However, for African Americans, a different factor pattern emerged, with three function items loading on a factor with the pain items. The eigenvalue for a given factor measures the variance in all variables that is accounted for by that factor.

All items are rated on a scale of 0 none to 4 extreme.

This may be partly due to the fact that these hand pain items have a limited distribution scale of 0—3 and may not be sensitive to small differences in pain. There was a minor deviation from this pattern for the subgroup of patients who reported that they did not have current hand pain on the single-item measure.

This is particularly important because the AUSCAN scale developers have endorsed the use of the subscales individually 4. Please review our privacy policy. To examine construct validity of the subscales, we assessed correlations of all three AUSCAN subscales with hand strength grip and pinch strength for both right and left hands and the self-reported right and left hand pain four-point scale.

This suggests there may be some item overlap between the subscales. The HAQ should be considered a generic rather than qufstionnaire disease-specific instrument.

We recently reported that among a large sample of adults with familial hand osteoarthritis OAthe AUSCAN showed acceptable factorial validity, with three distinct subscales 5. Partial correlations of the AUSCAN pain and function subscales with the single-item questionnqire and hand strength measures also supported the subscales’ construct validity among the total sample and most subgroups.

Correlations are also adjusted for age and sex.

We first conducted an exploratory factor analysis SAS Proc Questionnaife with the number of factors not specified 14 Details of the protocol are reported elsewhere 8. The racial differences questionnairr in this study add to prior research showing that African Americans and whites differ in their experience and descriptions of pain 7 Iceland Israel Italy Korea Lebanon.

A cross-sectional study of the association between Heberden’s nodes, radiographic osteoarthritis of the hands, grip strength, disability, and pain. To support 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.

The cross-sectional sample was composed of individuals enrolled in the Johnston County Questionnair Project who completed the AUSCAN during a follow-up assessment approximately 5—7 years after their baseline assessment. We examined the internal consistency, construct validity, qeustionnaire 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.

Validation of an algofunctional index for osteoarthritis of the hand. It assesses the three ausdan of pain, disability and joint stiffness for patients with osteoarthritis of the hip or knee. There may be individual differences in the types and difficulty of tasks that individuals think about when responding to pain items i.

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. Partial correlations Spearman represent the association of one subscale with the strength or pain item questionnqire controlling for the other subscale.

AUSCAN – Australian/Canadian Osteoarthritis Hand Index

The items cover five domains, which are work, social, energy and vitality, feeling and concerns, and symptoms. Next, we conducted factor analyses with two factors specified, since the AUSCAN items we included were intended to measure two constructs pain and function.

Furthermore, internal consistency was acceptable for all subgroups we examined, including individuals without self-reported hand pain and individuals without radiographic hand OA.

Correlations with the right and left hand pain items were similar for all three subscales. Stratford PW, Kennedy D. Because the AUSCAN is a relatively new scale, it is important to examine its utility and measurement properties in a variety of populations and settings to evaluate the generalizability of this scale. A First Course in Factor Analysis. Cronbach’s alpha measures the extent to which items measure the same characteristic Kellgren J, Lawrence J. Second, this study sample includes a substantial proportion of African Americans, providing the opportunity to examine the AUSCAN’s measurement properties according to race.

However, as stated above, it also may be related to limitations in our single-item hand pain measures. Please inquire if you do not see your desired questionnaire below as we may have worked with it before. 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.

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 structures differed slightly by race.
