Construct Validity and Test-Retest Reliability of the Climbing Stairs Questionnaire in Lower-Limb Amputees

de Laat FA, Rommers GM, Geertzen JH, Roorda LD. Construct validity and test-retest reliability of the Climbing Stairs Questionnaire in lower-limb amputees.

Objective

To investigate the construct validity and test-retest reliability of the Climbing Stairs Questionnaire, a patient-reported measure of activity limitations in climbing stairs, in lower-limb amputees.

Design

A cross-sectional study.

Setting

Outpatient department of a rehabilitation center.

Participants

Lower-limb amputees (N=172; mean ± SD age, 65±12y; 71% men; 82% vascular cause) participated in the study; 33 participated in the reliability study.

Interventions

Not applicable.

Main Outcome Measure(s)

Construct validity was investigated by testing 10 hypotheses: limitations in climbing stairs according to the Climbing Stairs Questionnaire will be greater in lower-limb amputees who: (1) are older, (2) have a vascular cause of amputation, (3) have a bilateral amputation, (4) have a higher level of amputation, (5) have more comorbid conditions, (6) had their rehabilitation treatment in a nursing home, and (7) climb fewer flights of stairs. Furthermore, limitations in climbing stairs will be related positively to activity limitations according to: (8) the Locomotor Capabilities Index, (9) the Questionnaire Rising and Sitting down, and (10) the Walking Questionnaire. Construct validity was quantified by using the Mann-Whitney U test, Kruskal-Wallis test, and Spearman correlation coefficient. Test-retest reliability was assessed with a 3-week interval and quantified using the intraclass correlation coefficient (ICC).

Results

Construct validity (8 of 10 null hypotheses not rejected) and test-retest reliability were good (ICC=.79; 95% confidence interval, .57-.90).

Conclusion

The Climbing Stairs Questionnaire has good construct validity and test-retest reliability in lower-limb amputees.     

Reliability and Internal Consistency of the Activities-Specific Balance Confidence Scale

ABSTRACT

The Activities-specific Balance Confidence Scale (ABC) was developed to assess balance confidence. While several researchers have used the ABC to measure balance confidence, its psychometric properties are reported by only a few studies. The purpose of this study was to evaluate the ABC's test–retest reliability and internal consistency among a sample of community dwelling older adults. Forty-four subjects aged 65 and older who lived independently in a senior living community participated in the study. Each participant completed the ABC on two separate test days, 6 months apart. Test–retest reliability revealed an intraclass correlation coefficient of 0.879 (95% CI, 0.779–0.934). Internal consistency measured by cronbach's α was 0.973 for both baseline and six-month data. The ABC demonstrated good test–retest reliability and strong internal consistency among a sample of community dwelling older adults; however, internal consistency may be exceedingly high, indicating item redundancy.     

Headache Disability Inventory (HDI): Short-term Test-Retest Reliability and Spouse Perceptions

We have reported previously that the 25-item Headache Disability Inventory has good internal consistency reliability, robust long-term (2 month) test-retest stability, and good construct validity. We conducted further investigations to evaluate the short-term (1 week) test-retest reliability and spouse perceptions of patients' self-perceived headache disability. The short-term test-retest reliability of the Headache Disability Inventory was excellent. Additionally, the spouse and patients' perceptions of the patient's headache disability generally were congruent, although we observed instances where the differences were marked.
