Reliability of the Self-Report Administration of the ABILHAND Questionnaire in Chronic Stroke

The ABILHAND is among the most widely used questionnaires in upper limb rehabilitation. This study aimed to evaluate whether self-report procedure of the ABILHAND-Stroke is concordant with performance observation-based procedure. Two assessments were performed with each patient on the same day using the Beninese version of the ABILHAND. Intraclass correlation coefficient (ICC2,1) and Bland–Altman plot were used to evaluate the agreement and the relationships between ABILHAND measures. A total of 123 people with chronic stroke were included in the study. ICC was .77 (95% confidence interval [CI] = [.67, .82]) with p < 10 −6 demonstrating a good concordance between both assessment methods despite significant difference between patients’ mean measures (self-report = −0.06 ± 2.64 logit; performance-based = 1.28 ± 3.57 logit; p value < .0001). Results confirmed the concordance of the self-report regarding the performance-based measures. In clinical routine self-report of ABILHAND scale might be useful for initial screening purposes while for further investigation the performance observation-based procedure should be preferred.
