Relationships between social functioning and quality of life in a population of Dutch adult psychiatric outpatients.

BACKGROUND: The relationship between social functioning and QOL in psychiatric patients has not been explicitly investigated before. AIMS: To investigate the relationship between social functioning and QOL in a population of psychiatric outpatients (N = 410) with a broad spectrum of psychiatric disorders. METHOD: Social functioning was assessed with the Groningen Social Behavior Questionnaire-100 (GSBQ-100) and the Global Assessment of Functioning (GAF) scale. QOL was measured with the WHO Quality of Life Assessment Instrument (WHOQOL-100). RESULTS: The study population experienced a wide range of problems concerning all aspects of social functioning. The numbers of problems were significantly higher compared with healthy controls and (partly) also compared with a norm group of psychiatric outpatients. Almost all scales of the GSBQ-100 were negatively correlated with all QOL aspects, whereas the GAF score correlated positively with all QOL aspects. In general, participants with problems on aspects of social functioning had lower QOL scores than those without such problems, even after a correction for the presence of psychopathology according to DSM-IV classification. CONCLUSION: In addition to the presence of psychopathology, social functioning is significantly related to QOL. Therefore, it should be considered more systematically in psychiatric assessment, treatment and program evaluation.

Relationships between demographic variables and quality of life in a population of Dutch adult psychiatric outpatients.

BACKGROUND: Examinations of the role of demographic characteristics in quality of life (QOL) in psychiatric samples are not new. However, serious limitations of previous research have been that (1) QOL was not assessed according to current recommendations, (2) assessment of QOL was often hampered by a substantial overlap in content between symptoms and QOL measures, and (3) the majority of the study samples had quite specific characteristics hampering the generalizability of results, as a result of which clinical implications of the results remained unclear. The aim of the present study was to investigate explicitly the relationships between demographics and QOL in a sample reflecting the general population of psychiatric outpatients, QOL being assessed in a comprehensive, culturally sensitive, and subjective way, paying attention to the relative importance of its various facets. The main hypothesis was that these relationships would be rather weak. METHOD: From a population of 533 adult Dutch psychiatric outpatients, 495 participants completed the World Health Organization Quality of Life (WHOQOL)-Bref for assessing QOL. Furthermore, several demographic characteristics were recorded. RESULTS: Statistically significant correlations were found between partner relationship, habitual status, work, and sick leave and the WHOQOL-Bref domains social relationships and environment. Psychological health was associated to partner relationship, educational level, and sick leave. The total amount of QOL variance explained by demographics was rather low. CONCLUSION: Amongst factors determining QOL, demographic characteristics are relatively unimportant. Therefore, paying attention to demographics during psychiatric treatment will probably have little effect on improvement of QOL.

Assessment of disease impact in patients with intermittent claudication: discrepancy between health status and quality of life.

OBJECTIVE: To describe similarities and differences between health status and quality of life in patients with intermittent claudication. METHODS: This was an observational study in the vascular outpatient department of a teaching hospital; it concerned 200 consecutive patients with intermittent claudication. Health status was assessed with the RAND-36, and quality of life was assessed with a reduced version of the World Health Organization Quality of Life assessment instrument-100. Scores were compared with those of sex- and age-matched healthy controls. Mann-Whitney U tests were used to detect statistically significant differences ( P < .01) between patients and healthy controls. Pearson correlations were calculated between health status and quality-of-life scores. Differences between correlations were examined by using Fisher z statistics. The upper and lower 10% of quality-of-life scores were compared with the response quartiles of the health status scores. RESULTS: Health status was significantly impaired in all domains. Quality of life was significantly worse with respect to aspects of physical health and level of independence and one global evaluative facets overall quality of life and general health. Quality-of-life assessment with the World Health Organization Quality of Life instrument disclosed patient-reported problems that had not been identified in health status. Conversely, patients did not regard all objective functional impairments as a problem. Pearson correlations ranged from 0.20 to 0.74. There were patients with excellent and very poor quality-of-life scores in nearly all the quartiles of the corresponding health status domains. CONCLUSIONS: Health status and quality of life represent different outcomes in patients with intermittent claudication. In addition to functional restrictions as measured in health status, quality of life also permits a personal evaluation of these restrictions. Objective functioning and subjective appraisal of functioning are complementary and not identical. Combining these measures should direct treatment in a way that meets patients' needs.

The effect of episodic anxiety on an in vitro fertilization and intracytoplasmic sperm injection treatment outcome: a pilot study.

This study examines whether the inconsistent and contradictory findings from prospective studies on the effect of psychosocial factors on treatment outcome of in vitro fertilization (IVF) can be explained by the fact that no clear distinction has been made between acute and chronic emotional stress responses. Because chronicity is difficult to measure within the context of an IVF-procedure, the focus of the present study was on episodic anxiety. We compared its predictive value on treatment outcome after the second IVF and intracytoplasmic sperm injection (ICSI) with the predictive value of trait anxiety and acute anxiety. In a prospective study with 47 women who failed to conceive after the first IVF, state anxiety was measured both before and after the first IVF treatment. Episodic anxiety was operationalized as high state anxiety both before and after the first IVF treatment Student's t-test and logistic regression analysis were used to determine the predictive value of episodic anxiety compared with acute or trait anxiety. Women with episodic anxiety, but not those with high levels of trait or acute anxiety, were less likely to become pregnant after the second IVF/ICSI. The results suggest that future studies should differentiate between acute and chronic stress, when examining the effects of psychosocial factors on treatment outcome after a fertility treatment

Assessment of fatigue among working people: a comparison of six questionnaires.

AIMS: To compare the psychometric qualities of six fatigue questionnaires in a sample of working persons. METHODS: Internal consistency and test-retest reliability, content validity, convergent validity, and the dimensionality of the fatigue instruments were explored. RESULTS: All scales had a satisfactory internal consistency. Furthermore, based on factor analyses and Mokken scale analyses, all scales were unidimensional and appeared to measure an identical construct. The Fatigue Assessment Scale (FAS) had the highest factor loading on the one factor solution obtained in a factor analysis of the total scores of all scales. CONCLUSIONS: All the questionnaires were unidimensional and had good reliability and validity. The FAS was the most promising fatigue measure.

The impact of walking impairment, cardiovascular risk factors, and comorbidity on quality of life in patients with intermittent claudication.

OBJECTIVE: The objective of this study was to assess the impact of walking impairment, cardiovascular risk factors, and comorbidity on quality of life (QOL) in patients with intermittent claudication (IC). MATERIAL AND METHODS: The prospective observational study was conducted in the setting of a vascular outpatient department of a teaching hospital. QOL was assessed in 200 consecutive patients with IC, with a reduced version of the World Health Organization Quality of Life Assessment Instrument-100. The reduced instrument assesses 17 facets of QOL within five domains (Physical and Psychological Health, Level of Independence, Social Relationships, and Environment). Age, gender, degree of IC, risk factors, comorbidity, as recommended by the Society for Vascular Surgery/North American Chapter of the International Society for Cardiovascular Surgery (SVS/ISCVS), and the presence of back, hip, or knee symptoms were analyzed as possible predictors of QOL. Multiple regression analyses were run with each of the QOL facets and domains as dependent variable. A probability value of less than.05 was considered to be statistically significant. RESULTS: Male gender was found to be a predictor of better scores for Energy and Fatigue and for Sleep and Rest. Women had more Negative Feelings. The presence of back, hip, or knee symptoms was a significant predictive value for many aspects of QOL. With more concomitant diseases, patients had lower scores on the facets of Overall QOL and General Health and of Energy and Fatigue and showed more dependence on medication and treatments. The degree of IC, as expressed in the SVS/ISCVS classification, was a statistically significant predictor of QOL on the domain Level of Independence and its facets Mobility, Activities of Daily Living, and Working Capacity and the facets Pain and Discomfort, Sexual Activity, and Transport. Hypertension was the second most important single predictor of QOL in patients with IC. CONCLUSION: QOL in patients with IC is only partially determined by the severity of walking limitation as expressed in the SVS/ISCVS classification. The significant impact of cardiovascular risk factors and comorbidity and the presence of back, hip, or knee symptoms on QOL should be recognized and taken into account in the treatment policy.

Hypertension and appraisal of physical and psychological stressors.

OBJECTIVE: In the operant conditioning of hypertension hypothesis, it is assumed that the frequently found diminished sensitivity to painful stimuli in hypertensives can be generalized to sensitivity to other stressors, including psychological stressors. The validity of this assumption is examined in the present study. METHODS: Unmedicated hypertensives (42) and normotensive controls (21) of both sexes were exposed to a physical stressor (electric current) and psychological active coping (mental arithmetic, free speech) and passive coping (unpleasant films) tasks, while indices of prestressor anxiety and task appraisal were measured. RESULTS: Hypertensive women, but not men, showed diminished pain sensitivity, together with lower prestressor anxiety and a tendency to lower negative appraisal of the tasks, compared to their normotensive counterparts. In addition, positive correlations were obtained between pain sensitivity and negative appraisal of psychological stressors involving interpersonal threat (speech) and passive coping (films). CONCLUSION: Preliminary support has been obtained for extrapolation of diminished pain appraisal to appraisal of some psychological stressors (although for a part only in women); an important assumption in the operant conditioning hypothesis of hypertension.

Measuring depression in women around menopausal age: towards a validation of the Edinburgh Depression Scale.

BACKGROUND: The relationship between menopause and depression is still rather unclear. Studies using different methodology - especially those lacking a clear definition of depression - are hardly comparable. Since the Edinburgh Depression Scale (EDS) is not influenced by (menopause-related) somatic symptoms, the validity of the Dutch version of this instrument was investigated in a large community sample of menopausal women. METHODS: In 951 women, aged between 47 and 56 years, depressive symptomatology was measured using the EDS, together with a syndromal diagnosis of depression using Research Diagnostic Criteria. RESULTS: Twenty-two percent of the subjects had scores of 12 or higher on the EDS. With this cut-off point, depression (major or minor) was detected with a sensitivity of 66%, a specificity of 89%, and a positive predictive value (PPV) of 62%. A cut-off score of 15 or higher detected half of the women with major depression (sensitivity 73%, specificity 93%, PPV 53%). LIMITATIONS: Screening of depressive symptomatology at menopausal age in women of the community can only partly detect women with clinical depression. The relation between menopausal status and depression should preferentially be investigated using a longitudinal rather than a cross-sectional design. CONCLUSIONS: The EDS, which is easy to implement in both community and clinical settings (e.g., General Practice), might be used as an effective screening tool for detecting women at menopausal age who are at risk for depression, followed by clinical evaluation in those with high scores.

An exploratory investigation into types of adult homesickness.

BACKGROUND: It is not clear yet whether or not homesickness is a singular syndrome. Some authors have proposed different subtypes or forms of homesickness. Since there may be great differences between various subtypes of homesickness regarding etiology, causes, manifestations and consequences, a distinction of subtypes may have far-reaching implications for research and therapy. This exploratory study was conducted to find out whether homesickness can be considered a homogeneous syndrome, or whether there are distinct subtypes that differ in etiology, severity of the condition and manifestations. METHOD: Thirty-one individuals, who have had severe homesickness experiences, were interviewed, and verbal scripts were typed out. Twenty-four interviews were suited for analyses. All text related to the topics most relevant to the purpose of the study was extracted. The text was first analyzed searching for meaning and categories and afterwards coded and used in a HOMALS analysis. RESULTS: The HOMALS analysis yielded two dimensions. The first dimension can be described as a dimension of psychopathology differentiating 'recovered' and recurrent homesickness. The second dimension was strongly dominated by homesickness during holidays. CONCLUSIONS: It seems that there are reasons to presume the existence of at least two subtypes of homesickness: (1) recurrent homesickness related to signs of psychopathology and recurrent homesickness experiences and (2) recovered homesickness, which can be considered as a normal adjustment problem which most people overcome. Very tentatively, a third type of homesickness might be distinguished: holiday homesickness, which is associated with difficulties in breaking with old routines. Consequences for research and therapy are discussed. Furthermore, the need of validation studies is underlined.

Hypertension and pain sensitivity: effects of gender and cardiovascular reactivity.

Repeatedly, hypertensives have been found to appraise physical stressors as less aversive than normotensives. The main aim of the present study was to examine the effects of gender and cardiovascular reactivity in the relationship between hypertension and appraisal of pain. Forty-two unmedicated hypertensives and 21 normotensive controls of both genders were exposed to an electric current stimulus, while various cardiovascular parameters and prestressor anxiety were measured. In general, hypertensive women, but not men, showed diminished pain sensitivity compared to their normotensive counterparts. When the analyses were repeated with controlling for cardiovascular reactivity, the between-group effects were no longer significant. The results indicate that (i) profound gender differences exist in hypertension-related pain sensitivity and (ii) these effects seem to be mediated, at least partly, by cardiovascular reactivity.

Impairment of quality of life: rheumatoid arthritis versus sarcoidosis.

BACKGROUND: Quality of life (QOL) has become an important item in health care. QOL should be a major target of treatment in chronic diseases such as rheumatoid arthritis (RA) and sarcoidosis. The aim of this study was to compare the impact of RA and sarcoidosis on patients' QOL. We expected more serious impairment of QOL in the RA group than in the sarcoidosis group. METHODS: QOL was studied in RA patients (n = 32), sarcoidosis patients (n = 37), and a healthy control group (n = 37) employing the World Health Organization Quality of Life assessment instrument (WHOQOL-100). RESULTS: In both patient groups QOL was impaired with respect to Physical Health, Level of Independence (P < 0.001), and Overall QOL and General Health (P < 0.01). Moreover, RA patients appeared to have a lower QOL with respect to Pain and Discomfort (P < 0.001) and Mobility (P < 0.001). CONCLUSIONS: In RA and sarcoidosis, fatigue and sleep were major problems. In contrast to our expectations, with respect to activities of daily living and working capacity, the two patient groups did not show any difference. Impairment of QOL was more serious and included more aspects of QOL in RA than in sarcoidosis.

Gender differences in sarcoidosis: symptoms, quality of life, and medical consumption.

The aim of this study was to examine gender differences in quality of life (QOL) and in constitutional symptoms that coincide with sarcoidosis. The study population included 1026 sarcoidosis patients--all members of the Dutch Sarcoidosis Society--who completed the WHOQOL-100 and a symptom checklist. Women experienced more symptoms than men. With regard to QOL, male and female patients who suffered from symptoms differed in the broader domains of Physical Health and Psychological Health. Specific facets reflected pain, sleep, positive affect, appearance, mobility, and activities of daily living. Future studies should focus on the different experience of the disease between male and female patients more extensively. Studies are needed to evaluate whether the differences in the present study between male and female sarcoidosis patients are caused by a subject selection bias or life style differences; have a genetic, hormonal or biological base; or just are an epiphenomenon.

Elevated blood pressure and self-reported symptom complaints, daily hassles, and defensiveness.

The association between elevated blood pressure and low rates of self-reported problems has been hypothesized to be mediated by defensiveness. In a population screening study in which 1,120 women and 903 men between 20 and 55 years of age participated, multiple resting home blood pressure measurements were performed and questionnaires were administered measuring symptom complaints, daily hassles, and defensiveness. In women, after control for potential confounders, a low number of self-reported symptoms was associated with elevated blood pressure. However, this effect was not mediated by defensiveness, although repressive defensiveness predicted independently elevated blood pressure in women. In men, no significant associations were obtained. Furthermore, no relations emerged between daily hassles and elevated blood pressure. In conclusion, although defensiveness was more prevalent among women with elevated blood pressure, it does not provide a good explanation for the low rates of self-reported symptoms found in these women.

Quality of life in sarcoidosis: a comparison between members of a patient organisation and a random sample.

UNLABELLED: BACKGROUND AND AIMS OF THE WORK: Although it often has been suggested that members of patient organisations concerning a particular disease might not be representative of patients with that particular disease in general, this hypothesis has not been tested. Therefore, the aim of this study was to evaluate whether the quality of life (QOL) of members of the Dutch Sarcoidosis Society (DSS) is comparable with the QOL of a random non-member sample of the Dutch sarcoidosis population. SUBJECTS AND METHODS: The study included 64 out-patients (Group I), 192 DSS members matched for age and gender (Group II), and 192 DSS members matched for age, gender, as well as symptoms (Group III). All subjects filled in a questionnaire to make an inventory of physical symptoms and the World Health Organization Quality of Life assessment instrument (WHOQOL-100). The Student's t-test was used to evaluate the differences between (i) the two DSS groups and (ii) the non-member group. RESULTS: Group III differed significantly from Group I in only one QOL domain and five facets. Moreover, considering only the patients with symptoms from Group I and Group III, differences emerged on one domain and two facets. CONCLUSIONS: It appeared that more members of the DSS declared they suffered from physical symptoms than non-members. When the experience of symptoms was partialled out fewer QOL differences remained.

Evaluation of quality of life in sarcoidosis patients.

Health-related quality of life (QOL) has become an important topic in health care. However, hardly any attention has been paid to QOL in sarcoidosis. Therefore, the aim of this study was to assess the impact of sarcoidosis on QOL. Sixty-four sarcoidosis patients completed the World Health Organization Quality of Life assessment instrument (WHOQOL-100) and the Beck Depression Inventory (BDI). For the WHOQOL-100 a matched group of healthy controls was selected. Patients were divided into two groups: group I (n = 37) consisted of patients with actual symptoms, group II (n = 27) consisted of asymptomatic patients. The WHOQOL-100 revealed a number of areas in which sarcoidosis patients, especially those with current symptoms, experienced problems. A major symptom in both groups of sarcoidosis patients was fatigue. No association between the facet fatigue and the domain psychological health was found. Depressive symptoms (BDI) were associated with psychological function (WHOQOL-100). No association between pulmonary function tests and QOL was found. In conclusion, this study shows that sarcoidosis has a considerable impact on the QOL of patients. The WHOQOL-100 appeared to be a sensitive instrument to measure fatigue--one of the most common symptoms in sarcoidosis--which otherwise is difficult to assess objectively.

Defensive coping in relation to casual blood pressure and self-reported daily hassles and life events.

Our aim was to investigate the relationships between defensiveness and repression, on the one hand, and self-reported stressor exposure and resting blood pressure, on the other hand. In addition, different operationalizations of defensiveness and repression were compared. Participants were 310 male and 90 female employees representing a wide range of occupations. Before a medical examination, all subjects completed questionnaires measuring defensiveness, anxiety, repression, daily hassles, and life events. After controlling for potentially confounding variables, multiple regression analyses revealed an inverse association between defensiveness and self-reported number of daily hassles and a positive link between defensiveness and resting systolic blood pressure. In general, the interaction between defensiveness and anxiety (representing repression) did not add to the predictive power of defensiveness and anxiety alone. The results support the notion that defensive individuals tend to underreport problems, while exhibiting elevated resting blood pressures.

Prenatal diethylstilbestrol exposure and self-reported immune-related diseases.

OBJECTIVE: To compare self-reports of immune-related diseases in diethylstilbestrol (DES) daughters and controls. Prenatal exposure to DES has been associated with several malformations in the lower genital tract, a higher prevalence of adenosis, and increased risk of clear cell adenocarcinoma, and estrogen-dependent tumors. Lately, reports have been published indicating a link between DES exposure and alterations in the immune system. The present study focuses on the possible clinical consequences of an affected immune system. STUDY DESIGN: DES daughters (n=170) and control women (n=123) completed questionnaires containing lists of immune-related diseases, specified into three categories (i) allergies, (ii) auto-immune disorders, and (iii) infectious diseases. RESULTS: DES daughters reported significantly more disease conditions than the controls. Analyses for separate disease categories (allergies, auto-immune disorders, infectious disease), yielded a statistically significant difference only for infectious disease. Within this last category, two infectious diseases yielded highly significant differences: bladder infection and measles. CONCLUSION: The present findings suggest that DES daughters are at higher risk of developing immune-related disease states.

Blood pressure, self-reported symptoms and job-related problems in schoolteachers.

The relationship between blood pressure and self-reports of physical symptoms and job-related problems was investigated in a sample of 262 male and female teachers. The subjects were divided into three groups: treated hypertensives (THT, N = 23); untreated hypertensives (UHT, N = 101); and normotensives (NT, N = 123). After controlling for eight potentially confounding variables, the groups differed significantly with respect to reported physical symptoms, with THT reporting the most and UHT the fewest symptoms. Moreover, after controlling for potential confounders, a multiple regression analysis revealed an inverse association between diastolic blood pressure and the number of reported physical symptoms in untreated subjects. A similar trend for systolic blood pressure did not reach significance. In addition, no significant results with respect to work-related problems were obtained, except for a group x gender interaction on job-related irritation: male THT showed lowest and female THT highest irritation scores. The potential role of altered appraisal, diagnosis, and gender are discussed.

Homesickness: a review of the literature.

Homesickness has not received due attention from psychological researchers, in spite of the fact that it is of considerable interest to counsellors and care-givers of those who have migrated or moved temporarily or permanently (e.g. immigrants, refugees, students, soldiers). First, this review addresses the definition of homesickness, the possible different kinds of homesickness, its prevalence rate, and symptomatology, Secondly, an overview is given of the theories that account for psychological distress following leaving home. These theories link homesickness with separation-anxiety and loss, the interruption of lifestyle, reduced control, role change, and internal conflict. In addition, the review focuses on: (i) studies that show that subjects reporting homesickness differ from non-homesick persons in terms of personality; (ii) the analyses of environmental characteristics that may play a crucial role in the onset and course of homesickness. Thirdly, Fisher's (1989) composite model of homesickness, which summarizes key findings of the major studies on homesickness is discussed. Fourthly, methodological issues are addressed. Finally, suggestions for future research are presented and possibilities for interventions are proposed.
