RESUMO
BACKGROUND: Prevention programs that are 'transdiagnostic' may be more cost-effective and beneficial, in terms of reducing levels of psychopathology in the general population, than those focused on a specific disorder. This randomized controlled study evaluated the efficacy of one such intervention program called Resilience Training (RT). METHODS: College students who reported mildly elevated depressive or subclinical psychotic symptoms ('psychotic experiences' (PEs)) (n = 107) were randomized to receiving RT (n = 54) or to a waitlist control condition (n = 53). RT consists of a four-session intervention focused on improving resilience through the acquisition of mindfulness, self-compassion, and mentalization skills. Measures of symptoms and these resilience-enhancing skills were collected before and after the 4-week RT/waitlist period, with a follow-up assessment 12-months later. RESULTS: Compared to the waitlist control group, RT participants reported significantly greater reductions in PEs, distress associated with PEs, depression, and anxiety, as well as significantly greater improvements in resilience, mindfulness, self-compassion, and positive affect, following the 4-week RT/waitlist period (all p < 0.03). Moreover, improvements in resilience-promoting skills were significantly correlated with symptom reductions (all p < 0.05). Lastly, the RT-related reductions in PEs and associated distress were maintained at the 12-month follow-up assessment. CONCLUSIONS: RT is a brief, group-based intervention associated with improved resilience and reduced symptoms of psychopathology, with sustained effects on PEs, in transdiagnostically at-risk young adults. Follow-up studies can further assess the efficacy of RT relative to other interventions and test whether it can reduce the likelihood of developing a serious mental illness.

Objectives: The aims of this study were to assess the effects of an intervention of Iyengar yoga and coherent breathing at five breaths per minute on depressive symptoms and to determine optimal intervention yoga dosing for future studies in individuals with major depressive disorder (MDD). Methods: Subjects were randomized to the high-dose group (HDG) or low-dose group (LDG) for a 12-week intervention of three or two intervention classes per week, respectively. Eligible subjects were 18-64 years old with MDD, had baseline Beck Depression Inventory-II (BDI-II) scores ≥14, and were either on no antidepressant medications or on a stable dose of antidepressants for ≥3 months. The intervention included 90-min classes plus homework. Outcome measures were BDI-II scores and intervention compliance. Results: Fifteen HDG (Mage=38.4±15.1 years) and 15 LDG (Mage=34.7±10.4 years) subjects completed the intervention. BDI-II scores at screening and compliance did not differ between groups (p=0.26). BDI-II scores declined significantly from screening (24.6±1.7) to week 12 (6.0±3.8) for the HDG (-18.6±6.6; p < 0.001), and from screening (27.7±2.1) to week 12 (10.1±7.9) in the LDG (-17.7±9.3; p < 0.001). There were no significant differences between groups, based on response (i.e., >50% decrease in BDI-II scores; p=0.65) for the HDG (13/15 subjects) and LDG (11/15 subjects) or remission (i.e., number of subjects with BDI-II scores <14; p=1.00) for the HDG (14/15 subjects) and LDG (13/15 subjects) after the 12-week intervention, although a greater number of subjects in the HDG had 12-week BDI-II scores ≤10 (p=0.04). Conclusion: During this 12-week intervention of yoga plus coherent breathing, depressive symptoms declined significantly in patients with MDD in both the HDG and LDG. Both groups showed comparable compliance and clinical improvements, with more subjects in the HDG exhibiting BDI-II scores ≤10 at week 12.
RESUMO
Introduction: The popularity of yoga has surged in recent years; however, yoga practitioners have remained a largely homogenous population. Research reflects that most practitioners are of a higher socioeconomic status. There are access barriers to yoga for lower income individuals, likely due to factors such as financial constraints and logistical challenges. The primary goal of this review was to synthesize literature on yoga research among low-income populations and better understand the feasibility and acceptability of such interventions. A secondary goal was to assess the consistency of metrics for reporting feasibility and acceptability across such studies using the CheckList Standardizing the Reporting of Interventions for Yoga (CLARIFY) guidelines as a framework. Third, the authors sought to propose additional standardized CLARIFY guidelines that may enhance reporting on the diversity of yoga research populations, adherence, and retention. Methods: The electronic databases PubMed, PsycINFO, Cochrane Central Register of Controlled Trials, and Google Scholar were searched in May 2022 using a prespecified search string. Articles assessing a yoga intervention in predominantly low-income adult populations were deemed eligible for inclusion. Results: The search resulted in 512 potential articles. Eleven were deemed eligible for inclusion. The included studies reported mostly positive effects of yoga on the target outcome (i.e., pain/disability, quality of life/wellness, and psychiatric symptoms). Recruitment and retention data showed generally good attendance and high study completion rates. Common study design components included recruitment embedded within preexisting medical settings, proximal yoga locations, and mitigation of yoga-related costs. Finally, the authors noted inconsistency in the reporting of adherence, retention, and other sociodemographic characteristics of participants and yoga instructors (e.g., race, ethnicity, and income). Discussion: Yoga may promote physical and mental health for low-income individuals. Important facilitators to access are noted, such as proximal study settings, as well as barriers such as the need for childcare that can be addressed in future research. In addition, several study design considerations could help address the specific needs of low-income participants in yoga research, such as compensating participants, recruiting within existing medical settings, and providing yoga-related equipment at no cost. Finally, the authors suggest specific ways to enhance reporting of study metrics related to socioeconomic diversity, by adding to the preexisting CLARIFY guidelines.
RESUMO
Objective: To evaluate feasibility, acceptability, and preliminary efficacy of heated yoga to treat moderate-to-severe depression.Design: An 8-week randomized controlled trial (RCT) of heated yoga versus waitlist control was conducted from March 2017 to August 2019.Methods: Participants in the yoga condition were asked to attend heated yoga classes at 2 community heated yoga studios at least twice weekly. We assessed acceptability and feasibility using exit interview and attendance data, respectively. The primary intervention efficacy outcome variable was change in the Inventory of Depressive Symptomatology-Clinician Rated (IDS-CR) score from baseline to post-intervention (week 8).Results: We randomized 80 participants and included 65 (mean [± SD] age 32.7 [± 11.7] years; 81.5% female) in the analyses (yoga n = 33, waitlist n = 32). The mean IDS-CR score at baseline was 35.6 (± 7.9) for the full sample, 36.9 (± 8.8) for yoga participants, and 34.4 (± 6.7) for waitlist participants. Participants attended an average of 10.3 (± 7.1) total classes over the 8-week intervention period. Yoga participants had a significantly greater pre- to post-intervention reduction in IDS-CR scores than waitlist participants (Cohen d = 1.04, P < .001). More yoga participants (59.3%; n = 16) than waitlist participants (6.3%; n = 2) evidenced larger treatment responses (IDS-CR ≥ 50% decrease in symptoms). Participants rated the heated yoga and its aftereffects positively in exit interviews.Conclusions: Approximately 1 heated yoga session per week (mean of 10.3 classes over 8 weeks) was associated with significantly greater reduction in depression symptoms than a waitlist control. Participants rated heated yoga positively. Taken together, results suggest feasibility, acceptability, and preliminary efficacy for patients with depression and warrant further research using active control conditions.Trial Registration: ClinicalTrials.gov identifier: NCT02607514.

BACKGROUND: Intervention research at the intersection of psychiatry and cardiology has primarily focused on the relationship between negative psychological syndromes (e.g., depression) and cardiac outcomes, with less emphasis on positive psychological attributes, such as optimism, gratitude, and well-being, as they relate to cardiac disease. METHODS: Literature is reviewed in three specific areas regarding positive attributes and cardiac disease: (1) associations between positive attributes and cardiac outcomes, (2) potential mechanisms-both behavioral and physiologic-by which positive psychological states may impact cardiovascular health, and (3) interventions aimed at cultivating positive psychological attributes in healthy and medically ill persons. RESULTS: There is significant evidence that positive psychological attributes--especially optimism--may be independently associated with superior cardiac outcomes. Positive attributes appear to be associated with increased participation in cardiac health behaviors (e.g., healthy eating, physical activity) linked to beneficial outcomes; data linking positive psychological states and biomarkers of cardiac health (e.g., inflammatory markers) is mixed but suggests a potential association. Positive psychological interventions have consistently been associated with improved well-being and reduced depressive symptoms, though there have been few such studies in the medically ill. CONCLUSIONS: These findings regarding the relationship between positive psychological attributes and cardiac health are promising and suggest that positive psychology interventions may be worth study in this population. However, questions remain about the strength and specificity of these relationships, the most salient positive psychological attributes, and the impact of positive psychological interventions on health outcomes in cardiac patients.

Depression remains difficult to treat as a result of less than optimal efficacy and troublesome side effects of antidepressants. The authors present the case of a patient with treatment-resistant depression with melancholic features who had previously been unresponsive to electroconvulsive therapy (ECT) plus an antidepressant regimen but whose condition fully remitted with the addition of a standardized form of heated hatha yoga (HY; Bikram yoga) practiced in a room heated to 105°F. The patient was a 28-year-old woman who underwent 8 weeks of HY as part of a randomized controlled trial of HY for depression while continuing her antidepressant treatment. The patient was asked to attend a minimum of 2 weekly, 90-minute HY classes. After 8 weeks (12 classes in total), the patient no longer met the criteria for a major depressive episode with melancholic features, per Mini-International Neuropsychiatric Interview (MINI) criteria. Her depressive symptoms had improved dramatically, with Inventory of Depressive Symptomatology, Clinician-Rated (IDS-C30), and Hamilton Depression Rating Scale (HAM-D28) scores decreasing from 28 at baseline to 3, and from 28 at baseline to 4, respectively, indicating remission. This patient's ECT-resistant depression remitted with the addition of HY to her antidepressant regimen. Because of her youth and athleticism, this patient was likely well suited to this rigorous form of yoga. Further research is needed to explore HY as a potential intervention for treatment-resistant depression.

BACKGROUND: Telehealth has provided many researchers, especially those conducting psychosocial research, with the tools necessary to transition from in-person to remote clinical trials during the COVID-19 pandemic. A growing body of research supports the effectiveness of telemental health for a variety of psychiatric conditions, but few studies have examined telemental health for individuals with comorbid medical diagnoses. Furthermore, little is known about the remote implementation of clinical trials examining telemental health interventions. OBJECTIVE: This paper outlines the procedural modifications used to facilitate conversion of an in-person randomized controlled trial of cognitive behavioral therapy (CBT) for depression in individuals with traumatic brain injury (TBI; CBT-TBI) to a telemental health study administered remotely. METHODS: Given the nature of remote implementation and specific challenges experienced by individuals with TBI, considerations related to treatment delivery, remote consent, data management, neuropsychological assessment, safety monitoring, and delivery of supportive material have been discussed. Feasibility, acceptability, and safety were evaluated by examining attendance and participant responses on self-report measures of treatment satisfaction and suicidal behavior. RESULTS: High rates of treatment attendance, assessment completion, study retention, and satisfaction with the intervention and modality were reported by participants who completed at least one telemental health CBT-TBI session. CONCLUSIONS: Study modifications are necessary when conducting a study remotely, and special attention should be paid to comorbidities and population-specific challenges (eg, cognitive impairment). Preliminary data support the feasibility, acceptability, and safety of remotely conducting a randomized controlled trial of CBT-TBI.

RESUMO
Objective: To determine if a 12-week yoga intervention (YI) was associated with increased gamma aminobutyric acid (GABA) levels and decreased depressive symptoms in participants with major depressive disorder (MDD). Methods: Subjects were randomized to a high-dose group (HDG) of three YIs a week and a low-dose group (LDG) of two YIs a week. Thalamic GABA levels were obtained using magnetic resonance spectroscopy at Scan-1 before randomization. After the assigned 12-week intervention, Scan-2 was obtained, immediately followed by a YI and Scan-3. Beck Depression Inventory II (BDI-II) scores were obtained before Scan-1 and Scan-3. Settings/Location: Screenings and interventions occurred at the Boston University Medical Center. Imaging occurred at McLean Hospital. Subjects: Subjects met criteria for MDD. Intervention: Ninety minutes of Iyengar yoga and coherent breathing at five breaths per minute plus homework. Outcome measures: GABA levels and the BDI-II. Results: BDI-II scores improved significantly in both groups. GABA levels from Scan-1 to Scan-3 and from Scan-2 to Scan-3 were significantly increased in the LDG (n = 15) and showed a trend in the total cohort. Post hoc, participants were divided into two groups based on having an increase in GABA levels at Scan-2. Increases in Scan-2 GABA levels were observed in participants whose mean time between their last YI and Scan-2 was 3.93 ± 2.92 standard deviation (SD) days, but not in those whose mean time between their last YI and Scan-2 was 7.83 ± 6.88 SD. Conclusions: This study tentatively supports the hypothesis that one of the mechanisms through which yoga improves mood is by increasing the activity of the GABA system. The observed increase in GABA levels following a YI that was no longer observed 8 days after a YI suggests that the associated increase in GABA after a YI is time limited such that at least one YI a week may be necessary to maintain the elevated GABA levels.

The neuroactive steroid 3α-5α-tetrahydroprogesterone (allopregnanolone), a metabolite of progesterone, is a positive allosteric modulator of GABAA receptors, and low levels have been implicated in the etiology of mood disorders. However, it is not known whether metabolism of progesterone to allopregnanolone varies across the menstrual cycle or is low after menopause. We hypothesized that the allopregnanolone/progesterone ratio would decrease from the follicular to luteal phase. We also hypothesized that postmenopausal women would have lower levels of progesterone and allopregnanolone but similar allopregnanolone/progesterone ratios as premenopausal women in the follicular phase. Serum fasting allopregnanolone and progesterone levels were measured by gas chromatography-mass spectrometry in ten premenopausal women at the follicular, mid-cycle, and luteal phases of the menstrual cycle and in twenty-four postmenopausal women. Although allopregnanolone and progesterone levels increased from the follicular to luteal phase, the allopregnanolone/progesterone ratio decreased 8-fold [0.33 ± 0.08 (follicular) vs 0.16 ± 0.09 (mid-cycle) vs 0.04 ± 0.007 (luteal), p = 0.0003]. Mean allopregnanolone and progesterone levels were lower in postmenopausal than premenopausal women at all menstrual cycle phases (p < 0.01). The mean allopregnanolone/progesterone ratio was similar in postmenopausal and premenopausal women in the follicular phase (0.39 ± 0.08 vs 0.33 ± 0.08, p = 0.94) but was significantly lower at mid-cycle and in the luteal phase than in postmenopausal women (p < 0.01). In conclusion, the serum allopregnanolone/progesterone ratio decreases 8-fold from the follicular to luteal phase and is lower at mid-cycle and the luteal phase than in postmenopausal women. Whether these data have implications for luteal phase and other mood disorders merits further study.

PURPOSE: Early adulthood represents one period of increased risk for the emergence of a serious mental illness. The college campus provides a unique opportunity to assess and monitor individuals in this at-risk age group. However, there are no validated early detection programs that are widely implemented on college campuses. In an effort to address this gap, we designed and tested an early detection and prevention program tailored to college students. A transdiagnostic approach was employed because of evidence for shared risk factors across major mental illnesses. DESIGN: Single arm, prospective study evaluating outcomes following a 4-week intervention. METHOD: Three in-person mental health screenings were conducted on the campus of one university. Undergraduate students with at least mildly elevated, self-reported levels of depressive or subclinical psychotic symptoms, who were not receiving treatment for these symptoms, were invited to participate in a 4-session workshop focused on increasing self- and other- awareness and emotion regulation using established mindfulness, self-compassion, and mentalization principles and experiential exercises. Symptoms, resilience-promoting capacities, and aspects of social functioning were assessed pre- and post- intervention. RESULTS: 416 students were screened and a total of 63 students participated in the workshop. 91% attended at least 3 of the 4 sessions. The majority of participants found the workshop interesting and useful and would recommend it to a friend. Significant pre-to-post reductions in symptoms (depression, anxiety, and subclinical psychotic symptoms, ps < 0.004) and improvements in resilience-promoting capacities (self-compassion and self-efficacy, ps < 0.006) and indices of social functioning (social motivation, activity, and a measure of comfort with the physical presence of others, ps < 0.04) were observed. Moreover, the significant increases in resilience-promoting capacities correlated with the reductions in affective symptoms (ps < 0.03). CONCLUSIONS: These findings suggest that an on-campus mental health screening and early intervention program is feasible, acceptable, and may be associated with improvements in resilience-related capacities and symptom reductions in young adults with non-impairing, subclinical symptoms of psychopathology. Follow-up work will determine whether this program can improve both shorter and longer-term mental health and functional outcomes in this at-risk population.
RESUMO
OBJECTIVES: The aims of this study were to assess the effects of an intervention of Iyengar yoga and coherent breathing at five breaths per minute on depressive symptoms and to determine optimal intervention yoga dosing for future studies in individuals with major depressive disorder (MDD). METHODS: Subjects were randomized to the high-dose group (HDG) or low-dose group (LDG) for a 12-week intervention of three or two intervention classes per week, respectively. Eligible subjects were 18-64 years old with MDD, had baseline Beck Depression Inventory-II (BDI-II) scores ≥14, and were either on no antidepressant medications or on a stable dose of antidepressants for ≥3 months. The intervention included 90-min classes plus homework. Outcome measures were BDI-II scores and intervention compliance. RESULTS: Fifteen HDG (Mage = 38.4 ± 15.1 years) and 15 LDG (Mage = 34.7 ± 10.4 years) subjects completed the intervention. BDI-II scores at screening and compliance did not differ between groups (p = 0.26). BDI-II scores declined significantly from screening (24.6 ± 1.7) to week 12 (6.0 ± 3.8) for the HDG (-18.6 ± 6.6; p < 0.001), and from screening (27.7 ± 2.1) to week 12 (10.1 ± 7.9) in the LDG (-17.7 ± 9.3; p < 0.001). There were no significant differences between groups, based on response (i.e., >50% decrease in BDI-II scores; p = 0.65) for the HDG (13/15 subjects) and LDG (11/15 subjects) or remission (i.e., number of subjects with BDI-II scores <14; p = 1.00) for the HDG (14/15 subjects) and LDG (13/15 subjects) after the 12-week intervention, although a greater number of subjects in the HDG had 12-week BDI-II scores ≤10 (p = 0.04). CONCLUSION: During this 12-week intervention of yoga plus coherent breathing, depressive symptoms declined significantly in patients with MDD in both the HDG and LDG. Both groups showed comparable compliance and clinical improvements, with more subjects in the HDG exhibiting BDI-II scores ≤10 at week 12.
