to a standard nontelehealth modality comparison group. RESULTS: Overall, a statistically significant systematic difference between modes of delivery was not identified (g = 0.14, SE = 0.08, 95% CI = [-0.03, 0.30], P = .098, I(2) = 49.74%). Stratification methods and metaregression were used to analyze the contributions of type of comparison group, intervention modality, and targeted mental health outcome to moderation of effect size (ES) estimates and heterogeneity. Type of comparison group (face-to-face versus care-as-usual) had the strongest influence on observed heterogeneity and moderated the summary ES. The only detectable difference in efficacy was restricted to studies that used care-as-usual as the comparison group (g = 0.29, SE = 0.06, 95% CI = [0.16, 0.41], P < .001, I(2) = 5.14%). CONCLUSIONS: Overall, we found no evidence to suggest that the delivery of psychotherapy via synchronous telehealth modalities is less effective than nontelehealth means in reducing depression symptoms.

The effects of gay sexually explicit media on the HIV risk behavior of men who have sex with men.

This study sought to study consumption patterns of gay-oriented sexually explicit media (SEM) by men who have sex with men (MSM); and to investigate a hypothesized relationship between gay SEM consumption and HIV risk behavior. Participants were 1,391 MSM living in the US, recruited online to complete a SEM consumption and sexual risk survey. Almost all (98.5 %) reported some gay SEM exposure over the last 90 days. While 41 % reported a preference to watch actors perform anal sex without condoms (termed "bareback SEM"), 17 % preferred to actors perform anal sex with condoms (termed "safer sex SEM") and 42 % reported no preference. Overall SEM consumption was not associated with HIV risk; however participants who watched more bareback SEM reported significantly greater odds of engaging in risk behavior. The results suggest that a preference for bareback SEM is associated with engaging in risk behavior. More research to understand how MSM develop and maintain preferences in viewing SEM, and to identify new ways to use SEM in HIV prevention, is recommended.
