Failure to consult for symptoms of heart failure in patients with a type-D personality

Cardio SEM: A Novel Approach for a Traffic Light System for Heart Failure Warning Signs

Existing literature on the follow-up of heart failure patients with warning signs shows that it is necessary to increase patients' knowledge and of seeking help in a timely manner. This suggests an opportunity to implement strategies that integrate technology to visualize the risk of decompensation. This article studies the acceptance of Cardio Sem, a traffic light system mobile application for patients with heart failure. A descriptive, observational pilot study was performed with 23 outpatients belonging to a heart failure program. For 4 weeks, patients used Cardio Sem, which allows visualizing the risk of decompensation through a series of questions that patients must answer daily and provides guidance for managing signs and symptoms of decompensation. A technology acceptance questionnaire was applied to all patients, resulting in acceptance of the application, especially in the dimensions that emphasized perceived usefulness (100%), social influence (100%), and behavioral intent (99.8%). Cardio Sem is useful for early detection of symptoms that allow for early response to complications. Acceptance of the application by patients and its ease of use present the possibility to implement it as a complementary tool to promote self-care and effective management of symptoms.

Relationship between Functional Status and Type D Personality and Psychiatric Symptoms of Patients with Chronic Obstructive Pulmonary Disease (COPD)

Emotional difficulties, adjustment difficulties, anxiety disorder, paranoid reactions and depression are among the common psychiatric disorders in patients with Chronic Obstructive Pulmonary Disease (COPD). Type D personality is characterized by social inhibition and negative affectivity. Individuals with Type D personality have difficulty in coping with chronic diseases. The aim of our study was to determine type D personality and psychiatric symptoms in patients with COPD. A patient group was formed with 44 people hospitalized with COPD in the Chest Diseases service and a control group was formed with 44 healthy people. A sociodemographic data form, the Beck Depression Inventory, State and Trait Anxiety Inventory, Somatosensory Amplification Scale, Type D Personality Scale, and BODE (Body mass index, Obstruction, Dyspnea, Exercise capacity) index, were used to. According to the results of our study, state and trait anxiety, depression and D-type personality, exaggeration of bodily sensations scale scores were statistically significantly higher in the patient group compared to the control group. Moreover, a high score on the somatosensory amplification scale and having a type D personality were correlated with the BODE index score. These results suggest that it is important for patients with COPD to be examined by a psychiatrist..

A Controlled Community Study of Distress and Resilience in Women Diagnosed with Fibromyalgia and Systemic Lupus Erythematosus

This study examines psychological and physical influences on the distress and well-being of patients with chronic rheumatic diseases. The study aims were to (1) evaluate the relative contribution of objective disease activity and psychological factors on the wellbeing of patients with systemic lupus erythematosus (SLE); (2) to compare the psychological distress of SLE patients to fibromyalgia (FM) patients and healthy controls, and to (3) characterize subgroups of patients by performing cluster analysis using psychological variables. Participants were ascertained from closed forums and social media channels resulting in 41 women with a diagnosis of SLE, 47 with a diagnosis of FM, and 77 healthy controls (HC). Hierarchical linear regression for well-being of SLE patients found that most of the variance was accounted for by social support. Cluster analysis performed on the entire sample identified two clusters, a distressed group tending to Type D personality, anxiety and depression, low in well-being and social support, and a resilient group; the proportion of resilient individuals was highest in the HC intermediate in the SLE group and lowest in the FM group. The importance of psychological variables vs disease severity in these two rheumatic diseases for wellbeing is demonstrated by these results. The results suggest that psychological interventions that enhance the experience of social support in medical settings, might benefit patients with both diseases, and be of particular importance to the well-being of patients who are more distressed.

Understanding Patient Personality in Medical Care: Five-Factor Model

Personality is the description of an individual's tendencies when acting or reacting to others. Clinicians spontaneously form impressions of a patient's apparent personality yet such unstructured impressions might lead to snap judgments or unhelpful labels. Here we review the evidence-based five-factor model from psychology science for understanding personalities (OCEAN taxonomy). Openness to experience is defined as the general appreciation for a variety of experiences. Conscientiousness is the tendency to exhibit self-discipline. Extraversion is the degree of engagement with the external world. Agreeableness is the general concern for social harmony. Neuroticism is the tendency to experience negative emotions. An awareness of these five dimensions might help clinicians avoid faulty judgments from casual contact. Expert assessment of personality requires extensive training and data, thereby suggesting that clinicians should take a humble view of their own unsophisticated impressions of a patient's personality.

The Influence of Personality Type D on Cardiovascular Prognosis in Patients After Coronary Artery Bypass Grafting: Data from a 5-Year-Follow-up Study

BACKGROUND

Type D personality is accompanied by a set of negative behavioral patterns: low physical activity, high levels of psychological distress, low adherence to treatment. However, studies regarding predictive value of the type D personality remain inconclusive: the results varied depending on the examined cohort, age, and ethnicity. The aim of the study was to evaluate the influence of type D personality on the 5-year prognosis in patients undergoing coronary artery bypass grafting (CABG) in Russian population.

METHODS

The study included 602 patients with stable coronary artery disease (490 males, 57.7 ± 7.3 years) who had received CABG and were divided into two groups: patients with type D personality (n = 134) and patients without type D (n = 468). The risk of fatal and nonfatal events within 5 years after CABG was assessed.

RESULTS

There was no difference in total mortality in patients with type D and without type D (7.9% and 7.7%, respectively) over the 5-year period. The absence of cardiac events was detected much less frequently in patients with type D (28%) compared with patients without type D (82%; p = 0.021). Multivariate analysis found independent association between the unfavorable outcome and presence of diabetes mellitus (p = 0.021), type D personality (p = 0.039), and multifocal atherosclerosis (p = 0.033) regardless of gender, age, previous myocardial infarction, and stroke.

CONCLUSIONS

Type D patients had a greater risk for cardiac events over 5 years after CABG compared with non-type D patients. Obtained data indicates that it is reasonable to consider personality type while detecting patients at risk of development of stress induced cardiac complications after CABG.

Psychosocial phenotyping as a personalization strategy for chronic disease self-management interventions

BACKGROUND

As the U.S. population grows older and more diverse, self-management needs are increasingly complicated. In order to deliver effective personalized interventions to those suffer from chronic conditions social determinants of health must be considered. Therefore, psychosocial phenotyping holds strong promise as a tool for tailoring interventions based on precision health principles.

PURPOSE

To define psychosocial phenotyping and develop a research agenda that promotes its integration into chronic disease management as a tool for precision self-management interventions.

METHODS

Since psychosocial phenotyping is not yet used in interventions for self-management support, we conducted a literature review to identify potential phenotypes for chronic disease self-management. We also reviewed policy intervention case reports from the Centers for Medicare and Medicaid Services to examine factors related to social determinants of health in people with chronic illnesses. Finally, we reviewed methodological approaches for identifying patient profiles or phenotypes.

RESULTS

The literature review revealed areas within which to collect data for psychosocial phenotyping that can inform personalized interventions. The findings of our exemplar cases revealed that several environmental or key SDOH such as factors realted with economic stability and neighborhood environment have been closely linked with the success of chronic disease management interventions. We elucidated theory, definitions, and pragmatic conceptual boundaries related to psychosocial phenotyping for precision health.

CONCLUSIONS

Our literature review with case example analysis demonstrates the potential usefulness of psychosocial phenotyping as a tool to enhance personalized self-management interventions for people with chronic diseases, with implications for future research.

The impact of type D personality on self-care of patients with type 2 diabetes: the mediating role of coping strategies

PURPOSE

As a chronic disease, Diabetes requires special self-care behaviors until the end of life. Psychological factors play an important role in following the self-care plans among patients with diabetes. The present study was designed to examine the relationship between type D personality and self-care with the mediating role of coping strategies in patients with type 2 diabetes.

METHODS

This cross-sectional study was carried out on a sample of 361 patients with type 2 diabetes from Ale-Ebrahim Diabetes Charity Center in Isfahan, Iran. Type D personality, coping strategies and self-care were measured by validated questionnaires. The data were analyzed through Structural Equation Modeling (SEM).

RESULTS

The results indicated that type D personality affects the self-care behaviors indirectly via emotion-oriented coping. Problem and avoidant oriented coping strategies did not significantly mediate the effect of type D personality on self-care.

CONCLUSION

In general, assessing psychological background (such as personality traits and coping strategies) can facilitate the treatment of patients with diabetes by means of self-care enhancement.

Social inhibition and approach-avoidance tendencies towards facial expressions

This study examined how different manifestations of social inhibition (behavioral inhibition, interpersonal sensitivity, and social withdrawal) are related to automatic approach/avoidance behaviors in a social context. A sample of 115 undergraduate students and 20 adults from the general population (M_age = 24.8, SD = 11.4; 75% women) were assessed with the 15-item Social Inhibition Questionnaire (SIQ15). During a facial expression version of the Approach-Avoidance Task (AAT), participants reacted to images of emotional facial expressions (angry, happy, and neutral) or to control images (neutral objects) in portrait or landscape formats by pulling a joystick towards themselves (approach) or pushing it away from themselves (avoidance). The superordinate social inhibition construct was not associated with approach/avoidance tendencies. However, individuals high in the interpersonal sensitivity domain of social inhibition showed stronger approach tendencies for happy and neutral facial expressions compared to neutral objects, which may relate to their focus on seeking the approval of others.

The mediating effect of resilience on the relationship between Type D personality and self-care behavior in patients with heart failure

AIM

There have been few studies done looking at the relationship between resilience, Type D personality, and self-care behavior in patients with heart failure. The purpose of this study was to identify the mediating effect of resilience on the relationship between Type D personality and self-care behavior in patients with heart failure.

METHODS

The subjects consisted of a sample of 90 heart failure patients aged ≥20 years who visited the cardiology outpatient clinic in the Chungbuk area of South Korea.

RESULTS

Among 90 patients, 49 subjects (54.0%) were classified as Type D personality, who exhibited statistically significant differences in resilience and self-care behavior (p < .001). A statistically significant correlation was also observed between self-care behavior score and resilience score (p < .01). The resilience had full mediation effects on the relationship between Type D personality and self-care behavior. In other words, the higher their resilience, the better their self-care behavior.

CONCLUSIONS

The study showed that resilience and Type D personality have important effects on self-care behavior.

Self-Care and Pathophysiological Function in Patients with Chronic Heart Failure

Background

Self-care is assumed to benefit physiological function associated with prognosis in patients with chronic HF, but studies examining these relations are lacking. This study aims to prospectively examine the association of self-reported HF self-care with HF-associated pathophysiological markers, including renal, hematological, and immune function.

Method

Patients with chronic HF (n = 460, 66.2 ± 9.6 years, 75% men) completed questionnaires and provided blood samples at baseline and 12-month follow-up. Linear mixed models examined random intercept and fixed between- and within-subjects effects of global self-care and the individual self-care behaviors on log-transformed TNF-α, IL-6, and IL-10, the glomerular filtration rate of creatinine (GFR_creat), and hemoglobin (Hb), controlling for sociodemographic and clinical covariates.

Results

Self-care was independently associated with lower GFR_creat levels (β = − .14, P = .023) and improvement in self-care with a reduction in GFR_creat (β = − .03, P = .042). Individual self-care behaviors were differentially associated with renal, inflammatory, and hematological markers. Regular exercise was associated with level differences in IL-6 (P < .001), and improvement in exercise was associated with increasing GFR_creat (P = .002) and increasing Hb (P = .010). Fluid restriction was associated with lower overall GFR_creat (P = .006), and improvement in fluid restriction was associated with decreasing GFR_creat (P = .014). Low-sodium intake was associated with lower levels of Hb (P = .027), lower TNF-alpha (P = .011), and lower IL-10 (P = .029). Higher levels of medication adherence were associated with reduced pro-inflammatory activation (P < .007).

Conclusion

Our findings suggest that better global self-care was associated with poorer renal function. Performing self-care behaviors such as regular exercise and medication adherence was associated with improved physiological functioning, while restriction of fluid and sodium, and the associated daily weight monitoring were associated with adverse levels of pathophysiological biomarkers.

Type D Personality, Concomitant Depressive and Anxiety Disorders, and Treatment Outcomes in Somatic Symptom and Related Disorders: An Observational Longitudinal Cohort Study

Objective: To establish the prevalence of Type D personality in patients with somatic symptoms and related disorders and to evaluate the association of Type D personality with treatment outcomes. This study explores the effect of Type D personality and its two traits, negative affectivity (NA) and social inhibition (SI). Methods: In this longitudinal observational cohort study, we assessed the prevalence of Type D in 212 patients presenting themselves at a clinic in Tilburg, the Netherlands. We explored psychological and physical treatment outcomes of a multimodal treatment tailored to patient needs in relation to Type D scores. We explored the differences with regard to physical symptoms, anxiety, and depression. We also explored the differences between patients with and without Type D personality who completed treatment with regard to the baseline scores of physical symptoms, anxiety, and depression. We explored the association between Type D personality and treatment outcome using the traditional dichotomous method and the dimensional method (with main effects of NA and SI, and the interaction of NA × SI). Results: Of the 212 patients with Somatic Symptom and Related Disorders (SSRD), those with Type D personality (181: 61.8%) had experienced significantly higher levels of depression [t = 4.404, p < .001] and anxiety [t = 3.757, p < .001]. Of the 212, 187 patients completed treatment. Mean scores improved significantly for the whole patient group after treatment with regard to depression (p < .001), anxiety (p < .001), and physical symptoms (p < .001). At baseline, patients with Type D personality had significantly higher scores in anxiety [F = 15.707, p < .001] and depression [F = 19.392] than patients without Type D personality who completed treatment. After controlling for the high baseline scores with regard to physical symptoms, anxiety, or depression, only the effect of Type D personality on remission of anxiety was significant (OR = .33, p = 0.39). Neither NA and SI nor the interaction of NA × SI was associated with the treatment outcome. Conclusions: This study shows that Type D personality occurs frequently in patients with SSRD. Type D personality only decreases the probability of remission of anxiety as a treatment outcome, and both NA and SI play a role in this. Type D personality did not decrease remission either of physical symptoms or of depression. Hence, both NA and SI factors may be expressions of anxiety mostly in type D.

Mortality in unipolar depression preceding and following chronic somatic diseases

OBJECTIVE

It is largely unknown how depression prior to and following somatic diseases affects mortality. Thus, we examined how the temporal order of depression and somatic diseases affects mortality risk.

METHOD

Data were from a Danish population-based cohort from 1995 to 2013, which included all residents in Denmark during the study period (N = 4 984 912). Nineteen severe chronic somatic disorders from the Charlson Comorbidity Index were assessed. The date of first diagnosis of depression and somatic diseases was identified. Multivariable Cox proportional Hazard models with time-varying covariates were constructed to assess the risk for all-cause and non-suicide deaths for individual somatic diseases.

RESULTS

For all somatic diseases, prior and/or subsequent depression conferred a significantly higher mortality risk. Prior depression was significantly associated with a higher mortality risk when compared to subsequent depression for 13 of the 19 somatic diseases assessed, with the largest difference observed for moderate/severe liver disease (HR = 2.08; 95% CI = 1.79-2.44), followed by metastatic solid tumor (HR = 1.48; 95% CI = 1.39-1.58), and myocardial infarction (HR = 1.40; 95% CI = 1.34-1.49).

CONCLUSION

A particularly high mortality risk was observed in the presence of prior depression for most somatic diseases. Future studies that assess the underlying mechanisms are necessary to adequately address the excessive mortality associated with comorbid depression.

Role of personality in cardiovascular diseases: An issue that needs to be focused too!

This review provides a broad overview of the relationship of personality with cardiovascular diseases (CVDs). There has been a sustained interest over the last half a century on the issue of relationship between personality traits and CVDs. Type A behavior was the initial focus of inquiry as it was observed that individuals who were competitive, hostile, and excessively driven were overrepresented among patients seeking treatment for CVDs and also were prone to develop coronary artery disease/syndrome. However, the research gradually expanded to assess the relationship of cardiac morbidity with various other personality facets. Furthermore, studies found out that negative effects (including anger and hostility) were also associated with adverse cardiovascular outcomes. Subsequently, a new personality entity named as the type D ‘distressed’ personality, which combined negative affectivity and social inhibition. type D personality then became the area of research and was demonstrated to be related with poorer cardiac outcomes. Interestingly, the results of various research studies are not equivocal, and hence, there are several critiques related to the current understanding of the link between personality construct and the risk of development as well as the outcome of CVDs. Furthermore, few personality traits such as optimism, conscientiousness, openness to experience, and curiosity have been found to be protective factors against development of CVDs and therefore are called ‘cardioprotective’ personality traits. A detailed discussion on the various aspects of personality in relation to CVDs along with a critical appraisal has been presented in this review.

Type D personality and social relations in adults with diabetes: results from diabetes MILES - The Netherlands

OBJECTIVE

To examine whether individual differences in Type D personality (combination of negative affectivity (NA) and social inhibition (SI)) could explain heterogeneity in perceived social support and relationship adjustment (intimate partner relationship) among people living with diabetes.

DESIGN

In the Diabetes MILES-The Netherlands survey, 621 adults with type 1 or type 2 diabetes (54% female, age: 56 ± 14 years) completed measures of Type D personality (DS14), perceived social support and relationship adjustment. We used established DS14 cut-off scores to indicate Type D personality, high NA only, high SI only and reference groups.

RESULTS

Participants from the Type D and NA only groups perceived lower levels of social support (Welch[3,259] = 37.27, p < 0.001), and relationship adjustment (Welch[3,191] = 14.74; p < 0.01) than those from the SI only and reference groups. Type D was associated with lower social support (lowest quartile; adjusted OR = 8.73; 95%CI = 5.05 ∼ 15.09; p < 0.001) and lower relationship adjustment (lowest quartile; adjusted OR = 3.70; 95%CI = 2.10 ∼ 6.53; p < 0.001). Type D was also associated with increased levels of loneliness.

CONCLUSION

Participants with Type D and participants with high NA only tend to experience less social support and less relationship adjustment. Type D personality was also associated with more loneliness. Experiencing lower social support and relationship adjustment may complicate coping and self-management in people with diabetes.

An exploratory study of adolescent response to fluoxetine using psychological and biological predictors

Background

Not enough is known about predicting therapeutic response to serotonin-specific reuptake inhibitors, and specifically to fluoxetine. This exploratory study used psychological and biological markers for (retrospective) prediction of treatment-response to fluoxetine in depressed and/or anxious adolescents.

Methods

Forty-one consecutive adolescent outpatients with a primary diagnosis of severe affective and/or anxiety disorders were assessed and treated with an open-label 8-week trial of fluoxetine. Type D personality was assessed with the 14-item questionnaire, the DS14. In addition, TNFα, IL-6, and IL-1b were measured pre- and post-treatment.

Results

There was an elevation of Type D personality in patients, compared to the adolescent population rate. Post-treatment, 44% of patients were classified as non-responders; the relative risk of non-response for Type D personality patients was 2.8. Binary logistic regression predicting response vs. non-response showed a contribution of initial TNFα levels as well as Type D personality to non-response.

Conclusions

In this exploratory study, the most significant contributor to non-response was Type D personality. However, the measurement of Type D was not prospective, and thus may be confounded with psychiatric morbidity. The measurement of personality in psychiatric settings may contribute to the understanding of treatment response and have clinical utility.

Factors related to self-care behaviours in heart failure: A systematic review of European Heart Failure Self-Care Behaviour Scale studies

BACKGROUND

Self-care is an important element in the comprehensive management of patients with heart failure. The European Heart Failure Self-Care Behaviour Scale (EHFScBS) was developed and tested to measure behaviours performed by the heart failure patients to maintain life, healthy functioning, and wellbeing.

AIMS

The purpose of this review was to evaluate the importance of factors associated with heart failure self-care behaviours as measured by the EHFScBS.

METHODS

Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines were used to search major health databases (PubMed, Scopus and ScienceDirect). Obtained associating factors of heart failure self-care were qualitatively synthesised and the association levels of most commonly addressed factors were further explored.

RESULTS

We identified 30 studies that were included in the review; a diverse range of personal and environmental factors associated with self-care behaviours in heart failure patients were identified. Age, health-related quality of life, gender, education, New York Heart Association class, depressive symptoms and left ventricular ejection fraction were most often correlated with the EHFScBS score. Consistent evidence for the relationship between self-care behaviours and depression was found, while their association with New York Heart Association class and health-related quality of life was non-significant in most of the studies. Associations with other factors were shown to be inconsistent or need to be further investigated as they were only addressed in single studies.

CONCLUSION

A sufficient body of evidence is available only for a few factors related to heart failure self-care measured by the EHFScBS and indicates their limited impact on patient heart failure self-care. The study highlights the need for further exploration of relationships that would offer a more comprehensive understanding of associating factors.

Symptoms of Dry Eye Disease and Personality Traits

The essential targets of dry eye disease (DED) treatments include both objective signs and subjective symptoms. However, due to the numerous subjective symptoms, it is understandable why little association has been found between the signs and symptoms. Although psychological influences on the subjective symptoms have been reported, little is known about the influence of personality traits. The present study analyzed the relationship between the signs/symptoms of DED and the personality traits of patients using a cross-sectional design. We examined 56 DED patients (mean age; 62.4 ± 12.9, range 34–85 years) visiting the outpatient clinic of the Department of Ophthalmology at the Nippon Medical School Hospital in Tokyo, Japan. Objective signs evaluated included the Schirmer I test, tear breakup time (BUT), fluorescein and lissamine green staining, and tear osmolality. Subjective symptoms were assessed by the Ocular Surface Disease Index (OSDI) and Dry Eye-Related Quality-of-Life Score (DEQS) questionnaires. For personality traits, the Big Five personality traits model analysis was used. Correlations between the objective signs, subjective symptoms, and personality traits were analyzed. A significant correlation was found between the neuroticism in the Big Five Personality Inventory and the symptoms assessed by the DEQS (r = -0.35, p < 0.01), and the OSDI (r = -0.28, p < 0.05). There was no significant correlation observed between the signs and the symptoms, or between the signs and any personality traits. The results of our current study suggest that the personality of the patient, which appears to be the basis of various psychological factors, can have some impact on the subjective symptoms. This may be one of the reasons why there has been little association noted between the signs and symptoms of DED.

The moderation effect of personality on healthcare utilization in Chinese people living with HIV

There is evidence that Type D personality can predict impaired quality of life and health status in various chronic conditions. The evidence is conflicting as to whether Type D is associated with increased healthcare services, and no study has reported on the healthcare utilization of people living with HIV (PLWH) who have a Type D personality. This study investigated the impact of Type D personality on healthcare utilization in a sample of Chinese PLWH and examined physical and emotional symptoms as possible mechanisms of healthcare utilization. This was a cross-sectional study of 199 PLWH in rural China. Participants completed a survey on physical symptoms, emotional symptoms, healthcare utilization, and Type D personality. Those PLWH with a Type D personality reported more physical and emotional symptoms and healthcare utilization than patients without this personality. Among PLWH who had a Type D personality, physical symptoms had a direct effect on healthcare utilization, and emotional symptoms did not significantly mediate this association. However, among PLWH without a Type D personality, emotional symptoms significantly mediated the effects of physical symptoms on healthcare utilization. PLWH with a Type D personality reported more healthcare utilization, which was attributed to their high physical symptoms rather than their emotional symptoms. These findings suggest that PLWH with a Type D personality might be bothered by intensified emotional symptoms, which might be too severe to be associated with physical symptoms and healthcare utilization. New prospective studies should focus on the pattern of healthcare utilization among patients with a Type D personality and their intensified physical and emotional symptoms.

A Type A and Type D Combined Personality Typology in Essential Hypertension and Acute Coronary Syndrome Patients: Associations with Demographic, Psychological, Clinical, and Lifestyle Indicators

Many studies have focused on Type A and Type D personality types in the context of cardiovascular diseases (CVDs), but nothing is known about how these personality types combine to create new profiles. The present study aimed to develop a typology of Type A and Type D personality in two groups of patients affected by and at risk for coronary disease. The study involved 711 patients: 51.6% with acute coronary syndrome, 48.4% with essential hypertension (mean age = 56.4 years; SD = 9.7 years; 70.7% men). Cluster analysis was applied. External variables, such as socio-demographic, psychological, lifestyle, and clinical parameters, were assessed. Six groups, each with its own unique combined personality profile scores, were identified: Type D, Type A-Negatively Affected, Not Type A-Negatively Affected, Socially Inhibited-Positively Affected, Not Socially Inhibited, and Not Type A-Not Type D. The Type A-Negatively Affected cluster and, to a lesser extent, the Type D cluster, displayed the worst profile: namely higher total cardiovascular risk index, physical inactivity, higher anxiety and depression, and lower self-esteem, optimism, and health status. Identifying combined personality profiles is important in clinical research and practice in cardiovascular diseases. Practical implications are discussed.

Type D personality negatively associated with self-care in Chinese heart failure patients

BACKGROUND

Little is known about the association between type D personality and self-care behaviors in heart failure (HF) patients. We examined the effect of type D personality on self-care behaviors and self-efficacy among Chinese HF patients.

METHODS

A cross-sectional study with a convenience sample was conducted. All participants completed the questionnaires of the self-care of HF index (V6) and type D personality scale. Demographic and clinical variables were obtained from medical records and patient interviews. The methods used for data analysis included descriptive analysis, independent-sample t-test, χ (2) test, and multiple linear regression.

RESULTS

A total of 127 HF patients were included and 61.4% of them were male. The average age for this study sample was 64.9 ± 12.34 years. The majority of the participants were in a New York Heart Association class III or IV (87%), and the average length of living with HF was 38.24 ± 41.1 months. A total of 33.1% of the participants were identified as having type D personality. No significant differences were determined in the demographic and clinical variables between type D and non-type D patients, except for the mean age and the length of living with HF. Type D patients were younger and had a shorter time of living with HF than their non-type D counterparts. Multiple regression demonstrated significant associations between type D personality and self-care maintenance and self-efficacy after adjusting the demographic and clinical factors. However, type D personality was not significantly associated with self-care management behaviors.

CONCLUSIONS

Type D personality was negatively related to self-care maintenance and self-efficacy in Chinese HF patients. Future study is warranted to develop a tailored intervention to improve engagement in self-care behaviors in HF patients with type D personality.

Type D Personality in Gastric Cancer Survivors: Association With Poor Quality of Life, Overall Survival, and Mental Health

CONTEXT

The associations between Type D personality and poor quality of life, overall survival, and mental health in gastric cancer survivors.

OBJECTIVES

The aim of this research was to explore quality of life (QoL), mental health status, Type D personality, symptom duration, and emergency admissions of Chinese gastric cancer patients, as well as the relationship between these factors.

METHODS

Eight hundred thirty eligible Chinese patients newly diagnosed with gastric cancer between July 2009 and July 2011 were enrolled in this prospective study. Type D personality was measured with the 14-item Type D Personality Scale (DS14). Mental health status was measured with the Hospital Anxiety and Depression Scale. The QoL outcomes were assessed longitudinally using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 and Quality of Life Questionnaire-STO22 at baseline and six months after diagnosis.

RESULTS

The proportion of patients with symptom duration of more than one month and who were diagnosed after emergency admissions in the Type D group was significantly higher than that in the non-Type D personality group. At both of the time points, Type D patients reported statistically significant lower scores on role, emotional, cognitive, and social functioning (all Ps < 0.001) functional scales, global health status/QoL scales (P < 0.001), and worse symptom scores compared to patients without a Type D personality. During the six-month time frame, a higher percentage of patients in the Type D group demonstrated a considerable QoL deterioration. Clinically elevated levels of anxiety and depression were more prevalent in Type D than in non-Type D survivors (both Ps < 0.001). There was a statistically significant difference in three-year overall survival between the patients in the Type D group and the non-Type D personality group.

CONCLUSION

Type D personality is associated with poor QoL, three-year overall survival and mental health status among survivors of gastric cancer, even after adjustment of confounding background variables. The Type D personality group experienced increased levels of pain and fatigue compared to non-Type D patients. Type D personality might be a general vulnerability factor to screen for subgroups at risk of longer symptom duration and emergency admissions in clinical practice.

Type D Personality and Coronary Plaque Vulnerability in Patients With Coronary Artery Disease: An Optical Coherence Tomography Study

OBJECTIVE

To investigate the association between Type D personality and higher incidence of major adverse cardiac events, we used in vivo optical coherence tomography (OCT) to evaluate the association between Type D with coronary plaque characteristics.

METHODS

A total of 109 patients who had culprit coronary plaque (s) were included in the study. The Type D construct was analyzed using both the categorized and the continuous approaches. Plaque vulnerability of culprit lesions was measured by OCT.

RESULTS

After adjusting for demographic and clinical factors, multivariate analysis demonstrated that Type D was associated with lipid plaque (odds ratio [OR] = 4.87, 95% confidence interval [CI] = 1.41-11.14, p = .025), thin cap fibroatheroma (OR = 3.84, 95% CI = 1.36-10.85, p = .011), and fibrous cap thickness (β = -1.43, standard error = 0.04, p = .001) analyzed by categorical approach. When analyzing Type D as continuous variable, the negative affectivity component was significantly related to plaque vulnerability, including lipid plaque (OR = 3.43, 95% CI = 1.23-9.52, p = .018), thin cap fibroatheroma (OR = 2.20, 95% CI = 1.10-4.40, p = .026), and fibrous cap thickness (β = -0.05, standard error = 0.02, p = .030), whereas no associations between the negative affectivity by social inhibition interaction term with OCT indices were found.

CONCLUSIONS

The results suggest that plaque characteristics in Type D have more features of plaque vulnerability. The negative affectivity component seems to drive the associations between Type D and vulnerable plaques. These findings provide new insights into the mechanism involved in the association between Type D and major adverse cardiac event.

Type D personality is related to severity of acute coronary syndrome in patients with recurrent cardiovascular disease

OBJECTIVES

To investigate the relationship between Type D (distressed) personality and cardiac biomarkers of disease severity in patients with acute coronary syndrome. To identify potential mechanisms behind the effect of Type D personality on cardiovascular disease (CVD).

DESIGN

Cross-sectional.

METHODS

Patients (N = 215) with acute coronary syndrome completed a survey including a measure of Type D personality. Blood samples including a lipid profile and cardiac enzymes were taken within 3 days after the cardiovascular event. Data were analysed using simple correlations, multiple regressions, and mediation analyses.

RESULTS

Type D personality was more predictive of severity of the acute coronary syndrome among patients with previous CVD compared to patients without previous CVD. Among patients with previous CVD, Type D personality was associated with the presence of ST elevation (R(2)  =.07) and more damage to the myocardium as indicated by higher troponin-I (R(2)  = .05) and myoglobin (R(2)  = .07) levels. These effects were independent from demographics, CV risk factors, and depression. Lower HDL cholesterol levels mediated the relationship between Type D personality and disease severity (Κ(2)  = .12 [95% CI 0.02, 0.28]) for myoglobin and Κ(2)  = .08 [95% CI 0.01, 0.21] for troponin-I).

CONCLUSION

Type D personality was related to a worse lipid profile and more severe acute coronary syndrome in patients with previous history of CVD. Given the strong relationship between disease severity and subsequent mortality, these results suggest that severity of the myocardial infarction may be a potential mechanism explaining increased mortality in Type D patients with recurrent CVD. Statement of contribution What is already known on this subject? Type D personality has been related to worse outcomes in cardiac patients. However, recent studies show mixed results, suggesting the need to clarify potential mechanisms. What does this study add? Type D personality is related to severity of acute coronary syndrome in patients with previous history of cardiovascular disease. This effect is partially accounted for by lower HDL levels in Type D patients. Disease severity is a potential mechanism by which Type D personality may affect cardiovascular health of patients with recurrent CVD.

Psychological Determinants of Heart Failure Self-Care: Systematic Review and Meta-Analysis

OBJECTIVE

Psychological distress has been associated with poor outcomes in patients with chronic heart failure (HF), which is assumed to be partly due to poor HF self-care behavior. This systematic review and meta-analysis describes the current evidence concerning psychological determinants of self-care in patients with chronic HF.

METHODS

Eligible studies were systematically identified by searching electronic databases PubMed, PsycINFO, and the Conference Proceedings Citation Index (Web of Science) for relevant literature (1980-October 17, 2014). Study quality was assessed according to the level of risk of bias. Quantitative data were pooled using random-effects models.

RESULTS

Sixty-five studies were identified for inclusion that varied considerably with respect to sample and study characteristics. Risk of bias was high in the reviewed studies and most problematic with regard to selection bias (67%). Depression (r = -0.19, p < .001), self-efficacy (r = 0.37, p < .001), and mental well-being (r = 0.14, p = .030) were significantly associated with self-reported self-care. Anxiety was not significantly associated with either self-reported (r = -0.18, p = .24) or objective self-care (r = -0.04, p = .79), neither was depression associated with objectively measured medication adherence (r = -0.05, p = .44).

CONCLUSIONS

Psychological factors (depression, self-efficacy, and mental well-being) were associated with specific self-care facets in patients with chronic HF. These associations were predominantly observed with self-reported indices of self-care and not objective indices. Methodological heterogeneity and limitations preclude definite conclusions about the association between psychological factors and self-care and should be addressed in future research.

Type D Personality Predicts Poor Medication Adherence in Chinese Patients with Type 2 Diabetes Mellitus: A Six-Month Follow-Up Study

Background

Type D personality and medication nonadherence have been shown to be associated with poor health outcomes. Type D personality is associated with poor medication adherence in patients with coronary artery disease, myocardial infarction, and heart failure. However, the relationship between type D personality and medication adherence in patients with Type 2 Diabetes Mellitus (T2DM) remains unknown. This study aims to examine whether type D personality was associated with medication adherence in patients with T2DM.

Design and Settings

A follow-up study was conducted in general hospital of the People's Liberation Army in Beijing.

Methods

412 T2DM patients (205 females), who were recruited by circular systematic random sampling, provided demographic and baseline data about medical information and completed measures of Type D personality. Then, 330 patients went on to complete a self-report measure of medication adherence at the sixth month after baseline data collection. Chi-square test, t tests, and hierarchical multiple regression analyses were conducted, as needed.

Results

Patients with type D personality were significantly more likely to have poor medication adherence (p<0.001). Type D personality predicts poor medication adherence before and after controlling for covariates when it was analyzed as a categorical variable. However, the dimensional construct of type D personality was not associated with medication adherence when analyzed as a continuous variable.

Conclusion

Although, as a dimensional construct, type D personality may not reflect the components of the personality associated with poor medication adherence in patients with T2DM, screening for type D personality may help to identify those who are at higher risk of poor medication adherence. Interventions, aiming to improve medication adherence, should be launched for these high-risk patients.

Self-Care and All-Cause Mortality in Patients With Chronic Heart Failure

OBJECTIVES

This study examined the association of self-care with all-cause mortality in a cohort of patients with chronic heart failure (HF).

BACKGROUND

Although self-care is crucial to maintain health in patients with chronic HF, studies examining an association with clinical outcomes are scarce.

METHODS

Consecutive patients with chronic HF (n = 559, mean age 66.3 ± 9.5 years, 78% men) completed the 9-item European Heart Failure Self-care Behaviour scale. Our endpoint was all-cause mortality. Associations between self-care and all-cause mortality were assessed with Kaplan-Meier analyses and multivariable Cox regression accounting for standard sociodemographic and clinical covariates, psychological distress, and self-rated health.

RESULTS

After a median follow-up of 5.5 ± 2.4 years (range 16 weeks to 9.9 years), 221 deaths (40%) from any cause were recorded. There was no evidence of a mortality benefit in patients high over those low in global self-care (p = 0.71). In post hoc analyses, low self-reported sodium intake was associated with increased mortality (adjusted hazard ratio: 1.47; 95% confidence interval: 1.10 to 1.96; p = 0.01). Other significant predictors of mortality were: male sex, lack of a partner, New York Heart Association functional class III to IV, and increasing comorbid conditions.

CONCLUSIONS

Global self-care was not associated with long-term mortality whereas low self-reported sodium intake independently predicted increased all-cause mortality beyond parameters of disease severity. Replication of findings is needed as well as studies examining the correspondence of subjectively and objectively measured sodium intake and its effects on long-term prognosis in patients with chronic HF.

Type D personality is associated with delaying patients to medical assessment and poor quality of life among rectal cancer survivors

OBJECTIVE

The aim of this research was to explore quality of life (QoL), mental health status, type D personality, symptom duration, and emergency admissions of Chinese rectal cancer patients as well as the relationship between these factors.

METHODS

Type D personality was measured with the 14-item Type D Personality Scale (DS14). Mental health status was measured with the Hospital Anxiety and Depression Scale (HADS). The QoL outcomes were assessed longitudinally using the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-CR38 questionnaires at the baseline and 6 months after diagnosis.

RESULTS

Of the 852 survivors who responded (94 %), 187 (22 %) had a type D personality. The proportion of patients with duration of symptoms >1 month and being diagnosed after emergency admissions in type D group is significantly higher than that in non-type D group. At both of the time points, type D patients reported statistically significant lower scores on most of the functional scales, global health status/QoL scales, and worse symptom scores compared to patients without a type D personality. At the 6-month time point, a higher percentage of patients in the type D group demonstrated QoL deterioration. Clinically elevated levels of anxiety and depression were more prevalent in type D than in non-type D survivors.

CONCLUSIONS

Type D personality was associated with poor QoL and mental health status among survivors of rectal cancer, even after adjustment for confounding background variables. Type D personality might be a general vulnerability factor to screen for subgroups at risk for longer symptom duration and emergency admissions in clinical practice.

Type D personality predicts poor medication adherence in patients with heart failure in the USA

BACKGROUND

Type D (distressed) personality and medication nonadherence have been associated with poor health outcomes. Type D personality is associated with poor medication adherence in patients with coronary artery disease. However, the relationship between type D personality and medication adherence in patients with heart failure (HF) remains unknown.

PURPOSE

Therefore, the goal of this study was to examine the association between type D personality and medication adherence in patients with HF.

METHOD

This was a sub-analysis of baseline data from a randomized controlled trial with 84 patients with HF in the USA. Demographic, clinical, and psychological data were collected at baseline by interview, questionnaires, and medical record review. Type D personality was assessed using the Type D Personality Scale (DS14). Medication adherence was measured using both objective (Medication Event Monitoring System, MEMS) and self-reported (Morisky Medication Adherence Scale, MMAS-4) measures. Patients started medication adherence monitoring with the MEMS bottle at baseline and is used continuously for a month. Multiple regressions were used to explore the relationships between type D personality and medication adherence while adjusting for demographic, clinical, and psychological factors.

RESULTS

Patients with type D personality were more likely to have poor medication adherence. Type D personality was associated with medication adherence before and after adjusting for covariates when it was analyzed as a categorical variable. However, type D personality was not associated with medication adherence when analyzed as a dimensional construct. Negative affectivity, a component of type D personality, was associated with medication adherence.

CONCLUSION

As a dimensional construct, type D personality may not reflect the components of the personality associated with poor outcomes. Negative affectivity was associated with medication adherence in patients with HF. Interventions aiming to improving/enhancing medication adherence need to take into account patients with the negative affectivity component of type D personality who are at higher risk for poor medication adherence, which may lead to adverse health outcomes.

Type D personality, self-efficacy, and medication adherence in patients with heart failure-A mediation analysis

BACKGROUND

Type D personality is associated with medication non-adherence. Both Type D personality and non-adherence are predictors of poor outcomes. Self-efficacy, which is modifiable, is also associated with medication adherence.

OBJECTIVES

To determine the relationships among Type D personality, self-efficacy, and medication adherence in 84 heart failure patients.

METHODS

Self-efficacy, Type D personality, medication adherence, demographic and clinical data were collected. Hierarchical linear regression was used.

RESULTS

Type D patients were more likely to have lower self-efficacy (p = .023) and medication non-adherence (p = .027) than non-Type D patients. Low self-efficacy was associated with medication non-adherence (p < .001). Type D personality didn't predict medication adherence after entering self-efficacy in the model (p = .422), demonstrating mediation.

CONCLUSIONS

Self-efficacy mediates the relationship between Type D personality and medication adherence. Developing and applying interventions to enhance self-efficacy may help to sever the link between Type D personality and poor outcomes.

Type D personality, suboptimal health behaviors and emotional distress in adults with diabetes: results from Diabetes MILES-The Netherlands

AIMS

Type D personality - defined as high negative affectivity (NA) and high social inhibition (SI) - has been associated with adverse cardiovascular prognosis. We explored the differential associations of Type D personality and its constituent components with health behaviors, emotional distress and standard biomedical risk factors as potential risk mechanisms in adults with diabetes.

METHODS

3314 Dutch adults with self-reported type 1 or 2 diabetes completed an online survey, including the DS14 Type D Scale. AN(C)OVAs and X(2) tests were used to compare participants scoring (i) low on NA and SI; (ii) high on SI only; (iii) high on NA only; (iv) high on NA and SI (Type D).

RESULTS

Participants with Type D personality (29%) were less likely to follow a healthy diet or to consult healthcare professionals in case of problems with diabetes management than those scoring high on neither or only one component. They also reported more barriers surrounding medication use, diabetes-specific social anxiety, loneliness and symptoms of depression and anxiety. There were no differences in standard biomedical risk factors (body mass index, blood pressure, cholesterol, HbA1c). After adjustment for demographics, clinical characteristics, NA, and SI in multivariable logistic regression analyses, Type D personality was independently associated with 2 to 3-fold increased odds of suboptimal health behaviors and over 15-fold increased odds of general emotional distress.

CONCLUSIONS

Type D personality was not related to standard biomedical risk factors, but was associated with unhealthy behaviors and negative emotions that are likely to have adverse impact on adults with diabetes.

The impact of type D personality on health-related quality of life in patients with symptomatic haemorrhoids

Introduction

Haemorrhoids are one of the most common reasons that patients seek consultation from a colon and rectal surgeon. Health-related quality of life (HrQoL) is a significant factor in describing the burden of illness and the impact of treatment in patients with gastrointestinal disease. Type D (distressed) personality is defined as the co-occurrence of negative affect and social inhibition.

Aim

To assess the prevalence of type D personality in patients with haemorrhoids and to investigate whether the presence of a type D personality would affect HrQoL in patients with haemorrhoids.

Material and methods

One hundred and six outpatients with symptomatic haemorrhoids with no psychiatric comorbidity were consecutively enrolled, along with 96 healthy controls. The Type D Scale (DS14) and the General Health Survey Short Form-36 (SF-36) were used in the collection of data.

Results

Of 106 patients evaluated, 29.2% met criteria for type D personality. Patients with haemorrhoids scored lower on bodily pain and vitality dimensions of SF-36 than did healthy subjects (p < 0.001). Patients with a type D personality were found to score lower on bodily pain domain of HrQoL than patients without a type D personality. Linear regression analysis revealed a significant independent association of type D personality with bodily pain dimension of the SF-36 in patients with symptomatic haemorrhoids (r = –0.315, p < 0.01).

Conclusions

Type D personality was associated with increased perceived bodily pain in patients with haemorrhoids. Consideration of type D personality construct personality traits could improve risk stratification in research and clinical practice in this patient group.

Positive affect, anhedonia, and compliance with self-care in patients with chronic heart failure

OBJECTIVE

Optimal self-care is crucial in patients with chronic heart failure (HF). While the focus of research has been on negative mood states, adequate psychological resources may be required to successfully engage in HF self-care. Therefore, the longitudinal associations of multiple positive affect measures in explaining HF self-care including consulting behavior were examined while adjusting for depressive symptoms and potential covariates (e.g., disease severity).

METHODS

In this prospective cohort study, 238 patients (mean age: 66.9 ± 8.6 years, 78% men), with chronic HF completed questionnaires at baseline and 1-year follow-up. Positive affect was assessed with the Positive and Negative Affect Schedule (PANAS) and the Global Mood Scale (GMS). Anhedonia, i.e. diminished interest or pleasure, was assessed with a subscale of the Hospital Anxiety and Depression Scale (HADS). The 9-item European Heart Failure Self-care Behaviour scale was completed to assess HF self-care including consultation behavior.

RESULTS

Linear mixed modeling results showed that anhedonia was most strongly associated with both poor self-care (estimate=-.72, P<.001) and consulting behavior (estimate=-.44, P<.001) over time, after adjustment for covariates and depressive symptoms. GMS positive affect was related to better HF self-care adjusting for standard depressive symptoms but not when adjusting for anhedonia. PANAS positive affect was not independently related to self-care.

CONCLUSION

Anhedonia was associated with worse compliance with self-care among chronic HF patients over time, irrespective of disease severity and depression. Associations between positive affect and self-care were dependent on the measures used in multivariable analyses.

Health-related quality of life in patients with anal fissure: effect of type D personality

INTRODUCTION

Health-related quality of life (HRQL) is a significant factor in describing the burden of illness and the impact of treatment in patients with gastrointestinal disease. Type D (distressed) personality is defined as the co-occurrence of negative affect and social inhibition.

AIM

To assess the prevalence of type D personality in patients with anal fissure and to investigate whether the presence of a type D personality would affect HRQL in patients with anal fissure.

MATERIAL AND METHODS

One hundred outpatients with anal fissure with no psychiatric comorbidity were consecutively enrolled, along with 100 healthy controls. Type D Scale (DS14) and General Health Survey Short Form-36 (SF-36) were used in the collection of data.

RESULTS

Patients with anal fissure scored lower on physical roles and bodily pain dimensions of SF-36 than healthy subjects (p < 0.05). Thirty-three patients with anal fissure (33%) and 16 controls (16%) had scored above the cut-off score of the DS14 (p < 0.05). Patients with a type D personality were found to score lower on bodily pain and social roles domains of HRQL than patients without a type D personality.

CONCLUSIONS

Type D personality was associated with increased perceived bodily pain and social roles in patients with anal fissure. Type D personality construct may be an important consideration when assessing HRQL outcomes. A multidimensional approach may be valuable in the assessment of patients presenting with anal fissure, because a subgroup with type-D personality might benefit from psychological therapies.

Depression in parents of children with leukemia in southern China accompanied by the prevalence of type D personality

PURPOSE

The aims of this study were to assess depression and type D personality in parents of children with leukemia in southern China and to investigate the associations between parents' depression and type D personality, social support, coping style, and demographic characteristics.

METHODS

Parents (n=231) of children with leukemia (study group) and parents (n=261) of children with acute respiratory/digestive infections (control group) were recruited from five hospitals in southern China. Children's clinical characteristics and parents' demographic characteristics, depression, type D personality, coping styles, and social support were collected with self-report questionnaires.

RESULTS

Parents of children with leukemia, especially mothers, reported higher levels of depression accompanied by a higher prevalence of type D personality, more negative coping styles, and less subjective social support, but received more objective social support than controls (P<0.05). The depression in parents in the study group was positively correlated with type D personality and negative coping style, but negatively correlated with social support and positive coping styles (P<0.05). Multivariate logistic regression analyses showed that type D personality (OR=5.64, P<0.001), lower social support (OR=2.38, P=0.020), and less positive coping (OR=3.32, P=0.003) were independently associated with depression in parents of children with leukemia. As for demographic characteristics, female, lower education level, unemployed, and paying medical expenses at one's own expenses were independent predictors of depression in parents of children with leukemia.

CONCLUSION

Depression and type D personality were remarkably prevalent in parents of children with leukemia in southern China. Type D personality and multiple social factors were associated with depression in parents of children with leukemia.

Effect of Type D personality on medication adherence in early adolescents with asthma

OBJECTIVE

Medication adherence for daily preventive asthma medication is especially low during adolescence. In the present study, we aimed to test whether Type D personality (both as a category and with its constituent components (negative affectivity: NA and social inhibition: SI) separately and in interaction) predicts medication adherence of early adolescents with asthma.

METHODS

In a prospective study, 188 early adolescents with asthma who were prescribed daily preventive asthma medication completed questionnaires on Type D personality, medication adherence, socio-demographic and clinical information, and depressive symptoms in the Spring/Summer of 2011 (T1) and again 12months later (T2). Multiple regression analyses, controlling for demographic and clinical information and for depressive symptoms, were conducted to test whether Type D personality (either as a categorical or dimensional construct) predicted changes in medication adherence over time.

RESULTS

Adherence was significantly lower at T2 than at T1 and this decrease was predicted by the categorical construct of Type D personality. Analyses of the two separate dimensions NA and SI and their interaction showed that higher scores on NA at T1 predicted more decrease in adherence over time. Neither SI nor the interaction between NA and SI predicted changes in adherence.

CONCLUSION

This is the first study to test the relationship between Type D personality and medication adherence in adolescents. Although categorical Type D personality predicts mediation adherence of adolescent with asthma over time, dimensional analyses suggest that this is due to negative affectivity only, and not to the combination of negative affectivity and social inhibition.

Predictive value of social inhibition and negative affectivity for cardiovascular events and mortality in patients with coronary artery disease: the type D personality construct

OBJECTIVE

Methodological considerations and selected null findings indicate the need to reexamine the Type D construct. We investigated whether associations with cardiac events in patients with coronary artery disease (CAD) involve the specific combination of negative affectivity (NA) and social inhibition (SI), or rather the main effect of either trait alone.

METHODS

In this 5-year follow-up of 541 patients with CAD, the Type D construct (14-item Type D Scale) was tested by examining a) the interaction of continuous NA and SI z scores and b) a four-group classification defined by low/high trait scores. End points were major adverse cardiac events (MACEs; death, myocardial infarction [MI], coronary revascularization) and cardiac death/MI.

RESULTS

At follow-up, 113 patients had a MACE, including 47 patients with cardiac death/MI. After adjustment for disease severity, age, sex, and main trait effects, the interaction of NA and SI z scores was associated with MACE (odds ratio [OR] = 1.36, 95% confidence interval [CI] = 1.11-1.67). This continuous measure of Type D was also associated with cardiac death/MI (OR = 1.48, 95% CI = 1.11-1.96) and remained an independent predictor of events after adjustment for depressive symptoms. Using a cutoff of 10 on both NA and SI scales, Type D was associated with an adjusted OR of 1.74 (95% CI = 1.11-2.73) for MACE and an OR of 2.35 (95% CI = 1.26-4.38) for death/MI but was unrelated to noncardiac death. Patients with high NA or SI alone were not at increased risk.

CONCLUSIONS

Continuous (NA × SI interaction) and dichotomized measures of Type D were associated with cardiovascular events in patients with CAD. Research is needed to explore moderating factors that may alter this association.

Type D personality is associated with psychological distress and poor self-rated health among the elderly: a population-based study in Japan

We investigated the association between Type D personality, psychological distress, and self-ratings of poor health in elderly Japanese people. In August 2010, questionnaires were sent to all residents aged ≥65 in three municipalities (n = 21232) in Okayama Prefecture, Japan, and. 13929 questionnaires were returned (response rate: 65.6%). To assess mental and physical health outcomes, we used the Kessler Psychological Distress Scale and a single item question regarding perceived general health. We analyzed 9759 questionnaires to determine odds ratios (ORs) and 95% confidence intervals (CIs) for several health outcomes, adjusting for sex, age, smoking status, frequency of alcohol consumption, overweight status, educational attainment, socioeconomic status, and number of cohabiters. The multiple imputation method was employed for missing data regarding Type D personality. The prevalence of Type D personality in our sample was 46.2%. After adjusting for covariates, we found that participants with Type D personality were at 4–5 times the risk of psychological distress, and twice the risk of poor self-rated health. This association was stronger in participants aged 65–74 years (psychological distress; OR: 5.80, 95% CI: 4.96–6.78, poor self-rated health; OR: 2.84, 95% CI: 2.38–3.38) than in those aged over 75 years (psychological distress; OR: 4.54, 95% CI: 3.96–5.19, poor self-rated health; OR: 2.05, 95% CI: 1.79–2.34). Type D personality is associated with adverse health status among Japanese elderly people in terms of mental and physical risk; therefore, further research into the implications of this personality type is warranted.

The distressed (Type D) personality mediates the relationship between remembered parenting and psychological distress in cardiac patients

OBJECTIVE

Both the distressed (Type D) personality (i.e. the combination of negative affectivity and social inhibition traits) and dysfunctional parenting styles are associated with anxiety and depression. As parenting styles have been related to personality development, dysfunctional parenting styles may also be associated with Type D personality. We examined whether remembered parenting was associated with anxiety and depression in cardiac patients and whether Type D personality mediated this relationship.

METHODS

Our sample comprised 435 patients treated with percutaneous coronary intervention (PCI) and 123 patients with congestive heart failure (CHF). Patients completed the Hospital Anxiety and Depression Scale, Type D Scale (DS14), and Remembered Relationship with Parents (RRP(10)) scale.

RESULTS

Remembered parenting was significantly associated with higher anxiety and depression levels and Type D personality. In multivariable linear regression analyses, Type D personality accounted for 25-29% of the variance in anxiety and 23-46% of the variance in depression, while remembered parenting was no longer significantly associated with these domains. Sobel tests and bootstrapping indicated that Type D personality mediated the relationship between remembered parenting and anxiety and depression.

CONCLUSION

Type D personality mediated the relationship between remembered parenting and anxiety and depression in both PCI and CHF patients.

Type D personality is associated with sleep problems in adolescents. Results from a population-based cohort study of Swedish adolescents

OBJECTIVE

Sleep problems are associated with an increased risk of psychiatric and somatic diseases. Type D personality, or the distressed personality, refers to the joint tendency to experience negative emotions and to inhibit self-expression in social interaction. Type D personality is associated with an increased number of health complaints including cardiovascular diseases. The present study investigated whether type D personality was associated with sleep problems among adolescents.

METHODS

The study was part of the Survey of Adolescent Life in Västmanland 2008 (SALVe 2008). A total of 5012 adolescents (age 15-18 years old) completed a questionnaire including the type D measurement DS14 and questions on sleep disturbances, sleep hours during school nights, and sleep hours during weekend nights.

RESULTS

Adolescents with a type D personality had an approximately four times increased risk of having sleep disturbances. Moreover, type D personality was associated with sleeping fewer hours.

CONCLUSION

As adolescence represents a formative period for development it is critical to identify sleep disorders early. The presence of type D personality associated with poor sleep demands attention because sleep problems may be an early stage in the development of later diseases.

Type D personality is a risk factor for psychosomatic symptoms and musculoskeletal pain among adolescents: a cross-sectional study of a large population-based cohort of Swedish adolescents

BACKGROUND

Type D personality, or the "distressed personality", is a psychosocial factor associated with negative health outcomes, although its impact in younger populations is unclear. The purpose of this study was to investigate the prevalence of Type D personality and the associations between Type D personality and psychosomatic symptoms and musculoskeletal pain among adolescences.

METHODS

A population-based, self-reported cross-sectional study conducted in Västmanland, Sweden with a cohort of 5012 students in the age between 15-18 years old. The participants completed the anonymous questionnaire Survey of Adolescent Life in Västmanland 2008 during class hour. Psychosomatic symptoms and musculoskeletal pain were measured through index measuring the presence of symptoms and how common they were. DS14 and its two component subscales of negative affectivity (NA) and social inhibition (SI) were measured as well.

RESULTS

There was a difference depending on sex, where 10.4% among boys and 14.6% among girls (p = < 0.001) were defined as Type D personality. Boys and girls with a Type D personality had an approximately 2-fold increased odds of musculoskeletal pain and a 5-fold increased odds of psychosomatic symptoms. The subscale NA explained most of the relationship between Type D personality and psychosomatic symptoms and musculoskeletal pain. No interaction effect of NA and SI was found.

CONCLUSIONS

There was a strong association between Type D personality and both psychosomatic symptoms and musculoskeletal pain where adolescent with a type D personality reported more symptoms. The present study contributes to the mapping of the influence of Type D on psychosomatic symptoms and musculoskeletal pain among adolescents.

Preliminary evidence for the construct and concurrent validity of the DS14 in Hebrew

BACKGROUND

Type D personality is a risk indicator in cardiac patients. While both the validity and reliability of the Type D scale (DS14) have been confirmed in Western Europe, less attention has been paid to the subject in other nations.

PURPOSE

The purpose of this study was to examine the validity of the Hebrew version of the DS14 among a sample of cardiac patients in Israel.

METHOD

Male patients (N = 94) hospitalized for a first acute coronary syndrome (ACS) completed the DS14 1 month after their ACS. The Brief Symptoms Inventory (BSI) scales for depression and anxiety and the Buss-Durkee Hostility Inventory-Dutch for measuring covert and overt aggressions were administered during the initial hospitalization (baseline). The BSI was administered again at the 6-month follow-up. At follow-up, patients were also asked about their participation in a formal cardiac rehabilitation program.

RESULTS

The two-factor structure of the DS14 was confirmed and the DS14 subscales were internally consistent (Cronbach's α = 0.79/0.80). Type D cardiac patients had a significantly higher mean score on anxiety, depression, and covert aggression at baseline compared to non-Type D patients. At the 6-month follow-up, Type D was associated with more anxiety, more depression, and less attendance at a formal cardiac rehabilitation program. The prevalence of Type D in the current sample (5.3%) was found to be significantly lower than elsewhere in Europe.

CONCLUSION

Preliminary evidence suggests that it is possible to use the Hebrew version of the DS14 among Hebrew-speaking cardiac patients in future studies. However, the prevalence of the Type D personality in Israel should be further assessed.
