Measuring upper limb capacity in poststroke patients: development, fit of the monotone homogeneity model, unidimensionality, fit of the double monotonicity model, differential item functioning, internal consistency, and feasibility of the Stroke Upper Limb Capacity Scale, SULCS.
This paper only describes the results of the internal pilot and feasibility study.
The psychometric properties such as feasibility, internal consistency reliability, item-subscale correlations and construct validity were evaluated.
Psychometric properties were evaluated from the aspect of feasibility, internal consistency reliability, test-retest reliability, content validity, construct validity and discriminant validity.
An internal pilot and feasibility study has been undertaken in the first year to allow refinements to the sample size as well as to assess the feasibility of trial recruitment plans and the proposed interventions.
Consequently, the objective of this study was to develop an NF1 specific HRQOL instrument (as a Module of the PedsQL™) and to test for its initial feasibility, internal consistency reliability and validity.
The objective of this study was to develop an NF1 HRQOL instrument as a module of PedsQL™ and to test for its initial feasibility, internal consistency reliability and validity in adults with NF1.
Compared with other generic health status instruments, the SF-36 has been shown to have better feasibility, internal consistency, content validity and discriminative ability, and to be more responsive to clinical improvement [ 21, 22].
We believe that the questionnaire is still appropiate for the following reasons: first, the patients answered the question correctly on their affected joint; secondly, despite some missing items the questionnaire responses have shown its feasibility, internal validity, reliability and sensitivity to change.
This study aimed at evaluating the psychometric properties of the Chinese version of the PedsQL™ 3.0 Asthma Module, including the feasibility, internal consistency reliability, test-retest reliability, item-subscale correlations, construct validity and concordance between child self-reports and parent proxy-reports.
