HRQOLISP-26: A Concise, Multiculturally Valid, Multidimensional, Flexible, and Reliable Stroke-Specific Measure

Background . A multidimensional, brief, and flexible stroke-specific health-related quality of life (HRQOL) measure is still needed. The aim was to develop a shortened version of the HRQOLISP-102, a multiculturally generated measure with excellent psychometric properties. Methods . Participants included 100 (Ibadan, Nigeria) and 103 (Berlin, Germany) stroke patients compared to 100 (Ibadan) and 50 (Berlin) apparently healthy adults. Using standard protocol, the 26-item version was generated, consisting of therapeutically relevant physical, psychological, cognitive, and ecosocial domains. Criterion validity of the HRQOLISP-26 was determined using Bland-Altman statistics. “Known groups” validity was assessed using NIHSS, stroke levity score, and modified Rankin scale. Results . HRQOLISP-26 was easily interpretable and precise with no significant floor/ceiling effect. It can be completed within 7 minutes. It showed good content, construct, “known groups,” and criterion validity. It demonstrated good internal consistency ( α = 0.81, 0.89) and test-retest reliability. Conclusions . HRQOLISP-26 is novel, brief, multiculturally-valid, and flexible for routine assessment of HRQOL in stroke patients.
