BACKGROUND: The 24-item Recovery Assessment Scale (RAS) is the most widely-used and well-validated tool for measuring recovery for people with mental illness. The current study aims to assess the reliability and validity of an 8-item short form of RAS (RAS-8) among a Chinese sample of people living with schizophrenia. METHODS: A sample of 400 people living with schizophrenia were recruited for scale validation. Internal consistency was tested by calculating Cronbach's α. Test-retest reliability was calculated using the intraclass correlation coefficient (ICC) for the total score and weighted kappa for each item. Factor structure was tested with confirmatory factor analysis, and concurrent validity was examined by investigating the correlation of the RAS-8 with patient symptoms, disability, depression, anxiety, patient functioning, quality of life and general health. RESULTS: The RAS-8 full scale and subscales showed good internal consistency with Cronbach's alpha ranging from 0.87 to 0.92. ICC of 0.99 and weighted kappa ranged from 0.62 to 0.88, which generally indicates good test-retest reliability. The findings supported an a priori two-factor structure, χ2/df = 2.93, CFI = 0.98, TLI = 0.98, RMSEA = 0.07, SRMR = 0.035. Concurrent validity of the RAS-8 was further supported by its significant negative correlations with patient symptoms (r = -0.24, p < 0.01), disability (r = -0.30, p < 0.01), depression (r = -0.16, p < 0.05), and anxiety (r = -0.14, p < 0.05), and its significant positive relationships with patient functioning (r = 0.26, p < 0.01), quality of life (r = 0.39, p < 0.01) and general health (r = 0.34, p < 0.01). CONCLUSIONS: This study confirmed the reliability and validity of an 8-item short-form RAS for people living with schizophrenia in Chinese communities. The validation of the RAS-8 allows for its use as an alternative for the full RAS as a rapid assessment tool in clinical and research settings. The findings are discussed for their implications for application and validation with other populations and in other countries.

OBJECTIVE: To evaluate the effect of the water conservancy schistosomiasis control projects in rivers and estuaries connecting with the Yangtze River on Oncomelania snail control. METHODS: Three water conservancy schistosomiasis control projects of Laobianmin River, Panjia River and Bianmin River were chosen for the objects of the study. The concrete slope protection and the overflow dam, the concrete slope protection and the check sluice, and the simple concrete slope protection were built respectively in above mentioned three rivers. The changes of the area with snails and density of snails were investigated before and after the interventions, and the results were compared among the three projects. RESULTS: In the condition of the routine snail control with the molluscicide, the snails were eliminated in the main riverway of the Laobianmin River, but the snails still existed in the target protected area (tributaries of the river and irrigation areas); the snails were eliminated in the Panjia River and its irrigation areas; in the Bianmin River, the areas with snails dropped by 89.22% in the main river and still remained in the tributaries and irrigation areas after the project implementation. CONCLUSIONS: The sluice and overflow dam more contribute to control and eliminate snails in the project areas and the target protected areas in the rivers and estuaries connecting with the Yangtze River. The priority of consideration should be given to the water level control and prevention of snail spreading in the water level instability rivers connecting with the Yangtze River.
