ABSTRACT

Background and Aims

The Japanese Disaster Prevention Consciousness Scale (J‐DPCS) addresses all natural disasters, making it more adaptable to foreign populations. However, certain items in the scale refer to disaster preparedness measures which may not be emphasized in countries where infrastructure development for disaster prevention is less prioritized, hence the need for modification. We aimed to validate the 20‐item J‐DPCS and develop and evaluate the Vietnamese Disaster Prevention Consciousness Scale (V‐DPCS) through a cross‐sectional survey in Japan and Vietnam.

Methods

We surveyed 618 Japanese adults and 496 Vietnamese adults. The J‐DPCS was validated using factor analysis, internal consistency was assessed with Cronbach's αand McDonald's ω, and concurrent validity was examined using the Spearman's rank‐order correlations and bootstrapping. For the V‐DPCS, item difficulty and discrimination were estimated using the Item Response Theory (Two‐Parameter Logistic model). Item‐total correlations with bootstrapping were used to assess reliability. Differences in response scales between Japan and Vietnam were adjusted, and a confirmatory factor analysis was conducted.

Results

Factor analysis revealed a five‐factor structure for both versions, with acceptable internal consistency for most factors. Factor 1 (0.85), 2 (0.79), and 3 (0.80) maintained strong reliability compared to their original values (0.906, 0.863, and 0.868, respectively). Factor 4 had a low reliability coefficient of 0.60 and 0.55 in the original and 20‐item version, respectively. Factor 5 consisted of four items with similar Cronbach's alpha coefficients.

Conclusion

The 20‐item J‐DPCS demonstrated strong validity and reliability. The validated core model of the V‐DPCS, consisting of 12 items across Factors 1–3, is suitable for cross cultural application. However, Factors 4 and 5 require further development to enhance measurement stability. These findings underscore the complexities of adapting disaster prevention scales across cultures and support the utility of the core V‐DPCS structure in diverse settings.

Abstract

Respiratory rate is a critical parameter for activating rapid response systems. Given the limitations of existing respiratory rate measurement methods, we aimed to develop a simple, affordable, portable, non-contact, and automatic measurement device using commercially available optical components. We further verified its measurement accuracy through experiments involving a simulator and a volunteer. The proposed system consisted of a webcam with 10 infrared light-emitting diodes, a webcam arm stand, and a laptop. The system employed the law of light attenuation to assess changes in the distance between the camera and the body surface and then extracted depth information from two-dimensional images. In the simulator experiments, the Bland–Altman analysis revealed a bias of 0.167 between simulator settings and automatic system measurements, and 0.200 between simulator settings and visual measurements by a nurse. In the volunteer experiment, the bias between automatic system measurements and visual measurements by a nurse was 0.033. The results were satisfactory. The proposed method exhibits sufficient measurement accuracy for practical use in an individual with a stable respiratory state. Collectively, our findings suggest that the device could reduce observational burden on nurses and significantly improve recording rate of respiratory parameters.
