A cross-sectional study of the association between Heberden’s nodes, radiographic osteoarthritis of the hands, grip strength, disability, and pain. The scree test plots eigenvalues against factors.
The HAQ was developed as a comprehensive measure of outcome in patients with a wide variety of rheumatic diseases, including rheumatoid arthritis, osteoarthritis, lupus, scleroderma, ankylosing spondylitis, fibromyalgia, and psoriatic arthritis. The items cover five domains, which are work, social, energy and vitality, feeling and concerns, and qeustionnaire. Correlations are also adjusted for age and sex. Results support the validity of the AUSCAN in a general sample of adults, as well as across demographic and clinical subgroups, although the subscale structures differed slightly by race.
Prior studies have confirmed the validity of this scale in clinical and family-based samples, all with radiographic hand OA 1 — 5. Partial correlations for subgroups gender, race, all age groups, radiographic hand OA, hand pain showed patterns similar to those shown for the total sample data not shownexcept for a few minor deviations.

The HAQ should be considered a generic rather than a disease-specific instrument. Results of the exploratory factor analysis with the number of factors not specified are shown in Table IV for the full sample.
Specifically, the grip and pinch strength were more strongly associated with the AUSCAN function subscale than the pain and stiffness subscales. Results for the total sample are not shown but were similar to the factor loadings for the Caucasian group shown in Table V.
A First Course in Factor Analysis. We examined the internal consistency, construct validity, and factor structure of the AUSCAN among the total sample, as well as in subgroups according to gender, race, presence of hand pain, and presence of radiographic hand osteoarthritis OA.

This may indicate some weakness in the questjonnaire validity and specificity of the AUSCAN pain subscale among these subgroups. We chose to retain two factors because the AUSCAN items in suscan analyses are intended to represent two subscales pain and function. Patients and methods Subjects The cross-sectional sample was composed of individuals enrolled in the Johnston County Osteoarthritis Project who completed the AUSCAN during a follow-up assessment approximately 5—7 years after their baseline assessment.
In addition, we used an alternate classification of hand OA to examine whether results differed if a less strict definition of OA was employed. To questionnxire construct validity of the AUSCAN subscales, the function subscale should have the highest correlation with hand strength, and the pain sub-scale should have the highest correlation with the single-item pain measure.
However, we did not observe a clear factor pattern corresponding to activity type in this analysis. This study examined measurement properties of the AUSCAN in a large, community-based sample, extending knowledge about the scale’s generalizability. Stratford PW, Kennedy D. We then questinnaire a second factor analysis, constrained asucan two factors. When controlling for the AUSCAN function subscale, the pain subscale was still significantly associated with the right and left hand pain items.

Studies have shown this measure has acceptable reliability, construct validity, and responsiveness 1 — 5. The questionnaire consists of 15 questions that are evaluated on a 7-level Likert scale. It would be valuable to examine whether these cognitive processes vary according to race and other demographic characteristics.
Correlations with the right and left hand pain items were similar for all three subscales. We conducted factor analyses with two factors specified on these two separate Caucasian groups and found that the factor loadings were similar to each other and to those for the full sample. Because it is not possible to have a single-item factor, the AUSCAN stiffness subscale was excluded from all factor analyses.
The racial differences observed in this study add to prior research showing that African Americans and whites differ in their experience and descriptions of pain 7 Briefly, this study involved civilian, noninstitutionalized adults aged 45 years and older who resided in six townships in Johnston County.
