The psychometric properties of the Brief Symptom Inventory depression and anxiety subscales in patients with heart failure and with or without renal dysfunction

Perceived Control, Functional Status, Depressive Symptoms, and Anxiety: Mediating and Moderating Influences on Health-Related Quality of Life in Patients With Heart Failure

BACKGROUND

Health-related quality of life (HRQoL) is poor in patients with heart failure. Psychological (ie, depressive symptoms [DS], anxiety, and perceived control) and physical (ie, functional status) factors are associated with HRQoL. The dynamic relationships among these variables and their impact on HRQoL remain unclear, limiting the ability to design effective interventions.

PURPOSE

Our aim was to evaluate a moderated mediation model, in which the association between perceived control and HRQoL was hypothesized to be mediated by DS and anxiety in the presence of a moderator, functional status.

METHODS

Patients (N = 426) with heart failure completed the Control Attitudes Scale-Revised to measure perceived control, Duke Activity Status Index for functional status, Patient Health Questionnaire-9 for DS, Brief Symptom Inventory for anxiety, and Minnesota Living with Heart Failure Questionnaire for HRQoL. We performed a moderated parallel mediation analysis.

RESULTS

Higher levels of perceived control were associated with better HRQoL through lower levels of anxiety and DS in the presence of functional status (index of moderated mediation for DS, b = 0.029; 95% confidence interval, 0.016-0.045; for anxiety: b = 0.009, 95% confidence interval, 0.002-0.018). The effect of perceived control on psychological symptoms was stronger at low and moderate functional statuses; however, this effect diminished with increasing functional status.

CONCLUSION

Functional status moderated the indirect effects of perceived control on HRQoL through DS and anxiety in patients with heart failure. Efforts to improve HRQoL by targeting perceived control may be more effective when considering DS and anxiety in patients with low to moderate levels of functional status.

The association between psychological factors and self-care in patients with heart failure: an integrative review

AIMS

This integrative review aims to describe the current evidence concerning the relationship between a broad range of psychological factors (depression, depressive symptoms, anxiety, stress, and type-D personality) and self-care in patients with heart failure.

METHODS AND RESULTS

Six electronic databases were searched and keywords were used to identify potential eligible studies published within the last 10 years. To be eligible, individuals with heart failure aged 18 years or older and who were included in any type of observational study that examined the association between psychological factors and self-care were considered. Twenty articles were included, and 16 of them reported that depression/depressive symptoms were associated with poorer self-care, after controlling for age, sex, education level, cardiac history, or comorbidities. Five studies found that self-care confidence/self-efficacy mediates the relationship between depression/depressive symptoms and self-care. The association between depression/depressive symptoms and self-care varied in assessment methods and statistical approaches. Seven studies showed an inverse association between anxiety and self-care. Four studies found a stronger association between self-care and depression compared with the relationship between self-care and other psychological factors. Stress and type-D personality were both associated with self-care in four studies.

CONCLUSION

Depression/depressive symptoms and anxiety were found to be inversely associated with self-care in patients with heart failure. Depression exhibited a stronger impact on self-care than other psychological factors. Limited studies assessed stress and type-D personality; the results should be considered with caution. Further studies are warranted on different psychological factors and their underlying mechanisms in individuals with heart failure.

The mediating role of quality of life on depression and medication adherence among patients with type 2 diabetes mellitus: A cross-sectional study

Background and Aim

Patients living with diabetes mellitus have a high burden of psychological distress such as depression and anxiety as well as impaired quality of life, which may negatively impact their adherence to medications, glucose control, and health-related costs.This study assessed the impact of quality of life and depression on medication adherence among patients with type 2 diabetes (type 2 diabetes mellitus [T2DM]) in a tertiary care setting in Ghana.

Methods

The study was a cross-sectional study involving 238 patients with diabetes aged 18 years and above. Validated tools were used to assess medication adherence, depressive symptoms, and quality of life. Structural Equation Modeling was adopted to examine the mediation effect of quality of life on the relationship between depression and medication adherence among participants.

Results

The mean age of the participants was 58.82 ± 13.49, and 169 (71.0%) out of a total of 238 respondents were females. Depression had a significant direct relationship with the quality of life of respondents [aβ (95% confidence interval, CI) = -0.20 (-0.03, -0.00), p < 0.05; -0.21 (-0.41, -0.01) p < 0.05, respectively] and indirect relationship with quality of life [aβ (95% CI) = -0.01 (-0.02, -0.004) p < 0.001]. Educational status and religion both showed a significant indirect relationship with quality of life [aβ (95% CI) = 0.06 (0.07, 0.12), p < 0.05; 0.18 (0.01, 0.35) p < 0.05, respectively]. The mediating effect of quality of life on the relationship between depression and medication adherence was significant (Sobel = -3.19, p < 0.001).

Conclusion

Depression, medication adherence, and quality of life were higher among older adults with T2DM. Depression was also found to have a strong negative association with both medication adherence and quality of life. Interventions to screen for depression and to improve the quality of life in patients living with diabetes are also recommended and this should go beyond the provision of standard treatments to explore further the mechanisms of this relationships.

Traumatic Life Events and Stressors: Associations With Substance Use Problems of Men Under Community Supervision

This study aims to determine associations between sources of stress and substance use problems among men under community supervision programs. We used ordinary least squares regression models to test the hypotheses that the traumatic life events and stressors of men under community supervision and their partners, respectively, were associated with the substance use problems of men under community supervision. The sample included 230 men involved in community supervision programs in New York City and 230 women who were their intimate partners. We found that the traumatic events and the depression and anxiety of men under community supervision and partner's substance use problems were associated with the substance use problems of the men. These findings underscore the importance of addressing trauma in substance use treatment for men under community supervision. Future research can explore how stressful events impact substance use, sources of coping for couples, and the association between racism, traumatic events, stress, and substance use. Clinical Trial Registration: NCT01690494.

Cardiac Related Psychosocial Distress and Traumatic Distress in Individuals with Advanced Heart Failure

Guided by the Transactional Model of Stress and Coping, this study explored relationships between cardiac related psychosocial distress, traumatic distress, and the number of lifetime traumas in people with advanced heart failure. Utilizing a cross-sectional survey design, a convenience sample of participants with advanced heart failure who received treatment in Washington, DC, completed standardized measures. Bivariate analysis showed a statistically significant difference in mean number of exposures and distress associated with advanced heart failure therapies and linear relationships between exposures and traumatic distress, distress and traumatic distress, and exposures and distress, as well as between the number of exposures and distress and traumatic distress and between the distress and traumatic distress. Multivariate analysis suggested that the higher the number of reported traumatic events, the higher the distress, and the higher the distress, the higher the traumatic distress. Social workers and allied team members should consider how a patient's distress relates to traumatic distress in the advanced stage heart failure population.

Comparison of two self-report scales to assess anxiety and depressive symptoms in hemodialysis patients

INTRODUCTION

Psychiatric illness is prevalent among hemodialysis (HD) patients. This study compared the assessment of anxiety and depressive symptoms among HD patients using two self-administered scales; hospital anxiety and depression scale (HADS) and brief symptom inventory (BSI).

METHODS

A cross-sectional study was conducted among a convenience sample of HD patients (n = 352) from different dialysis centers in Jordan. Patients were interviewed in dialysis units, and demographics, clinical status, disease, and dialysis history data were collected. Symptoms of anxiety (HADS-A ≥ 8 and BSI-A ≥ 0.82) and depression (HADS-D ≥ 8 and BSI-D ≥ 0.82) were also measured.

RESULTS

The mean age of participants was 52.2 ± 15.6 years. The majority had been receiving HD three times daily and for >2 years. A significant moderate-strong correlation was observed between HADS-A and BSI-A (r = 0.753, p < 0.0001) as well as HADS-D and BSI-D (r = 0.588, p < 0.0001). Anxiety prevalence was 43.7 % using HADS-A ≥ 8 and 80.7 % using BSI-A ≥ 0.82, while depression prevalence was 53.1 % using HADS-D ≥ 8 and 51.7 % using BSI-D ≥ 0.82. When HADS was used as a standard, the operating characteristics reveal that a higher cut-off for BSI-A is recommended (≥1.58) for better anxiety screening.

DISCUSSION

Specific and suitable cut-off points need to be further explored and validated for HADS and BSI scales among patients undergoing dialysis.

The Relation Between the Paraphilias and Anxiety in Men: A Case-Control Study

Despite a multitude of theoretical views, it is still unclear how individuals develop and sustain paraphilic interests (e.g., sexual attraction to children, interest in non-consensual violence). It is also not clear from these views why many paraphilic interests, and especially many paraphilias and paraphilic disorders, are much more common in men than in women. One possible factor affecting male's higher rate of paraphilias is anxiety, because anxiety can potentiate sexual arousal in men. We speculated that paraphilic interests could develop when feelings of anxiety are recurrently generated by atypical sexual stimuli, and when that anxiety repeatedly potentiates sexual arousal, reinforcing sexual response to atypical stimuli. It follows that men with paraphilic interests are susceptible to anxiety disorders, because an anxiety disorder would facilitate the hypothesized developmental process. We conducted a retrospective file review of 1048 consecutive patients (944 male patients retained for analysis) referred to an outpatient sexual behavior clinic at a psychiatric hospital to investigate the link between paraphilias and anxiety. Male patients with a paraphilia had 1.64 greater odds than male patients without a paraphilia of having been diagnosed with an anxiety disorder, but they also had elevated rates of many other types of disorders. Therefore, there does not seem to be a specific link between paraphilias and anxiety in this sample. The discovery of a general link between the paraphilias and psychological disorders in men opens new avenues for studying the developmental origins and consequences of male paraphilic interests.

Association of psychological distress with reasons for delay in seeking medical care in rural patients with worsening heart failure symptoms

BACKGROUND

The impact of depressive symptoms and anxiety on rural patients' decisions to seek care for worsening heart failure (HF) symptoms remains unknown. The purposes of this study were (1) to describe rural patients' reasons for delay in seeking care for HF, and (2) to determine whether depressive symptoms or anxiety was associated with patients' reasons for delay in seeking medical care for worsening symptoms.

METHODS

A total of 611 rural HF patients were included. Data on reasons for patient delay in seeking medical care (The Reasons for Delay Questionnaire), depressive symptoms (PHQ-9), and anxiety (BSI-ANX) were collected. Statistical analyses included chi-square and multiple regression.

RESULTS

A total of 85.4% of patients reported at least 1 reason for delay. Patients with higher levels of depressive symptoms were more likely to cite embarrassment, problems with transportation, and financial concerns as a reason for delay. Patients with anxiety not only cited nonsymptom-related reasons but also reported symptom-related reasons for delay in seeking care (ie, symptoms seemed vague, not sure of symptoms, symptoms didn't seem to be serious enough, and symptoms were different from the last episode). In multiple regression, patients with greater depressive symptoms and anxiety had a greater number of reasons for delay in seeking care (P = .003 and P = .023, respectively).

CONCLUSIONS

Our findings suggest that enhancement of patients' symptom appraisal abilities and improvement in psychological distress may result in a reduction in delay in seeking medical care for worsening symptoms in rural patients with HF.

Patterns and predictors of dyspnoea following left ventricular assist device implantation

AIMS

Dyspnoea is a common symptom of heart failure (HF) that often prompts patients to seek treatment. Implantation of a left ventricular assist device (LVAD) has been associated with reduced dyspnoea but it is unclear if all patients experience similar improvements in dyspnoea over time following LVAD implantation. Our aim was to identify distinct trajectories of dyspnoea symptoms over time following LVAD implantation and predictors of dyspnoea trajectory. We hypothesized that at least two, distinct trajectories of dyspnoea would be observed following LVAD implantation.

METHODS AND RESULTS

This was a secondary analysis of data from the Profiling Biobehavioral Responses to Mechanical Support in Advanced Heart Failure study. In the parent study, sociodemographic and clinical data were collected prior to LVAD implantation and at 1, 3, and 6 months following LVAD implantation from a sample (n = 101) of patients with advanced HF. Latent growth mixture modelling was performed to identify distinct trajectories of dyspnoea symptoms. Backwards stepwise logistic regression was used to identify predictors of dyspnoea trajectory. Two, distinct trajectories of dyspnoea symptoms were identified: sustained improvement and unsustained improvement. Participants who experienced sustained improvement (86.7% of sample) demonstrated large, significant improvement in dyspnoea from pre-implantation to 3 months post-implant followed by smaller, non-significant improvement from 3 to 6 months. Participants who experienced unsustained improvement (13.3% of sample) demonstrated initial improvement from pre-implantation to 3 months post-implantation followed by worsening of dyspnoea from 3 to 6 months. Greater depressive symptoms at baseline and living alone were significant predictors of unsustained improvement.

CONCLUSION

Patients experience different patterns of dyspnoea over time following LVAD implantation. Clinicians should inquire about living arrangements and depressive symptoms at each visit to determine risk of unsustained improvement in dyspnoea.

Profile of informal rural Appalachian caregivers of patients with chronic illnesses

PURPOSE

Caring for a family member with chronic illness increases cardiovascular disease (CVD) risk by 82%, and rurality imparts additional CVD disparities. The purpose of this study was to describe a profile of rural caregivers of patients with chronic illnesses to determine the prevalence of CVD risk factors, and psychosocial and socioeconomic burden, as well as to compare these variables across gender.

METHODS

Baseline data from a trial of CVD risk reduction in rural caregivers of patients with chronic illnesses were used. We measured depression and anxiety with the PHQ-9 and Brief Symptom Inventory; social, economic, and environmental factors using the MOS-Social Support and Economic and Environmental surveys; body mass index (BMI); blood pressure (BP); and lipid profile.

RESULTS

Of 181 caregivers (age 53±14 years, 80% female), 69% were married; 88% were caring for a family member, including 46% caring for a spouse and 18% for a parent. A total of 51% were anxious, 25% depressed, and 25% reported lack of social support. Most (51%) caregivers had one or more types of CVD; and 49% were smokers. By examination, 76% had elevated BP; 35% had total cholesterol >200; 50% low-density lipoprotein >100; 56% triglycerides >150; and 79% high-density lipoprotein <60. Based on BMI, 91.5% were overweight or obese. Gender comparisons revealed that women reported higher levels of depressive symptoms than men.

CONCLUSIONS

Rural caregivers, regardless of gender, are at increased risk of CVD and struggle with factors that make caregiving burdensome and contribute to their own poor cardiac health.

Changes in social support of pregnant and postnatal mothers during the COVID-19 pandemic

OBJECTIVE

Our objectives were to assess in perinatal women: the most effective methods used to meet social support needs during COVID-19, the impact of COVID-19 on self-reported social support levels, and how perceived change in social support related to distress, depression, and mental health.

DESIGN

One-time survey administered from April to August 2020 SETTING: Online PARTICIPANTS: Pregnant and postpartum women with infants less than 6 months of age MEASUREMENT AND FINDINGS: Participants indicated the methods they used to meet social support needs during COVID-19. They self-rated their social support level pre- and during pandemic and their distress, depressive symptoms, and mental health changes on a Likert scale. Out of 1142 participants, the most effective methods for obtaining social support during the pandemic were virtual means (e.g. video call) and interaction with friends. There was a significant difference in distribution of self-reported levels of social support before and during the pandemic, with more respondents reporting a decrease in support. Decreases in social support were associated with higher distress levels, higher levels of depressive symptoms, and poorer mental health.

KEY CONCLUSIONS

Perinatal women reported decreased social support during the COVID-19 pandemic which was associated with poorer mental health. Using virtual means of social support and support provided by friends had the largest positive effect on perceived social support levels.

IMPLICATIONS FOR PRACTICE

Interventions using virtual support means from friends may be helpful to improve social support and mental health in this population.

Delay in seeking medical care for worsening heart failure symptoms: predictors and association with cardiac events

AIMS

The association of delay in seeking medical care to subsequent cardiac events remains unknown in patients with worsening heart failure (HF) symptoms. The aims of this study were to (i) identify factors predicting care-seeking delay and (ii) examine the impact of care-seeking delay on subsequent cardiac rehospitalization or death.

METHODS AND RESULTS

We studied 153 patients hospitalized with an exacerbation of HF. Potential predictors of delay including demographic, clinical, psychosocial, cognitive, and behavioural variables were collected. Patients were followed for 3 months after discharge to determine time to the first cardiac rehospitalization or death. The median delay time was 134 h (25th and 75th percentiles 49 and 364 h). Non-linear regression showed that New York Heart Association functional class III/IV (P = 0.001), worse depressive symptoms (P = 0.004), better HF knowledge (P = 0.003), and lower perceived somatic awareness (P = 0.033) were predictors of delay time from patient perception of worsening HF to subsequent hospital admission. Cox regression revealed that patients who delayed longer (more than 134 h) had a 1.93-fold higher risk of experiencing cardiac events (P = 0.044) compared to non-delayers.

CONCLUSIONS

Care-seeking delay in patients with worsening HF symptoms was significantly associated with an increased risk of rehospitalization and mortality after discharge. Intervention strategies addressing functional status, psychological state, cognitive and behavioural factors are essential to reduce delay and thereby improve outcomes.

Screening for depression and anxiety among patients with acute coronary syndrome in acute care settings: a scoping review

OBJECTIVE

The aim of this review was to scope the literature for publications on the practice of screening for depression and anxiety in acute coronary syndrome patients in acute care by identifying instruments for the screening of anxiety and/or depression; determining if screening for anxiety and/or depression has been integrated into cardiac models of care and clinical pathways; and identifying any evidence practice gap in the screening and management of anxiety and/or depression in this population.

INTRODUCTION

Depression in acute coronary syndrome is bidirectional. Depression is an independent risk factor for cardiovascular disease, and comorbid depression is associated with a twofold greater risk of mortality in patients with cardiovascular disease. The presence of acute coronary syndrome increases the risk of depressive disorders or anxiety during the first one to two years following an acute event, and both depression and anxiety are associated with a higher risk of further acute coronary health concerns. Clinical practice guidelines have previously recommended routine screening for depression following a cardiac event, although many current guidelines do not include recommendations for screening in an acute setting. To date there have been no previous scoping reviews investigating depression and anxiety screening in patients with acute coronary syndrome in the acute care setting.

INCLUSION CRITERIA

Adults (18 years and over) with acute coronary syndrome who are screened for anxiety and/or depression (not anxiety alone) in an acute care setting.

METHODS

A systematic search of the literature was conducted by a research librarian. Research studies of any design published in English from January 1, 2012, to May 31, 2018, were included. Data were extracted from the included studies to address the three objectives. Purposefully designed tables were used to collate information and present findings. Data are also presented as figures and by narrative synthesis.

RESULTS

Fifty-one articles met the inclusion criteria. Primary research studies were from 21 countries and included 21,790 participants; clinical practice guidelines were from two countries. The most common instruments used for the screening of depression and anxiety were: i) the Hospital Anxiety and Depression Scale (n = 18); ii) the Beck Depression Inventory (n = 16); and iii) the nine-item Patient Health Questionnaire (n = 7). Eleven studies included screening for anxiety in 2181 participants (30% female) using the full version of the Hospital Anxiety and Depression Scale. The State-Trait Anxiety Inventory was used to screen 444 participants in three of the studies. Four studies applied an intervention for those found to have depression, including two randomized controlled trials with interventions targeting depression. Of the seven acute coronary syndrome international guidelines published since 2012, three (43%) did not contain any recommendations for screening for depression and anxiety, although four (57%) had recommendations for treatment of comorbidities.

CONCLUSIONS

This review has identified a lack of consistency in how depression and anxiety screening tools are integrated into cardiac models of care and clinical pathways. Guidelines for acute coronary syndrome are not consistent in their recommendations for screening for depression and/or anxiety, or in identifying the best screening tools.

Prospective Evaluation of Association Between Negative Emotions and Heart Failure Symptom Severity

Background

Prior studies of symptoms in heart failure (HF) were largely cross-sectional and symptoms were measured using retrospective recall. Because negative emotions influence information processing, retrospective symptom reports by patients with depressive symptoms and anxiety may be biased. The purpose of this study was to determine whether there are differences in patterns of symptom changes, measured prospectively, over 15 days by levels of depressive symptoms and anxiety.

Methods

HF patients (N=52) rated daily symptom severity for shortness of breath (SOB), fatigue, sleep disturbance, and edema over 15 days on a 10-point visual analogue scale. Patients were grouped into higher vs lower levels of depressive symptoms and anxiety, respectively, based on median scores of Brief Symptom Inventory subscales. Latent growth curve modeling was used to examine whether patterns of symptom changes over 15 days differed in higher vs lower levels of depressive symptom and anxiety groups.

Results

Those in the higher depressive symptom group had lower levels of baseline symptom severity in SOB (β: -1.46), fatigue (β: -1.71), sleep disturbance (β: -1.78), and edema (β: -1.97) than those in the lower depressive symptom group. However, there were no significant differences in rates of changes in the severity of any of the four symptoms between groups. Anxiety was not associated with baseline severity of symptoms or rates of changes in any of the four symptoms.

Conclusion

Depressive symptoms, but not anxiety, were associated with daily symptom experience. HF patients with higher levels of depressive symptoms may perceive their symptom severity differently than patients with lower levels of depressive symptoms.

Identifying unique profiles of perceived dyspnea burden in heart failure

BACKGROUND

Dyspnea is a common symptom of heart failure (HF) but dyspnea burden is highly variable.

OBJECTIVES

Identify distinct profiles of dyspnea burden and identify predictors of dyspnea symptom profile.

METHODS

A secondary analysis of data from five studies completed at Oregon Health and Science University was conducted. The Heart Failure Somatic Perception Scale was used to measure dyspnea burden. Latent class mixture modeling identified distinct profiles of dyspnea burden in a sample of HF patients (n = 449). Backwards stepwise multinomial logistic regression identified predictors of latent profile membership.

RESULTS

Four profiles of dyspnea burden were identified: no dyspnea/not bothered by dyspnea, mild dyspnea, moderate exertional dyspnea, and moderate exertional dyspnea with orthopnea and PND. Higher age was associated with greater likelihood of not being bothered by dyspnea than having moderate exertional dyspnea with orthopnea and PND. Higher NYHA class, anxiety, and depression were associated with greater likelihood of greater dyspnea burden.

CONCLUSIONS

Burden of dyspnea is highly variable among HF patients. Clinicians should account for the nuances of dyspnea and the activities that induce dyspnea when assessing HF patients.

Depression symptoms' impact on personality disorder treatment: Depression symptoms amplifying the interpersonal benefits of negative-affect expression

BACKGROUND

While there is some evidence that patients with elevated depression symptoms experience greater benefits from negative-affect expression, this amplifying effect has not been investigated within a psychotherapeutic context. This is particularly notable considering the substantial evidence linking affect expression with desired outcomes across psychotherapeutic approaches. The primary purpose of the present study was to investigate if depression symptoms amplified (i.e., moderated) the association between negative-affect expression and reductions in interpersonal problems for patients in a psychiatric day treatment for personality disorders. The secondary purpose was to investigate milieu (i.e., other patients concurrently enrolled) negative-affect intensity and its association with patients' reductions in interpersonal problems.

METHODS

Participants (N = 239) were patients consecutively admitted into a psychiatric day treatment program for people with personality disorders. Patients completed measures of (1) depression symptoms at pre-treatment, (2) interpersonal problems at pre- and post-treatment, and (3) negative-affect expression each week of treatment.

RESULTS

The association between patient negative-affect expression and reductions in interpersonal problems was amplified by depression symptoms. Depression symptoms also amplified the association between milieu negative-affect intensity and reductions in interpersonal problems.

CONCLUSIONS

Our findings indicate that depression symptoms amplified the therapeutic value of negative-affect expression and amplified the value of an affectively intense milieu. Practical and theoretical implications are discussed.

Evaluating emotional distress and health-related quality of life in patients with heart failure and their family caregivers: Testing dyadic dynamics using the Actor-Partner Interdependence Model

PURPOSE

1) To compare levels of emotional symptoms and health-related quality of life between patients with heart failure and their family caregivers; and 2) to examine whether patients' and caregivers' emotional symptoms were associated with their own, as well as their partner's health-related quality of life.

METHOD

In this cross-sectional study, 41 patients-caregiver dyads (78% male patients, aged 68.6 years; and 83% female caregivers, aged 65.8 years) completed all nine dimensions of the Brief Symptom Inventory and the Minnesota Living with Heart failure Questionnaire. Dyadic data were analysed for 6 sub-scales of the Brief Symptom Inventory, using the Actor-Partner Interdependence Model.

RESULTS

There were no statistically significant differences in emotional symptoms and health-related quality of life between patients with heart failure and their caregivers. Patients' and caregivers' emotional symptoms were associated with their own health-related quality of life. Caregivers' anxiety, phobic anxiety, obsession-compulsion, depression and hostility negatively influenced their partner's (i.e. the patient's) health-related quality of life. There were no partner effects of patients' emotional symptoms on the health-related quality of life of caregivers.

CONCLUSIONS

The results of this study suggest that patients may be particularly vulnerable to the emotional distress, i.e. thoughts, impulses and actions of their caregivers. It may be possible to improve patients' health-related quality of life by targeting specific detrimental emotional symptoms of caregivers.

Predictors of Adherence to Self-Care in Rural Patients With Heart Failure

BACKGROUND

The common reality of not following a recommended course of treatment is a major cause of poor health outcomes in patients with heart failure (HF). The purpose of this study was to identify predictors of adherence to HF self-care recommendations in rural HF patients who received an intervention to promote symptom management and self-care.

METHODS

Data from 349 rural HF patients (42% female, 90% Caucasian) randomized to the intervention arms of the study were used. Adherence was measured using the European Heart Failure Self-Care Scale questionnaire, a brief measure that asks patients to report their adherence to a variety of recommended HF symptom management behaviors (ie, daily weight monitoring, when to call the physician, medications, diet, and exercise). The following predictors were tested: age, gender, marital status, education level, depression score (measured using PHQ-9), anxiety score (measured with the Brief Symptom Inventory), and level of perceived control (measured using Control Attitudes Scale-R). Multivariate linear regression was used to test the model.

RESULTS

The model to predict adherence was significant (P < .0001). Of the covariates tested in the regression model, being a male (P = .009), having less anxiety (P = .018), not being depressed (P = .017), and having higher perceived control (P = .003) were predictors of improved self-care score at 3 months.

CONCLUSION

Adherence is a multifaceted and a challenging behavior based on the assumption that the patient agrees with self-care recommendations. These data suggest interventions designed to promote adherence behaviors should include an assessment of gender, anxiety, depression, and perceived control for optimal outcomes.

Cross-classification of physical and affective symptom clusters and 180-day event-free survival in moderate to advanced heart failure

BACKGROUND

The relationship between physical and affective symptom clusters in heart failure (HF) is unclear.

OBJECTIVES

To identify associations between physical and affective symptom clusters in HF and to quantify outcomes and determinants of symptom subgroups.

METHODS

This was a secondary analysis of data from two cohort studies among adults with HF. Physical and affective symptom clusters were compared using cross-classification modeling. Cox proportional hazards modeling and multinomial logistic regression were used to identify outcomes and determinants of symptom subgroups, respectively.

RESULTS

In this young, mostly male sample (n = 274), physical and affective symptom clusters were cross-classified in a model with acceptable fit. Three symptom subgroups were identified: congruent-mild (69.3%), incongruent (13.9%), and congruent-severe (16.8%). Compared to the congruent-mild symptom group, the incongruent symptom group had significantly worse 180-day event-free survival.

CONCLUSION

Congruence between physical and affective symptom clusters should be considered when identifying patients at higher risk for poor outcomes.

Investigating the Contribution of NPSR1, IL-6 and BDNF Polymorphisms to Depressive and Anxiety Symptoms in Hemodialysis Patients

AIMS

Psychological symptoms are prevalent in hemodialysis (HD) patients. Previous investigations showed that brain-derived neurotrophic factor (BDNF) and interleukin-6 (IL-6) as well as the interaction with neuropeptide S receptor 1 (NPSR1) are linked to the development of psychological distress. This study examined the association of polymorphisms of genes encoding these proteins with depression and anxiety in a representative group of Jordanian HD patients.

METHODS

A total of 302 HD patients were involved in the study and categorized into three groups based on the Hospital Anxiety and Depression Scale, HADS-D or HADS-A scores as follows: normal (<7), mild (8-10) and moderate-severe (11-21). Single nucleotide polymorphism (SNP) of NPSR1 Asn107Ile (rs324981), IL-6 G174C (rs1800795), and BDNF Val66Met (rs6265) was genotyped using blood samples.

RESULTS

The frequency of Ile-allele of NPSR1 Asn107Ile was significantly higher in patients with moderate-severe HADS-A scores versus normal (53% vs. 40.8%, p = .035). Using ordinal regression analysis, Asn-allele of NPSR1 polymorphism was nominally significantly associated with a lower risk of anxiety (OR = 0.57, CI: 0.33-0.97, p = .038) after adjusting for other covariates. A marginally significant difference in genotype distribution of IL-6 G174C was observed among patients according to HADS-D scores (p = .05). Furthermore, carriers of IL-6174 CC genotype showed lower median IL-6 serum concentration versus carriers of GG genotype (5.2 vs. 1.35 pg/mL, p < .05).

CONCLUSIONS

The results support the genetic role of NPSR1 in the pathogenesis of anxiety and suggest that carriers of NPSR1 Ile-allele are at increased risk of anxiety in HD patients. Neither BDNF Val66Met nor IL-6 G174C were linked to psychological symptoms. Future studies among other ethnicities are necessary to verify the observations.

Comparison of psychiatric screening Instruments: GHQ-28, BSI and MMPI

Background:

Clinical interview comprises a method for of psychiatric disorders diagnosis. Given the cost, time, and expertise required for clinical assessment; alternative tools to accurately substitute clinical interviews are having high value. We conduct this study to compare the screening accuracy of GHQ-28, BSI, and MMPI.

Materials and Methods:

Considering a diagnostic value, this study was conducted on 983 students and 3 psychiatric screening tools; GHQ-28, BSI, and MMPI were completed by students. Among the whole participants, 237 students were interviewed by the clinical psychiatrists on the basis of DSM-IV-IR Criteria. Based on ANOVO and Chi-square, results compare was made. Kappa correlation -coefficient was calculated in a pairwise manner; eventually the diagnostic accuracy of each tool was determined by the means of ROC analysis.

Results:

The diversity of psychiatric disorders by GHQ-28, was about 39.1, on the basis of BST was 44.8% and 44% for MMPI. The sensitivity and specificity of GHQ-28 was 85.9% and 87.8% considering 21.5 as the cut-off point; respectively. Considering 41/5 as the cut-off point for the BSI test, sensitivity and specificity were 81.2% and 90.8%; respectively, and 88.2% and 91.4% for the MMPI test with the cut-off point of 63.5 compared to clinical interview, the MMPI test was associated with the greatest accurate staging, ranging about 90.3%.

Conclusions:

The results of this study according to clinical assessment reveal that GHQ-28, BSI, and MMPI psychiatric tools have high sensitivity and specificity and MMPI possessed the greatest efficiency compared to other evaluated tools.

Social Support Moderates the Association Between Traumatic Life Events and Depression Among Migrant and Nonmigrant Men in Almaty, Kazakhstan

Across cultures, experiencing traumatic life events, particularly violence, is a salient predictor of depression. Some previous findings have shown that social support can serve as a buffer in the association between traumatic life events and depression (i.e., the buffering hypothesis) in that individuals with a high level of social support have a decreased or nonexistent association between traumatic life events and depression. The purpose of this study was to test the buffering hypothesis among a sample of 1,342 male migrant and nonmigrant market vendors in Almaty, Kazakhstan. Using multiple-group structural equation modeling (SEM), we identified the following results: (a) higher levels of traumatic life events were associated with higher depression scores, (b) higher social support scores were associated with decreased depression scores, and (c) social support buffered the association between traumatic life events and depression among migrants and nonmigrants. The final model accounted for 45.0% and 38.4% of the variance in depression for migrants and nonmigrants, respectively. Findings suggest that social support may be an important protective factor for men in Kazakhstan who have experienced trauma and call for an incorporation of social support interventions for migrant and nonmigrant men experiencing depression.

Identifying a Relationship Between Physical Frailty and Heart Failure Symptoms

BACKGROUND

Heart failure (HF) is a complex clinical syndrome associated with significant symptom burden; however, our understanding of the relationship between symptoms and physical frailty in HF is limited.

OBJECTIVE

The aim of this study was to quantify associations between symptoms and physical frailty in adults with HF.

METHODS

A sample of adults with symptomatic HF were enrolled in a cross-sectional study. Physical symptoms were measured with the HF Somatic Perception Scale-Dyspnea subscale, the Epworth Sleepiness Scale, and the Brief Pain Inventory short form. Affective symptoms were measured with the Patient Health Questionnaire-9 and the Brief Symptom Inventory-Anxiety scale. Physical frailty was assessed according to the Frailty Phenotype Criteria: shrinking, weakness, slowness, physical exhaustion, and low physical activity. Comparative statistics and generalized linear modeling were used to quantify associations between symptoms and physical frailty, controlling for Seattle HF Model projected 1-year survival.

RESULTS

The mean age of the sample (n = 49) was 57.4 ± 9.7 years, 67% were male, 92% had New York Heart Association class III/IV HF, and 67% had nonischemic HF. Physically frail participants had more than twice the level of dyspnea (P < .001), 75% worse wake disturbances (P < .001), and 76% worse depressive symptoms (P = .003) compared with those who were not physically frail. There were no differences in pain or anxiety.

CONCLUSIONS

Physically frail adults with HF have considerably worse dyspnea, wake disturbances, and depression. Targeting physical frailty may help identify and improve physical and affective symptoms in HF.

Patterns of heart failure symptoms are associated with self-care behaviors over 6 months

BACKGROUND

Both heart failure symptoms and self-care are associated with patient outcomes. Although it is thought that symptoms drive self-care, there is limited evidence to support this assumption over time.

AIMS

To determine whether patterns of physical symptoms are significantly associated with heart failure self-care over time.

METHOD

Latent mixture analysis was used to identify subgroups based on physical symptoms of dyspnea, sleepiness and edema (using the heart failure somatic perception and Epworth sleepiness scales). Growth modeling was used to determine if symptom subgroups were associated with self-care behaviors (using the self-care in heart failure index) over 6 months. Sociodemographic and clinical variables predicting the likelihood of subgroup membership were identified using logistic regression.

RESULTS

The sample ( n=146) was on average 57 years old, 70% were men and 59% had class III/IV heart failure. Two symptom subgroups were identified (entropy 0.91): a high symptom group ( n=24; 16%) with no significant change in symptoms over time (high sustained), and a low symptom group ( n=122; 84%) with no significant change in symptoms over time (low sustained). The high sustained group was associated significantly with better self-care behaviors at baseline and over 6 months. Women (odds ratio (OR) 3.67, P=0.023) and patients with more depressive symptoms (OR 1.16, P=0.015) were more likely to be in the high sustained symptom group. Those treated with a renin-angiotensin-aldosterone system agent were less likely to be in the high symptom group (OR 0.17, P=0.015).

CONCLUSION

Patients bothered more by symptoms are consistently more engaged in self-care behaviors over time. The results of this study support symptoms as an important driver of self-care behaviors.

Association of brain-derived neurotrophic factor and interleukin-6 serum levels with depressive and anxiety symptoms in hemodialysis patients

OBJECTIVE

This study assessed the possible association of serum brain-derived neurotrophic factor (BDNF) and interleukin-6 (IL-6) with depressive and anxiety symptoms in hemodialysis (HD) patients.

METHOD

An analytical cross-sectional study was conducted over 274 HD patients from March to October 2017. The Hospital Anxiety and Depression Scale (HADS) was utilized to evaluate depressive (HADS-D) and anxiety (HADS-A) symptoms. The HADS-D/A is a self-report instrument that has a maximum score of 21. Serum BDNF and IL-6 were measured using enzyme-linked immunosorbant assay (ELISA).

RESULTS

Serum IL-6 was significantly higher in patients with depressive symptoms compared to normal (20.47 ± 4.27 pg/mL for HADS-D ≥11 versus 9.26 ± 1.59 pg/mL for HADS-D <7, p = 0.014). Multivariable regression analysis revealed that IL-6, education level, hypertension, and dialysis duration were significant predictors of HADS-D. Also, gender, education level, hypertension, and the number of dialysis sessions/week were significant predictors of HADS-A. Significant positive correlation was shown between HADS-D and IL-6 (r = 0.1729, p = 0.004).

CONCLUSION

Collectively, HD patients with depressive symptoms showed higher levels of IL-6, supporting previous findings that the circulating inflammatory mediator IL-6 can be used as a biomarker for prediction of depressive symptoms in HD patients. Further longitudinal or interventional studies are needed to further validate this association.

The influence of comorbid anxiety on the effectiveness of Cognitive Therapy and Interpersonal Psychotherapy for Major Depressive Disorder

BACKGROUND

Anxious depression is an important subtype of Major Depressive Disorder (MDD) defined by both syndromal (anxiety disorders) and dimensional (anxiety symptoms) criteria. A debated question is how anxiety affects MDD treatment. This study examined the impact of comorbid anxiety disorders and symptoms on the effectiveness of and dropout during Cognitive Therapy (CT) and Interpersonal Psychotherapy (IPT) for MDD.

METHODS

Depressed individuals were randomized to CT (n = 76) or IPT (n = 75). Outcome was depression severity measured with the Beck Depression Inventory-II (BDI-II) at the start of each therapy session, post treatment, and monthly up to five months follow-up. Anxiety disorders were assessed with the Structured Clinical Interview for DSM-IV Axis I disorders, (phobic) anxiety symptoms were assessed with Brief Symptom Inventory subscales.

RESULTS

Approximately one third of participants had a comorbid anxiety disorder. Comorbid anxiety disorders and anxiety symptoms were associated with less favorable depression change during IPT as compared to CT in the treatment phase, but not in the trial follow-up phase. Individuals with a comorbid anxiety disorder had significantly higher treatment dropout during both treatments.

LIMITATIONS

Not all therapists and participants were blind to the assessment of comorbid anxiety disorders and the assessments were performed by one rater.

CONCLUSIONS

A preference for CT over IPT for MDD is justifiable when comorbid anxiety is present, although long-term differences are not established and replication of this finding is needed. Clinicians should be aware of the risk of dropout for depressed individuals with an anxiety disorder.

Psychopathological Dimensions in Portuguese Subjects with Transthyretin Familial Amyloid Polyneuropathy

Background

Transthyretin familial amyloid polyneuropathy (TTR-FAP) is a fatal, chronic, progressive disease. It is a rare hereditary amyloidosis, which manifests as a sensorimotor neuropathy and autonomic dysfunction. It begins during adulthood.

Aims and Methods

Our aim is to evaluate psychopathological dimensions in a population attending a consultation center for TTR-FAP. Two hundred and nine subjects (symptomatic and asymptomatic carriers), 84 men and 127, women participated in the study. Most subjects were married (67.1%) and most of them were still working; 33% were retired from work or on a sick leave. A sociodemographic questionnaire and The Brief Symptom Inventory (BSI) were applied. Statistical analysis was performed (descriptive analysis, Mann-Whitney, Wilcoxon, and Spearman tests).

Results

The Global Symptom Index (GSI) was significantly higher in patients (p = 0.001). Considering GSI, 32.7% of total subjects were above the median for general population. When subgroups were evaluated, 25.6% of symptomatic carriers, 26.3% of subjects without established diagnosis, and 39.1% of patients were above median. GSI was significantly higher in patients (p = 0.001). Some BSI dimensions were also significantly higher in the patient group (somatization, depression, anxiety, and psychoticism) when compared with carriers. Women scored higher than men. Sick women scored higher for all dimensions except somatization. Asymptomatic carriers scored statistically higher for phobic anxiety (p = 0.01), interpersonal sensitivity, anxiety, and depression. In patients, most dimensions and GSI (rho = 0.33, p = 0.002) had positive correlations with years of disease.

Conclusions

TTR-FAP patients and carriers are a very vulnerable group for psychological distress and psychopathological problems. Women and patients are at higher risk.

Cardiovascular Disease Risk Predicts Health Perception in Prison Inmates

We hypothesized that risk factors for cardiovascular disease (CVD) would be associated with worse health perceptions in prison inmates. This study included 362 inmates recruited from four medium security prisons in Kentucky. Framingham Risk Score was used to estimate the risk of developing CVD within the next 10 years. A single item on self-rated health from the Medical Outcomes Survey–Short Form 36 was used to measure health perception. Multinomial logistic regression showed that for every 1-unit increase in Framingham Risk Score, inmates were 23% more likely to have rated their health as fair/poor and 11% more likely to rate their health as good rather than very good/excellent. These findings demonstrate that worse health perceptions may serve as a starting point for discussing cardiovascular risk factors and prevention with inmates.

Psychometric Properties of the Multidimensional Scale of Perceived Social Support in Patients With Heart Failure

BACKGROUND AND PURPOSE

Low social support is associated with worse outcomes in patients with heart failure. Thus, the purpose of this study was to examine the reliability and validity of the Multidimensional Scale of Perceived Social Support (MSPSS).

METHODS

We performed a secondary analysis of registry data from patients (n = 475) with confirmed heart failure.

RESULTS

The MSPSS demonstrated excellent internal consistency reliability. Factor analysis yielded 3 factors that explained 83% of the variance in perceived social support. More than half of the sample had depressive symptoms (56%). Hypothesis testing demonstrated that worse perceived social support was a predictor of depressive symptoms.

CONCLUSION

The MSPSS is a reliable and valid instrument to measure perceived social support in patients with heart failure.

Friendship Attachment Style Moderates the Effect of Adolescent Exposure to Violence on Emerging Adult Depression and Anxiety Trajectories

Exposure to violence during adolescence is associated with increased risk behaviors and mental health problems in adulthood. Friendship attachment during adolescence may, however, mitigate the negative effects of exposure to violence on trajectories of depression and anxiety in young adulthood. In this study, we used growth curve modeling to examine associations between exposure to violence and mental health outcomes, followed by multi-group analyses with friendship attachment as the moderator. The sample was drawn from a longitudinal study (12 waves; 1994-2012) of 676 (54% female) urban high school students. We found strong positive associations between exposure to violence during adolescence and later self-reported depressive and anxiety symptoms. Notably, securely attached adolescents reported faster decreases in mental health symptoms as a function of violence relative to their insecurely attached peers as they transitioned into adulthood.

Factors associated with telemonitoring use among patients with chronic heart failure

Background In adults with chronic heart failure (HF; defined as people with previously diagnosed left ventricular dysfunction) telemonitoring randomized controlled trials (RCTs) failed to consistently demonstrate improved clinical outcomes. We aimed to examine if patient and HF characteristics are associated with device preferences and use. Methods Using a cross-sectional, multicenter, international design, ambulatory and hospitalized adults with HF in Ohio, California, and Denmark viewed a six-minute video of telemonitoring configurations (tablet, smart phone, and key fob) and completed questionnaires. Comparative analyses were performed and when significant, pairwise comparisons were performed using Bonferroni-adjusted significance levels. Results Of 206 participants, 48.2% preferred smart phones for telemonitoring, especially when traveling (54.8%), with new/worsening symptoms (50%), for everyday use (50%), and connecting with doctors (48.5%). Participants preferred two-way communication and a screen with words over voice or number pads. Of device purposes, allowing for nurse communication ranked highest, followed by maintaining overall health. Very few patient and HF factors were associated with device preferences. Patients with higher health literacy ( p = 0.007), previous/current device use history ( p = 0.008), higher education level ( p = 0.035), and married/cohabitating status ( p = 0.023) had higher perceptions of ease of using devices. Those who were asymptomatic or had mild HF had higher self-confidence for health devices ( p = 0.024) and non-white patients perceived devices as more useful ( p = 0.033). Conclusion Telemonitoring use may be enhanced by simple plug-and-play type devices, two-way communication, and features that meet patients' personal learning and use needs.

Physical and psychological symptom biomechanics in moderate to advanced heart failure

BACKGROUND

There is a common dissociation between objective measures and patient symptomatology in heart failure (HF).

OBJECTIVE

The aim of this study was to explore the relationship between cardiac biomechanics and physical and psychological symptoms in adults with moderate to advanced HF.

METHODS

We performed a secondary analysis of data from 2 studies of symptoms among adults with HF. Stepwise regression modeling was performed to examine the influence of cardiac biomechanics (left ventricular internal diastolic diameter, right atrial pressure [RAP], and cardiac index) on symptoms.

RESULTS

The average age of the sample (n = 273) was 57 ± 16 years, 61% were men, and 61% had class III or IV HF. Left ventricular internal diastolic diameter (β = 4.22 ± 1.63, P = .011), RAP (β = 0.71 ± 0.28, P = .013), and cardiac index (β = 7.11 ± 3.19, P = .028) were significantly associated with physical symptoms. Left ventricular internal diastolic diameter (β = 0.10 ± 0.05, P = .038) and RAP (β = 0.03 ± 0.01, P = .039) were significantly associated with anxiety. There were no significant biomechanical determinants of depression.

CONCLUSION

Cardiac biomechanics were related to physical symptoms and anxiety, providing preliminary evidence of the biological underpinnings of symptomatology among adults with HF.

Associations between anxiety and depression symptoms and cognitive testing and neuroimaging in type 2 diabetes

AIMS

Anxiety, depression, accelerated cognitive decline, and increased risk of dementia are observed in individuals with type 2 diabetes. Anxiety and depression may contribute to lower performance on cognitive tests and differences in neuroimaging observed in individuals with type 2 diabetes.

METHODS

These relationships were assessed in 655 European Americans with type 2 diabetes from 504 Diabetes Heart Study families. Participants completed cognitive testing, brain magnetic resonance imaging, the Brief Symptom Inventory Anxiety subscale, and the Center for Epidemiologic Studies Depression-10.

RESULTS

In analyses adjusted for age, sex, educational attainment, and use of psychotropic medications, individuals with comorbid anxiety and depression symptoms had lower performance on all cognitive testing measures assessed (p≤0.005). Those with both anxiety and depression also had increased white matter lesion volume (p=0.015), decreased gray matter cerebral blood flow (p=4.43×10(-6)), decreased gray matter volume (p=0.002), increased white and gray matter mean diffusivity (p≤0.001), and decreased white matter fractional anisotropy (p=7.79×10(-4)). These associations were somewhat attenuated upon further adjustment for health status related covariates.

CONCLUSIONS

Comorbid anxiety and depression symptoms were associated with cognitive performance and brain structure in a European American cohort with type 2 diabetes.

The association of co-morbid symptoms of depression and anxiety with all-cause mortality and cardiac rehospitalization in patients with heart failure

BACKGROUND

Patients with heart failure (HF) experience multiple psychologic symptoms. Depression and anxiety are independently associated with survival. Whether co-morbid symptoms of anxiety and depression are associated with outcomes in patients with HF is unknown.

OBJECTIVE

To determine whether co-morbid symptoms of depression and anxiety are associated with all-cause mortality or rehospitalization for cardiac causes in patients with HF.

METHOD

A total of 1260 patients with HF participated in this study. Cox regression analysis was used to determine whether co-morbid symptoms of depression and anxiety independently predicted all-cause mortality and cardiac rehospitalization. Anxiety and depression were treated first as continuous-level variables, then as categorical variables using standard published cut points. Patients were then divided into 4 groups based on the presence of anxiety and depression symptoms.

RESULTS

When entered as a continuous variable, the interaction between anxiety and depression (hazard ratio = 1.02; 95% CI: 1.01-1.03; p = 0.002) was a significant predictor of all-cause mortality in patients with HF. When entered as a categorical variable, co-morbid symptoms of depression and anxiety (vs no symptoms or symptoms of anxiety or depression alone) independently predicted all-cause mortality (hazard ratio = 2.59; 95% CI: 1.49-4.49; p = 0.001). None of the psychologic variables was a predictor of cardiac rehospitalization in patients with HF whether using the continuous or categorical level of measurement.

CONCLUSION

To improve mortality outcomes in patients with HF, attention must be paid by health care providers to the assessment and management of co-morbid symptoms of depression and anxiety.

Examination of the potential association of stress with morbidity and mortality outcomes in patient with heart failure

Objectives:

The high mortality and morbidity rates associated with heart failure are still not well explained. A few psychosocial factors have been studied and explain some of this risk, but other factors, like stress, remain largely unexplored in heart failure. This study aimed to (1) examine the association of stress with 6-month cardiac event-free survival, (2) examine the relationship of stress with salivary cortisol, and (3) examine the association of salivary cortisol level with 6-month cardiac event-free survival.

Method:

A total of 81 heart failure patients participated. Stress was measured using the brief Perceived Stress Scale. Cortisol was measured from unstimulated whole expectorated saliva. Cox regression analyses were used to determine whether stress predicted event-free survival, and if salivary cortisol predicted event-free survival. Linear and multiple regressions were used to determine the association of stress with salivary cortisol.

Results:

Stress was not a significant predictor of event-free survival in heart failure (heart rate = 1.06; 95% confidence interval = 0.95–1.81; p = 0.32). Salivary cortisol was a significant predictor of event-free survival in the unadjusted model (heart rate = 2.30; 95% confidence interval = 0.99–5.927; p = 0.05), but not in the adjusted model. Stress (β 1.06; 95% confidence interval = 0.95–1.18; p = 0.32) was not a significant predictor of salivary cortisol level.

Conclusion:

Stress is a complex phenomenon, and our measure of stress may not have captured it well. Alternatively, the physical stressors acting in heart failure produce levels of neurohormonal activation that mask the effects of psychosocial stressors or an indirect association of stress with outcomes that is mediated through another construct. Future studies are needed to investigate stress in patients with heart failure to provide definitive answers.

Development and psychometric evaluation of the Chronic Kidney Disease Screening Index

OBJECTIVE

Public understanding of chronic kidney disease (CKD) is important to ensure informed participation in CKD prevention programs. This study aimed to develop and to test the psychometric profile of the CKD Screening Index that measures patient's knowledge, attitudes, and practices regarding CKD prevention and early detection.

METHODS

A cross-sectional design was implemented and a total of 740 Jordanian patients recognized at risk for CKD were recruited by convenience sampling from out-patient departments. Development and psychometric validation of the CKD Screening Index were conducted in four phases: (1) item generation, (2) pilot study, (3) preliminary psychometric validation study to examine factor structure, and (4) final psychometric validation with 740 participants.

RESULTS

On factor analysis, 24 items categorical knowledge items loaded into one factor and yielded a Guttman Split-Half Coefficient of 0.80. In a separate factor analysis, 15 items were loaded on two attitude factors (Cronbach alpha coefficient = 0.69), and nine items loaded on two practice factors (Cronbach alpha coefficient = 0.68). The CKD Screening Index associated significantly and negatively with depressed and anxious patients compared to their counterparts.

PRACTICE IMPLICATIONS

This promising CKD Screening Index can be used for an early identification of patients at risk for CKD, thus, allowing the development of interventions to raise these patients' awareness. Future studies are needed on other populations with different cultural background to support reliability and validity of this new instrument.

Perceived social support is a partial mediator of the relationship between depressive symptoms and quality of life in patients receiving hemodialysis

BACKGROUND

The meaning of social support is well documented, but less is known about mediating characteristics that examine which patients with end stage renal disease (ESRD) and depressive symptoms are most likely to benefit.

AIMS

The aim of this study was to examine whether perceived social support mediated depressive symptoms on the outcome of quality of life (QoL).

DESIGN

A correlational, cross-sectional study was conducted with a convenience sampling of 190 patients with ESRD.

RESULTS

There was partial mediation effect of social support on depressive symptoms in the prediction of QoL.

CONCLUSION

Effective management of depressive symptoms will improve QoL mostly when social support is promoted in patients with ESRD receiving hemodialysis.

Coexisting anxiety and depressive symptoms in patients with heart failure

BACKGROUND

Among patients with heart failure (HF), anxiety symptoms may co-exist with depressive symptoms. However, the extent of overlap and risk factors for anxiety symptoms have not been thoroughly described.

PURPOSE

The aim of this study was to describe the coexistence of anxiety and depressive symptoms, and to determine the predictors of anxiety symptoms in patients with HF.

METHODS

The sample consisted of 556 outpatients with HF (34% female, 62±12 years, 54% New York Heart Association (NYHA) class III/IV) enrolled in a multicenter HF quality of life registry. Anxiety symptoms were assessed with the Brief Symptom Inventory-anxiety subscale. Depressive symptoms were measured with the Beck Depression Inventory-II (BDI). We used a cut-point of 0.35 to categorize patients as having anxiety symptoms or no anxiety symptoms. Logistic regression was used to determine whether age, gender, minority status, educational level, functional status, comorbidities, depressive symptoms, and antidepressant use were predictors of anxiety symptoms.

RESULTS

One-third of patients had both depressive and anxiety symptoms. There was a dose-response relationship between depressive symptoms and anxiety symptoms; higher levels of depressive symptoms were associated with a higher level of anxiety symptoms. Younger age (odds ratio (OR)= 0.97, p=0.004, 95% confidence interval (CI) 0.95-0.99) and depressive symptoms (OR =1.25, p<0.001, 95% CI 1.19-1.31) were independent predictors of anxiety symptoms.

CONCLUSIONS

Patients with HF and depressive symptoms are at high risk for experiencing anxiety symptoms. Clinicians should assess these patients for comorbid anxiety symptoms. Research is needed to test interventions for both depressive and anxiety symptoms.

Being white helps: intersections of self-concealment, stigmatization, identity formation, and psychological distress in racial and sexual minority women

This study had two objectives: (1) examine the impact of self-concealment on identity formation and on degree of psychological distress and (2) examine the impact of perceived stigma on identity formation and on degree of psychological distress. Analyses were conducted on a diverse sample of 166 women, ages 18-32 (white lesbian, non-white lesbian, white heterosexual, and non-white heterosexual). Findings revealed that self-concealment was positively associated with psychological distress in stigmatized women, but unrelated to psychological distress in the non-stigmatized group. Furthermore, although perceived stigma negatively impacted identity formation in the heterosexual groups, it did not impact either group of lesbians. Finally, non-white heterosexual women's perception of stigma was associated with psychological distress. Implications and specific psychological health disparities between groups are discussed.

Medication adherence, depressive symptoms, and cardiac event-free survival in patients with heart failure

BACKGROUND

Medication nonadherence and depressive symptoms predict hospitalization and death in patients with heart failure (HF). Depressed patients have lower medication adherence than nondepressed patients. However, the predictive power of the combination of medication adherence and depressive symptoms for hospitalization and death has not been investigated in patients with HF.

OBJECTIVE

The aim of this study was to explore the combined influence of medication adherence and depressive symptoms for prediction of cardiac event-free survival in patients with HF.

METHODS AND RESULTS

We monitored medication adherence in 216 HF patients who completed the Patient Health Questionnaire-9 (PHQ-9) at baseline. Medication adherence was measured objectively with the use of the Medication Event Monitoring System (MEMS). Patients were followed for up to 3.5 years to collect data on cardiac events. Survival analyses were used to compare cardiac event-free survival among groups. The risk of experiencing a cardiac event for patients with medication nonadherence and depressive symptoms was 5 times higher than those who were medication adherent without depressive symptoms. The risk of experiencing a cardiac event for patients with only 1 risk factor was 1.2-1.3 times that of those with neither risk factor.

CONCLUSIONS

Medication nonadherence and depressive symptoms had a negative synergistic effect on cardiac event-free survival in patients with HF.

Knowledge is insufficient for self-care among heart failure patients with psychological distress

OBJECTIVE

We conducted a study to identify barriers to, and factors promoting, self-care among heart failure (HF) patients with higher or lower levels of knowledge.

METHOD

Baseline data from 612 patients with HF enrolled in the REMOTE-HF trial were analyzed. Using median splits on the HF Knowledge Scale and the European HF Self-Care Behavior Scale, patients were divided into four groups: (a) low knowledge and good self-care, (b) low knowledge and poor self-care, (c) high knowledge and good self-care, and (d) high knowledge and poor self-care. Characteristics of the groups were compared using ANOVA, Kruskal-Wallis tests, and chi-square tests, followed by pairwise tests with Bonferroni correction. Variables significant in the univariate analyses were evaluated as predictors of self-care using hierarchical multiple linear regression. The potential moderating effect of knowledge was tested with interaction terms.

RESULTS

The four groups did not differ in sociodemographics or health literacy scores, but differed in New York Heart Association (NYHA) class, comorbidities, and scores on depression, anxiety, and perceived control. In post hoc pairwise tests, patients with high knowledge and poor self-care tended to have worse NYHA class, greater depression and anxiety, and lower levels of perceived control than others. In the multivariate analysis, knowledge, depressive symptoms, and perceived control were significant predictors of self-care, as was the interaction between knowledge and anxiety.

CONCLUSIONS

Screening and treatment of depression and anxiety is important in improving self-care among HF patients. HF management programs need to include strategies for increasing patients' perceived control over their heart disease.
