Chronic upper limb pain: an exploration of the biopsychosocial model

OBJECTIVE: To model pain intensity and consequent disability by independent physical, psychological, and social variables in a group of patients with chronic upper limb pain. METHODS: We studied a group of 73 hospital outpatients with either chronic work related diffuse upper limb pain or carpal tunnel syndrome. We assessed pain intensity, disability, and personality by self-rated questionnaires; and psychiatric morbidity by a standardized interview. We measured illness behavior by assessing coping strategies, illness beliefs, financial benefits, and movements of the most affected limb. RESULTS: In both pain conditions, disability was positively correlated with present pain intensity, depression, helpless coping style, and receipt of state financial benefits; and was negatively correlated with age. This explained 43% of the variance and correctly classified 85% of all patients. Present pain intensity was positively correlated with both depression and the number of arm movements at night. This model explained 15% of the variance and correctly classified 75% of all patients. Inclusion of diagnostic group has no effect on these models. CONCLUSION: The correlations between disability and pain intensity with both psychosocial and physical factors support the biopsychosocial model of disability in particular, and pain to a lesser extent, irrespective of the diagnosis.     

Factors related to sleep disturbance in older adults experiencing knee pain or knee pain with radiographic evidence of knee osteoarthritis

OBJECTIVES: To describe the types and frequencies of sleep complaints and the biopsychosocial factors associated with sleep disturbance in a large community sample of older adults experiencing knee pain or knee pain with radiographic evidence of knee osteoarthritis (OA). DESIGN: Baseline analyses of an observational prospective study. SETTING AND PARTICIPANTS: Participants were 429 men and women aged 65 years and older experiencing knee pain or knee pain with radiographic evidence of OA enrolled in the Observational Arthritis Study in Seniors (OASIS). MEASUREMENTS: Demographic variables (age, gender, ethnicity, education), health (X-rays of knee rated for OA severity, medical conditions, medication use, smoking status, body mass index, self-rated health), physical functioning (self-rated physical functioning, physical performance), knee pain, and psychosocial functioning (social support, depression) were measured. RESULTS: Problems with sleep onset, sleep maintenance, and early morning awakenings occurred at least weekly among 31%, 81%, and 51% of participants, respectively. Bivariate correlates of greater sleep disturbance in those with OA were less education, cardiovascular disease, more arthritic joints, poorer self-rated health, poorer physical functioning, poorer physical performance, knee pain, depression, and less social support. In regression analyses, each set of variables representing the domains of health, physical functioning, pain, and psychosocial functioning contributed to the prediction of sleep disturbance beyond the demographic set. Finally, in a simultaneous model, white race (trend, P = .06), poorer self-rated health, poorer physical functioning, and depressive symptoms were predictive of sleep disturbance. CONCLUSIONS: Sleep disturbance is common in older adults experiencing knee pain or knee pain with radiographic evidence of OA and is best understood through the consideration of demographic, physical health, physical functioning, pain, and psychosocial variables. Interventions that take into account the multidetermined nature of sleep disturbance in knee pain or knee OA are most likely to be successful.     

Symptoms of rhinosinusitis in patients with unexplained chronic fatigue or bodily pain: a pilot study

BACKGROUND: Recent otolaryngologic studies document significant fatigue and bodily pain (BP) in patients with chronic rhinosinusitis. Studies of general medical patients are lacking. METHODS: A case-control study of 297 consecutive general medical outpatients. RESULTS: Sixty-five patients noted unexplained chronic fatigue (UCF), 33 reported BP, and 26 had both. Compared with 232 patients without UCF, patients with UCF more frequently had the following rhinosinusitis symptoms: facial pressure (odds ratio [OR], 9.7; 95% confidence interval [CI], 5.2-18.2), heavy-headedness (OR, 21.9; 95% CI, 10.9-44.0), nasal obstruction (OR, 4.3; 95% CI, 2.3-7.9), frontal headache (OR, 13.6; 95% CI, 6.5-28.5), postnasal drip (OR, 2.8; 95% CI, 1.6-5.0), sore throat (OR, 3.1; 95% CI, 1.5-6.6), and tender cervical lymph nodes (OR, 9.2; 95% CI, 4.3-19.7). A similar predominance of rhinosinusitis symptoms was noted in patients with BP and in 15 patients with UCF who had chronic fatigue syndrome. No increased prevalence of pollen allergy was noted in association with UCF, BP, or chronic fatigue syndrome. Gastrointestinal, sleep, and psychiatric problems were similar between patients with UCF and 38 patients with explained fatigue. Rhinosinusitis symptoms, however, were more common in UCF. CONCLUSIONS: There is an increased prevalence of rhinosinusitis symptoms but not pollen allergy among general medical outpatients with UCF, BP, or both. Rhinosinusitis symptoms are at least as common as gastrointestinal complaints, sleep disturbance, and psychiatric problems (previously well documented complaints associated with UCF and BP). Rhinosinusitis symptoms, furthermore, are more common in UCF than in fatigue explained by a physical or mental illness.     

Depressive symptoms associated with scleroderma

Objective. To examine the prevalence and correlates of depressive symptoms among patients with systemic sclerosis (SSc; scleroderma). Method. Fifty-four outpatients with scleroderma were administered the Beck Depression Inventory, the Neuroticism-Extraversion-Openness Personality Inventory, the Health Assessment Questionnaire, and the Psychosocial Adjustment to Illness Scale. In addition, patients underwent a comprehensive clinical assessment, and pulmonary function tests were obtained. Results. Nearly half of the patients had mild depressive symptoms, and an additional 17% had symptoms in the moderate-to-severe range. Younger patients, those with digital ulceration, and those with more self-rated functional impairment had more depressive symptoms, but there were few other relationships between depressive symptoms and either demographic or physician-rated medical variables. In contrast, there were highly significant relationships between depression and aspects of personality, psychosocial adjustment to illness, and social support. Conclusion. Depressive symptoms in patients with SSc are more strongly related to personality, self-rated disability, and adequacy of emotional support than to objective medical indices of illness severity. Depression in scleroderma is a debilitating comorbid condition that should be recognized and treated in its own right.     

Psychiatric Illness in patients with chronic fatigue and those with rheumatoid arthritis

Objectives:To identify psychiatric differences between patients with chronic fatigue and those with rheumatoid arthritis and to investigate whether patients meeting Centers for Disease Control (CDC) criteria for chronic fatigue syndrome (CFS) can be differentiated from patients with chronic fatigue on measures of disability and psychosocial distress. Design:Cross-sectional study comparing 98 patients with chronic fatigue with 31 patients with rheumatoid arthritis on structured psychiatric interviews and patient questionnaires. Nineteen patients meeting CDC criteria for CFS were compared with 79 patients with chronic fatigue not meeting CDC criteria on questionnaires measuring disability and psychosocial distress. Setting:Consecutive patients with chronic fatigue were selected from a chronic fatigue clinic at the University of Washington, and 31 consecutive patients with rheumatoid arthritis were sampled from a private rheumatology practice. Main results:Patients with chronic fatigue had a significantly higher prevalence of lifetime major depression and somatization disorder than did patients with rheumatoid arthritis. Patients with chronic fatigue also had a significantly higher prevalence of current and lifetime psychiatric diagnoses. Only 19 of 98 patients with chronic fatigue met CDC criteria for CFS. Patients meeting CDC criteria for CFS could not be differentiated from the larger group of patients with chronic fatigue on any study variable. Conclusions:Patients with chronic fatigue have a significantly higher burden of psychiatric illness than do patients with rheumatoid arthritis. The psychiatric illness preceded the development of chronic fatigue in over half the patients. Centers for Disease Control criteria for CFS did not select a subset of chronic fatigue patients who could be differentiated on disability or psychosocial parameters from patients with chronic fatigue who did not meet CDC criteria.

Symptoms and signs in fibromyalgia syndrome

Fibromyalgia syndrome (FM) is a common chronic pain condition that affects at least 2% of the adult population. Chronic widespread pain is the defining feature of FM, but patients may also exhibit a range of other symptoms, including sleep disturbance, fatigue, irritable bowel syndrome, headaches, and mood disorders. The etiology of FM is not completely understood and the syndrome is influenced by factors such as stress, medical illness, and a variety of pain conditions. Establishing diagnosis may be difficult because of the multifaceted nature of the syndrome and overlap with other chronically painful conditions. A unifying hypothesis is that FM results from sensitization of the central nervous system; this new concept could justify the variety of characteristics of the syndrome. FM symptoms can be musculoskeletal, non-musculoskeletal, or a combination of both; and many patients will also experience a host of associated symptoms or conditions. The ACR classification criteria focus only on pain and disregard other important symptoms; but three key features, pain, fatigue and sleep disturbance, are present in virtually every patient with FM. Several other associated syndromes, including circulatory, nervous, digestive, urinary and reproductive systems are probably a part of the so called central sensitivity or sensitization syndrome. A minority subgroup of patients (30-40%) has a significant psychological disturbance. Psychological factors are an important determinant of any type of pain, and psychological comorbidity is frequent in FM. Psychiatric disorders most commonly described are mood disorders, but psychiatric illness is not a necessary factor in the etiopathogenesis of FM.     

Sleep related myoclonus in rheumatic pain modulation disorder (fibrositis syndrome)

Thirty-three patients with rheumatic pain modulation disorder (RPMD) were divided into 2 groups: RPMD with sleep related myoclonus (RPMD-SM) (n = 12) and RPMD only (n = 21). Both groups showed chronic nonarticular musculoskeletal pain, fatigue, tender points, and nonrestorative sleep with alpha (7.5-11 Hz) EEG sleep anomaly. RPMD-SM patients were older, had later onset of illness, showed disrupted sleep with periodic involuntary leg movements that were related to fatigue, and alpha EEG sleep related to fatigue and pain.     

Measuring the epidemiology of distress: the rheumatology distress index

OBJECTIVES: (1) To examine clinical and psychological variables to determine which are associated with psychologic and psychosocial severity or "distress"; (2) to investigate whether patients with the 2 major rheumatic disorders, rheumatoid arthritis (RA) and osteoarthritis (OA), differ in distress variables and distress; and (3) to develop and validate a simple, clinically acceptable index of distress suitable for routine care and research purposes. METHODS: A total of 2,403 patients were evaluated in 2 data sets (N = 1,399 and N = 1,490). The first data set was evaluated in the clinic by a routine clinical examination and administration of the Clinical Health Assessment Questionnaire (CLINHAQ). This instrument includes measures of pain, global severity, functional disability, anxiety, depression, sleep disturbance, fatigue, health satisfaction, and health status. The second data set was evaluated by a mailed questionnaire that included the CLINHAQ, but also coping scales, the Beliefs in Pain Control Questionnaire, the Self Performance Scale, and the Arthritis Helplessness Index. RESULTS: RA and OA groups had similar scores for the variables associated with distress: pain, global severity, functional disability, anxiety, depression, sleep disturbance, fatigue, health satisfaction, and health status. Patients with fibromyalgia (FM) had more abnormal scores for every variable, reflecting overall distress. Using patients with FM as a "gold standard" of distress, we developed an index in data set 2. the Rheumatology Distress Index (RDI), made up of 5 variables, anxiety, depression, global severity, fatigue, and sleep disturbance, that best identified patients with FM compared to other patients. We then validated the instrument on the distress severity clusters formed in data set 1. The correlation between RDI and distress severity cluster was 0.874 with all patients considered and 0.867 with FM patients excluded. In addition, RDI predicted 1,174 of 1,399 (83.9%) cluster memberships correctly. Compared with a battery of psychological and clinical tests that classified 74% of FM and non-FM patients correctly, the RDI and is only slightly less effective, classifying 70.3% correctly. CONCLUSION: Distress is a patient rather than a disease phenomenon. A simple, easy to administer self-report questionnaire can be used to classify patients according to their level of distress. The resulting index, the RDI. accurately identifies distressed and non-distressed patients. Such an index should be useful for patient care and research.     

Sleep disturbances in outpatients with ankylosing spondylitisa questionnaire study with gender implications

OBJECTIVE: To study the sleep pattern in ankylosing spondylitis, and to investigate gender differences in sleep, pain, and fatigue. METHODS: Forty-three male and 27 female patients with ankylosing spondylitis completed a sleep questionnaire and the results were compared with earlier findings in 3,558 persons randomly selected from the general population. RESULTS: Too little sleep was reported by 80.8% of the female and 50.0% of the male patients, compared to 28.8% and 21.8% respectively in the reference group (p<0.0001). The main reason was pain in the pre-sleep and sleep-periods (p<0.0001). Daytime fatigue was a major problem (p<0.0001). Higher correlation was found between pain and daytime fatigue than between sleep disturbance and daytime fatigue. CONCLUSION: Sleep disturbance is a significant problem in ankylosing spondylitis. The disturbance is closely related to pain at bedtime and during the night. Gender differences exist in the subjective sleep disturbance, fatigue, and pain.     

Evaluation and documentation of rheumatoid arthritis disease status in the clinic: which variables best predict change in therapy

To determine in clinical practice which rheumatoid arthritis (RA) clinical status variables are most associated with a change in disease modifying antirheumatic drug (DMARD) therapy, we studied 26,240 observations from 1905 RA patients occurring over 25 years. Variables included tender joint count, erythrocyte sedimentation rate (ESR), grip strength, visual analog scale for pain, global severity, fatigue and sleep, Health Assessment Question functional disability scale (HAQ), anxiety, depression and morning stiffness. Only the tender joint count required a physician. Observations at which a change in DMARD therapy occurred were compared to those where a change did not occur using generalized estimating equations (GEE) and classification and regression tree analysis (CART). Tender joint count, pain, global severity, and ESR were the 4 variables most strongly predictive of DMARD change. CART modeling indicated a special role for fatigue and sleep disturbance in some patients. These data add support in clinical practice for the ACR core set and the DAS set of variables. In addition, they validate the use of these variables in a practice setting. We suggest a minimum set of evaluations comprising: joint count, ESR or CRP, measures of pain and/or severity, a fatigue scale (fatigue being a surrogate for sleep disturbance), and a measure of function such as the HAQ or modified HAQ. Because only joint count requires physician participation, these evaluations are practical for the clinic, and allow quantitative measurement of RA status. With the use of quantile charts, the comparative status of RA and the change in RA status can be determined easily.     

Global sleep satisfaction of older people: the Jerusalem Cohort Study

OBJECTIVES: To describe the nature of global sleep satisfaction (GSS) of older people and the factors associated with it. DESIGN: A 7-year follow-up of an age-homogenous cohort. SETTING: Community based. PARTICIPANTS: Two hundred ninety subjects aged 70 at baseline and 77 at follow-up. MEASUREMENTS: Self-reported sleep domains and a comprehensive assessment of health variables, including psychosocial, physical, and functional factors, at ages 70 and 77. RESULTS: GSS was found to be poor in 25% of subjects at ages 70 and 77, with an estimated average annual remission rate of 7% and an annual incidence of 2.4%. Poor GSS at ages 70 and 77 was significantly associated with difficulty falling asleep, awakening feeling tired, two or more nocturnal awakenings, and taking sleeping tablets. Significant cross-sectional associations were found at age 70 and 77 between poor GSS and poor self-rated health, general fatigue, depression, dependence in one or more activities of daily living, and low level of physical activity. In a regression analysis, risk factors at age 70 for subsequent poor GSS were loneliness, depression, poor self-rated health, economic difficulties, back pain, obesity, and prior poor GSS. The only significant long-term association was between poor GSS and poor self-rated health. GSS did not influence mortality data. CONCLUSION: Poor GSS in older people is common and chronic. Its chief determinants are loneliness, depression, poor self-rated health, economic difficulties, back pain, and obesity. It predicts poor self-rated health but not increased mortality.     

The prevalence and associations of sleep disturbances in patients with systemic lupus erythematosus

The aim of this study was to analyze sleep complaints in patients with systemic lupus erythematosus (SLE) and to determine its prevalence and associations. Fifty outpatients with SLE and an equal number of age- and sex-matched controls were included in the study. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) in both cases and controls. Depressed mood, functional disability and pain severity were assessed in patients using standardized questionnaires. Disease severity, cumulative damage and presence of fibromyalgia were determined by clinical examination. Bivariate associations between sleep quality and disease-related variables as well as demographic variables were calculated. A series of hierarchical regression analyses were computed to determine the independent determinant of sleep quality. PSQI scores were significantly higher in patients with SLE. Prevalence of sleep disturbance was 62%. Functional disability, disease activity and depressed mood correlated positively with sleep disturbances. 36% of the patients satisfied ACR criteria for fibromyalgia. In multiple regression analyses disease activity was found to be an independent determinant of sleep quality. The prevalence of poor sleep quality in patients with SLE was higher than it is generally perceived to be. Functional disability, disease activity and depressed mood contributed significantly to sleep disturbances in SLE.     

Narrative review: the pathophysiology of fibromyalgia

Primary fibromyalgia is a common yet poorly understood syndrome characterized by diffuse chronic pain accompanied by other somatic symptoms, including poor sleep, fatigue, and stiffness, in the absence of disease. Fibromyalgia does not have a distinct cause or pathology. Nevertheless, in the past decade, the study of chronic pain has yielded new insights into the pathophysiology of fibromyalgia and related chronic pain disorders. Accruing evidence shows that patients with fibromyalgia experience pain differently from the general population because of dysfunctional pain processing in the central nervous system. Aberrant pain processing, which can result in chronic pain and associated symptoms, may be the result of several interplaying mechanisms, including central sensitization, blunting of inhibitory pain pathways, alterations in neurotransmitters, and psychiatric comorbid conditions. This review provides an overview of the mechanisms currently thought to be partly responsible for the chronic diffuse pain typical of fibromyalgia.     

Perspectives on posttraumatic fibromyalgia: a random survey of Canadian general practitioners, orthopedists, physiatrists, and rheumatologists

OBJECTIVE: To determine which factors physicians consider important in patients with chronic generalized posttraumatic pain. METHODS: Using physician membership directories, random samples of 287 Canadian general practitioners, 160 orthopedists, 160 physiatrists, and 160 rheumatologists were surveyed. Each subject was mailed a case scenario describing a 45-year-old woman who sustained a whiplash injury and subsequently developed chronic, generalized pain, fatigue, sleep difficulties, and diffuse muscle tenderness. Respondents were asked whether they agreed with a diagnosis of fibromyalgia (FM), and what factors they considered to be important in the development of chronic, generalized posttraumatic pain. RESULTS: More-recent medical school graduates were more likely to agree with the FM diagnosis. Orthopedists (28.8%) were least likely to agree, while rheumatologists (83.0%) were most likely to agree. On multivariate analysis, 5 factors predicted agreement or disagreement with the diagnosis of FM: (1) number of FM cases diagnosed by the respondent per week (p < 0.0001); (2) patient's sex (p < 0.0001); (3) force of initial impact (p = 0.003); (4) patient's pre-collision psychiatric history (p = 0.03); and (5) severity of initial injuries (p = 0.03). The force of initial impact and the patient's pre-collision psychiatric history were both negatively correlated with agreement in diagnosis. Patient related factors (personality, emotional stress, pre-collision physical, mental health) were considered more important than trauma related factors in the development of chronic, widespread pain. CONCLUSION: Future studies of the association between trauma and FM should identify potential cases outside of specialty clinics, and baseline assessments should include some measurement of personality, stress, and pre-collision physical and mental health.     

Alcohol Use and Periodic Limb Movements of Sleep

Alcohol causes significant sleep disturbance but the causes are not well understood. We investigated the relationship between alcohol use and periodic limb movements in a large population of patients at a sleep disorders center. The likelihood of having a clinically significant number of periodic leg movements (more than 20 per hour of sleep) was increased 3-fold in women who consumed two or more alcoholic drinks per day compared with those who did not (25% versus 8%). A similar relation was found among men (22% versus 13%). In addition, women who consumed two or more drinks per day were more likely to report symptoms of restless legs and to be diagnosed with restless legs syndrome. These findings suggest that periodic leg movements contribute to sleep disturbance in a significant proportion of alcohol users. Alcohol use may increase the frequency of periodic leg movements in susceptible individuals. On the other hand, subjects with symptoms related to periodic leg movements may be using alcohol to relieve symptoms, or the movements may be secondary to alcohol-induced sleep disturbance.     

Psychiatric disorders in Ehlers–Danlos syndrome are frequent,diverse and strongly associated with pain

Ehlers–Danlos syndromes (EDS) are a heterogeneous group of hereditary connective tissue disorders characterized by joint hypermobility, widespread musculoskeletal pain and tissue fragility. Psychiatric disorders and psychosocial impairment are common, yet poorly characterized, findings in EDS patients. We investigated the frequency and types of psychiatric disorders and their relationship to systemic manifestations in a cohort of 106 classic and hypermobility type EDS patients. In this retrospective study, extensive medical chart review was performed for patients referred at two genetics clinics who were diagnosed with EDS. Statistical analysis was undertaken to determine the frequency of psychiatric disorders and association with systemic findings. Psychiatric disorders were found in 42.5 % of the EDS cohort, with 22.7 % of patients affected with 2 or more psychiatric diagnoses. Anxiety and depression were most commonly reported, with frequencies of 23.6 and 25.5 %, respectively. A variety of other psychiatric diagnoses were also identified. Abdominal pain [odds ratio (OR) 7.38], neuropathic pain (OR 4.07), migraines (OR 5.21), joint pain (OR 2.85) and fatigue (OR 5.55) were significantly associated with the presence of a psychiatric disorder. The presence of any pain symptom was significantly associated with having a psychiatric disorder (OR 9.68). Muscle pain (OR 2.79), abdominal pain (OR 5.78), neuropathic pain (OR 3.91), migraines (OR 2.63) and fatigue (OR 3.78) were significantly associated with having an anxiety or mood disorder. Joint hypermobility and the classic dermatological features of EDS showed no significant association with having a psychiatric disorder. Our findings demonstrate a high frequency of psychiatric disorders and an association with pain symptoms in EDS.     

The 1microg short Synacthen test in chronic fatigue syndrome

OBJECTIVE: Many studies suggest mild hypocortisolism in chronic fatigue syndrome (CFS), usually assumed to be due to reduced suprahypothalamic drive to the hypothalamo-pituitary-adrenal (HPA) axis. We wished to explore further the state of the HPA axis in CFS using the 1 microg low dose short Synacthen test. DESIGN: Subjects received an intravenous bolus of 1 microg Synacthen; samples for cortisol estimation were taken at baseline and 2, 10, 20, 30, 40 and 60 minutes after injection. PATIENTS: We tested 20 subjects suffering from CFS according to the criteria of the Center for Diseases Control without psychiatric comorbidity and 20 matched healthy controls. All subjects were drug free for at least 1 month. MEASUREMENTS: We calculated the cortisol responses to the test as the maximum cortisol attained, the incremental rise in cortisol over baseline (Deltavalue) and as the integrated area under the curve. RESULTS: There were no significant differences in baseline cortisol or cortisol responses between patients and controls. However, responses generally were low, and many subjects' peak responses were prior to the standard 30 minute sampling time., CONCLUSIONS These results do not lend support to the theory that patients with chronic fatigue syndrome have a low adrenal reserve. However, results from studies assessing the HPA axis are proving to be inconsistent. We suggest that many other factors may be contributing to HPA axis alterations in chronic fatigue syndrome, including sleep disturbance, inactivity, altered circadian rhythmicity, illness chronicity, concomitant medication and comorbid psychiatric disturbance. These sources of heterogeneity need to be considered in future studies, and may explain the inconsistent findings to date.     

Juvenile primary fibromyalgia syndrome

Juvenile primary fibromyalgia syndrome (JPFS) is a common musculoskeletal pain syndrome of unknown etiology characterized by widespread persistent pain, sleep disturbance, fatigue, and the presence of multiple discrete tender points on physical examination. Other associated symptoms include chronic anxiety or tension, chronic headaches, subjective soft tissue swelling, and pain modulated by physical activity, weather, and anxiety or stress. Research and clinical observations suggest that JPFS may have a chronic course that impacts the functional status and psychosocial development of children and adolescents. In addition, several factors have been implicated in the etiology and maintenance of JPFS including genetic and anatomic factors, disordered sleep, psychological distress, and familial and environmental influences. A multidisciplinary approach to treatment of JPFS is advocated, including pharmacologic and nonpharmacologic interventions (eg, psychotherapy, aerobic exercise, sleep hygiene).     

Cognitive-behavioral therapy for sleep abnormalities of chronic pain patients

Chronic pain and insomnia often occur simultaneously, with the vast majority of chronic pain patients complaining of interrupted or poor quality sleep. The need to improve sleep in these patients is clear, given increasing evidence that sleep disturbance is associated with heightened pain sensitivity and elevated disability. This article evaluates the efficacy of pain management programs (PMPs) based on cognitive-behavioral therapy (CBT) principles and CBT for primary insomnia (CBT-I) in treating pain-related insomnia. Although PMPs effectively enhance pain management skills in patients, they do not adequately address insomnia. CBT-I has demonstrated strong efficacy in treating pain-related insomnia, but sleep improvement is not followed by pain reduction. As both CBT approaches involve strengths and limitations, a hybrid form of treatment is needed that simultaneously addresses pain and sleep.     

Physical disability and psychosocial dysfunction in systemic lupus erythematosus

One hundred six ambulatory outpatients with systemic lupus erythematosus (SLE) seen during 1985 completed the Stanford Health Assessment Questionnaire (HAQ) and the Psychosocial Adjustment to Illness Scale (PAIS). Mean HAQ disability, pain and global assessment scores were 0.66, 0.81 and 29.4, respectively, indicating a mild amount of impairment. Significant correlations were observed between increased disability, increased pain and worse global assessment, and poor psychosocial adjustment across all domains of the PAIS. Our data suggest that functional and psychosocial impairment are present in patients with SLE; the use of such measures as outcomes in longitudinal studies is discussed.
