The implications of depression for pain and disability in rheumatoid arthritis

Physician estimate of inflammation vs global assessment in explaining variations in swollen joint counts in rheumatoid arthritis patients

Objective

To analyse patients with RA for inflammatory activity by physician estimate of global assessment (DOCGL) vs an estimate of inflammatory activity (DOCINF) to explain variation in the swollen joint count (SJC).

Methods

Patients with RA were studied at routine care visits. Patients completed a multidimensional health assessment questionnaire (MDHAQ) and the physician completed a 28-joint count for swollen (SJC), tender (TJC) and deformed (DJC) joints and a RheuMetric checklist with a 0-10 DOCGL visual numeric scale (VNS) and 0-10 VNS estimates of inflammation (DOCINF), damage (DOCDAM) and patient distress (DOCSTR). The disease activity score in 28 joints with ESR (DAS28-ESR), Clinical Disease Activity Index (CDAI) and Routine Assessment of Patient Index Data 3 (RAPID3) were calculated. Individual scores and RA indices were compared according to Spearman correlation coefficients and regression analyses.

Results

A total of 104 unselected patients were included, with a median age and disease duration of 54.5 and 5 years, respectively. The median DAS28-ESR was 2.9 (Q1-Q3: 2.0-3.7), indicating low activity. DOCINF was correlated significantly with DOCGL (ρ = 0.775). Both DOCGL and DOCINF were correlated significantly with most other measures; correlations with DOCGL were generally higher than with DOCINF other than for SJC. In regression analyses, DOCINF was more explanatory of variation in SJC than DOCGL and other DAS28-ESR components.

Conclusions

Variation in SJC is explained more by a 0-10 DOCINF VNS than the traditional DOCGL or any other measure in RA patients seen in routine care. DOCINF on a RheuMetric checklist can provide informative quantitative scores concerning inflammatory activity in RA patients monitored over long periods.

Prevalence of depressive symptoms in patients with rheumatoid arthritis at a regional hospital in KwaZulu-Natal, South Africa

Background

Depression affects 14.8% – 38.8% of patients with rheumatoid arthritis (RA) in developed countries. The prevalence and risk factors for depression in patients with RA in sub-Saharan Africa is not well established.

Aim

To determine the prevalence of depressive symptoms in patients with RA.

Setting

Public sector regional hospital in South Africa.

Methods

A cross-sectional descriptive study was undertaken with 110 adult RA patients. A structured socio-demographic and clinical questionnaire, the modified health assessment questionnaire (mHAQ), the simplified disease activity index (SDAI) for RA, the patient health questionnaire (PHQ-9), and the Household Food Insecurity Access scale (HFIAS) for nutritional status, were used. Correlates of depressive symptomatology in participants with RA were identified using t-tests and regression analyses.

Results

Most of the participants were women (90.9%), 67% had moderate to severe RA disease on the SDAI score, 92.7% reported functional disability (HAQ score of ≥ 1), and 87.2% reported mild to severe depressive symptoms. Unemployment (p < 0.01), severe food insecurity (p < 0.01) and functional disability (p = 0.02), were significantly associated with the depressive symptoms, but not with disease activity (p = 0.8) or inflammatory markers (p = 0.63). Unemployment (adjusted β = −5.07, p < 0.01) and severe food insecurity (adjusted β = −4.47, p < 0.01) were significantly associated with depressive symptoms, based on the adjusted regression model.

Conclusion

As RA effects functional status, with the impact of the resulting unemployment and food insecurity being associated with depression, affected people should be screened for depression and managed using a multidisciplinary approach, especially considering the role of social determinants in RA patients with depression.

The broad spectrum of comorbid depression: implications for treatment

There is a high rate of depression in patients with medical or other psychiatric disorders. This comorbid depression is associated with an increased morbidity and mortality from medical illness, poor compliance with treatment, a worsening of somatic symptoms, and often a decrease in functional status. Several recent studies have demonstrated that comorbid depression is highly treatable and that effective treatment often enhances patients' adaptive coping with medical illness. However, when choosing antidepressant therapy, care must be taken to evaluate the patient's illness fully and to avoid potential drug-drug interactions and drug-related illness. This review investigates the use of antidepressants in depressed patients with medical and psychiatric disorders and their effect on prognosis and morbidity, and suggests that there is a place for the use of antidepressant medications in the treatment of comorbid conditions. Generally, the greater safety and tolerability of the selective serotonin reuptake inhibitors provides improved options for the treatment of depression in the medically and psychiatrically ill.

Association of health literacy and sleep problems with mental health of Chinese students in combined junior and senior high school

OBJECTIVES

The aim of this study was to examine the association between health literacy (HL) and sleep problems with mental health of Chinese students in combined junior and senior high school.

METHODS

A cross-sectional study was conducted among seven hundred and seventy-five students from a combined junior and senior high school in Shenyang on December 16, 2016. HL, sleep problems, anxiety symptoms and depressive symptoms were measured by self-reported validated instruments. Multiple logistic regression models were used to examine the association of HL and sleep problems with mental health problems.

RESULTS

The prevalence of anxiety symptoms and depressive symptoms was 24.6% and 45.2%, respectively. Low HL was significantly associated with anxiety symptoms (OR = 2.457, 95%CI: 1.493-4.045) and depressive symptoms (OR = 5.164, 95%CI: 3.233-8.250). Sleep problems were significantly positively correlated with anxiety symptoms (OR = 4.237, 95%CI: 2.831-6.341) and depressive symptoms (OR = 3.170, 95%CI: 2.084-4.823). The students who had sleep problems with low HL had the highest risks of anxiety symptoms (OR = 11.440, 95%CI: 5.564-23.520) and depressive symptoms (OR = 19.470, 95%CI: 8.143-46.558).

CONCLUSION

Our findings suggest that Chinese students in combined junior and senior high school who had sleep problems with low HL are at risk of exhibiting anxiety symptoms and depressive symptoms. Intervention programs of mental health problems should enhance HL level and improve sleep quality.

Psychosocial and demographic factors influencing pain scores of patients with knee osteoarthritis

BACKGROUND

Pain levels in patients with osteoarthritis (OA) of the knee are commonly assessed by using a numeric scoring system, but results may be influenced by factors other than the patient's actual physical discomfort or disease severity, including psychosocial and demographic variables. We examined the possible relation between knee-pain scores and several psychosocial, sociodemographic, disease, and treatment variables in 355 patients with knee OA.

METHODS

The pain-evaluation instrument was a 0- to 10-point rating scale. Data obtained retrospectively from the patients' medical records were demographic characteristics, body mass index (BMI), concomitant disorders, illicit and prescription drug use, alcohol use, smoking, knee OA treatment, and severity of knee OA indicated by Kellgren-Lawrence (KL) radiographic grade. Univariate and multivariate analyses were performed to determine whether these variables correlated with reported pain scores.

RESULTS

On univariate analysis, higher pain scores were significantly associated with Native American or Hispanic ethnicity; a higher BMI; current prescription for an opioid, antidepressant, or gabapentinoid medication; depression; diabetes mellitus; fibromyalgia; illicit drug use; lack of health insurance; smoking; previous knee injection; and recommendation by the clinician that the patient undergo knee surgery. Neither the patient's sex nor the KL grade showed a correlation. On multivariate analysis, depression, current opioid prescription, and Native American or Hispanic ethnicity retained a significant association with higher pain scores.

CONCLUSIONS AND IMPLICATIONS

Our results in a large, ethnically diverse group of patients with knee OA suggest that psychosocial and sociodemographic factors may be important determinants of pain levels reported by patients with knee OA.

The role of catastrophizing in recent onset tinnitus: its nature and association with tinnitus distress and medical utilization

OBJECTIVE

Persistent tinnitus affects 10 to 15% of adults. Little is understood about why only a small percentage of patients become severely affected. Catastrophic thinking has been suggested as one potentially relevant factor that might influence a patient's coping behavior, and thus tinnitus habituation. The current study investigates the concept of tinnitus catastrophizing and its relation with distress and medical utilization in recent onset tinnitus.

DESIGN

Participants were administered a survey assessing catastrophizing, tinnitus distress, medical utilization, coping, and mood disturbance. Regression analyses investigated the nature of tinnitus catastrophizing and its contributions to distress and health care utilization.

STUDY SAMPLE

278 subjects with tinnitus for less than six months were recruited from Ear-Nose-Throat units, through the internet, and newspaper articles.

RESULTS

Controlling for background variables, high subjective tinnitus loudness, low behavioral coping, and depressive symptoms were significantly associated with tinnitus catastrophizing. Furthermore, greater tinnitus catastrophizing was related to higher distress and more frequent medical visits.

CONCLUSIONS

Tinnitus catastrophizing appears to be pivotal already at an early stage of tinnitus experience. Addressing catastrophizing by specific prevention and intervention programs might reduce the development of distress and medical utilization in the long term. Longitudinal studies are required to clarify cause-effect relations.

Can the application of control theory assist patient management in rheumatoid arthritis?

Supporting patient self-management is an important part of the care of patients with rheumatoid arthritis (RA) but patients vary in their capacity and willingness to manage their illness and may feel overwhelmed by the challenge of controlling the impact on their life. This paper discusses the value and importance of control theory and how it might be applied to enhance patients' self-management. Not only does it offer a means of identifying those who might have greatest difficulty in managing their illness, but it also points the way to effective interventions.

SLEEP QUALITY AND IMMUNE FUNCTIONS IN RHEUMATOID ARTHRITIS PATIENTS WITH AND WITHOUT MAJOR DEPRESSION

The purpose of this study was to determine the discriminative factors between rheumatoid arthritis (RA) patients with and without major depression (MD). We assessed subjective sleep quality, pain, and cell-mediated immune functions in RA patients with (n = 20) and without (n = 20) MD by using Pittsburgh Sleep Quality Index (PSQI), visual analogue scale (VAS), and fluorescein isothiocyanat (FITC) labeled CD3, CD4, CD8, CDI9, CD45, CD56, and HLADR T monoclonal antibodies by flow cytometry. We found that the RA patients with MD had significantly higher pain level, poorer sleep equality, higher HDRS points, and higher HLADR T cell level than those without MD; and that these variables are discriminant factors between patient groups. These findings suggest that the RA patients with MD may be differentiated from those without MD by using VAS, PSQI, and HLADR levels; that these variables correctly classify the depressed and non depressed groups up to an accuracy level of 96.8%.

Variability in depression prevalence in early rheumatoid arthritis: a comparison of the CES-D and HAD-D Scales

Background

Depression is common in rheumatoid arthritis (RA), however reported prevalence varies considerably. Two frequently used instruments to identify depression are the Center for Epidemiological Studies Depression (CES-D) scale, and the Hospital Anxiety and Depression Scale (HADS). The objectives of this study were to test if the CES-D and HADS-D (a) satisfy current modern psychometric standards for unidimensional measurement in an early RA sample; (b) measure the same construct (i.e. depression); and (c) identify similar levels of depression.

Methods

Data from the two scales completed by patients with early RA were fitted to the Rasch measurement model to show that (a) each scale satisfies the criteria of fit to the model, including strict unidimensionality; (b) that the scales can be co-calibrated onto a single underlying continuum of depression and to (c) examine the location of the cut points on the underlying continuum as indication of the prevalence of depression.

Results

Ninety-two patients with early RA (62% female; mean age = 56.3, SD = 13.7) gave 141 sets of paired CES-D and HAD-D data. Fit of the data from the CES-D was found to be poor, and the scale had to be reduced to 13 items to satisfy Rasch measurement criteria whereas the HADS-D met model expectations from the outset. The 20 items combined (CES-D13 and HADS-D) satisfied Rasch model expectations. The CES-D gave a much higher prevalence of depression than the HADS-D.

Conclusion

The CES-D in its present form is unsuitable for use in patients with early RA, and needs to be reduced to a 13-item scale. The HADS-D is valid for early RA and the two scales measure the same underlying construct but their cut points lead to different estimates of the level of depression. Revised cut points on the CES-D13 provide comparative prevalence rates.

Depression morbidity in later life: prevalence and correlates in a developing country

OBJECTIVE

To investigate the one-month prevalence of depression morbidity and its association with sociodemographic characteristics, health and functional status, and use of health services in community residents aged 60 years and over in Brazil.

METHODS

This study used a cross-sectional design of face-to-face interviews (N = 7,040) in Rio Grande do Sul State, Brazil. Participants were household residents aged 60 years and older. Measurements included the Short Psychiatric Evaluation Schedule (six-item version) and questionnaire that assessed sociodemographic characteristics, self-reported health status, systemic illnesses, activities of daily living (ADL), use of medical services, and social support.

RESULTS

The overall prevalence of depression morbidity was 22% (men: 18%, women: 25.2%). In controlled analyses, younger age, low income, rural origin, never or no longer married, poor self-rated health, presence of systemic illnesses, visual, hearing, or ADL impairments, hospitalization in the past 12 months, and lack of exercise or employment were significantly associated with depression morbidity, whereas living alone was nearly so associated. Gender, education, minority race, or outpatient visits in the previous six months were not associated with depression morbidity.

CONCLUSION

The overall prevalence of depression morbidity was among the highest previously reported for older persons. In controlled analyses, prevalence declined as age increased, and rates were higher for those with lower income and poorer social, health, and functional status, but did not differ significantly by gender, education, or race/ethnicity. Increased attention should be paid to identifying depression morbidity in those with adverse circumstances and to identifying ameliorating interventions.

Caring for body and soul: the importance of recognizing and managing psychological distress in persons with multimorbidity

Primary care providers routinely encounter patients with interacting physical and psychological conditions that present as undifferentiated symptoms and feelings. Caring for the whole patient requires a good understanding of the interconnection between physical, psychological and social dimensions that may affect patients' well-being. In this article, we review the relationship between psychological distress and multimorbidity through the presentation of clinical vignettes from the real world of primary care, and discuss a team-based approach to managing care for this complex patient population.

Predictors of depression in a sample of 1,021 primary care patients with osteoarthritis

OBJECTIVE

Although there is a strong relationship between depression, chronic pain, and physical activity, there are few findings regarding the prevalence and predictors of depression in patients with osteoarthritis (OA). The goal of the present study was to assess the prevalence and severity of depression in a large sample of patients with OA and to reveal predictors of depression.

METHODS

Patients were approached consecutively in 75 general practices. Of 1,250 distributed questionnaires, 1,021 were returned and analyzed. Besides sociodemographic data, medication and comorbidities, depression, and arthritis were assessed using the Patient Health Questionnaire (PHQ-9) and the Arthritis Impact Measurement Scale. A stepwise multiple linear regression analysis with the PHQ-9 score as the dependent variable was performed.

RESULTS

On the PHQ-9, 19.76% of men and 19.16% of women achieved a score of >or=15, indicating at least a moderately severe depression. Significant sex differences could not be revealed. The strongest predictor for depression severity was perceived pain (beta = 0.243, P < 0.001) and few social contacts (beta = 0.218, P < 0.001). Further predictors were physical limitation of the lower body (beta = 0.157, P < 0.001) and upper body (beta = 0.163, P < 0.001), age (beta = -0.168, P < 0.001), and body mass index (beta = 0.080, P = 0.020).

CONCLUSION

These findings suggest an increased prevalence of depression among patients with OA and emphasize the need for recognition and appropriate treatment. Most of the revealed predictors are influenceable and should be potential targets in a comprehensive treatment of OA to interrupt the vicious circle of pain, physical limitation, and depression.

Serious psychological distress in U.S. adults with arthritis

BACKGROUND

Arthritis and mental health disorders are leading causes of disability commonly seen by health care providers. Several studies demonstrate a higher prevalence of anxiety and depression in persons with arthritis versus those without arthritis.

OBJECTIVES

Determine the national prevalence of serious psychological distress (SPD) and frequent anxiety or depression (FAD) in adults with arthritis, and in adults with arthritis, identify risk factors associated with SPD.

METHODS

Cross-sectional data from the 2002 National Health Interview Survey, an in-person household interview survey, were used to estimate the prevalence of SPD and FAD in adults with (n=6,829) and without (n=20,676) arthritis. In adults with arthritis, the association between SPD and sociodemographic, clinical, and functional factors was evaluated using multivariable logistic regression.

RESULTS

The prevalence of SPD and FAD in adults with arthritis is significantly higher than in adults without arthritis (5.6% vs 1.8% and 26.2% vs 10.7%, P<.001, respectively). In adults with arthritis, SPD was significantly associated with younger age, lower socioeconomic status, divorce/separation, recurrent pain, physical inactivity, having functional or social limitations, and having comorbid medical conditions. Adults aged 18 to 44 years were 6.5 times more likely to report SPD than those 65 years or older, and adults with recurrent pain were 3 times more likely to report SPD than those without recurrent pain.

CONCLUSIONS

Serious psychological distress and FAD affect persons with arthritis and should be addressed in their treatment. Younger adults with arthritis, and those with recurrent pain or either functional or social limitations, may be at higher risk for SPD.

Psychological distress and multimorbidity in primary care

PURPOSE

Psychological distress may decrease adherence to medical treatments and lead to poorer health outcomes of chronic diseases. The aim of this study was to evaluate the relationship between psychological distress and multimorbidity among patients seen in family practice after controlling for potential confounding variables and taking into account the severity of diseases.

METHODS

We evaluated 238 patients to construct quintiles of increasing multimorbidity based on the Cumulative Illness Rating Scale (CIRS), which is a comprehensive multimorbidity index that takes into account disease severity. Patients completed a psychiatric symptom questionnaire as a measurement of their psychological distress. In the first model of logistic regression analyses, we used the counted number of chronic diseases as the independent variable. In subsequent models, we used the quintiles of CIRS.

RESULTS

After adjusting for confounding factors, multimorbidity measured by a simple count of chronic diseases was not related to psychological distress (OR, 1.12; 95% CI, 0.97-1.29; P = .188), whereas multimorbidity measured by the CIRS remained significantly associated (OR, 1.67; 95% CI, 1.19-2.37; P = .002). The estimate risk of psychological distress by quintile of CIRS was as follows: Q1/2 = 1.0; Q3 = OR, 1.72; 95% CI, 0.53-5.86; Q4 = OR, 2.99; 95% CI, 1.01-9.74; Q5 = OR, 4.67; 95% CI, 1.61-15.16.

CONCLUSIONS

Psychological distress increased with multimorbidity when we accounted for disease severity. Clinicians should be aware of the possible presence of psychological distress, which can further complicate the comprehensive management of these complex patients.

Coping with rheumatoid arthritis pain in daily life: within-person analyses reveal hidden vulnerability for the formerly depressed

This study examined the association between history of depression and day-to-day coping with rheumatoid arthritis (RA) pain. The sample was 188 RA-diagnosed participants, 73 of whom were identified by a structured clinical interview as having a history of major depression. None had current major depression. All participated in a 30-day prospective study in which they made end-of-day ratings of their arthritis pain, the strategies for how they coped with their pain, their appraisals of daily pain, and daily mood. Hierarchical linear models evaluated whether individuals with and without depression history differed in their average pain and the other daily measures; and separately, whether they differed in their within-person associations between pain and the daily measures (e.g., the day-to-day contingency between pain and mood). All analyses controlled for current mild depressive symptoms, neuroticism, and age. Previously depressed individuals were indistinguishable from their never depressed peers in their average pain and the other daily measures; however, the previously depressed exhibited significantly stronger associations between pain and several aspects of their daily emotional experience, suggesting more pain-contingent well-being. For individuals with a history of depression, increases in daily pain corresponded with more frequent efforts to cope with their pain by venting their emotions, significantly stronger impairments in mood, and, if they were also presently distressed, reduced perceptions of control over their pain, compared to the never depressed. Patterns suggest that formerly depressed individuals exhibit a hidden vulnerability in how they manage chronic pain. This vulnerability is best revealed by a daily process approach.

Paroxetine for somatic pain associated with physical illness: a review

OBJECTIVE

The purpose of this article is to review the prevalence of somatic pain with and without depression or anxiety and the pharmacologic effects of the selective serotonin reuptake inhibitor paroxetine on pain in physical conditions with and without comorbid depression or anxiety.

DATA SOURCES

MEDLINE and PsychLIT/PsycINFO database. Keywords included depression, anxiety, pain, somatic, antidepressants, and paroxetine. Only English-language publications and abstracts were considered.

STUDY SELECTION

More than 100 articles that reflected the prevalence of somatic pain in patients with physical illness with and without comorbid depression or anxiety and that evaluated the efficacy of antidepressants in this population were identified and reviewed.

DATA SYNTHESIS

Nearly two thirds of patients with major depressive disorder suffer from a physical illness, and about one fifth of patients with chronic physical illness are depressed. Both of these comorbidities pose diagnostic and therapeutic challenges. Therapeutic effects of antidepressants on pain improvement in patients with chronic physical illnesses and comorbid depression/anxiety have been attributed to the antidepressant or anxiolytic properties of these drugs. However, tricyclic antidepressants have demonstrated analgesic properties in patients with physical illness both with and without depression. The review looks at evidence for the efficacy of the selective serotonin reuptake inhibitor paroxetine on pain in physical illness with and without depression and the mechanisms for the relief of pain and depression.

CONCLUSIONS

The efficacy of paroxetine for depression and anxiety comorbid with physical illness looks promising. Studies also allude to evidence linking the analgesic properties of paroxetine with its serotonergic and noradrenergic activity. Large randomized controlled trials within specific antidepressant classes and also comparing dualaction antidepressants are warranted that could shed some light on the unique advantage of paroxetine over other antidepressants.

Psychological distress and personality traits in early rheumatoid arthritis: a preliminary survey

OBJECTIVES

To investigate psychiatric manifestations, personality traits, and ego mechanisms of defense involved in early rheumatoid arthritis (RA).

METHODS

Twenty-two unselected early RA outpatients with disease duration less than 1 year participated in the study. The majority of participants were females (72.7%), married (81.8%), aged 51.0+/-14.6 years. Thirty-four subjects matched for age, sex and educational level served as "healthy" controls. General Heath Questionnaire, Symptom Distress Checklist, Defense Style Questionnaire and Hostility and Direction of Hostility Questionnaire were used; disease activity was estimated by disease activity for 28-joint indices score.

RESULTS

Seven patients (31.8%) presented psychological distress scores indicative of possible psychiatric caseness, expressing obsessive-compulsive symptoms and depression, as compared to six (17.6%) of controls. Social dysfunction distress and somatization were prominent psychiatric manifestations in early RA group. Early RA patients tend to adopt a less adaptive defense style than controls. Although disease activity was not correlated to psychological distress, a significant association between disease activity and patients' defensive style was observed: as the disease is exacerbated, there was a shift from "non-adaptive" to "immature image distorting or borderline" defense style, suggesting a rather fragile underlying personality structure.

CONCLUSION

Psychological distress is a relatively common experience in early RA. Social dysfunction, along with the less adaptive defense style, which under the stress of the disease exacerbation turns to "borderline", underlines the importance of a careful assessment and consultation in early RA patients in order to face the distress shortly after diagnosis and highlights potential risk factors for future adaptation to exacerbations of the disease.

Severity of chronic pain and its relationship to quality of life in multiple sclerosis

INTRODUCTION

This study used reliable and validated instruments to compare pain severity in multiple sclerosis (MS) to that in other chronic painful conditions, and to examine relationships between chronic pain in MS and health-related quality of life (HRQOL).

METHODS

Ninety-nine MS patients completed a self-administered survey comprised of the Medical Outcomes 36-Item Short-Form Health Survey, the Short-Form McGill Pain Questionnaire, and the Hospital Anxiety and Depression Scale.

RESULTS

Pain severity was not different between MS patients with pain and rheumatoid arthritis (P = 0.77) or osteoarthritis (P = 0.98) patients. Chronic pain in MS was less often neurogenic than non-neurogenic, although severity of neurogenic pain was greater than that of non-neurogenic pain (P = 0.048). Chronic pain in MS was found to have no significant relationship to age, disease duration or disease course. Instead, we found that pain was correlated with aspects of HRQOL, particularly mental health (r = 0.44, P < 0.0001) versus physical functioning (r = 0.19, P > 0.05). Chronic pain was significantly related to anxiety and depression for females but not for males with MS.

CONCLUSIONS

Chronic pain in MS is as severe as pain in arthritic conditions and is associated with reduced HRQOL. Thus, pain can be a significant symptom for MS patients and the need for treatment may be underestimated.

The longitudinal occurrence and impact of comorbid chronic pain and chronic depression over two years in continuing care retirement community residents

OBJECTIVE

To describe the longitudinal course of depressive symptoms and pain experienced by continuing care retirement community (CCRC) residents and to investigate the impact of comorbid chronic activity-limiting pain and chronic high depressive symptoms on physical functioning and health service use.

METHODS

This longitudinal study of 169 CCRC residents involved five assessments (baseline and four in-person interviews at 6-month intervals). The Geriatric Depression Scale (GDS), questions drawn from the McGill Pain Questionnaire, and self-report data on physical functioning and health care use were assessed. Individuals reporting activity-limiting pain and those with GDS scores > or =11 at three or more assessments were considered to have chronic pain or chronic depression, respectively. The analysis sample included 169 CCRC residents. Multivariate logistic regression was used to test hypotheses.

RESULTS

Pain and depressive symptoms were characterized by longitudinal stability. Of the sample, 37% met the criteria for chronic activity-limiting pain, 21% met the criteria for chronic high depressive symptoms, and 13% were comorbid. Adjusting for age and health conditions, those with chronic activity-limiting pain were five times more likely than those in the lowest pain group to persistently be in the worst two quartiles of physical functioning, as were those with even one GDS score >5. The odds of poor physical functioning were 11.2 times greater in those with comorbid chronic pain and depression. Comparable greater odds were seen in this sample for frequency of medical care visits (adjusted odds ratio AOR]=12.4) and consistently high use of all medical services (AOR=3.5).

CONCLUSIONS

Pain and depressive symptoms were both common and appeared remarkably stable over time. Depressive symptoms contributed significantly to the prediction of impairment associated with pain, and identification and treatment of such symptoms, even minor symptoms, could reduce pain-related impairment and health care costs in the elderly.

Frequent mental distress status among adults with arthritis age 45 years and older, 2001

OBJECTIVE

To identify characteristics and behaviors among persons with arthritis through evaluation of self-perceived mental health status.

METHODS

Data were analyzed for adults with arthritis age 45 years or older from the 2001 Behavioral Risk Factor Surveillance System, an ongoing, state-based, random-digit-dialed telephone survey of noninstitutionalized adults living in the United States.

RESULTS

The prevalence of frequent mental distress (FMD; > or =14 self-reported mentally unhealthy days in the past 30 days) among persons with arthritis was 13.4%. Among persons with arthritis, those with FMD as compared with those without FMD were more likely to be underweight and obese than normal weight; they also were more likely to be insufficiently active or inactive than following recommended physical activity guidelines. In addition, those with arthritis and FMD were more likely to report disability and impaired physical and general health than were those with arthritis but without FMD.

CONCLUSION

Physicians should encourage their patients with arthritis and mental distress to participate in educational and behavioral interventions shown to have both physical and psychological benefits.

Clinical skills: evidence-based nursing care of people with rheumatoid arthritis

Rheumatoid arthritis is a complex inflammatory disease with an unknown cause, uncertain prognosis and no known cure. The physical symptoms of this chronic disease can impact on the patient's psychological state and also affect the family unit and social/economic viability. Nursing patients with such a multifaceted illness is a skilled and complex task and it is imperative that the care provided is optimal, timely and underpinned by patient education. Evidence-based nursing care founded on an in-depth knowledge of the disease and its treatments will help to achieve optimal patient outcome.

Management of depression in rheumatoid arthritis: A combined pharmacologic and cognitive-behavioral approach

OBJECTIVE

To examine the effectiveness of cognitive-behavioral and pharmacologic treatment of depression in rheumatoid arthritis (RA).

METHODS

Subjects (n = 54) with confirmed diagnoses of both major depression and RA were randomly assigned to 1 of 3 groups: 1) cognitive-behavioral/pharmacologic group (CB-PHARM), 2) attention-control/pharmacologic group, or 3) pharmacologic control group. Measures of depression, psychosocial status, health status, pain, and disease activity were collected at baseline, posttreatment (10 weeks), 6-month followup, and 15-month followup. Data were analyzed to compare the treatment effectiveness of the groups; data also were aggregated to examine the effects of antidepressive medication over time. Lastly, a no-treatment control group was defined from a cohort of persons who declined participation.

RESULTS

Baseline comparisons on demographic and dependent measures revealed a need to assess covariates on age and education; baseline scores on dependent measures also were entered as covariates. Analyses of covariance revealed no statistically significant group differences at postintervention, 6-month followup, or 15-month followup, except higher state and trait anxiety scores for the CB-PHARM group at the 15-month followup. In the longitudinal analyses of the effects of antidepressive medication, significant improvement in psychological status and health status were found at posttreatment, 6-month followup, and 15-month followup, but no significant improvements were shown for pain or disease activity. In addition, the comparison of the aggregated pharmacologic group with a no-treatment group revealed a statistically significant benefit for the 3 groups that received the antidepressive medication.

CONCLUSION

In persons with RA, cognitive-behavioral approaches to the management of depression were not found to be additive to antidepressant medication alone, but antidepressant intervention was superior to no treatment.

Assessment of depression in rheumatoid arthritis: a modified version of the center for epidemiologic studies depression scale

OBJECTIVE

The Center for Epidemiologic Studies Depression Scale (CES-D) is an instrument commonly used to assess depressive symptoms. Although the psychometric properties of the instrument are well established, the instrument's ability to identify confirmed cases of major depression has been unclear. The purpose of this study was to evaluate the ability of cutoff scores from both a full scale and a modified CES-D to detect major depression in people with rheumatoid arthritis (RA).

METHOD

Data were analyzed from 457 persons with RA, including 91 who met criteria for major depression.

RESULTS

Results indicated that, in general, a full scale cutoff score of 19 was the most efficient in identifying cases of major depression; the cutoff score of 19 outperformed a variety of other cutoff scores from the modified scale. Even the most efficient cutoff scores, however, demonstrated problems in accurately identifying people with depression.

CONCLUSION

The CES-D, while potentially useful as a screening tool, should not be used to identify cases of major depression.

Testing a theory of chronic pain

BACKGROUND

Chronic pain is highly prevalent among older people with arthritis, with depression as its major outcome. The psychopathological process of chronic pain and its outcomes in older people with arthritis have not been the subject of extensive research. The purpose of this study was to test a middle-range theory of chronic pain derived from the Roy Adaptation Model, a nursing theory whose validity has not been tested in the context of chronic pain.

METHODS

The study used a convenience sample of 71 older people with arthritis. Two subscales of the Arthritis Impact Measurement Scales were used to measure pain and physical disability. Social support was measured by Part II of the Personal Resource Questionnaire, and the Elderly Daily Stress scale was used to measure daily stress. Participants also completed the 10-item Center for Epidemiological Studies of Depression scale. Univariate analysis, correlation, and path analysis were used to analyse the data.

RESULTS

Overall, the data supported the hypothesized model in which pain, disability, social support, age, and gender are predictors of daily stress and daily stress further predicts depression. The direct effects of chronic pain, disability, and social support accounted for 37% of the variance of daily stress, which in turn predicted 35% of the variance of depression. Age and gender had no influence on daily stress. The chi-square index suggested a fit between the data and the model, and therefore the current model is temporarily accepted. Other fit indices also showed a good fit of the model to the data. To simplify the model, a revised version was developed.

CONCLUSIONS

This study validated a middle-range theory to explain the effects of chronic pain in older people with arthritis and highlights the importance of chronic pain in the development of depression.

A comparison of self-reports of distress and affective disorder diagnoses in rheumatoid arthritis: a receiver operator characteristic analysis

OBJECTIVE

To compare 3 commonly used psychiatric symptom checklists (the Center for Epidemiological Studies Depression Scale [CES-D], the Positive and Negative Affect Schedule, and the Endler Multidimensional Anxiety Scales [EMAS]) to determine their sensitivity, specificity, and ability to discriminate between a disorder (Major Depression [MD], Generalized Anxiety Disorder [GAD]), and no disorder. To compare the checklists for their ability to discriminate between type of disorder (MD and GAD). To evaluate the discriminant ability of the subscales, particularly positive affect; whether the somatic items in the CES-D artificially inflate affective scores; and the optimal cut off score for the CES-D.

METHODS

We compared the 3 scales to diagnostic criterion of MD, GAD, and comorbid disorder using receiver operator characteristic (ROC) and logistic regression analyses. The sample consisted of a national panel of 415 individuals with rheumatoid arthritis (RA).

RESULTS

Each of the scales had high sensitivity and specificity (areas under the curve: CES-D = 0.92, negative affect = 0.88, positive affect and EMAS = 0.82). The CES-D, however, demonstrated better sensitivity and specificity than the positive affect and the EMAS, but not the negative affect scale.

CONCLUSION

All 3 self-reports have high combined sensitivity and specificity as measures of affective disorders among RA patients.

The relationship between cognitive appraisal, affect, and catastrophizing in patients with chronic pain

A study was conducted to clarify the nature of catastrophizing, a construct that is frequently referred to in the chronic pain literature. Information regarding 3 affective experience and 3 affect regulation dimensions was gathered from a heterogeneous sample of 104 chronic pain patients by using a semistructured clinical interview and the Affect Regulation and Experience Q-Sort (AREQ). Self-report questionnaires included visual analog pain scales, the Coping Strategies Questionnaire (CSQ), Multidimensional Pain Inventory (MPI), McGill Pain Questionnaire (MPQ), and Center for Epidemiological Studies Depression scale (CES-D). Hierarchical multiple regression was used to demonstrate the relative contributions of affective and cognitive appraisal components of catastrophizing. Thirty-one percent of the variance in CSQ-Catastrophizing scores was explained by a combination of cognitive appraisal variables (perceived ability to control pain; MPI Life Control) and AREQ scores, even after adjusting for pain severity and chronicity, age, and sex of participants. Results of the study strongly suggest that, rather than thinking of catastrophizing primarily as a cognitive coping construct, it should be described as an elaborate construct made up of both cognitive appraisal and affective components. Implications for tailoring interventions to match individual styles of affect regulation are discussed.

Tailored cognitive-behavioral therapy in early rheumatoid arthritis for patients at risk: a randomized controlled trial

Recent developments in chronic pain research suggest that effectiveness of cognitive-behavioral therapy (CBT) may be optimized when applying early, customized treatments to patients at risk. For this purpose, a randomized, controlled trial with tailor-made treatment modules was conducted among patients with relatively early rheumatoid arthritis (RA disease duration of <8 years), who had been screened for psychosocial risk profiles. All participants received standard medical care from a rheumatologist and rheumatology nurse consultant. Patients in the CBT condition additionally received an individual CBT treatment with two out of four possible treatment modules. Choice of treatment modules was determined on the basis of patient priorities, which resulted in most frequent application of the fatigue module, followed by the negative mood, social relationships and pain and functional disability modules. Analyses of completers and of intention-to-treat revealed beneficial effects of CBT on physical, psychological and social functioning. Specifically, fatigue and depression were significantly reduced at post-treatment and at the 6-month follow-up in the CBT condition in comparison to the control condition, while perceived support increased at follow-up assessment. In addition, helplessness decreased at post-treatment and follow-up assessment, active coping with stress increased at post-treatment, and compliance with medication increased at follow-up assessment in the CBT condition in comparison to the control condition. Results indicate the effectiveness of tailor-made CBT for patients at risk in relatively early RA, and supply preliminary support for the idea that customizing treatments to patient characteristics may be a way to optimize CBT effectiveness in RA patients.

Recent advances and future directions in the biopsychosocial assessment and treatment of arthritis

This article provides an overview of the emerging literature on biopsychosocial assessment and treatment for two of the most common forms of arthritis: osteoarthritis and rheumatoid arthritis. The article is divided into 3 parts. In the 1st part, the basic elements of the biopsychosocial approach to assessing and treating persons having arthritis is described. In the 2nd part, the authors evaluate studies of biopsychosocial approaches to the assessment of arthritis pain and disability. Six research areas are reviewed: learned helplessness, depression, stress, pain coping, self-efficacy, and the social context of arthritis. The 3rd part of the article reviews studies that testing the efficacy of biopsychosocial treatment approaches for persons having osteoarthritis and rheumatoid arthritis.

Depression in rheumatoid arthritis: a systematic review of the literature with meta-analysis

OBJECTIVE

This systematic review and meta-analysis examined the strength of association between rheumatoid arthritis and depression. In addition, we investigated the extent to which sociodemographic characteristics, level of pain, and method of assessing depression might affect the degree of depression.

METHODS

CD-ROM databases and bibliographies were searched to identify all studies comparing depression in patients with rheumatoid arthritis and control subjects using standardized assessments. Effect sizes (Pearson's r) and probabilities were combined across studies. We examined the extent to which the association between rheumatoid arthritis and depression could be attributed to level of pain (using contrasts), sociodemographic differences between groups (combining methodologically restricted studies), and methods of assessing depression (examining heterogeneity across studies).

RESULTS

Twelve independent studies comparing depression in patients with rheumatoid arthritis with depression in healthy control subjects were found. Effect sizes for depression were small to moderate (r =.21, p <.0001; heterogeneous). This effect was not reduced in studies controlling for sociodemographic characteristics (r =.27, p <.0001). The effect sizes did vary in a linear manner in proportion to the effect size for pain (z = 2.67, p =.0064). The effect sizes produced by different measures of depression were heterogeneous (chi(2) for Fisher's Z = 24.6, p =.0002), with the Hospital Anxiety and Depression Scale giving effect sizes most dissimilar to those of other measures.

CONCLUSIONS

Depression is more common in patients with rheumatoid arthritis than in healthy individuals. This difference is not due to sociodemographic differences between groups, but it may be attributable, in part, to the levels of pain experienced. Variation in the methods of assessing depression partly accounts for the differences among studies examining the levels of depression in patients with rheumatoid arthritis.

The Effects of Pain and Depression on Physical Functioning in Elderly Residents of a Continuing Care Retirement Community

OBJECTIVE. Explore the relationships between pain, depression, and functional disability in elderly persons.

DESIGN

A cross-sectional, observational study of 228 independently living retirement community residents.

METHODS

Self-report measures of pain (adaptation of McGill Pain Questionnaire), depression (Geriatric Depression Scale [GDS]) and physical functioning (Physical performance difficulties, activities of daily living [ADL], independent activities of daily living [IADL], and 3-meter walking speed) were employed.

OUTCOME MEASURES

Physical functioning variables were dichotomized. Individuals in the lowest quartiles of functional performance and of walking speed were contrasted to all others; for ADL and IADL, those needing some help were compared with those independent in activities.

RESULTS

Pain and depression levels were strongly related to physical performance; depression levels were related to ADL and walking speed. In multivariate analyses, an interaction effect was observed where the effects of pain were a function of level of depression. Individuals reporting activity-limiting pain and slightly elevated depressive symptom levels, sub-threshold depression, or major depression were significantly more likely (AOR 7.8; 95% CI, 3.07-20.03) than non-depressed persons to be in the lowest quartile of self-reported physical performance.

CONCLUSIONS

While both pain and depression level affect physical performance, depressive symptoms rather than pain appear the more influential factor. When seeing elderly patients, identifying, evaluating, and treating both pain complaints and depressive symptoms and disorders may reduce functional impairment.

The impact of passive coping on rheumatoid arthritis pain

OBJECTIVE

To determine the ability of coping to predict pain.

METHODS

Data on 111 rheumatoid arthritis (RA) patients (86 women and 25 men) were gathered from a mail survey. Statistical analyses were conducted on a range of clinical and psychological variables: physical disability, disease duration, pain, depression, helplessness, and passive and active coping. Pain was measured with both the pain subscale of the Arthritis Impact Measurement Scales and a visual analogue scale, and coping was measured with the Vanderbilt Pain Management Inventory.

RESULTS

A series of multiple regression analyses revealed that the optimal predictors of pain in RA were physical disability and passive coping, which accounted for 40% of the variance associated with pain. Path analysis revealed that passive coping mediates between the physical disability and pain, and between physical disability and depression.

CONCLUSION

The results of this study have implications for the overall management of RA. In addition to the medical treatment, the experience of pain and depression in RA should be addressed through an intervention programme designed to enhance coping strategies.

Cognitive-behavioral treatment in unselected rheumatoid arthritis outpatients

OBJECTIVE

This trial was performed to evaluate the efficacy of an adjunctive cognitive-behavioral treatment compared with rheumatological treatment alone in unselected rheumatoid arthritis outpatients.

DESIGN

A prospective randomized control design was used. Change in medication during treatment was controlled by matching therapy- and control-group subjects according to this change in medication, sex, age, duration of disease, and functional class.

SETTING

A rheumatological outpatient clinic, University of Goettingen, Germany.

PATIENTS

Fifty-five consecutive outpatients with a diagnosis of rheumatoid arthritis (age 52.7 years, 74.5% female, duration of disease 9.4 years) finished the study.

INTERVENTIONS

Subjects received routine care by the rheumatologists and routine medical treatment. Cognitive-behavioral treatment subjects (n = 19) received adjunctive standardized cognitive-behavioral group treatment with 12 weekly sessions.

OUTCOME MEASURES

Outcome measures included disease activity variables, pain variables (pain intensity, affective pain), psychological symptoms, and coping.

RESULTS

Subjects mostly demonstrated an increasing disease activity during treatment; change in medication during treatment was necessary in some patients. In the cognitive-behavioral treatment group the course of rheumatoid arthritis seemed less progressive than in the control group. The core effects of cognitive-behavioral treatment pertain more to improved coping, emotional stabilization, and reduced impairment than to reduced pain intensity. Passive, emotion-focused coping, helplessness, depression, anxiety, affective pain, and fluctuation of pain are reduced, "Acceptance of Illness" is improved.

CONCLUSIONS

Cognitive-behavioral therapy has proven an effective adjunct to standard treatment of rheumatoid arthritis outpatients. These effects were shown in an unselected sample with increasing disease activity and with comparable changes in medication during treatment. We recommend cognitive-behavioral treatment as an desirable adjunct to standard medical treatment of rheumatoid arthritis.

The meeting of pain and depression: comorbidity in women

The higher prevalence of depression in women is coupled with a higher prevalence of pain complaints. Growing evidence suggests that the comorbidity of these conditions is also proportionately higher in women than men. This paper critically reviews the empirical findings relating to gender differences in comorbid pain and depression as well as findings in support of hypothesized etiologic factors that could explain why women may be more susceptible than men to comorbidity. The empirical evidence for biogenic, psychogenic, and sociogenic explanatory models is presented, and an integration of these models is proposed as a guideline to both research and clinical practice. In conclusion, it is argued that gender-differentiated treatment strategies are not clinically indicated at this time.

Rheumatoid arthritis: current clinical and research directions

Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by synovitis and joint erosions. It affects approximately 1% of the adult population in a female/male ratio ranging from 2:1 to 4:1. RA is an insidious disease, typically having an onset of symmetric joint swelling and reaching a peak incidence in the fourth and fifth decades. Extraarticular manifestations include pulmonary, ocular, and vascular disease. The etiology of RA remains unknown. Attempts to discover infectious causes have proven unsuccessful, although environmental influences may trigger a response leading to the development of this autoimmune disease. Genetic associations have been identified, particularly with the major histocompatibility complex class II antigens. Furthermore, twin studies have shown a 30%-50% concordance rate for monozygotic twins. Approximately 70%-80% of patients with RA have rheumatoid factor present in the blood, although its role remains unclear. Hormonal status may influence RA. The majority of RA patients are women, and in 75% of them, the disease improves during pregnancy. RA has significant financial and social implications associated with treatment costs, lost wages, disability, and increased mortality. Mainstays of medical therapy have included nonsteroidal anti-inflammatory and immunosuppressive agents, such as prednisone and methotrexate. Recent advances in the treatment of RA include specific inhibitors of cyclooxygenase II, T cells, blood vessels, cytokines (such as tumor necrosis factor-alpha [TNF-alpha] or interleukin-1 [IL-1]), and adhesion molecules. Additional studies are ongoing with combination interventions. It is anticipated that a better understanding of the basic pathophysiologic mechanisms critical in RA pathogenesis will provide more precise and efficacious therapy.
