Section snippets
Materials and methods
The patient self-report section of the ASES is a condition-specific scale—that is, it is designed for a specific condition, which is intended to measure functional limitations and pain of the shoulder. The original ASES21 consists of 2 portions, a medical professional assessment section and a patient self-report section. The patient self-report section, evaluated in this study, is a patient self-evaluation questionnaire that takes approximately 5 minutes to complete and consists of 2
Reliability
Test-retest reliability was calculated with the use of 1-way ICCs, the results of which are shown in Table III.The internal consistency estimate of Cronbach α was.86.19
Error estimates
The error associated with a single application (SEM) and multiple applications (MDC/SRD) of the patient self-report section of the ASES was calculated; the results are shown in Table III.
Validity
The correlations (95% CI) for the assessment of convergent validity were significant betweenthe patient self-report section of the ASES and the
Discussion
In the present health care climate, there is an ever-increasing demand to demonstrate the efficacy of therapeutic interventions. Because of this need self-report instruments have been developed to assess the impact of a disease on a patient's functional limitations and disability. However, in order for an outcome measure to be interpreted and used, these instruments must have documented psychometric properties.
To assess reliability, the patient self-report section of the ASES was administered 1
