Self-report measures for assessing treatment outcomes in cardiac surgery patients.

Patient self-report measures are increasingly valued as outcome variables in health services research studies. In this article, the authors describe the Functional Status, Health Related Quality of Life, Life Satisfaction, and Patient Satisfaction scales included in the Processes, Structures, and Outcomes of Cardiac Surgery (PSOCS) cooperative study underway within the Department of Veterans Affairs health care system. In addition to reporting on the baseline psychometric characteristics of these instruments, the authors compared preoperative Medical Outcomes Study SF-36 data from the study patients with survey data from a probability sample of the US population and with preoperative data on cardiac surgery patients from a high volume private sector surgical practice. Descriptive analyses indicate that the SF-36 profiles for all of the cardiac patients are highly similar. The Veterans Affairs and private sector patients report diminished physical functioning, physical role functioning, and emotional role functioning as well as reduced energy relative to an age-matched comparison sample. At the same time, however, the Veterans Affairs patients evidenced lower levels of capacity on most of the SF-36 dimensions relative to the private sector patients.

Do internal standards of quality of life change in lung cancer patients?

BACKGROUND: Measurement of health-related quality of life (QOL) over time often yields results that may be difficult to understand. Patients may change their internal standards of QOL as a result of adaptation to deteriorating health, a phenomenon referred to as response shift. OBJECTIVES: To examine changes in internal standards of fatigue, global health/QOL, and physical function in patients with inoperable lung cancer at 3 months (n = 115) and 6 months (n = 89) after a baseline measurement close to diagnosis. Significant changes were expected to occur only in patients who reported improvement or deterioration in fatigue and global health/QOL. METHODS: Fatigue, global health/QOL, and physical function were assessed with the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30, version 3.0). At follow-up, this questionnaire was administered conventionally and as a retrospective baseline assessment (thentest). Subjective transition questions were used to form mutually exclusive patient subgroups (i.e., deterioration, stable, or improvement). RESULTS: With respect to fatigue, significant changes occurred in patients reporting deterioration at 3 months follow-up and in patients reporting improvement after 6 months, but not in patients reporting improvement after 3 months or deterioration after 6 months. Significant changes in global health/QOL were found in patients reporting improvement at both 3 and 6 months follow-up and unexpectedly in stable patients after 3 months. No significant changes were found in patients reporting deteriorated global health/QOL at 3 and 6 months. Unexpectedly, changes occurred at both 3 and 6 months in patients reporting improved physical function. DISCUSSION: Given these mixed findings, it cannot be concluded that changes in internal standards occurred. These severely ill patients reported high levels of symptoms at baseline and may in part have adapted to their symptoms before study entry.

The Fibromyalgia Impact Questionnaire: a validated Spanish version to assess the health status in women with fibromyalgia.

OBJECTIVE: To translate, adapt, validate and assess the sensitivity to change of a Spanish version of the Fibromyalgia Impact Questionnaire (FIQ-S). METHODS: The FIQ-S was adapted following the translation and back-translation methodology. Female patients with fibromyalgia (FM) were invited to participate. Reliability was analyzed by the Spearman correlation coefficient between test and retest. Internal consistency was checked by the Cronbach's alpha coefficient. Construct validity was analyzed comparing FIQ-S with: HAQ, FHAQ, SF-36, SCL90-R, and the visual analogue scale for pain. Sensitivity to change was assessed in an 8-week randomized trial of exercise therapy. Feasibility was analyzed by the time taken in completing the FIQ-S and the proportion of patients able to complete the questionnaire. RESULTS: Translation was concordant. Adaptation affected at 4 sub-items of physical function. One-hundred and two FM patients completed the protocol. Mean age was 48.7 years with a mean of 9.2 years of evolution. Test-retest correlations were between 0.61-0.85 (p < 0.0001). Internal consistency showed alpha = 0.82 for all items and alpha = 0.86 for the sub-items of physical function. Significant correlations (p < 0.0001) were found between the FIQ-S items and HAQ, FHAQ, SF-36 and SCL90-R. For patients treated with the exercise program, the pre-treatment FIQ-S score was 52.0 +/- 11.5 and the post-treatment score was 40.8 +/- 13.7 (p < 0.003). Mean time for completing FIQ-S was 3.3 minutes. In 4% of the patients external help was needed. CONCLUSION: The FIQ-S is a reliable, valid and responsive to changes questionnaire for measuring health status and physical function in Spanish speaking FM patients.

Quality of life of husbands of women with breast cancer.

The life-threatening nature of breast cancer, along with the side effects of treatment, place great strain on patients and their families. Husbands may be especially vulnerable as the main source of support to patients. The present study compared the quality of life (QOL) of husbands of patients with breast cancer (HBC; n=79) to spouses of healthy wives (n=79). Additionally, associations between QOL and caregiver burden, social support, and coping were examined. HBC scored lower on general health, vitality, role-emotional, and mental health subscales of the Medical Outcomes Study (MOS) SF-36 than comparison group participants. No differences were found between groups on the physical functioning, role-physical, bodily pain, or social functioning subscales. Higher QOL in HBC was associated with less caregiver burden as evidenced by lower burden on the Illness Impact Form, lower use of emotion-focused coping on the Ways of Coping Questionnaire, and higher social support on the Interpersonal Support Evaluation List. Wife illness characteristics such as stage of disease and time since diagnosis were not related to QOL in husbands. These findings illuminate the need to support HBC, whose QOL suffers during the breast cancer experience.

Quality of life of living kidney donors: the short-form 36-item health questionnaire survey.

OBJECTIVES: To determine the psychological and social effects of kidney donation on kidney donors by using the short-form 36-item health survey (SF-36) as the quality-of-life questionnaire. METHODS: A total of 104 living donor nephrectomies have been performed at Kobe University Hospital and Nishinomiya Prefectural Hospital. We mailed the questionnaires to donors or handed them out directly at the outpatient clinic. The first part of the questionnaire consisted of the SF-36 (limitations on physical functioning because of health problems) and the second part consisted of 15 questions about donation-related stress, expenses incurred, physical changes, and pre-existing factors such as relationship to the recipients. RESULTS: The SF-36 and the questionnaire about donor satisfaction were completed by 69 donors (48 women and 21 men; mean age 52.1 +/- 8.2 years), only 6 of whom (9%) reported minor complications with the donor operation. The SF-36 scores of our donors were not significantly different from that of the general U.S. population and U.S. donors. In some categories (physical functioning, role-physical, bodily pain, general health, vitality, and mental health), our donors scored slightly higher than the U.S. general population. Although 97% of the donors would make the same choice again, 3% believed that donating had had a negative impact on their health, and 16% reported negative financial consequences. CONCLUSIONS: The quality of life for kidney donors was not affected by donor nephrectomy. Living kidney transplantation seems to be suitable for the rescue of patients with end-stage renal disease. Better psychological and technical preparation for surgery and more consistent follow-up may reduce the negative outcomes even further.

Long-term outcomes after injury in the elderly.

BACKGROUND: The lasting impact of injury on lifestyle in the elderly remains poorly defined. The purpose of this study was to determine the long-term quality-of-life outcomes in elderly trauma patients. METHODS: The trauma registry at a regional trauma center was used to identify hospital survivors of injury > or = 65 years old discharged from April 1996 to March 1999. The 36-Item Short Form (SF-36) Health Survey was administered to this group by telephone interview and the scores compared with age-adjusted Canadian norms. Comparisons with test were made for continuous data. RESULTS: Complete data collection was achieved in 128 of 171 (75%) study patients. The mean Injury Severity Score was 21, the mean initial Glasgow Coma Scale score was 13, and the mean age was 74. Most (97%) were victims of blunt trauma. Compared with Canadian age-adjusted norms, there was a significant (p < 0.05) decrease in seven of eight SF-36 domains: Physical Functioning, Role-Physical and Role-Emotional (limitations secondary to physical and emotional health), Social Functioning, Mental Health, Vitality, and General Health. Before injury, most (98%) were living independently at home. However, at long-term follow-up (mean, 2.8 years; range, 1.5-4.5 years), only 63% were living independently and 20% still required home care. CONCLUSION: Although the majority of elderly injury survivors achieve independent living, long-term follow-up indicates significant residual disability in quality of life as measured by the SF-36.

Health and psychosocial correlates of disordered gambling in older adults.

OBJECTIVE: A number of regional prevalence studies suggest that disordered gambling is a clinically significant problem among older adults. However, little research has evaluated whether older adults with a gambling disorder experience increased health, psychiatric, substance use, and social problems as compared with older adults without a gambling disorder. METHODS: A group of 48 older-adult disordered gamblers and 48 older adult non/infrequent gamblers, matched by age, sex, race, and recruitment site, completed the Addiction Severity Index (ASI), Brief Symptom Inventory (BSI), and Short Form-36 Health Survey (SF-36). Multivariate general-linear models evaluated between-group differences on these indices. RESULTS: Compared with non/infrequent gamblers, disordered gamblers reported increased severity of medical, family/social, psychiatric, and alcohol problems on the ASI. They also scored higher on depression, anxiety, paranoid ideation, and psychoticism subscales of the BSI, and lower on vitality, physical functioning, role-physical, general health, and social functioning subscales of the SF-36. CONCLUSIONS: These results suggest that older adults with a gambling disorder experience increased severity of health and psychosocial problems, compared with older adult non/infrequent gamblers matched by age, sex, race, and recruitment site.

Quantity of dialysis: quality of life--what is the relationship?

Health related quality of life (HRQOL) is increasingly being used to evaluate physical and psychosocial parameters in patients receiving dialysis. In patients with chronic illness, these indices are important adjuncts to biochemical measurements. Inadequate dialysis with low urea clearance (Kt/Vurea) has been linked to adverse outcomes in dialysis patients. Little is known about the relationship between dialysis adequacy and patient reported HRQOL. We evaluated HRQOL in 55 hemodialysis and 60 peritoneal dialysis patients using the RAND 36 Item Health Survey 1.0, measuring the following: physical functioning; role limitations (physical); role limitations (emotional); social functioning; emotional well being; pain; energy; and general health perceptions. Kt/V was also calculated for each patient. Mean HD Kt/V was 1.44 +/- 0.31 (range, 0.5-2.0); mean weekly PD Kt/V was 2.28 +/- 0.90 (range, 1.13-6.02). The relationship between Kt/V and HRQOL was tested using Pearson's correlation. No significant association was found for either treatment group between Kt/V and any of the domains of HRQOL. Thus, HRQOL seems to be influenced by factors other than dialysis adequacy, enhancing its role as an independent measure of patient problems otherwise undetected by traditional objective parameters.

Gender differences in psychosocial profile at entry into cardiac rehabilitation.

PURPOSE: To find out in a sample of coronary patients at entry into a cardiac rehabilitation program, whether women report a lower level of physical functioning and a higher degree of psychosocial impairment than men. METHODS: One hundred and nine male and 122 female patients matched for age with a diagnosis of myocardial infarction, coronary artery bypass grafting, or coronary angioplasty were assessed at entry into a multidisciplinary outpatient rehabilitation program. Information was retrieved from hospital records, a semistructured interview, and several psychological questionnaires. Variables of physical functioning included perceived exercise tolerance, functional complaints, psychosomatic complaints, and sleeping disturbances. Variables of psychosocial impairment included anxiety, depression, vital exhaustion, well-being, feelings of being disabled, displeasure, and social inhibition. RESULTS: At program entry, there were no significant differences in age, coronary risk factors, coronary incident, or medication between genders. However, women reported significantly lower perceived exercise tolerance and significantly more functional and psychosomatic complaints. Moreover, women were significantly more anxious and scored significantly higher on social inhibition and vital exhaustion than men. CONCLUSIONS: At entry into rehabilitation, women in this sample report a higher degree of psychosocial impairment and a lower level of physical functioning than men. Women's significantly higher scores on social inhibition and vital exhaustion might partly explain their reported higher drop-out and lower adherence rates in cardiac rehabilitation.

The elderly: health status benefits and recovery of function one year after coronary artery bypass surgery.

OBJECTIVES: The purpose of this study was to describe the health status (symptoms, function, and quality of life) changes of elderly patients undergoing coronary artery bypass grafting (CABG) and compare these to younger patients. BACKGROUND: Despite increasing use of CABG in the elderly, few data exist about elderly patients' health status benefits from CABG. METHODS: A total of 690 consecutive patients (n = 156, >75 years of age; n = 534, <or=75 years of age) from a single center were administered the Seattle Angina Questionnaire (SAQ) at baseline and at one year. The first 224 patients were also given monthly questionnaires for six months after CABG. RESULTS: Although peri-operative mortality was similar (2.6% vs. 2.2%, p = NS), one-year mortality was greater in older patients (11.5% vs. 5.4%, p = 0.008). Among survivors, similar health status benefits were observed one year after surgery (SAQ change scores for Physical Function 21.5 +/- 27.0 vs. 19.7 +/- 27.0, p = 0.67; Angina Frequency 30.1 +/- 25.7 vs. 24.6 +/- 25.6, p = 0.07; and Quality of Life 37.7 +/- 21.8 vs. 33.6 +/- 25.2, p = 0.16). In 224 patients assessed monthly, elderly patients' physical function scores were significantly lower than the younger group until one year. The age-time interaction term was significant (p = 0.003), confirming a slower recovery of physical function. In contrast, angina relief and quality of life improvement did not differ by age. CONCLUSIONS: Despite a slower rate of physical recovery, older patients derived similar health status benefits from CABG compared with younger patients. These data should assist physicians in counseling elderly patients and suggest that age alone should not be a deterrent for recommending bypass surgery.

An account of consciousness in physical and functional terms: a target for research in the neurosciences.

The neurophysiology of mental events cannot be fully understood unless that of consciousness is understood. As the first step in a top-down approach to that problem, one needs to find an account of consciousness as a property of the biological organism that can be clearly defined as such. However, if it is to deliver what must be expected of it, it should address what is commonly meant by the word consciousness. Unless the last condition is satisfied, the theory will fail to deliver what must ultimately be expected of it. Although current interest lies mainly in the higher functions of consciousness, such as its role in language and social relationships, the common usage of the word relates to modes of awareness that are not denied to creatures lacking language or social relationships. The basic features to be covered include awareness of the surrounding world, of the self, and of one's thoughts and feelings; the subjective qualities of phenomenal experience (qualia); the conditions a brain event must satisfy to enter consciousness; and the main divisions of mental events, such as sensations, feelings, perceptions, desires, volitions, and mental images. In the first four chapters we argue that these basic features of consciousness can all be accounted for in terms of just three categories of internal representations, each supported by the empirical evidence and each accurately definable in physical and functional terms. In the fifth, and last, chapter we take a closer look at two of the categories and what these in particular suggest as the most relevant lines of research in the contemporary spectrum of the neurosciences.

The influence of exercise tolerance on quality of life among patients with heart failure.

The purpose of this study was to explore the influence of exercise tolerance on quality of life (QOL) among patients with heart failure (HF). A descriptive correlational design was used to guide the study. Forty-nine participants who met the selection criteria were enrolled at a medical center in Taipei. Data were collected by using the Short-Form 36 and treadmill tests including an exercise intensity-increasing test and duration-increasing test. The results revealed the mean scores of QOL in terms of physical functioning and mental functioning were 66.99 and 68.82, respectively. The average peak VO2 (exercise intensity tolerance) was 4.65 mets. The average exercise duration tolerances were 768.55, 1717.04 and 1923.48 s for reaching 50% heart rate reserve (HRR), 90% HRR, and completing the whole test, respectively. Patients whose exercise intensity tolerance was > or = 5 mets or whose exercise duration tolerance was > or = 1800 s had better physical functioning, but a significant difference in mental functioning was not observed between the two groups. The findings of the study support the view that exercise testing is safe, feasible, and effective in evaluating exercise tolerance, and that both exercise duration and exercise intensity tolerance were important factors in determining QOL, particularly in physical functioning, for HF patients.

Physical and functional interactions of Galphaq with Rho and its exchange factors.

Recent reports have shown that several heterotrimeric protein-coupled receptors that signal through Galpha(q) can induce Rho-dependent responses, but the pathways that mediate the interaction between Galpha(q) and Rho have not yet been identified. In this report we present evidence that Galpha(q) expressed in COS-7 cells coprecipitates with the Rho guanine nucleotide exchange factor (GEF) Lbc. Furthermore, Galpha(q) expression enhances Rho-dependent responses. Coexpressed Galpha(q) and Lbc have a synergistic effect on the Rho-dependent rounding of 1321N1 astrocytoma cells. In addition, serum response factor-dependent gene expression, as assessed by the SRE.L reporter gene, is synergistically activated by Galpha(q) and Rho GEFs. The synergistic effect of Galpha(q) on this response is inhibited by C3 exoenzyme and requires phospholipase C activation. Surprisingly, expression of Galpha(q), in contrast to that of Galpha(12) and Galpha(13), does not increase the amount of activated Rho. We also observe that Galpha(q) enhances SRE.L stimulation by activated Rho, indicating that the effect of Galpha(q) occurs downstream of Rho activation. Thus, Galpha(q) interacts physically and/or functionally with Rho GEFs; however this does not appear to lead to or result from increased activation of Rho. We suggest that Galpha(q)-generated signals enhance responses downstream of Rho activation.

A physical and functional link between cholesterol and tetraspanins.

By interacting with each others, the tetraspanins are thought to assemble a network of molecular interactions, the tetraspanin web. These tetraspanin/tetraspanin interactions involve in part the palmitoylation of the proteins. We show that tetraspanins interact with cholesterol as indicated by the precipitation of tetraspanin/tetraspanin complexes by digitonin, a cholesterol-precipitating reagent, and the labeling of the tetraspanins CD9, CD81 and CD82 with a photoactivatable cholesterol in vivo. Cholesterol may participate to the interaction of tetraspanins with each other since digitonin-precipitation of tetraspanins was correlated with their mutual interaction, and because these interactions were disrupted following cholesterol depletion by methyl-beta-cyclodextrin (MbetaCD) treatment, or cholesterol sequestration by saponin. A mutant CD9 molecule lacking all palmitoylation sites was not precipitated by digitonin under conditions in which wild-type CD9 was precipitated, indicating a role of palmitoylation for the interaction with cholesterol. Finally, upon ligation of tetraspanins on the surface of a lymphoid B cell line, the tyrosine phosphorylation of several proteins, including the vav nucleotide exchange factor, was inhibited when cells were pretreated with MbetaCD, and increased when they were treated with MbetaCD/cholesterol complexes. Thus, there is a physical and functional link between tetraspanins and cholesterol.

Risk factors for continued illness among Gulf War veterans: a cohort study.

BACKGROUND: There are no prospective cohort studies of prognostic factors on the outcome of Gulf War veterans. We aimed to test the hypotheses that Gulf War veterans who were older; had more severe symptoms; had more exposures during deployment; had increased psychological distress and believed they had 'Gulf War syndrome' would experience greater fatigue and poorer physical functioning at follow-up. METHOD: Gulf War veterans who responded to an earlier retrospective cohort study were followed with a postal survey. More symptomatic individuals were oversampled. Outcome was measured on the Chalder fatigue questionnaire, the General Health Questionnaire and the Medical Outcome Study Short-Form 36. RESULTS: Of those surveyed, 73.8% responded. We found some evidence for four of the five hypotheses. More self-reported exposures at baseline were not associated with poorer outcome, but older people, those with more severe symptoms at baseline, those with psychological distress and who believed they were suffering from 'Gulf War syndrome' had more fatigue at follow-up. Officer status was associated with a better outcome. A similar lack of association was found for exposures and physical functioning and GHQ-12 score. 'Gulf War syndrome' attribution was associated with a worse outcome for GHQ-12 and physical functioning even after controlling for severity of symptoms at baseline. CONCLUSIONS: This study suggests that while multiple vaccination and military exposures are important risk factors for the onset of symptoms in Gulf War veterans, these are not important risk factors for persistence of such symptoms. Instead the severity of the initial symptoms; psychological distress and attributions may be more important determinants of outcome.

Quality of life assessment in advanced non-small-cell lung cancer patients undergoing an accelerated radiotherapy regimen: report of ECOG study 4593. Eastern Cooperative Oncology Group.

PURPOSE: To prospectively evaluate the quality of life (QOL) before, at completion, and after therapy for patients receiving an accelerated fractionation schedule of radiotherapy for advanced, unresectable non-small-cell lung cancer in a Phase II multi-institutional trial. METHODS AND MATERIALS: The Functional Assessment of Cancer Therapy-Lung (FACT-L) patient questionnaire was used to score the QOL in patients enrolled in the Eastern Cooperative Oncology Group Phase II trial (ECOG 4593) of hyperfractionated accelerated radiotherapy in non-small-cell lung cancer. Radiotherapy (total dose 57.6 Gy in 36 fractions) was delivered during 15 days, with three radiation fractions given each treatment day. The protocol was activated in 1993, and 30 patients had accrued by November 1995. The FACT-L questionnaire was administered at study entry (baseline), on the last day of radiotherapy (assessment 2), and 4 weeks after therapy (assessment 3). The FACT-L includes scores for physical, functional, emotional, and social well-being (33 items), and a subscale of lung cancer symptoms (10 additional items). The summation of the physical, functional, and lung cancer symptom subscales (21 items) constitutes the Trial Outcome Index (TOI), considered the most clinically relevant outcome measure in lung cancer treatment trials. RESULTS: The FACT-L completion rates at the designated study time points were as follows: baseline, 30 of 30 (100%); assessment 2, 29 (97%) of 30; and assessment 3, 24 (80%) of 30. At treatment completion, statistically significant declines in QOL scores were noted, compared with baseline for physical and functional well-being. Emotional well-being scores improved at both assessment 2 and assessment 3. The physical and functional scores returned approximately to baseline values at assessment 3. The change in TOI score was evaluated as a function of the clinical response to treatment, toxicity grade, and survival; no clear association was noted. A trend for the largest decrease in QOL was noted for patient groups with shorter survival times. The mean change in the TOI score from baseline to assessment 3 was -8.96 for patients surviving < 52 weeks vs. -0.95 for those surviving > 52 weeks. CONCLUSIONS: The FACT-L questionnaire can be successfully administered to non-small-cell lung cancer patients enrolled in a prospective Phase II trial of accelerated radiation fractionation. The decrement in physical and functional QOL during treatment returned to baseline level at 4 weeks after treatment. Emotional well-being improved at all time points. A trend was noted for shorter survival times in patients with the largest negative change in TOI score. These data suggest that the clinical use of hyperfractionated accelerated radiotherapy did not cause a significant, long-term decrease in the QOL of the treated patients, and that it is feasible to perform a QOL study of patients enrolled in such a trial.

Physical and functional interactions between receptor-like protein-tyrosine phosphatase alpha and p59fyn.

We have examined the in vivo activity of receptor-like protein-tyrosine phosphatase alpha (PTPalpha) toward p59(fyn), a widely expressed Src family kinase. In a coexpression system, PTPalpha effected a dose-dependent tyrosine dephosphorylation and activation of p59(fyn), where maximal dephosphorylation correlated with a 5-fold increase in kinase activity. PTPalpha expression resulted in increased accessibility of the p59(fyn) SH2 domain, consistent with a PTPalpha-mediated dephosphorylation of the regulatory C-terminal tyrosine residue of p59(fyn). No p59(fyn) dephosphorylation was observed with an enzymatically inactive mutant form of PTPalpha or with another receptor-like PTP, CD45. Many enzyme-linked receptors are complexed with their substrates, and we examined whether PTPalpha and p59(fyn) underwent association. Reciprocal immunoprecipitations and assays detected p59(fyn) and an appropriate kinase activity in PTPalpha immunoprecipitates and PTPalpha and PTP activity in p59(fyn) immunoprecipitates. No association between CD45 and p59(fyn) was detected in similar experiments. The PTPalpha-mediated activation of p59(fyn) is not prerequisite for association since wild-type and inactive mutant PTPalpha bound equally well to p59(fyn). Endogenous PTPalpha and p59(fyn) were also found in association in mouse brain. Together, these results demonstrate a physical and functional interaction of PTPalpha and p59(fyn) that may be of importance in PTPalpha-initiated signaling events.

CLINHAQ scale--validation of a Hebrew version in patients with fibromyalgia. Clinical Health Assessment Questionnaire.

Assessment of health status in patients with rheumatic disease, including fibromyalgia (FM), using structured questionnaires has become an important approach to evaluate treatment and outcome. The objectives of this study were to validate a translated version of the Clinical Health Assessment Questionnaire (CLINHAQ) to be used by Hebrew-speaking populations, and specifically to evaluate its usefulness in fibromyalgia syndrome (FM). The CLINHAQ was translated into Hebrew and administered to 90 women with FM along with the Hebrew versions of the Fibromyalgia Impact Questionnaire (FIQ) and the Quality of Life (QOL) Scale. The CLINHAQ includes scales of functional disability, helplessness, anxiety and depression, as well as assessment of current health status and satisfaction with this. All subjects were asked about the presence and severity (assessed by visual analogue scale) of current FM symptoms (pain, fatigue, anxiety etc.); a count of 18 tender points was conducted by thumb palpation, and tenderness thresholds were measured by dolorimetry. Test-retest reliability was assessed by Pearson correlation coefficients, and internal consistency was evaluated with Cronbach's alpha coefficient of reliability. Construct validity was tested by correlating the CLINHAQ items with measures of symptom severity, count of tender point, tenderness thresholds, physical functioning measured by FIQ, and with a score of QOL. Test-retest reliability coefficients ranged from 0.82 to 0.99, and Cronbach's alpha coefficients from 0.725 to 0.929. Significant moderate to high correlations were obtained between most subscales of CLINHAQ and measures of physical functioning, quality of life and severity of FM symptoms. In conclusion, the CLINHAQ is a reliable and valid instrument for measuring health status and physical functioning in Israeli women with FM.
