Japanese Adaptation of the Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39): Comparative Study among Different Types of Aphasia


      We have developed a Japanese version of the Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39), designated as SAQOL-39-J, and used psychometric methods to examine its acceptability and reliability.


      The acceptability and reliability of SAQOL-39-J, which was developed from the English version using a standard translation and back-translation method, were examined in 54 aphasia patients using standard psychometric methods. The acceptability and reliability of SAQOL-39-J were then compared among patients with different types of aphasia.


      SAQOL-39-J showed good acceptability, internal consistency (Cronbach's α score = .90), and test–retest reliability (intraclass correlation coefficient = .97). Broca's aphasia patients showed the lowest total scores and communication scores on SAQOL-39-J.


      The Japanese version of SAQOL-39, SAQOL-39-J, provides acceptable and reliable data in Japanese stroke patients with aphasia. Among different types of aphasia, Broca's aphasia patients had the lowest total and communication SAQOL-39-J scores. Further studies are needed to assess the effectiveness of health care interventions on health-related quality of life in this population.
