“…In this study, 339 valid survey questionnaires from 5 communities in three different districts of Shenzhen are analyzed in detail. The Cronbach's alpha of questionnaires reaches 0.811, which representes a high level of reliability [36]. Table 2 summarizes the socio-demographic attributes of gender, age, education and income in the study area.…”

The initial concept of flood control has gradually shifted to flood risk management which emphasizes more public participation. Therefore, understanding the public’s protective coping behavioral patterns to floods is significant, and can help improve the effectiveness of public participation and implementation of flood-mitigation measures. However, the quantitative effect of socio-demographic factors on flood risk perception and behaviors is not clear. In this study, the socio-demographic factors are included to explore the quantitative relationship with and the affect path to flood protective coping behaviors with socio-demographic factors are studied. Shenzhen City in China is chosen as the study area, which suffers frequent urban floods every year. Questionnaire surveys are conducted in five flood-prone communities there, and 339 valid questionnaires were collected. The correlations between flood risk perception, flood risk knowledge, flood risk attitude, socio-demographic factors, and protective coping behaviors are analyzed firstly. A structural equation model (SEM) about these factors is then established to verify the correctness of hypothetical paths and discover new paths. The results indicates that socio-demographic factors and flood risk perception do not have impacts on protective coping behaviors directly, but are mediated by flood risk knowledge and flood risk attitude. Flood risk attitude is an important factor that affects protective coping behaviors directly. Moreover, two affect paths to flood protective coping behaviors are proposed. The findings of Shenzhen city in this study can be extended to other cities with similar characteristics, providing support for conducting effective flood mitigation measures.

“…Five factors explained 60.98% of the total variance (detailed information on the extraction sums of the squared loadings can be seen in Additional file 1: Table S2). All internal consistency coefficients (alpha, a) for the NPPBQ demonstrated acceptable internal consistency [14,15], with all values above the generally accepted threshold of 0.70. Table 3 shows the means (M), standard deviations (SD), reliability values (Cronbach's α), and inter-correlations between the NPPBQ's subdimensions and the correlations with the NPPBQ total score.…”

Background:With the increased empirical interest in the positive significance of improving nurses' sense of professional benefits, there is a requirement for measures of nurses' perceived professional benefit (NPPB). Our objective was to develop and psychometrically test a brief Nurses' Perceived Professional Benefit Questionnaire (NPPBQ).Methods: After expert consultation and nurse interviews, a primary questionnaire was developed for an exploratory factor analysis (EFA). The seventeen items of the NPPBQ were used for verification of the theorized factor structure and content validity using a confirmatory factor analysis (CFA). The NPPBQ's concurrent validity was evaluated. Three samples of nurses were collected in Shanghai, Hangzhou and Nanjing between November 2017 and August 2018.Results: The results of the EFA and CFA verified the five dimensions of nurses' occupational benefit discovery. The results demonstrated that the NPPBQ has adequate internal consistency and is fully consistent with the theorized factor structure. This 5-factor solution explained an adequate percentage of the total variance. The Cronbach's alpha of each dimension of the NPPBQ was good. The concurrent validity was significantly correlated with all aspects of the Maslach Burnout Inventory (MBI). Conclusion: The results suggest that the NPPBQ is a psychometrically sound measure for evaluating perceived professional benefits among a wide range of nurses.
