Abstract
BACKGROUND: Strategies to reduce osteoarthritis (OA) symptoms and increase physical function in persons with lower extremity (LE) OA is a public health priority. OBJECTIVE: To examine associations between diet quality and measures of physical function among overweight and obese older adults with self-reported LE OA. METHODS: 413 overweight and obese primarily African American adults ≥60 years old with LE OA were assessed. Diet quality was quantified using the Healthy Eating Index-2010 (HEI-2010) and Alternative Healthy Eating Index-2010 (AHEI-2010). The six-minute walk, 30-second chair-stands, and timed up-and-go tests were used to assess physical function. Unadjusted and multivariable linear regressions were performed to assess associations between the diet quality and measures of physical function. RESULTS: The mean age of the subjects was 67.8 (SD 5.9) years and mean BMI was 34.8 (SD 5.5) kg/m2. Adjusting for total calories, AHEI-2010 total score was associated with superior performance on the six-minute walk test. However, the association was attenuated when also controlling for age, gender, BMI, waist circumference, self-reported pain, and physical activity. HEI-2010 was not associated with the physical function measures. CONCLUSION: AHEI-2010 total score was positively associated with walking speed among older overweight and obese primarily AA older adults with LE OA. However, the association weakened when adjusting for subject covariates. The relationship between diet quality and physical function among health disparate populations should be further investigated in larger cohorts and using rigorous experimental study design.

[PMID: 33022324 PMCID: PMC7704684 DOI: 10.1016/j.ypmed.2020.106267] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2020] [Revised: 07/29/2020] [Accepted: 09/01/2020] [Indexed: 11/30/2022]
Abstract
This comparative effectiveness trial compared the longer-term effectiveness (12 and 18 months) of the standard Fit & Strong! physical activity program to Fit & Strong! Plus, which combined physical activity and dietary weight loss. Outcomes were weight, diet quality, physical activity, osteoarthritis symptoms, performance measures, and anxiety/depression. In this study, 413 overweight/obese participants with OA, ≥60 years old and primarily African American, were randomly assigned to Fit & Strong! (F&S!) or Fit & Strong! Plus (F&S! Plus), with outcomes assessed at 2, 6, 12, and 18 months. 356 (86%) participants completed the 18-month visit. Compared with participants randomized to standard F&S!, F&S! Plus participants maintained longer-term benefits at 12 months in weight (mean change ± SE: -1.7 ± 0.3 kg for F&S! Plus vs -0.9 ± 0.3 kg for F&S!, p = 0.049), BMI (-0.6 ± 0.1 vs -0.3 ± 0.1 kg/m2, p = 0.04), waist circumference (-2.7 ± 0.6 vs -0.4 ± 0.6 cm, p = 0.004), and lower extremity strength (1.6 ± 0.2 vs 1.0 ± 0.2 chair stands, p = 0.046). At 18 months, F&S! Plus participants showed improved lower extremity strength (1.4 ± 0.2 vs. 0.7 ± 0.2 chair stands, p = 0.045. African American older adults in the F&S! Plus arm showed sustained modest improvements in weight, waist circumference, and lower extremity strength at 12 months and in lower extremity strength at 18 months compared to F&S!. Implications for the translation of evidence-based programs into community settings to support healthy behaviors in older adults are discussed.

Abstract
BACKGROUND AND OBJECTIVES We compared the effectiveness of standard Fit & Strong! (F&S!; targets physical activity [PA]) to Fit & Strong! Plus (F&S! Plus; targets PA and dietary weight loss) on weight, diet quality, and PA outcomes. RESEARCH DESIGN AND METHODS We randomly assigned 413 overweight older adults with OA to the F&S! or F&S! Plus programs and assessed outcomes at 2 and 6 months. RESULTS The F&S! Plus group lost -2.0 ± 0.2 kg (mean ± SE, 2% of starting weight) at 2 months that was maintained at 6 months. Two- and 6-month BMI and waist circumference improved significantly in the F&S! Plus group (p < .001). Diet quality at 2 months showed greater improvement in the F&S! Plus group: 4.6 ± 0.7 versus 2.0 ± 0.7, p = .006, with no significant difference between groups at 6 months. The F&S! Plus group differentially improved on PA engagement at 2 months and at 2 and 6 months in joint pain (6-month mean ± SE: -1.5 ± 0.3 vs -0.6 ± 0.3, p = .02), function (-4.7 ± 0.9 vs -1.5 ± 0.9, p = .01), and 6-min walk test (29.5 ± 5.1 m vs 14.1 ± 5.2 m, p = .04). DISCUSSION AND IMPLICATIONS Adding a dietary weight loss component to F&S! achieved weight and waist circumference benefits that were maintained at 6 months. Importantly, the weight loss was accompanied by clinically meaningful improvements in OA symptoms and mobility. Future work should investigate minimum thresholds for weight reduction that improve long-term function in this population.

Abstract
Objective: Fatigue is commonly reported by persons with osteoarthritis (OA) and predicts worse functioning and decreased activity. The current research used a combination of wrist and waist accelerometry along with experience sampling methodology to examine the relationship between reports of fatigue and subsequent physical activity among older adults with knee OA. Method: Two hundred one participants completed an interview followed by a 1-week period during which their activity was monitored and they reported symptoms of pain and fatigue. Multilevel models examined within-subjects versus between-subjects patterns of symptoms and their association with physical activity. Results: Fatigue was the most consistent predictor of lowered physical activity (β = −20.83, p < .001). Although wrist-worn actigraphs produced higher averaged activity counts than did waist actigraphs ( t = 34.68, p < .001), multilevel models showed consistent results regardless of placement. Discussion: Fatigue was a consistent predictor of lowered activity regardless of actigraph location.

Abstract
Objectives The prevalence of osteoarthritis (OA) has increased in the US. We report on a comparative effectiveness trial that compares Fit & Strong!, an existing evidence-based physical activity (PA) program, to Fit & Strong! Plus, which combines the Fit & Strong! intervention with a weight management intervention. Methods Participants included 413 overweight/obese (BMI 25-50 kg/m2) adults with lower extremity (LE) OA. The majority of the sample was African-American and female. Both interventions met 3 times weekly for 8 weeks. Primary measures included diet and weight. Results The baseline mean BMI for all participants was 34.8 kg/m², percentage of calories from fat was high, and self-reported PA was low. Discussion This sample of overweight/obese African-American adults had lifestyle patterns at baseline that were less than healthful, and there were differences between self-report and performance-based measures as a function of age.

Abstract
As international collaborations increase, occupational therapists are becoming aware of the advantages of using consistent measures to compare outcomes of assessments across cultures. However, the translation of a measurement tool from one language to another may present issues that have to be addressed. This paper examines the advantages and issues related to the use of one tool, the Arthritis Impact Measurement Scale (AIMS). It meets the goals of the World Health Organization (WHO, 1980, 1993), and it appears to meet the purpose of users in several countries, thereby eliminating the need to develop a new tool. Instead, the AIMS has been translated into several languages. This paper examines three translated versions of the AIMS and discusses the issues related to the process of translation of the tool.

Abstract
The rheumatology community began incorporating patient-reported outcomes in the early 1980s, helping shift the care of chronic diseases from a narrower biomedical model to a broader biopsychosocial model of health. Early efforts were focused primarily in clinical trials and clinical research, but over the last decade there has been increasing use in routine rheumatology clinical care. More than 250 valid and reliable scales to assess domains of importance to patients with rheumatic conditions have been developed. The approach to measurement continues to be refined. Rheumatology has much to be proud of in contributions to the important field of patient-reported outcomes.

Abstract
The objective of the study was to perform a systematic review to identify and appraise outcome measures and measures of pain that are used to assess the experience of pain by older people with osteoarthritis, and to assess whether these measures are effective at capturing the multidimensional nature of the experience of this pain. A systematic review of five electronic databases from January 1996 to March 2013 was done. Inclusion criteria were cohort/observational and cross-sectional studies; specific diagnosis of OA; employed outcome measures of pain and/or health and/or quality of life which included questions about pain; and considered older adults. Articles were reviewed for methodological quality using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. A total of 14 publications met the inclusion criteria, and 11 discrete studies were included in the review. The studies used 21 different outcome measures, utilizing 13 measures of pain. Sensory, affective and cognitive dimensions of pain were captured by the measures, albeit studies predominantly measured intensity or severity alone. Measures of pain used in epidemiological studies do not adequately capture the multidimensional nature of the experience of pain in osteoarthritis. There is a fraught complexity in the multidimensionality of the experience of pain in osteoarthritis, and studies exploring osteoarthritis pain in older people should attempt to capture this multidimensionality by employing multiple valid and reliable outcome measures that capture specific dimensions of the pain experience.

Abstract
OBJECTIVES To examine the impact of telephone reinforcement (TR) on predictors of physical activity (PA) maintenance in older adults with osteoarthritis. METHODS Mixed effects modeling was conducted of data from a randomized PA trial that used negotiated maintenance contracts, supplemented by TR, to test impact of TR on barriers, decisional balance, and stage of change at multiple points in time. RESULTS Participants who were referred to a PA program and received TR improved the most in barriers and decisional balance. Participants who negotiated a tailored maintenance contract but did not receive TR improved the most in stage. CONCLUSIONS TR appears to positively affect perceptions around engagement, whereas negotiation positively impacts PA behavior. Further research should examine the effectiveness of specific PA maintenance strategies.

Abstract
Osteoarthritis (OA) is the most common chronic condition and principal cause of disability among older adults. The current obesity epidemic has contributed to this high prevalence rate. Fortunately both OA symptoms and obesity can be ameliorated through lifestyle modifications. Physical activity (PA) combined with weight management improves physical function among obese persons with knee OA but evidence-based interventions that combine PA and weight management are limited for this population. This paper describes a comparative effectiveness trial testing an evidence-based PA program for adults with lower extremity (LE) OA, Fit and Strong!, against an enhanced version that also addresses weight management based on the evidence-based Obesity Reduction Black Intervention Trial (ORBIT). Adult participants (n=400) with LE OA, age 60+, overweight/obese, and not meeting PA requirements of ≥ 150 min per week, are randomized to one of the two programs. Both 8-week interventions meet 3 times per week and include 60 min of strength, flexibility, and aerobic exercise instruction followed by 30 min of education/group discussion. The Fit and Strong! education sessions focus on using PA to manage OA; whereas Fit and Strong! Plus addresses PA and weight loss management strategies. Maintenance of behavior change is reinforced in both groups during months 3-24 through telephone calls and mailed newsletters. Outcomes are assessed at baseline, and 2, 6, 12, 18, and 24 months. Primary outcomes are dietary change at 2 months followed by weight loss at 6 months that is maintained at 24 months. Secondary outcomes assess PA, physical performance, and anxiety/depression.

Abstract
Chronic disease management requires the individual to perform varying forms of self-care behaviors. Self-efficacy, a widely used psychosocial concept, is associated with the ability to manage chronic disease. In this study, we examine the association between self-efficacy to manage hypertension and six clinically prescribed hypertension self-care behaviors. We interviewed 190 African Americans with hypertension who resided in the greater metropolitan Charlotte area about their self-efficacy and their hypertension self-care activities. Logistic regression for correlated observations was used to model the relationship between self-efficacy and adherence to hypertension self-care behaviors. Since the hypertension self-care behavior outcomes were not rare occurrences, an odds ratio correction method was used to provide a more reliable measure of the prevalence ratio (PR). Over half (59%) of participants reported having good self-efficacy to manage their hypertension. Good self-efficacy was statistically significantly associated with increased prevalence of adherence to medication (PR = 1.23, 95% CI: 1.08, 1.32), eating a low-salt diet (PR = 1.64, 95% CI: 1.07-2.20), engaging in physical activity (PR = 1.27, 95% CI: 1.08-1.39), not smoking (PR = 1.10, 95% CI: 1.01-1.15), and practicing weight management techniques (PR = 1.63, 95% CI: 1.30-1.87). Hypertension self-efficacy is strongly associated with adherence to five of six prescribed self-care activities among African Americans with hypertension. Ensuring that African Americans feel confident that hypertension is a manageable condition and that they are knowledgeable about appropriate self-care behaviors are important factors in improving hypertension self-care and blood pressure control. Health practitioners should assess individuals' self-care activities and direct them toward practical techniques to help boost their confidence in managing their blood pressure.

Abstract
OBJECTIVES We examined the effects of 2 worksite health-promotion interventions (compared with a health-education control) on older workers' healthy behaviors and health outcomes. METHODS We conducted a prospective, randomized controlled trial with 423 participants aged 40 years and older. Participants were categorized into 3 study arms: the COACH intervention combined Web-based risk assessments with personal coaching support, the RealAge intervention used a Web-based risk assessment and behavior-specific modules, and a control group received printed health-promotion materials. Participants were assessed at baseline, 6 months, and 12 months. Random-effects modeling controlled for baseline stage of change for all behaviors of interest in all groups. RESULTS At 6 and 12 months, COACH participants showed significantly increased fruit and vegetable consumption (P = .026; P < .001) and participation in physical activity (P = .05; P = .013), and at 12 months they showed decreased percentage of energy from fat (P = .027). RealAge participants showed significantly decreased waist circumference at 6 and 12 months (P = .05; P = .018). CONCLUSIONS COACH participants were twice as likely to use the COACH intervention as RealAge participants were to use the RealAge intervention. COACH participants experienced twice the number of positive outcomes that control participants experienced.

Abstract
PURPOSE OF THE STUDY African Americans often experience early onset of hypertension that can result in generations of adults managing high blood pressure concurrently. Using a model based on the Theory of Interdependence, this study examined whether intergenerational transmission of hypertension knowledge and self-efficacy would affect hypertension self-care of older parents and their adult children. DESIGN AND METHODS We recruited 95 African American older parent-adult child dyads with hypertension. We constructed separate logistic regression models for older parents and adult children with medication adherence as the outcome. Each model included individual demographic and health characteristics, the partner's knowledge, and self-efficacy to manage hypertension and dyad-related characteristics. RESULTS Parents were more adherent with medication than adult children (67.4% vs. 49.5%, p < .012). There were no significant factors associated with parent medication adherence. In adjusted models for adult children, medication adherence was associated with child's gender (odds ratio [OR] = 3.29, 95% confidence interval [CI] = 1.26-8.59), parent beliefs that the child had better hypertension self-care (OR = 4.36, 95% CI = 1.34-14.17), and child reports that the dyad conversed about hypertension (OR = 3.48, 95% CI = 1.18-10.29). Parental knowledge of hypertension and parent's self-efficacy were weakly associated with adult children's medication adherence (OR = 1.35, 95% CI = 0.99-1.84 and OR = 2.59, 95% CI = 0.94-7.12, respectively). IMPLICATIONS Interventions should consider targeting African American older adults to increase self-care knowledge and empower them as a primary influencer of hypertension self-care within the family.

Abstract
OBJECTIVE Fit and Strong! is an award winning, evidence-based, multiple-component physical activity/behavior change intervention. It is a group- and facility-based program that meets for 90 minutes 3 times per week for 8 weeks (24 sessions total). We originally tested Fit and Strong! using physical therapists (PTs) as instructors but have transitioned to using nationally certified exercise instructors (CEIs) as part of an effort to translate Fit and Strong! into community-based settings, and have tested the impact of this shift in instruction type on participant outcomes. METHODS We used a 2-group design. The first 161 participants to sequentially enroll received instruction from PTs. The next 190 sequential enrollees received instruction from CEIs. All participants were assessed at baseline, at the conclusion of the 8-week Fit and Strong! program, and at the 6-month followup. RESULTS We saw no significant differences by group on outcomes at 8 weeks or 6 months. Participants in both groups improved significantly with respect to lower-extremity strength, aerobic capacity, pain, stiffness, and physical function. Significant differences favoring the PT-led classes were seen on 2 of 5 mediators, self-efficacy for exercise and barriers adherence efficacy. Participant evaluations rated both types of instruction equally highly, attendance was identical, and no untoward health events were observed or reported under either instruction mode. CONCLUSION Outcomes under the 2 types of instruction are remarkably stable. These findings justify the use of CEIs in the future to extend the reach of the Fit and Strong! program.

Abstract
In designing a study protocol relating to hip fracture treatment and outcomes, it is important to select appropriate outcome instruments. Before beginning the process of instrument selection, investigators must gain a comprehensive understanding of the condition of interest and have a thorough knowledge of the expected benefits and harms of the proposed intervention. Adequate evidence of an intervention's effectiveness includes indication of impact on the patient's health. We provide a brief discussion about different ways that health and health measurement have been defined, including the International Classification of Function, Disability and Health (ICF), health-related quality of life (HRQOL), and cost-to-benefit analyses. We outline important properties (reliability, validity, sensitivity to change, and responsiveness) that a measurement instrument must demonstrate before being considered an acceptable means to measure outcome. Potential outcome measures relevant to patients with hip fracture are summarized, and important points to consider in the selection of outcome measures for a hypothetical research question in a hip fracture population are discussed.

Abstract
PURPOSE We present final outcomes from the multiple-component Fit and Strong! intervention for older adults with lower extremity osteoarthritis. DESIGN AND METHODS A randomized controlled trial compared the effects of this exercise and behavior-change program followed by home-based reinforcement (n=115) with a wait list control (n=100) at 2, 6, and 12 months. Fit and Strong! combined flexibility, aerobic walking, and resistance training with education and group problem solving to enhance self-efficacy for exercise and maintenance of physical activity. All participants developed individualized plans for long-term maintenance. RESULTS Relative to controls, treatment participants experienced statistically significant improvements in self-efficacy for exercise (p=.001), minutes of exercise per week (p=.000), and lower extremity stiffness (p=.018) at 2 months. These benefits were maintained at 6 months and were accompanied by increased self-efficacy for adherence to exercise over time (p=.001), reduced pain (p=.040), and a marginally significant increase in self-efficacy for arthritis pain management (p=.052). Despite a substantially smaller sample size at 12 months, significant treatment-group effects were maintained on self-efficacy for exercise (p=.006) and minutes of exercise per week (p=.001), accompanied by marginally significant reductions in lower extremity stiffness (p=.056) and pain (p=.066). No adverse health effects were seen. Effect sizes for self-efficacy for exercise and for maintenance of physical activity were 0.798 and 0.713, and 0.905 and 0.669, respectively, in the treatment group at 6 and 12 months. IMPLICATIONS This consistent pattern of benefits indicates that this low-cost intervention is efficacious for older adults with lower extremity osteoarthritis.

Abstract
OBJECTIVE This study examined direct vs indirect associations of pain and physical function with depression in 369 older adults with osteoarthritis (OA) of the knee. A key focus was the distinction of functional disability in necessary tasks (basic and instrumental activities of daily living) from discretionary, leisure activities. DESIGN A naturalistic longitudinal study examined effects of demographic variables, indicators of arthritis status, general health, pain, and several measures of functional disability upon depressive symptoms at baseline and 1 year later. SETTING AND PATIENTS Participants with diagnosed knee OA were recruited from rheumatological and general geriatric outpatient clinics, as well as public service announcements. OUTCOME MEASURE Depressive symptoms, measured with the Center for Epidemiologic Studies Depression scale. RESULTS At baseline, the relationships of depression with functional disability and activity limitation were wholly mediated by pain. In contrast, activity participation was independently linked with depression, even controlling health and demographic variables. A 1-year follow-up revealed that depressive symptoms increased with increasing health problems, and with reduction in activity participation over time. Having and retaining favorite pastimes were also associated with reduced depressive symptomatology at baseline and follow-up, respectively. CONCLUSIONS These data highlight the disease-specific nature of paths among depression, pain, and disability, and the importance of considering discretionary as well as necessary activities in evaluating effects of pain upon quality of life.

Abstract
This paper represents an expert-based consensus statement on pain assessment among older adults. It is intended to provide recommendations that will be useful for both researchers and clinicians. Contributors were identified based on literature prominence and with the aim of achieving a broad representation of disciplines. Recommendations are provided regarding the physical examination and the assessment of pain using self-report and observational methods (suitable for seniors with dementia). In addition, recommendations are provided regarding the assessment of the physical and emotional functioning of older adults experiencing pain. The literature underlying the consensus recommendations is reviewed. Multiple revisions led to final reviews of 2 complete drafts before consensus was reached.

Abstract
OBJECTIVE In order to develop a hand assessment questionnaire for a population survey, a systematic review was undertaken of measures of hand disability. The purpose of this review was to identify valid measures to evaluate hand osteoarthritis (HOA) in the general population and primary care and to perform a quality appraisal of them. METHOD Measurement tools were identified from an online search of databases (Medline, CINAHL and Institute for Scientific Information (ISI), 1990-2002) restricted to English language and adult population. Search terms combined "osteoarthritis" and "arthritis" with "hand" and ["function" or "disability" or "outcome"]. Instruments used in the evaluation of HOA were identified following application of strict eligibility criteria. The use of these tools in HOA was rated by pairs of independent reviewers according to criteria developed by the Medical Outcomes Trust. RESULTS The initial search yielded a list of articles which were not mutually exclusive (ISI, 127; Medline, 64; CINAHL, 61). Full journal articles were ordered from relevant abstracts (ISI, 28; Medline, 3; CINAHL, 5). Further hand searching of articles produced an additional 34 references. A total of 61 references were identified, 18 measurement tools, 5 of which met the inclusion criteria [Algofunctional Index (FIHOA), Arthritis Impact Measurement Scale 2 (AIMS2), Stanford Health Assessment Questionnaire (HAQ), Australian/Canadian Osteoarthritis Hand Index (AUSCAN), Cochin]. Overall, the AIMS2 and AUSCAN were more highly rated than the FIHOA, Cochin and HAQ. CONCLUSIONS The aim of this review was not to recommend any one instrument over another but to provide an overall summary of the robustness of commonly used measures. The choice of instrument will depend on many factors, and will differ from project to project depending on the question asked.

Abstract
PURPOSE This study assessed the impact of a low cost, multicomponent physical activity intervention for older adults with lower extremity osteoarthritis. DESIGN AND METHODS A randomized controlled trial compared the effects of a facility-based multiple-component training program followed by home-based adherence (n = 80) to a wait list control group (n = 70). Assessments were conducted at baseline and at 2 and 6 months following randomization. The training program consisted of range of motion, resistance training, aerobic walking, and education-group problem solving regarding self-efficacy for exercise and exercise adherence. All training group participants developed individualized plans for posttraining adherence. RESULTS Relative to the persons in the control group, individuals who participated in the exercise program experienced a statistically significant improvement in exercise efficacy, a 48.5% increase in exercise adherence, and a 13.3% increase in 6-min distance walk that were accompanied by significant decreases in lower extremity stiffness at 2 and 6 months. Program participants also experienced a significant decrease in lower extremity pain and a borderline significant improvement in efficacy to adhere to exercise over time at 6 months (p =.052). In contrast, persons in the control group deteriorated over time on the efficacy and adherence measures and showed no change on the other measures. No adverse health effects were encountered. IMPLICATIONS These benefits indicate that this low-cost intervention may hold great promise as one of a growing number of public health intervention strategies for older adults in the United States with osteoarthritis.

Abstract
OBJECTIVE To develop a comprehensive set of explicit process measures to assess the quality of health care for osteoarthritis, rheumatoid arthritis, and analgesics use. METHODS Potential quality measures and a summary of existing data to support or refute the relationship between the processes of care proposed in the indicators and relevant clinical outcomes were developed through a comprehensive literature review. The proposed measures and literature summary were presented to a multidisciplinary panel of experts in arthritis and pain. Using a modification of the RAND/UCLA Appropriateness Method, the panel rated each proposed measure for its validity as a measure of health care quality. RESULTS Among 66 proposed indicators, the expert panel rated 51 as valid measures of health care including 14 for osteoarthritis, 27 for rheumatoid arthritis, and 10 for analgesics use. CONCLUSIONS Sufficient scientific evidence and expert consensus exist to support a comprehensive set of measures to assess the quality of heath care for osteoarthritis, rheumatoid arthritis, and analgesics use. These measures can be used to gain an understanding of the quality of care for patients with arthritis.

Abstract
The population of industrialized countries is aging rapidly. Rheumatologic disorders are the most common illnesses causing functional disability in the elderly and medications for rheumatologic disorders are among the most frequently prescribed. As the population of patients seen by rheumatologists ages, it is important for the rheumatologist to understand the techniques of geriatric assessment that are useful in understanding and treating this special population. This article reviews practical ways to assess function, cognition, affect, directives, and end-of-life care in elderly populations. The article concludes with a "Top Ten" list of geriatric principles for rheumatology fellows to learn.

Abstract
The role of response stability in the measurement of coping is examined with a focus on the unique information that can be gleaned from low test retest reliability ('inconsistency'). Data from two studies are presented in which a card sort measure of coping flexibility was used on people with three different chronic diseases and the elderly (n = 219). We begin by testing the hypothesis that the low stability reflects unreliability due to measurement artifacts, such as random error, low ecological validity, long test retest interval, surrogate assistance, or error due to completing the questionnaire in multiple sittings. Our findings suggest that surrogate assistance in completing questionnaires was the only measurement artifact associated with low stability. We then tested the proposition that low stability reflects a genuine behavior pattern (i.e. inconsistency). Hierarchical modeling revealed that measurement artifact accounted for less than one percent of the variance in inconsistency in reported coping behavior and that an additional 21% of the variance could be explained by the behavioral factors, including neuropsychological problems (9%), psychological morbidity (4%), locus of control (3%) and eudaimonistic well-being (5%). Thus inconsistency in reported coping behavior was better explained by behavioral and psychosocial factors than by the tested measurement artifacts. We conclude that inconsistency in reported coping behavior does indeed reflect a meaningful behavior pattern, rather than simply measurement artifact.

Abstract
A variety of reliable and valid psychosocial assessment instruments have been developed. Many of these instruments are brief and easily incorporated into clinical practice settings. Measures of coping, self-efficacy, helplessness, and cognitive distortion are especially useful in understanding the pain experience in rheumatic disease populations. Information gleaned from psychosocial assessments is increasingly being used to guide pain treatment efforts. Recent research, suggests that treatment outcomes can be improved if one tailors psychosocial pain management protocols to address the particular problems identified by comprehensive psychosocial assessments. Considered overall, psychosocial assessment methods have much to offer the clinician working with patients having persistent pain. The current status of this field is promising, and as psychosocial assessment methods become even more fully integrated into clinical practice, they are likely to yield even greater insights into the pain experience of patients with rheumatic diseases.

Abstract
The objective of this study was to assess the longitudinal impact of joint impairment on overall disability and crossing domain-specific thresholds for physical activity, mobility, dexterity, instrumental activities of daily living (IADL), and activities of daily living (ADL) that are associated with use of long-term care. This 4-year longitudinal study observed 484 persons older than age 60. Logistic regression assessed the contribution of demographics, psychological mediators, lower- and upper-extremity joint impairment, and comorbidities to increased domain-specific self-reported disability above a threshold associated with use of long-term care. Lower-extremity joint impairment and age predicted crossing thresholds by year 4 in physical activity, mobility, IADL, and ADL disability that were associated with use of long-term care. Lower-extremity joint impairment is a strong risk factor for future disability that is associated with use of long-term care.

Abstract
OBJECTIVE This review highlights the clinical and pathophysiologic features of osteoarthritis (OA) of the peripheral joints and discusses the current and future management options for this common but potentially disabling disease. This article also addresses the contribution of osteoarthritis to falls and functional impairment in older people. DESIGN A critical assessment of current data regarding the pathogenesis of osteoarthritis, current and future therapies, and the potential role of OA in falls and functional impairment in older people. CONCLUSIONS Osteoarthritis is the most prevalent articular disease in older adults. Disease markers that will detect early disease and allow early intervention with pharmacologic agents that modify, if not halt, disease progression are much needed, but they are presently unavailable. Current management should include safe and adequate pain relief using systemic and local therapies and should also include medical and rehabilitative interventions to prevent, or at least compensate for, functional deficits. Although OA can result in impaired mobility and lower extremity function, its contribution as a cause of recurrent falls or impaired self-care, relative to other comorbid conditions, remains ill-defined. Further analysis of the determinants of disability, loss of mobility and falls in older patients with OA is needed.

Abstract
BACKGROUND AND OBJECTIVE A variety of outcome measures are used in evaluating disease activity and therapeutic efficacy in rheumatoid arthritis (RA) studies, and this makes comparisons of drug efficacy difficult. Some of the endpoints used are not standardized and/or are insensitive to change. The purpose of this report is to present a critical appraisal of outcome measures and quality of life assessments in RA studies. METHOD An overview of the literature was undertaken to determine the extent to which there is consensus among experts in this area of research. RESULTS The data suggest that the core set of endpoints in RA clinical studies should include tender joint count swollen joint count, patients' assessment of pain, patients' and physicians' global assessments, patients' assessment of physical function and acute phase reactant level. When trials of disease-modifying antirheumatic drugs (DMARD) last for more than a year, radiography may be useful. A 'pooled index' may be valuable, and its construction is discussed. Quality of life (QoL) instruments facilitate a fuller examination of the effects of health care interventions and these should be used to complement the more traditional clinical endpoints in the core set. The instruments most commonly used in RA research are identified. CONCLUSIONS We conclude that randomized clinical trials of treatments in RA should now ideally use the core set of clinical endpoints and validated QoL instruments for assessing safety and efficacy.

Abstract
OBJECTIVE To determine factors that predict change in walking velocity in older people using a multivariate model. DESIGN Longitudinal observational study. SUBJECTS A total of 588 persons older than age 60, including subjects residing in a continuing care retirement community (CCRC) (n = 248), and homebound (n = 79) and ambulatory (n = 261) subjects. Mean age at baseline = 77. MEASUREMENT Independent variables included demographics, physician measures of lower-extremity joint impairment and other musculoskeletal and neurological variables, comorbidities derived from physical examination and chart abstract, self-assessed arthritis pain, depression, and anxiety. The major dependent variables were 2- and 4-year decline in walking velocity below a threshold associated with nursing home placement. MAIN RESULTS From baseline to Year 4, median walking velocity declined from 61.8 to 53.0 m/min, and the proportion of subjects above a threshold value of 11.5 m/min declined from 95.3% to 80.4%. Age, joint impairment, and weakness of quadriceps, measured at baseline, predicted 2-year and 4-year decline in walking velocity. CONCLUSIONS The findings indicate that joint impairment and quadriceps strength contribute significantly to crossing a clinically significant threshold in walking velocity among older people over time. Future research is needed to determine whether these risk factors can be modified through preventive interventions such as muscle-strengthening exercises and pain medication.

Abstract
OBJECTIVE To review that what is known about the prevalence and impact of arthritis on disability and health care expenditures incurred by older persons. METHODS The current prevalence estimates of osteoarthritis and osteoporosis in the US are examined, and what is known about the relationship of arthritis, broadly defined to disability, and the impact of arthritis-specific disability on home care and nursing home use by older persons are reviewed. RESULTS Arthritis is a major contributor to disability among older people and is especially disabling for older women, who have higher prevalence rates and greater disability than their male counterparts. Studies of the relationship of arthritis to long-term care use indicate that arthritis can be a risk factor insofar as it can cause disability that results in homeboundedness, which, in turn is a risk factor for nursing home use. It is possible that previous analyses that included arthritis and disability as competing risk factors for nursing home use underestimate the contribution of arthritis because arthritis is a risk factor for disability; thus, the two variables may be strongly correlated. CONCLUSIONS More study is needed to understand the contribution of sex to prevalence of arthritis and severity of arthritis-specific disability. The route through which arthritis affects long-term care use also needs careful longitudinal study. If arthritis is confirmed to be a major risk factor for disability that leads to long-term care use, the development and testing of interventions to prevent/minimize arthritis-specific disability should be a major research priority.

Abstract
OBJECTIVE To determine predictors of walking velocity in the elderly. METHODS Five hundred thirty-two persons from 3 cohorts of elderly persons (retirement community, ambulatory care medical clinic, or chronically homebound population) performed a 10-foot (for the homebound subjects) or 50-foot (for all other subjects) walk time test and underwent a standardized interview, chart review, and clinical examination. The 73 independent variables that were evaluated included demographic, musculoskeletal, neurologic, psychologic, and other comorbidity items. Least-squares and least-absolute-deviation regression tree analyses were performed to determine the strongest predictive factors associated with walking velocity. RESULTS Sampling cohort (homebound versus non-homebound), quadriceps strength, hip flexion strength, lumbosacral spine impairment, lower joint impairment, and education were found to be associated with walking velocity. Joint pain measures were not associated with walking velocity. CONCLUSION Muscle strength variables are better predictors of walking velocity than are joint pain variables. Thus, clinical trials and observational studies using walking velocity as an outcome need to take into consideration the influence of muscle strength on this outcome variable.

Abstract
OBJECTIVE To validate a hierarchical model of hand function in older persons, using longitudinal data. DESIGN Longitudinal observational study (2-year data from an ongoing longitudinal study). SUBJECTS 689 persons older than age 60, including Continuing Care Retirement Community (n = 230), homebound (n = 204), and ambulatory (n = 255) respondents. Mean age at baseline 76.6 (SD = 8.8). MEASUREMENT Independent variables included sociodemographics, physician measures of upper joint impairment, self-reported comorbidity, arthritis pain, depression, and anxiety. The dependent variables included grip strength and a timed manual performance test. MAIN RESULTS Using generalized estimated equations (GEE) to test our hierarchial model, we found that gender and upper extremity joint impairment were the strongest predictors of a longitudinal measure of grip strength. Grip strength, in turn, along with demographics, comorbidity, and a measure of psychological status, was significantly related to timed manual performance. CONCLUSIONS The longitudinal analyses confirmed a previous cross-sectional finding that upper extremity joint impairment contributes significantly to reduced grip strength, which, in turn, contributes to reduced hand performance on a timed test.

Abstract
OBJECTIVE The objective of this study was to compare two methods of measuring physical function in subjects with a broad range of abilities and to evaluate the effects of cognitive, social, educational, and age factors on the relationship between the two methods. DESIGN Multiple regression analysis was used to compare self-perceived (dependent variables) with performance measures (independent variables). Covariates included age, gender, Mini-Mental State Exam score, education, living status, and depression score. SETTING Five community-dwelling and two nursing home sites. PARTICIPANTS 417 community-dwelling subjects and 200 nursing home residents aged 62-98 years. MEASUREMENTS Self-perceived physical function was assessed with the physical dimension summary score of the Sickness Impact Profile, which comprises three subscales: ambulation, mobility, and body care and movement. Physical performance was evaluated by self-selected gait speed, chair-stand time, maximal grip strength, and a balance score. RESULTS Nursing home residents and community-dwellers were significantly different (P < .0001) in all variables except age and gender. Self-perceived and performance-based measures were moderately correlated, with a range from r = -.194 to r = -.625 (P < .05). Gait speed was the strongest independent predictor of self-perceived physical function in both groups. Symptoms of depression were also an independent predictor of self-perceived function in nursing home residents; subjects who had such symptoms report more self-perceived dysfunction than would be predicted based on performance tests. CONCLUSIONS Self-selected gait speed is a global indicator of self-perceived physical function over a broad range of abilities. External determinants (depressive symptoms, cognitive function, marital status, etc.) affect self-perceived function in both groups, but gait speed is the greatest single predictor of self-perceived function. In nursing home residents depressive symptomatology is related to self-perceived.

Abstract
OBJECTIVE To test the impact of joint impairment on ambulation in the elderly, using a multivariate model. DESIGN Cross-sectional observational study (baseline data from an ongoing longitudinal study). SUBJECTS Five hundred thirty-two persons over age 60, including continuing care retirement community (CCRC) (n = 222), homebound (n = 63), and ambulatory (n = 247) respondents. Mean age at assessment = 76.6 (SD = 6.6). MEASUREMENT Independent variables included sociodemographics, physician measures of lower joint impairment, an index of cormorbidities derived from physical examination or chart abstract, self-assessed arthritis pain, depression, and anxiety. The dependent variable, ambulation, was measured as walk-rate, based on the time required to walk 50 feet. MAIN RESULTS For the total sample, 61% of the subjects were impaired in more than one lower joint group, with almost 50% of the homebound impaired in more than three joint groups. Demographics (particularly age and education) explained much of the variance in walk-rate. After controlling for demographics and membership in the groups purposely sampled (CCRC, homebound, ambulatory), lower joint impairment accounted for an additional 7% of the variance in walk-rate. Total amount of variance explained by the model was 56% (Adjusted R2 = .56). A 3-point change in lower joint impairment score, equivalent to the maximum impairment score for a single joint group, is associated with a 4-second change in the mean time required to walk 50 feet. The knee and lower spine joints contributed most to the impact of the lower joint impairment measure. CONCLUSIONS Among the elderly, age and education are strong predictors of performance on a walk-rate test. Independent of demographics and non-musculoskeletal conditions, joint impairment is associated with diminished walking ability in this population.

Abstract
This study examined the extent and nature of bias associated with self-reported versus standardized physician-examination/assessment-based accounts of musculoskeletal disease in a sample of 406 persons chosen to represent an aging and dependency continuum. Prevalence of musculoskeletal disease based on standardized physician examination/assessments was 97%. Using the standardized findings as the criterion, the self-report underestimated prevalence by 16%. Overall, the results indicated that self-reports of musculoskeletal conditions by the elderly capture the vast majority of persons with painful or functionally significant disease and are most valid for persons from ages 65 to 74 but do not reflect the presence of asymptomatic joint pathology. Standardized physician examinations/assessments would more accurately determine the presence of risk factors in epidemiological studies of musculoskeletal disability.

Abstract
Chronic arthritis may have great impact on the patient but also on his or her family, relatives and friends. The assessment of the consequences of chronic arthritis and the effect of therapy not only in terms of physical, but also psychological and social dimensions deserves more attention. Functional ability and health status can be measured using a questionnaire or 'instrument', high-lighting important aspects not quantified with more traditional measurements. In this paper, arguments to apply such instruments more frequently are given. Health status instruments can be used not only to assess beneficial but also deleterious (side-) effects of therapeutic interventions. The properties are summarized of the most frequently used instruments assessing functional ability and health status. Many of these instruments have been evaluated sufficiently for validity and reliability; their sensitivity to detect change seems to be satisfactory. Therefore it is advisable to choose an internationally accepted, frequently used instrument, reflecting the area of interest.

Abstract
OBJECTIVE To test the contribution of joint impairment to observed hand function (grip strength and Williams Test) in the elderly, using a multivariate model. DESIGN Cross-sectional observational data (baseline data from an ongoing longitudinal study). SUBJECTS Five hundred forty-one persons over age 60, including continuing care retirement community (n = 222), homebound (n = 72), and ambulatory (n = 247) respondents. Mean age at assessment 76.7, (SD = 9.0). MEASUREMENT Independent variables included sociodemographics, physician measures of upper joint impairment, an index of comorbidities derived from physical examination or chart abstract, self-assessed arthritis pain, depression, and anxiety. The dependent variables included grip strength and a modified Williams Test [Williams Test (M)]. MAIN RESULTS The multiple regression explained 59% (Adjusted R2 = .59) of the variance in grip strength, with joint impairment accounting for a change in R2 of .07. Upper joint impairment and grip strength accounted for 3% and 5%, respectively, of the variance in the Williams Test (M) (total amount of explained variance = 45%). CONCLUSIONS Demographics explain most of the variance in grip strength and performance on the Williams Test (M). Controlling for demographics, musculoskeletal disease represented by joint impairment is associated with diminished grip strength. Reduced grip strength is associated with poorer performance on the Williams Test (M).

Abstract
OBJECTIVE To test the hypothesis that self-reported functional status predicts change in level of care from independent to dependent in residents of a continuing care retirement community (CCRC). DESIGN Two-year longitudinal descriptive study of change in level of care and survival. SUBJECTS One hundred fifty-two residents in the independent-living unit of a non-profit CCRC. Mean age at initial evaluation was 82.3 years, SD 6.2. MEASUREMENT Predictor variables assessed at baseline were age, sex, physician estimate of functionally significant disease, self-reported functional status, and performance-based hand function. Criterion variables collected at 2-year follow-up were level of care (independent/dependent) and survival (alive/dead). MAIN RESULTS Self-reported functional status (P less than 0.01) and age (P less than 0.05) were significant predictors of change in level of care in a logistic regression analysis containing all predictor variables. No variable predicted survival. CONCLUSIONS Self-reported functional status may help to predict dependency in older adults in good health who have few markers of dependency risk.

Abstract
OBJECTIVE The goal of this project was to develop a more comprehensive and sensitive version of the Arthritis Impact Measurement Scales (AIMS). METHODS AIMS scale items were revised, and 3 new scales were added to evaluate arm function, work, and social support. Sections were also added to assess satisfaction with function, attribution of problems to arthritis, and self-designation of priority areas for improvement. The new instrument was designated the AIMS2. A pilot test of format and content and a performance test of reliability and validity were carried out. RESULTS Questionnaire completion times in a pilot study of 24 subjects averaged 23 minutes, and evaluations were positive regarding the instrument's length and ease of completion, and the subjects' willingness to complete serial forms and return them by mail. Measurement performance was tested in 408 subjects: 299 with rheumatoid arthritis (RA) and 109 with osteoarthritis (OA); 45 of these subjects completed a second AIMS2 within 3 weeks. Internal consistency coefficients for the 12 scales were 0.72-0.91 in the RA group and 0.74-0.96 in the OA group. Test-retest reliability was 0.78-0.94. All within-scale factor analyses produced single factors, except for mobility level in OA. Validity analyses in both the RA and the OA groups showed that patient designation of an area as a problem or as a priority for improvement was significantly associated with a poorer AIMS2 scale score in that area. Reliability, factor analysis, and validity results were consistent in age, sex, and education subgroups. Satisfaction was moderately correlated with level of function in the same health status area, and the satisfaction items formed a reliable scale. Responses to the arthritis attribution items showed that most dysfunction in this sample was due to arthritis. CONCLUSION The AIMS2 is a revised and expanded health status questionnaire with excellent measurement properties that should be useful in arthritis clinical trials and in outcomes research.

Abstract
Rheumatoid arthritis (RA), once considered a benign and nonprogressive disease, is a debilitating condition with serious physical, emotional, and economic consequences. It afflicts approximately 1% of the adult population worldwide; prevalence increases with age, with twice as many women as men affected. In the United States, age, lack of formal education, and lower socioeconomic class correlate with both the incidence and poor prognosis of RA. The patient with RA faces increasing functional disability, the likelihood of work disability within 10 years after the onset of the disease, and a drastic reduction in earnings. Compared with individuals without the disease, patients with RA incur higher medical care costs, increased hospitalization, and a greater number of physician visits. As in the general population, the leading cause of death among patients with RA is cardiovascular disease, and deaths due to malignancy occur at a comparable incidence; however, patients with RA are at greater risk of mortality due to infection, renal disease, respiratory conditions, and gastrointestinal disease. Life expectancy is shorter among patients with RA than in the general population, and survival rates are comparable to those for Hodgkin's disease, diabetes mellitus, stroke, and three-vessel coronary artery disease. Efforts must be made to develop improved therapeutic strategies and rehabilitative programs to improve the quality of life of patients with RA.

Abstract
Preventing or minimizing functional dependency in older adults rests, in part, upon the ability to predict who is at risk. The purpose of this study was to compare the ability of five tests of hand function to discriminate the degree of dependency in older adults. Seven hundred sixty four subjects were assessed for hand function on performance-based (Williams Test of Hand Function, a test of Williams Board items only, Jebsen Test of Hand Function, grip strength), and self-reported (Dexterity Scale of the Geriatrics-Arthritis Impact Measurement Scale (GERI-AIMS] measures of hand function, and self-reported multidimensional functional status (GERI-AIMS). A trichotomous variable representing a continuum of dependency based upon living site (independent living, home-bound, institutional) was used as the measure of dependency. Sixty-two cases were dropped for incomplete data. Discriminant function analyses of the 702 subjects (age X = 76.78 years, SD = 8.79) showed that basic demographic variables explain 40.8% of the variance in dependency; all hand function tests significantly correlated with dependency; the Williams Board correlated best (additional 12.5% variance explained). However, a multidimensional functional status measure explains substantially more variance in dependency (16.9%) after controlling for demographic variables and performance on the Williams Board. This comparison of methods and tests available for measuring hand function was made to provide criteria for selecting an instrument for a given setting.
