Inadequate consultation behavior modulates the relationship between Type D personality and impaired health status in chronic heart failure

Determinants of information needs in patients with coronary artery disease receiving cardiac rehabilitation: a prospective observational study

OBJECTIVES

Knowledge on information needs in cardiac rehabilitation (CR) patients is scarce. This study investigates determinants of information needs in patients with coronary artery disease (CAD).

DESIGN

Prospective observational study.

PARTICIPANTS

A total of 259 patients participated.

SETTING

CR centre serving a general hospital in The Netherlands.

METHODS

Patients with a coronary event and/or revascularisation referred for CR completed questionnaires assessing their level of information needs with respect to nutrition, physical activity, smoking, medication use and psychological well-being, and potential determinants of information needs (sociodemographic characteristics, health literacy, illness perceptions, anxiety, depression, Type D personality and quality of life).

RESULTS

The majority (63%) of patients indicated a need for information on at least one of the four topics (nutrition, physical activity, medication use, psychological well-being), with considerable inter-individual variation. Female sex, being employed, higher socioeconomic status, higher levels of anxiety and higher illness perception were associated with higher information needs on specific topics.

CONCLUSIONS

The majority of CR patients with CAD have a need for information, with considerable inter-individual variability. Several demographic, socioeconomic and psychosocial characteristics were related to their preference for information topics. These results underline the need for personalised information strategies in patients undergoing CR.

Four years stability of type D personality in patients with moderate to severe psoriasis and its implications for psychological impairment

Background

Psoriasis is a systemic auto-inflammatory disease that is related to an increased risk of organic and psychological comorbidities. Type D is a stable personality trait in healthy subjects but there is no data regarding its stability in patients with moderate-severe psoriasis.

Objectives

To assess the stability of type D personality in patients with moderate to severe psoriasis as well as assessing the influence of type D personality on anxiety and depression.

Methods

Prospective cohort study. Forty psoriasis patients with type D personality and sixty-six patients with psoriasis without type D personality were included in the study. Participants completed the DS14 test and HADS at baseline and four years later.

Results

At baseline, the prevalence of type D personality was 37.7% and at week 208 it was 27.3%. The stability of type D personality was higher in patients with an incomplete education level and in those who were separated/divorced or windowed. During follow-up, 15% of patients developed type D personality. Male sex, having topical treatment, the presence of previous depression, anxiety, and high levels of negative affectivity at baseline increase the risk of developing type D personality.

Study limitations

Sample size, psoriasis severity restricted to moderate and severe and all patients being under treatment for psoriasis.

Conclusions

The presence of type D personality varies over time in psoriasis patients. Therefore, type D personality is possibly more a state than a trait phenomenon, modified by environmental factors. Type D personality is associated with a higher risk of anxiety.

Situation selection and modification in social inhibition: a person-centered approach

OBJECTIVES

The current study aimed to identify patterns of situation selection and modification behaviors using a person-centered approach, and to examine to what extent the trait social inhibition (SI) is associated with these patterns of situation-targeted emotion regulation.

METHODS

The sample comprised 504 participants (M_age= 21.5, SD = 8.2; 82% women), who completed questionnaires on situation selection and modification behaviors, and the social inhibition questionnaire (SIQ15). A three-step latent profile analysis (LPA) was performed to (A) identify existing latent profiles of situation avoidance and approach and situation modification behaviors, and (B) to examine the association of SI and facets with the latent class posteriors.

RESULTS

LPA revealed the presence of four profiles that differed in how situation selection and modification were applied. SI, behavioral inhibition, and social withdrawal were significantly associated with a higher odds of belonging to the profile characterized by avoidance selection and modification. Interpersonal sensitivity was associated with using more conversational modification behaviors, which may illustrate that interpersonal sensitive individuals are motivated to approach, but use avoidance behaviors to prevent confrontation.

CONCLUSIONS

SI individuals particularly rely on avoidance selection and modification behaviors, which may be considered maladaptive emotion regulation.

Type D personality has been previously shown to increase the risk for mortality in patients with acquired heart disease.

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.

Factors associated with self-care behaviours among Koreans with heart failure

BACKGROUND

Self-care behaviours are important to improve health outcomes in patients with heart failure. However, little is known about the factors related to the subdimensions of self-care behaviours in these patients.

AIMS

To identify the factors associated with the subdimensions of self-care behaviours among South Korean patients with heart failure.

METHODS

The participants in this cross-sectional descriptive study conducted between October 2016 and January 2017 were 178 patients with heart failure. Self-care behaviours were measured using the EHFScB-9, which has three subdimensions: autonomy-based adherence; provider-directed adherence; and consulting behaviours. Demographic characteristics, experience of heart failure education, physical function, patient health questionnaire-9, Pittsburgh sleep quality index and self-care confidence were also measured. Descriptive statistics and multiple linear regression analysis were conducted.

RESULTS

The mean age was 62 ± 12 years, and 37% were women. Younger age (P=0.023), no experience of heart failure education (P=0.039), poor physical function (P=0.003), poor sleep quality (P=0.037) and lower self-care confidence (P=0.001) were significantly associated with poor autonomy-based adherence. Being employed (P=0.042), poor sleep quality (P=0.042) and lower levels of self-care confidence (P=0.001) were associated with poor provider-directed adherence. Younger age (P=0.001) and lower self-care confidence (P=0.001) were associated with lower engagement in consulting behaviours.

CONCLUSION

The three subdimensions of self-care behaviours were associated with different psychosocial factors, necessitating the development of tailored interventions and educational materials based on unique self-care behaviour patterns in patients with heart failure.

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.

Psychosocial markers of pre-hospital decision delay and psychological distress in acute coronary syndrome patients

Objectives Both pre-hospital decision delay - the time patients wait before seeking medical attention after symptoms have started - and high psychological distress after the cardiac episode predict poor prognosis of patients with acute coronary syndromes (ACS). We aimed to identify psychosocial markers of these prognostic factors. Design A cross-sectional study of 102 consecutive, clinically stable ACS survivors. Methods Participants completed a questionnaire measuring pre-hospital decision delay, psychological distress, and several known psychosocial factors related to cardiovascular health: type D personality, resilience, social support, and concerns during the cardiac event. Multiple linear regression and mediation analyses were conducted. Results Type D personality and fewer concerns about the serious consequences of delaying help-seeking were related to more psychological distress post-ACS, and these relationships were mediated by longer pre-hospital decision delay. In contrast, resilience was related to lower psychological distress. Social support and social concerns about help-seeking were not related to the outcome variables. Conclusions Type D personality may be a risk factor for more delayed help-seeking for an ACS and higher psychological distress after the cardiac event. Resilience, in contrast, emerged as a potential protective factor of patients' mental health after the cardiac event. Pre-hospital decision delay was related to thinking about serious consequences (e.g., complications, protecting one's family) but not about social concerns (e.g., wasting other people's time) during the cardiac episode. Statement of Contribution What is already known on this subject? Longer pre-hospital decision delay, that is waiting longer to seek medical attention after symptoms have started, predicts poor prognosis of acute coronary syndrome patients. High psychological distress post-ACS, such as the development of anxiety and/or depression, also predicts poor prognosis of these patients. What does this study adds? This study identifies several psychosocial markers of longer prehospital decision delay and high psychological distress post-ACS. Prehospital decision delay was related to thinking about serious consequences (e.g., complications, protecting one's family) but not about social concerns (e.g., wasting other people's time) during the cardiac episode. Type D personality and fewer concerns about the serious consequences of delaying help-seeking were related to more psychological distress, and these relationships were mediated by longer prehospital decision delay. Resilience was related to lower psychological distress post-ACS.

Effect of Type D Personality on Short-Term Cardiac Rehabilitation in Patients With Coronary Artery Disease

Objective

To investigate the effect of type D personality on cardiac rehabilitation (CR) participation rates and the effect of a short-term CR program.

Methods

Study participants included patients diagnosed with acute coronary syndrome who underwent percutaneous coronary intervention. Patients completed the Type D personality Scale (DS-14) and the Hospital Anxiety and Depression Scale (HADS) at program entry. Subjects were recommended participation in 6 weeks of CR exercise training. Cardiopulmonary exercise test (CPET) was conducted before and after completion of the training. CR participation refers to completion of the 6-week CR exercise program and performance of the secondary CPET. Drop-out refers to the subjects who were unable to participate in the 6-week CR exercise program or to perform the secondary CPET.

Results

At baseline, type D personality was evident in 21 of 63 patients (33.3%). Type D patients were more often depressed (57.1%) and anxious (38.1%) than non-type D patients (31.0% and 9.5%, respectively). At baseline, participants with type D personality showed a decreased body mass index (24.6 vs. 26.1 kg/m², p=0.025). The type D group displayed a lower CR participation rate (5/21, 23.8%) compared with the non-type D group of (22/42, 52.4%). Logistic regression analysis revealed the association of type D personality with CR drop-out rate (odds ratio=3.87; 95% confidence interval, 1.2–12.5; p<0.05).

Conclusion

Type D personality was independently associated with drop-out from CR program and with significantly higher levels of anxiety and depressive mood.

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.

Self-care and health-related quality of life in chronic heart failure: A longitudinal analysis

BACKGROUND

Self-care is assumed to benefit health outcomes in patients with chronic heart failure (HF), but the evidence is conflicting for health-related quality of life (HRQOL). The aim of this study was to examine the association of (changes in) self-care with HRQOL while adjusting for psychological distress.

METHODS

In total, 459 patients (mean age = 66.1 ± 10.5 years, 73% male) with chronic HF completed questionnaires at baseline and at 6, 12 and 18 months of follow-up. Self-care and HF-specific HRQOL were quantified with the European Heart Failure Self-care Behaviour scale and the Minnesota Living with Heart Failure Questionnaire.

RESULTS

Using general linear models, multivariable between-subject (estimate = -0.14, p = 0.005) and no within-subject effects of self-care were found for better HRQOL over time. Associations between self-care and HRQOL were fully explained by depression (estimate = 1.77, p < 0.001). Anxiety (estimate = 4.49, p < 0.001) and Type D personality (estimate = 13.3, p < 0.001) were associated with poor HRQOL, but only partially accounted for the relationship between self-care and emotional HRQOL.

CONCLUSIONS

Self-care was prospectively associated with better disease-specific HRQOL in patients with HF, which was fully accounted for by depression, and partially accounted for by anxiety and Type D personality. Changes in self-care within a person did not affect HRQOL. Psychological distress should be considered in future efforts to address self-care and HRQOL.

Medication Adherence Mediates the Association between Type D Personality and High HbA1c Level in Chinese Patients with Type 2 Diabetes Mellitus: A Six-Month Follow-Up Study

Aims. To examine the association between Type D personality and HbA1c level and to explore the mediating role of medication adherence between them in patients with type 2 diabetes mellitus (T2DM). Methods. 330 patients went on to complete a self-report measure of medication adherence and the HbA1c tests. Chi-square test, T test, Ordinary Least Square Regression (OLS), and Recentered Influence Function Regression (RIF) were employed. Results. Patients with Type D personality had significantly higher HbA1c value (P < 0.01). When Type D personality was operationalized as a categorical variable, SI was associated with HbA1c (P < 0.01). When NA, SI, and their interaction term were entered into regression, all of them were no longer associated with HbA1c level (P > 0.1). On the other hand, when Type D personality was operationalized as a continuous variable, only SI trait was associated with HbA1c level (P < 0.01). When NA, SI, and NA × SI term together were entered into regression, only SI was not related to HbA1c level. Furthermore, medication adherence had a significant mediation effect between Type D personality and HbA1c, accounting for 54.43% of the total effect. Conclusion. Type D personality was associated with HbA1c in direct and indirect ways, and medication adherence acted as a mediator role.

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.

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 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.

Type D personality and physical inactivity: The mediating effects of low self-efficacy

Type D personality is associated with health-damaging behaviours among the general population. This study assessed the relationship between Type D personality, physical activity and self-efficacy. A total of 189 participants completed measures of Type D personality, physical activity and self-efficacy. Type D individuals had significantly lower levels of self-efficacy and engaged in significantly less walking and total exercise compared to non-Type D's. Furthermore, self-efficacy fully mediated the relationship between Type D and physical activity. Low levels of self-efficacy may be one mechanism to help explain why Type D individuals engage in more disease-promoting behaviours.

The Clinical Link between Type D Personality and Diabetes

INTRODUCTION

Type D personality consists of a mixture of high levels of negative affectivity and social inhibition, resulting in a stable tendency to experience negative emotions, by inhibiting the expression of these emotions. We have reanalyzed the clinically relevant studies examining the role of this personality profile in diabetes, by providing a qualitative synthesis of the data. In this regard, the aim of this study is to provide a systematic review by evaluating the clinical link between Type D personality and diabetes.

METHOD

When focusing on PRISMA guidelines, we have performed a comprehensive research of the literature on PubMed, Scopus, ScienceDirect, ISI Web of Science, PsycINFO, and Google Scholar by using search terms as "distressed personality" OR (i.e., Boolean operator) "Type D personality" combined with the Boolean "AND" operator with "diabetes."

RESULTS

A total of seven research studies were identified and included in the review. Type D was found to be more prevalent in diabetes patients than controls. As regards the specific association with diabetes variables, Type D personality is a significant predictor of both poor medication adherence and unhealthy behaviors, by predicting negative mental health consequences also (i.e., depressed mood, anhedonia, and anxiety).

CONCLUSION

Our review emphasized for the first time that Type D personality affects clinical factors in patients with diabetes by provoking adverse outcomes. The core implication of the study comprises the clinical relevance to detect, from a clinimetric point of view, Type D personality in diabetes in order to prevent potentially negative clinical outcomes.

Distinct trajectories of disease-specific health status in heart failure patients undergoing cardiac resynchronization therapy

Purpose

It is well known that a significant proportion of heart failure patients (10–44 %) do not show improvement in symptoms or functioning from cardiac resynchronization therapy (CRT), yet no study has examined patient-reported health status trajectories after implantation.

Methods

A cohort of 139 patients with a CRT-defibrillator (70 % men; age 65.7 ± 10.1 years) completed the Kansas City Cardiomyopathy Questionnaire (KCCQ) prior to implantation (baseline) and at 2, 6, and 12–14 months post-implantation. Latent class analyses were used to identify trajectories and associates of disease-specific health status over time.

Results

All health status trajectories showed an initial small to large improvement from baseline to 2-month follow-up, whereafter most trajectories displayed a stable pattern between short- and long-term follow-up. Low educational level, NYHA class III/IV, smoking, no use of beta-blockers, use of psychotropic medication, anxiety, depression, and type D personality were found to be associated with poorer health status in unadjusted analyses. Interestingly, subgroups of patients (12–20 %) who experienced poor health status at baseline improved to stable good health status levels after implantation.

Conclusions

Levels of disease-specific health status vary considerably across subgroups of CRT-D patients. Classification into poorer disease-specific health status trajectories was particularly associated with patients’ psychological profile and NYHA classification. The timely identification of CRT-D patients who present with poor disease-specific health status (i.e., KCCQ score < 50) and a distressed psychological profile (i.e., anxiety, depression, and/or type D personality) is paramount, as they may benefit from cardiac rehabilitation in combination with psychological intervention.

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.

Ankylosing Spondylitis patients with Type D personality have worse clinical status

OBJECTIVES

Type D personality was identified as an important factor that can explain the differences in clinical outcomes in various diseases. The aim of this study is to clarify the relationships between Type D personality and clinical status of patients with Ankylosing Spondylitis (AS).

METHODS

The scores of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Ankylosing Spondylitis Disease Activity Score (ASDAS)-C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR), the Bath Ankylosing Spondylitis Functional Index (BASFI), the 36-Item Short-Form Health Survey (SF-36), and 14-item Type D Scale (DS-14) were noted.

RESULTS

We found significantly higher levels of the BASDAI, the BASFI, and the SF-36 mental subscale scores in patients with Type D personalities compared to those who were Non-Type D (p < 0.05). The total DS-14 scores were found to be correlated with the scores of physical and mental subscales of SF-36, the BASDAI, the BASFI, ASDAS-CRP, and ESR (p < 0.05). In logistic regression analysis, the occurrence of Type D personality was found to be an independent predictor for disease activity of AS due to BASDAI and ASDAS-ESR (p = 0.016, OR, 95% CI = 2.98,1.23-7.22; p = 0.022, OR, 95% CI = 2.78,1.16-6.63 respectively).

CONCLUSIONS

Patients may over-rate self-reported measurements such as the BASDAI, BASFI, and SF-36 related to their interpersonal characteristics. Therefore, including the Type D personality, which is a stable construct in evaluating AS patients with brief and valid DS-14, may be noteworthy.

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.

Comparison of the effects of exercise participation on psychosocial risk factors and cardiovascular disease in women

[Purpose] The aim of this study was to research the association of Type D personality with CVD risk factors and psychology through comparison of the association of exercise participation with CVD risk factors and psychological risk factors in women with Type D. [Subjects] This study included 416 middle-aged women. All participants completed the 14-item Type D Scale (DS14) to assess Type D personality. The DS14 consists of two subscales, NA and SI, both of which comprise 7 items. The research subjects were randomly assigned to four groups: Type D+Exercise (n=12), Type D+non-Exercise (n=12), non-Type D+Exercise (n=12), non-Type D+non-Exercise (n=10). The study consisted of 46 participants. [Methods] An aerobic exercise program and meditation were conducted in parallel for 10 months. Stretching was performed for 10 min as a warm-up, and then walking and running were performed on a treadmill at the HRmax 60–70% level for 40 min; this was done three times a week. Blood samples were processed according to standard laboratory procedures. The concentrations of TG and HDL-cholesterol were determined enzymatically on a clinical chemistry analyzer. Blood glucose was measured by the hexokinase method. [Results] Weight, percent fat, social support, and waist circumference showed a significant difference between times in the Exercise groups, and the values were significantly lower than those of the non-Exercise groups. Anxiety and depression showed a significant interaction effect between groups. The average number of CVD risk factors in subjects showed a significant difference between groups. [Conclusion] In conclusion, there were significant differences between groups in terms of CVD risk factors and psychological risk factors in women with Type D personality.

Type D personality is associated with social anxiety in the general population

BACKGROUND

Research on the emotional processes associated with Type D personality is important for its further conceptualization. We examined the associations of Type D personality with social and general anxiety symptoms in a large community sample.

PURPOSE

The aim of the current study was to disentangle the associations of Type D personality and its components with social anxiety and general anxiety in a large sample from the general population.

METHODS

A random sample of 2,475 adults from the general population filled out questionnaires to assess Type D personality (DS-14), social anxiety (SIAS(10), SPS(11), BFNE-II), and general anxiety (HADS-A, GAD-7).

RESULTS

Type D individuals were characterized by increased levels of both social and general anxiety. The social inhibition (SI) component of Type D personality was most strongly associated with social interaction anxiety (r = .63), while negative affectivity (NA) was strongly associated with general anxiety (GAD-7: r = .70; HADS-A: r = .66). Within social anxiety, SI was more strongly associated with facets of social interaction anxiety than with social phobia. Multiple regression analysis showed that the synergistic interaction of NA and SI was a predictor of social anxiety (SIAS(10): β = .32, p < .0005; SPS(11): β = .27, p < .0005; BFNE-II: β = .11, p = .007) independent of demographics and the scores on the individual Type D components. This interaction was not a significant predictor of general anxiety. Logistic regression using the dichotomous Type D classification demonstrated a 9.1-fold (95%CI, 7.0-11.8) increased odds of a score in the highest quartile of social interaction anxiety and a 7.6-fold (95%CI, 5.8-9.8) increased odds of high social phobia. Odds ratios for clinically relevant levels of general anxiety were 8.3 (95%CI, 5.5-12.5) for GAD-7 and 6.5 (95%CI, 3.4-12.6) for HADS-A.

CONCLUSION

In the general population, Type D individuals were characterized by both social and general anxiety. The SI component of Type D is strongly associated with social interaction anxiety and the synergistic interaction of NA and SI was associated with high social anxiety, above and beyond the main NA and SI effects.

Profiles of self-care management versus consulting behaviors in adults with heart failure

INTRODUCTION

Patients with heart failure (HF) vary in their ability to respond to symptoms when they occur. The goal of this study was to classify common patterns of symptom response behaviors among adults with HF and identify biobehavioral determinants thereof.

METHODS

Consulting behaviors (i.e. contacting a provider for guidance) were measured using the European Heart Failure Self-care Behavior Scale consulting behaviors subscale, and self-care management (i.e. recognizing and engaging in self-initiated treatment of symptoms) was measured with the Self-Care of HF Index self-care management scale in a prospective cohort study. Latent class mixture modeling was used to identify distinct profiles of consulting and of self-care management behaviors.

RESULTS

The mean age (n=146) was 57±13 years, 30% were female, and 59% had class III/IV HF. Two distinct profiles of consulting behaviors (novice and expert) and three distinct profiles of self-care management (novice, inconsistent and expert) were identified. There was a weak association between profiles of consulting behaviors and self-care management (Kendall's tau-b=0.211). Higher levels of anxiety were associated with worse consulting behaviors (β=1.67±0.60) and worse self-care management (β= -5.82±3.12) and lower odds of exhibiting expert level consulting behaviors (odds ratio (OR)=0.50; 95% confidence interval (CI)=0.26-0.95) and self-care management (OR=0.47; 95% CI=0.24-0.92) (all p<0.05). Higher levels of physical symptoms were associated with better self-care management (β=0.50±0.12; OR =1.02, 95% CI=1.00-1.05; both p<0.05).

CONCLUSIONS

Expertise in consulting behaviors does not necessarily confer expertise in symptom self-care management and vice versa. Physical and psychological symptoms are strong determinants of symptom response behaviors.

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.

The relationship between Type D personality, affective symptoms and hemoglobin levels in chronic heart failure

BACKGROUND

Anemia is associated with poor prognosis in heart failure (HF) patients. Contributors to the risk of anemia in HF include hemodilution, renal dysfunction and inflammation. Hemoglobin levels may also be negatively affected by alterations in stress regulatory systems. Therefore, psychological distress characterized by such alterations may adversely affect hemoglobin in HF. The association between hemoglobin and Type D personality and affective symptomatology in the context of HF is poorly understood.

AIM

To examine the relationship between Type D personality and affective symptomatology with hemoglobin levels at inclusion and 12-month follow-up, controlling for relevant clinical factors.

METHODS

Plasma levels of hemoglobin and creatinine were assessed in 264 HF patients at inclusion and at 12-month follow-up. Type D personality and affective symptomatology were assessed at inclusion.

RESULTS

At inclusion, hemoglobin levels were similar for Type D and non-Type D HF patients (p = .23), and were moderately associated with affective symptomatology (r = -.14, p = .02). Multivariable regression showed that Type D personality (β = -.15; p = .02), was independently associated with future hemoglobin levels, while controlling for renal dysfunction, gender, NYHA class, time since diagnosis, BMI, the use of angiotensin-related medication, and levels of affective symptomatology. Change in renal function was associated with Type D personality (β = .20) and hemoglobin at 12 months (β = -.25). Sobel mediation analysis showed significant partial mediation of the Type D - hemoglobin association by renal function deterioration (p = .01). Anemia prevalence increased over time, especially in Type D patients. Female gender, poorer baseline renal function, deterioration of renal function and a longer HF history predicted the observed increase in anemia prevalence over time, while higher baseline hemoglobin was protective.

CONCLUSION

Type D personality, but not affective symptomatology, was associated with reduced future hemoglobin levels, independent of clinical factors. The relation between Type D personality and future hemoglobin levels was mediated by renal function deterioration.

Diabetes MILES--The Netherlands: rationale, design and sample characteristics of a national survey examining the psychosocial aspects of living with diabetes in Dutch adults

BACKGROUND

As the number of people with diabetes is increasing rapidly worldwide, a more thorough understanding of the psychosocial aspects of living with this condition has become an important health care priority. While our knowledge has grown substantially over the past two decades with respect to the physical, emotional and social difficulties that people with diabetes may encounter, many important issues remain to be elucidated. Under the umbrella of the Diabetes MILES (Management and Impact for Long-term Empowerment and Success) Study International Collaborative, Diabetes MILES--The Netherlands aims to examine how Dutch adults with diabetes manage their condition and how it affects their lives. Topics of special interest in Diabetes MILES--The Netherlands include subtypes of depression, Type D personality, mindfulness, sleep and sexual functioning.

METHODS/DESIGN

Diabetes MILES--The Netherlands was designed as a national online observational study among adults with diabetes. In addition to a main set of self-report measures, the survey consisted of five complementary modules to which participants were allocated randomly. From September to October 2011, a total of 3,960 individuals with diabetes (40% type 1, 53% type 2) completed the battery of questionnaires covering a broad range of topics, including general health, self-management, emotional well-being and contact with health care providers. People with self-reported type 1 diabetes (specifically those on insulin pump therapy) were over-represented, as were those using insulin among respondents with self-reported type 2 diabetes. People from ethnic minorities were under-represented. The sex distribution was fairly equal in the total sample, participants spanned a broad age range (19-90 years), and diabetes duration ranged from recent diagnosis to living with the condition for over fifty years.

DISCUSSION

The Diabetes MILES Study enables detailed investigation of the psychosocial aspects of living with diabetes and an opportunity to put these findings in an international context. With several papers planned resulting from a pooled Australian-Dutch dataset and data collections planned in other countries, the Diabetes MILES Study International Collaborative will contribute substantially to identifying potentially unmet needs of those living with diabetes and to inform clinical research and care across the globe.

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.

Type D personality is associated with increased prevalence of ventricular arrhythmias in community-residing persons without coronary heart disease

BACKGROUND

Type D personality may be a risk factor for poor outcome in patients with cardiovascular disease. The biological mechanisms underlying this association are poorly understood. The objective of the study was to test the hypotheses that Type D personality is associated with biological markers for sympathetic dysregulation.

DESIGN

Cross-sectional community-based study.

METHODS

Type D personality was evaluated by DS-14 in 450 persons (46% men), aged between 30 and 65 years. From a Holter-recording, (mean length 18.3 hours), long-term heart rate, ventricular arrhythmias, and heart rate variability (HRV) were registered as markers of sympathetic dysregulation. Traditional cardiovascular risk factors, apnoea-hypopnoea index, medication, and anxiety symptoms were adjusted for.

RESULTS

Type D persons had higher long-term averaged heart rate (74 vs. 71 beats/min, p = 0.003), but this difference was attenuated and not significant in the multivariate model (p = 0.078)). There was an increased prevalence of complex ventricular ectopy (bigeminy, trigeminy, or non-sustained ventricular tachycardia; 14 vs. 6%, p = 0.005 in multivariate model). HRV indices did not differ significantly between those with or without Type D personality. Anxiety symptoms did not confound these associations.

CONCLUSIONS

Type D personality is independently associated with a higher likelihood of ventricular arrhythmias, which may be implicated in the increased cardiovascular risk observed in persons with Type D personality.

The association between Type D personality and illness perceptions in colorectal cancer survivors: a study from the population-based PROFILES registry

OBJECTIVE

To examine the association between Type D personality and illness perceptions among colorectal cancer survivors 1-10years post-diagnosis.

METHODS

Data from two population-based surveys on colorectal cancer survivors was used. Patients diagnosed between 1998 and 2009, as registered in the Eindhoven Cancer Registry, received a questionnaire on Type D personality (DS14) and illness perceptions (B-IPQ); 81% (n=3977) responded.

RESULTS

750 (19%) patients had a Type D personality. They believe their illness has significantly more serious consequences, will last significantly longer, and experience significantly more symptoms that they attribute to their illness. Also, they are more concerned about their illness, and their disease more often influences them emotionally. Differences regarding 'consequences', 'concern' and 'emotional response' were also clinically relevant. The majority of patients stated that the cause of their disease was unknown (23.3%), hereditary (20.3%), lifestyle (15.1%), psychological distress (11.9%) or other (11.6%). Significant differences in perceptions on cause of disease between Type Ds and non-Type Ds were found for psychological distress (16.2 vs. 10.9%; p<0.01), randomness (1.7 vs. 5.3%; p<0.01) and unknown (18.8 vs. 24.4%; p<0.01). Multivariate analyses showed that Type D was negatively associated with 'coherence' and positively with 'consequences', 'timeline', 'identity', 'concern', and 'emotional representation'.

CONCLUSIONS

These results elucidate the associations between personality and illness perceptions, demonstrating their close interrelatedness. Our study may be helpful in further developing theoretical models regarding giving meaning to illness and the illness perceptions that the illness elicits. Future studies should investigate whether interventions can positively impact illness perceptions of Type D cancer patients.

Stress-related hemodynamic response in healthy young individuals with Type D personality

Aim. To investigate the association between the stress-related hemodynamic response during the mental calculation test (MCT) and the presence of Type D personality in healthy young individuals. Material and methods. The study included 80 healthy individuals (19 men and 61 women; mean age 18,8±0,2 years). Psychological status examination included the DS-14 scale, depression scale, and Spielberger-Khanin scale. MCT was performed with simultaneous assessment of hemodynamic response. Results. Type D personality (distressed type) was observed in 32,5% of the participants. Among young students, Type D personality was associated with higher levels of trait and state anxiety (TA and SA), as well as higher depression scale scores, compared to students without Type D personality. Type D personality was also linked to a more pronounced response of systolic blood pressure (SBP) during MCT (p=0,05). There was a strong correlation between social inhibition levels and maximal heart rate (HR) during MCT (r=-0,238; p=0,034). Young men demonstrated a moderate correlation between Type D personality and HR response (r=-0,508; p=0,026), as well as between negative affectivity levels and HR response during MCT (r=0,469; p=0,043). Conclusion. Distressed personality type was observed in one-third of healthy young participants of the study. Type D personality and its subscales correlated with the hemodynamic response during MCT, with some gender-specific features observed. These findings clarify potential mechanisms of Type D personality effects on the development and prognosis of cardiovascular disease.

Type D personality as a cardiovascular risk marker in the general population: results from the Gutenberg health study

BACKGROUND

Type D personality is considered as an independent risk factor for morbidity and mortality in cardiovascular patients and a vulnerability factor for distress in the general population. Because representative community studies are rare, we sought to determine the prevalence of type D personality and its relationship with demographic characteristics, different features of mental disorders, cardiovascular risk factors, health behavior, endothelial function and cardiovascular biomarkers in the general population.

METHODS

The prevalence of type D personality and its correlates were analyzed cross-sectionally in a population-based sample of 5,000 Mid-Europeans aged 35-74 years from the Gutenberg Health Study.

RESULTS

The prevalence of type D personality was 22.2% without remarkable differences in sex distribution. Type D subjects were characterized by lower socioeconomic status, lack of a partnership, increased depression, anxiety, depersonalization and health care utilization. Despite its strong association with mental disorders, type D personality emerged as psychometrically distinct. Although type D personality was independently associated with coronary heart disease (OR = 1.54, p = 0.044), no associations with traditional cardiovascular risk factors were found independently from depression or anxiety.

CONCLUSIONS

Although type D personality is strongly associated with depression, anxiety, impaired mental and somatic health status, and increased health care utilization, the type D construct seems to comprise dysfunctional personality patterns not covered by depression and anxiety scales. Beyond these associations, the pathways of the cardiotoxic impact of type D personality remain to be elucidated. There is a need for prospective population studies on potential links between type D personality and cardiac disease.

Type D (distressed) personality in primary care patients with type 2 diabetes: validation and clinical correlates of the DS14 assessment

OBJECTIVE

In cardiovascular research, Type D personality (high negative affectivity and social inhibition) has been associated with a more than 3-fold increased risk of adverse health outcomes. This study examined the validity and clinical correlates of the Type D construct as assessed by the Type D Scale-14 (DS14) in type 2 diabetes patients.

METHODS

1553 primary care patients with type 2 diabetes were assessed for demographic, clinical, lifestyle and psychological characteristics in 2007. A subgroup (n=1012) completed the DS14 again 1 year later.

RESULTS

The two-factor model of the Type D construct was confirmed in exploratory and confirmatory factor analyses; results were stable across gender. The Negative Affectivity (NA) and Social Inhibition (SI) subscales had adequate reliability in both men and women, as measured by Cronbach's alpha (NA=0.87, SI=0.83), lambda2 (NA=0.87/0.88, SI=0.84), corrected item-total correlations (NA 0.47-0.77, SI 0.34-0.72) and mean inter-item correlations (NA=0.50/0.51, SI=0.42). One year test-retest reliability using intraclass correlation coefficients was 0.64/0.63 for NA and 0.73/0.65 for SI. Type D and non-Type D patients did not differ in vascular history or physiological risk factors, but Type D women had a more sedentary lifestyle (p=.003). Type D patients experienced less social support and more stressful life events, loneliness, and more depressed mood, anhedonia and anxiety (p<.001 for most variables). These differences were clinically significant (Cohen's d>0.60 for most variables).

CONCLUSION

Type D personality can be reliably assessed in primary care patients with type 2 diabetes, and is associated with increased loneliness, stress and emotional distress in these patients.

Type D personality, physical symptoms and subjective stress: the mediating effects of coping and social support

Coping style and social support may represent mechanisms to explain the relationship between Type D personality and ill-health. This study investigated whether Type D is associated with physical symptoms and perceived stress in a non-cardiac population, and if these relationships are mediated by coping and social support. In a cross-sectional study, 304 participants (110 males, mean age 22.1 years) completed measures of Type D, physical symptoms, coping, perceived stress and social support. Results showed that Type D, the interaction of negative affectivity and social inhibition (NA × SI), was positively correlated with physical symptoms, perceived stress, and avoidant coping, and negatively correlated with social support, problem-focused coping and emotion-focused coping. A series of bootstrapped multiple mediator tests showed that social support and avoidant coping fully mediated the relationship between Type D and physical symptoms. Furthermore, social support and emotion-focused coping partially mediated the relationship between Type D and perceived stress. These findings demonstrate for the first time that Type D personality is associated with physical symptoms in a non-cardiac population. Social support and coping style represent mechanisms that can, in part, explain the relationship between Type D and physical symptoms, and Type D and perceived stress.

Association between prehospital delay and subsequent clinical course in patients with/hospitalized for heart failure

BACKGROUND

The clinical consequences of prehospital delay in heart failure (HF) patients are unknown. This study explores the relationship between prehospital delay of HF patients and length of hospital stay, plasma values of brain natriuretic peptides (BNP) as well as the association of delay with all-cause mortality, readmission for HF, or all-cause readmissions during short- (60 days) and long-term (18 months) follow-up.

METHODS

Data from 1023 hospitalized HF patients mean aged 71 years from the Coordinating study evaluating Outcomes of Advising and Counselling in HF study were analyzed.

RESULTS

Patients who delayed less than 1 day had significantly shorter stay in hospital (10 days vs. 11 days, P = 0.033). They also had significantly (P = 0.004) lower median plasma values of BNP (377 pg/mL) at discharge compared to patients who delayed >24 hours (492 pg/mL). Delay was not related to all-cause mortality and/or readmissions for HF.

CONCLUSION

Although patients with a prehospital delay less than 1 day were more symptomatic on admission, they had a shorter hospital stay as well as lower plasma values of BNP at discharge. Delay was not associated hospital readmissions or mortality after discharge.

Health inequalities in the Netherlands: a cross-sectional study of the role of Type D (distressed) personality

Background

In the Netherlands, as in many European countries, inequalities in health exist between people with a high and a low socioeconomic status (SES). From the perspective of the 'indirect selection hypothesis', this study was designed to expand our understanding of the role of Type D personality as an explanation of health inequalities.

Methods

Data came from two cross-sectional Dutch surveys among the general population (aged between 19 and 64 years, response 53.7%, n = 12,090). We analyzed the relative risks of low SES, assessed using education and income, and Type D personality, assessed using the Type D Scale-14 (DS14), for different outcomes regarding lifestyle-related risk factors and health, using multivariate Generalized Linear Models.

Results

Results showed that Type D personality was significantly associated with low SES (OR = 1.7 for both low education and low income). Moreover, the relative risks of Type D personality and low SES were significantly elevated for most adverse health outcomes, unconditionally as well as conditionally.

Conclusion

The cross-sectional design hinders the making of definite etiological inferences. Nevertheless, our findings suggest that Type D personality does not explain the socioeconomic health inequalities, but is a risk factor in addition to low SES. Prevention of adverse health outcomes in low SES populations may have more effect when it takes into account that persons with a low SES in combination with a Type D personality are at highest risk.

Type D personality is associated with impaired psychological status and unhealthy lifestyle in Icelandic cardiac patients: a cross-sectional study

BACKGROUND

Type D (distressed) personality has been associated with adverse cardiac prognosis and poor emotional well-being in cardiac patients, but it is still unclear what mechanisms link Type D personality with poor clinical outcomes in cardiac patients. In the present cohort of Icelandic cardiac patients, we examined potential pathways that may explain this relationship. The objectives were to examine 1) the association between Type D personality and impaired psychological status, and to explore whether this association is independent of disease severity; and 2) the association between Type D personality and an unhealthy lifestyle.

METHODS

A sample of 268 Icelandic coronary angiography patients (74% males (N = 199); mean age 62.9 years (SD 10.5), range 28-85 years) completed the Type D Scale (DS14), Hospital Anxiety and Depression Scale (HADS), and Perceived Stress Scale (PSS) at hospitalization. Health-related behaviors were assessed 4 months following angiography. Clinical data were collected from medical files.

RESULTS

Type D personality was associated with an increased risk of anxiety (OR 2.97, 95% CI:1.55-5.69), depression (OR 4.01, 95% CI:1.42-11.29), and stress (OR 5.99, 95% CI:3.08-11.63), independent of demographic variables and disease severity. Furthermore, fish consumption was lower among Type Ds, as 21% of Type Ds versus 5% of non-Type Ds consumed fish < 1 a week (p < 0.001). Type D patients were also more likely to smoke at follow-up (22% versus 10%, p = 0.024) and to use antidepressants (17% versus 9%, p = 0.049) and sleeping pills (49% versus 33%, p = 0.019) compared to non-Type Ds. Type D personality was not associated with other health-related behaviors, aside from trends towards less fruit and vegetable consumption, and more weight gain.

CONCLUSION

Type D personality was associated with psychological distress and an unhealthy lifestyle in Icelandic cardiac patients. Future studies should further investigate the association between Type D personality and health-related behaviors.

Type D personality, self-efficacy, and medication adherence following an acute coronary syndrome

OBJECTIVE

To assess the relationship among Type D personality, self-efficacy, and medication adherence in patients with coronary heart disease.

METHODS

The study design was prospective and observational. Type D personality, self-efficacy for illness management behaviors, and medication adherence were measured 3 weeks after hospitalization for acute coronary syndrome in 165 patients (mean [standard deviation] age = 61.62 [10.61] years, 16% women). Self-reported medication adherence was measured 6 months later in 118 of these patients. Multiple linear regression and mediation analyses were used to address the study research questions.

RESULTS

Using the original categorical classification, 30% of patients with acute coronary syndrome were classified as having Type D personality. Categorically defined patients with Type D personality had significantly poorer medication adherence at 6 months (r = -0.29, p < .01). Negative affectivity (NA; r = -0.25, p = .01) and social inhibition (r = -0.19, p = .04), the components of Type D personality, were associated with medication adherence 6 months after discharge in bivariate analyses. There was no evidence for the interaction of NA and social inhibition, that is, Type D personality, in the prediction of medication adherence 6 months after discharge in multivariate analysis. The observed association between NA and medication adherence 6 months after discharge could be partly explained by indirect effects through self-efficacy in mediation analysis (coefficient = -0.012; 95% bias-corrected and accelerated confidence interval = -0.036 to -0.001).

CONCLUSIONS

The present data suggest the primacy of NA over the Type D personality construct in predicting medication adherence. Lower levels of self-efficacy may be a mediator between higher levels of NA and poor adherence to medication in patients with coronary heart disease.

Type D personality and metabolic syndrome in a 7-year prospective occupational cohort

OBJECTIVE

Type D personality is a combination of high negative affectivity (NA) and high social inhibition (SI). This trait is related to increased mortality and poor health outcomes in patients with cardiovascular diseases, although it is less well-established if Type D personality also poses an increased risk in healthy populations. A potential underlying pathway could include the metabolic syndrome and the combination of abdominal obesity, subnormal levels of triglycerides and HDL-cholesterol, elevated blood pressure, and increased plasma glucose levels. We investigated if Type D personality shows a cross-sectional and longitudinal association with metabolic syndrome in a working population.

METHODS

Poisson regression and linear regression were used to estimate the association between Type D personality and its subscales (NA) and (SI) with objectively established metabolic syndrome markers in cross-sectional (n=458) and prospective (n=268, 6.3 years follow-up) analyses of data from an occupational cohort (mean age=35.9 years, SD=11.7; 80% male).

RESULTS

Type D personality was neither associated with the metabolic syndrome nor with any of its subcomponents.

CONCLUSION

The present study does not support a role for metabolic syndrome as a mediating mechanism. More research is needed that examines potential pathways linking Type D personality with cardiovascular disease outcomes.
