Reliability of the Nottingham Adjustment Scale Japanese Version on Stroke Survivors in Japan

Abstract

Backgrand and Aims : The Nottingham Adjustment Scale are applied to measure psychological adjustment. The purpose of this study was to confirm the reliability and internal consistency of Nottingham Adjustment scale Japanese Version (NAS-J) on stroke survivors in Japan. Methods : The reliability was proved using test-retest procedure. A Self-rating questionnaire was mailed to 124 community dwelled stroke survivors twice with a 21-24 days interval. Forty-five stroke survivors who returned the first and the second questionnaire and answered every item completely, participated in this study. Spearman's correlation and Wilcoxon signed-ranks test were used to compare the NAS-J scores between the 1^st and 2^nd response. Cronbach's alpha was used to confirm its internal consistency. Results : Scores of the NAS-J between the 1^st and 2^nd response were correlated significantly (p‹0.05), which the coefficients were ranged from 0.41 to 0.79. No significant difference was found between the test and the retest. Cronbach's alpha in each domain ranged from 0.72 to 0.85 except at the domain "Locus of Control" (0.46). Conclusions : The results showed the reliability and the internal consistency of the NAS-J was generally good on stroke survivors in Japan.
