RESUMO
OBJECTIVE: The COVID-19 pandemic has resulted in considerable stress for families, placing parents at risk for heightened psychological distress, while prompting widespread changes in mental health service delivery. This study evaluated treatment engagement, acceptability, and psychiatric distress among participants in the telehealth adaptation of the Connecting and Reflecting Experience (CARE) program after the onset of COVID-19. METHODS: CARE is a transdiagnostic, bigenerational, mentalizing-focused group parenting intervention based out of an outpatient child mental health clinic in an underserved urban community. Individuals participating in CARE during the clinic's transition to telehealth services were recruited for participation in this pre-post design pilot study. Participants (N=12) completed self-report surveys before and after their first telehealth group session and at their 20-week follow-up. Quantitative and qualitative measures were used to evaluate psychiatric symptoms, treatment engagement, and preliminary acceptability of the adaptation. RESULTS: Self-reported mood and anxiety symptoms decreased significantly after 20 weeks of telehealth therapy. Participants reported high levels of therapeutic alliance and group cohesion in the telehealth format. Results also showed minimal participant-reported privacy concerns and a trend toward increased treatment engagement. CONCLUSIONS: These findings have implications regarding the acceptability of teletherapy interventions for caregivers of children during this period of heightened vulnerability and limited access to social support and health services. They also are relevant to establishing the preliminary acceptability of mentalizing-focused parenting inventions delivered via telehealth.

The novel coronavirus (COVID-19) has disproportionately impacted the health and socioeconomic outcomes for low-income populations, people of color, and immigrant children and families in the United States. As inequities in resources (i.e., food, internet, housing), health care, and education increased for marginalized families as a result of COVID-19, child-focused clinicians had to broaden their professional scope and implement new advocacy efforts. The current paper uses clinical vignettes taken from a New York State Office of Mental Health-licensed child and adolescent outpatient clinic in the Bronx, New York. The vignettes highlight the social inequities that impacted marginalized children and families during the pandemic, as well as the clinical team's response through the integration of evidence-base practice and advocacy. Implications for practice with vulnerable populations as the COVID-19 pandemic persists are discussed.
RESUMO
PURPOSE OF REVIEW: We review 2016-2019 peer-reviewed literature which summarizes the factors contributing to high expense of treating depression among adults in the USA, and interventions that have been conducted to decrease depression treatment expenditures. RECENT FINDINGS: Treatment expenditures associated with depression are high and growing, driven in part by increased health care utilization and a shift toward increased insurance coverage of medications and therapies. The majority of identified articles describe the elevated financial burden associated with treating individuals with chronic medical conditions who also have a depression diagnosis. The few available studies documenting health care system-level interventions identify that multi-target treatment for comorbid illness, collaborative care management, and integration of psychiatric treatment into primary care show promise for reducing depression treatment expenditures. Additional research is needed to identify innovative, cost-effective state, and federal payer-initiated depression treatment models, and evaluation of collaborative care and integrated care models implemented to scale across multiple health care systems.

BACKGROUND: This study examined whether a culturally focused psychiatric consultation program (CFP) for Latino Americans was equally effective in reducing depressive symptoms in English-speaking and Spanish-speaking patients. METHODS: The CFP utilizes the Engagement Interview Protocol (EIP), a semi-standardized protocol eliciting patient narratives about illness beliefs. The sample included 118 Latino American patients presenting with depressive symptoms. Patient-preferred primary language was examined as a moderator for the effect of CFP participation vs usual care on change in depressive symptoms. RESULTS: Multiple regression analysis revealed that the interaction effect of primary language and treatment arm on depressive symptoms, as measured by the Quick Inventory of Depressive Symptomatology-Self Report was not statistically significant at 6-month follow-up (B = -2.89, t = -1.35, P = .180). CONCLUSIONS: The findings suggest that the CFP was equally effective in both Spanish and English-speaking Latino Americans. The trend in the results toward greater reduction in depressive symptoms in primary Spanish-speaking Latino Americans as compared with primary English-speaking Latino Americans suggests the importance of receiving language-concordant care.

OBJECTIVE: This pilot study evaluated the effects of Tai Chi training on sleep quality (primary outcomes), and depression and social functioning levels (secondary outcomes) among patients with depression. PARTICIPANTS: Sixteen depressed Chinese patients. METHODS: Participants received 1-hr Tai Chi training sessions 2 times per week for 10 weeks. Patients' subjective sleep quality ratings, objective sleep quality measurements, and depression and social functioning levels were measured before, during, and after the intervention. RESULTS: Sleep quality and depression outcomes improved significantly. Patients reported improved Pittsburgh Sleep Quality Index (PSQI) scores (9.6 ± 3.3 to 6.6 ± 5.2, p = 0.016), and cardiopulmonary coupling (CPC) analysis of electrocardiogram (ECG) showed decreased stable sleep onset latency (75.7 ± 100.6 to 20.9 ± 18.0, p = 0.014), increased stable sleep percentages (31.5 ± 18.7 to 46.3 ± 16.9, p = 0.016), and decreased unstable sleep percentages (45.3 ± 20.1 to 30.6 ± 16.5, p = 0.003). Patients also reported decreased Hamilton Rating Scale for Depression (HAM-D-17; 20.1 ± 3.7 to 7.8 ± 5.9, p < 0.001) and Beck Depression Inventory (BDI) scores (22.3 ± 9.1 to 11.1 ± 10.6, p = 0.006). Significant correlations were found between the changes in subjective sleep assessments ΔPSQI and ΔHAM-D-17 (r = 0.6, p = 0.014), and ΔPSQI and ΔBDI (r = 0.62, p = 0.010). Correlations between changes in objective sleep measurements and changes in depression symptoms were low and not significant. CONCLUSIONS: Tai Chi training improved sleep quality and mood symptoms among depressed patients.

INTRODUCTION: There is mixed evidence in the literature on the role of inflammation in major depressive disorder. Contradictory findings are attributed to lack of rigorous characterization of study subjects, to the presence of concomitant medical illnesses, to the small sample sizes, and to the limited number of cytokines tested. METHODS: Subjects aged 18-70 years, diagnosed with major depressive disorder and presenting with chronic course of illness, as well as matched controls ( n = 236), were evaluated by trained raters and provided blood for cytokine measurements. Cytokine levels in EDTA plasma were measured with the MILLIPLEX Multi-Analyte Profiling Human Cytokine/Chemokine Assay employing Luminex technology. The Wilcoxon rank-sum test was used to compare cytokine levels between major depressive disorder subjects and healthy volunteers, before (interleukin [IL]-1ß, IL-6, and tumor necrosis factor-α) and after Bonferroni correction for multiple comparisons (IL-1α, IL-2, IL-3, IL-4, IL-5, IL-7, IL-8, IL-10, IL-12(p40), IL-12(p70), IL-13, IL-15, IFN-γ-inducible protein 10, Eotaxin, interferon-γ, monotype chemoattractant protein-1, macrophage inflammatory protein-1α, granulocyte-macrophage colony-stimulating factor and vascular endothelial growth factor). RESULTS: There were no significant differences in cytokine levels between major depressive disorder subjects and controls, both prior to and after correction for multiple analyses (significance set at p ⩽ 0.05 and p ⩽ 0.002, respectively). CONCLUSION: Our well-characterized examination of cytokine plasma levels did not support the association of major depressive disorder with systemic inflammation. The heterogeneity of major depressive disorder, as well as a potential sampling bias selecting for non-inflammatory depression, might have determined our findings discordant with the literature.

BACKGROUND: Psychosocial treatments and medications both have been shown to be effective in treating major depressive disorder. We hypothesized that cognitive-behavioral therapy (CBT) would outperform medication on measures of cognitive change. METHODS: We randomized depressed individuals to 12 weeks of CBT (n = 15) or escitalopram (n = 11). In an intent-to-treat analysis (n = 26), we conducted a repeated measures analysis of variance to examine changes in depressive symptoms (ie, 17-item Hamilton Depression Rating Scale, Beck Depression Inventory), anhedonia (ie, Snaith-Hamilton Pleasure Scale), cognitive measures (ie, Dysfunctional Attitudes Scale, Automatic Thoughts Questionnaire, Perceived Stress Scale), and quality of life (ie, Quality of Life Enjoyment and Satisfaction Questionnaire) at 4 time points: baseline, week 4, week 8, and week 12. Treatment for both groups started at baseline, and patients received either 12 weeks of individual CBT or 12 weeks of escitalopram with flexible dosing (10 to 20 mg). RESULTS: Collapsing the escitalopram and CBT groups, there were statistically significant pre-post changes on all outcome measures. However, there were no statistically significant differences between treatment groups on any of the outcome measures, including cognitive measures across time points. CONCLUSIONS: Our results suggest that both CBT and escitalopram have similar effects across a variety of domains and that, in contrast to our a priori hypothesis, CBT and escitalopram were associated with comparable changes on cognitive measures.

BACKGROUND: We examined whether fatigue was associated with greater symptomatic burden and functional impairment in college students with depressive symptoms. METHODS: Using data from the self-report Beck Depression Inventory (BDI), we stratified a group of 287 students endorsing significant symptoms of depression (BDI score ≥ 13) into 3 levels: no fatigue, mild fatigue, or moderate/severe fatigue. We then compared the 3 levels of fatigue across a battery of psychiatric and functional outcome measures. RESULTS: Approximately 87% of students endorsed at least mild fatigue. Students with moderate/severe fatigue had significantly greater depressive symptom severity compared with those with mild or no fatigue and scored higher on a suicide risk measure than those with mild fatigue. Students with severe fatigue evidenced greater frequency and intensity of anxiety than those with mild or no fatigue. Reported cognitive and functional impairment increased significantly as fatigue worsened. CONCLUSIONS: Depressed college students with symptoms of fatigue demonstrated functional impairment and symptomatic burden that worsened with increasing levels of fatigue. Assessing and treating symptoms of fatigue appears warranted within this population.

Major depressive disorder is often accompanied by elevated levels of anger, hostility, and irritability, which may contribute to worse outcomes. The present study is a secondary analysis examining the role of anger/hostility in the treatment response to low-dose aripiprazole added to antidepressant therapy in 225 patients with major depressive disorder and inadequate response to antidepressant treatment. Repeated-measures model demonstrated no drug-placebo difference in treatment response across levels of anger/hostility. However, within-group analyses showed significantly lower placebo response rates in patients with high anger/hostility and a trend for lower drug response rates in patients with high anger/hostility. Pooled response rates across phases and treatments revealed a lower response rate among patients with high anger/hostility. Depressed patients with high anger/hostility demonstrate greater illness severity and lower depressive treatment response rates than patients with low anger/hostility, suggesting that patients with high anger/hostility may have poorer outcomes in response to adjunctive treatment.

We compared treatment response (≥50 decrease in Nine-Item Patient Health Questionnaire total score) among 24 Latinos with major depressive disorder, presenting with and without specific psychosislike symptoms: A, hearing noises or house sounds, B, hearing voices calling one's name, C, seeing fleeting visions such as shadows, and D, symptoms more likely to be truly psychotic (e.g., poorly defined and short-lasting voices [other than B], fleeting paranoid ideation, or fleeting ideas of reference). 18 subjects (75%) endorsed symptoms of cluster A, 12 (50%) of cluster B, 10 (31%) of cluster C, and 12 (50%) of cluster D. Only subjects who reported symptoms from the D cluster exhibited significantly unfavorable depressive outcomes (compared to those with absence of D symptoms). The authors propose a phenomenological differentiation between benign psychosislike symptoms (clusters A-C) and the expression of the psychotic continuum (cluster D) in depressed Latinos.

Current measures for major depressive disorder focus primarily on the assessment of depressive symptoms, while often omitting other common features. However, the presence of comorbid features in the anxiety spectrum influences outcome and may effect treatment. More comprehensive measures of depression are needed that include the assessment of symptoms in the anxiety-depression spectrum. This study examines the reliability and validity of the Symptoms of Depression Questionnaire (SDQ), which assesses irritability, anger attacks, and anxiety symptoms together with the commonly considered symptoms of depression. Analysis of the factor structure of the SDQ identified 5 subscales, including one in the anxiety-depression spectrum, with adequate internal consistency and concurrent validity. The SDQ may be a valuable new tool to better characterize depression and identify and administer more targeted interventions.

In recent history, the world has witnessed a trend towards liberalization of abortion laws driven by an increasing understanding of the negative personal and public health consequences of criminalizing abortion. By contrast, several countries have recently implemented restrictive reproductive laws, joining the 112 countries where access to abortion care is banned completely or with narrow exceptions. On June 24, 2022, the US Supreme Court ruling in Dobbs v Jackson Women's Health Organization overturned its landmark decisions in Roe v Wade that established abortion until the point of viability of the fetus as a constitutional right. After Roe v Wade having been overturned, it is projected that many women in the USA will be prevented from accessing safe abortion care. Importantly, abortion bans not only impose constraints on patient autonomy, they also restrict physicians' ability to practice evidence-based medicine, which will negatively impact psychiatric care. It is therefore crucial for the practicing psychiatrist to be familiar with this new legal landscape. In this Personal View, we aim to provide a topical overview to help clinicians gain a clear understanding of legal, clinical, and ethical responsibilities, focusing on the USA. We also discuss the reality that psychiatrists might be called upon to determine medical necessity for an abortion on psychiatric grounds, which is new for most US psychiatrists. We predict that psychiatrists will be confronted with very difficult situations in which lawful and ethical conduct might be incongruent, and that abortion bans will result in greater numbers of patients needing psychiatric care from a system that is ill-prepared for additional demands.
RESUMO
BACKGROUND: Ongoing professional practice evaluation (OPPE) activities consist of a quantitative, competency-based evaluation of clinical performance. Hospitals must design assessments that measure clinical competencies, are scalable, and minimize impact on the clinician's daily routines. A psychiatry department at a large academic medical center designed and implemented an interactive Web-based psychiatric simulation focusing on violence risk assessment as a tool for a departmentwide OPPE. METHODS: Of 412 invited clinicians in a large psychiatry department, 410 completed an online simulation in April-May 2012. Participants received scheduled e-mail reminders with instructions describing how to access the simulation. Using the Computer Simulation Assessment Tool, participants viewed an introductory video and were then asked to conduct a risk assessment, acting as a clinician in the encounter by selecting actions from a series of drop-down menus. Each action was paired with a corresponding video segment of a clinical encounter with a standardized patient. Participants were scored on the basis of their actions within the simulation (Measure 1) and by their responses to the open-ended questions in which they were asked to integrate the information from the simulation in a summative manner (Measure 2). RESULTS: Of the 410 clinicians, 381 (92.9%) passed Measure 1,359 (87.6%) passed Measure 2, and 5 (1.2%) failed both measures. Seventy-five (18.3%) participants were referred for focused professional practice evaluation (FPPE) after failing either Measure 1, Measure 2, or both. CONCLUSIONS: Overall, Web-based simulation and e-mail engagement tools were a scalable and efficient way to assess a large number of clinicians in OPPE and to identify those who required FPPE.

BACKGROUND: People engage in nonsuicidal self-injury (NSSI) to reduce negative affect, but it is not clear why they engage in this harmful type of behavior instead of using healthier strategies. The primary goal of this study was to evaluate whether people choose NSSI to reduce negative affect because they perceive it to be less cognitively costly than other available strategies. METHOD: In experiment one, 43 adults completed a novel, relief-based effort discounting task designed to index preferences about exerting cognitive effort to achieve relief. In experiment two, 149 adults, 52 % with a history of NSSI, completed our effort discounting task. RESULTS: Our main results suggest that people will accept less relief from an aversive experience if doing so requires expending less effort, i.e. they demonstrate effort discounting in the context of decisions about relief. We also found and that effort discounting is stronger among those with a history of NSSI, but this association became nonsignificant when simultaneously accounting for other conditions associated with aberrant effort tradeoffs. LIMITATIONS: The use of a control group without NSSI or other potentially harmful relief-seeking behaviors limits our ability to draw specific conclusions about NSSI. The ecological validity of our task was limited by a modestly effective affect manipulation, and because participants made hypothetical choices. CONCLUSIONS: This study demonstrates that preferences about exerting cognitive effort may be a barrier to using healthier affect regulation strategies. Further, the preference not to exert cognitive effort, though present in NSSI, is likely not unique to NSSI. Instead, effort discounting may be a transdiagnostic mechanism promoting an array of harmful relief-seeking behaviors.

OBJECTIVE: Racial and ethnic disparities in exposure to COVID-19-related stressors, pandemic-related distress, and adverse mental health outcomes were assessed among health care workers in the Bronx, New York, during the first wave of the pandemic. METHODS: The authors analyzed survey data from 992 health care workers using adjusted logistic regression models to assess differential prevalence of outcomes by race/ethnicity and their interactions. RESULTS: Compared with their White colleagues, Latinx, Black, Asian, and multiracial/other health care workers reported significantly higher exposure to multiple COVID-19-related stressors: redeployment, fear of being sick, lack of autonomy at work, and inadequate access to personal protective equipment. Endorsing a greater number of COVID-19-related stressors was associated with pandemic-related distress in all groups and with adverse mental health outcomes in some groups; it was not related to hazardous alcohol use in any of the groups. These associations were not significantly different between racial and ethnic groups. Latinx health care workers had significantly higher probabilities of pandemic-related distress and posttraumatic stress than White colleagues. Despite greater exposure to COVID-19-related stressors, Black, Asian, and multiracial/other health care workers had the same, if not lower, prevalence of adverse mental health outcomes. Conversely, White health care workers had a higher adjusted prevalence of moderate to severe anxiety compared with Asian colleagues and greater hazardous alcohol use compared with all other groups. CONCLUSIONS: Health care workers from racial and ethnic minority groups reported increased exposure to COVID-19-related stressors, suggestive of structural racism in the health care workforce. These results underscore the need for increased support for health care workers and interventions aimed at mitigating disparities in vocational exposure to risk and stress.

Investigators from minoritized backgrounds are underrepresented in psychiatric research. That underrepresentation contributes to disparities in outcomes of access to mental health care. Drawing on lived experience, scholarly qualitative reports, and empirical data, the authors review how the underrepresentation of minoritized researchers arises from interlocking, self-reinforcing effects of structural biases in our research training and funding institutions. Minoritized researchers experience diminished early access to advanced training and opportunities, stereotype threats and microaggressions, isolation due to lack of peers and senior mentors, decreased access to early funding, and unique community and personal financial pressures. These represent structural racism-a system of institutional assumptions and practices that perpetuates race-based disparities, in spite of those institutions' efforts to increase diversity and in contradiction to the values that academic leaders outwardly espouse. The authors further review potential approaches to reversing these structural biases, including undergraduate-focused research experiences, financial support for faculty who lead training/mentoring programs, targeted mentoring through scholarly societies, better use of federal diversity supplement funding, support for scientific reentry, cohort building, diversity efforts targeting senior leadership, and rigorous examination of hiring, compensation, and promotion practices. Several of these approaches have empirically proven best practices and models for dissemination. If implemented alongside outcome measurement, they have the potential to reverse decades of structural bias in psychiatry and psychiatric research.

OBJECTIVE: To examine the prevalence of the C677T polymorphism of the methylene tetrahydrofolate reductase (MTHFR) gene and the A2756G polymorphism of methionine synthase (MS), and their impact on antidepressant response. METHODS: We screened 224 subjects (52% female, mean age 39 ± 11 years) with SCID-diagnosed major depressive disorder (MDD), and obtained 194 genetic samples. 49 subjects (49% female, mean age 36 ± 11 years) participated in a 12-week open clinical trial of fluoxetine 20-60 mg/day. Association between clinical response and C677T and A2756G polymorphisms, folate, B12, and homocysteine was examined. RESULTS: Prevalence of the C677T and A2756G polymorphisms was consistent with previous reports (C/C = 41%, C/T = 47%, T/T = 11%, A/A = 66%, A/G = 29%, G/G = 4%). In the fluoxetine-treated subsample (n = 49), intent-to-treat (ITT) response rates were 47% for C/C subjects and 46% for pooled C/T and T/T subjects (nonsignificant). ITT response rates were 38% for A/A subjects and 60% for A/G subjects (nonsignificant), with no subjects exhibiting the G/G homozygote. Mean baseline plasma B12 was significantly lower in A/G subjects compared to A/A, but folate and homocysteine levels were not affected by genetic status. Plasma folate was negatively associated with treatment response. CONCLUSION: The C677T and A2756G polymorphisms did not significantly affect antidepressant response. These preliminary findings require replication in larger samples.
