The source language is English for USA. Correlations involving the AUSCAN stiffness scale and the self-reported hand pain are Spearman correlation coefficients; other correlations are Pearson correlation coefficients. This analysis allowed us to test the associations of each subscale with strength and pain while controlling for the other subscale.

Validity and factor structure of the AUSCAN Osteoarthritis Hand Index in a community-based sample

Validation of an algofunctional index for osteoarthritis of the hand. We chose to retain two factors because the AUSCAN items in the analyses are intended to represent two subscales pain and function. 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 For the total sample, all pain subscale items clearly loaded on one factor and all function items on another.

Therefore Spearman’s rank-order quuestionnaire was used for any correlations involving either of these two variables.

Because the subscales may not discretely measure pain and function as expected, their sensitivity to change may not be optimal when used independently rather than as part of a total AUSCAN score. Next, we conducted qeustionnaire analyses with two factors specified, since the AUSCAN items we included were intended to measure two constructs pain and function.

The impact of arthritis in rural populations. Please review our privacy policy. Because it is not possible to have a single-item factor, the AUSCAN stiffness subscale was excluded from all factor analyses.

Results support the validity of the AUSCAN in a general sample of adults, as well as questiinnaire demographic and clinical subgroups, auscann the subscale structures differed slightly by race.

The function items that loaded on the factor with the pain items relate to tasks that generally require less strength turning faucets and doorknobs, buttoning than the remainder of the function items that loaded on a factor together i.

Factor analysis showed that for the full sample and most subgroups, all pain items loaded on one factor standardized regression coefficients 0.

Cronbach’s alpha levels were lowest for participants with no self-reported hand pain, but these were still well within the acceptable range 0. These results suggest that for African Americans, the AUSCAN pain and function subscales may not measure two discrete domains of pain and function as expected.

Partial correlations of the AUSCAN pain and function subscales with the single-item pain and hand strength measures also supported the subscales’ construct validity among the total sample and most subgroups. Overall, results suggest that the AUSCAN has acceptable measurement properties and can be a valuable quwstionnaire for assessing the impact of OA on pain and quesyionnaire in the community.

These partial correlations were also age- and sex-adjusted. We then conducted a second factor analysis, constrained to two factors. Iceland Israel Italy Korea Lebanon. Correlations between AUSCAN subscales and the hand strength and hand pain measures support the scale’s construct validity. It would be valuable to examine whether these cognitive processes vary according to race and other demographic characteristics.

Several of these have been made available for distribution through us by their developers. To support the construct validity of these subscales, the function subscale should remain significantly associated with strength when controlling for the questionbaire subscale, and the pain subscale should remain significantly associated with the single-item pain measures when controlling for function. With respect to gender, associations of AUSCAN subscales with pinch and grip strength were slightly qkestionnaire for men than women, but these were all statistically significant for both groups and followed patterns similar to those shown in Table II.

The remainder had not yet been read, and those participants were excluded from analyses stratified by hand OA status.

Australian/Canadian Osteoarthritis Hand Index (AUSCAN)

Translated and Validated Questionnaires Health Outcomes Group has translated and linguistically validated many questionnaires over the years. Based on previous research 5we expected moderate correlations among the subscales, but very high correlations may indicate overlap between the scales.

For exceptions, permission may be sought for such use through Elsevier’s permissions site at: Because sample size can influence factor analytic results and thus may have contributed to the observed differences between Caucasian and African American groups, we randomly divided the Caucasian participants in the sample into two groups that were approximately the same size as the African American group.

Factor Analysis Results of the exploratory factor analysis with the number of factors not specified are shown in Table IV for the full sample. Internal consistency was also acceptable for all subgroups, including men and women, Caucasians and African American, all age groups, those with and without radiographic hand OA using both definitionsand those with and without self-reported hand pain.

Open in a separate window. Cronbach’s alpha measures the extent to which items measure the same characteristic The HAQc is a parent administered questionnaire and has been used extensively in children with rheumatoid arthritis. Construct validity was confirmed against a variety of measures, including the Dreiser Index 11 Briefly, this scale assesses: Prior studies have involved small clinical samples 1 — 3 and family-based samples 45.

The cross-sectional sample was composed of individuals enrolled in the Johnston County Auecan Project who completed the AUSCAN during a follow-up assessment approximately 5—7 years after their baseline assessment. Correlations with the right and left hand pain items were similar for all three subscales.
