Description

Loss of motivation is frequently recognized in poststroke patients, and it disturbs rehabilitation and recovery in activities of daily living. We evaluated the reliability and validity of the Japanese version of Starkstein's Apathy Scale and compared the scale with an objective assessment (SKETCH Scale) in 135 poststroke patients. The Japanese Apathy Scale displayed a high reliability (ρ=0.963; p<0.0001, n=20) and validity (sensitivity, 81.3%; specificity, 85.3%) with a cutoff point of 16. When compared with the SKETCH scale, the scale also showed a high sensitivity and specificity. The distribution of the Apathy Scale with grade of objective scale revealed a significantly high correlation with the severity of motivational loss and emotional disturbance. Moreover, the score for the Apathy scale and the total scores for the objective assessment were significantly correlated to motivational loss and emotional disturbance. We concluded that the Japanese version of Apathy Scale is reliable and valid for making clinical assessments and is useful for evaluating mild motivational impairment in stroke patients.
