“…The original AIMS questionnaire contained 45 items grouped into 9 scales (6). These scale scores could in turn be combined to produce overall models of health status, with 3 or 5 components (7,8). The measurement properties of the AIMS, including its reliability, validity, and sensitivity to change, have been reported (9)(10)(11)(12).…”

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 -2.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. Mea- Submitted for publication February 20, 1991; accepted in revised form August 19, 1991. surement 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 withm-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.

“…Several aspects of physical health status were measured in at least 1 of the 3 studies. Studies 1 and 3 included 4 subscales from the AIMS that have been identified as components of lower extremity function: Physical Activity, Mobility, Activities of Daily Living, and Household Activities (20). The reliability and validity of these scales in arthritis populations have been demonstrated by previous research (8,19,21,22).…”

Using data from 3 studies of patients with rheumatoid arthritis, we examined the extent to which responses to items in the Center for Epidemiological Studies Depression Scale (CES-D) are influenced by aspects of the disease process other than depression. Our findings suggested that 4 CES-D items (i.e., "I felt that everything I did was an effort," "I felt hopeful about the future," "My sleep was restless," and "I could not get going") may be influenced by aspects of the disease process and, thus, are not necessarily indicative of depression among persons with arthritis. The impact that these items have on the interpretation of CES-D scores was assessed in relation to 2 research issues: estimation of the prevalence and severity of depression in arthritis populations and identification of the determinants of depression among individuals with arthritis. Our results suggest that the original CES-D may overestimate the prevalence and severity of depression among patients with arthritis. The magnitude of this bias is modest, however. The results also suggest that in studies designed to identify the determinants of depression among individuals with arthritis, inclusion of the 4 items identified is unlikely to have any effect on study findings.

“…The higher the score on the AIMS scales the worse the health status. Pre vious research [9] has revealed that the 9 AIMS scales contain the following 5 components of health status: (I) upper extremity function; (2) lower extremity function; (3) affect; (4) symptom, and (5) social inter action. Table 1 shows the relationship between the 9 AIMS scales and these 5 components of health status.…”

Patients with systemic lupus erythematosus (SLE) and a comparison group of patients with rheumatoid arthritis (RA) completed the Dutch Everyday Problem Checklist and the Dutch Arthritis Impact Measurement Scale measuring physical and psychosocial aspects of illness. Both scales were completed 9 times at 6-week intervals. In addition several hematological and serological parameters were assayed. Analysis over several time points resulted in only weak correlations between the variables under study. The most remarkable finding of this study was that in SLE patients number and intensity of daily stressors are more strongly related to physical and psychosocial status than in RA patients.
