Generalized anxiety disorder prevalence and comorbidity with depression in coronary heart disease: a meta-analysis

Protecting the Protectors: Moral Injury, Coping Styles, and Mental Health of UK Police Officers and Staff Investigating Child Sexual Abuse Material

Police officers and staff who investigate child sexual abuse material (CSAM) may be at elevated risk for mental health problems, which may be mitigated or exacerbated by institutional and interpersonal factors. The current work examined mental health in a large sample of UK CSAM investigators (N = 661). Results suggest substantially elevated rates of depression and anxiety but not posttraumatic stress disorder (PTSD). Feeling successful and supported powerfully buffered against negative outcomes, whereas moral injury-particularly feelings of institutional betrayal-predicted worse outcomes. Although exposure to CSAM and contact with victims predicted worse outcomes, these effects were much smaller. Regarding coping styles, self-blame, rumination, catastrophizing, withdrawal, ignoring, and negative religious coping predicted worse outcomes, whereas positive refocusing, seeking distraction, and social support were effective. These results held controlling for demographics. These results suggest that UK CSAM police officers and staff experience elevated depression and anxiety, but institutional and interpersonal support can buffer outcomes.

Is exercise a viable therapy for anxiety? Systematic review of recent literature and critical analysis

OBJECTIVES

Exercise has been promoted as a treatment for a variety of psychiatric conditions. The benefits of exercise for depression are widely recognized, but the benefits of exercise for anxiety are uncertain. Although several reviews promoted exercise as a treatment for anxiety, concerns about the quality of studies prompted us to provide a critical review of the recent literature to re-assess the value of exercise for treating anxiety.

METHODS AND MATERIALS

We conducted a systematic review of all peer-reviewed randomized clinical trials (RCTs) among adults, published between January 2014 and December 2021, with an exercise intervention and anxiety as the a priori primary outcome. Two reviewers independently extracted data from studies meeting inclusion criteria, including sample characteristics, exercise intervention, control conditions, primary anxiety measure, relevant findings, and methodological quality quantified by PEDro scores.

RESULTS

7240 published studies from CINAHL, EMBASE, MEDLINE, and PsycINFO were screened in April 2022, with 1831 participants across 25 eligible RCTs, of which 13 included elevated anxiety at study entry as an eligibility criterion. Only two of these 13 studies, and five of 12 studies of non-anxious individuals, found anxiety to be reduced unequivocally with exercise. Most studies suffered from significant methodological limitations including concurrent therapies and lack of intention-to-treat analyses.

CONCLUSION

There remains considerable uncertainty about the value of exercise in reducing symptoms of anxiety, particularly among anxious individuals. The paucity of methodologically sound studies of patients with anxiety represents a significant gap in our knowledge and calls for more research in the area. Word count: 249.

Gender Differences in Psychological Outcomes Following Surf versus Hike Therapy among U.S. Service Members

BACKGROUND

Surf and hike therapies have demonstrated effectiveness as adjunct interventions for service members with major depressive disorder (MDD). This study explores gender differences in intervention outcomes following a pragmatic, randomized controlled trial of Surf and Hike Therapy for service members with MDD (N = 96; men, n = 46; women, n = 50).

METHODS

Clinician-administered and self-report measures (depression, anxiety, positive affect, negative affect, resilience, and pain) were completed at preprogram, postprogram, and 3-month follow-up; brief measures (depression/anxiety and positive affect) were completed before and after each session.

RESULTS

Multilevel modeling results showed that anxiety decreased from pre- to postprogram and significantly differed by gender (B = -2.26, p = 0.029), with women reporting greater reductions. The remaining outcomes from pre- to postprogram demonstrated significant improvements that did not differ by gender (ps = 0.218-0.733). There were no gender differences through follow-up (ps = 0.119-0.780). However, within sessions, women reported greater improvements in depression/anxiety (B = -0.93, p = 0.005) and positive affect (B = 3.73, p = 0.001). The change in positive affect scores within sessions was greater for women in Hike Therapy compared to men (p = 0.016).

CONCLUSIONS

Overall, results demonstrate that both genders benefit from adjunctive Surf and Hike Therapies, but women exhibit a better response in terms of longer-term anxiety and immediate psychological outcomes.

Psychometric properties and measurement invariance of the 7-item General Anxiety Disorder scale (GAD-7) in an Italian coronary heart disease population

BACKGROUND

Generalized Anxiety Disorder is predominant in coronary heart disease (CHD) patients. 7-item Generalized Anxiety Disorder (GAD-7) scale psychometric properties have never been tested in CHD populations. This study aims to verify the GAD-7 psychometric properties and measurement invariance in an Italian CHD sample.

METHOD

A baseline data secondary analysis from HEARTS-IN-DYADS study. Several healthcare facilities enrolled an adult inpatient sample. Anxiety and depression data were collected using GAD-7 and Patient Health Questionnaire 9 (PHQ-9). Factorial validity was assessed with confirmatory factor analysis; construct validity was tested by correlating GAD-7 scores with PHQ-9 scores and other sociodemographic characteristics; internal consistency reliability was assessed using Cronbach's alpha and the composite reliability index, while confirmatory multigroup factor analysis was employed to investigate measurement invariance across gender and age (65 vs. 65).

RESULTS

We enrolled 398 patients (mean age 64.7 years; 78.9 % male; 66.8 % married). Factor structure was confirmed as unidimensional. Construct validity was confirmed with significant associations between GAD-7 and PHQ-9 scores, female gender, having a caregiver, and being employed. Cronbach's alpha and composite reliability index were 0.89 and 0.90, respectively. Measurement invariance across gender and age was confirmed at the scalar level.

LIMITATIONS

A convenience sample in one European country, a small female sample, validity testing against a single criterion.

CONCLUSION

Study results demonstrate adequate validity and reliability of the GAD-7 in an Italian CHD sample. It showed satisfactory invariance properties; GAD-7 is suitable for measuring anxiety in CHD while making significant comparisons of scores among stratified gender and age groups.

A randomized controlled trial of surf and hike therapy for U.S. active duty service members with major depressive disorder

BACKGROUND

Major depressive disorder (MDD) is the most prevalent mental health disorder worldwide, including among U.S. service members. In addition to evidence-based treatments, activity-based approaches have been shown to effectively treat depressive symptoms, particularly when they occur in the natural environment.

METHODS

This study compared two activity-based interventions, Surf Therapy and Hike Therapy, on depression outcomes among 96 active duty service members with MDD. Participants were randomized to 6 weeks of Surf or Hike Therapy. Clinician-administered and self-report measures were completed at preprogram, postprogram, and 3-month follow-up. A brief depression/anxiety measure was completed before and after each activity session.

RESULTS

Multilevel modeling results showed that continuous depression outcomes changed significantly over time (ps < .001). Although service members in Hike Therapy reported higher average depression scores than those in Surf Therapy, the trajectory of symptom improvement did not significantly differ between groups. Regarding MDD diagnostic status, there were no significant differences between the groups at postprogram (p = .401), but Surf Therapy participants were more likely to remit from MDD than were those in Hike Therapy at the 3-month follow-up (p = .015).

LIMITATIONS

The sample consisted of service members, so results may not generalize to other populations. Most participants received concurrent psychotherapy or pharmacotherapy, and, although statistically accounted for, results should be interpreted in this context.

CONCLUSIONS

Both Surf and Hike Therapies appear to be effective adjunctive interventions for service members with MDD. Research is needed to examine the effectiveness of these therapies as standalone interventions.

The role of sense of coherence in reducing anxiety and depressive symptoms among patients at the first acute coronary event: A three-year longitudinal study

OBJECTIVE

Although several studies suggest an association between psychological distress and increased morbidity and mortality in various cardiac populations, little is known about positive psychological resources, like Sense of Coherence (SOC), that may reduce distress. This longitudinal observational study aimed to test the hypothesis that a strong SOC predicted a longitudinal decrease in anxiety and depression in a sample of patients after their first acute coronary event.

METHODS

A sample of 275 patients completed the Hospital Anxiety Depression Scale (HADS) and the SOC Scale at five time-points (at the baseline and after 6, 12, 24, and 36 months). Longitudinal trajectories of anxiety, depression, and SOC were examined through hierarchical (generalized) linear models, controlling for sociodemographic and clinical indicators.

RESULTS

38.6% of patients experienced clinically relevant anxiety symptoms soon after the cardiovascular event, whereas only 20.8% experienced clinically relevant depressive symptoms. Anxiety symptoms decreased over time, plateaued, and then slightly increased, whereas depressive symptoms tended to be stable; these variables were positively associated during all time points. The SOC did not change over time; a strong SOC at baseline predicted decreased anxiety and depression.

CONCLUSION

Findings showed a strong relationship between SOC and symptoms of anxiety and depression, and they suggested the importance of a salutogenic approach in clinical practice and the relevance of interventions aimed at increasing resilience resources like the SOC in patients with cardiovascular diseases.

Prevalence of depression and anxiety symptoms and their associations with cardiovascular risk factors in coronary patients

This study aimed to assess the prevalence of depression and anxiety in CHD patients and to explore the association between established cardiovascular risk factors and depression as well as anxiety. 2,216 patients with CHD confirmed by angiography were included in this cross-sectional study. Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder Scale (GAD-7) were used to assess depression and anxiety symptoms. The frequencies of individual depressive and anxiety symptoms grouped by age and gender were analyzed. Binary logistic regression analyses were used to identify cardiovascular risk factors associated with anxiety and depression. The overall prevalence rates of depression and anxiety in CHD patients were 8.2% and 5.4%, respectively. There were significant differences in the frequency of depression and anxiety symptoms between genders. However, age differences among individual depression and anxiety symptoms were insignificant. In multivariable analysis, female gender, smoking, and hyperlipidemia were associated with a more frequent depression occurrence, and female gender was associated with more frequent anxiety. Depression and anxiety were not associated with other cardiovascular risk factors. These findings suggest that a substantial proportion of CHD patients experienced anxiety and depression symptoms. Differences in depressive or anxiety symptoms among the distribution of individual symptoms need more attention. Depression was significantly associated with female gender, smoking, and hyperlipidemia. No anxiety symptom associations with cardiovascular risk factors were demonstrated to be significant except for the female. More research is needed to unravel the mechanisms of depression, anxiety, and cardiovascular disease.

Metacognitive Short-Term Intervention in Patients With Mental Disorders Following Cardiovascular Events

Background

Mental disorders are common among patients with severe cardiovascular diseases (CVD). Yet, there is a lack of easily accessible evidence-based treatments. Recent research indicates elevated prevalence of dysfunctional metacognitions in patients with mental disorders following cardiovascular events. As metacognitive therapy (MCT) is an established treatment to modify metacognitions, we tested if a brief metacognitive intervention via videotelephony is effective in this patient group.

Methods

A brief MCT treatment was tailored to CVD patients and designed as a face-to-face internet-based intervention. Five patients with CVDs and comorbid mental disorders underwent a psychocardiological examination and diagnostic approach. Each patient participated in eight 50 min sessions via encrypted video messenger service. Metacognitions, depression and anxiety symptoms and quality of life were assessed by self-report measures pre- and post-treatment. Patients rated dysfunctional thought processes, current psychological impairment, and treatment satisfaction after each session. Intended follow-up measures were not reported due to missing data.

Results

For most patients, the brief metacognitive intervention was associated with a decrease in dysfunctional metacognitions and a reduction of symptoms of anxiety and depression post-treatment. Psychological and physiological quality of life improved. Patients reported high satisfaction with the tailored treatment.

Conclusion

Our results suggest that a brief internet-based metacognitive treatment may be a promising tool for patients with CVDs and comorbid mental disorders. Feasibility and acceptance of the intervention was rated high by the patients. Further research is necessary to support the preliminary findings and to adapt and evaluate the intervention in a controlled clinical trial setting.

Prevalence of Moderate to Severe Anxiety Symptoms among Patients with Myocardial Infarction: a Meta-Analysis

This study attempted to synthesize the evidence on the prevalence of moderate to severe anxiety symptoms among myocardial infarction (MI) patients to offer a reliable and accurate estimate on the number of MI patients suffering from moderate to severe anxiety symptoms. Comprehensive electronic searches (PubMed, Embase and Web of Science) were performed from their inception to February 2021. Between-study heterogeneity was analyzed using the Cochran's Q test and [Formula: see text] statistic, and if it was high across the eligible studies, meta-regression and subgroup analyses were conducted to examine the source of heterogeneity. Publication bias and the robustness of the pooled results were also examined. A total of 18 eligible studies covering 8,532 MI patients were included, of which 3,443 were identified with moderate to severe anxiety symptoms. Between-study heterogeneity was high ([Formula: see text]=98.8%) with the reported prevalence ranging from 9.6% to 69.17%, and the pooled prevalence was 38.08% (95% confidence interval: 28.82-47.81%) by a random-effects model. Meta-regression analyses indicated that publication year (β = -0.014) was significant moderators contributing 16.11% to the heterogeneity. Subgroup analyses indicated that studies using the anxiety subscale of Brief Symptom Inventory to assess anxiety were homogenous ([Formula: see text]=0.0). Furthermore, the pooled prevalence of moderate to severe anxiety symptoms varied significantly by geographic region, instrument used to assess anxiety, methodological quality, sex, education level, a history of previous MI and hypercholesterolemia. Additionally, the results of Egger's linear test (t = -0.630) and Begg's rank test (z = -0.190) indicated no evidence of publication bias, and the sensitivity of the pooled results was low. Nearly two fifth of MI patients suffered from moderate to severe anxiety symptoms, which emphasizes the importance of early identification of anxiety symptoms after MI, as well as the need of implementing psychological interventions for those with elevated anxiety symptoms.

Transdiagnostic Cognitive-Behavioral Therapy for Depression and Anxiety Disorders in Cardiovascular Disease Patients: Results From the CHAMPS Pilot-Feasibility Trial

OBJECTIVE

The aim of the Cardiovascular Health in Anxiety and Mood Problems Study (CHAMPS) is to pilot the Unified Protocol (UP) for the transdiagnostic treatment of depression and anxiety disorders in patients recently hospitalized for cardiovascular diseases (CVDs) and evaluate the feasibility.

METHODS

The present study is a controlled, block randomized pragmatic pilot-feasibility trial incorporating qualitative interview data, comparing UP (n = 9) with enhanced usual care (EUC, n = 10). Eligible trial participants had a recent CVD-cause admission and were above the severity threshold for depression or anxiety denoted by Patient Health Questionnaire (PHQ-9) total scores ≥10 and/or Generalized Anxiety Disorder (GAD-7) total scores ≥7 respectively on two occasions, and met criteria for one or more depression or anxiety disorders determined by structured clinical interview. Study outcomes were analyzed as intention-to-treat using linear mixed models and qualitative interview data were analyzed with content analysis.

RESULTS

Quantitative and qualitative measured indicated acceptability of the transdiagnostic CBT intervention for CVD patients with depression or anxiety disorders. Satisfaction with UP was comparable to antidepressant therapy and higher than general physician counseling. However, there were difficulties recruiting participants with current disorders and distress on two occasions. The UP was associated with a reduction in total number of disorders determined by blinded raters. Linear mixed models indicated that a significantly greater reduction in anxiety symptoms was evident in the UP group by comparison to the EUC group (GAD-7, p between groups = 0.011; Overall Anxiety Severity and Impairment Scale, p between groups = 0.013). Results favored the UP group by comparison to EUC for change over 6 months on measures of physical quality of life and harmful alcohol use. There was no difference between the two groups on changes in depression symptoms (PHQ-9), stress, metacognitive worry beliefs, physical activity, or adherence.

DISCUSSION

In conclusion, this feasibility trial indicates acceptability of transdiagnostic CBT intervention for CVD patients with depression or anxiety disorders that is tempered by difficulties with recruitment. Larger trials are required to clarify the efficacy of transdiagnostic depression and anxiety disorder CBT in populations with CVDs and depressive or anxiety disorders.

Effect of Exercise, Escitalopram, or Placebo on Anxiety in Patients With Coronary Heart Disease: The Understanding the Benefits of Exercise and Escitalopram in Anxious Patients With Coronary Heart Disease (UNWIND) Randomized Clinical Trial

IMPORTANCE

Anxiety is common among patients with coronary heart disease (CHD) and is associated with worse health outcomes; however, effective treatment for anxiety in patients with CHD is uncertain.

OBJECTIVE

To determine whether exercise and escitalopram are better than placebo in reducing symptoms of anxiety as measured by the Hospital Anxiety and Depression-Anxiety Subscale (HADS-A) and in improving CHD risk biomarkers.

DESIGN, SETTING, AND PARTICIPANTS

This randomized clinical trial was conducted between January 2016 and May 2020 in a tertiary care teaching hospital in the US and included 128 outpatients with stable CHD and a diagnosed anxiety disorder or a HADS-A score of 8 or higher who were older than 40 years, sedentary, and not currently receiving mental health treatment.

INTERVENTIONS

Twelve weeks of aerobic exercise 3 times per week at an intensity of 70% to 85% heart rate reserve, escitalopram (up to 20 mg per day), or placebo pill equivalent.

MAIN OUTCOMES AND MEASURES

The primary outcome was HADS-A score. CHD biomarkers included heart rate variability, baroreflex sensitivity, and flow-mediated dilation, along with 24-hour urinary catecholamines.

RESULTS

The study included 128 participants. The mean (SD) age was 64.6 (9.6) years, and 37 participants (29%) were women. Participants randomized to the exercise group and escitalopram group reported greater reductions in HADS-A (exercise, -4.0; 95% CI, -4.7 to -3.2; escitalopram, -5.7; 95% CI, -6.4 to -5.0) compared with those randomized to placebo (-3.5; 95% CI, -4.5 to -2.4; P = .03); participants randomized to escitalopram reported less anxiety compared with those randomized to exercise (-1.67; 95% CI, -2.68 to -0.66; P = .002). Significant postintervention group differences in 24-hour urinary catecholamines were found (exercise z score = 0.05; 95% CI, -0.2 to 0.3; escitalopram z score = -0.24; 95% CI, -0.4 to 0; placebo z score = 0.36; 95% CI, 0 to 0.7), with greater reductions in the exercise group and escitalopram group compared with the placebo group (F1,127 = 4.93; P = .01) and greater reductions in the escitalopram group compared with the exercise group (F1,127 = 4.37; P = .04). All groups achieved comparable but small changes in CHD biomarkers, with no differences between treatment groups.

CONCLUSIONS AND RELEVANCE

Treatment of anxiety with escitalopram was safe and effective for reducing anxiety in patients with CHD. However, the beneficial effects of exercise on anxiety symptoms were less consistent. Exercise and escitalopram did not improve CHD biomarkers of risk, which should prompt further investigation of these interventions on clinical outcomes in patients with anxiety and CHD.

Interventional Radiology in the Coronavirus Disease 2019 Pandemic: Impact on Practices and Wellbeing

PURPOSE

To report the impact of the coronavirus disease 2019 (COVID-19) pandemic on interventional radiology (IR).

MATERIALS AND METHODS

A 78-question survey was distributed to practicing interventional radiologists and IR trainees. The survey consisted of demographic and practice environment queries. Anxiety symptoms were evaluated using the Generalized Anxiety Disorder-7 (GAD-7) screener, and coping strategies were assessed using the Brief-Coping Orientation to Problems Experienced (Brief-COPE) questionnaire.

RESULTS

There were 422 respondents including 333 (78.9%) attending interventional radiologists and 89 (21.1%) interventional radiologists-in-training from 15 counties. Most respondents were from academic medical centers (n = 218; 51.7%). A large majority (n = 391; 92.7%) performed a procedure on a patient with confirmed COVID-19 infection. An N95 mask was the most common (n = 366; 93.6%) safety measure employed. Cancellation or limitation of elective procedures were reported by 276 (65.4%) respondents. Many respondents (n = 177; 41.9%) had self-reported anxiety (GAD-7 score >5) with an overall mean GAD-7 score of 4.64 ± 4.63 (range: 0-21). Factors associated with reporting anxiety included female gender (p = 0.045), increased call coverage (p = 0.048), lack of adequate departmental adjustments (p <0.0001), and lack of adjustments in a timely manner (p <0.0001). The most utilized coping strategy was acceptance (mean of 5.49 ± 1.88), while the most employed dysfunctional coping strategy was self-distraction (mean of 4.16 ± 1.67). The odds of reporting anxiety increased by >125% with adoption of dysfunctional strategies.

CONCLUSION

The COVID-19 pandemic induced practice alterations and high rates of self-reported anxiety in IR. Female gender, increased call coverage, and lack of adequate or timely departmental adjustments were associated with increased anxiety levels.

Effects of Acute Exercise on Anxiety Ratings in Patients With Coronary Heart Disease and Elevated Anxiety

PURPOSE

To explore individual differences in state anxiety following a single, acute bout of aerobic exercise among anxious patients with diagnosed coronary heart disease (CHD).

METHODS

One hundred eighteen CHD patients with elevated symptoms of anxiety enrolled in the UNderstanding the Benefits of Exercise and Escitalopram in Anxious Patients WIth coroNary Heart Disease (UNWIND) clinical trial rated their level of anxiety using a 100-mm visual analog scale before and after a symptom-limited exercise treadmill test. A number of exercise (eg, peak oxygen uptake, exercise duration, maximum heart rate, anaerobic threshold) and psychological variables were examined as potential predictors of exercise response. Changes in anxiety and their association with psychological variables were examined using general linear models.

RESULTS

Fifty patients (42%) rated a reduction in anxiety relative to their pre-exercise ratings following the exercise treadmill test. While a number of factors were examined, the only factor that distinguished those individuals who reported a reduction in anxiety symptoms compared with those who either remained the same or actually reported an increase in anxiety was a higher pre-exercise visual analog scale anxiety rating. No differences were observed as a function of sex, severity of trait anxiety, the presence of an anxiety disorder, exercise test duration, or age.

CONCLUSIONS

Although many variables were examined, only higher baseline anxiety distinguished those who showed a reduction in their visual analog scale ratings from those whose anxiety remained the same or got worse. The extent to which the response to acute exercise predicts the anxiolytic effects of chronic exercise needs further study.

Examination of the best cut-off points of PHQ-2 and GAD-2 for detecting depression and anxiety in Italian cardiovascular inpatients

OBJECTIVE

Despite the frequent association between anxiety, depression and cardiovascular diseases (CVD), cardiovascular inpatients are not usually screened for these psychopathological conditions. To fill this gap, especially in hospital environments, there is the need of brief screening instruments that provide reliable information in a very short time. According to this need, the aim of this study was to examine the best cut-off points of two brief and easy-to-use questionnaires in a sample of Italian cardiovascular inpatients: the 2-item Patient Health Questionnaire (PHQ-2) and the 2-item Generalized Anxiety Disorder (GAD-2).

DESIGN

3500 cardiovascular inpatients were recruited and completed both the 9-item Patient Health Questionnaire (PHQ-9) and the 7-item Generalized Anxiety Disorder (GAD-7). PHQ-2 and GAD-2 were then obtained extracting the first two item from PHQ-9 and GAD-7.

MAIN OUTCOME MEASURES

The PHQ-2 and GAD-2 psychometric properties were calculated comparing them with PHQ-9 and GAD-7, respectively.

RESULTS

The PHQ-2 threshold of ≥ 2 and the GAD-2 threshold of ≥ 3 are the best solutions in balancing between sensitivity and specificity, also providing acceptable rates of false positives and false negatives.

CONCLUSIONS

the PHQ-2 and GAD-2 Italian versions showed good diagnostic features for measuring depression and anxiety in CVD patients.

Association of Recognized and Unrecognized Myocardial Infarction With Depressive and Anxiety Disorders in 125,988 Individuals: A Report of the Lifelines Cohort Study

OBJECTIVE

No previous study has focused on recognition of myocardial infarction (MI) and the presence of both depressive and anxiety disorders in a large population-based sample. The aim of this study was to investigate the association of recognized MI (RMI) and unrecognized MI (UMI) with depressive and anxiety disorders.

METHODS

Analyses included 125,988 individuals enrolled in the Lifelines study. Current mental disorders according to the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) were assessed with the Mini-International Neuropsychiatric Interview. UMI was detected using electrocardiogram in participants who did not report a history of MI. The classification of RMI was based on self-reported MI history together with the use of either antithrombotic medications or electrocardiogram signs of MI. Analyses were adjusted for age, sex, smoking, somatic comorbidities, and physical health-related quality of life as measured by the RAND 36-Item Health Survey in different models.

RESULTS

Participants with RMI had significantly higher odds of having any depressive and any anxiety disorder as compared with participants without MI (depressive disorder: odds ratio [OR] = 1.86, 95% confidence interval [CI] = 1.38-2.52; anxiety disorder: OR = 1.60, 95% CI = 1.32-1.94) after adjustment for age and sex. Participants with UMI did not differ from participants without MI (depressive disorder: OR = 1.60, 95% CI = 0.96-2.64; anxiety disorder: OR = 0.73, 95% CI = 0.48-1.11). After additional adjustment for somatic comorbidities and low physical health-related quality of life, the association between RMI with any depressive disorder was no longer statistically significant (OR = 1.18; 95% CI =0.84-1.65), but the association with any anxiety disorder remained (OR = 1.27, 95% CI = 1.03-1.57).

CONCLUSIONS

Recognition of MI seems to play a major role in the occurrence of anxiety, but not depressive, disorders.

Dynamic changes of amplitude of low-frequency fluctuations in patients with generalized anxiety disorder

Previous neuroimaging studies have mainly focused on alterations of static and dynamic functional connectivity in patients with generalized anxiety disorder (GAD). However, the characteristics of local brain activity over time in GAD are poorly understood. This study aimed to investigate the abnormal time‐varying local brain activity of GAD by using the amplitude of low‐frequency fluctuation (ALFF) method combined with sliding‐window approach. Group comparison results showed that compared with healthy controls (HCs), patients with GAD exhibited increased dynamic ALFF (dALFF) variability in widespread regions, including the bilateral dorsomedial prefrontal cortex, hippocampus, thalamus, striatum; and left orbital frontal gyrus, inferior parietal lobule, temporal pole, inferior temporal gyrus, and fusiform gyrus. The abnormal dALFF could be used to distinguish between patients with GAD and HCs. Increased dALFF variability values in the striatum were positively correlated with GAD symptom severity. These findings suggest that GAD patients are associated with abnormal temporal variability of local brain activity in regions implicated in executive, emotional, and social function. This study provides insight into the brain dysfunction of GAD from the perspective of dynamic local brain activity, highlighting the important role of dALFF variability in understanding neurophysiological mechanisms and potentially informing the diagnosis of GAD.

Generalized Anxiety Disorder (GAD) and Comorbid Major Depression with GAD Are Characterized by Enhanced Nitro-oxidative Stress, Increased Lipid Peroxidation, and Lowered Lipid-Associated Antioxidant Defenses

Accumulating evidence shows that nitro-oxidative pathways play an important role in the pathophysiology of major depressive disorder (MDD) and bipolar disorder (BD) and maybe anxiety disorders. The current study aims to examine superoxide dismutase (SOD1), catalase, lipid hydroperoxides (LOOH), nitric oxide metabolites (NOx), advanced oxidation protein products (AOPP), malondialdehyde (MDA), glutathione (GSH), paraoxonase 1 (PON1), high-density lipoprotein cholesterol (HDL), and uric acid (UA) in participants with and without generalized anxiety disorder (GAD) co-occurring or not with BD, MDD, or tobacco use disorder. Z unit-weighted composite scores were computed as indices of nitro-oxidative stress driving lipid and protein oxidation. SOD1, LOOH, NOx, and uric acid were significantly higher and HDL and PON1 significantly lower in participants with GAD than in those without GAD. GAD was more adequately predicted by increased SOD + LOOH + NOx and lowered HDL + PON1 composite scores. Composite scores of nitro-oxidative stress coupled with aldehyde and AOPP production were significantly increased in participants with comorbid GAD + MDD as compared with all other study groups, namely MDD, GAD + BD, BD, GAD, and healthy controls. In conclusion, GAD is characterized by increased nitro-oxidative stress and lipid peroxidation and lowered lipid-associated antioxidant defenses, while increased uric acid levels in GAD may protect against aldehyde production and protein oxidation. This study suggests that increased nitro-oxidative stress and especially increased SOD1 activity, NO production, and lipid peroxidation as well as lowered HDL-cholesterol and PON1 activity could be novel drug targets for GAD especially when comorbid with MDD.

The effect of exercise therapy on depressive and anxious symptoms in patients with ischemic heart disease: A systematic review

OBJECTIVE

Depressive and anxiety symptoms are associated with Ischemic Heart Disease (IHD). Exercise interventions might improve both depressive and anxiety symptoms, but an overview of the evidence is lacking. Therefore, we systematically reviewed the existing literature on the effectiveness of exercise therapy to reduce depression and anxiety symptoms specifically in patients with IHD.

METHODS

MEDLINE, EMBASE, PsycINFO and the Cochrane Central Register of Controlled Trials were searched until January 2016. The effectiveness of exercise was assessed within two groups: a) patients selected for study with severe depression or anxiety; and b) studies that did not exclusively targeted patients with increased levels of depression or anxiety. Secondary outcomes were mortality, cardiac events, re-hospitalizations and cardiovascular risk factors.

RESULTS

We included fourteen studies. Clinical and methodological heterogeneity precluded meta-analysis. Three studies specifically included patients with high levels of depression or anxiety and eleven studies selected patients with unclear levels of depression or anxiety. Some RCTs showed that exercise was effective in lowering severe depressive symptoms (short and long term follow-up), but for the group with unclear depressive symptoms the results were non-conclusive. In the group with elevated anxiety symptoms, exercise had a positive effect on the short term follow-up. In the group with unclear anxiety symptoms the results were inconsistent (short and long term follow-up). No differences were found regarding the secondary outcomes.

CONCLUSIONS

There is a general paucity of data on the effect of exercise, precluding firm conclusions about the effectiveness of exercise for depressive and anxiety symptoms in IHD patients.

Use of selective-serotonin reuptake inhibitors and platelet aggregation inhibitors among individuals with co-occurring atherosclerotic cardiovascular disease and depression or anxiety

OBJECTIVE

Medications commonly used to treat heart disease, anxiety, and depression can interact resulting in an increased risk of bleeding, warranting a cautious approach in medical decision making. This retrospective, descriptive study examined the prevalence and the factors associated with the use of both selective-serotonin reuptake inhibitor and platelet aggregation inhibitor among individuals with co-occurring atherosclerotic cardiovascular disease and anxiety or depression.

METHODS

Respondents aged 22 years and older, alive throughout the study period, and diagnosed with co-occurring atherosclerotic cardiovascular disease and anxiety or depression (n = 1507) in years 2007 through 2013 of the Medical Expenditures Panel Survey were included. The use of treatment was grouped as follows: selective-serotonin reuptake inhibitor and platelet aggregation inhibitor, selective-serotonin reuptake inhibitor or platelet aggregation inhibitor, and neither selective-serotonin reuptake inhibitor nor platelet aggregation inhibitor.

RESULTS

Overall, 16.5% used both selective-serotonin reuptake inhibitor and platelet aggregation inhibitor, 61.2% used selective-serotonin reuptake inhibitor or platelet aggregation inhibitor, and 22.3% used neither selective-serotonin reuptake inhibitor nor platelet aggregation inhibitor. Respondents aged over 65 years (adjusted odds ratio = 1.93 (95% confidence interval = 1.08-3.45)) and having a diagnosis of diabetes (adjusted odds ratio = 1.63 (95% confidence interval = 1.15-2.31)) and hypertension (adjusted odds ratio = 1.84 (95% confidence interval = 1.04-3.27)) were more likely to be prescribed the combination.

CONCLUSION

The drug interaction was prevalent in patients who are already at higher risk of health disparities and worse outcomes thus requiring vigilant evaluation.

Anxiety Disorders and Cardiovascular Disease

Anxiety and its associated disorders are common in patients with cardiovascular disease and may significantly influence cardiac health. Anxiety disorders are associated with the onset and progression of cardiac disease, and in many instances have been linked to adverse cardiovascular outcomes, including mortality. Both physiologic (autonomic dysfunction, inflammation, endothelial dysfunction, changes in platelet aggregation) and health behavior mechanisms may help to explain the relationships between anxiety disorders and cardiovascular disease. Given the associations between anxiety disorders and poor cardiac health, the timely and accurate identification and treatment of these conditions is of the utmost importance. Fortunately, pharmacologic and psychotherapeutic interventions for the management of anxiety disorders are generally safe and effective. Further study is needed to determine whether interventions to treat anxiety disorders ultimately impact both psychiatric and cardiovascular health.

Mediationg Role of Mindfulness as a Trait Between Attachment Styles and Depressive Symptoms

Attachment styles and dysfunctional symptoms have been associated. This relationship could be affected by metacognitive capacity. The aim of this study is to clarify the relationship between depressive symptoms, attachment styles, and metacognitive capacity. In addition, the mediating role of metacognition between attachment and depressive symptoms has been studied. A total of 505 participants recruited from the general population of the province of Bizkaia (Spain) completed questionnaires regarding depression, anxiety, mindfulness, decentering, and attachment. Results showed positive and significant relations between (a) dysfunctional symptoms and insecure attachment styles and (b) metacognitive capacity and secure attachment style. Additionally, the mediating role of metacognition between attachment and depressive symptoms was confirmed. Intervention in metacognitive abilities such as mindfulness could be a useful therapeutic tool for depressive symptoms.

Development and validation of parallel short forms PaSA-cardio for the assessment of general anxiety in cardiovascular rehabilitation patients using Rasch analysis

OBJECTIVE

To develop and validate parallel short forms for the assessment of general anxiety in cardiovascular rehabilitation patients, that facilitate repeated measurement over time without contamination from residual practice effect variance.

DESIGN

Development of the parallel short forms using Rasch analysis. Validation study.

SETTING

Cardiac rehabilitation centres in Germany.

SUBJECTS

Cardiovascular rehabilitation patients.

INTERVENTIONS

Not applicable.

MAIN MEASURES

Parallel short forms PaSA-cardio, Hospital Anxiety and Depression Scale, Short Form Health Survey SF-12 and Structured Clinical Interview for DSM-IV Axis I Disorders.

RESULTS

Each version of the parallel short forms (PaSA-cardio-I and PaSA-cardio-II) comprises ten items. The two forms fitted to the Rasch model with a non-significant item-trait interaction (PaSA-cardio-I: chi-square = 39.49, degrees of freedom = 30, probability = 0.12; PaSA-cardio-II: chi-square = 26.56, degrees of freedom = 30, probability = 0.65). Person-separation reliability was 0.75/0.76. Unidimensionality could be verified. Correlation between the two models was 0.94 and 0.95, and correlations with the underlying item bank were 0.95 and 0.93. Validity could be confirmed. The area under the curve was between 0.88 and 0.97 for PaSA-cardio-I and between 0.92 and 0.95 for PaSA-cardio-II.

CONCLUSIONS

Assessment of general anxiety in cardiovascular rehabilitation patients with the PaSA-cardio was valid, economical and accurate. The two forms of the PaSA-cardio are equivalent and allow retest without contamination from residual practice effect variance.

Why do workaholics experience depression? A study with Chinese University teachers

This study focuses on the relationships of workaholism to job burnout and depression of university teachers. The direct and indirect (via job burnout) effects of workaholism on depression were investigated in 412 Chinese university teachers. Structural equation modeling and bootstrap method were used. Results revealed that workaholism, job burnout, and depression significantly correlated with each other. Structural equation modeling and bootstrap test indicated the partial mediation role of job burnout on the relationship between workaholism and depression. The findings shed some light on how workaholism influenced depression and provided valuable evidence for prevention of depression in work.

A systematic review of reviews on the prevalence of anxiety disorders in adult populations

BACKGROUND

A fragmented research field exists on the prevalence of anxiety disorders. Here, we present the results of a systematic review of reviews on this topic. We included the highest quality studies to inform practice and policy on this issue.

METHOD

Using PRISMA methodology, extensive electronic and manual citation searches were performed to identify relevant reviews. Screening, data extraction, and quality assessment were undertaken by two reviewers. Inclusion criteria consisted of systematic reviews or meta-analyses on the prevalence of anxiety disorders that fulfilled at least half of the AMSTAR quality criteria.

RESULTS

We identified a total of 48 reviews and described the prevalence of anxiety across population subgroups and settings, as reported by these studies. Despite the high heterogeneity of prevalence estimates across primary studies, there was emerging and compelling evidence of substantial prevalence of anxiety disorders generally (3.8-25%), and particularly in women (5.2-8.7%); young adults (2.5-9.1%); people with chronic diseases (1.4-70%); and individuals from Euro/Anglo cultures (3.8-10.4%) versus individuals from Indo/Asian (2.8%), African (4.4%), Central/Eastern European (3.2%), North African/Middle Eastern (4.9%), and Ibero/Latin cultures (6.2%).

CONCLUSIONS

The prevalence of anxiety disorders is high in population subgroups across the globe. Recent research has expanded its focus to Asian countries, an increasingly greater number of physical and psychiatric conditions, and traumatic events associated with anxiety. Further research on illness trajectories and anxiety levels pre- and post-treatment is needed. Few studies have been conducted in developing and under-developed parts of the world and have little representation in the global literature.

Treatment of anxiety in patients with coronary heart disease: Rationale and design of the UNderstanding the benefits of exercise and escitalopram in anxious patients WIth coroNary heart Disease (UNWIND) randomized clinical trial

BACKGROUND

Anxiety is highly prevalent among patients with coronary heart disease (CHD), and there is growing evidence that high levels of anxiety are associated with worse prognosis. However, few studies have evaluated the efficacy of treating anxiety in CHD patients for reducing symptoms and improving clinical outcomes. Exercise and selective serotonin reuptake inhibitors have been shown to be effective in treating patients with depression, but have not been studied in cardiac patients with high anxiety.

METHODS

The UNWIND trial is a randomized clinical trial of patients with CHD who are at increased risk for adverse events because of comorbid anxiety. One hundred fifty participants with CHD and elevated anxiety symptoms and/or with a diagnosed anxiety disorder will be randomly assigned to 12 weeks of aerobic exercise (3×/wk, 35 min, 70%-85% VO2peak), escitalopram (5-20 mg qd), or placebo. Before and after 12 weeks of treatment, participants will undergo assessments of anxiety symptoms and CHD biomarkers of risk, including measures of inflammation, lipids, hemoglobin A1c, heart rate variability, and vascular endothelial function. Primary outcomes include post-intervention effects on symptoms of anxiety and CHD biomarkers. Secondary outcomes include clinical outcomes (cardiovascular hospitalizations and all-cause death) and measures of quality of life.

CONCLUSIONS

The UNWIND trial (ClinicalTrials.gov NCT02516332) will evaluate the efficacy of aerobic exercise and escitalopram for improving anxiety symptoms and reducing risk for adverse clinical events in anxious CHD patients.

The Space From Heart Disease Intervention for People With Cardiovascular Disease and Distress: A Mixed-Methods Study

Background

Poor self-management of symptoms and psychological distress leads to worse outcomes and excess health service use in cardiovascular disease (CVD). Online-delivered therapy is effective, but generic interventions lack relevance for people with specific long-term conditions, such as cardiovascular disease.

Objective

To develop a comprehensive online CVD-specific intervention to improve both self-management and well-being, and to test acceptability and feasibility.

Methods

Informed by the Medical Research Council (MRC) guidance for the development of complex interventions, we adapted an existing evidence-based generic intervention for depression and anxiety for people with CVD. Content was informed by a literature review of existing resources and trial evidence, and the findings of a focus group study. Think-aloud usability testing was conducted to identify improvements to design and content. Acceptability and feasibility were tested in a cross-sectional study.

Results

Focus group participants (n=10) agreed that no existing resource met all their needs. Improvements such as "collapse and expand" features were added based on findings that participants’ information needs varied, and specific information, such as detecting heart attacks and when to seek help, was added. Think-aloud testing (n=2) led to changes in font size and design changes around navigation. All participants of the cross-sectional study (10/10, 100%) were able to access and use the intervention. Reported satisfaction was good, although the intervention was perceived to lack relevance for people without comorbid psychological distress.

Conclusions

We have developed an evidence-based, theory-informed, user-led online intervention for improving self-management and well-being in CVD. The use of multiple evaluation tests informed improvements to content and usability. Preliminary acceptability and feasibility has been demonstrated. The Space from Heart Disease intervention is now ready to be tested for effectiveness. This work has also identified that people with CVD symptoms and comorbid distress would be the most appropriate sample for a future randomized controlled trial to evaluate its effectiveness.

Panic disorder and incident coronary heart disease: a systematic review and meta-analysis protocol

BACKGROUND

The clinical presentation of panic disorder and panic attack overlaps many symptoms typically experienced in coronary heart disease (CHD). Etiological links between panic disorder and CHD are controversial and remain largely tenuous. This systematic review aims to pool together data regarding panic disorder with respect to incident CHD or myocardial infarction.

METHODS/DESIGN

Electronic databases (MEDLINE, EMBASE, PsycINFO and SCOPUS) will be searched using a search strategy exploding the topics for CHD and panic disorder. Authors and reference lists of included studies will also be contacted to identify additional published and unpublished studies. Eligibility criteria are as follows:

POPULATION

persons without CHD who meet criteria for panic disorder, panic attack, anxiety neurosis or elevated panic disorder symptoms; Comparison: persons without CHD who do not meet criteria for panic disorder, panic attack, anxiety neurosis or elevated panic disorder symptoms;

OUTCOME

verified fatal and non-fatal CHD at follow-up; including coronary revascularization procedure, coronary artery disease, and myocardial infarction. Studies adopting self-report CHD will be ineligible. Screening will be undertaken by two independent reviewers with disagreements resolved through discussion. Data extraction will include original data specified as hazard ratios, risk ratios, and original cell data if available. Risk of bias assessment will be undertaken by two independent reviewers. Meta-analytic methods will be used to synthesize the data collected relating to the CHD outcomes with Cochrane Review Manager 5.3.

DISCUSSION

This systematic review aims to clarify whether panic disorder is associated with elevated risk for subsequent CHD. An evaluation of the etiological links between panic disorder with incident CHD might inform evidence-based clinical practice and policy concerning triaging chest pain patients, diagnostic assessment, and psychiatric intervention with panic disorder patients.

The association between mood and anxiety disorders, and coronary heart disease in Brazil: a cross-sectional analysis on the Brazilian longitudinal study of adult health (ELSA-Brasil)

Background: Associations between major depressive disorder (MDD) and coronary heart disease (CHD) have been established, and these associations increase risk of future morbidity and mortality. Prior research has been carried out in high-income countries. Here we examine associations between the mood and anxiety disorders, and CHD in a large cohort at baseline from Brazil, a country facing a variety of challenges that may affect these associations.

Methods: Participants included 15,105 civil servants aged 35 to 74 at baseline (2008–2010) from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). CHD (N = 721) included self-reported angina pectoris (n = 305), myocardial infarction (n = 259) and coronary revascularization (n = 239). Hierarchical logistic regression analyses were conducted to estimate odds ratios and confidence intervals.

Results: Major findings indicate that comorbid MDD and anxiety disorders (n = 434) are associated with a threefold increase in CHD, MDD alone (n = 170) with a twofold increase in CHD, while generalized anxiety disorder alone (n = 1,394) and mixed anxiety and depression disorder (n = 1,844) – symptoms present, but diagnostic threshold not reached – are associated with a 1.5-fold increase in CHD, after full adjustment for covariates.

Conclusion: The association with CHD is greatest in those with psychiatric comorbidity, while associations were also observed in MDD and generalized anxiety disorder without comorbidity. While findings are limited by the cross-sectional design of the study, given the known risks associated with comorbidity of the mood and anxiety disorders with CHD, findings reinforce the importance of comprehensive health assessment in Brazil.

The Association between Antidepressant Medications and Coronary Heart Disease in Brazil: A Cross-Sectional Analysis on the Brazilian Longitudinal Study of Adult Health (ELSA-Brazil)

Background: Recent studies have highlighted associations between use of antidepressant medications and coronary heart disease (CHD). Tricyclic antidepressants (TCA) are not recommended in patients with CHD as they may increase morbidity and mortality. However, this class of antidepressants is freely prescribed in public health pharmacies, while access to other classes of antidepressants is restricted in Brazil. Here, we examine the associations between antidepressant use and prevalent CHD in a large cohort from Brazil.

Methods: Participants included 14,994 civil servants aged 35–74 years from the baseline assessment of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). CHD (n = 710) included stable angina, myocardial infarction, and coronary revascularization. Univariate (unadjusted) and multivariate (adjusted) logistic regression analyses were conducted to estimate odds ratios and confidence intervals.

Results: After full adjustment for covariates, TCA use (n = 156) was associated with a twofold increase in prevalent CHD, relative to non-use (n = 14,076). Additional sensitivity analysis revealed a threefold association for myocardial infarction (OR: 2.96, 95% CI: 1.41–6.21) and coronary revascularization (OR: 2.92, 95% CI: 1.28–6.66). There were no significant associations between antidepressant use and stable angina pectoris.

Conclusion: Findings highlight a strong association between TCA use and prevalent CHD. While the cross-sectional design is an important limitation of the present study, findings have important implications for the treatment of cardiac patients in Brazil.

Personality disorders in heart failure patients requiring psychiatric management: comorbidity detections from a routine depression and anxiety screening protocol

Several international guidelines recommend routine depression screening in cardiac disease populations. No previous study has determined the prevalence and comorbidities of personality disorders in patients presenting for psychiatric treatment after these screening initiatives. In the first stage 404 heart failure (HF) patients were routinely screened and 73 underwent structured interview when either of the following criteria were met: (a) Patient Health Questionnaire ≥10; (b) Generalized Anxiety Disorder Questionnaire ≥7); (c) Response to one item panic-screener. Or (d) Suicidality. Patients with personality disorders were compared to the positive-screen patients on psychiatric comorbidities. The most common personality disorders were avoidant (8.2%), borderline (6.8%) and obsessive compulsive (4.1%), other personality disorders were prevalent in less than <3% of patients. Personality disorder patients had significantly greater risk of major depression (risk ratio (RR) 1.2; 95% confidence interval (CI) 1.2-13.3), generalized anxiety disorder (RR 3.2; 95% CI 1.0-10.0), social phobia (RR 3.8; 95% CI 1.3-11.5) and alcohol abuse/dependence (RR 3.2; 95% 1.0-9.5). The findings that HF patients with personality disorders presented with complex psychiatric comorbidity suggest that pathways facilitating the integration of psychiatric services into cardiology settings are warranted when routine depression screening is in place.

The anxious heart in whose mind? A systematic review and meta-regression of factors associated with anxiety disorder diagnosis, treatment and morbidity risk in coronary heart disease

OBJECTIVE

To (1) report the prognostic association between anxiety disorder subtypes and major adverse cardiac events (MACE), (2) report anxiety disorder prevalence in coronary heart disease (CHD), and (3) report the efficacy of anxiety disorder treatments in CHD.

METHODS

A comprehensive electronic database search was performed in November 2013 for studies reporting anxiety disorder prevalence according to structured interview in CHD samples or MACE, and randomized controlled trials (RCTs) comparing anxiety disorder treatment with placebo or usual care. From 4041 articles 42 samples were selected for extraction (8 for MACE prognosis, 39 for prevalence, no RCTs were eligible).

RESULTS

Five generalized anxiety disorder (GAD) studies reported 883 MACE events (combined n=2851). There was a non-significant association between GAD and MACE (risk ratio=1.20, 95% CI .86-1.68, P=.28) however the effect size was highly significant in outpatient samples (adjusted hazard ratio=1.94, 95% CI 1.45-2.60, P<.001). No other anxiety disorder subtype was associated with MACE. Prevalence data showed high comorbidity with depression (49.06%; 95% CI 34.28-64.01) and substantial heterogeneity between studies. Panic disorder prevalence was higher in psychiatrist/psychologist raters (9.92% vs. 4.74%) as was GAD (18.45% vs. 13.01%). Panic and GAD estimates were also heterogeneous according to DSM-III-R versus DSM-IV taxonomies.

CONCLUSIONS

The paucity of extant anxiety disorder RCTs, alongside MACE risk for GAD outpatients, should stimulate further anxiety disorder intervention in CHD populations. Research should focus on depression and anxiety, thereby unraveling disorder specific and more generic pathways.

Anhedonic depression, history of depression, and anxiety as gender-specific risk factors of myocardial infarction in healthy men and women: The HUNT study

This prospective study examines gender-specific psychological risk factors of myocardial infarction. Out of 41,248 participants free of coronary heart disease at baseline, 822 cases of myocardial infarction were identified in the Nord-Trøndelag Health Study or the mortality register. The participants completed the Hospital Anxiety and Depression Scale. Cholesterol, blood pressure, and waist–hip ratio were measured by medical staff. Smoking, diabetes, non-fatal myocardial infarction, and history of depressive episode were self-reported. Anhedonic depression (Hospital Anxiety and Depression Scale-D ≥8) was a significant predictor of myocardial infarction in women but not in men. Gender difference in risk estimate based on Hospital Anxiety and Depression Scale-D was significant (p < .01). History of depressive episode was a significant predictor of myocardial infarction in men. Symptoms of anxiety (Hospital Anxiety and Depression Scale-A ≥8) reduced the risk of having a myocardial infarction.

Direct and indirect relationship between locus of control and depression

This study examined the mediating effect of self-esteem on the relationship between locus of control and depression among Chinese university students. In all, 457 students (232 men and 225 women) completed measures of locus of control, self-esteem, and depression. Correlational analyses indicated that external locus of control was related to self-esteem and depression, and self-esteem was related to depression. Structural equation modeling analysis showed that self-esteem partially mediated the influence of locus of control on depression. The significance of the results is discussed.

A dynamic view of comorbid depression and generalized anxiety disorder symptom change in chronic heart failure: the discrete effects of cognitive behavioral therapy, exercise, and psychotropic medication

PURPOSE

No previous study has reported upon comorbid depression and anxiety disorders and their treatment in heart failure (HF), which the current study has sought to document.

MATERIALS AND METHODS

Total 29 HF patients under psychiatric management underwent primary depression cognitive behavioral therapy (CBT; n = 15) or primary generalized anxiety disorder (GAD) CBT (n = 14), and participated in a community exercise program and standard physician care. Repeated measures analysis of variance assessed Patient Health Questionnaire (PHQ-9) and GAD-7 symptom change pre- and post-CBT treatment, and assessed the interaction effects of treatment type, exercise, anti-depressant and anxiolytic.

RESULTS

There was a significant time and treatment interaction effect that favored the primary GAD CBT group for reduction in PHQ symptoms (F(1, 24) = 4.52, p = 0.04). Analysis of PHQ-somatic symptoms also showed a significant main effect for participation in the exercise program (F(1, 24) = 4.21, p = 0.05) and a significant time and anxiolytic interaction (F(1, 24) = 3.98, p = 0.05). The average number of cardiac hospital readmissions favored the primary GAD CBT group (p = 0.05).

CONCLUSION

The findings support the use of multifaceted interventions in the rehabilitation of HF patients with comorbid psychiatric needs. Implications for Rehabilitation Comorbid depression and anxiety disorders are a clinical and research focus that deserves more attention in the treatment of heart failure patients. Cognitive behavioral therapy, exercise, and anxiolytic use was associated with significant changes in depression and anxiety though discrete effects were evident. Multifaceted interventions are most likely to be successful in the rehabilitation of HF patients with psychiatric needs.

Comorbid anxiety disorders alter the association between cardiovascular diseases and depression: the German National Health Interview and Examination Survey

PURPOSE

This study aims to examine whether specific anxiety disorder comorbidity alters the purported association between depression and specific cardiovascular diseases (CVDs).

METHODS

In 4,181 representative German participants of the general population, 12-month prevalence of psychiatric disorders was assessed through the Composite International Diagnostic Interview and CVDs by physician verified diagnosis. Adjusting for conventional risk factors logistic regression analyzed the association between CVDs (peripheral vascular disease (PVD), hypertension, cerebrovascular disease and heart disease) and combinations of comorbidity between depression and anxiety disorder types (panic disorder, specific phobia, social phobia and generalized anxiety).

RESULTS

There were 770 cases of hypertension (18.4 %), 763 cases of cerebrovascular disease (18.2 %), 748 cases of PVD (17.9 %), and 1,087 cases of CVD (26.0 %). In adjusted analyses phobia comorbid with depression was associated with cerebrovascular disease (odds ratio (OR) 1.61; 95 % confidence interval (CI) 1.04-2.50) as was panic disorder (OR 2.89; 95 % CI 1.47-5.69). PVD was significantly associated with panic disorder (adjusted OR 2.97; 95 % CI 1.55-5.69). Panic disorder was associated with CVDs (adjusted OR 2.28; 95 % CI 1.09-4.77) as was phobia (adjusted OR 1.35; 95 % CI 1.04-1.78).

CONCLUSIONS

Classification of anxiety and depression according to comorbidity groups showed discrete effects for panic disorder and specific phobia with CVDs, independent from covariates and depression.

The real world mental health needs of heart failure patients are not reflected by the depression randomized controlled trial evidence

INTRODUCTION

International depression screening guidelines in heart failure (HF) are partly based on depression treatment efficacy from randomized controlled trials (RCTs). Our aim was to test the external validity of depression RCT criteria in a sample of real-world HF patients.

METHODS

HF patients admitted to 3 hospitals in South Australia were referred to a HF psychologist if not already receiving current psychiatric management by psychologist or psychiatrist elsewhere. Screening and referral protocol consisted of the following; (a). Patient Health Questionnaire ≥ 10; (b). Generalized Anxiety Disorder Questionnaire ≥ 7); (c). positive response to 1 item panic attack screener; (d). evidence of suicidality. Patients were evaluated against the most common RCT exclusion criteria personality disorder, high suicide risk, cognitive impairment, psychosis, alcohol or substance abuse or dependency, bi-polar depression.

RESULTS

Total 81 HF patients were referred from 404 HF admissions, and 73 were assessed (age 60.6 ± 13.4, 47.9% female). Nearly half (47%) met at least 1 RCT exclusion criterion, most commonly personality disorder (28.5%), alcohol/substance abuse (17.8%) and high suicide risk (11.0%). RCT ineligibility criteria was more frequent among patients with major depression (76.5% vs. 46.2%, p<.01) and dysthymia (26.5% vs. 7.7%, p = .03) but not significantly associated with anxiety disorders. RCT ineligible patients reported greater severity of depression (M = 16.6 ± 5.0 vs. M = 12.9 ± 7.2, p = .02) and were higher consumers of HF psychotherapy services (M = 11.5 ± 4.7 vs. M = 8.5 ± 4.8, p = .01).

CONCLUSION

In this real-world sample comparable in size to recent RCT intervention arms, patients with depression disorders presented with complex psychiatric needs including comorbid personality disorders, alcohol/substance use and suicide risk. These findings suggest external validity of depression screening and RCTs could serve as a basis for level A guideline recommendations in cardiovascular diseases.

Design and baseline data from the Management of Sadness and Anxiety in Cardiology (MOSAIC) randomized controlled trial

BACKGROUND

Depression and anxiety in cardiac patients are independently associated with adverse cardiovascular outcomes, including mortality. Collaborative care (CC) programs, which use care managers to assess patients, coordinate care, and perform therapeutic interventions, have proven effective in managing depression in this population. However, no prior CC intervention has simultaneously managed depression and anxiety disorders, and there has been minimal study of CC in high-risk cardiac inpatients.

MATERIALS AND METHODS

The Management of Sadness and Anxiety in Cardiology (MOSAIC) study was a prospective randomized trial of a low-intensity CC intervention, compared to enhanced usual care, for patients hospitalized for acute coronary syndrome, heart failure, or arrhythmia, and diagnosed with depression, generalized anxiety disorder (GAD), or panic disorder (PD). The primary outcome measure for MOSAIC was mental health-related quality of life (HRQoL), measured using the Medical Outcomes Study Short Form-12. Additional outcomes included psychological, functional, and medical outcomes, including rehospitalizations.

RESULTS

A total of 183 eligible participants were enrolled (92 collaborative care, 91 enhanced usual care); 94% of depressed patients reported being depressed for >1month, and 53% of those with GAD reported clinically significant anxiety for >1year. One hundred thirty-three patients had depression, 118 had GAD, and 19 had PD; 74 participants (40%) had two or more of the disorders.

CONCLUSION

The MOSAIC trial will provide data regarding whether an intervention that concurrently manages these common psychiatric disorders results in meaningful improvements in HRQoL, psychiatric symptoms, and medical outcomes in cardiac patients at high risk for adverse outcomes.
