Benefits of Yoga on IL-6: Findings from a Randomized Controlled Trial of Yoga for Depression.

The present research sought to examine whether hatha yoga, implemented as an adjunctive intervention for major depression, influences markers of inflammation. A subset of 84 participants who were enrolled in a randomized controlled trial (RCT) of hatha yoga vs. health education control provided blood samples at baseline (pre-treatment) and at 3-(during treatment) and 10-week (end of treatment) follow-up visits. To be eligible for the RCT, participants met criteria for a current or recent (past two years) major depressive episode, had current elevated depression symptoms, and current antidepressant medication use. Venous blood was drawn between 2 and 6 pm and following at least one hour of fasting, and inflammatory markers (IL-6, CRP, and TNF-α) were assayed. Effects of participation in yoga relative to health education on inflammatory markers over time were examined with latent growth analyses. We observed a significant reduction in IL-6 concentrations in the yoga treatment group relative to the health education control group as demonstrated by a negative interaction between treatment group and slope of IL-6. TNF-α and CRP did not evidence significant interactions of treatment group by mean slope or intercept. In addition to the benefits of hatha yoga as an adjunctive intervention for individuals who have shown inadequate response to antidepressant medications, our findings point to possible benefits of yoga on IL-6 in depressed populations. Further research is needed to explore the effects of hatha yoga on immune function over time.

Two Interventions for Patients with Major Depression and Severe Chronic Obstructive Pulmonary Disease: Impact on Dyspnea-Related Disability.

OBJECTIVE: The Personalized Intervention for Depressed Patients with Chronic Obstructive Pulmonary Disease (PID-C) is an intervention aiming to help patients adhere to their rehabilitation and care. This study tested the hypothesis that the Problem-Solving Adherence (PSA) intervention, which integrates problem-solving into adherence enhancement procedures, reduces dyspnea-related disability more than PID-C. Exploratory analyses sought to identify patients with distinct dyspnea-related disability trajectories and to compare their clinical profiles. METHODS: In this randomized controlled trial in an acute inpatient rehabilitation and community, 101 participants diagnosed with chronic obstructive pulmonary disease (COPD) and major depression were included after screening 633 consecutive admissions for acute inpatient rehabilitation. Participants underwent 14 sessions of PID-C versus PSA over 26 weeks using the Pulmonary Functional Status and Dyspnea Questionnaire. RESULTS: The study hypothesis was not supported. Exploratory latent class growth modeling identified two distinct disability trajectories. Dyspnea-related disability improved in 39% of patients and remained unchanged in the rest. Patients whose dyspnea-related disability improved had more severe disability and less sense of control over their condition at baseline. CONCLUSION: Improvement or no worsening of disability was noted in both treatment groups. This is a favorable course for depressed patients with a severe, deteriorating medical illness. PID-C is compatible with the expertise of clinicians working in community-based rehabilitation programs, and after further testing in the community, it can be integrated in the care of depressed COPD patients.

A Systematic Review of Mechanisms of Change in Body-Oriented Yoga in Major Depressive Disorders.

INTRODUCTION: Despite empirical evidence for the efficacy of body-oriented yoga as add-on treatment for major depressive disorder (MDD), the specific mechanisms by which yoga leads to therapeutic changes remain unclear. By means of a systematic review, we evaluate how the field is progressing in its empirical investigation of mechanisms of change in yoga for MDD. METHODS: To identify relevant studies, a systematic search was conducted. RESULTS: The search produced 441 articles, of which 5 were included, that empirically examined 2 psychological mechanisms (mindfulness, rumination) and 3 biological mechanisms (vagal control, heart rate variability [HRV], brain-derived neurotrophic factor [BDNF], cortisol). 2 studies found that decreased rumination and 1 study that increased mindfulness was associated with the effect of yoga on treatment outcome. In addition, preliminary studies suggest that alterations in cortisol, BDNF, and HRV may play a role in how yoga exerts its clinical effect. DISCUSSION: The results suggest that body-oriented yoga could work through some of the theoretically predicted mechanisms. However, there is a need for more rigorous designs that can assess greater levels of causal specificity.

Exercise for Cognitive Symptoms in Depression: A Systematic Review of Interventional Studies.

OBJECTIVE: To explore the effect of exercise on cognition in depression as well as the impact of potential moderators and intervention type. METHOD: Controlled and uncontrolled interventional studies that described an exercise intervention and cognitive outcomes in participants with major depressive disorder (MDD) were included following a search of Pubmed, Ovid Medline, PsycInfo and Embase from inception to January 2017. Meta-analyses were conducted to calculate Hedges' g using a random-effects model. Meta-regression explored the relationships among age, baseline cognition, frequency and duration of exercise, and cognitive outcomes. Subgroup analyses were also conducted according to type and intensity of exercise interventions. RESULTS: Of 12 controlled studies and 3 uncontrolled studies that met inclusion criteria, 9 (642 patients) were included in the meta-analysis. No significant effect of exercise was found on global cognition (Hedges' g = 0.08, P = 0.33, I2 = 0%) or on individual cognitive domains. Meta-regression analyses failed to find significant relationships among participant age, baseline cognition, number of exercise sessions per wk, duration of exercise per wk, total duration of exercise during the intervention, or improvement in global cognition. Interventions combining physical with cognitive activity significantly improved global cognition ( P = 0.048), whereas low-intensity interventions were also positive ( P = 0.048). CONCLUSIONS: No impact of physical exercise was found on cognition in MDD overall. However, we found that interventions combining physical and cognitive activities had a positive impact, and that lower-intensity interventions, where adherence was improved, also impacted positively. There remains a lack of high-quality data in this population.

Facebook for Supporting a Lifestyle Intervention for People with Major Depressive Disorder, Bipolar Disorder, and Schizophrenia: an Exploratory Study.

To examine whether Facebook could support a community-based group lifestyle intervention for adults with serious mental illness. Participants with serious mental illness and obesity enrolled in a 6-month group lifestyle program were invited to join a secret Facebook group to support their weight loss and physical activity goals. Two peer co-facilitators moderated the Facebook group. The proportion of participants who achieved ≥5% weight loss or improved fitness was measured at follow-up. The relationship between this outcome and participants' interactions in the Facebook group was examined. Interactions were defined as active contributions including posts, comments, or likes. Content of participants' Facebook posts was also explored. Participants (n = 25) had major depression (44%), bipolar disorder (36%), and schizophrenia (20%). Nineteen (76%) participants joined the Facebook group, and contributed 208 interactions (70 posts; 81 comments; 57 likes). Participants who achieved ≥5% weight loss or improved fitness contributed more interactions in the Facebook group (mean = 19.1; SD = 20.5) compared to participants who did not (mean = 3.9; SD = 6.7), though this relationship approached statistical significance (t = -2.1; Welch's df = 13.1; p = 0.06). Participants' posts containing personal sharing of successes or challenges to adopting healthy behaviors generated more interaction compared to posts containing program reminders (p < 0.01), motivational messages (p < 0.01), and healthy eating content (p < 0.01). Facebook appears promising for supporting health behavior change among people with serious mental illness. These findings can inform social media initiatives to scale up health promotion efforts targeting this at-risk group.

Adjunctive yoga v. health education for persistent major depression: a randomized controlled trial.

BACKGROUND: The objective of this study was to determine whether hatha yoga is an efficacious adjunctive intervention for individuals with continued depressive symptoms despite antidepressant treatment. METHOD: We conducted a randomized controlled trial of weekly yoga classes (n = 63) v. health education classes (Healthy Living Workshop; HLW; n = 59) in individuals with elevated depression symptoms and antidepressant medication use. HLW served as an attention-control group. The intervention period was 10 weeks, with follow-up assessments 3 and 6 months afterwards. The primary outcome was depression symptom severity assessed by blind rater at 10 weeks. Secondary outcomes included depression symptoms over the entire intervention and follow-up periods, social and role functioning, general health perceptions, pain, and physical functioning. RESULTS: At 10 weeks, we did not find a statistically significant difference between groups in depression symptoms (b = -0.82, s.e. = 0.88, p = 0.36). However, over the entire intervention and follow-up period, when controlling for baseline, yoga participants showed lower levels of depression than HLW participants (b = -1.38, s.e. = 0.57, p = 0.02). At 6-month follow-up, 51% of yoga participants demonstrated a response (⩾50% reduction in depression symptoms) compared with 31% of HLW participants (odds ratio = 2.31; p = 0.04). Yoga participants showed significantly better social and role functioning and general health perceptions over time. CONCLUSIONS: Although we did not see a difference in depression symptoms at the end of the intervention period, yoga participants showed fewer depression symptoms over the entire follow-up period. Benefits of yoga may accumulate over time.

The Relation Between Catastrophizing and Occupational Disability in Individuals with Major Depression: Concurrent and Prospective Associations.

Background Catastrophic thinking has been associated with occupational disability in individuals with debilitating pain conditions. The relation between catastrophic thinking and occupational disability has not been previously examined in individuals with debilitating mental health conditions. The present study examined the relation between catastrophic thinking and occupational disability in individuals with major depression. Methods The study sample consisted of 80 work-disabled individuals with major depressive disorder (MDD) who were referred to an occupational rehabilitation service. Participants completed measures of depressive symptom severity, catastrophic thinking and occupational disability at admission and termination of a rehabilitation intervention. Return-to-work outcomes were assessed 1 month following the termination of the rehabilitation intervention. Results Cross-sectional analyses of admission data revealed that catastrophic thinking contributed significant variance to the prediction of self-reported occupational disability, beyond the variance accounted for by depressive symptom severity. Prospective analyses revealed that reductions in catastrophic thinking predicted successful return to work following the rehabilitation intervention, beyond the variance accounted for by reductions in depressive symptom severity. Conclusions The findings suggest that catastrophic thinking is a determinant of occupational disability in individuals with major depressive disorder. The findings further suggest that interventions designed to reduce catastrophic thinking might promote occupational re-integration in individuals with debilitating mental health conditions.

Returning to Work after a Common Mental Health Disorder: a New Preoccupation for Mental Health Professionals?

BACKGROUND: Since 2010, the Belgian mental healthcare system has been involved in a structural reform: the main objective of this reorganisation is to foster the reintegration in the community of patients suffering from a mental health disorder. In parallel, the role of mental health professionals has evolved these last years: from a strictly clinical role, to the preoccupation with the rehabilitation of social competencies such as enhancing patients' abilities to return to work. The aim of this paper is to explore, specifically for patients hospitalized for a common mental health disorder, the predictive variables of returning to work within 6 months after hospitalization (RTW6). SUBJECTS AND METHODS: Our sample was extracted from routinely collected data during the patients' hospital stay (10 days) at the Psychosomatic Rehabilitation Day Centre of CHU Godinne. A sample of 134 patients participated in our study. Those patients were contacted 6 months after their hospitalization to assess resumption of work. RESULTS: We found that a patient's sociodemographicand socioeconomic variables, and depressive symptoms at the beginning of hospitalization were not predictive of return to work within 6 months (RTW6). On the other hand, duration of absence from work before hospitalization and the diagnosis of a major depression in particular were negatively associated with RTW6, whereas improvement of depressive symptoms during hospitalization stay was positively associated to RTW6. CONCLUSION: Our study identified the diagnosis of major depression and the duration of absence from work before hospitalization as two important risk factors impeding a fast return to work for patients hospitalised for a common mental health disorder. As the preoccupation with patients' abilities to return to work is now on the agenda of mental health professionals, special support and supervision should be dedicated to the more vulnerable patients.

Executive Dysfunction Predicts Treatment Response to Neuroplasticity-Based Computerized Cognitive Remediation (nCCR-GD) in Elderly Patients with Major Depression.

OBJECTIVES: Executive dysfunction (ED) is a predictor of poor treatment response of late-life depression to pharmacotherapy. In response to the consistency of these findings, we designed neuroplasticity-based computerized cognitive remediation (nCCR-GD) intervention to target and improve ED in patients who failed to remit with antidepressant treatment. This study tests the hypothesis that ED at baseline will predict favorable treatment response to nCCR-GD. METHODS: 11 elderly patients with treatment-resistant major depression were treated with a 30-hour, 4-week, unblinded, nCCR-GD treatment trial. Neuropsychological performance was assessed at baseline and after treatment ceased. RESULTS: ED at baseline was associated with greater reduction in Montgomery-Asberg Depression Rating Scale score over the 4-week treatment ß = -0.74, F(2,8) = 10.85, p = 0.009, R(2) = 0.55. CONCLUSIONS: ED predicts favorable treatment response to nCCR-GD in older adults suffering from major depression resistant to antidepressants. This finding is opposed to studies testing pharmacotherapy where ED predicts poorer treatment response.

Associations Between Negative and Positive Life Events and the Course of Depression: A Detailed Repeated-Assessments Study.

Although the effects of life events on the onset of depression are well documented, little is known regarding their effects on the course of symptoms in depressed persons. We prospectively examined the associations between negative and positive life events and the course of depressive symptomatology in depressed primary care patients. A total of 267 depressed patients were followed for 3 years using a repeated-assessments design consisting of 36 monthly assessments of the 9 Diagnostic and Statistical Manual of Mental Disorders depression symptoms and positive and negative life events. We examined whether the severity of depressive symptomatology changed directly after the occurrence of a life event. Negative events were not associated with short-term changes in depressive symptomatology. In contrast, positive events were followed by a significant decrease in depressive symptoms one and two months after their occurrence. These findings may translate into emphasis during treatment on engagement in activities that may increase the chance of positive life experiences.

Cognitive remediation for depressed inpatients: Results of a pilot randomized controlled trial.

OBJECTIVE: Neurocognitive deficits that persist despite antidepressive treatment and affect social and vocational functioning are well documented in major depressive disorder. Cognitive training approaches have proven successful in ameliorating these deficits in other psychiatric groups, but very few studies have been conducted in unipolar depressive patients by now. In contrast to previous studies solely including outpatients, effects of a cognitive remediation intervention on neurocognitive functioning of depressed inpatients were assessed by the present study. METHOD: A randomized controlled trial was carried out with 46 depressed inpatients of a psychiatric hospital. Patients were randomly assigned to either a control group that received standard drug and non-drug (cognitive behavioural, occupational, sports, relaxation and music therapy) antidepressive treatment or a remediation group that additionally received 12 sessions of cognitive training for a total of 4 weeks (three sessions per week). An intent to treat analysis and a last observation carried forward method was used for data analyses. RESULTS: Patients of the remediation group demonstrated greater improvements in neurocognitive measures of verbal and nonverbal memory, working memory and executive function (Cohen's d effect sizes between .52 and .98). CONCLUSIONS: These results provide preliminary evidence that cognitive remediation interventions can be successfully applied also in psychiatric inpatients experiencing an acute depressive episode.

Finding Identity and Meaning as a Nurse with a Mental Illness.

Through professional acculturation, nurses establish their identities as nurses. They also develop of an understanding what mental illness and associated phenomena mean. When nurses themselves develop mental illness, they must learn to establish a new identity as a patient and more specifically as a nurse-patient, and come to a new understanding of what mental illness means to them. This autoethnographic paper focuses on the author's own experience of finding an identity as nurse-patient and discovering what that really meant, at the same time incorporating analysis to connect the personal and the cultural.

Reliability and Validity of the Meaningfulness of Songwriting Scale (MSS) with Adults on Acute Psychiatric and Detoxification Units.

BACKGROUND: Songwriting is an intervention with demonstrated clinical benefit for a range of clinical populations. Researchers argue that positive outcomes are in part the result of the meaningfulness of the creative process. However, no measure currently exists to quantify the extent of meaning derived from songwriting processes. OBJECTIVE: To psychometrically evaluate the Meaningfulness of Songwriting Scale (MSS) as a measure of meaning of a therapeutic songwriting process. METHOD: 147 participants receiving short-term mental health care (39 acute psychiatric care; 108 detoxification unit) were asked to complete the MSS and the Short State Flow Scale immediately following a songwriting music therapy session. Six hours later, participants completed the MSS a second time. Analyses were performed by participant cohort to determine the content validity, internal consistency, test-retest reliability, measurement error, and construct validity. RESULTS: Findings indicated that the MSS has good content validity, strong internal consistency (α = 0.98, acute psychiatric group, and α = 0.96, detoxification group), acceptable test-retest reliability (ICC2,1 = 0.93, acute psychiatric group, and ICC2,1 = 0.89, detoxification group), and construct validity (acute group was r = 0.68, p < 0.001, and detoxification group was r = 0.56, p < 0.001). Measurement error was greater in the detoxification group, suggesting that the measure may be unstable for this group. CONCLUSIONS: Preliminary evidence supports MSS use for research with inpatients on acute psychiatric units; however, cautious use is recommended for use with inpatients in detoxification units due to measurement error.

Citizenship and recovery: two intertwined concepts for civic-recovery.

BACKGROUND: Validation of the psychometric properties of a new measure of citizenship was required for a research project in the province of Quebec, Canada. This study was meant to study the interplay between recovery- and citizenship-oriented supportive employment. As recovery and citizenship were expected to be two related concepts, convergent validity between the Citizenship Measure (CM) and the Recovery Assessment Scale (RAS) was tested. METHODS: Study objectives were to: 1) conduct exploratory factor analyses on the CM and confirmatory factor analysis on the RAS tools (construct validity), 2) calculate Cronbach's alphas for each dimension emerging from objective 1 (reliability), and 3) calculate correlations between all dimensions from both tools (convergent validity). Data were collected from 174 individuals with serious mental illness, working in social firms. Serious mental illnesses include major depression, schizophrenia, bipolar disorder, obsessive compulsive disorder, panic disorder, post traumatic stress disorder and borderline personality disorder. RESULTS: Five factors emerged from the exploratory factor analysis of the CM, with good reliability. Confirmatory factor analyses showed that the short and the long versions of the RAS present satisfactory results. Finally, the correlation matrix indicated that all dimensions from both tools are significantly correlated, thus confirming their convergent validity. CONCLUSIONS: This study confirms the validity and reliability of two tools, CM and RAS. These tools can be used in combination to assess citizenship and recovery, both of which may be combined in the new concept of civic-recovery.

Correlates of major depressive disorder with and without comorbid alcohol use disorder nationally in the veterans health administration.

BACKGROUND AND OBJECTIVES: This study assesses medical and psychiatric comorbidities, service utilization, and psychotropic medication prescriptions in veterans with comorbid major depressive disorder (MDD) and alcohol use disorder (AUD) relative to veterans with MDD alone. METHODS: Using cross-sectional administrative data (fiscal year [FY]2012: October 1, 2011-September 30, 2012) from the Veterans Health Administration (VHA), we identified veterans with a diagnosis of current (12-month) MDD nationally (N = 309,374), 18.8% of whom were also diagnosed with current (12-month) AUD. Veterans with both MDD and AUD were compared to those with MDD alone on sociodemographic characteristics, current (12-month) medical and psychiatric disorders, service utilization, and psychotropic prescriptions. We then used logistic regression analyses to calculate odds ratio and 95% confidence interval of characteristics that were independently different between the groups. RESULTS: Dually diagnosed veterans with MDD and AUD, relative to veterans with MDD alone, had a greater number of comorbid health conditions, such as liver disease, drug use disorders, and bipolar disorder as well as greater likelihood of homelessness and higher service utilization. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Dually diagnosed veterans with MDD and AUD had more frequent medical and psychiatric comorbidities and more frequently had been homeless. These data suggest the importance of assessing the presence of comorbid medical/psychiatric disorders and potential homelessness in order to provide appropriately comprehensive treatment to dually diagnosed veterans with MDD and AUD and indicate a need to develop more effective treatments for combined disorders.

Maslow and mental health recovery: a comparative study of homeless programs for adults with serious mental illness.

This mixed-methods study uses Maslow's hierarchy as a theoretical lens to investigate the experiences of 63 newly enrolled clients of housing first and traditional programs for adults with serious mental illness who have experienced homelessness. Quantitative findings suggests that identifying self-actualization goals is associated with not having one's basic needs met rather than from the fulfillment of basic needs. Qualitative findings suggest a more complex relationship between basic needs, goal setting, and the meaning of self-actualization. Transforming mental health care into a recovery-oriented system will require further consideration of person-centered care planning as well as the impact of limited resources especially for those living in poverty.

Assessment practices of Canadian occupational therapists working with adults with mental disorders.

BACKGROUND: Little is known about assessment practices of occupational therapists working with adults with mental disorders. PURPOSE: This study investigates the assessment practices of occupational therapists working with clients experiencing symptoms of schizophrenia or major depressive disorder. METHOD: We conducted a national survey of assessment practices using case vignettes of hypothetical clients. FINDINGS: From 343 vignettes completed by 286 respondents, 68.4% included the use of one or more standardized measures during treatment. Measures were rarely repeated. Results showed that the Canadian Occupational Performance Measure was the most frequently used, suggesting a focus on assessing global functioning, while the Assessment of Motor and Process Skills was listed as the most desired assessment tool. Implementing nonstandardized assessments was common. IMPLICATIONS: Despite wide variations in occupational therapists' assessment practices, the use of standardized assessments is prevalent. The low rate of repeated measures (0% to 25.9%) suggests a need to better monitor changes and treatment outcomes.

Recalling happy memories in remitted depression: a neuroimaging investigation of the repair of sad mood.

Major depressive disorder (MDD) is a recurrent mood disorder. The high rate of recurrence of MDD suggests the presence of stable vulnerability factors that place individuals with a history of major depression at an increased risk for the onset of another episode. Previous research has linked the remitted state, and therefore increased vulnerability for depressive relapse, with difficulties in the use of pleasant autobiographical memories to repair sad mood. In the present study, we examined the neural correlates of these difficulties. Groups of 16 currently euthymic, remitted depressed individuals and 16 healthy (control) women underwent functional magnetic resonance imaging (fMRI) during sad mood induction and during recovery from a sad mood state through recall of mood-incongruent positive autobiographical memories. Sad mood was induced in participants by using film clips; participants then recalled positive autobiographical memories, a procedure previously shown to repair negative affect. During both the sad mood induction and automatic mood regulation, control participants exhibited activation in the left ventrolateral prefrontal cortex (vlPFC) and cuneus; in contrast, remitted participants exhibited a decrease in activation in these regions. Furthermore, exploratory analyses revealed that reduced activation levels during mood regulation predicted a worsening of depressive symptoms at a 20-month follow-up assessment. These findings highlight a dynamic role of the vlPFC and cuneus in the experience and modulation of emotional states and suggest that functional anomalies of these brain regions are associated with a history of, and vulnerability to, depression.

Long-term outcomes of a randomized trial of integrated skills training and preventive healthcare for older adults with serious mental illness.

OBJECTIVE: This report describes 1-, 2-, and 3-year outcomes of a combined psychosocial skills training and preventive healthcare intervention (Helping Older People Experience Success [HOPES]) for older persons with serious mental illness. METHODS: A randomized controlled trial compared HOPES with treatment as usual (TAU) for 183 older adults (age ≥ 50 years [mean age: 60.2]) with serious mental illness (28% schizophrenia, 28% schizoaffective disorder, 20% bipolar disorder, 24% major depression) from two community mental health centers in Boston, Massachusetts, and one in Nashua, New Hampshire. HOPES comprised 12 months of weekly skills training classes, twice-monthly community practice trips, and monthly nurse preventive healthcare visits, followed by a 1-year maintenance phase of monthly sessions. Blinded evaluations of functioning, symptoms, and service use were conducted at baseline and at a 1-year (end of the intensive phase), 2-year (end of the maintenance phase), and 3-year (12 months after the intervention) follow-up. RESULTS: HOPES compared with TAU was associated with improved community living skills and functioning, greater self-efficacy, lower overall psychiatric and negative symptoms, greater acquisition of preventive healthcare (more frequent eye exams, visual acuity, hearing tests, mammograms, and Pap smears), and nearly twice the rate of completed advance directives. No differences were found for medical severity, number of medical conditions, subjective health status, or acute service use at the 3-year follow-up. CONCLUSION: Skills training and nurse facilitated preventive healthcare for older adults with serious mental illness was associated with sustained long-term improvement in functioning, symptoms, self-efficacy, preventive healthcare screening, and advance care planning.

Exercise as an add-on strategy for the treatment of major depressive disorder: a systematic review.

Antidepressants are currently the treatment of choice for major depressive disorder (MDD). Nevertheless, a high percentage of patients do not respond to a first-line antidepressant drug, and combination treatments and augmentation strategies increase the risk of side effects. Moreover, a significant proportion of patients are treatment-resistant. In the last 30 years, a number of studies have sought to establish whether exercise could be regarded as an alternative to antidepressants, but so far no specific analysis has examined the efficacy of exercise as an adjunctive treatment in combination with antidepressants. We carried out a systematic review to evaluate the effectiveness of exercise as an adjunctive treatment with antidepressants on depression. A search of relevant papers was carried out in PubMed/Medline, Google Scholar, and Scopus with the following keywords: "exercise," "physical activity," "physical fitness," "depressive disorder," "depression," "depressive symptoms," "add-on," "augmentation," "adjunction," and "combined therapy." Twenty-two full-text articles were retrieved by the search. Among the 13 papers that fulfilled our inclusion criteria, we found methodological weaknesses in the majority. However, the included studies showed a strong effectiveness of exercise combined with antidepressants. Further analyses and higher quality studies are needed; nevertheless, as we have focused on a particular intervention (exercise in adjunction to antidepressants) that better reflects clinical practice, we can hypothesize that this strategy could be appropriately and safely translated into real-world practice.
