Prior research on the Western Ontario McMaster University Osteoarthritis Index WOMACan index of lower extremity pain, stiffness, and function 18indicated that scale items clustered according to the type of activity, rather than according to pain, stiffness, and function subscales 19 Correlations within all subgroups gender, race, all age groups, radiographic hand OA, and hand pain were similar to those of total sample.
It assesses the three dimensions of pain, disability and joint stiffness for patients with osteoarthritis of the hip or knee. The potential impact of this differing factor structure of the AUSCAN among African Americans is not clear from these analyses and warrants further research.
Older patients’ perceptions of quality of chronic knee or hip pain: National Center for Biotechnology InformationU. Correlations involving the AUSCAN stiffness scale and the self-reported hand pain are Spearman correlation coefficients; other correlations are Pearson correlation coefficients.
This is likely due to similarity between some activities queried in the pain and function subscales i. 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.
Australian/Canadian Osteoarthritis Hand Index (AUSCAN)
We first conducted an exploratory factor analysis SAS Proc Factor with the number of factors not specified 14 In addition, we used an alternate classification of hand OA to examine questionnairr results differed if a less strict definition of OA was employed.

We did not find substantial differences in the subscales’ associations with single-item pain measures for the right or left hand. Factor analysis showed that for the full sample and most subgroups, all pain items loaded on one factor standardized regression coefficients 0.
Radiographs were obtained by a standard protocol, postero-anteriorly and focused on the third metacarpophalangeal joint. Because the subscales may not discretely qeustionnaire pain and function as expected, their sensitivity to change may not be optimal when used independently rather than auxcan part of a total AUSCAN score.
Radiological assessment of osteoarthrosis. Results of this analysis were similar for men, women, all age questiknnaire, Caucasians, participants with and without radiographic hand OA using both definitionsand participants with and without self-reported hand pain.
Third, this sample also includes a substantial proportion of men, which is important because prior studies using the AUSCAN have involved predominantly samples questionnaier women 1 — 5and the scale’s measurement properties have not been examined specifically among men.
Cronbach’s alphas for the total scale and subscales were above 0. Participants completed grip and pinch strength measures at the same visit as questionnaire measures AUSCAN and self-reported pain. We examined these partial correlations in right and left hands.
For the exploratory factor analysis, we used the scree test to examine the number of factors that best fit the data Partial correlations of the AUSCAN pain and function subscales with the single-item pain and hand strength measures also questionnarie the subscales’ construct validity among the total sample and most subgroups. 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.
When controlling for the AUSCAN function subscale, the pain subscale was still significantly associated with the right and left hand pain items. Author information Copyright and Questionnairf information Disclaimer.

Denmark Finland France Germany Hungry. Iceland Israel Italy Korea Lebanon. Construct validity was also supported, as grip and pinch strength were more strongly correlated with the AUSCAN function subscale than with the pain and stiffness subscales.
With respect to gender, associations of AUSCAN subscales with pinch and grip auecan were slightly weaker for men than women, but these were all statistically significant for both groups and followed patterns similar to those shown in Table II.
For exceptions, permission may questiknnaire sought for such use through Elsevier’s permissions site at: Three of the items on the function subscale loaded on a factor with the five auscsn subscale items.
Among African Americans, there was a more notable difference in the factor structure of the AUSCAN pain and function items when two factors were specified. Cognitive interviewing would quetsionnaire help to examine individuals’ thought processes when responding to these items.
In these analyses, the single-item pain measure was more strongly associated with the AUSCAN pain subscale than the function subscale, except among individuals in the middle age group 55—64; in which the correlation with the AUSCAN function subscale was very slightly higher and those without radiographic hand OA in which these associations were approximately equal.

Therefore Spearman’s rank-order coefficient was used for any correlations involving either of these two variables. Conclusions Results support the validity of the AUSCAN in a general sample of adults, as well as across demographic and clinical subgroups, although the subscale ascan differed slightly by race. For the total sample, all pain subscale items clearly loaded on one factor and all function items on another.
The eigenvalue for a given factor measures the variance in quesionnaire variables that is accounted for by that factor.
