Abstract: Objective To translate Assessment of Swallowing Ability for Pneumonia (ASAP) from English into Chinese and to evaluate the reliability and validity of Chinese version in Chinese elderly patients with central nervous system diseases. Methods Eight experts were invited to evaluate the content validity of the Chineses version of ASAP. Fifty elderly inpatients with central nervous system diseases were evaluated using the Chinese version of ASAP and Standard Swallowing Assessment (SSA) by one nurse and one rehabilitation doctor, respectively. The evaluation time was compared and the relationship between the two scales was analyzed. Twenty patients were randomly selected, and they were evaluated using the Chinese version of ASAP by the rehabilitation doctor on the same day, and were evaluated again by the nurse on the second day. The internal and external intraclass correlation coefficients (ICC) were calculated. All patients were guided to adjust the eating patterns according to their ASAP grades, and the incidence of aspiration pneumonia (AP) was observed. Results ASAP Chinese version showed good internal consistency among intra-evaluators consistency (ICC=0.93, P<0.001) and inter-evaluator consistency (ICC=0.91, P<0.001); The Cronbach’s α coefficient of each item was 0.913-0.945, while the Cronbach’s α coefficient of the scale was 0.938; Each item content validity index (I-CVI) was 0.875-1.000, and the scale content validity index (S-CVI) was 1, and the average S-CVI was 0.984. ASAP Chinese version was negatively correlated with SSA (r=-0.93, P<0.001), and the evaluation time of ASAP Chinese version was less than that of SSA (7.1±1.8 min vs 19.3±3.0 min, P=0.02). The incidence rate of AP among the patients with moderate abnormal ASAP was significantly higher than that among the patients with normal ASAP or mildly abnormal ASAP (P<0.01). Conclusions ASAP Chinese version shows good reliability and validity in Chinese elderly patients with central nervous system diseases. It is easy, safe and reliable to operate, and needs less evaluation time. Furthermore, the scale can also guide the patients to adjust their eating patterns and reduce the incidence of AP.
