The validity and reliability of the Turkish version of the psychological preparedness for disaster threat scale.

UNLABELLED

The aim of this research was to investigate the validity and reliability of a Turkish version of the 26-item Australian Psychological Preparedness for Disaster Threat Scale (PPDTS). A cross-sectional study involving 530 university students and staff at Giresun University was conducted to establish the psychometric properties of the PPDTS. Content analysis, exploratory factor analysis, confirmatory factor analysis and Cronbach alpha values for reliability were used to analyse the data. Content analysis showed that one item needed to be dropped as it was not related to environmental threats to Turkish communities. The exploratory factor analysis indicated that 66% of the total variance was explained by three factors: (i) knowledge and management of the external situational environment, (ii) management of one's emotional and psychological response, and (iii) management of one's social environment. The confirmatory factor analysis showed acceptable overall goodness of fit for the three-factor model: CFI (0.908), RMSEA (0.074) for the 21 item scale. Cronbach's α coefficients of the subscales were 0.91, 0.93, and 0.83, respectively, while for the whole scale, it was 0.95. Four items from the original PPDTS were deleted in the course of the analyses. It was concluded that the Turkish version (PPDTS-T21) is a valid and reliable assessment tool for the evaluation of levels of psychological readiness for disaster threats to Turkish communities and will be useful in policy making for community preparedness for disaster events.
