validity and reliability of online assessment

This large population of internal migrants is predominantly comprised of workers employed in factories, making Shenzhen a suitable location for sampling in studies related to this demographic. The city of Shenzhen boasts a resident population of 17.68 million, making it the largest internal migrant city in China. Defeat was positively associated with anxiety and depression and might play an important role in the mental health of IMWs. Conclusions: DS performed well among IMWs on content validity and structural validity, and it was suitable as a measurement instrument to assess defeat among this population.

Logistic regression showed that DS scores were positively associated with anxiety and depression among IMWs. Cronbach’s alpha reliability coefficient for the DS was 0.92. There were 606 (33.6%) IMWs who were considered to have depression symptoms, and 524 (29.0%) IMWs were considered to have anxiety symptoms. Results: Mean score of DS among IMWs was 18.42 ± 9.40. Logistic regression was performed to explore the effects of DS scores on anxiety and depression. Convergent validity and discriminant validity were estimated by calculating the average variance extracted and composite reliability. The scree test was used to determine the number of factors. Cronbach’s coefficient alpha of each factor and the total scale were calculated to assess the reliability of DS.

The content validity index (CVI) was used to assess content validity. Methods: 1805 internal migrant workers (IMWs) were recruited by stratified multistage sampling from 16 factories in Shenzhen, China. This study aimed to verify the content validity and structural validity of the DS among internal migrant workers in China and to explore its correlations with anxiety and depression. But its reliability and validity among internal migrant workers have not been reported. The defeat scale (DS) can measure the feeling of defeat, social hierarchy reduction, and loss in social struggle. It has been reported that defeat might play a prospective role in predicting depression and anxiety however, defeat is rarely explored among internal migrant workers due to the lack of appropriate measurement scales. Introduction: Internal migrant workers have a great chance to experience defeat due to their low social status and economic situation.
