The individual ECM format used in this study did not reduce MS-related fatigue and restrictions in participation more than an information-only control condition.
ABSTRACT. de Laat FA, Rommers GM, Geertzen JH, Roorda LD. Construct validity and test-retest reliability of the Questionnaire Rising and Sitting Down in lower-limb amputees. Arch Phys Med Rehabil 2011;92:1305-10.Objective: To investigate the construct validity and testretest reliability of the Questionnaire Rising and Sitting Down (QR&S), a patient-reported measure of activity limitations in rising and sitting down, in lower-limb amputees.Design: Cross-sectional study. Setting: Outpatient department of a rehabilitation center. Participants: Lower-limb amputees (Nϭ171; mean age Ϯ SD, 65Ϯ12y; 71% men; 83% vascular cause) participated in the study, 33 of whom also participated in the reliability study.Interventions: Not applicable. Main Outcome Measures: Construct validity was investigated by testing 8 hypotheses: limitations in rising and sitting down according to the QR&S would be: (1) greater in lowerlimb amputees who are older, (2) independent of level of amputation, (3) greater in lower-limb amputees with a bilateral amputation, and (4) greater in lower-limb amputees who had rehabilitation treatment in a nursing home. Furthermore, limitations in rising and sitting down will be positively related to activity limitations according to (5) the Locomotor Capabilities Index (LCI), (6) the questions about rising and sitting down in the LCI, (7) the Climbing Stairs Questionnaire, and (8) the Walking Questionnaire. Construct validity was quantified with an independent t test and Pearson correlation coefficient. Testretest reliability was assessed with a 3-week interval and quantified with the intraclass correlation coefficient (ICC), standard error of measurement, and smallest detectable difference (SDD).Results: Construct validity (7 of 8 null hypotheses not rejected) and test-retest reliability were good (ICCϭ.84; 95% confidence interval, .65-.93; standard error of the measurementϭ6.7%; SDDϭ18.6%).Conclusions: The QR&S has good construct validity and good test-retest reliability in lower-limb amputees.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
