The concept and measurement of meaning in life in Dutch cancer patients.

We investigated the psychometric properties of a Dutch translation of the Personal Meaning Profile in a heterogeneous group of cancer patients. Our study resulted in a relatively short scale consisting of 39 of the 57 original items, divided into 5 factors, labeled 'relation with God'; 'dedication to life'; 'fairness of life'; 'goal-orientedness' and 'relations with other people', which can be summed to a total score of the experience of meaning in life. The internal consistency of the total scale as well as of its sub dimensions was high. The experience of meaning in life was positively related to feelings of psychological well-being and negatively to feelings of distress. Furthermore, the experience of meaning in life was also related to trait-like characteristics as personality. Future research can investigate its appropriateness for other populations than cancer patients, and if and how the experience of meaning in life eventually changes as a result of existential threats.

A self-rating scale for patient-perceived side effects of inhaled corticosteroids.

BACKGROUND: Patient-reported side effect questionnaires offer a simple method for the systematic measurement of drug-related side effects. In order to measure patients' inhaled corticosteroids (ICS) related side effect perceptions the 14-day retrospective Inhaled Corticosteroid Questionnaire (ICQ) was developed. In this research we aim to assess the construct validity and reliability of the ICQ and test its responsiveness to dose changes in adult asthma patients. METHODS: In a cross-sectional study, current inhaler users with asthma completed the ICQ (27 with non ICS inhaler; 61 BDP equivalent daily ICS low dose < or =400 microg; 62 mid dose 401-800 microg; and 105 with high dose >800 microg). We generated 3 construct validity hypotheses: 1) a hierarchical dose-response pattern for scoring of the individual items on the ICQ, and statistically significant differences in the scores of each of the 15 ICQ domains by ICS dose group 2) an association between ICS dose and ICQ scoring after adjusting for appropriate confounders in multiple regression; 3) greater convergence between local side effect domains than between systemic and local domains of the scale. Test-retest reliability was assessed on a randomly selected subgroup of patients (n = 73) who also completed the ICQ a second time after 7 days. In a separate longitudinal study, 61 patients with asthma completed the ICQ at baseline and after changing their daily ICS dose, at 2- and 6- months, in order to test the ICQ's responsiveness. RESULTS: All three construct validity hypotheses were well supported: 1) a statistically significant difference existed in scores for 14 domains, the high ICS dose group scoring highest; 2) ICS dose independently predicted ICQ scoring after adjusting for confounders; 3) greater convergence existed between local ICQ domains than between local and systemic domains. The ICQ had good reproducibility: test-retest intraclass correlation coefficients were > or =0.69 for all but the 'Facial Oedema' domain. In the longitudinal study, ICQ scores for 'Voice Problems' changed significantly at 2- and 6-months from baseline and other ICQ domains displayed trends in scoring change accordant with dose modulation at 6-months. CONCLUSION: The ICQ has good dose-related discriminative properties, is valid, reliable, and shows potential responsiveness to ICS dose change.

Prescription of beta-blockers in patients with advanced heart failure and preserved left ventricular ejection fraction. Clinical implications and survival.

BACKGROUND: The effects of beta-blockers in patients with heart failure (HF) and preserved left ventricular ejection fraction (LVEF) are not well established. AIMS: To assess the association between beta-blocker prescription at discharge and mortality in a cohort of patients with advanced HF and preserved LVEF. METHODS AND RESULTS: We prospectively studied a cohort of 443 patients with advanced HF and preserved LVEF (LVEF> or =40%). Mean age was 78 years, 56% female, 33% NYHA class IV. Overall, 227 patients (51%) had a beta-blocker prescribed at discharge. Mean duration of follow-up was 25 (+/-18) months. Death (all cause) occurred in 40 patients (17.6%) who were receiving a beta-blocker at discharge and 73 patients (33.8%) who were not on a beta-blocker. In multivariate Cox analysis, including adjustment for propensity score, prescription of a beta-blocker remained associated with a 43% relative mortality risk reduction (HR 0.57, 95% CI 0.37 to 0.88, p=0.01). CONCLUSIONS: In this cohort of patients with advanced HF and preserved LVEF, prescription of a beta-blocker was associated with a significant mortality reduction. This beneficial effect of beta-blocker use needs to be further confirmed in prospective, randomised clinical trials.

Ten-year changes in sun protection behaviors and beliefs of young adults in 13 European countries.

OBJECTIVE: Sun protection behaviors are important to the prevention of skin cancers, but little is known about changes over time in attitudes and behavior. METHODS: Cross-sectional surveys were carried out among university students in thirteen European countries in 1990 (n = 10,241) and 2000 (n = 10,161). Sun protection behavior and beliefs about the importance of sunscreen use for health were measured. RESULTS: There was little change in the proportion of men and women who sunbathed, but use of sun protection increased over the 10-year interval from 52% to 63% in men and 80% to 87% in women. There was wide variation in sun protection use and strength of health beliefs between countries. The association between strength of beliefs and behavior was more marked in 2000 than 1990. Sun protection behavior was positively associated with the socioeconomic background of participants. CONCLUSION: The use of sunscreen increased among educated young Europeans from several countries over the 1990s, but important sex differences remain. Awareness of the risk to health of unprotected sunbathing is high, but there is scope of strengthening attitudes to sunscreen use.

Gender-specific risk factors for mortality associated with incident coronary heart disease--a prospective community-based study.

BACKGROUND: Risk factors for mortality in community-residing persons developing congestive heart failure (CHF) and acute myocardial infarction (AMI) may differ for males and females. METHOD: Persons from the Groningen Longitudinal Aging Study with incident CHF (N=274) or AMI (N=198) were identified between 1993 and 1998 and their survival status was collected in 2001. Risk factors are assessed prior to the cardiac diagnosis. RESULTS: The 1-, 5-, 7-year survival rates were 65, 53, 50% for AMI and 74, 45, 32% for CHF. Multivariate analyses showed that male gender, high age, smoking, diabetes and low physical function were risk factors for mortality among persons with CHF. For AMI, 1 month mortality was related to high age and baseline low body mass index, while longer term mortality was related to male gender and high age. In addition, diabetes increased longer term mortality among females but not among males with AMI. Depression was not a risk factor for mortality for either condition in either gender. CONCLUSION: Males with CHF or AMI have worse survival rates compared to females. Risk factors for mortality are predominantly similar for males and females, except for diabetes which is a risk factor among females, but not males with AMI.

Adjustment to cancer in the 8 years following diagnosis: a longitudinal study comparing cancer survivors with healthy individuals.

This longitudinal study examined the long-term impact of a diagnosis of cancer on physical and psychological functioning, by comparing 8-year cancer survivors (n = 206) to a randomly selected sample of similar-aged references without cancer (n = 120) in the Netherlands. Comparisons were made at three fixed points in time: 3 months (T1), 15 months (T2), and 8 years (T3) after diagnosis. The results showed that, at 8 years after diagnosis, cancer survivors and references do not differ significantly in the level of depressive symptoms, anxiety, life satisfaction, self-esteem, social support, and marital satisfaction. However, survivors reported more physical symptoms, and those with a recurrence of cancer also reported more limitations in household and social activities. Most improvements in functioning were found in the year following diagnosis. Intriguingly, we found no evidence that cancer survivors experienced more positive changes in the self, relationships, or life in general than references, even though many cancer survivors attributed these changes to the cancer experience. In the discussion, we address the role of finding positive meaning in the process of adjustment to cancer.

Depressive symptoms are prominent among elderly hospitalised heart failure patients.

BACKGROUND: There are limited data on the prevalence of depressive symptoms in hospitalised elderly HF patients and demographic and clinical characteristics associated with depressive symptoms are not known. METHODS: A sample of 572 HF patients (61% male; age 71+/-12 years; LVEF 34%+/-15) was recruited from 17 Dutch hospitals during HF admission. Depressive symptoms were assessed by the CES-D. Demographic, clinical variables and HF symptoms were collected from patient chart and interview. RESULTS: Forty one percent of the patients had symptoms of depression with women significantly more often reporting depressive symptoms than men 48% vs. 36% (chi(2)=8.1, p<0.005). HF patients with depressive symptoms reported more clinical HF symptoms than patients without depressive symptoms. Even after deleting HF related symptoms (sleep disturbances and loss of appetite) from the CES-D scale, 36% of patients were still found to have symptoms of depression. Multivariable logistic regression analyses revealed that depressive symptoms were associated with female gender (odds 1.68, 95% CI 1.14-2.48), COPD (odds 2.11, 95% CI 1.35-3.30), sleep disturbance (odds 3.45, 95% CI 2.03-5.85) and loss of appetite (odds 2.61, 95% CI 1.58-4.33). CONCLUSIONS: Depressive symptoms are prominent in elderly hospitalised HF patients especially in women. Depressive symptoms are associated with more pronounced symptomatology, despite the fact that other indices of severity of left ventricular dysfunction are similar.

Psychometric properties of the Dutch version of the posttraumatic growth inventory among cancer patients.

In the current study, we investigated the psychometric properties of a Dutch translation of the posttraumatic growth inventory in a heterogeneous group of cancer patients. Its original five-factor structure was maintained. The internal consistency of the total scale, as well as its subdimensions, was satisfactory. As expected, the experience of posttraumatic growth was positively related to: emotional expression about the illness, openness to experience, and feelings of innerness. Furthermore, the scale appeared to be sensitive for the demographics age and gender. The experience of posttraumatic growth was not related to negative feelings such as avoidance, anxiety, depression, and neuroticism. Our Dutch translation of the instrument appeared to be a sound measure for the experience of posttraumatic growth in cancer patients.

Does marriage protect older people from distress? The role of equity and recency of bereavement.

The association between marital status and distress was examined in a largely neglected group, namely older people (65 and older; N = 1,649). In this 2-wave study, married persons were less distressed than single persons, but perceived equity within the marriage and recency of bereavement qualified these findings. Married persons who felt inequitably treated were more distressed than persons who had always been single. Married persons reported less distress than recently (= 2 years ago) widowed persons, but only equitably treated married persons reported less distress than persons widowed for more than 2 years. Increased distress between the 2 waves occurred in recently widowed persons, and there was a decrease in distress in persons who were widowed shortly before the 1st wave. No gender effects were found.

Risk and protective factors of different functional trajectories in older persons: are these the same?

We examined whether risk and protective factors of different functional trajectories were the same in 1,765 Dutch older persons. We assessed disability in 1993 and reassessed it in 2001. For 2001 as compared with 1993, we distinguished three trajectory groups: substantially poorer, somewhat poorer, and no change or better functioning. We assessed sociodemographic, health, and psychosocial potential risk or protective factors in 1993. When we analyzed them separately, risk and protective factors had similar (but mirrored) associations with functional trajectories. However, in a multivariate approach, we identified old age, depressive symptoms, and low mastery as risk factors for functional decline, whereas we identified young age, good perceived health, and self-efficacy expectancies as factors that predicted trajectories of healthy functioning. Risk and protective factors of functional trajectories in older persons are not the same.

Cancer-related fatigue: predictors and effects of rehabilitation.

BACKGROUND: The aims of the study were to examine the effects of a multidimensional rehabilitation program on cancer-related fatigue, to examine concurrent predictors of fatigue, and to investigate whether change in fatigue over time was associated with change in predictors. METHODS SAMPLE: 72 cancer survivors with different diagnoses. SETTING: rehabilitation center. INTERVENTION: 15-week rehabilitation program. MEASURES: Fatigue (Multidimensional Fatigue Inventory), demographic and disease/treatment-related variables, body composition (bioelectrical impedance), exercise capacity (symptom-limited bicycle ergometry), muscle force (handheld dynamometry), physical and psychological symptom distress (Rotterdam Symptom Check List), experienced physical and psychological functioning (RAND-36), and self-efficacy (General-Self-Efficacy Scale, Dutch version). Measurements were performed before (T0) and after rehabilitation (T1). RESULTS: At T1 (n = 56), significant improvements in fatigue were found, with effect sizes varying from -0.35 to -0.78. At T0, the different dimensions of fatigue were predicted by different physical and psychological variables. Explained variance of change in fatigue varied from 42%-58% and was associated with pre-existing fatigue and with change in physical functioning, role functioning due to physical problems, psychological functioning, and physical symptoms distress. CONCLUSIONS: Within this selected group of patients we found that (a) rehabilitation is effective in reducing fatigue, (b) both physical and psychological parameters predicted different dimensions of fatigue at baseline, and (c) change in fatigue was mainly associated with change in physical parameters.

Changes in personal control as a predictor of quality of life after pulmonary rehabilitation.

OBJECTIVE: Perceptions of mastery and self-efficacy may be related to better outcomes in pulmonary rehabilitation in patients with chronic obstructive pulmonary disease (COPD). This study examined (1) whether patients with COPD improved during a rehabilitation programme with respect to quality of life (QoL) and perceptions of self-efficacy and mastery, and (2) whether increased perceptions of mastery and self-efficacy contributed to a higher QoL after rehabilitation. METHODS: Thirty-nine consecutive COPD patients (aged 60.5 +/- 9.0) were included from a rehabilitation centre and completed self-report questionnaires assessing symptoms, QoL, and perceptions of personal control. RESULTS: COPD patients improved during rehabilitation in overall QoL and self-efficacy, although no significant changes were found in QoL domains and mastery. Changes in self-efficacy during rehabilitation contributed to the explanation of the social and psychological functioning QoL domains. CONCLUSION: Even in seriously impaired COPD patients in advanced stages of illness, positive changes in self-efficacy and overall well-being can be established during rehabilitation. Changes in self-efficacy were related to a better QoL, suggesting the importance of personal control in the adjustment to COPD. PRACTICE IMPLICATIONS: Focussing more explicitly on the enhancement of perceptions of personal control in COPD patients may be an important aim of pulmonary rehabilitation.

Epidemiology of heart failure in a community-based study of subjects aged > or = 57 years: incidence and long-term survival.

BACKGROUND: Survival data from hospital-based or clinical trial studies of patients with chronic heart failure (CHF) do not represent survival in community-based settings. AIMS: To determine the incidence of CHF and the associated long-term survival in a community-based sample aged > or = 57 years and to assess the mortality risk associated with sex and age. METHODS: This study was part of the Groningen Longitudinal Aging Study. RESULTS: Annual incidence of CHF per 1000 ranged from 2.5 in middle aged adults (57-60 years) up to 22.4 in older females (> or = 80 years) and 28.2 in older males (> or = 80 years). The 1, 2, 5 and 7-year survival rates were 74%, 65%, 45%, 32% for patients with CHF, compared to 97%, 94%, 80% and 70% in a matched reference group without CHF. Higher age (> or = 76 years) was a risk factor for mortality (OR = 2.1) and male sex was a risk factor in those aged < or = 75 years (OR = 1.9) but not for older patients. CONCLUSION: Long-term survival rates for patients with CHF in the community were worse than the known survival rates from clinical trials. There is a need for studies describing the care of patients with CHF in the community, including the type of care, the provider, the quality of care and the outcome.

Psychosocial factors associated with indices of cortisol production in women with breast cancer and controls.

The present study was designed to (i) explore which psychosocial factors were associated with indices representing the early morning peak, diurnal cortisol rhythm and area under the curve (AUC); (ii) examine whether the relationships between psychosocial functioning and these cortisol indices were consistent and (iii) explore whether these relationships were influenced by the clinical status of the participant. Newly diagnosed breast cancer patients (n = 85) and healthy control women (n = 59) were recruited. State and trait measures of psychosocial functioning (i.e. anxiety, depression, distress, neuroticism, extraversion, marital satisfaction and mastery) were undertaken. In addition, all participants provided four saliva samples (on waking, 30 min later, between 11 and 1 p.m., before lunch and between 8 and 10 p.m., at least 2h after evening meal) over two consecutive days to assess cortisol levels. The results highlighted the divergent nature of the four cortisol indices; revealed the presence of some significant relationships between the psychosocial measures and the cortisol indices; but highlighted inconsistencies in the relationships evident for patients and those observed for control women.

Beyond stroke: description and evaluation of an effective intervention to support family caregivers of stroke patients.

OBJECTIVE: The objective of this study was to evaluate the strengths and weaknesses of a group support program and a home visiting program for family caregivers of stroke patients. It also examined the best fit between intervention variant and family caregiver and patient characteristics. van den Heuvel's previous effect study showed positive effects of the same intervention program, but unlike our present study differences between the two support variants could not be measured. METHODS: Of 257 family caregivers who were included and randomly assigned to an intervention variant or a control group, 127 family caregivers completed the intervention in either the group program or the home visiting program. RESULTS: Evaluation data showed that both intervention variants had been helpful and feasible, but home visit participants missed peer contact and follow-up contacts were missed in both intervention programs. In comparison to the home visiting program, the group program participants showed more benefit especially with respect to informational and emotional components. Caregivers' preference for type of intervention revealed that both types of intervention had its supporters. Those that preferred the group program could be clearly characterised: they were burdened, lived with a more psychologically handicapped relative, were using active coping strategies more frequently or lived in a region which is considered to be more sociable. CONCLUSION: The present study adds extensively to van den Heuvel's effect study with respect to discriminative aspects of group and home intervention programs and their respective benefits for specific family caregiver groups. PRACTICE IMPLICATIONS: In order to suitably match an intervention type with specific caregiver characteristics the intervention provider should utilize caregiver self-selection or undertake professional screening of caregiver burden. Telephone contacts should be offered in addition to the interventions.

The role of premorbid psychological attributes in short- and long-term adjustment after cardiac disease. A prospective study in the elderly in The Netherlands.

The role of mastery, self-efficacy expectancies and neuroticism in explaining individual differences in physical and psychological adjustment to cardiac disease was studied in 208 patients. Premorbid data were available from a community-based survey in the Netherlands. Hierarchical linear regression analyses showed that self-efficacy expectancies at baseline were significantly related to adjustment in terms of physical functioning in the short- and long-term and depressive symptoms in the short-term (six weeks after diagnosis). Mastery was significantly related to depressive symptoms and anxiety in the long-term (1 year after diagnosis). Neuroticism was a predictor for depressive symptoms and anxiety both in the short- and long-term. The results of this longitudinal study showed that premorbidly assessed psychological attributes do have a role in explaining individual differences in vulnerability to negative consequences of cardiac disease.

Consequences of chronic obstructive pulmonary disease and chronic heart failure: the relationship between objective and subjective health.

This study investigates whether the relationship between objective health parameters and general health perceptions was mediated by symptoms of dyspnoea and physical functioning in patients with chronic obstructive pulmonary disease (COPD) and patients with chronic heart failure (CHF). The different health parameters were organised according to Wilson and Cleary's conceptual model of patient outcomes (Wilson & Cleary (1995). Journal of the American Medical Association, 273, 59-65). Second, we investigated whether perceptions of personal control were related to the health parameters in the model. Consecutive patients with COPD and CHF were included from the outpatient clinics of a university hospital and a general hospital, and from a rehabilitation centre, all in the Netherlands. Ninety-five COPD patients (aged 65.0+/-9.3; forced expiratory volume in 1s (FEV1)<70%) were included and compared with 90 CHF patients (aged 59.6+/-10.0; left ventricular ejection fraction (LVEF)<45%). The relationship between objective health parameters (FEV1 or LVEF) and subjective health (self-reported physical functioning) was not mediated by symptoms of dyspnoea. FEV1 or LVEF and symptoms of dyspnoea were independently related to self-reported physical functioning, which was directly related to general health perceptions. Perceived health competence was related to symptoms of dyspnoea and general health perceptions in patients with either COPD or CHF. Although patients with COPD reported lower levels in all self-reported health parameters in the model than the patients with CHF, this study showed that the relations between the health parameters in the model were comparable for COPD and CHF patients.
