Introduction:
The psychological ability of police law enforcement significantly impacts the effectiveness of on-site law enforcement, but there is currently no effective measurement tool available. This research aims to develop a police law enforcement psychological ability scale and test its reliability and validity.
Methods:
According to the principles and requirements of scale development, 239 law enforcement officers were selected as the study subjects. Then, following theoretical construction, scale development and testing, project analysis, exploratory factor analysis, confirmatory factor analysis, reliability and validity testing, and other procedures, a police law enforcement psychological ability scale was developed.
Results:
The new scale includes three dimensions-cognitive characteristics, emotional capacity, and volition quality-and nine sub-dimensions: attention, thinking, perception, emotion recognition, emotion control, emotion application, decisiveness, resilience, and bravery. The total correlation coefficient of the scale questions ranged from 0.670 to 0.791, and there is a significant positive correlation (P < 0.01). Exploratory factor analysis showed that the KMO test value was 0.954, and the Bartlett sphericity test result had a chi-squared value of 9717.356 (degree of freedom = 861, P < 0.01). The overall internal consistency coefficient of the scale is 0.978, and the coefficients of the cognitive characteristics, emotional capacity, and volition quality subscales are 0.946, 0.962, and 0.937, respectively. Confirmatory factor analysis showed that χ2/df < 3, RMSEA = 0.09, RFI = 0.765, IFI = 0.841, CFI = 0.840, NFI = 0.779, TLI = 0.830, and PNFI = 0.733.
Conclusion:
The model meets the requirements of psychometrics in terms of reliability and validity within an acceptable range and can be used for measuring and evaluating the psychological ability level of police law enforcement.
