Object Representations and Their Relationship to Psychopathology and Physical Health Status in African-American Women in Primary Care

Object relations theories hypothesize a relationship between self/other representations and level of psychopathology. Research has lent support to this hypothesis. This study was conducted to examine the link between object representation and psychopathology, stress, physical health status, and alcohol abuse in 110 African-American women in primary care. Object representations were assessed through spontaneous descriptions of parents. Psychopathology and physical health status were assessed with the Patient Health Questionnaire and the Medical Outcomes Study Short-Form Health Survey, both of which were designed for medical settings. The results support the link between dimensions of object representations (developmental level, benevolence, punitiveness) and psychopathology and between object representations and aspects of health status. Punitive maternal and paternal representations were most robustly associated with psychopathology and health status and were the only representational variables associated with alcohol abuse. The findings provide additional support for the object representations-psychopathology link and extend the research by demonstrating associations among object representations, alcohol abuse, and health status.

Trägerübergreifendes Projekt zur Früherkennung von Rehabilitationsbedarf bei Versicherten mit muskuloskelettalen Beschwerden durch Auswertung von Arbeitsunfähigkeitsdaten: Ergebnisse einer randomisierten, kontrollierten Evaluationsstudie

In Germany medical rehabilitation has to be initiated by members of statutory pension fund and health insurances. This often leads to delays in the application for and provision of rehabilitation services. Since January 2000 a regional statutory pension fund for blue collar workers (LVA Schleswig-Holstein), 4 statutory health insurances and their medical service MDK have been evaluating a pro-active system to offer rehabilitation to certain member groups. Its acceptance, performance and outcomes were evaluated within a randomized controlled study. Over one year actively insured (i. e. working) members of the a. m. institutions were screened for longer work disability due to musculoskeletal disorders (ICD-10: M05 - 25, M40 - 54, M60 - 99). Based on further inclusion criteria eligible persons were randomized either to an intervention (invitation, counselling, application support) or control (usual care) group. At baseline and six and 12 months all participants completed a postal questionnaire enquiring about various health status aspects (secondary outcomes). Information on sick leave (cases, days), hospital treatment and disability pension was based on administrative data (primary outcomes). Analyses were run on an intention to treat-, per protocol-, as actual-, and matched pairs-basis. 230 persons gave written informed consent (IG: n = 134, KG: n = 96). Within 6 months after study entry 69% of the IG- and 20 % of the KG-members participated in a 3 week in-patient multidisciplinary rehabilitation program. Compared to 6 months prior to the study the occurrence of sick leave due to musculoskeletal disorders was clearly reduced during follow-up between month 6 and 12, however with no significant difference between the two groups. Additionally, IG and CG did not differ in any other primary and secondary outcomes. Contrary to our expectations the IG-members do not seem to benefit from the PETRA-programme including inpatient rehabilitation.

Measurement of Outcome: A Proposed Scheme

The need to demonstrate that health care has an influence on health status is increasingly pressing. Such demonstrations require tools of measurement which are unfortunately not available. Development of instruments has been hampered by a lack of consensus on appropriate frames of reference, and there appears to be little agreement on what should be measured and what relative importance should be ascribed to different dimensions of health status. An approach that does not require the assignment of numerical values or weights to various aspects of health status and is applicable to all age groups within the population and to the whole spectrum of health problems rather than to specific medical diagnoses would seem desirable. A scheme that is based upon the development of a “profile” rather than a single “index” for describing health status is proposed in this paper. The model is a conceptual framework whose usefulness will depend upon efforts of a large number of researchers from many disciplines to develop instruments which can be incorporated in it.Although the problems in development of the scheme are complex, I hope that it will focus attention on the relevant dimensions and facilitate improved coordination of efforts to produce ways to demonstrate what health care contributes to health.

A 12‐month follow‐up study of self‐management training for people with chronic disease: Are changes maintained over time?

A previous study reported some improved outcomes at 4-month follow-up after attendance on a lay-led, chronic disease self-management course (CDSMC). The purpose of this study was to determine whether changes were maintained over time (i.e. at 12 months) and to describe participants' current use of self-management techniques. The study was a 12-month follow-up of a sample of 171 participants who attended a CDSMC in the UK. Data were collected by self-administered questionnaires mailed to participants 12 months after they commenced a CDSMC and via telephone interviews with a sub-sample. The sample had a mean age of 54 years, mean disease duration of 16 years, 73% were women, and chronic diseases included endometriosis, depression, diabetes, myalgic encephalomyelitis, osteoporosis and polio. The significant improvements in outcomes identified at 4 months (i.e. cognitive symptom management, self-efficacy, communication with physician, fatigue, anxious and depressed moods and health distress) were sustained at 12 months. No significant changes between 4- and 12-month assessments were found on any study variables. Interview data confirmed that participants continued to use some of the self-management techniques learned on the course. Attendance on the CDSMC may lead to longer-term changes in key outcomes such as self-efficacy, use of some self-management behaviours and some aspects of health status (e.g. fatigue, depressed mood).

Predictors for work ability and disability in men and women with low-back or neck problems

In many countries back and neck problems are the most common reason for work incapacity. Numerous studies have looked for reliable predictors of return to work (RTW) or not return to work (NRTW) for those incapacitated, but with few exceptions their predictive and detective ability has been limited. We aimed to perform a comparative study of various commonly used health measures ability to predict RTW or NRTW in a cohort of men and women sick-listed for more than 28 days due to low-back pain (LBP) or neck pain (NP). A cohort of 1,575 men and women sick-listed more than 28 days due to back or neck problems was asked to answer ten different health measures (scales) about various aspects of health status (health related quality of life, pain, back function and depressivity) at four occasions during a 2-year period. A statistical diagnostic test was used to study how well the subject's values on these scales would serve as a predictor for work resumption. There was an improvement from day 28 up until 2 years, reflected by the different scales, more pronounced for LBP than for NP patients and for men with LBP compared with women with LBP. For all separately tested scales EuroQol (EQ-5D) had the highest overall ability to predict RTW or NRTW irrespective of gender, diagnoses or duration of the problems. When RTW or NRTW were predicted in a cohort of sick-listed low-back or neck patients, EQ-5D had outstanding properties in this respect irrespective of gender, diagnosis or elapsed time during this 2-year study.

Quality of life in patients with Parkinson's disease

We evaluated the quality of life (QoL) in 278 Indian patients with Parkinson's disease (PD) using PDQL questionnaire, with measures various aspects of health status in PD patients including parkinsonian symptoms, systemic symptoms, social and emotional functions. Apart from demographic and treatment details parkinsonian disability and stage was assessed by Hoehn and Yahr stage, Schwab and England scale and UPDRS scores. We conclude that female gender, presence of depression, low degree of independence, higher levodopa dose (>400 mg/day) and higher UPDRS activity of daily living score have the most detrimental impact on QoL in patients with Parkinson's disease. Depression was the most significant factor impairing the QoL and it needs to be treated.

The Effectiveness of An Acupuncturist Working in General Practice – An Audit

This audit was based in general practice and examined 49 consecutive referrals to a UK trained traditional Chinese acupuncturist. It aimed to assess the type of patients referred to an acupuncturist, subsequent changes in health status, whether the effectiveness of acupuncture was related to the type of presenting problem and to examine which factors were predictive of the success of acupuncture. The referred patients had a wide variety of conditions which were categorised as to whether or not there was empirical evidence from trials of responsiveness to acupuncture (evidence based vs non evidence based). Patients completed measures of their health status prior to treatment and at two and six month follow ups. In addition, the referring GP's beliefs about the prognosis of the problem and the therapist's and patient's expectations of success were measured at baseline. The results showed that referred patients reported poorer health status than a historical sample of general practice patients and that they showed significant improvements in all aspects of health status following acupuncture. In particular, patients showed improved energy, pain, emotional reactions, sleep and reduced social isolation at two months which were maintained at six months. Physical mobility was improved at six months. In addition, the results indicated that the best predictors of effectiveness were the therapist's and patient's expectations of success at baseline. Effectiveness was not related to the category of condition (evidence based or not) nor to the GP's expectations about the prognosis of the condition. The results are discussed in terms of implications for the role of acupuncture in General Practice and selectively targeting patients who would be responsive to such an approach.

Self-assessed health and mortality: could psychosocial factors explain the association?

The single-item question of self-assessed health has consistently been reported to be associated with mortality, even after controlling for a wide range of health measurements and known risk factors for mortality. It has been suggested that this association is due to psychosocial factors which are both related to self-assessed health and to mortality. We tested this hypothesis. The study was carried out in a subsample (n = 5667) of the GLOBE-population, a prospective cohort study conducted in the southeastern part of the Netherlands. Data on self-assessed health, sociodemographic variables, various aspects of health status, behavioural risk factors, and a number of psychosocial factors (social support, psychosocial stressors, personality traits, and coping styles) were collected by postal survey and structured interview in 1991, and mortality data were collected between 1991 and 1998. Cox proportional hazards analyses were used to calculate the association between self-assessed health and mortality, before and after controlling for the psychosocial variables. After controlling for sociodemographic variables, various aspects of health status, and behavioural risk factors, self-assessed health is still strongly associated with mortality in our dataset (Relative Risk [RR] of dying for 'poor' versus 'very good' self-assessed health = 3.98; 95% CI: 1.65-9.61). After controlling for the same set of confounders, many of the psychosocial variables are statistically significantly associated with a 'less-than-good' self-assessed health, particularly instrumental social support, long-lasting difficulties, neuroticism, and locus of control. However, only 'disclosure of emotions'-coping style has a statistically significant relationship with mortality. Adding the psychosocial variables to a model already containing self-assessed health does not attenuate the association between self-assessed health and mortality. We did not find indications that the association between self-assessed health and mortality is due to the psychosocial factors included in this analysis. It seems likely that the unexplained mortality effects of self-assessed health are due to the fact that self-assessed health is a very inclusive measure of health reflecting health aspects relevant to survival which are not covered by other health indicators.

The effects on offspring of premature parturition.

The time of parturition defines the length of the intrauterine period of fetal life, a requisite to achieve adequate adaptation to the external environment. Immaturity, a condition whose severity is inversely related to the length of pregnancy, is the main determinant of the increased morbidity and mortality associated with preterm birth. Despite great advances in medical technology and expertise, mainly after the introduction of the neonatal intensive care units, only one- to two-thirds of infants from the subsets with lower birthweight/gestational age reach survival at discharge. Distinct major neurological and sensorial sequelae, including cerebral palsy, retinopathy of prematurity, and hearing loss, as well as reduced neuropsychological abilities, leading to deficient academic achievement and deterioration of several aspects of health status, are still highly prevalent among the most immature children. Interestingly, decreasing mortality rates, which are not followed by detectable increases of disability, are being observed in recent years. Future advances may be expected from clinical and basic research on uterine contractility and cervical softening. Also, changes in reproductive technology procedures, a main factor in the incidence of multiple pregnancies, and a more refined approach to obstetric care, compose some of the clinical interventions which may reduce the problem.

Recent changes in the health status of the older U.S. population: findings from the 1984 and 1994 supplement on aging.

To examine the changes in the use of health care services, physical functioning, disability, and other aspects of health status in the older U.S. population between 1984 and 1994. The 1984 and 1994 National Health Interview Survey Supplements on Aging, which were national probability samples of the civilian, noninstitutionalized population age 70 and older. A total of 7,541 and 9,447 persons, representing the 17.3 million and 21.8 million U.S. population age 70 and older in 1984 and 1994, respectively. Annual bed-limitation days, doctor visits, episodes and days of hospital stays, limitation in 10 measures of physical performance, disability in seven activities of daily living (ADLs) and six instrumental activities of daily living (IADLs), and participation in social activities and exercise. The annual bed-limitation days and hospital stays declined significantly in both men and women between 1984 and 1994. There was a large decrease in the prevalence of limitation in physical performance and a smaller decrease in disability of IADLs. The changes were greater in women than in men. The prevalence of disability in ADLs was not changed in women in general and increased somewhat in men. Significant increases in the proportion of persons participating in certain social activities and regular exercise were found in both men and women. Jointly considering the indicators, including annual bed days and hospital stays, physical performance, ADLs, and IADLs, 4.2% more men and 3.1% more women were physically robust in 1994 than in 1984. Approximately 420,000 more older people would have lived in a severely restricted and disabled state in 1994 if the rate of limitation had not declined. This study provides evidence of an overall improvement in the health status of older Americans but inconsistency in the trends existed for different disability measures and for population subgroups.

Effectiveness of Hysterectomy

In Brief Objective To measure the effectiveness of hysterectomy in relieving adverse symptoms and to identify factors associated with lack of symptom relief. Methods In a 2-year prospective study, data were collected before and at 3, 6, 12, 18, and 24 months after hysterectomy in 1299 women who had hysterectomies for benign conditions at 28 hospitals across Maryland. Effectiveness was measured in terms of relief of symptoms such as problematic vaginal bleeding, pelvic pain, and urinary incontinence. Psychologic function and quality of life before and after surgery also were assessed. Results Symptom severity, depression, and anxiety levels decreased significantly after hysterectomy and quality of life improved, particularly in the area of social function. However, 8% of women had at least as many symptoms at problematic-severe levels 1 and 2 years after hysterectomy as before. In multiple logistic regression, several presurgical patient characteristics predicted lack of symptom relief, including therapy for emotional or psychologic problems, depression, and household income of $35,000 or less. Bilateral oophorectomy predicted lack of symptom relief at 24 months but not at 12 months after hysterectomy. Conclusion Significant improvements were seen after hysterectomy for all three aspects of health status (symptoms, psychologic function, and quality of life), which persisted or continued to improve throughout the 2 years of follow-up. However, hysterectomy did not relieve symptoms for some women, particularly those who had low incomes or were in therapy at the time of hysterectomy. Hysterectomy relieves symptoms associated with nonmalignant gynecologic disorders and improves psychologic function and quality of life.

Quality of life and health status in pediatric tonsil and adenoid disease.

To assess the baseline global health status and quality of life (QOL) in children with tonsil and adenoid disease. Cross-sectional multicenter survey series. A tertiary academic pediatric specialty hospital and a tertiary academic hospital in 2 different cities. Consecutive series of 55 parents of children who were seen for tonsil and adenoid disease. INTERVENTION AND METHOD: Cross-sectional survey of the health status of affected children to assess their QOL and its relationship to tonsil and adenoid disease. Quality-of-life subscale scores of affected children on the Child Health Questionnaire version PF28 (CHQ-PF28); comparisons of population data from healthy normal children and children with asthma and juvenile rheumatoid arthritis. The overall health status and QOL of children with tonsil and adenoid disease is significantly worse than those of healthy normal children, as demonstrated by lower mean scores on several CHQ-PF28 subscales, including general health, physical functioning, behavior, bodily pain, and parental impact (emotional). In addition, the general health perception of children with tonsil and adenoid disease is similar to the perceptions of children with asthma and juvenile rheumatoid arthritis, but several aspects of health status, as measured by CHQ-PF28 subscale scores, were significantly worse in children with tonsil and adenoid disease. The health status impact of tonsil and adenoid disease appears to be quite significant, particularly in aspects related to the parental impact of the child's disease.

Sacral Rhizotomies and Electrical Bladder Stimulation in Spinal Cord Injury. 2. Cost-Effectiveness and Quality of Life Analysis

Objectives: To present a cost-effectiveness analysis of sacral rhizotomies and electrical bladder stimulation compared with conventional care of neurogenic bladder dysfunction in patients with spinal cord injury. Methods: During a 3-year inclusion period, data on costs and quality of life before the intervention were collected to describe conventional care. Data on the pre-implantation period, the implantation and a follow-up period of 2 years were collected following a strict protocol simultaneous with medical and urodynamic data and were used to calculate the costs and effects on quality of life of the implantation of the stimulator. Results: Between June 1991 and June 1994, 52 patients with complete cervical or thoracic spinal cord lesions underwent sacral posterior rhizotomies and implantation of a Finetech-Brindley sacral anterior root stimulator. Although the initial costs of sacral anterior root stimulation are high, they are earned back in this series in about 8 years after the implantation. General indicators of the quality of life show no significant changes after the implantation. Factors related to psychological well-being and the patients' satisfaction with the emptying of the bladder increased significantly whereas the experienced problems of micturition and incontinence all decreased significantly. Conclusion: Sacral rhizotomies and electrical bladder stimulation make a cost-effective method of treatment of lower urinary tract dysfunction in patients with spinal cord injury. Considerable savings on health care costs are possible in the long run with simultaneous positive effects on aspects of health status.

The benefits of exercise in individuals with traumatic brain injury: a retrospective study.

This study examined the benefits of exercise. A retrospective study. A community-based sample. A sample of 240 individuals with traumatic brain injury (TBI) (64 exercisers and 176 nonexercisers) and 139 individuals without a disability (66 exercisers and 73 nonexercisers). Scales measuring disability and handicap. It was found that the TBI exercisers were less depressed than nonexercising individuals with TBI, TBI exercisers reported fewer symptoms, and their self-reported health status was better than the nonexercising individuals with TBI. There were no differences between the two groups of individuals with TBI on measures of disability and handicap. The findings suggest that exercise improves mood and aspects of health status but does affect aspects of disability and handicap.

Do proxy evaluations of health status predict mortality?

The ability of self-evaluations of health to predict mortality remains despite efforts to explain their contribution. To further the understanding of global evaluations, this study investigated whether proxy evaluations of health status also predict mortality. Data from the Longitudinal Study of Aging were used. For men and women, the unadjusted odds ratios for proxy evaluations exhibited a monotone relationship to 3-year and 7-year mortality rates and were predictive of 7-year mortality. This monotone relationship remained even after controlling for other factors when predicting 7-year mortality rates. However, only the fair and poor evaluations were significant, and only for men. The adjusted relationship when predicting 3-year mortality was not completely monotone, although good and poor proxy evaluations were significant. This suggests that proxy evaluations are useful, and that there are aspects of health status that are currently unmeasured but that should lend themselves to being quantified.

Does the health status of chronically ill patients predict their judgements of the quality of general practice care?

Patients' health status as well as patients' judgements of care are used for assessing patients' perspectives, but the relation between those two concepts is unclear. In this study we explored whether health status predicts patients' judgements of the quality of general practice care. Hand-distributed and mailed surveys were performed by 28 general practitioners in The Netherlands. Chronically ill patients were approached when visiting the general practice or drawn from the practice registers. Health status was measured by WONCA/COOP charts, and patients' judgements by the CEP, a previously validated questionnaire. The response rate was 63% (n = 762). When controlled for other patient characteristics, a poor overall health predicted less positive judgements of medical care, information, counselling, relation and communication, continuity of care and the organization of appointments (p < 0.01). Poor mental well-being predicted less positive judgements of the cooperation between care providers and a stronger need for more care (p < 0.001). The four other aspects of health status did not predict the patients' judgements. Judgements about the premises and the availability for emergencies were not predicted by health status. It can be concluded that a multidimensional approach should be used for interpreting the relations between patients' health status and their judgements of general practice care.

Assessment of patient outcomes after operation for primary hyperparathyroidism

We have used the SF-36, an accepted health status assessment tool, in conjunction with condition-specific clinical information, to assess patient-reported health status before and after operation for primary hyperparathyroidism (1 degree HPT). Beginning in March, 1994, a convenience sample of patients has been asked to complete the SF-36 and provide additional demographic and condition-specific information for study. The SF-36, which measures eight components of functional status and well-being, is completed in person before operation and again by mail at 2 and 6 months after operation. Clinical and condition-specific data are gathered at the same times. Fifty-nine patients have entered the study; 56 had abnormal parathyroid tissue removed. Patients with 1 degree HPT have lower SF-36 scores in all health domains at baseline than do healthy patients. At 2 months, scale scores for emotional role limitations and bodily pain improved by more than 10 points. At 6 months all eight scale scores showed improvement, seven of eight by 10 points or more. Commensurate improvements in HPT-specific measures were also seen. Patient-reported measurements of health outcomes after parathyroidectomy for 1 degree HPT show improvement in all aspects of health status 6 months after operation. Most dramatic improvements were reported in reduction of bodily pain and in improved vitality and emotional and physical function. Surgical correction of 1 degree HPT improves patient health status and quality of life.

Health status, adherence with health recommendations, self-efficacy and social support in patients with rheumatoid arthritis

A study was performed in 86 patients with rheumatoid arthritis (RA) to assess their health problems, the problems they experience in adhering to health recommendations and the relationships of these problems with self-efficacy and social support. Feeling dependent, disability and pain were the most important health related problems. The results showed self-efficacy to be related to the subjective experience of health status as measured by DUTCH-AIMS. Social emotional support was not related to health status and contrary to what we expected social instrumental support was positively related to health status. The majority of the patients (55%) experienced adherence problems with health recommendations. These problems were not related to functional incapacity, pain or other aspects of health status but to the patient's self-efficacy expectations about coping with arthritis. Our conclusion is that to improve the self-management of disability and pain and adherence to health recommendations, patient education should be aimed at strengthening self-efficacy expectations in which social emotional support might be a motivating factor.

Correlated nondifferential misclassifications of disease and exposure: application to a cross-sectional study of the relation between handedness and immune disorders.

In cross-sectional studies, misclassifications of exposure and of health status may be related. For instance some subjects may tend to overreport both exposure and disease. A misclassification is said to be nondifferential if the sensitivity and the specificity which characterize it do not depend on the true status of the subjects for the other variables. Nondifferential misclassifications of two dichotomic variables may be correlated if the probability of being misclassified for one of them depends on the presence of an error of classification for the second one. Models are presented to estimate the bias induced by correlated nondifferential misclassifications on an odds ratio whose true value is unity. For most usual situations, when the great majority of the subjects are healthy and nonexposed, the influence of overreporting is shown to be larger than that of underreporting. It appears to be relatively easy to find a spurious, but significant, relationship. Real data are analysed to show that the potential consequences of correlated nondifferential misclassifications are not purely theoretical. In a sample of 1676 subjects from the general population we observed significant relations between left-hand shift and various aspects of health status: reporting a history of eczema, experience of a serious health problem in the past, experience of a serious health problem presently, use during the last month of analgesics or of drugs for circulatory problems, or digestion, consultation with a physiotherapist or hospitalization during the last year. These results, as with many similar ones previously reported, are highly suggestive of an information bias. They are less easily explained by biological hypotheses, e.g. Geschwind's theory of cerebral lateralization, than by correlated misclassifications resulting from overreporting of both the use of the left hand and the existence of some health problems by healthy right-handers. The modelling used in this report supports this hypothesis.
