“…A traditional method of assessing responsiveness involves correlating a change in the instrument score with changes in physiologic measures (22). More recent methods include reporting a difference in scores, reporting an effect size (calculated by dividing the change score by the baseline standard deviation), or reporting the standardized re-sponse mean (calculated by dividing the change in score by the standard deviation of the difference) (20,21,23,24).…”

Objective. To evaluate the measurement properties of the Health Assessment Questionnaire (HAQ) disability index (DI) for group comparisons in scleroderma trials, and to determine if the Scleroderma Health Assessment Questionnaire (SHAQ) visual analog scales confer any measurement advantage over the HAQ DI. Methods. A computer search for articles describing the use of the HAQ DI and SHAQ in scleroderma was performed. Evidence supporting the sensibility, reliability, validity, and responsiveness of these measures was evaluated. Results. The SHAQ has incremental face and content validity over the HAQ DI because it addresses scleroderma-specific manifestations that also contribute to disability. The HAQ DI has good concurrent validity, construct validity, and predictive validity. Whether SHAQ confers incremental construct, concurrent, or predictive validity over the HAQ DI is uncertain. The HAQ DI appears more reliable than the SHAQ; however, reliability studies provide insufficient data to ascertain if minimum standards have been achieved. Responsiveness of the HAQ DI subscales has been demonstrated. INTRODUCTIONThe Health Assessment Questionnaire (HAQ) disability index (DI) and the Scleroderma Health Assessment Questionnaire (SHAQ) are instruments increasingly utilized to assess scleroderma patients in randomized trials (1-4). The HAQ DI is a measure of disability developed for rheumatoid arthritis patients. It is valid, reliable, and responsive to change in this population (5,6). The HAQ DI contains 8 domains of activity (dressing, arising, eating, walking, hygiene, reach, grip, and common daily activities) each of which has at least 2 questions, for a total of 20 items. For each item, patients report the amount of difficulty experienced performing the activity. There are 4 possible responses for each item ranging from 0 (without any difficulty) to 3 (unable to do). A mean score is calculated for each domain ranging from 0 to 3. A composite HAQ DI score is calculated by dividing the summed domain scores by the number of domains answered. The composite score is reported, falling between 0 and 3 on an ordinal scale. The scores are interpreted as 0 (no impairment in function) to 3 (maximal impairment of function) (7).The HAQ-DI also contains a visual analog scale (VAS) that patients use to report the amount of pain experienced in the past week. The VAS is a 15-cm line that is converted to a continuous scale from 0 to 3 where 1 cm is equivalent ). To obtain the patient score, a metric ruler is used to measure the distance in centimeters from the left anchor to the patient's mark, and then multiplied by 0.2 (8). The VAS pain score is not incorporated into the HAQ DI composite score.Steen and Medsger extrapolated use of the HAQ DI to scleroderma patients. Believing the HAQ DI was inadequate to evaluate the multisystem effects of scleroderma, they added 5 scleroderma-specific VASs, thereby creating the SHAQ (8) (See Appendix A available at the Arthritis Care & Research Web site at http://www.interscience. wiley.com/jp...

“…The SIP68, a generic measure used for assessing the impact of illness on daily functioning and behavior [41][42], consists of 68 items that are all dichotomously scored. The items are categorized into six subscales: somatic autonomy (e.g., getting dressed, transfers), mobility control (behavior related to walking and arm function), psychological autonomy and communication (e.g., concentration, alertness, talking), emotional stability (the effect of health status on emotional behavior), social behavior, and "mobility range" (instrumental daily activities).…”

Abstract-This study evaluated the responsiveness of the Canadian Occupational Performance Measure (COPM), an individualized, client-centered outcome measure for the identification and evaluation of self-perceived occupational performance problems. We recruited 152 consecutive patients with various diagnoses, admitted to the outpatient clinic of two occupational therapy departments, to complete a COPM interview and three self-reported health status questionnaires on two occasions: prior to the start of occupational therapy treatment and 3 months later. The three questionnaires were the Sickness Impact Profile (SIP68), the Disability and Impact Profile (DIP), and the Impact on Participation and Autonomy (IPA). We assessed criterion responsiveness by calculating the area under the curve (AUC) for the receiver operating characteristic curve and the optimal cutoff values for the COPM scores. To determine construct responsiveness, we calculated correlations between the change in COPM scores and the change in the SIP68, DIP, and IPA scores. The AUC ranged from 0.79 to 0.85, and the optimal cut-off values for the performance scores and satisfaction scores ranged from 0.9 to 1.9. We found significant positive correlations between the COPM scores and the SIP68, DIP, and IPA scores. The capability of the COPM to detect changes in perceived occupational performance issues is supported.
